Abstract:

SUMMARY In addition to enabling the physical processes of volcanic systems to be better understood, seismology has been also used to infer the complexity of magma pathways and plumbing systems in steep-sided andesitic and stratovolcanoes. However, in these volcanic environments, the application of seismic location methods is particularly challenging and systematic comparisons of common methods are lacking. Furthermore, little is known about the characteristic seismicity and deep structure of Lascar volcano, one of the most historically active volcanoes in northern Chile known to produce VEI-4 eruptions. To better understand the inner processes and deep structure of Lascar, the local broad-band seismic monitoring network was densified during a temporal installation in 2014–2015. Herein, we focus on the local seismicity during the 2014–2015 unrest episode, during which we recorded numerous seismic events mainly classified as long-period (LP) type, but also denote volcano-tectonic (VT) activity. Specifically, a long-lasting phase of LP activity is observed over a period of ∼14 months that starts in tandem with a pulse of VT activity. The LP rate and amplitude are modulated over time; they are lower in the initial phase, rise during the intermediate period from October 2014 to July 2015, and finally slowly decay while approaching the eruption time. The location of LPs is challenging due to the typical lack of clear seismic onsets. We thus encompass this problem by comparing a broad range of different standard and novel location techniques to map the source region of LPs by fitting the amplitude decay, polarization patterns, coherence of characteristic functions and cross-correlation differential times. As a result, we principally constrain LP locations within the first 5 km depth below the summit extending downward along a narrow, conduit-like path. We identify different regions of complexity: VTs dominate at depth, both VTs and LPs cluster in an intermediate depth region (down to 1.5 km), suggesting a change in the plumbing system geometry, and LPs dominate the shallowest region. Based on these results, we infer the presence of a subvertical conduit extending down to a depth of ∼5 km, and a region of path divergence, possibly accommodating a magma plumbing system, at a depth of ∼3 km beneath the volcano summit. Identifying the locations of complexities in the magma pathways at Lascar may help identify future unrest. The results are compared with independent observations, demonstrating the strength of the location method used herein that will be tested at volcanoes elsewhere.

Abstract:

AbstractThe Subcommittee for Unnamed Minerals of the IMA Commission on New Minerals, Nomenclature and Classification (CNMNC, formerly CNMMN) has developed a codification system that includes the year of publication and qualitative chemical composition for unnamed minerals reported in the literature. Such minerals are divided into two categories: (1) those regarded as being ‘valid as unnamed minerals’ are those that do not correspond to existing species, have not been reported previously and whose published descriptions enable them to be recognized if found elsewhere. (2) Unnamed minerals regarded as being ‘invalid as unnamed minerals’ are those whose published descriptions are inadequate for their confident recognition if found elsewhere, or which correspond to existing mineral species or unnamed minerals published previously.

Abstract:

Abstract We conducted a phytosociological study of the communities hosting the rare and endangered fern Adiantum capillus-veneris in the foothills of the Julian Alps, in Karst and in Istria. Based on a comparison with similar communities elsewhere in the southern Alps (northern Italy) we classified most of the recorded stands into the syntaxa Eucladio-Adiantetum eucladietosum and -cratoneuretosum commutati. Releves from the southern Julian Alps, located in comparatively slightly colder and moister local climate and the dolomite bedrock are classified into the new subassociation -hymenostylietosum recurvirostri subass. nova. Stands with the abundant occurrence of the liverwort Conocephalum conicum, are classified in to the new subassociation -conocephaletosum conici subass. nova. Stands in conglomerate rock shelters along the Soča at Solkan are classified into the new association Phyteumato columnae-Adiantetum ass. nova, a community of transitional character between the classes Adiantetea capilli-veneris and Asplenietea trichomanis.

Abstract:

AbstractTwo metamorphic alteration styles have been observed in basic lavas and volcaniclastic rocks of the Builth Volcanic Series of Ordovician age exposed at Llanelwedd Quarry, in the Builth lnlier, Wales. The first alteration style is characterized by the development of a mineral assemblage comprising albite+chlorite+ sphene+ pumpellyite ± prehnite ± calcite ± white mica, although original textures are largely preserved. This alteration pattern corresponds with that developed in volcanic and volcaniclastic rocks elsewhere in Wales, and which is attributed to the effects of burial. The second alteration style is characterized by the development of metadomains dominated by pumpellyite or, more rarely, prehnite. In the metadomains no original textures are seen in hand specimen. This alteration pattern has, so far, not been observed elsewhere in Wales, and it is here suggested that it might result from a submarine hydrothermal circulation system.

Abstract:

SummaryOur major classification systems (DSM and ICD) face three main problems: the high rates of ‘comorbidity’ that are produced by our present diagnostic rules, the increasing use of ‘not elsewhere classified’ (NEC) by practising clinicians, and the fact that each new edition is longer and more complex than the one preceding it. A major simplification of the chapter structure used by each classification might pave the way to address these problems.

AbstractIn the Ordovician Snowdon Volcanic Group caldera quartz-magnetite-hematite-pyrite assemblages occur in a breccia vein in rhyolitic tuff and vein swarms in basalt. The veins developed pre-cleavage. Elevated levels of tin and tungsten in the veins, and of fluorine in the wall rocks, suggest a magmatic contribution to the mineralising fluids. The chemistry of the veins differs from that of the base-metal sulphide veins found elsewhere in the caldera.

Abstract:

AbstractThe author examines Williams’ appraisal of Collingwood both in his eponymous essay on Collingwood, in the posthumously published Sense of the Past (2006), and elsewhere in his work. The similarities and differences between their philosophies are explored: in particular, with regard to the relationship between philosophy and history and the relationship between the study of history and our present-day moral attitudes. It is argued that, despite Williams usually being classified as an analytic philosopher and Collingwood being classified as an idealist, there is substantial common ground between them. Williams was aware of this and made clear his sympathy for Collingwood; but, nonetheless, the relationship between Williams and Collingwood has not previously been explored in any detail. After establishing the common ground between these philosophers, and the areas of disagreement, the author suggests that both may have something to gain from the other.

Abstract:

AbstractA cementitious backfill has been proposed in many geological disposal concepts for intermediate-level waste and low-level waste in the UK and elsewhere. In this paper, the main features of the chemical evolution of backfill and the associated changes in the near-field pH are illustrated with results from recent work. For example, interaction of the groundwater with calcium silicate hydrate (C-S-H) phases in a backfill is expected to play an important role in the long-term pH-buffering behaviour. Existing experimental data for the dissolution of C-S-H gels are compared with recent experimental results from leach tests on gels of a lower calcium to silicon ratio (C/S) to provide a consistent set of data across the full C/S range. The results confirm that a congruent dissolution point around C/S = 0.8 is approached by leaching from below (i.e. for gels with 0.29 < C/S < 0.8), as well as from above, as reported elsewhere. In addition, a spreadsheet model has been developed to calculate the volume of backfill required at the vault scale to meet specified pH performance criteria. This model includes the major reactions of the backfill with the groundwater, waste encapsulants and waste components. It can also consider the effects of specific waste packages on local pH performance to allow comparison with the vault-scale calculations.

This article offers an approach through administrative and cultural history to the problems associated with gathering and processing data for the Spanish national census of 1920, and by implication for earlier Spanish censuses. It focuses on the Basque province of Guipúzcoa, making use of correspondence between the central statistical office in Madrid, the provincial jefe de estadística and the localities, and of reports on three problematic towns within the province. The issues that emerge regarding ‘undercounting’, the definition of administrative boundaries and the classification of demographic characteristics are set in the wider context of census-taking practices and problems elsewhere in Spain and in other cultures.

Abstract:

The Lower Silurian Osmundsberg K-bentonite is a widespread ash bed that occurs throughout Baltoscandia and parts of northern Europe. This paper describes its characteristics at its type locality in the Province of Dalarna, Sweden. It contains mineralogical and chemical characteristics that permit its regional correlation in sections elsewhere in Sweden as well as Norway, Estonia, Denmark and Great Britain. The <2 μm clay fraction of the Osmundsberg bed contains abundant kaolinite in addition to randomly ordered (RO) illite/smectite (I/S). Modelling of the X-ray diffraction tracings showed the I/S consists of 18% illite and 82% smectite. The high smectite and kaolinite content is indicative of a history with minimal burial temperatures. Analytical data from both pristine melt inclusions in primary quartz grains as well as whole rock samples can be used to constrain both the parental magma composition and the probable tectonic setting of the source volcanoes. The parental ash was dacitic to rhyolitic in composition and originated in a tectonically active collision margin setting.Whole rock chemical fingerprinting of coeval beds elsewhere in Baltoscandia produced a pronounced clustering of these samples in the Osmundsberg field of the discriminant analysis diagram. This, together with well-constrained biostratigraphic and lithostratigraphic data, provides the basis for regional correlation and supports the conclusion that the Osmundsberg K-bentonite is one of the most extensive fallout ash beds in the early Phanerozoic. The source volcano probably lay to the west of Baltica as part of the subduction complex associated with the closure of Iapetus.

We identified 821 individuals with ICD–9 diagnoses, drawn from the Tasmanian Mental Health Register.ResultsNo demographic variables influence the time to readmission. Two groups emerge: those with affective psychoses, and those with neurotic depression, brief depressive reaction and depressive disorders not elsewhere classified. The former group demonstrated shorter times to readmission than the latter. There was no support for a unipolar–bipolar distinction.ConclusionsAffective psychoses have a less favourable outcome than expected. There was support for an endogenous-neurotic distinction.

Abstract:

AbstractWarwickite constitutes about 5% of an outcrop of metamorphosed ultramafic rocks of Precambrian age in North-West Greenland. It occurs as slender grains, several millimetres long, and in anhedral grains up to 5 mm in size, together with forsterite, pleonaste, phlogopite, magnetite ± tourmaline. Post-metamorphic alteration of warwickite produced a network of boron-rich minerals and magnetite. The warwickite, containing up to 9.72% Al2O3, displays a significantly different chemical composition from warwickite elsewhere, such as that in recrystallized limestones from the type locality Warwick, New York, and in lamproitic and carbonatite-like rocks at Jumilla, Spain.

Abstract:

AbstractManic depression, or bipolar disorder, is a multifaceted illness with an inevitably complex treatment. The current article summarizes the current status of our knowledge and practice concerning its diagnosis and treatment. While the prototypic clinical picture concerns the “classic” bipolar disorder, today mixed episodes with incomplete recovery and significant psychosocial impairment are more frequent. The clinical picture of these mixed episodes is variable, eludes contemporary classification systems, and possibly includes a constellation of mental syndromes currently classified elsewhere. Treatment includes the careful combination of lithium, antiepileptics, atypical antipsychotics, and antidepressants, but not all of the agents in these broad categories are effective for the treatment of bipolar disorder.

Abstract:

Abstract Molecular diagnosis in brain tumors has been widely spread after the publication of WHO 2016 classification. But it become a major problem that there are some tumors not to be classified on its criteria, especially in pediatric neuroepithelial tumors. To clarify the characteristics of gliomas in pediatric and adolescent and young adult age (AYA), we picked up 131 neuroepithelial tumors under 30-year-old at Kyoto University and analyze their molecular profiles. Hot spot mutations in IDH1/2, H3F3A, HIST1H3B, TERT promoter, and BRAF were analyzed by Sanger sequencing, and 1p/19q codeletion was examined by FISH or MLPA. With the pathohistological diagnosis and genetic information, all tumors were classified based on WHO 2016 classification. The terms “not otherwise specified” (NOS) and “not elsewhere classified” (NEC) were used based on cIMPACT-NOW. There were 25 glioblastomas and 34 pilocytic astrocytomas, which accounted for a larger percentage than in adult tumors. IDH-wild type gliomas accounted for 55% in diffuse astrocytomas and 69% in anaplastic astrocytomas. The percentages of gliomas with NEC were 50% of oligodendrogliomas and 20% in anaplastic oligodendrogliomas, respectively. Most pilocytic astrocytomas were under 20-year-old (27 patients) and located in infratentorial area (21 patients). Based on WHO 2016 classification, not a few neuroepithelial tumors in pediatric and AYA ages could be classified clearly. These tumors had more different genetic abnormalities than those in adult. Therefore, it may be important to evaluate these tumors with comprehensive genetic analysis.

Abstract:

Based on the 2010-2019 United Nations commodity trade data, this paper has calculated the regional revealed comparative advantage index, export similarity index, trade complementarity index and intra-industry trade index of trade between Uzbekistan and the member states of the Eurasian Economic Union. This paper analyses the competitiveness and complementarity of trade between Uzbekistan and the member states of the Eurasian Economic Union. Uzbekistan and the Eurasian Economic Union member countries have a high degree of similarity in the export of commodities. There is a certain degree of competitiveness in commodities exported to the same market. However, there are differences in the structure of commodity trade among member states. Uzbekistan’s trade complementarity with the member states of the Eurasian Economic Union is distributed in food and live animals (SITC0), mineral fuels, lubricants and related materials (SITC3), manufactured goods classified chiefly by material (SITC6), commodities and transactions not classified elsewhere in the SITC (SITC9). Uzbekistan has strong trade complementarity with Armenia, Belarus and Kyrgyzstan, but weak trade complementarity with Russia and Kazakhstan.

ABSTRACT:A province wide prevalence study on multiple sclerosis (MS) was conducted in British Columbia (B.C.). The prevalence date was July 1, 1982. The major portion of this study was a review of all the files of neurologists practicing in B.C. as this was judged to be the most accurate source for identifying MS patients. 239,412 neurologists' files were hand searched by one researcher using modified Schumacher criteria for classification. Other sources used during the study for identifying MS patients were the MS Clinic, general practitioners, ophthalmologists, urologists, specialized facilities such as long term care facilities and rehabilitation centres, and patient self-referrals.A total of 4,620 non-duplicated cases were identified and classified. 4,112 of these (89%) were classified according to information contained in neurologists' records.The prevalence estimate for definite/probable MS in B.C. was 93.3/100,000 population. This increased to 130.5/100,000 population if possible MS and optic neuritis were also included. These rates are among the highest reported in Canada or elsewhere. The cooperation of B.C. neurologists made this study unique in its scope and accuracy of diagnosis.

Abstract:

AbstractBuilders of medical informatics applications need controlled medical vocabularies to support their applications and it is to their advantage to use available standards. In order to do so, however, these standards need to address the requirements of their intended users. Overthe past decade, medical informatics researchers have begun to articulate some of these requirements. This paper brings together some of the common themes which have been described, including: vocabulary content, concept orientation, concept permanence, nonsemantic concept identifiers, polyhierarchy, formal definitions, rejection of “not elsewhere classified” terms, multiple granularities, mUltiple consistent views, context representation, graceful evolution, and recognized redundancy. Standards developers are beginning to recognize and address these desiderata and adapt their offerings to meet them.

CO2-concentrating mechanisms based on active inorganic C influx across a membrane (or membranes) are widespread in aquatic phototrophs. They are apparently absent from, or poorly developed in, taxa such as bryophytes and freshwater red algae, but are retained in some terrestrial phototrophs, i.e., some lichens and free-living algae and cyanobacteria related to the lichen photobionts. The natural occurrence of CO2-concentrating mechanisms is negatively correlated with CO2 enrichment of aquatic habitats from respiration of organic C produced elsewhere and, less clearly, with low temperatures during the growing season, with low external pH, and with rapid water movement over the plant surface. Predictions based on laboratory data and on theoretical considerations as to the influence of light, nitrogen, and iron availability on the occurrence of CO2-concentrating mechanisms have yet to be rigorously tested in the field. The evolution of CO2-concentrating mechanisms is not well understood, but clearly the location of inorganic C pumps must have been influenced by successive symbiotic events. Increasing atmospheric CO2 levels, and other anthropogenic effects (acidification, eutrophication), may influence the selective advantage (or disadvantage) associated with possession of CO2-concentrating mechanisms in particular environments. Key words: bicarbonate, CO2-concentrating mechanisms, iron, light, nitrogen, unstirred layers.

Abstract:

This research investigated the students learning behavior during the Reading class. The aimed of this study was improving students’ on-task behavior using group discussion. Furthermore, this study reveals the students’ attitudes who mostly were not directing their eyes gaze at the teacher and the instructional activity. For instance, the students did not pay attention toward appropriate instructional material and they were looking elsewhere. Thus, that behave was classified as off-task. While On-task behavior was defined as activity that complied with instructions given by the teacher for that lesson. Based on the previous matter, the use of group discussion during the classroom activities is definitely a fascinating phenomenon that can improve their on-task behavior during the learning activities in the class, especially reading.

Abstract:

The exploration of chemosynthetic communities in the geologic record over the last ten years has generated a series of sedimentological, tectonic and geochemical criteria that help define a continuum of environments from hot hydrothermal vents to nearshore geothermal deposits. Many of these studies have used stable isotope geochemistry to uncover a depleted carbon signature that characterizes most fossil chemosynthetically derived deposits. Isotope geochemistry (carbon, nitrogen and sulfur) as been an important thread in the story of the discovery of modern chemosynthetic communities, as well, adding to understanding of the biogeochemistry of these ecosystems. With increasing awareness of the prominence of these communities, not just as a biological novelty, but as a fundamental component of life on Earth (and perhaps elsewhere), the drive to develop geochemical proxies for chemosynthetic taxa in the fossil record intensifies. Increased ability to recognize these communities provides access to a second tier of paleobiological questions, including ideas of evolutionary history and selective advantage.

Abstract:

AbstractThermometric and D-ICP analysis of fluid inclusions in calcite and fluorite show that the fluids responsible for extensive carbonate-hosted copper mineralization in the Ecton Hill area were low-temperature (< 100 °C), high-salinity (19.5 to 23 wt. % NaCl equivalents) brines strongly enriched in calcium (mean Ca:Na wt. ratio = 1.9). Compared with the fluids responsible for classical ‘Mississippi Valley type’ lead-zinc deposits elsewhere in the south Pennine orefield, the Ecton ore-fluids were of lower temperature and slightly more enriched in potassium. Despite these subtle differences, the data are consistent with a basinal brine model for ore genesis in this western part of the orefield similar to that envisaged for the remainder of the orefield. These Ca-Na-K-Cl, copper-bearing brines were most probably derived from the Cheshire basin located to the west of the Derbyshire Dome.

For those interested in shallow seismic reflection (SSR) techniques, this special issue of Geophysics is likely to serve as a useful reference for years to come. The idea for this issue grew out of discussions that took place at the Shallow Seismic Reflection Workshop at the Lawrence Berkeley Laboratory, California, in September 1996. The content of those discussions is the subject of a published report elsewhere (Steeples et al., 1997). Several workshop participants and their colleagues contributed to the papers in this issue as authors and as reviewers. The articles include case histories, novel uses of the SSR technique, state‐of‐the‐art planning considerations for 3-D SSR surveys, and some examples of problems unique to SSR surveying.

Abstract:

The evolution of tropical forest deforestation in Côte d'Ivoire is very alarming. From 16 million hectares in 1900, the area increased to 9 million hectares in 1965 to less than 2.5 million hectares in 2016. Even forests protected by the State of Côte d'Ivoire are not spared while peri-urban protected forests are the most exposed. The finding reveals many shortcomings in the state monopoly of protected area management. Yet, elsewhere in Africa, many experiences of participatory management have shown significant advances in protection and their introduction in Côte d'Ivoire from 1990. To understand the effectiveness of this new consultation framework adopted as a management tool, national policies and locally adopted strategies on the Mount Korhogo classified forest in northern Côte d'Ivoire have been analyzed. Results show a failure of participation at the national level since 1996 and a lack of participation at the local level. Despite the establishment of a local committee for forest defense and fight against bush fires, the lack of consultation undermines the proper functioning of this organization, thus leading to the exacerbation of deforestation.

Abstract:

AbstractSpinel lherzolite xenoliths from two localities in the Massif Central are undepleted in Al2O3, CaO, and Na2O. One suite from Tarreyres, is K2O depleted and amphibole-bearing whereas the other, from Monistrol d'Allier some 18 km away, is amphibole-free and has a higher mean K2O content of 0.035 wt.%. We present bulk major and minor element abundances in a harzburgite and a lherzolite from each locality and microprobe analyses of their constituent phases. Amphibole-bearing lherzolite and its pyroxenes are light-rare earth element (LREE) depleted, whereas amphibole-free lherzolite and its pyroxenes are LREE enriched. Both harzburgites and their pyroxenes are LREE enriched and one rock contains LREE enriched glass. The harzburgites are like harzburgite xenoliths from elsewhere but each lherzolite represents a previously unrecognized type of mantle in terms of the mineralogy and REE content. The implication for basalt genesis are briefly discussed.

Abstract:

During the Late Proterozoic a more than 1000 m thick succession of sediments was deposited on the shelf fringing the north-eastern corner of the Greenland craton. These sediments were classified together with an underlying turbidite sequence in the Hagen Fjord Group (Haller, 1961), which is here redefined to contain only Upper Proterozoic, mainly shallow marine shelf deposits outcropping between Independence Fjord and Kronprins Christian Land in eastern North Greenland. Both siliciclastic and carbonate sedimentation occurred during the Late Proterozoic, and the changing tectonic environment along the northern and eastern shelf-margin of Greenland at that time is well recorded within the sediment sequence. Correlation of the Hagen Fjord Group with similar shelf deposits elsewhere along the eastern and northern margin of the Canadian-Greenlandian Shield is discussed.

Abstract:

This paper outlines a diagnostic entity called ‘Pathological Habit Disorder’ which is suggested for inclusion in the DSM as an Axis II option. Specific areas of concern, either mental (Axis I) or physical (Axis III), would delineate the syndrome. Pathological Habit Disorder (PHD) points to treatment options where the syndrome is wholly or partly habit-driven. Whether the syndrome is habit-driven or not will remain a clinical judgement even though many conditions, previously thought immutable except by medication, are proving accessible to behavioural engineering. In the ICD system, PHD seems to fit in “Special Symptoms or Syndromes not elsewhere Classified”. It is demonstrably useful to have a diagnosis such as PHD and to incorporate it into the body of medical classification, recognizing current practices for dealing with unwelcome or damaging habits.

Abstract:

Abstract A topographical study of the electron momentum density (EMD) of some linear molecules is presented with special emphasis on the bond-directionality principle. A new approach to the bond-directionality (BD) principle has been proposed. This is based on the analysis of curvatures of critical points at p = 0 and elsewhere on the bonding axis. The linear molecules are classified into three broad categories: those which fully obey or disobey the BD principle as well as those which satisfy it only partly. The Laplacian of the EMD at p = 0 has been associated with the quality of the wavefunction via the electron density in the tail region. Also, the similarity in the critical structure of both the EMD and the spherically averaged EMD at the origin is brought out.

Abstract:

Abstract We describe a simplified liquid-chromatographic test in which acetylator phenotype is determined by measuring the peak height ratio of two urinary caffeine metabolites, 5-acetylamino-6-formylamino-3-methyluracil and 1-methylxanthine. We applied this test to determine the acetylator phenotypes of 52 subjects who regularly drink coffee, tea, or caffeinated beverages. Also, we determined the acetylator phenotypes of these subjects according to a well-established sulfasalazine test, which yielded identical results. We established the reproducibility of the described test by determining the acetylator phenotypes of 10 additional subjects on two different days separated by a period of two to five weeks. Of the 52 subjects examined by both tests, 40 (76.9%) were classified as slow acetylators, which agrees well with the percentage reported elsewhere for 297 similar subjects from the Saudi population.

Abstract:

SummaryThe family registration records from a village population in a small island of Japan are used to assess the effect of demographic differentiation within a population on genetic measures. When the couples studied are classified by birth cohorts and origins, wives of the couples where one spouse came from elsewhere were older at marriage and had a shorter duration of marriage or registration than wives where both spouses were natives of the village. The mean number of offspring is statistically smaller in the former except for the latest cohort, due mainly to out-migration during the reproductive ages which also resulted in low rates of marriage among the offspring within the village. This leads to a small effective population size and an increased likelihood of genetic drift in the overall population.

Abstract:

AbstractChromitite zones associated with ultramafic units of the Lysanskiy layered complex of dunite–peridotite–gabbro composition could well represent the primary source for the placers bearing platinum-group minerals (PGM) of the entire drainage of the River Sisim and its tributaries, the rivers Ko and Seyba, eastern Sayans. Alluvial gold present in the placers of River Seyba, as elsewhere in the Sisim Placer Zone, reflects mineralisation during a recent period of tectonic activity. We focus on the PGM in the Seyba suite, and in particular on the attributes of pentlandite enriched in platinum-group-elements (PGE) and the compositionally similar and recently defined ferhodsite, which were trapped in host grains of Os–Ir–Ru alloy. Both minerals formed from small volumes of fractionated Fe–Ni–Cu melt considerably enriched in the PGE. In the Seyba suite, as in several others, the amounts of PGE in ferhodsite exceeds that in pentlandite, which results in a greater proportion of vacancies than in pentlandite.

Full text

Abstract:

Abstract Reaction textures including corona structures in granulites from the Proterozoic Long Range Inlier of western Newfoundland are spatially associated with a Silurian (0.34 Ga) mafic intrusion, the Taylor Brook Gabbro Complex. They comprise, in metabasites and tonalitic gneiss, coronal orthopyroxene and plagioclase on garnet and, in metapelites, cordierite and spinel formed at the expense of sillimanite, garnet and quartz. Although generally interpreted to indicate near-isothermal decompression (ITD) following regional metamorphism, which in the inlier occurred at ˜1.10–1.03 Ga, these features appear to be absent elsewhere. Therefore they are interpreted to be products of contact metamorphism (near-isobaric heating – IBH) within the thermal aureole of the gabbro. Thus, there is a ˜0.7 Ga difference (i.e. mid-Proterozoic vs. mid-Silurian) between the age of the regional metamorphic mineral assemblages and the contact aureole assemblages. The observation that classic ITD features occur in this aureole environment underscores the fact that P-sensitive reactions can progress during IBH as well as by pressure release.

Abstract:

AbstractEndoskarns formed where a swarm of diorite dykes have intruded calcite marble at Redcap Creek include an inner melilite-dominated, a wollastonite-dominated, and an outer massive tilleyite zone in contact with marble. The massive tilleyite is unusual in that it is coarse-grained (prisms 2–15 cm in length) and its deep grey colour contrasts with the lighter coloured varieties described elsewhere. A chemical analysis gives a formula close to ideal, with only minor substitution of Al, Ti, and Mg. Refined unit cell parameters are in close agreement with those quoted in the literature. The skarns have clearly formed by transport of Si, Mg, Fe, Al, and Ti from the igneous rocks, and Ca in the reverse direction from the marble. Activity diagrams derived from experimental data are most useful in interpreting the zonal sequence of endoskarns, and preliminary results suggest mass transfer at low Xco2 and temperature of the order of 800°C or higher for the formation of the massive tilleyite.

The Mecsek Mts and the Villány Hills represent the most southern (low)mountain region of Hungary. Here 63 grasshopper species were detected (=51,6% of the total Hungarian Orthoptera fauna), however, several in Hungary elsewhere common species were not found. High percentage of some Mediterranean, Balkan and other, elsewhere in Hungary rare or missing Orthoptera species (as e.g. Poecilimon fussi, Poecilimon intermedius, Isophya costata, I. modestior, I. modesta, I. camptoxypha, Sagapedo, Odontopodisma decipiens, O. schmidtii, Aiolopus strepens, Acrotylus insubricus, etc.), are characteristic to this fauna and to these grasshopper assemblages. The joint and frequent occurrence of bigger, mostly predaceous decticines (3 Pholidoptera spp., Pachytrachis gracilis, Pterolepis germanica) is also remarkable. Species being under legislative nature protection in Hungary amounted to 10 taxons (=15,9 %) in the Mecsek, - among them with two sub-endemics for the Carpathian Basin: Isophya costata and /. camptoxypha. However, during the last decades some flightless phaneropterids (/. modesta, I. camptoxypha, I. modestior) seem to have suffered local extiction around settlements due to the urbanization pressure. Species occurring in the Mecsek Mts were classified according to their phenology. The northernmost sites of the area of Aiolopus strepens - the adults overwinter - were detected in the Mecsek. Places of occurrence of rare and protected species {Isophya spp., Poecilimon intermedius, Aiolopus strepens) are endangered by habitat destruction, especially around the city Pécs, that is extending to parts of the southern slopes of the Misina Mt (535 m).

Abstract:

In most areas of Australia, mammals constitute the staple diets of cats, foxes and dingoes. In central Australia the abundance of mammals is often too low to meet the dietary requirements of these carnivores and yet populations of cats, foxes and dingoes persist. To investigate alternative feeding strategies of cats, foxes and dingoes in arid environments, their diets were monitored in relation to prey availability in two areas of the Tanami Desert where rabbits do not occur. Dietary information was obtained by analysing predator scats collected between 1995 and 1997. Prey availability was monitored by track counts, pitfall trapping, Elliott trapping, and bird counts along walked transects. In contrast to dietary studies elsewhere in Australia, it was found that reptiles were an important component of the diets of predators in the Tanami Desert, and should be classified as seasonal staples. Birds increased in importance in the diets of cats and foxes during the winter, when reptiles were less active. There was considerable overlap between the diets of all three predators, although dingoes ate more large prey items (e.g.�macropods) than the other two predators. Results highlight the opportunistic feeding habits of cats, foxes and dingoes and show that, although mammalian prey are less important in central Australia than has been found elsewhere, species that are vulnerable to extinction, such as the bilby (Macrotis lagotis), mulgara (Dasycercus cristicauda) and marsupial mole (Notoryctes typhlops), are also consumed by these predators.

Abstract:

Energy storage is a key technology for many purposes and in particular for air conditioning plants and a successful exploitation of solar energy. Thermal storage devices are usually classified as either variable temperature (“sensible heat”) or constant temperature (“latent heat”) devices. For both models a basic question is to determine the efficiency suitably: Only exergy efficiency appears a proper way. The aim of this paper is to examine exergy efficiency in both variable and constant temperature systems. From a general statement of exergy efficiency by the present author, two types of actual definitions are proposed, depending on the fact that the exergy of the fluid leaving the thermal storage during the charge phase can be either totally lost or utilized elsewhere. In addition, specific remarks are made about the exergy of a system in a periodically varying temperature environment.

Abstract:

Analysis of partial hepatitis C virus sequences has revealed many novel genotype 6 variants that cannot be unambiguously classified, which obscure the distinctiveness of pre-existing subtypes. To explore this uncertainty, we obtained genomes of 98.0–98.8 % full-length for eight such variants (KM35, QC273, TV257, TV476, TV533, L349, QC271 and DH027) and characterized them using phylogenetic analyses and per cent nucleotide similarities. The former four are closely related phylogenetically to subtype 6k, TV533 and L349 to subtype 6l, QC271 to subtypes 6i and 6j, and DH027 to subtypes 6m and 6n. The former six defined a high-level grouping that comprised subtypes 6k and 6l, plus related strains. The threshold between intra- and inter-subtype diversity in this group was indistinct. We propose that similar results would be seen elsewhere if more intermediate variants like QC271 and DH027 were sampled.

Abstract:

AbstractIt is shown here that dyke rocks of type localities for ‘soda-minettes’ are not minettes (= lamprophyres dominated by phlogopite and K-rich feldspar). It has long been suggested that ‘soda-minette’ also be applied to otherwise normal minettes from elsewhere that carry modally variable amounts of groundmass aegirine and/or, more commonly, arfvedsonitic to riebeckitic amphibole. Despite the presence of sodic pyriboles, these rocks are poorer in Na2O then minettes lacking these phases. ‘Soda-minette’ is thus misleading and self-contradictory to the many petrologists to whom ‘soda-’ legitimately connotes that the rock in question either has K/Na < 1 and/or is rich in albitic feldspar. To eliminate this ambiguity it is recommended, with the approval of twenty-six other petrologists, that ‘soda-minette’ no longer be used as a rock name. As minettes with Na-pyribole(s) are markedly K-rich and most are both ultrapotassic and peralkaline, independent of the modal abundance of the Na-pyrobile, it is suggested that one of these three chemical characteristics be utilized adjectivally in naming these minettes.

Abstract:

AbstractMg-Mn amphibole (tirodite), with or without pyroxmangite in the total absence of pyroxenes and high-calcic pyroxenoids, occurs in the Mn silicate rocks of the Sausar Group, India. The rocks were metamorphosed to amphibolite facies condition (T ∼ 650°C, P ∼ 6 kbar). Tirodite-pyroxmangite pairs developed in both carbonate-free and rhodochrosite-bearing assemblages. Also tirodite coexists with either kutnahorite or manganoan calcite in the absence of pyroxmangite. Mineral reactions inferred from modal abundances and compositions of the phases indicate stabilization of the amphibole alone from a bivalent cation-bearing residual unbuffered XCO2 system with XMn < 0.3. On the other hand, tirodite-pyroxmangite pairs appeared in unbuffered low to intermediate XCO2 assemblages with XMn > 0.35. Pyroxenes and high-calcic pyroxenoids did not appear in the present situation, though they occur elsewhere in rocks with broadly similar contents of immobile components. Closely associated assemblages of diverse mineralogy suggest that the XMn and XCO2, rather than the physical conditions of metamorphism, are the decisive factors in promoting the observed phase assemblages.
