Abstract:
In the Moscow region, Eopleistocene deformations (1,8 million years) were studied for the first time. The activity of modern geological processes is associated with them. The qualitative and quantitative characteristics of deformations were carried out on the basis of the structural-geodynamic method and morphometric analysis of a large array of GIS data. The stage-by-stage amplitudes and velocities of neotectonic uplifts have been estimated. And the gradient of the strain rate of the Moskvoretskaya zone was calculated.

Abstract:
Quaternary formations (detrital and weathered materials) are an important natural resource for different areas of scientific investigation, from understanding their relation to erosive processes and morphodynamic processes that create landforms or to understanding the history of the first human settlements (geoarcheology). Quaternary coverings can be formed in situ or be transported by external geologic agents. Regarding soils, Quaternary formations are related to landscape topography and are transformed according to the characteristics of this topography. Hence, classifying and mapping these soils is not always easy. The present article aims to map the Quaternary formations along a stretch of the Uruguay River basin known as Volta Grande (SC/RS-Brazil), by using topographic attributes derived from the SRTM GL1-Up Sampled digital elevation model, soil particle-size analysis, and a generated Multiresolution Index of Valley Bottom Flatness (MRVBF) index . The results of the analysis show that: (i) colluvium is the predominant Quaternary formation in the study area; (ii) there is a predominance of clay, corroborating previous studies of the region; (iii) the spatial distribution of the study area’s Quaternary formations reflect local slope dynamics based on morphology and topographic position; and, (iv) the existence of colluvium-alluvium on the Uruguay River’s banks indicates that slope attributes contributed to the pedogeomorphological dynamics of the study area and not only fluvial dynamics. Based on the results, the methodology applied in this study might be useful for pedogeomorphological studies, notably in the analysis and mapping of Quaternary formations, despite some of its limitations.

Abstract:
As a result of the convergence between the Arabian plate and the Anatolian block, a continentcontinent collision occurred in the region along the Bitlis Zargos sutur zone. Following the collision, volcanic activity began in the Late Miocene and produced volcanic material throughout the region and reach to the Caucasus. Collision-related volcanism in eastern Anatolia covered almost two-thirds of the area and formed volcanic products up to 1 km thick. In order to determine the tectonic evolution of Mount Nemrut and its around, paleomagnetic core samples were collected from a total of 11 sites from Pleistocene - Holocene time interval aged volcanic rocks. Paleomagnetic laboratory studies were carried out in KANTEK Paleomagnetism Laboratory, and also rock magnetism studies were carried out in Istanbul University-Cerrahpaşa, Yılmaz İspir Paleomagnetism Laboratory. When the mean magnetization directions obtained from Mount Nemrut and its surrounding Holocene and Upper Pleistocene aged locations are examined, it is seen that there is an average of 7.3° clockwise rotation. It is also observed that the angle of inclination is 60°. These results obtained, considering the α95 circle (7.7°), it is observed that there is no tectonic rotation within the sensitivity limits of paleomagnetism in the region. At the same time, it can be interpreted that Mount Nemrut has not been exposed to a latitudinal movement since the Quaternary, but volcanics is still at the latitude where it was formed.

Abstract:
In recent years basic regional geological mapping of northern Libya by the Industrial Research Centre, Tripoli, together with the UNESCO Libyan Valleys Survey of eastern Tripolitania and the work of the author and Dr S. M. Ghellali in the Jifarah Plain and Jabal Nafusah, have greatly added to our knowledge of Quaternary deposits in the region. This work is described and evaluated against the background of earlier studies. The succession of major depositional, soil forming and erosional events which characterise the fluvio-aeolian deposits of the Jifarah Formation can be recognised in, and thus used to subdivide, laterally equivalent aeolianite, fangravel and wadi gravel deposits in the Jifarah Plain. Comparisons of this succession with others from throughout the region indicate that the events are of regional significance and that the Jifarah sequence provides a sound framework for lithostratigraphic correlation and a basis for facies analysis and chronostratigraphic studies.This review is largely limited to the northern margins of Libya north of the 30th parallel (Fig. 1). It is convenient to subdivide the zone into several regions. These are:(a) The Jifarah Plain and foothills of the Jabal Nafusah.(b) The Hammada Al Hamra Plateau and major valleys of eastern Tripolitania.(c) The coastal region from Misratah to Ajdabiyah.(d) Cyrenaica from Soluq to Al Bardia.

Abstract:
This study reports on the geometric and structural characteristics of the North Anatolian Fault Zone in the southwest Marmara region. The geometric and kinematic features of the faults in the region are described, based on field observations. In addition, the Neogene and Quaternary basin fill which occupies large areas in the region has been determined, and the tectonic regimes controlling these basins are explained. The neotectonic regime is also explained considering different deformation phases affecting the region. The N–S extension and E–W strike-slip have affected the region possibly since the latest Pliocene–Quaternary. Field observations show that these extensional tectonics around the south Marmara region are related to right strike-slip on the E–W North Anatolian fault zone and the N–S Aegean extensional system. The faults in this zone trend approximately E–W in the eastern part of the region and NE–SW towards the west of the region, indicating that they accommodate rotation in addition to differential movement between adjacent blocks.

Abstract:
ABSTRACT The Canadian Rocky Mountains figured prominently during the glacial history of western Canada. First as a western limit or boundary to the Laurentide Ice Sheet, second as an eastern margin of the Cordilleran Ice Sheet, and finally as a centre of local Montane ice. Throughout the Quaternary, complex interactions of glacier ice from these three ice sources markedly changed the physical form of the Rocky Mountains, Trench and Foothills areas. Investigations into the Quaternary history of this region have been ongoing since the beginning of the last century. Since about 1950, the number of studies performed in this area have increased significantly. This paper briefly reviews the historical accomplishments of Quaternary work in the region up to the period of about 1950. From this time to the present, individual study efforts are examined in detail according to the three geographic regions: 1) the northern Rocky Mountains (from the Liard Plateau south to the McGregor Plateau), 2) the central Rocky Mountains (from the McGregor Plateau south to the Porcupine Hills) and 3) the southern Rocky Mountains (from the Porcupine Hills south to the international border). In the northern region, geologic data suggest a maximum of two Rocky Mountain glaciations and only one Laurentide glaciation and no ice coalescence. In the central region, three of four Rocky Mountain events, and at least two Laurentide events are known. Only in the central region is there good evidence for ice coalescence, but the timing of this event is not clearly established. In the south, at least three Rocky Mountain episodes and a variable number of Laurentide episodes are recognized. There is no evidence for ice coalescence. A number of facts support the proposal that Cordilleran ice crossed the Continental Divide and joined with local Montane ice at several locations. However, this expansion of western ice occurred before the Late Wisconsinan in all areas but Jasper. In general, the chronological data presented suggest that the Late Wisconsinan glaciation in the Rocky Mountains was a short-lived event which started around or after 20 ka years ago and ended before 12 ka ago.

Full text
Abstract:
The Fc portion of immunoglobulin G (IgG) is a horseshoe-shaped homodimer, which interacts with various effector proteins, including Fcγ receptors (FcγRs). These interactions are critically dependent on the pair of N-glycans packed between the two CH2 domains. Fucosylation of these N-glycans negatively affects human IgG1-FcγRIIIa interaction. The IgG1-Fc crystal structures mostly exhibit asymmetric quaternary conformations with divergent orientations of CH2 with respect to CH3. We aimed to provide dynamic views of IgG1-Fc by performing long-timescale molecular dynamics (MD) simulations, which were experimentally validated by small-angle X-ray scattering and nuclear magnetic resonance spectroscopy. Our simulation results indicated that the dynamic conformational ensembles of Fc encompass most of the previously reported crystal structures determined in both free and complex forms, although the major Fc conformers in solution exhibited almost symmetric, stouter quaternary structures, unlike the crystal structures. Furthermore, the MD simulations suggested that the N-glycans restrict the motional freedom of CH2 and endow quaternary-structure plasticity through multiple intramolecular interaction networks. Moreover, the fucosylation of these N-glycans restricts the conformational freedom of the proximal tyrosine residue of functional importance, thereby precluding its interaction with FcγRIIIa. The dynamic views of Fc will provide opportunities to control the IgG interactions for developing therapeutic antibodies.

Abstract:
Late Quaternary (Eemian) deposits of the Netherlands contain shells that resemble those of living Mytilus galloprovincialis. Similar broad-shelled mytilids also occur in estuaries of the southwestern Netherlands together with slender individuals typical of M. edulis. We sampled living mussels along a depth gradient in the Oosterschelde to a) investigate whether a relation exists between shell shape and depth, b) test if the broadshelled specimens might represent M. galloprovincialis (or a hybrid with M. edulis) and c) assess by inference if the Quaternary specimens might be attributed to M. galloprovincialis as well. In order to do so, we compared genetic (length polymorphism of Me 15/16, COIII sequences and AFLPs) and shellmorphological characteristics (juvenile L/W ratios and socalled Verduin parameters) of the same specimens. The obtained dataset indicates that all studied mussels from the Oosterschelde should be attributed to M. edulis, including those with broad shell outlines. No correlation of shell-morphology and depth-distribution was found. The worn and generally damaged state of the Eemian specimens precluded measurement of the Verduin parameters, while juvenile L/W ratios turned out not to be diagnostic. Therefore the shell characters examined in this study are insufficient to demonstrate the possible presence of M. galloprovincialis shells in Quaternary deposits of the Netherlands.

Abstract:
The late Quaternary sequences of north-eastern Algeria composed of alternating dark and light layers, which are rich in molluscan fauna, could correspond to synchronous environmental phases. The facies variations of the Morsott Region deposits were systematically sampled as part of a sedimentological and malacological study in order to establish a palaeoenvironmental and climatic reconstruction of the late Quaternary. The alternation of sandy clayey silts levels, which contain abundant molluscan hygrophilous organisms, indicates an isostasis cycle followed, at the top, by a succession of rhexistasis and biostasis cycles. The molluscan record shows a dominant succession of xerophilous organisms in relation to the hygrophilous organisms. The faunistic richness in the fine levels is linked to sub-humid periods where the region has suffered numerous floods. The reduction in the number of species in the coarse levels comes is likely due to desiccation when the climate was semi-arid. This study is new in Algeria and will provide an insight into climatic changes. Further research will be required in order to understand the fluvial dynamics during the Quaternary.

Microstructural investigations confirmed the existence of a continuous A1-L12 two-phase region in the Ni-Co-Al-Ti quaternary system between Ni-Ni3Al and Co-Co3Ti. The lattice misfits of alloys from this quaternary system were determined using neutron diffraction. With increasing contents of Ti the positive lattice misfit increases up to +0.79% in the Ti-containing alloys, which leads to an increasing tetragonal distortion of the  matrix phase due to the increasing coherency stresses.

Abstract:
Given the scarcity, or even absence, of surface water and the domination of the semi-arid climate in the coastal zone of the Essaouira basin (Morocco), the Plio-Quaternary, Turonian, Barremian–Aptian and Hauterivian aquifers represent the main source of water for fine consumption and agriculture. However, the study of their quality is a priority. So as to reach the objective of this study, the combination of the two hydrogeochemical and geographical information system tools was used. The results obtained showed that the facies characterising the Plio-Quaternary aquifer was a combination of Ca–Mg–Cl and Na–Cl, and that characterising the Turonian, Barremian–Aptian and the Hauterivian aquifer was a combination of Ca–Mg–Cl. However, flagship ions in the study area are Cl, Na, Ca and Mg. For consumptions purpose, the comparison of the concentrations of major elements with the standards of the World Health Organization showed that all the elements presented concentrations below the threshold, except for chlorides, the concentrations of which exceeded the threshold. For the agricultural purposes, the two Wilcox and United States Salinity Laboratory (USSL) diagrams, and the spatial distribution of parameters total dissolved solids, total hardness, permeability Kelly’s ratio, sodium hazard, sodium percentage and nitrates showed that the groundwater in the study area is adequate for persistent plants with a high to very high salinity tolerance.

Abstract:
Based on a comprehensive structural-morphometric analysis, Earth remote sensing data and GIS analysis, the evolution of the paleorelief of the right bank of the Middle Dnieper in the recent period is reconstructed. Based on the stepwise morphostructural-neotectonic analysis, morphodynamic and evolutionary trends in the landscape relief of this region are traced. Three morphostructures (Kyiv, Obukhiv, Kanevskaya-Trakhtemirovsky blocks) were identified and characterized. Quantitative indicators of the relief were determined during each stage, and the total oscillation amplitudes were analyzed both over short time intervals and for the entire Neogene-Quaternary period. On the whole, the amplitude of fluctuations in the elevations of the relief of the Middle Dnieper in the Neogene-Quaternary period in the northern part was 100 m, in the southern – 135 m. The differentiated nature of neotectonic movements and the change in their activity over time were reconstructed. It was confirmed that the northern regions of the region had an active upward dynamics of movements in the Neogene era, and the southern ones in the Quaternary.The modern stage marks the opposite phenomenon – the north-eastern regions rise again and the south-western ones fall.The obtained data can serve as a basis for analyzing the influence of tectonic movements on the activation of dangerous geological processes within the Middle Dnieper and forecasting their development in the future.

Abstract:
The article evaluates the morphostructural construction of the Czech part of the Čantoryjská hornatina Hilly Region with taking full advantage of a detailed geomorphologic mapping and multicriterial morphostructural analysis. As a result of the upper Tertiary and Quaternary neotectonics, there arose a graded internally ranged morphostructure with features of vaulted deformations and faults.

Abstract. The strength of Southern Hemisphere westerlies, as well as the positions of the subtropical front (STF), Agulhas Current (AC) and Agulhas Return Current (ARC) control the hydrography of the southwestern Indian Ocean. Although equatorward migration of the STF and reduction in Agulhas leakage were reported during the last glacial period, the fate of ARC during the last glacial–interglacial cycle is not clear. Therefore, in order to understand changes in the position and strength of ARC during the last glacial–interglacial cycle, here we reconstruct hydrographic changes in the southwestern Indian Ocean from temporal variation in planktic foraminiferal abundance, stable isotopic ratio (δ18O) and trace elemental ratio (Mg/Ca) of planktic foraminifera Globigerina bulloides in a core collected from the Agulhas Recirculation Region (ARR) in the southwestern Indian Ocean. Increased abundance of G. bulloides suggests that the productivity in the southwestern Indian Ocean increased during the last glacial period which confirms previous reports of high glacial productivity in the Southern Ocean. The increased productivity was likely driven by the intensified Southern Hemisphere westerlies supported by an equatorward migration of the subtropical front. Increase in relative abundance of Neogloboquadrina incompta suggests seasonally strong thermocline and enhanced advection of southern source water in the southwestern Indian Ocean as a result of strengthened ARC, right through MIS 4 to MIS 2, during the last glacial period. Therefore, it is inferred that over the last glacial–interglacial cycle, the hydrography of the southwestern Indian Ocean was driven by strengthened westerlies, ARC as well as a migrating subtropical front.
