Rock burst will happened when the underground engineering is excavated in the hard and brittle rock mass because of high in situ stress or concentrated stress. The length of Qirehataer diversion tunnel is 15.639km,and the maximum over-depth is 1720m. With excavation of tunnel, lightly to moderate rock burst had taken place in 600m length about of tunnel, and moderate rock burst locally. The mainly lithology of tunnel is gneiss granite and the percent is 64.5%, uniaxial compressive strength of which is 63.5MPa so it should be classified hard rock. The maximum principle stress is 30MPa in the place of rock bust. This paper analysis engineering geology conditions of this area and the characters of rock burst, author concludes that posteriority and continuity for time and Traceability and continuity for place are different from others rock burst examples. The reason is that course of stress adjustment is continually and repetitive.

This study aims to investigate physical mechanisms of locally concentrated nearshore hydrodynamic forces under interactive fields of waves and currents on abruptly changing coastal bathymetry. Laboratory experiments were first performed to represent such phenomena and a newly developed monitoring system based on image processing techniques successfully captured the local concentrations of wave fields as quantitative high-resolution data sets. Numerical experiments were then performed to investigate the physical mechanisms of the observed features. It was found that, among the other various possible factors, slowly varying wave-induced nearshore currents have one of the most significant impacts on local concentrations of waves around the abruptly changing bathymetry.

Accurate and timely misfire fault diagnosis is of vital significance for diesel engines. However, existing algorithms are prone to fall into model over-fitting and adopt low energy-concentrated features. This paper presents a novel extreme gradient boosting-based misfire fault diagnosis approach utilizing the high-accuracy time–frequency information of vibration signals. First, diesel engine misfire tests were conducted under different spindle speeds, and the corresponding vibration signals were acquired via a triaxial accelerometer. The time-domain features of signals were extracted by using a time-domain statistics method, while the high-accuracy time–frequency domain features were obtained via the high-resolution multisynchrosqueezing transform. Thereafter, considering the nonlinearity and high dimensionality of the original characteristic data sets, the locally linear embedding method was employed for feature dimensionality reduction. Eventually, to avoid model overfitting, the extreme gradient boosting algorithm was utilized for diesel engine misfire fault diagnosis. Experiments under different spindle speeds and comprehensive comparisons with other evaluation methods were conducted to demonstrate the effectiveness of the proposed extreme gradient boosting-based misfire diagnosis method. The results verify that the highest classification accuracy of the proposed extreme gradient boosting-based algorithm is up to 99.93%. Simultaneously, the classification accuracy of the presented approach is approximately 24.63% higher on average than those of algorithms that use wavelet packet-based features. Moreover, it is shown that it obtains the minimum root mean squared error and can effectively prevent the model from falling into overfitting.

Intellectual disability was recognised in ancient Indian literature, but organised services have a history of just five decades. India shares many features of low- and middle-income (LAMI) countries regarding intellectual disability. There is a low level of awareness about its nature, causes and interventions. One can come across many superstitions, myths and misconceptions about intellectual disability. In general, services are inadequate, being concentrated in big cities and urban areas. There is generally limited access to support services and few government benefits, and these, in any case, are often of little value (World Health Organization, 2007). Locally and nationally, there are few relevant and reliable epidemiological data on the prevalence of intellectual disability. However, there have been some positive developments within the past three decades, and they are the focus of this paper.

Global and local features are essential for visual-similarity texture perception. Therefore, understanding how people allocate their visual attention when viewing textures with global or local similarity is important. In this work, we investigate the influences of global and local features of a texture on eye-movement patterns and analyze the relationship between eye-movement patterns and visual-similarity selection. First, we synthesized textures by separately controlling global and local textural features through the primitive, grain, and point configuration (PGPC) texture model, a mathematical morphology-based texture model. Second, we conducted an experiment to acquire eye-movement data where participants identified the texture that was highly similar to the standard texture. Experiment data were obtained through an eye-tracker from 60 participants. The collected eye-tracking data were analyzed in terms of three metrics, including total fixation duration in each region of interest (ROI), fixation-point variance in each ROI, and fixation-transfer counts between different ROIs. Analysis results indicated the following. (1) The global and local features of a texture influenced eye-movement patterns. In particular, the texture image that was globally similar to the standard texture contained dispersed fixation points. By contrast, the texture image that was locally similar to the standard texture contained concentrated fixation points. The domination of global and local features influenced the viewers’ similarity choice. (2) The final visual-similarity selection was related to the fixation-transfer count between different ROIs, but not to the fixation time in each ROI. This research also extends the applicability of the mathematical morphology-based texture model to human visual perception.

There is a fundamental interest in the investigation of the interfacial interactions and charge migration processes between organic molecules and metallic surfaces from a theoretical standpoint. Quantum mechanical (QM) concepts of bonding are contrasted, and the vital importance of using combined QM methods to explore the nature of the interfacial interactions is established. At the one-electron level, the charge distribution and nature of bonded interactions at the AN–Cu9(100) (neutral and charged (–1)) interfaces are investigated by both the Becke (B) – Vosko (V) – Wilk (W) – Nusair (N)/DZVP density functional theory (DFT) method and the MP2/6–31+G* strategy within the conceptual framework provided by natural bond orbital (NBO) – natural atomic orbital (NAO) population analysis and Atoms-In-Molecules (AIM) theory. By this approach, the interfacial interactions are given physical definitions free of any assumptions and are visualized by using the topological features of the total electron density. A natural link between the electron density on the one side and the shapes (not energies) of the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) on the other side is clarified. The question of whether the spatial extents of the HOMO and LUMO resemble the corresponding spatial maps of the negative (charge locally concentrated) and positive (charge locally depleted) Laplacian of the total electron density in [AN–Cu9(100)]–1 is addressed.Key words: AN–Cu9(100) interfaces, NBO–NAO population, electron distribution, AIM, bonded interactions.

Recent efforts have concentrated on 3D printing for use not only in creating conceptual models but functional end-use products as well and the expiration of many of the additive manufacturing process patents of the 1980s has led to lower cost systems in general. The freedom of 3D printing along with the change in economics is leading to the democratization of manufacturing, where products will soon be fabricated locally and with requirements specified individually by the end user. However, currently 3D printing is limited to single material fabrication and consequently can only create mechanical structures. For additively manufactured end-use products to be relevant, additional features will need to be incorporated into the complex structures in terms of electronic, electromechanical, electromagnetic and thermal composition. Recent research has been reported of embedding electronic components and electrical interconnect into 3D printed structures either by interrupting the process or by inserting the additional content after the structure has been built. However, only until recently with an investment from the presidential initiative on manufacturing � America Makes � has there been a focused research effort on technology that produces multi-functionality with enhanced 3D printing, where additional manufacturing technologies are leveraged. This presentation will describe the development and status of the Multi3D Manufacturing System underway at the University of Texas at El Paso.

Geochemical and rock magnetic studies, undertaken to determine the cause of magnetic anomalies over Cement oil field (Anadarko basin, Oklahoma), Simpson oil field (North Slope basin, Alaska), and the Wyoming‐Idaho‐Utah thrust belt, have revealed different magnetic sources developed under different sedimentologic, geochemical, and structural settings. At Cement, ferrimagnetic pyrrhotite ([Formula: see text]), typically intergrown with more abundant, nonmagnetic pyrite ([Formula: see text]), formed as a result of hydrocarbon seepage. Sulfur isotopic data indicate that sulfur in the Fe‐S minerals was probably derived from two different sources: (1) isotopically heavy, thermochemical [Formula: see text] in petroleum, and (2) isotopically light [Formula: see text] generated by sulfate‐reducing bacteria that derived metabolic energy from leaking hydrocarbons or organic compounds derived from hydrocarbons. Although pyrrhotite may make a minor contribution to the reported total magnetic field anomalies at Cement, the measured anomalies are probably mostly caused by man‐made features such as buried well casings and pipelines. Magnetite, found in well cuttings from Cement and previously considered the source of the anomalies, is contamination from drilling. At Simpson, ferrimagnetic greigite ([Formula: see text]) is concentrated locally in Upper Cretaceous beds. A preliminary geochemical study reveals a complicated picture in which early diagenetic chemical and mineralogic changes are variably overprinted by later epigenetic alterations, perhaps related to hydrocarbon seepage. The greigite probably formed at different times from sulfate reduction by bacteria that used either organic compounds derived from hydrocarbons or detrital organic matter, or both, as food sources. Magnetic‐property studies suggest the natural remanent magnetization of greigite‐bearing rocks may contribute to the magnetic anomalies. In the thrust belt, the Middle Jurassic Preuss Sandstone has magnetizations as much as 0.76 A/m (average 0.14 A/m) west of the Absaroka fault where aeromagnetic anomalies locally correspond to exposures of the Preuss and much lower magnetizations (average [Formula: see text]) east of the Absaroka fault. The magnetization is carried by rounded titanium‐bearing detrital magnetite, commonly concentrated along heavy‐mineral laminations. Carbon isotopic compositions of calcite cement (−2.4 to +1.5 per mil) reflect an absence of organic carbon in the calcite and thus suggest that hydrocarbon had no role in the preservation of the detrital magnetite. Our results show that abiologic and biologic mechanisms can generate different magnetic sulfide minerals in zones of sulfidic hydrocarbon seepage. More commonly, sulfidic seepage could either diminish magnetization by replacement of detrital magnetic minerals with nonmagnetic sulfide minerals, or it would have no effect on magnetization if such detrital minerals were originally absent. An important negative result is the absence of abundant secondary (diagenetic) magnetite in the seepage environments. Although secondary magnetite occurs in some biodegraded crude oils, concentrations of such magnetite capable of producing aeromagnetic anomalies have not been documented.

AbstractGold-bearing sandstone and conglomerate near the base of the Proterozoic Mporokoso Group were deposited in a braided river system. The detrital sand grade material is mainly of quartz, sericite and haematite, and the pebbles are of vein-quartz, chert, silicic volcanics, quartzose metasediment and jaspilite. The basement rocks presently exposed in the basement are silicic igneous rocks and quartzose metasediments.The petrography of the fluvial sediments suggests that silica and, to a lesser extent, iron oxide were mobile both in the source-area and in the braided river system. Evidence for silica-mobility includes jaspilite pebbles with spherulites and glaebules of chalcedony, abundant vein-quartz pebbles, intra-basinal sandstone pebbles, and the silicification of volcanic pebbles. The detrital haematite in the fluvial sandstone forms pseudomorphs after magmatic magnetite. Authigenic iron oxide occurs in several forms which suggest that iron oxide was mobile in the source-area and in the fluvial sediments. Uranium is locally abundant in basement and sedimentary rocks, cassiterite is a common heavy mineral in the fluvial sediments, and fluorite has been found in the basement.These features may be explained by intense weathering which mobilized both silica and iron. The silica was concentrated near the surface to form silcretes in the basement and later in the overlying fluvial sediments. Hydrothermal convection cells driven by the granites may have carried silica, iron, tin, fluorine and uranium towards the surface before and during the erosion of the igneous basement.

In the last decade, research has focused on 3D printing for not only creating conceptual models but functional end-use products as well. As patents for 3D printing expire, new low cost desktop systems are being adopted more widely. This trend is leading to products being fabricated locally and improving supply chain logistics. However, currently low cost 3D printing is limited in the number of materials used simultaneously in fabrication and consequently is confined to fabricating enclosures and conceptual models. For additively manufactured end-use products to be useful, supplementary features and functionalities will need to be incorporated in to the final structures in terms of electronic, electromechanical, electromagnetic, thermodynamic, and optical content. The University of Texas at El Paso has recently been reporting on embedding electronic components and electrical interconnect into 3D printed structures either by interrupting the process or by inserting the additional content after the structure has been built. However, only until recently and with an investment from the presidential initiative on Additive Manufacturing “America Makes” has there been a concentrated research focus on developing technology that produces multi-functionality. This presentation will describe a project in which copper wires were used to supply a short burst of energy at high voltages in order to activate electro-propulsion. Pulsed Plasma Thursters provided by Busek were demonstrated where one joule of energy was supplied at 2000 volts in order to ablate the thruster in a vacuum and provide precise micro-newton-levels of force - as required for attitude control in small and nano satellites.

Abstract. The newly developed land surface scheme SURFEX (Surface Externalisée) is implemented into a limited area numerical weather prediction model running operationally in a number of countries of the ALADIN and HIRLAM consortia. The primary question addressed is the ability of SURFEX to be used as a new land surface scheme and thus assessing its potential use in an operational configuration instead of the original ISBA (Interactions between Soil, Biosphere, and Atmosphere) scheme. The results show that the introduction of SURFEX either gives improvements or neutral impact on the 2 m temperature, 2 m relative humidity, and 10 m wind. However, it seems that SURFEX has a tendency to produce higher maximum temperatures at high elevation stations during winter daytime which degrades the scores. In addition, surface radiative and energy fluxes improve compared to observations from the Cabauw tower. The results also show that promising improvements with a demonstrated positive impact are achieved by introducing the Town Energy Balance (TEB) scheme. It was found that the use of SURFEX has a neutral impact on the precipitation scores. However, the implementation of TEB within SURFEX for a high resolution run tends to cause rainfall to be locally concentrated and the total accumulated precipitation decreases obviously during the summer. One of the novel features developed in SURFEX is the availability of a more advanced surface data assimilation using the Extended Kalman Filter. The results over Belgium show that the forecast scores are similar between the Extended Kalman Filter and the classical Optimal Interpolation scheme. Finally, concerning the upper air scores, the introduction of SURFEX either gives improvement or neutral impact in the free atmosphere.

As a result of archeological research conducted on prehistoric and protohistoric periods in Anatolia a limited number of ceramic kilns were found. Therefore, two kilns, which have been found during the 2003 excavation season in Saraga Hoyuk and which belong to MBA II, are of great importance because they provide information regarding the ceramic production technology in the 2nd millennium B.C. One of these kilns is of big (Kiln 1) and the other is of small (Kiln 2) size. The both kilns show the similar work systems but both of them show same different features as the typologically. The kilns consist two chambers, in which the combustion and firing chambers. The kilns have heat transmission duct for the transfering of heat between combustion and firing chambers. Kiln 1 was used for firing of big size vessels and Kiln 2 for small size vessels. A few Middle Bronze Age pottery kiln were found in Southeast Anatolia and culturally related neighboring regions. Although, when we look Bronze and before age pottery kilns, we can say no radical shift has been empirically observed in the pottery firing techniques in the region. Kilns of Saraga Hoyuk proved that grooved rim ceramic group found along the Euphrates Valley has been produced locally at Saraga Hoyuk. The Middle Bronze Age level of Şaraga Höyük yielded material evidence for all stages of ceramic production at the site, including rotary stone, lumps of unbaked clay, pottery kilns of small and large sizes, scatters of ceramic wasters concentrated around the kilns, as well as intact ceramic vessels found in situ in the kilns.

In this paper we consider the propagation of acoustic waves on top of an inviscid steady flow along a curved hollow or annular duct with hard or lined walls. The curvature of the duct centreline (which is not restricted to being small) and the wall radii vary slowly along the duct, allowing application of an asymptotic multiple-scales analysis. The modal wavenumbers and mode shapes are determined locally as modes of a torus with the same local curvature, while the amplitude of the modes evolves as the mode propagates along the duct. The duct modes are found explicitly at each axial location using a pseudospectral numerical method.Unlike the case of a straight duct carrying uniform flow, there is a fundamental asymmetry between upstream and downstream propagating modes, with some mode shapes tending to be concentrated on either the inside or outside of the bend depending on the direction of propagation, curvature and steady-flow Mach number. The interaction between the presence of wall lining and curvature is also significant; for instance, in a representative case it is found that the curvature causes the first few acoustic modes to be more heavily damped by the duct boundary than would be expected for a straight duct.Using ray theory, we suggest explanations of these features. For the lowest azimuthal-order modes, three distinct regimes are found in which the modes are localized in different parts of the duct cross-section. This phenomenon is explained by a balance between whispering-gallery effects along the duct and refraction by the steady flow. At the opposite extreme, strongly spinning modes are investigated, and are seen to be due to a different whispering-gallery effect across the duct cross-section.

Abstract We analyze the structure and evolution of ribbons from the M7.3 SOL2014-04-18T13 flare using ultraviolet images from the Interface Region Imaging Spectrograph and the Solar Dynamics Observatory (SDO)/Atmospheric Imaging Assembly (AIA), magnetic data from the SDO/Helioseismic and Magnetic Imager, hard X-ray (HXR) images from the Reuven Ramaty High Energy Solar Spectroscopic Imager, and light curves from the Fermi/Gamma-ray Burst Monitor, in order to infer properties of coronal magnetic reconnection. As the event progresses, two flare ribbons spread away from the magnetic polarity inversion line. The width of the newly brightened front along the extension of the ribbon is highly intermittent in both space and time, presumably reflecting nonuniformities in the structure and/or dynamics of the flare current sheet. Furthermore, the ribbon width grows most rapidly in regions exhibiting concentrated nonthermal HXR emission, with sharp increases slightly preceding the HXR bursts. The light curve of the ultraviolet emission matches the HXR light curve at photon energies above 25 keV. In other regions the ribbon-width evolution and light curves do not temporally correlate with the HXR emission. This indicates that the production of nonthermal electrons is highly nonuniform within the flare current sheet. Our results suggest a strong connection between the production of nonthermal electrons and the locally enhanced perpendicular extent of flare ribbon fronts, which in turn reflects the inhomogeneous structure and/or reconnection dynamics of the current sheet. Despite this variability, the ribbon fronts remain nearly continuous, quasi-one-dimensional features. Thus, although the reconnecting coronal current sheets are highly structured, they remain quasi-two-dimensional and the magnetic energy release occurs systematically, rather than stochastically, through the volume of the reconnecting magnetic flux.

The work is devoted to solving the scientific and practical problem of automating the heart’s electrical axis calculation to improve the quality of morphological analysis of biomedical signals with locally concentrated features in cardiological decision support systems, which in turn reduces the likelihood of medical errors. The work shows that existing methods for in the determining the electrical axis of the heart require morphological analysis of an electrocardiogram. The method is based on determining the integral signal in the frontal plane from all limb leads, taking into account the lead angle in the hexaxial reference system. In graphic form in polar coordinates, the integral electrocardiological signal is a figure, predominantly elongated along the axis, the direction’n of which corresponds to the heart’s electrical axis. The position of the heart’s electrical axis is calculated as the angle between the axis of standard lead I and the vector, the end of which is at the center of mass of the locus of the points the farthest away from the reference point. Cluster analysis is used to find the most distant points from the reference point. The proposed method for of calculating the heart’s electrical axis makes it possible not to carry out a preliminary morphological analysis of an electrocardiogram. To implement the method proposed in the article, a program was written in the Matlab language, which is connected as a dynamic link library to the cardiological decision support system “TREDEX telephone” operating as part of the medical diagnostic complex “TREDEX” manufactured by “Company TREDEX” LLC, Kharkiv. Verification of the results was carried out using a database of electrocardiograms, which were recorded using a transtelephone digital 12-channel electrocardiological complex “Telecard”, which is part of the medical diagnostic complex “TREDEX”, and deciphered by cardiologists of the communal non-profit enterprise of the Kharkiv Regional Council “Center for Emergency Medical aid and disaster medicine”. Comparison of the results of calculating the heart’s electrical axis according to electrocardiograms by a doctor and automatically using the proposed method showed that in the overwhelming majority of cases the decisions made coincide. At the same time, cardiologists make mistakes, and errors are made during automatic calculation using the proposed method. The paper explains the reasons for these errors.

Research on audio-based music retrieval has primarily concentrated on refining audio features to improve search quality. However, much less work has been done on improving the time efficiency of music audio searches. Representing music audio documents in an indexable format provides a mechanism for achieving efficiency. To address this issue, in this work Exact Locality Sensitive Mapping (ELSM) is suggested to join the concatenated feature sets and soft hash values. On this basis we propose audio-based music indexing techniques, ELSM and Soft Locality Sensitive Hash (SoftLSH) using an optimized Feature Union (FU) set of extracted audio features. Two contributions are made here. First, the principle of similarity-invariance is applied in summarizing audio feature sequences and utilized in training semantic audio representations based on regression. Second, soft hash values are pre-calculated to help locate the searching range more accurately and improve collision probability among features similar to each other. Our algorithms are implemented in a demonstration system to show how to retrieve and evaluate multi-version audio documents. Experimental evaluation over a real "multi-version" audio dataset confirms the practicality of ELSM and SoftLSH with FU and proves that our algorithms are effective for both multi-version detection (online query, one-query vs. multi-object) and same content detection (batch queries, multi-queries vs. one-object).

We consider the codimension-three phenomenon of homoclinic bifurcations of flows containing a pair of orbits homoclinic to a saddle point whose principal eigenvalues are in resonance. We concentrate upon the simplest possible configuration, the so-called "figure-of-eight," and reduce the dynamics near the homoclinic connections to those on a two-dimensional locally invariant centre manifold. The ensuing resonant gluing bifurcations exhibit features of both gluing bifurcations and resonant homoclinic bifurcations. Under certain twist conditions, the bifurcation structure is extremely rich, although describing zero-entropy flows. The analysis carefully exploits the topology of the orbits, the centre manifold and the parameter space.

Secured authentication system is one of the most challenging tasks focused now-a-days by many researchers and greatly achieved by means of face detection technique. Face image recognition is currently realized by Adaptive singular value decomposition in two-dimensional discrete Fourier domain (ASVDF). The recognition systems ability enhancement is attained for face images recognition by side light influence reduction on a color face image for inadequate light. The prevailing researches does not focuses the following points: No correct output during face recognition process, Face spoofing is not concentrated thereby face recognition may effect in imprecise result, Optimal feature extraction. Optimized Face Recognition System with Illumination and Rotation Consideration (OFRS-IRC) is one of the promising solutions for mitigating all those issues. Various methods are presented for ensuring accurate face recognition. Additive White Gaussian Noise removal technique is utilized for eliminating noise when the image is captured through sensor devices. Illuminate invariant features and locality preserving projection approach is exploited for segmented image recognition. As a final step, Fuzzy neural network is deployed for precise prediction on the basis of locality preserving projection approach results. MATLAB simulation tool is exploited for evaluating this research, where improved performance are attained by proposed method than prevailing methods. The proposed method shows 7.42% better detection rate than the existing work.

Memory is becoming one of the major power consumers in computing systems. Therefore, energy efficient memory management is essential. Modern memory systems employ sleep states for energy saving. To utilize this feature, existing research activities have concentrated on increasing spatial locality to deactivate as many blocks as possible. However, they did not count the unexpected activation of memory blocks due to cache eviction of deactivated tasks. In this paper, we suggest a software-based power state management scheme for memory, which exploits temporal locality to relieve the energy loss from the unexpected activation of memory blocks from cache eviction. The suggested scheme SW-NAP makes a memory block remain deactivated during a certain tick, which has no cache miss over the block. The evaluation shows that SW-NAP is 50% better than PAVM, which is an existing software scheme, and worse than PMU, which is another approach based on the specialized hardware by 20%. We also suggest task scheduling policies that increase the effectiveness of SW-NAP and they saved up to 7% additional energy.

Foreign policy often creates geographically concentrated domestic benefits. A prominent example is the tying of development aid to purchases from the donor country. This feature of aid highlights the utility in examining foreign policy as an instance of pork-barrel politics. Considering tied aid in terms of legislators’ incentives to provide constituent benefits, we argue that people will support an increase in foreign aid spending more when it would promote local economic activity, while opposing aid cuts more when reduced local economic output would result. Crucially, we also expect that people will support their state’s US senator more when informed that the senator attempted to secure (or retain) locally beneficial funds. We find support for our expectations in a novel survey experiment of US citizens. Our results suggest that legislators’ electoral incentives, and consequential local spending, can help explain the adoption of foreign policies despite national-level public disapproval.

The Ainslie Detachment occurs near the base of the Carboniferous Windsor Group, forming a regional flat-lying extensional fault distributed across 10 000 km2. New mapping has delineated the structure through southwestern Cape Breton Island and into central Nova Scotia. Shearing is concentrated at the top of the basal Macumber limestone along its contact with overlying evaporites and younger allochthonous units. The highly contrasting rheologies of the formations created an anisotropic zone of weakness which acted as an upper crustal stress guide, stratigraphically controlling the trajectory of the detachment through the basin. The detachment is characterized by an approximately 3–10 m thick calc-mylonite zone, with an intense planar fabric featuring alternating very fine grained shear planes and coarser annealed layers. Coarser layers are boudinaged into pinch and swell structures, locally producing segmented augen. Highly strained intraclasts, ooids, and peloids, recrystallized carbonate boudins, and carbonate vein segments are included in the calc-mylonite as semirigid inclusions and rotated porphyroclasts. Thick zones of fault breccia straddle portions of the detachment and overprint the mylonite, demonstrating an evolution to brittle conditions during progressive shear. Listric faults in the hanging wall of the detachment feature a ramp and flat geometry, with an upper detachment occurring along the upper contact of the Windsor Group with the overlying Namurian Mabou Group. Locally up to 2 km of the stratigraphic succession has been removed, with faults cutting downsection in a westerly direction producing rollover in the hanging wall.

Oceanographic features, such as eddies and fronts, enhance and concentrate productivity, generating high-quality patches that dispersive marine larvae may encounter in the plankton. Although broad-scale movement of larvae associated with these features can be captured in biophysical models, direct evidence of processes influencing survival within them, and subsequent effects on population replenishment, are unknown. We sequentially sampled cohorts of coral reef fishes in the plankton and nearshore juvenile habitats in the Straits of Florida and used otolith microstructure analysis to compare growth and size-at-age of larvae collected inside and outside of mesoscale eddies to those that survived to settlement. Larval habitat altered patterns of growth and selective mortality: Thalassoma bifasciatum and Cryptotomus roseus that encountered eddies in the plankton grew faster than larvae outside of eddies and likely experienced higher survival to settlement. During warm periods, T. bifasciatum residing outside of eddies in the oligotrophic Florida Current experienced high mortality and only the slowest growers survived early larval life. Such slow growth is advantageous in nutrient poor habitats when warm temperatures increase metabolic demands but is insufficient for survival beyond the larval stage because only fast-growing larvae successfully settled to reefs. Because larvae arriving to the Straits of Florida from distant sources must spend long periods of time outside of eddies, our results indicate that they have a survival disadvantage. High productivity features such as eddies not only enhance the survival of pelagic larvae, but also potentially increase the contribution of locally spawned larvae to reef populations.

В 2021 году А.А. Драгуновым при помощи системно-геодинамического дешифрирования были выявлены Восточно-Оренбургский и Западно-Оренбургский геодинамически активные очаги генерации углеводородов Оренбургского нефтегазоконденсатного месторождения. Было предположено, что ряд малых залежей юго-запада Оренбургской области также получают от них подпитку. Целью представленной работы являлась попытка проследить вышеуказанные очаги генерации углеводородов в фундаменте и осадочном чехле на основе переинтерпретации временных разрезов региональных сейсмических профилей. Методы работы. Выделение тектонических нарушений проводилось вручную с применением авторских методических приемов приближений и последовательной детализации. После чего выполнялось системное обобщение и анализ полученных результатов в свете перспектив нефтегазоносности юго-запада Оренбургской области. Результаты работы. В результате работ было рассмотрено глубинное строение очагов, отмечены сейсмогеологические особенности их обнаружения. В местах картирования очагов генерации на временных разрезах зафиксированы неотектонические разломы «цветкового» типа, хаотическая вертикально направленная локально усиленная сейсмическая запись под ними ниже отражающего горизонта, отождествляемого с породами фундамента. Прослежена связь глубинных разломов и связанных с ними новейших оперяющих разломов с солянокупольными структурами кунгурского возраста. По результатам комплексного геологического анализа структурных построений выявлена схематическая сеть неотектонических разломов фундамента, судя по которой, Оренбургское нефтегазоконденсатное месторождение и другие, более мелкие месторождения углеводородов и выявленные сейсморазведочными работами структуры юго-запада Оренбургской области имеют закономерное распределение внутри крупной радиально-концентрической структуры диаметром около 180 км. Данная структура, вероятно, представляет собой зону разуплотнения в фундаменте, в пределах которой в осадочном чехле образовались перспективные в плане нефтегазоносности структуры. Уникальное и самое крупное в пределах юго-запада Оренбургской области Оренбургское месторождение находится в центре макроструктуры, являясь, возможно, результатом работы главных очагов генерации УВ в фундаменте. Вдоль радиальных и концентрических разломов сосредоточены более мелкие месторождения углеводородов. Кроме того, Оренбургское месторождение приурочено к зоне наложения двух концентров, что, возможно, является значительным фактором при обнаружении крупных месторождений. В качестве выводов даны рекомендации для дальнейших исследований и поиска возможных геодинамически активных очагов генерации углеводородов в пределах Русской платформы In 2021, A.A. Dragunov, using system-geodynamic decoding, identified the East-Orenburg and West-Orenburg geodynamically active centers of hydrocarbon generation of the Orenburg oil and gas condensate field. It was assumed that a number of small deposits in the south-west of the Orenburg region also receive recharge from them. The aim of the presented work was an attempt to trace the above-mentioned sources of hydrocarbon generation in the foundation and sedimentary cover on the basis of reinterpretation of time sections of regional seismic profiles. Methods. The selection of tectonic disturbances was carried out manually using the author's methodological techniques of approximations and sequential detailing. After that, a systematic generalization and analysis of the results obtained was carried out in the light of the prospects for oil and gas potential of the south-west of the Orenburg region. Results. As a result of the work, the deep structure of the foci was considered, the seismogeological features of their detection were noted. Neotectonic faults of the "flower" type, chaotic vertically directed locally enhanced seismic recording under them below the reflecting horizon identified with the basement rocks were recorded in the places of mapping the generation centers on time sections. The connection of deep faults and the newest feathering faults associated with them with salt-dome structures of the Kungur age is traced. According to the results of a comprehensive geological analysis of structural structures, a schematic network of neotectonic basement faults has been identified, judging by which the Orenburg oil and gas condensate field and other smaller hydrocarbon deposits and the structures identified by seismic surveys in the southwest of the Orenburg region have a regular distribution within a large radial-concentric structure with a diameter of about 180 km. This structure probably represents a zone of decompression in the foundation, within which promising structures in terms of oil and gas potential were formed in the sedimentary cover. The Orenburg deposit, which is unique and the largest within the south-west of the Orenburg Region, is located in the center of the macrostructure, possibly being the result of the work of the main centers of HC generation in the foundation. Smaller hydrocarbon deposits are concentrated along the radial and concentric faults. In addition, the Orenburg field is confined to the zone of overlap of two concenters, which is probably a significant factor in the discovery of large deposits. As conclusions, recommendations are given for further research and search for possible geodynamically active centers of hydrocarbon generation within the Russian platform.

In this paper, the effect of gain or loss on the dynamics of rogue waves is investigated by using the complex Ginzburg-Landau equation as a framework. Several external energy input mechanisms are studied, namely, constant background or compact Gaussian gains and a ‘rogue gain’ localized in space and time. For linear background gain, the rogue wave does not decay back to the mean level but evolves into peaks with growing amplitude. However, if such gain is concentrated locally, a pinned mode with constant amplitude could replace the time transient rogue wave and become a sustained feature. By restricting such spatially localized gain to be effective only for a finite time interval, a ‘rogue-wave-like’ mode can be recovered. On the other hand, if the dissipation is enhanced in the localized region, the formation of rogue wave can be suppressed. Finally, the effects of linear and cubic gain are compared. If the strength of the cubic gain is large enough, the rogue wave may grow indefinitely (‘blow up’), whereas the solution under a linear gain is always finite. In conclusion, the generation and dynamics of rogue waves critically depend on the precise forms of the external gain or loss.

Information granules and ensuing Granular Computing offer interesting opportunities to endow processing with an important facet of human-centricity. This facet implies that the underlying processing supports non-numeric data inherently associated with the variable perception of humans. Systems that commonly become distributed and hierarchical, managing granular information in hierarchical and distributed architectures, is of growing interest, especially when invoking mechanisms of knowledge generation and knowledge sharing. The outstanding feature of human centricity of Granular Computing along with essential fuzzy set-based constructs constitutes the crux of this study. The author elaborates on some new directions of knowledge elicitation and quantification realized in the setting of fuzzy sets. With this regard, the paper concentrates on knowledge-based clustering. It is also emphasized that collaboration and reconciliation of locally available knowledge give rise to the concept of higher type information granules. Other interesting directions enhancing human centricity of computing with fuzzy sets deals with non-numeric semi-qualitative characterization of information granules, as well as inherent evolving capabilities of associated human-centric systems. The author discusses a suite of algorithms facilitating a qualitative assessment of fuzzy sets, formulates a series of associated optimization tasks guided by well-formulated performance indexes, and discusses the underlying essence of resulting solutions.

Abstract. Gas-phase elemental mercury (Hg°) was measured aboard the NASA DC-8 aircraft during the Intercontinental Chemical Transport Experiment Phase B (INTEX-B) campaign in spring 2006. Flights were conducted around Mexico City and on two subsequent deployments over the North Pacific based out of Honolulu, Hawaii and Anchorage, Alaska. Data obtained from 0.15–12 km altitude showed that Hg° exhibited a relatively constant vertical profile centered around 100 ppqv. Highly concentrated pollution plumes emanating from the Mexico City urban agglomeration revealed that mixing ratios of Hg° as large as 500 ppqv were related to combustion tracers such as CO, but not SO2 which is presumably released locally from coal burning, refineries, and volcanoes. Our analysis of Mexico City plumes indicated that widespread multi-source urban/industrial emissions may have a more important influence on Hg° than specific point sources. Over the Pacific, correlations with CO, CO2, CH4, and C2Cl4 were diffuse overall, but recognizable on flights out of Anchorage and Honolulu. In distinct plumes originating from the Asian continent the Hg°- CO relationship yielded an average value of ~0.56 ppqv/ppbv, in good agreement with previous findings. A prominent feature of the INTEX-B dataset was frequent total depletion of Hg° in the upper troposphere when stratospherically influenced air was encountered. Ozone data obtained with the differential absorption lidar (DIAL) showed that the stratospheric impact on the tropospheric column was a common and pervasive feature on all flights out of Honolulu and Anchorage. We propose that this is likely a major factor driving large-scale seasonality in Hg° mixing ratios, especially at mid-latitudes, and an important process that should be incorporated into global chemical transport models.

<p>Most recent couple of years a few new systems administration locales wound up plainly famous (WhatsApp, Google Plus, Instagram), the utilization base developed significantly, and Facebook purchased over some of its opposition. The development of online networking alongside the fast development of advanced mobile phone use has likewise had an incredible effect on different features of our lives. This period additionally observed an extraordinary measure of overviews being led on the development of SNS, how individuals and organizations utilize them, and what are the effects caused by this media. In this paper, we introduce and break down the study comes about, and the effect it has caused on the organizations and society on the loose. We likewise concentrate on a portion of the particular sections of the general public while breaking down the effect. Further, we likewise have talked about the eventual fate of long range informal communication, how the advantages can be used for the improvement of the group, including training field, and furthermore the significance of taking essential care in order to keep away from the genuine negative effects of SNS. </p>

Abstract. The deep chlorophyll maximum (DCM) is a well-known feature of the global ocean. However, its description and the study of its formation are a challenge, especially in the peculiar environment that is the Black Sea. The retrieval of chlorophyll a (chl a) from fluorescence (Fluo) profiles recorded by Biogeochemical Argo (BGC-Argo) floats is not trivial in the Black Sea, due to the very high content of coloured dissolved organic matter (CDOM) which contributes to the fluorescence signal and produces an apparent increase in the chl a concentration with depth. Here, we revised Fluo correction protocols for the Black Sea context using co-located in situ high-performance liquid chromatography (HPLC) and BGC-Argo measurements. The processed set of chl a data (2014–2019) is then used to provide a systematic description of the seasonal DCM dynamics in the Black Sea and to explore different hypotheses concerning the mechanisms underlying its development. Our results show that the corrections applied to the chl a profiles are consistent with HPLC data. In the Black Sea, the DCM begins to form in March, throughout the basin, at a density level set by the previous winter mixed layer. During a first phase (April–May), the DCM remains attached to this particular layer. The spatial homogeneity of this feature suggests a hysteresis mechanism, i.e. that the DCM structure locally influences environmental conditions rather than adapting instantaneously to external factors. In a second phase (July–September), the DCM migrates upward, where there is higher irradiance, which suggests the interplay of biotic factors. Overall, the DCM concentrates around 45 % to 65 % of the total chlorophyll content within a 10 m layer centred around a depth of 30 to 40 m, which stresses the importance of considering DCM dynamics when evaluating phytoplankton productivity at basin scale.

Abstract. The Baltic Sea region is very sensitive to climate change; it is a region with spatially varying climate and diverse ecosystems, but it is also under pressure due to a high population in large parts of the area. Climate change impacts could easily exacerbate other anthropogenic stressors such as biodiversity stress from society and eutrophication of the Baltic Sea considerably. Therefore, there has been a focus on estimations of future climate change and its impacts in recent research. In this overview paper, we will concentrate on a presentation of recent climate projections from 12.5 km horizontal resolution atmosphere-only regional climate models from Coordinated Regional Climate Downscaling Experiment – European domain (EURO-CORDEX). Comparison will also be done with corresponding prior results as well as with coupled atmosphere–ocean regional climate models. The recent regional climate model projections strengthen the conclusions from previous assessments. This includes a strong warming, in particular in the north in winter. Precipitation is projected to increase in the whole region apart from the southern half during summer. Consequently, the new results lend more credibility to estimates of uncertainties and robust features of future climate change. Furthermore, the larger number of scenarios gives opportunities to better address impacts of mitigation measures. In simulations with a coupled atmosphere–ocean model, the climate change signal is locally modified relative to the corresponding stand-alone atmosphere regional climate model. Differences are largest in areas where the coupled system arrives at different sea-surface temperatures and sea-ice conditions.

Exquisitely preserved limb elements of Captorhinus aguti from the Lower Permian locality of Richards Spur, Oklahoma, form an excellent basis for analysing the step cycle of the hind limb of basal amniotes. An articulated composite hind limb skeleton is moved through the step cycle. These movements are constrained by the intrinsic skeletal anatomy and data from fossilized footprints attributed to Palaeozoic amniotes. Two well-defined hinge joints are evident: a distal tarsometatarsal joint, and a mesotarsal joint between the calcaneum–astragalus–centrale unit and distal tarsals. A strict homology between the latter and mesotarsal joint in lepidosaurs is uncertain. The conspicuous size disparity between the distal end of the tibia and the much larger tibial facet of the astragalus, a widespread feature of archaic amniotes, permits considerable movement between the distal end of the tibia and astragalus during the stance phase. Differential dorsoflexion, concentrated at the preaxial side of the mesotarsal joint, allows the pes to remain stationary (rather than slide laterally) on the substrate as the femur is retracted and the tarsus shifts from an anterior to lateral orientation. The distal end of the femur describes an arc of only ~60° during the stance phase, but could rotate about 60° about its long axis, a figure comparable to that recorded for living lizards.

The features of modern placement of the trade establishments are analysed in the Lviv region. The main factors that led to the formation of the trade establishment in a particular locality or region are determined. These factors include economic and geographic, demographic and resettlements, social and other factors (geographical, transportation, neighbourhood location etc.). The basic criteria for grouping of cities are defined by the level of retail development. The main criteria for grouping of cities by the level of retail development are: the number of modern trade establishments in Western Ukraine, classification of retailers by region covering, population quantity. Because of the influence of these criteria, there are six groups of location by the level of trade networks development. There are very high, high, above average, average, below average and low levels. We highlight six main groups and form next following key trends. The biggest attention is given to the regional centres as the most development retail cities. The highest concentration of trade institutions is in Lviv region as the most economically developed. After Lviv, the largest number of establishments retailers concentrated in Volhyn and Ivano-Frankivsk region. The number of establishments of retailers mainly depends on the population size of the locations. The largest concentration is observed in regional centres, and cities such as Drohobych, Kalush, Kovel, Stryi, Truskavets and Chervonohrad. The lowest concentration of retailers is in Ternopil and Chernivtsi regions, due to the predominance of small towns. We offer the ways of optimizing retailers. Key words: trading network, region covering, international, national, regional, local retailers.

Abstract Background and Aims Hybanthus austrocaledonicus (Violaceae) is a nickel (Ni) hyperaccumulator endemic to New Caledonia. One of the specimens stored at the local herbarium had a strip of bark with a remarkably green phloem tissue attached to the sheet containing over 4 wt% Ni. This study aimed to collect field samples from the original H. austrocaledonicus locality to confirm the nature of the green ‘nickel-rich phloem’ in this taxon and to systematically assess the occurrence of Ni hyperaccumulation in H. austrocaledonicus and Hybanthus caledonicus populations. Methods X-ray fluorescence spectroscopy scanning of all collections of the genus Hybanthus (236 specimens) was undertaken at the Herbarium of New Caledonia to reveal incidences of Ni accumulation in populations of H. austrocaledonicus and H. caledonicus. In parallel, micro-analytical investigations were performed via synchrotron X-ray fluorescence microscopy (XFM) and scanning electron microscopy with X-ray microanalysis (SEM-EDS). Key Results The extensive scanning demonstrated that Ni hyperaccumulation is not a characteristic common to all populations in the endemic Hybanthus species. Synchrotron XFM revealed that Ni was exclusively concentrated in the epidermal cells of the leaf blade and petiole, conforming with the majority of (tropical) Ni hyperaccumulator plants studied to date. SEM-EDS of freeze-dried and frozen-hydrated samples revealed the presence of dense solid deposits in the phloem bundles that contained &gt;8 wt% nickel. Conclusions The occurrence of extremely Ni-rich green phloem tissues appears to be a characteristic feature of tropical Ni hyperaccumulator plants.

Abstract Ground-based and airborne Doppler radar data collected during passage of frontal rainstorms over the European Alps and Cascade Mountains of Oregon are found to exhibit characteristic cross-barrier flow and precipitation patterns. A stably stratified layer of blocked (or partially blocked) low-momentum flow below mountain-crest level is separated from strong cross-barrier flow aloft by a concentrated layer of vertical wind shear. This shear layer slopes upward toward the mountain crest and persists for several hours as the storm passes over the mountain range. This pattern is remarkably similar from case to case and from one mountain range to the other. The orographically enhanced precipitation in these cases exhibits stratiform structure, marked by a radar bright band, which often drops to a lower height (indicating locally cooler conditions) immediately adjacent to the windward mountain slopes. A terrain-induced gravity wave produces strong downslope flow and spillover of precipitation onto the lee side of the barrier. An elevated reflectivity maximum appears above the mountain crest and extends a short distance (generally 20–40 km) upstream, apparently as a result of gravity wave lifting. While baroclinically induced shear may contribute to the observed pattern, two-dimensional idealized simulations indicate that, in the presence of sufficient upstream static stability, orographic effects alone are sufficient to support development of the upward-sloping shear layer on the windward side of the barrier. Furthermore, idealized simulations show that if there is preexisting vertical shear in the incident upstream flow, this shear is strengthened by the orography and that surface friction may also enhance the strength of the shear layer. The repeatable sheared velocity pattern identified here is apparently an essential feature of cases in which stably stratified low-level flow associated with a baroclinic system impinges upon a sufficiently tall mountain range. Since the layer of orographically generated shear promotes turbulence, which has been shown to aid precipitation growth over the windward slopes, these stable flow dynamics represent a potentially important mechanism for orographic precipitation enhancement in association with the passage of frontal systems over mountainous terrain.

German pianist Clara Wieck Schumann and Italian painter Artemisia Gentileschi were both tutored by their fathers from an early age and made their mark as great European artists. Their art took them both across the continent, where they met many other famous historical persons. Their lives have not only been recorded in biographies but have also been retold in several novels, or ‘fictionalised biographies’. The fictionalised biography is an interesting hybrid genre, placed somewhat uncomfortably between historiography and the art of fiction, which permits it to disregard certain expectations raised by so-called ‘factual’ biographies (e.g. that authors should strive for ‘objectivity’ or ‘truthfulness’). The relationship between fact and fiction can thus be re-negotiated, following the author’s ideological inclinations and their imaginative closure of historiographical gaps. Beginning with some general remarks on fictionalised biographies of ‘exemplary women’, this paper then examines Janice Galloway’s Clara (2002) and Susan Vreeland’s The Passion of Artemisia (2002), focusing on the complex father-daughter relationships that Clara Wieck Schumann and Artemisia Gentileschi undoubtedly experienced, and which offered the authors ample ground for a critique of historical gender relations and hierarchies. The analyses will concentrate on the heroines’ journeys in Europe. The paper examines the ways in which the two fictional rewritings of historical women artists’ lives foreground gender aspects and make use of the narrative privileges of fictionalised biography to project contemporary feminist ideas onto historical characters and events, and explores the function of the featured European locales with regard to the protagonists’ personal development in the novels.The heroines’ ventures into foreign lands are revealed to function as an impulse towards a changing perception of their fathers as well as themselves.

A região noroeste do estado do Paraná ao longo dos últimos 50 anos vem sofrendo diversos impactos decorrentes de processos erosivos lineares, ravinas e voçorocas principalmente. A ocorrência desses processos está associada a dois fatores: o histórico de ocupação da região, bem como as características pedológicas locais, principalmente a textura dos solos e sua distribuição nas vertentes. O método adotado para o mapeamento de suscetibilidade é uma adaptação do proposto por Crepani et al. (2001). Esse autor define que a suscetibilidade de uma área é definida pela soma das vulnerabilidades dos componentes do meio físico. Para a realização do trabalho foram selecionados os atributos topográficos declividade e perfil de curvatura; na pedologia, as tipologias de solo. Os resultados foram discretizados em 5 classes: Muito baixa, baixa, média, alta e muito alta suscetibilidade. As áreas de suscetibilidade a erosão Alta e Muito alta, representam 24% do município, sendo que nessas porções se concentram 26% das erosões, o tipo de solo em conjunto com as características topográficas fazem essa área mais propicia naturalmente a ocorrência dos processos erosivos. A classe de moderada suscetibilidade a erosão representam cerca de 40% do município e 54% das feições erosivas se concentra nessa unidade.

USE OF TOPOGRAPHIC ATTRIBUTES IN THE EROSIVE SUSCEPTIBILITY MAPPING IN THE RURAL AREA OF THE MUNICIPALITY OF PARANAVAÍ – PR Abstract The northwest region of the state of Paraná over the last 50 years has suffered several impacts and consequences of linear erosives, ravines and gullies mainly. The occurrence of these processes is mainly associated with two factors: the occupation history of the region, as well as local soil characteristics, mainly the soil texture and a distribution of soils along the slopes. The methodology adopted for the mapping of susceptibility to erosion follows a line of thought developed by Crepani et al. (2001). This proposal defines that the vulnerability of an area is defined by the sum of the vulnerabilities of the components of the physical environment. For the accomplishment of the methodology were selected, to represent the geomorphology, the topographic attributes: slope, curvature plane and profile; for pedology, soil typologies were selected. The results were discretized in 5 classes, from environments less susceptible to the most susceptible. The areas of susceptibility to erosion High and Very high, summed represent 24% of the municipality, being that in these portions it concentrates 26% of the area of the erosions, once in these areas the type of soil together with the topographic characteristics make it more propitious to the occurrence of linear erosive processes.The moderate susceptibility to erosion class represent about 40% of the municipality and 54% of the area of ​​erosive features is concentrated in this unit.

Although a rare occurrence in late medieval cemeteries, vessels have been found on almost all major sites of the period, such as Novo Brdo, Trgoviste, Reljina Gradina and the churchyard of St Peter?s near Novi Pazar, the churchyard of St Nicholas? at Kursumlija, the churchyard of St Stephen?s at Milentija near Brus, Mali Zvecan, Mirijevo, Vinca. Vessels occur in different places, both on top of and in graves. Fragments of pottery and glass vessels are relatively abundant in layers of earth filling burial pits and chambers, and in those immediately overlaying burial pits or gravestones. The available data make it possible to recognize almost all functional types. The most frequently found pottery shapes are larger liquid containers - jugs and pitchers, and apparently there have also been many pots, both hearth cooking and glazed (figs. 1-3; 5-9). Recognizable among the glass vessels are bottles, usually those with long fluted necks and biconical, as well as infrequent icon lamps. The data about the vessels found buried with the deceased is much more detailed. Such finds are recorded at Macvanska Mitrovica (fig. 10/3), Brestovik (fig. 13/3), Mirijevo (fig. 4/1), Vinca (figs. 4/2; 10/4), Stragari near Kragujevac, Milentija near Brus, round the church of St Peter near Novi Pazar, at the monastery of Konculic (fig. 13/2) and the monastery of Gradac. The relatively plentiful and diverse vessels discovered at the cemeteries of medieval Trgoviste are especially illustrative (fig. 10/2, 7). The available descriptions of vessels and archaeological contexts provide a general impression about the types of vessels recorded in the cemeteries of a late medieval and early modern date in the central Balkans. Glass bottles as a rule were laid in graves, while earth-fill layers, apart from bottles, contained plentiful shards of drinking vessels. As for the bottles, two types were registered: biconical and those with long fluted necks (figs. 10; 12/1). Among the glass fragments there were parts of bottles with a ring around the neck and a ribbed body (Rippenflaschen), generally known in domestic scholarship under the term Panik type bottle (fig. 10/8). Also identifiable among the recovered glass fragments are drinking vessels of several types, beakers with small or large prunts (Nuppenbecher and Krautstrunk) and ribbed (Rippenbecher), common especially in the 15th and 16th centuries (figs. 12/1, 3, 5, 6). There are also pieces with a blue thread applied around the rim and body, similar to the examples from Stalac reproduced herein (fig. 12/3). Quite rarely found are drinking vessels of cobalt blue glass, which are mostly small, except for a few examples of up to 14 cm in height, which is also the height of the abovementioned bottles. Apart from Venice and Dubrovnik (Ragusa), glassware was imported from Hungary. The discovered pottery vessels show a greater diversity, mostly in terms of shape. In addition to liquid containers - jugs, pitchers and beakers, there occur bowls, pots and even apothecary vessels. A vast majority belong to the Serbian ware of the 14th and 15th centuries. Most are glazed, and frequently painted with spirals, bands and blotches in white, green and dark brown or decorated with simple sgrafitto patterns, such as the finds from Novo Brdo (fig. 1), St Peter?s (figs 9; 13/1, 4) and the monastery of Gradac. By far the most interesting of them is the beaker from Konculic with an openwork edge around the base (fig. 12/2), which is commonly found in glass beakers of the same period. Deserving of particular attention are three cylindrical ceramic bottles from Novo Brdo (fig. 2). The presented material allows us to recognize the central issues surrounding the occurrence of vessels in the cemeteries of the 14th to 17th century in Serbia. Given the small number of recorded cases, the presence of vessels in graves as grave goods appears to have been utterly sporadic. Being based on the processed and published results, and given the small number of systematically investigated and analyzed cemeteries, however, such a conclusion should be taken with caution. In most cases, the vessels were laid beside the head of the deceased, usually on its left, rarely on the right side, and only exceptionally next to the legs or the upper body area. On the other hand, the amount of fragments discovered in cemeteries is generally large, as shown, for example, by a cursory insight into the excavation records for the site of Novo Brdo. This discrepancy is surprising and makes us think over the character of the finds, but we shall not get closer to an answer until we have detailed context analyses done and the material systematized and statistically processed. When it comes to shapes, liquid containers obviously predominated - glass bottles and ceramic pitchers, followed by glass and ceramic drinking vessels, while ceramic pots and bowls occurred in graves only rarely. The vessels are mostly small. The glass bottles are between 14 and 15 cm in height on average, except the specimen from Mali Zvecan, which is more than twice as high (36 cm). The cups show similar heights, between 10 and 16 cm. The ceramic pitchers and pots are also small, with a height usually not exceeding 16 cm. Judging by the available data, it appears that shards of larger vessels were found on top of graves (bowls, pitchers, jugs, pots), apparently brought for the memorial ceremony held at the grave, while graves usually contained small vessels, usually bottles. Apart from Serbia, the occurrence of vessels in cemeteries has also been recorded in the surrounding areas. Given their very distinctive context and character, the finds from Bosnia draw particular attention, as well as those from Croatia, where they are concentrated in the broader area of Split. This overview makes it plain that the vessels laid in graves differ little from ordinary household utensils. Moreover, all can be classified as typical of the 14th to 17th century - Venetian, Dubrovnik and Hungarian glass, and the ceramic kitchen and tableware produced locally, in Serbia. For the sake of comparison, we draw attention to similar vessels discovered on fortress, settlement and monastery sites, such as Stalac, Belgrade (fig. 14), Studenica, Mileseva, Trgoviste, Trnava near Cacak. The presented examples, combined with all previously gained insights, clearly demonstrate and corroborate the assumption that the custom of laying vessels in graves in the central Balkans was an uncommon but long-standing phenomenon. Unlike earlier periods, when it was pottery vessels that were almost exclusively placed in graves, from the 14th century on the ratio of glass to ceramic vessels, mostly bottles, pitchers and beakers, becomes virtually equal. Judging by the find-spots and other known information, in the late medieval period the custom of laying vessels in graves was confined to a few areas along the Danube, Morava, Ibar, Drina and Neretva rivers. These areas, in the hinterland of Dubrovnik, in Herzegovina, Bosnia and Serbia, are associated with major caravan routes, which is relevant in our considerations of the glass finds. As it appears from the examples from all aforementioned areas, the only difference of some significance concerns the type of glass vessels used in funeral rituals - bottles in Serbia and Croatia, and drinking vessels in Bosnia and Herzegovina. Even though this seems to give grounds to assume certain regional variation in the custom of making offerings to the dead, at this point any conclusion would be highly conjectural, especially if based only on the available archaeological data. As shown by ethnological research, the custom, also sporadic, survived in Serbia and Bulgaria until the late 19th century. The analysis of the vessels from late medieval and early modern cemeteries has revealed a number of features common to the central-Balkan region, but also some regional variation. However, given the proportion of processed specimens in the entire recovered material, the assumptions and results presented here should only be taken as preliminary. The fact that some manifestations of the custom are still obscure reduces some of the previously proposed interpretations to little more than unfounded speculation, which is fertile ground for manipulation. Apart from analyzing the archaeological material, what is needed therefore is a thorough study of other aspects of the issue, above all the phenomenon of burials topped by slabs and stecci, and funerary practices at large.

AbstractEffects of flow in the lower continental crust have often been ignored in the geomorphological literature on the growth of topography during the Quaternary. However, the ability of the lower crust to flow in response to horizontal pressure gradients, caused by lateral variations in the depth of the base of the brittle upper crust, results in two mechanisms for the growth of topography, which can occur either separately or in combination. First, an increase in the rate of erosion in a region will result in a progressive reduction in the depth of the base of the brittle layer, which will drive inflow of lower crust to beneath the region, which will increase the crustal thickness and thus the altitude of the Earth’s surface. It is important to note that this mechanism can increase the mean altitude of the Earth’s surface, not just the altitude of summits formed of erosion-resistant rock or other features that are not eroding, which will rise faster than the surrounding eroding landscape. Second, repeated cyclic surface loading by ice sheets or fluctuations in global sea-level will cause net flow from areas of relatively cool lower crust to beneath areas of warmer crust. This process will thus usually result in net flow of lower crust from beneath offshore areas to beneath land areas, thinning the crust and increasing the bathymetry offshore but adding to the crustal thickness and so uplifting the land surface onshore. Although these two processes have different mechanisms, the time scale over which both operate is governed by the time required for heat diffusion, resulting from lower-crustal flow (which is concentrated near the Moho), to affect the position of the base of the brittle layer. As a result, the uplift responses for both processes can be very similar. This means that to resolve the physical cause of uplift at any locality requires knowledge of the regional conditions before uplift began, not just evidence (such as river terrace sequences) from during the course of uplift. This study illustrates the complexities and practical difficulties that can result from these issues, using case studies of localities that have been modelled in detail. It also points out that, although the ability to carry out quantitative calculations involving lower-crustal flow is new, the idea that such flow provides a general mechanism for the growdi of topography was first suggested in the early 19th century, but was later abandoned - apparently mistakenly. An early Middle Pleistocene increase in uplift rates is widely-recognised from river terrace records, and typically marks a transition from broad valleys in areas of low relief to narrower, more deeply incised gorges. It is suggested that the isostatic response to cyclic surface loading, caused by the growth and decay of continental ice sheets and the associated sea-level fluctuations, is the main cause of this change, following the increase in scale of ice sheet development from oxygen isotope stage 22 (~0.9 Ma) onwards. The less well resolved earlier increase in uplift rates, evident in some river terrace records at ~3 Ma, is more likely to result from the isostatic response to increased rates of erosion linked to the contemporaneous deterioration in climate.

Forlev NymølleA sacrificial site from the late Pre-Roman Iron AgeForlev Nymølle is situated in a small stretch of boggy land in the northern part of the river valley of Illerup Å north of Skanderborg. During peat digging in 1947, eight small clay vessels from c. 400 AD and a few fashioned wooden items were found. However, it was not until 1960 that museum keeper Harald Andersen, Moesgard Museum, started a major and very careful excavation, which last ed until 1966. Twenry-four areas, making up 325 m2, were excavated along the southern edge of the present peat bog (fig. 1). Forlev Nymølle is still one of the largest and best documented finds off ertiliryrelated sacrificial finds in Northern Europe. The finds, which primaril y consist of potsherds, bones from domestic animals, wooden items, patches of charcoal, and – not the least – stones were concentrated in small heaps relatively close to the old lakeshore. Nine find concentrations (I-IX) were separated, excluding “concentration X”, which comprises the clay vessels found in 1947 (fig. 15).The individual find concentrations measure between 1.5 and 9 m2 , and although their contents vary greatly, they are all characterized by layers or small heaps of hand or head size stones (fig. 9, 16). Among these, a remarkable amount is light quart zite stones or flint, and their occurrence has made many scholars suggest that the throwing of stones were a central element of the sacrificial act. Potsherds and so me long ashwood sticks (fig. 6, 8, 12, 25, 26) form part of almost all stone heaps, whereas the depositing of bones from domestic animals seem to be more selective (fig. 31). Concentration I differs further by containing a simple anthropomorphic figure, which may have stood upright in the stone heap (fig. 2-3), and a bundle of flax (fig. 4). Most find concentrations seem to represent a single sacrifice, except for concentration I, which is interpreted with certainry as having been used more than once.Some heavy tree trunks foun d in the immediate viciniry of some of the find heaps are thought to have functioned as a trackway from which the sacrifices could be made.The form and appearance of the individual concentrations are thought to be the result of depositing (fig. 7) including ritual stone throwing.Most bones are intact, except for a few that are split (this is interpreted as evidence for the deliberate extraction of marrow) and are marked by fire.They were mainly found in concentration II and Ill and come chiefly from small, but harmoniously built domestic oxen. Bones from sheep and goats are also present, but only a few bones from dogs and horses and from a single hare were registered. A human bone, the fragment of a shoulder blade with cutting marks and polished edges – perhaps an amulet? – was also found.The pottery, which could be assembled to make more or less complete vessels, dates the activities to the late Pre-Roman Iron Age (fig. 5). Two sacrificial horizons may be isolated (fig. 17), one of which belongs to the time between c. 200 and 150 BC (fig. 13-1 4,19) and the other to the time between c. 100 and 50 BC (fig. l0a-b, 1la).The area does not seem to have been used during the final phase of the Pre- Roman Iron Age, from 50 to 0 BC.Among the more curious items is a wooden idol and some long ashwood sticks. The wooden idol, which lay in concentration I, was made from a forked oak branch. It has a length of 2.74 meters and a very simple form with out the obvious emphasizing of the sex, which characte rizes the idols from Braak and Wittemoor (fig. 23-24) and others. The branches make up the legs, and the upper part of these have been chopped in order to accentuate the swayed hips. The sex may be indicated by a small notch at the point of bifurcatio n (fig. 18). As both ethnographic and some prehistoric figures are decorated (fig. 20-22), the idol was carefully examined, but no traces of colour, lashing etc. were found. Pottery found with the idol dates from 200-150 BC.Ashwood sticks are a normal occurrence in Forlev, represented as it is by 17 or 18 sticks from at least seven of the nine concentrations, and they seem to play a central part in the sacrificial ceremonies. They are characterized by a systematic choice of wood type, form, fashion and method of sacrifice. All were made from ashwood, they have a length of up to two meters, and one end is always finished with a cut, cross-going, triangular part. They were made from the outermost part of the trunk , the curved, de-barked side of which makes up the outside, whereas the inside is carefully carved (fig . 25). They were often laid down in pairs as a “set” consisting of a slender and a more heavy stick. They were made for the purpose, as the axe cut s are completely fresh (fig. 26). No parallels are known, but they resemble some long plank idols found in bogs in Lower Saxony (fig. 27). The function is pure guesswork – were they percussion instruments or prinlitive figures? The sticks are accessories of both sacrificial horizons.The rest of the wooden items from Forlev are also difficult to interpret, but seem to belong to the household sphere (fig. 28). However, some – like the 2.62-cm long smoothed ashwood stick (fig. 29) and the hazelwood club (fig. 30) may have functioned as ceremonial accessories.It appears from a comparison with other comprehensive finds of fertility sacrifices, such as Hedelisker, Varbrogård, Bukkerup, and Valmose- Rislev in Denmark, Käringsjön from Western Sweden and Oberdorla in Thuringia, that this find group has several features in common. The sacrificial areas are often large and characterized by relatively long periods of use. Often each locality has many small depositing sites with pottery, bones,and carved wooden objects, which are usually thought to have been sacrificed in water. Layers or heaps of stones and different branch-work are other characteristics.It is impossible to decide whether these features express common ideas, and a closer stud of the in dividual localities seems to stress the variety, even between neighbouring and contemporary sites such as Forlev Nymølle and Hedelisker. Local traditions seem to play an important part.Fertility sacrifices could be expected to follow a certain, cyclical pattern , but it has been impossible to determine such a pattern at Forlev, where the sacrificial ceremonies are not assumed to have been very numerous either. Even if we assume that the whole lake shore was full of sacrificial offerings with the same density as concentration I-III, it would be difficult to reach a number corresponding to an annual sacrifice. As several of the separated deposits seem to represent the very same action, the activity level is reduced further. Hence, the sacrifices, which are assumed collective and made by a whole village or the inhabitants of a smaller area, should rather be linked with certain events. This assumption seems to be supported by the separation of two sacrificial horizons.Today, it is generally accepted that the religious aspect was strongly integrated into the daily life of prehistoric man, and seen in the light of our present knowledge of settlements, burial customs, etc. our knowledge of the religious manifestation s is still very limjted.That is why even today, Forlev Nymølle appears to be a unique find without any clear parallels.Jørgen LundAfdeling for ForhistoriskArkæologi Aarhus UniversitetMoesgårdGenstandstegninger: Jørgen Mührman-LundGenstandsfotos: Photolab, MoesgårdUdgravningsfotos: Harald AndersenTranslated by Annette Lerche Trolle

TamdrupRoyal residence and memorial church in a new light Tamdrup has been shrouded in a degree of mystery in recent times. The solitary church located on a moraine hill west of Horsens is visible from afar and has attracted attention for centuries. On the face of it, it resembles an ordinary parish church, but on closer examination it is found to be unusually large, and on entering one discovers that hidden beneath one roof is a three-aisled construction, which originally was a Romanesque basilica. Why was such a large church built in this particular place? What were the prevailing circumstances in the Early Middle Ages when the foundation stone was laid? The mystery of Tamdrup has been addressed and discussed before. In the 1980s and 1990s, archaeological excavations were carried out which revealed traces of a magnate’s farm or a royal residence from the Late Viking Age or Early Middle Ages located on the field to the west of the church (fig. 4), and in 1991, the book Tamdrup – Kirke og gård was published. Now, by way of metal-detector finds, new information has been added. These new finds provide several answers, but also give rise to several new questions and problems. In recent years, a considerable number of metal finds recovered by metal detector at Tamdrup have been submitted to Horsens Museum. Since 2012, 207 artefacts have been recorded, primarily coins, brooches, weights and fittings from such as harness, dating from the Late Viking Age and Early Middle Ages. Further to these, a coin hoard dating from the time of Svein Estridson was excavated in 2013. The museum has processed the submitted finds, which have been recorded and passed on for treasure trove evaluation. As resources were not available for a more detailed assessment of the artefacts, in 2014 the museum formulated a research project that received funding from the Danish Agency for Culture, enabling the finds to be examined in greater depth. The aim of the research project was to study the metal-detector finds and the excavation findings, partly through an analysis of the total finds assemblage, partly by digitalisation of the earlier excavation plans so these could be compared with each other and with the new excavation data. This was intended to lead on to a new analysis, new interpretations and a new, overall evaluation of Tamdrup’s function, role and significance in the Late Viking Age and Early Middle Ages.Old excavations – new interpretationsIn 1983, on the eastern part of the field, a trial excavation trench was laid out running north-south (d). This resulted in two trenches (a, b) and a further three trial trenches being opened up in 1984 (fig. 6). In the northern trench, a longhouse, a fence and a pit-house were discovered (fig. 8). The interpretation of the longhouse (fig. 4) still stands, in so far as we are dealing with a longhouse with curved walls. The western end of the house appears unequivocal, but there could be some doubt about its eastern end. An alternative interpretation is a 17.5 m long building (fig. 8), from which the easternmost set of roof-bearing posts are excluded. Instead, another posthole is included as the northernmost post in the gable to the east. This gives a house with regularly curved walls, though with the eastern gable (4.3 m) narrower than the western (5.3 m). North of the trench (a) containing the longhouse, a trial trench (c) was also laid out, revealing a number of features. Similarly, there were also several features in the northern part of the middle trial trench (e). A pit in trial trench c was found to contain both a fragment of a bit branch and a bronze key. There was neither time nor resources to permit the excavation of these areas in 1984, but it seems very likely that there are traces of one or more houses here (fig. 9). Here we have a potential site for a possible main dwelling house or hall. In August 1990, on the basis of an evaluation, an excavation trench (h) was opened up to the west of the 1984 excavation (fig. 7). Here, traces were found of two buildings, which lay parallel to each other, oriented east-west. These were interpreted as small auxiliary buildings associated with the same magnate’s farm as the longhouse found in the 1984 excavation. The northern building was 4 m wide and the southern building was 5.5 m. Both buildings were considered to be c. 7 m long and with an open eastern gable. The southern building had one set of internal roof-bearing posts. The excavation of the two buildings in 1990 represented the art of the possible, as no great resources were available. Aerial photos from the time show that the trial trench from the evaluation was back-filled when the excavation was completed. Today, we have a comprehensive understanding of the trial trenches and excavation trenches thanks to the digitalised plans. Here, it becomes apparent that some postholes recorded during the evaluation belong to the southernmost of the two buildings, but these were unfortunately not relocated during the actual excavation. As these postholes, accordingly, did not form part of the interpretation, it was assumed that the building was 7 m in length (fig. 10). When these postholes from the evaluation are included, a ground plan emerges that can be interpreted as the remains of a Trelleborg house (fig. 11). The original 7 m long building constitutes the western end of this characteristic house, while the remainder of the south wall was found in the trial trench. Part of the north wall is apparently missing, but the rest of the building appears so convincing that the missing postholes must be attributed to poor conditions for preservation and observation. The northeastern part of the house has not been uncovered, which means that it is not possible to say with certainty whether the house was 19 or 25 m in length, minus its buttress posts. On the basis of the excavations undertaken in 1984 and 1990, it was assumed that the site represented a magnate’s farm from the Late Viking Age. It was presumed that the excavated buildings stood furthest to the north on the toft and that the farm’s main dwelling – in the best-case scenario the royal residence – should be sought in the area to the south between the excavated buildings. Six north-south-oriented trial trenches were therefore laid out in this area (figs. 6, 7 and 13 – trial trenches o, p, q, r, s and t). The results were, according to the excavation report, disappointing: No trace was found of Harold Bluetooth’s hall. It was concluded that there were no structures and features that could be linked together to give a larger entity such as the presumed magnate’s farm. After digitalisation of the excavation plans from 1991, we now have an overview of the trial trenches to a degree that was not possible previously (fig. 13). It is clear that there is a remarkable concentration of structures in the central and northern parts of the two middle trial trenches (q, r) and in part also in the second (p) and fourth (s) trial trenches from the west, as well as in the northern parts of the two easternmost trial trenches (s, t). An actual archaeological excavation would definitely be recommended here if a corresponding intensity of structures were to be encountered in an evaluation today (anno 2016). Now that all the plans have been digitalised, it is obvious to look at the trial trenches from 1990 and 1991 together. Although some account has to be taken of uncertainties in the digitalisation, this nevertheless confirms the picture of a high density of structures, especially in the middle of the 1991 trial trenches. The collective interpretation from the 1990 and 1991 investigations is that there are strong indications of settlement in the area of the middle 1991 trial trenches. It is also definitely a possibility that these represent the remains of a longhouse, which could constitute the main dwelling house. It can therefore be concluded that it is apparently possible to confirm the interpretation of the site as a potential royal residence, even though this is still subject to some uncertainty in the absence of new excavations. The archaeologists were disappointed following the evaluation undertaken in 1991, but the overview which modern technology is able to provide means that the interpretation is now rather more encouraging. There are strong indications of the presence of a royal residence. FindsThe perception of the area by Tamdrup church gained a completely new dimension when the first metal finds recovered by metal detector arrived at Horsens Museum in the autumn of 2011. With time, as the finds were submitted, considerations of the significance and function of the locality in the Late Viking Age and Early Middle Ages were subjected to revision. The interpretation as a magnate’s farm was, of course, common knowledge, but at Horsens Museum there was an awareness that this interpretation was in some doubt following the results of the 1991 investigations. The many new finds removed any trace of this doubt while, at the same time, giving cause to attribute yet further functions to the site. Was it also a trading place or a central place in conjunction with the farm? And was it active earlier than previously assumed? The 207 metal finds comprise 52 coins (whole, hack and fragments), 34 fittings (harness, belt fittings etc.), 28 brooches (enamelled disc brooches, Urnes fibulas and bird brooches), 21 weights, 15 pieces of silver (bars, hack and casting dead heads), 12 figures (pendants, small horses), nine distaff whorls, eight bronze keys, four lead amulets, three bronze bars, two fragments of folding scales and a number of other artefacts, the most spectacular of which included a gold ring and a bronze seal ring. In dating terms, most of the finds can be assigned to the Late Viking Age and Early Middle Ages. The largest artefact group consists of the coins, of which 52 have been found – either whole or as fragments. To these can be added the coin hoard, which was excavated in 2013 (fig. 12) and which primarily consists of coins minted under Svein Estridson. The other, non-hoard coins comprise: 13 Svein Estridson (figs. 15, 16), five Otto-Adelheid, five Arabic dirhams, three Sancta Colonia, one Canute the Great, one Edward the Confessor, one Theodorich II, one Heinrich II, one Rand pfennig, one Roman denarius (with drilled hole) and nine unidentified silver coins, of which some appear however to be German and others Danish/Anglo-Saxon. Most of the single coins date from the late 10th and early 11th centuries. The next-largest category of finds from Tamdrup are the fittings, which comprise 34 items. This category does, however, cover a broad diversity of finds, of which the dominant types are belt/strap fittings of various kinds and fittings associated with horse harness (figs. 17-24). In total, ten fittings have been found by metal detector that are thought to belong to harness. In addition to these is a single example from the excavation in 1984. The majority of these fittings are interpreted as parts of curb bits, headgear and stirrups. One particularly expressive figure was found at Tamdrup: a strap fitting from a stirrup, formed in a very characteristic way and depicting the face of a Viking (fig. 20). The fitting has been fixed on the stirrup strap at the point where the sides meet. Individual stirrup strap fittings are known by the hundred from England and are considered stylistically to be Anglo-Scandinavian. The fitting from Tamdrup is dated to the 11th century and is an example of a Williams’ Class B, Type 4, East Anglian type face mount. A special category of artefacts is represented by the brooches/fibulas, and enamel brooches are most conspicuous among the finds from Tamdrup. Of the total of 28 examples, 11 are enamel brooches. The most unusual is a large enamel disc brooch of a type that probably has not been found in Denmark previously (fig. 24). Its size alone (5.1 cm in diameter) is unusual. The centre of the brooch is raised relative to the rim and furnished with a pattern of apparently detached figures. On the rim are some alternating sail-shaped triangles on a base line which forms four crown-like motifs and defines a cruciform shape. Between the crowns are suggestions of small pits that probably were filled with enamel. Parallels to this type are found in central Europe, and the one that approaches closest stylistically is a brooch from Komjatice in western Slovakia, found in a grave (fig. 25). This brooch has a more or less identical crown motif, and even though the other elements are not quite the same, the similarity is striking. It is dated to the second half of the 10th century and the first half of the 11th century. The other enamel brooches are well-known types of small Carolingian and Ottonian brooches. There are four circular enamel cross-motif brooches (fig. 26a), two stellate disc brooches with central casing (fig. 26b), one stepped brooch with a cruciform motif, one cruciform fibula with five square casings and two disc-shaped brooches. In addition to the enamel brooches there are ten examples that can definitely be identified as animal brooches. Nine of these are of bronze, while one is of silver. The motifs are birds or dragons in Nordic animal styles from the Late Viking Age, Urnes and Ringerike styles, and simpler, more naturalistic forms of bird fibulas from the Late Viking Age and Early Middle Ages. Accordingly, the date for all the animal brooches is the 11th and 12th centuries. A total of 21 weights of various shapes and forms have been found at Tamdrup: spherical, bipolar spherical, disc-shaped, conical, square and facetted in various ways. Rather more than half are of lead, with the remainder being of bronze, including a couple of examples with an iron core and a mantle of bronze (so-called ørtug weights), where the iron has exploded out through the bronze mantle. One of the bipolar spheres (fig. 28) has ornamentation in the form of small pits on its base. Weights are primarily associated with trade, where it was important to be able to weigh an agreed amount of silver. Weights were, however, also used in the metal workshops, where it was crucial to be able to weigh a particular amount of metal for a specific cast in order to achieve the correct proportions between the different metals in an alloy. Eight bronze keys have been found, all dated broadly to the Viking Age (fig. 29). Most are fragmentarily preserved pieces of relatively small keys of a very simple type that must be seen as being for caskets or small chests. Keys became relatively widespread during the course of the Viking Age. Many were of iron and a good number of bronze. Nevertheless, the number of keys found at Tamdrup is impressive. A further group of artefacts that will be briefly mentioned are the distaff whorls. This is an artefact group which appears in many places and which was exceptionally common in the Viking Age. In archaeological excavations, examples are often found in fired clay, while metal distaff whorls – most commonly of lead – are found in particular by metal detector. Nine distaff whorls have been found at Tamdrup, all of lead. The finest and absolutely most prestigious artefact is a gold ring, which was found c. 60 m southwest of house 1. The ring consists of a 2 mm wide, very thin gold band, while the fittings comprise a central casing surrounded by originally eight small circular casings. In the middle sits a red stone, presumably a garnet, mounted in five rings. In a circle around the stone are the original eight small, circular mounts, of which six are preserved. The mounts, from which the stones are missing, alternate with three small gold spheres. The edges of the mounts have fine cable ornamentation. The dating is rather uncertain and is therefore not ascribed great diagnostic value. In the treasure trove description, the ring is dated to the Late Middle Ages/Renaissance, but it could presumably also date from the Early Middle Ages as it has features reminiscent of the magnificent brooch found at Østergård, which is dated to 1050. Two other spectacular artefacts were found in the form of some small four-legged animals, probably horses, cast in bronze. These figures are known from the Slav area and have presumably had a pre-Christian, symbolic function. Common to both of them are an elongated body, long neck and very short legs. Finally, mention should be made of four lead amulets. These are of a type where, on a long strip of lead, a text has been written in runes or Latin characters. Typically, these are Christian invocations intended to protect the wearer. The lead amulets are folded together and therefore do not take up much space. They are dated to the Middle Ages (1100-1400) and will therefore not be dealt with in further detail here. What the artefacts tell usWhat do the artefacts tell us? They help to provide a dating frame for the site, they tell us something about what has taken place there, they give an indication of which social classes/strata were represented, and, finally, they give us an insight into which foreign contacts could have existed, which influences people were under and which networks they were part of. Most of the artefacts date from the period 900-1000, and this is also the dating frame for the site as a whole. There is a slight tendency for the 10th century finds to be more evenly distributed across the site than those from the 11th century, which tend to be concentrated in the eastern part. A number of the finds are associated with tangible activities, for example the weights and, especially, the distaff whorls. Others also had practical functions but are, at the same time, associated with the upper echelons of society. Of the material from Tamdrup, the latter include the harness fittings and the keys, while the many brooches/fibulas and pendants also belong to artefact groups to which people from the higher strata of society had access. Some of the harness fittings and brooches suggest links with England. The stirrup-strap fitting and the cruciform strap fitting in Anglo-Scandinavian style have clear parallels in the English archaeological record. The coins, on the other hand, point towards Germany. There are a number of German coins from the end of the 10th century and the beginning of the 11th century, but the occurrence of Otto-Adelheid pennies and other German coins is not necessarily an indication of a direct German connection. From the second half of the 11th century, Svein Estridson coins dominate, but they are primarily Danish. Other artefacts that indicate contacts with western Europe are the enamelled brooches in Carolingian-Ottonian style. A number of objects suggest some degree of trade. Here again, it is the coins and the hack silver, and also the relatively large number of lead weights, that must be considered as relatively reliable indicators of trade, at least when their number is taken into consideration. In the light of the metal-detector finds it can, in conclusion, be stated that this was a locality inhabited by people of middle to high status. Many objects are foreign or show foreign inspiration and suggest therefore that Tamdrup was part of an international network. The artefacts support the interpretation of Tamdrup as a magnate’s farm and a royal residence. ConclusionTamdrup was located high up in the landscape, withdrawn from the coast, but nevertheless with quick and easy access to Horsens Fjord. Tamdrup could be approached from the fjord via Nørrestrand and the river Hansted Å on a northern route, or by the river Bygholm Å on a southern route (fig. 33). A withdrawn loca­tion was not atypical in the Viking Age and the Early Middle Ages. At that time there were also sites directly on the coast and at the heads of fjords, where early urbanisation materialised through the establishment of the first market towns, while the king’s residences had apparently to be located in places rather less accessible by boat and ship. As withdrawn but central, regional hubs and markers between land and sea. One must imagine that Tamdrup had a high status in the 10th and 11th centuries, when the king had a residence and a wooden church there. A place of great importance, culminating in the construction of a Romanesque basilica to commemorate the Christianisation of Denmark. Tamdrup appears to have lost its significance for the monarchy shortly after the stone church was completed, which could fit with King Niels, as the last of Svein Estridson’s sons, being killed in 1134, and another branch of the royal family taking over power. At the same time as Tamdrup lost its importance, Horsens flourished as a town and became of such great importance for the Crown that both Svein Grathe and Valdemar the Great had coins minted there. Tamdrup must have been a central element of the local topography in the Viking Age, when Horsens functioned as a landing place, perhaps with seasonal trading. In the long term, Horsens came out strongest, but it must be assumed that Tamdrup had the highest status between AD 900 and 1100.Lars PaghHorsens Museum

Sacrificial Tradition and Religion during the Early Iron Age in South Scandinavia – with Special Reference to Settlement SacrificesSacrificial customs and religion during the Early Iron Age (500 BC–400 AD) has occupied archaeologists from the infancy of archaeology. Most would probably agree that the religion was primarily fertility related, originating as it was in the existing peasant society. The literature does not reflect any disagreement about the religion of the Early Iron Age being polytheistic and consequently concerned a variety of gods. However, it is still unknown how the religion was integrated in the everyday life, and under which conditions it was practiced.The research interest and the overall synthesis framework have especially addressed sacrifices in bogs and wetlands (for instance weapon sacrifices, bog bodies, deposited earthenware, anthropomorphic wooden figures, domestic animals, cauldrons, ring sacrifices, etc.). Strongly simplified, the existing consensus may be expressed in one single sentence: The overall society-related sacrificial traditions develop from being almost exclusively connected with wetland areas during the Early Iron Age (until c.400 AD) to being primarily connected with dry land after this time, cf. Fig. 1.The question is whether – based on the intense data collection over the recent decades – archaeology can or should maintain this very simple picture of the development of the sacrificial traditions and the religions during the Iron Age? Is it possible that we – rooted in for instance narrow definitions of sacrificial finds, habitual thinking, and a “delusion” consisting of the numerous well-preserved, well-documented, spectacular, and impressive finds of bog sacrifices – fail to see numerous forms of deposits, which (as opposed to the impressive finds of sacrifices in bogs) are hidden in the archaeological material?The settlements of the Iron Age have been excavated in large numbers over the recent decades, and it is the ritual finds from these localities that provide the background for this article.The ritual deposits from the settlements can be divided into two superior groups distinguished by the physical context. One comprises sacrifices made to constructions, which are characterized by being directly connected to a specific structure; the other encompasses settlement sacrifices that are to a higher degree characterized by an overriding affiliation to the settlement. The establishment of a sacrifice definition suitable for scanning the archaeological material for relevant finds is of vital importance. As the definition should not beforehand restrict the search through the material, it is important not to narrow the basis by concentrating only on the physical characteristics of the individual artefacts. The general idea behind the present presentation is that the different ritual dimensions of a society are internally connected as they function within the same overall conventions and, as a consequence, make up parts of a general mental structure, which can leave physically recognizable traces across the different ritual dimensions, cf. Fig. 2. This principal viewpoint creates a theoretical starting point for my work and the established definition of sacrificial finds: All intentionally deposited objects, which analytically show significant similarities as regards their physical appearance and/or their deposition context with other recognized ritual objects/contexts, and which are closely connected to these in time and space, should, when analysed, be considered sacrificial finds.The British religious historian, Ninian Smart, describes religion as consisting of seven thematically describing situations, which – albeit not completely unconnected – may be described individually:1) A dogmatic and philosophical dimension, comprising doctrine systems.2) A mythical and narrative dimension, comprising tales of the deities, of the creation, etc.3) An ethical and judicial dimension, comprising the consequences of the religion in relation to the shaping of the life of the individual.4) A social and institutional dimension comprising organisations and institutions that tie together the individual religious society.5) An empirical and emotional dimension comprising the individual’s experience of god and the divine.6) A ritual and practical dimension comprising prayer, sacrifices, worship, etc.7) A materiel dimension comprising architecture, art, sacred places, buildings, and iconography.As archaeologists, we have a very limited possibility of investigating the very thoughts behind the practiced religion. It is therefore natural to concentrate to a higher extent on the overall setting for it – the ritual dimension and the materiel dimension respectively. The ritual dimension and in particular its sacrificial aspect is traditionally divided into groups characterised by their significance level within the religion as such.1) The first and most “important” group consists of cult rituals. These are characterized by being calendar rites based on the myths of the religion or the history of the people, and by playing a part in the events of the year.2) The next group comprises transition rites (rite de passage), which follow the life cycle of the individual.3) The last group comprises rites of crises, which serve the purpose of averting danger, illness, etc.It is important to realize that the two first ritual groups are predictable cyclic rituals addressing the gods, the myths, and/or the people/the individual respectively. Only the third and least central group of rituals is determined by non-predictable and “not-always” occurring incidences. On this background, it becomes central to analyse, which category one is facing when one wants to assess its importance for the religion as such, in order to evaluate the primary character of the religion.In an attempt to understand the overall importance of a specific ritual practice, one cannot ignore a very complicated problem, which is to evaluate whether the sacrifices were practiced by single individuals or by a larger group of people as part of more common and society-supporting rituals. The issue of the relation between different sacrifice types and the groups causing these has been addressed repeatedly. Often, narrow physical interpretation frames as to who sacrificed what are advanced (i.e. Fig. 3). However, the question is how suitable are these very narrow and rigid interpretation models? As mentioned above, a sacrifice is defined by the intention (context) that caused it rather than by the specific physical form of the object!The above mentioned methodical and theoretical issues provide the background for the author’s investigation of the archaeological sources, in which he focused especially on the relationship between ritual actions as they are expressed in bog deposits and in burial grounds and measured them against the contemporary finds from the settle­ments.The analysis of the archaeological material is based on those find groups (sacrifices of cauldrons, magnificent chariots, humans, animals, metals, and weapons), which have traditionally been presented as a proof that society supporting and more community influenced ritual sacrifices were carried out beside the bogs.The examination of the material supports that sacrifices of cauldrons, magnificent chariots, humans, animals, and earthenware are found in both settlements and wetlands (Figs. 4-12), and that the deposits seem to follow superior ritual conventions, i.e. Fig. 2. The sacrifices were not made in fixed sacred places but in a momentary sacred context, which returns to its daily secular sphere once the rituals have been carried out. Often, the ceremony consists of a ritual cutting up of the sacrificed object, and the pars pro toto principle occurs completely integrated in connection with both burial customs, wetland sacrifice customs, and settlement sacrifice customs. Sacrifices often occur as an expression of a rite de passage connected to the structures, fields, or infrastructure of the village. However, the repeated finds of earthenware vessels, humans, and animals in both wetland areas and in the villages indicates that fertility sacrifices were made regularly as part of the cyclic agricultural world. This places the find groups in a central position when it comes to understanding the religious landscape of the Early Iron Age. In a lot of respects, the settlement finds appear as direct parallel material to the contemporary wetland-related sacrificial custom and so one must assume that major religious events also took place in the settlements, for instance when a human or a cauldron was handed over to the next world. Both the selection of sacrificial objects, the form of depositing, and the preceding ceremonial treatment seem to follow superior ritual structures applying to both funerary rites and wetland sacrifices in Iron Age society.Often, the individual settlement-related sacrificial find seems to be explained by everyday doings, as largely all sacrifice-related objects of the Early Iron Age have a natural affiliation with the settlement and the daily housekeeping. However, it is clear that if the overwhelming amount of data is made subject to a comprehensive and detailed contextual analysis, settlement related find groups and attached action patterns appear, which have direct parallels in the ritual interpretation platform of the bog context. These parallels cannot be explained by pure practical or coincidence-related explanation models!As opposed to ploughed-up Stone Age axe deposits or impressive bronze depots from the Bronze Age and gold depots from the Late Iron Age, a ploughed-up collection of either earthenware, bones, human parts, etc. are not easily explained as sacrificial deposits. However, much indicates that the sacrificial settlement deposits of the Iron Age were not placed very deeply, and so they occur in the arable soil of later times. We must therefore assume that these very settlement-related sacrificial deposits from the Early Iron Age are extremely underrepresented in the available archaeological material. In order to clarify the sacrifice traditions in the Early Iron Age settlements, it is therefore necessary to have localities, which comply with a very rarely occurring find situation. The sites must have fine preservation conditions for bone material and, equally important, thick, continuously accumulated deposits of culture layers, as these preserve the usually shallowly deposited sacrifices. Further, it would be a great advantage if the site has a high degree of settlement continuity, as under optimal conditions, the investigation should comprise the activities of several centuries on the same spot.The Aalborg area holds Early Iron Age localities, which meet all of the above-mentioned conditions – for instance the settlement mound of Nr. Tranders, from which a few results will be pointed out. Time wise, the locality covers all of the Pre-Roman Iron Age and the fist part of the Early Roman Iron Age. Around ten farm units have been excavated from the settlement, each of which can be traced across a period of several hundred years. The houses were constructed with chalk floors (cf. Fig. 13), which give optimal preservation conditions for bone material, and the culture deposits assumed a thickness of up to 2 metres. Around 150 houses were excavated at this site (cf. Fig. 14). The author systematically checked the comprehensive find material, and starting from the theoretical and methodical approach presented in this article, was able to isolate 393 sacrificial deposits – a very comprehensive material in comparison with the sacrificial wetland sites!In 279 cases, it was possible to isolate sacrifices in connection with constructions. These comprised such different items as Stone Age axes, fossils, dress pins, a bronze fibula, iron knives, iron arrowheads, a bronze ring, an iron axe, various pottery sacrifices, amber, bone stilettos, bone spearheads, a bone arrowhead, complete animal skeletons, animal skulls and jaws, various animal bones, an infant, humane skull fragments, etc. (cf. Fig. 15). Just as the sacrificed objects themselves vary, so does the sacrifice intensity in the different constructions. Thus, houses without any registered construction sacrifices occur, whereas other constructions showed up to 5-15 sacrifices. These intense sacrifice activities are mainly connected with the later settlement phases from the Late Pre-Roman and the Early Roman Iron Age.The most ordinary find groups are different animal bones, pottery, Stone Age axes, fossils, and various pointed or edged tools. It is a characteristic of the construction sacrifices that they almost never show any signs of having been burnt prior to the depositing. The fact that all finds are not comparable merely because they are related to a construction is obvious, as the find group comprises as different objects as a sea urchin and an infant! Whereas the first should probably be considered an amulet, human sacrifices are traditionally considered a far more radical and ultimate act, and thus a sacrifice concerning a wider circle than the individual household. The highly varied sacrifice material causes the traditional link between construction sacrifices and an extremely narrow celebrant group to be reassessed. The excavations at Nr. Tranders also stress the fact that the amount of registered construction sacrifices are highly dependant on the preservation conditions and context registration as well as an open mind towards ritual interpretations in a traditionally secular research setting.In 114 cases, it was possible to determine settlement sacrifices at Nr. Tranders (cf. Fig. 16). The variation between the sacrificed objects closely follows the above described construction sacrifice and bog sacrifice traditions – both as regards temporary intensity in the centuries around the birth of Christ and which objects were deposited. From a superior view, the settlement sacrifices are characterized by often having been deposited in small, independent sacrificial pits, which were merely dug down a few centimetres from the surface level of the time, and rarely more than 25 cm. This very limited deposition depth emphasizes the enormous problems and distorting factors, which are probably the reason why the settlement sacrifices are so anonymous in most Iron Age settlements. They were simply ploughed away! The dominating sacrificial animal in the settlements was the sheep, often a lamb. However, the dog, the horse, and the cow also occur frequently in the material, whereas the pig is rarely included in the finds. To judge from both settlement and structure sacrifices, the distribution of sacrificial animals seem to be a direct mirror image of the life basis of the Early Iron Age society in the Aalborg area.One ritual element in particular, however, fundamentally separates the group of settlement sacrifices from those connected to structures, namely fire. Whereas fire does not seem to be part of the ritual make-up concerning structure sacrifices, both burnt and unburnt sacrifices appear in the settlement sacrifice material (cf. Fig. 17 & 18). This condition is especially obvious when examining the deposited animal and human bones. The two maps on Fig. 19 show the finds of burnt and unburnt bone deposits respectively. On the background of these two plots (x, y, and z coordinates) the following analysis has been made: (interpolation “unburnt”)-(interpolation “burnt”), cf. Fig. 20. The analysis clearly points out that the relation between burnt and unburnt bone deposits is time related: the burnt deposits were made in the time before the birth of Christ, whereas the unburnt deposits were made during the following centuries. If this is related to the contemporary development of the grave custom in North Jutland, it is noteworthy that we can establish an obvious parallel development. Thus, the burial custom also changes around the beginning of the birth of Christ from a cremation grave custom to an inhumation grave custom. This coincidence probably indicates that within the two different religious and ritual contexts, the “ritual language” is to some degree identical when it comes to passing on humans and sacrificial animals.Irrespective of the superior sacrificial context – a bog, a lake, a field, a meadow, a structure, or a settlement – both the sacrifice intensity and the sacrificed objects seem to be based on objects from the daily household. As shown in the case of Nr. Tranders, the sacrifices occur in such large numbers on settlements with optimal preservation conditions that it is impossible to maintain the thesis that the Iron Age people had an especially one-sided preference for performing the sacrificial rituals in connection with wetland areas.As a supplement to the archaeological evidence, archaeologists have often sought support in historical accounts written by Romans in the centuries around the birth of Christ. The Roman historian Tacitus’ description of the religious activities of the Teutons is particularly describing and geographically differentiated. He mentions some general features such as the Teutons mainly worshipping Mercury (Mercury is the god of fertility, shepherds, etc.) and that they consider it a sacred duty even to bring him a human sacrifice on fixed days (i.e. a sacrifice cycle). Hercules and Mars (gods of strength and war) can only be reconciled with the allowed animal sacrifices. Besides, the Teutons consider it incompatible with the grandness of the heavenly powers to close them in behind walls and give them human features (cf. the lacking iconography). Tacitus´ overall description of the religion of the Teutons is thus primarily dealing with fertility sacrifices in relation to Mercury and the sacrifice of humans on certain days, i.e. a sacrifice cycle.More specifically, Tacitus describes the religious practice performed by tribes in South Scandinavia and North Germany at the time immediately succeeding the birth of Christ:“Nor in one of these nations does aught remarkable occur, only that they universally join in the worship of Nerthus; that is to say, the Mother Earth [Nerthus is phonetically concordant with the name Njord, a fertility goddess known from Norse mythology]. Her they believe to interpose in the affairs of man, and to visit countries. In an island of the ocean stands the wood Castum: in it is a chariot dedicated to the Goddess, covered over with a curtain, and permitted to be touched by none but the Priest. Whenever the Goddess enters this her holy vehicle, he perceives her; and with profound veneration attends the motion of the chariot, which is always drawn by yoked cows. Then it is that days of rejoicing always ensue, and in all places whatsoever which she descends to honour with a visit and her company, feasts and recreation abound. They go not to war; they touch no arms; fast laid up is every hostile weapon; peace and repose are then only known, then only beloved, till to the temple the same priest reconducts the Goddess when well tired with the conversation of mortal beings. Anon the chariot is washed and purified in a secret lake, as also the curtains; nay, the Deity herself too, if you choose to believe it. In this office it is slaves who minister, and they are forthwith doomed to be swallowed up in the same lake. Hence all men are possessed with mysterious terror; as well as with a holy ignorance what that must be, which none see but such as are immediately to perish.”Traditionally, the text is solely related to the numerous bog finds from the period. The question is, however, whether this is appropriate? Even a very limited analysis of the content of the text clearly reveals that the described religious exertion and the traces it must have left in the archaeological material can only be partly described from the numerous sacrificial bogs. The account of Nerthus may be split into two separate parts. One part that describes the common religious actions and another part comprising rituals carried out by a narrower group of people. The ritual mentioned with a severely limited circle (priest and slaves) comprises the washing of the goddess’ chariot by a lake and the succeeding sacrifice of the slaves chosen for the task. Far larger does the participant group appear throughout the rest of the Nerthus story. At first, there is a short mentioning of Nerthus driving about to the different tribes! This may be interpreted in such a way that the rituals described comprise actions, which take place where people are primarily moving about, i.e. in the villages! Perhaps the larger settlements of the Early Iron Age play a central part in relation to such common society-supporting ritual traditions. Tacitus decribes the physical context to be able to change its rules and norms at this sudden religious activity (cf. “They go not to war; they touch no arms.”) and in this way change sphere from an everyday, secular context to a religious context – a sacrosanct condition arises. The settlement thus enters different spheres at different times! Tacitus´ account of the execution of and the setting for the practiced ritual structure thus closely follows the structure known from archaeological excavations of bogs and settlements.How, then, does the religious practice of the Early Iron Age – and its sacrificial part in particular – appear on the background of the analyses above? (Fig. 22). May the sacrificial activity in actual fact be divided into two overriding groups, as was previously the tradition – individual structure sacrifices on settlements and both common and individual sacrifices in wetland areas – or is it necessary to revise and differentiate this view of Early Iron Age religion and the sacrificial customs in particular?The very unbalanced picture of the ritual displays of the society, involving chosen bogs as an almost “church-like” forum, is neither expressed in the archaeological material nor in the few written sources. On the contrary, the sacrificial activity appears as a very complex area, completely connected to the time and the regional development of the society of which it was part. Sacrificial objects primarily comprising everyday objects in the form of food, earthenware, animals, and humans did not differ from the secular culture until the actual ritual act took place.Considering the fact that the sacrificial objects comprised a wide range of everyday items, it is perhaps not so strange that the context in which the objects were sacrificed also varied considerably. It thus seems as if the conventional sacrificial customs were attached to the complete active resource area of the settlements, both in the form of wetland areas, and to the same degree of settlements. The conditions concerning burial sites, field systems, grazing areas, border markings, etc. still appear unclear, although it can be established that here, too, ritual activities took place according to the same conventions.The exertion of the rituals constituted a just as varied picture during the Early Iron Age as did the choice of sacrificial objects and place of sacrifice. Thus, we see objects deposited intact, as pars pro toto, smashed, burnt, etc. In spite of this very complex picture, patterns do seem to occur. There are thus strong indications that the rituals connected to settlement sacrifices of humans and animals during the Early Iron Age are closely connected with the rituals attached to the burial custom, and as such mirror a conventional communication form between humans and gods. Conversely, it seems as if structure sacrifices through all of the Early Iron Age primarily occur unburnt and that the ritual make-up connected to the finds of structure sacrifices is thus detached from the previously mentioned types of sacrifice, whereas the actual selection of the sacrificial objects seem to follow the same pattern.It is a characteristic of the ritual environments of the Early Iron Age that they appear momentary and as part of the daily life in the peasant community. Much thus indicates that permanent sacred environments and buildings did not exist to any particularly large degree. This does not imply that people would not return to the same sacred sacrificial places but rather that in between the sacrifices, these places formed part of the daily life, just as all the other parts of the cultural landscape.The examination of both published and unpublished material shows that the settlements were parallel contexts to the wetland areas and that these two contexts probably supplemented each other within the religious landscape of the Early Iron Age. In the light of the sacrificial find material there is no need to make a strong distinction between the religious societal roles of the settlements as opposed to the wetlands. The context (wetland and settlement) cannot in itself be understood as a useful parameter for determining whether we are dealing with large collective society-supporting ritual sites or sites connected to a minor village community. The question is whether the variation of sacrificial contexts should be related to different deities and myths, i.e. the mythical and narrative dimension of the religion, rather than to the size of the group of participants. On a few settlements, metal vessels, chariots, and humans were sacrificed – find types that are traditionally associated with the bogs and with groups of participants from a larger area than the individual settlement. This interpretation should also be applied to the settlements.In spite of the fact that from an overall perspective, the practiced religion in South Scandinavia seems homogenous, there is neither archaeological nor historical evidence for the presence of real ritual and religious units comprising large areas, such as complete provinces. However, we must assume that sacrifices of for instance humans, chariots, cauldrons, and the large weapon accumulations were made by groups of people exceeding the number of inhabitants in a single settlement. We thus have no reason for questioning the traditional concept that chosen wetland areas functioned as sacred places from time to time to major sections of the population – whether the sacrifices were brought about by for instance acts of war or as part of a cyclic ritual. The question is whether the large settlements of the Early Iron Age did not play a similar part to a hinterland consisting of a number of minor settlements, as the comprehensive finds from for instance the settlement mounds near Aalborg seem to indicate.During the Late Roman Iron Age and Early Germanic Iron Age, the previously so comprehensive sacrificial activity connected to the wetlands declined considerably. Parallel to this, the frequent settlement-related fertility sacrifices of bones and earthenware vessels in the Early Iron Age recede into the background in favour of knives, lances, craftsmen’s tools, and prestigious items representing the changed society of these centuries. During the Late Iron Age, the iconographic imagery, after having been throttled down for almost a millennia, regains a central role within the religion. This happens by virtue of a varied imagery on prestigious items such as bracteates and “guldgubber,” cf. Fig. 21. Seen as a whole, it seems as if – parallel to the development of the society during the Late Roman Iron Age and the Early Germanic Iron Age – there is a dimension displacement within the ritual and religious world, which manifests itself in an increased focus on the material dimension. The question is whether this very dimension displacement is not reflecting the religious development from the fertility-related Vanir faith to the more elitist Æsir faith.Jesper HansenOdense Bys Museer Translated by Annette Lerche Trolle

Abstract Global increases in temperatures and urbanization are impacting the epidemiology of mosquito-borne diseases. Urbanization processes create suitable habitats for vector mosquitoes in which there are a reduced number of predators, and human hosts are widely available. We hypothesize that mosquito vector species, especially Aedes aegypti, are locally concentrated primarily in those specific habitats at the neighborhood levels that provide suitable conditions and environmental resources needed for mosquito survival. Determining how mosquito vector species composition and abundance depend on environmental resources across habitats addresses where different types of vector control need to be applied. Therefore, our goal was to analyze and identify the most productive aquatic habitats for mosquitoes in Miami-Dade County, Florida. Immature mosquito surveys were conducted throughout Miami-Dade County from April 2018 to June 2019, totaling 2,488 inspections. Mosquitoes were collected in 76 different types of aquatic habitats scattered throughout 141 neighborhoods located in the urbanized areas of Miami-Dade County. A total of 44,599 immature mosquitoes were collected and Ae. aegypti was the most common and abundant species, comprising 43% of all specimens collected. Aedes aegypti was primarily found in buckets, bromeliads, and flower pots, concentrated in specific neighborhoods. Our results showed that aquatic habitats created by anthropogenic land-use modifications (e.g., ornamental bromeliads, buckets, etc.) were positively correlated with the abundance of Ae. aegypti. This study serves to identify how vector mosquitoes utilize the resources available in urban environments and to determine the exact role of these specific urban features in supporting populations of vector mosquito species. Ultimately, the identification of modifiable urban features will allow the development of targeted mosquito control strategies optimized to preventatively control vector mosquitoes in urban areas.

AbstractPlatelet-targeted FVIII gene therapy can efficiently recover bleeding phenotype for hemophilia A (HA), yet characteristics of thrombus formation with this ectopic expression of factor VIII (FVIII) in platelets remain unclear. Here, we generated 2bF8trans mice restrictively expressing human B-domain–deleted FVIII (hBDD FVIII) in platelets on a hemophilic (FVIIInull) mice background. The results showed no statistical difference in clot strength and stability between wild-type (WT) and 2bF8trans mice, but with a prolonged reaction time (R-time), by thromboelastography. Fluid dynamics analysis showed that at the shear rates of 500 to 1,500 s−1, where physiological hemostasis often develops, the thrombi formed in 2bF8trans mice were more stable than those in FVIIInull mice, while at high pathological shear rates (2,500 s−1), mimicking atherosclerosis, thrombus size and fibrin deposition in 2bF8trans mice were less than those in WT mice. Thrombus morphology analysis showed that there was a locally concentrated deposition of fibrin in thrombus at the injured site and fibrin co-localized with activated platelets in 2bF8trans mice. Moreover, a higher ratio of fibrin to platelets was found in thrombus from 2bF8trans mice following laser-induced injury in cremaster arterioles, which might be the underlying mechanism of thrombus stability in 2bF8trans mice at physiological arterial circumstance. These observations suggest that specific morphological features of the thrombi might contribute to the efficacy and safety of platelet-targeted FVIII gene therapy for HA.

Abstract Background The global burden of sepsis is concentrated in sub-Saharan Africa, where severe infections disproportionately affect young, HIV-infected adults and high-burden pathogens are unique. In this context, poor understanding of sepsis immunopathology represents a crucial barrier to development of locally-effective treatment strategies. We sought to determine inter-individual immunologic heterogeneity among adults hospitalized with sepsis in a sub-Saharan African setting, and characterize associations between immune subtypes, infecting pathogens, and clinical outcomes. Methods Among a prospective observational cohort of 288 adults hospitalized with suspected sepsis in Uganda, we applied machine learning methods to 14 soluble host immune mediators, reflective of key domains of sepsis immunopathology (innate and adaptive immune activation, endothelial dysfunction, fibrinolysis), to identify immune subtypes in randomly-split discovery (N = 201) and internal validation (N = 87) sub-cohorts. In parallel, we applied similar methods to whole-blood RNA-sequencing data from a consecutive subset of patients (N = 128) to identify transcriptional subtypes, which we characterized using biological pathway and immune cell-type deconvolution analyses. Results Unsupervised clustering consistently identified two immune subtypes defined by differential activation of pro-inflammatory innate and adaptive immune pathways, with transcriptional evidence of concomitant CD56(-)/CD16( +) NK-cell expansion, T-cell exhaustion, and oxidative-stress and hypoxia-induced metabolic and cell-cycle reprogramming in the hyperinflammatory subtype. Immune subtypes defined by greater pro-inflammatory immune activation, T-cell exhaustion, and metabolic reprogramming were consistently associated with a high-prevalence of severe and often disseminated HIV-associated tuberculosis, as well as more extensive organ dysfunction, worse functional outcomes, and higher 30-day mortality. Conclusions Our results highlight unique host- and pathogen-driven features of sepsis immunopathology in sub-Saharan Africa, including the importance of severe HIV-associated tuberculosis, and reinforce the need to develop more biologically-informed treatment strategies in the region, particularly those incorporating immunomodulation.

The ca. 30 km 3 Taupo ignimbrite was erupted as a climax to the ca. AD 186 Taupo eruption in the central North Island of New Zealand. It was erupted as a single vent-generated flow unit over a time period of ca. 400 s and was emplaced very rapidly (locally at more than 250-300 m s -1 ) and violently. The parent flow reached 8 0 + 10 km from source in all directions, crossed all but one of the mountains within its range and only stopped when it ran out of material. The ignimbrite is divisible into layers 1 and 2, and a distant facies which combines features of both layers. Layer 1 was generated as a result of strong fluidization in the flow head, caused by air ingestion, and consists of two main facies. Layer 1(P) is a pumiceous, mildly to strongly fines-depleted unit, generated by the expulsion of material from the flow front, and termed the jetted deposits. The overlying layer 1 (H) is a thinner, crystal- and lithic-rich, fines-depleted unit, generated by the sedimentation of coarse/dense constituents segregated out by strong fluidization within the flow head and termed the ground layer. Layer 2 consists of two facies with similar compositions but contrasting morphologies; during emplacement, material left behind by the flow body partially drained into depressions to form the valley-ponded ignimbrite, leaving the veneer deposit as a thin, landscape mantling layer on interfluves. The distant facies occurs in some outermost hilly areas of the ignimbrite where the flow velocity remained high but its volume had shrunk through deposition so that air ingestion fluidization affected the whole flow. The ignimbrite shows great lateral variations. Each facies, or variants therein, exhibits systematic degrees of development with varying distances from vent. Near vent, the flow consisted of a series of batches of material which by ca. 25 km had coalesced into a single wavy flow and by ca. 40 km into a single wave. Out to ca. 13 km, the flow was rather dilute and highly turbulent as it deflated from the collapsing eruption column. Beyond this distance it was fairly concentrated, being less than 100% expanded over its non-fluidized compacted state, and had acquired a fluidization-induced stable density stratification, which strongly suppressed turbulence in the flow body. Deflation from the eruption column was largely complete by ca. 13 km but influenced the flow as far as 20-25 km from vent. Grainsize and compositional parameters measured in the ignimbrite show lateral variations which equal or exceed the entire spectrum of published ignimbrite data. The flow had deflated and coalesced from the eruption column by ca. 20 km from vent. Beyond this distance most lateral variations are modelled by considering the flow to be a giant fluidized bed. As the flow moved, material was deposited from its base, and hence predictable vertical variations in the model fluidized bed are comparable with lateral variations in the ignimbrite. The agreement is excellent, and, in particular, discontinuities in the nature of the ignimbrite at 55-60 km from vent suggest that the more distal ignimbrite represents a vast segregation layer generated above the moving flow. Differences between the model and variations of some parameters reflect the influence of kinetic processes, such as shearing and local fluidization, that operated regardless of the bulk flow composition. The strong fluidization in the flow is a result of the high flow velocities (promoting air ingestion), not vice versa as is often accepted. Contrasts in the natures of layers 1 and 2 imply that the first material erupted contained significantly coarser, and a higher content of, lithics than the bulk of the flow. During emplacement, this earlier material was depleted by deposition and diluted by material introduced from the flow body. Systematic regional variations also occur in the ignimbrite: for example, it contains lower crystal: lithic ratios and higher density pumice in a northeasterly sector, and vice versa to the southwest. Ignimbrite found in mountainous areas shows changes consistent with its derivation from the upper, more mobile and pumiceous top of the flow. Fluidization processes generated structures and facies in the ignimbrite on various scales. Individual segregation bodies found at any exposure show features mimicking those of the ground layer, i.e. fines depletion and crystal- and lithic-enrichment. Fluidization-induced grading visible at individual exposures accounts for the great range of grading styles seen in the valley-ponded ignimbrite, and strong fluidization has locally generated an upper fines- and pumice- rich segregation layer (here termed layer 2c). On the largest scale, fluidization was primarily responsible for the generation of the layer 1 deposits, and for the grainsize and compositional zonation within the flow that produced the lateral variations in the ignimbrite. Ingested and heated air is inferred to have been the most important gas source for fluidization within the flow, although several other gas sources were locally dominant. It is clear that the thickness, grainsize and composition of the ignimbrite at any point are not simply related to values of these parameters in either the originally erupted material or the parent flow, and that, except for its density, the dimensions and composition of the parent flow cannot be directly inferred from the ignimbrite.

This article examines the role played by commercial advertising in promoting images of city reconstruction and architectural modernity within Manila in the years immediately following the end of the Second World War. It concentrates on the leading English-language daily, the Manila Times, which, from early 1946, began publishing advertisements that featured dramatic images of a future city of skyscrapers and other buildings rising out of the ruins of war. Advertisers called out to readers to contribute to the process of economic recovery by purchasing newly arrived shipments of goods and equipment and to support their efforts to drive property investment and the reconstruction of the city. By 1947 publicity was extending into home construction and advertisements incorporated illustrations of modernist houses as a means of promoting imported building products from the United States as well as locally manufactured materials. The article examines these advertisements for what they reveal about the stimulation of public interest in urban and architectural modernity within the Philippines in the early postwar years.

AbstractThe uneven spatial distribution of biodiversity is a defining feature of nature. In fact, the implementation of conservation actions both locally and globally has progressively been guided by the identification of biodiversity ‘hotspots’ (areas with exceptional biodiversity). However, different regions of the world differ drastically in the availability of fine-scale data on the diversity and distribution of species, thus limiting the potential to assess their local environmental priorities. Within South America—a megadiverse continent—Uruguay represents a peculiar area where multiple tropical and non-tropical eco-regions converge, creating highly heterogeneous ecosystems, but where the systematic quantification of biodiversity remains largely anecdotal. To investigate the constraints posed by the limited access to biodiversity data, we employ the most comprehensive database for tetrapod vertebrates in Uruguay (spanning 664 species) assembled to date, to identify hotspots of species-richness, endemism and threatened species for the first time. Our results reveal negligible spatial congruence among biodiversity hotspots, and that tetrapod sampling has historically concentrated in only a few areas. Collectively, our study provides a detailed account of the areas where urgent biodiversity monitoring efforts are needed to develop more accurate knowledge on biodiversity patterns, offering government and environmental bodies a critical scientific resource for future planning.

Abstract Background Current intra-tumoral heterogeneous feature extraction in radiology is limited to the use of a single slice or the region of interest within a few context-associated slices, and the decoding of intra-tumoral spatial heterogeneity using whole tumor samples is rare. We aim to propose a mathematical model of space-filling curve-based spatial correspondence mapping to interpret intra-tumoral spatial locality and heterogeneity. Methods A Hilbert curve-based approach was employed to decode and visualize intra-tumoral spatial heterogeneity by expanding the tumor volume to a two-dimensional (2D) matrix in voxels while preserving the spatial locality of the neighboring voxels. The proposed method was validated using three-dimensional (3D) volumes constructed from lung nodules from the LIDC-IDRI dataset, regular axial plane images, and 3D blocks. Results Dimensionality reduction of the Hilbert volume with a single regular axial plane image showed a sparse and scattered pixel distribution on the corresponding 2D matrix. However, for 3D blocks and lung tumor inside the volume, the dimensionality reduction to the 2D matrix indicated regular and concentrated squares and rectangles. For classification into benign and malignant masses using lung nodules from the LIDC-IDRI dataset, the Inception-V4 indicated that the Hilbert matrix images improved accuracy (85.54% vs. 73.22%, p < 0.001) compared to the original CT images of the test dataset. Conclusions Our study indicates that Hilbert curve-based spatial correspondence mapping is promising for decoding intra-tumoral spatial heterogeneity of partial or whole tumor samples on radiological images. This spatial-locality-preserving approach for voxel expansion enables existing radiomics and convolution neural networks to filter structured and spatially correlated high-dimensional intra-tumoral heterogeneity.
