  4. A unified framework for producing CAI melting, Wark-Lovering rims and bowl-shaped CAIs

    Calcium-Aluminium inclusions (CAIs) formed in the Solar system, some 4567 million years ago. CAIs are almost always surrounded by Wark-Lovering rims (WLRs), which are a sequence of thin, mono/bi-mineralic layers of refractory minerals, with a total thickness in the range of 1-100 microns. Recently, some CAIs have been found that have tektite-like bowl-shapes. To form such shapes, the CAI must have travelled through a rarefied gas at hypersonic speeds. We show how CAIs may have been ejected from the inner solar accretion disc via the centrifugal interaction between the solar magnetosphere and the inner disc rim. They subsequently punched through the hot, inner disc rim wall at hypersonic speeds. This re-entry heating partially or completely evaporated the CAIs. Such evaporation could have significantly increased the metal abundances of the inner disc rim. High speed movement through the inner disc produced WLRs. To match the observed thickness of WLRs required metal abundances at the inner disc wall that are of order 10 times that of standard solar abundances. The CAIs cooled as they moved away from the protosun, the deduced CAI cooling rates are consistent with the CAI cooling rates obtained from experiment and observation. The speeds and gas densities required to form bowl-shaped CAIs are also consistent with the expected speeds and gas densities for larger, ˜1 cm, CAIs punching through an inner accretion disc wall.

    In this paper we present new and review already existing landslide and earthquake data for a large part of the Tien Shan, Central Asia. For the same area, only partial databases for sub-regions have been presented previously. They were compiled and new data were added to fill the gaps between the databases. Major new inputs are products of the Central Asia Seismic Risk Initiative (CASRI): a tentative digital map of active faults (even with indication of characteristic or possible maximum magnitude) and the earthquake catalogue of Central Asia until 2009 that was now updated with USGS data (to May 2014). The new compiled landslide inventory contains existing records of 1600 previously mapped mass movements and more than 1800 new landslide data. Considering presently available seismo-tectonic and landslide data, a target region of 1200 km (E-W) by 600 km (N-S) was defined for the production of more or less continuous geohazards information. This target region includes the entire Kyrgyz Tien Shan, the South-Western Tien Shan in Tajikistan, the Fergana Basin (Kyrgyzstan, Tajikistan and Uzbekistan) as well as the Western part in Uzbekistan, the North-Easternmost part in Kazakhstan and a small part of the Eastern Chinese Tien Shan (for the zones outside Kyrgyzstan and Tajikistan, only limited information was available and compiled). On the basis of the new landslide inventory and the updated earthquake catalogue, the link between landslide and earthquake activity is analysed. First, size-frequency relationships are studied for both types of geohazards, in terms of Gutenberg-Richter Law for the earthquakes and in terms of probability density function for the landslides. For several regions and major earthquake events, case histories are presented to outline further the close connection between earthquake and landslide hazards in the Tien Shan. From this study, we concluded first that a major hazard component is still now insufficiently known for both types of geohazards

    Data Systems Engineering Organization (DSEO) personnel developed a prototype computer aided instruction CAI system for the Naval Aviation Logistics Data Analysis (NALDA) system. The objective of this project was to provide a CAI prototype that could be used as an enhancement to existing NALDA training. The CAI prototype project was performed in phases. The task undertaken in Phase I was to analyze the problem and the alternative solutions and to develop a set of recommendations on how best to proceed. The findings from Phase I are documented in Recommended CAI Approach for the NALDA System (Duncan et al., 1987). In Phase II, a structured design and specifications were developed, and a prototype CAI system was created. A report, NALDA CAI Prototype: Phase II Final Report, was written to record the findings and results of Phase II. NALDA CAI: Recommendations for an Advanced Instructional Model, is comprised of related papers encompassing research on computer aided instruction CAI, newly developing training technologies, instructional systems development, and an Advanced Instructional Model. These topics were selected because of their relevancy to the CAI needs of NALDA. These papers provide general background information on various aspects of CAI and give a broad overview of new technologies and their impact on the future design and development of training programs.

    We have recently discovered the first well-preserved calcium aluminum-rich inclusion (CAI) in a CI1 chondrite (Ivuna). Previously, all CI1 chondrites were thought to be devoid of preserved CAI and chondrules due to the near total aqueous alteration to which their parent body (bodies) have been subjected. The CAI is roughly spherical, but with a slight teardrop geometry and a maximum diameter of 170 microns (fig. 1). It lacks any Wark-Lovering Rim. Incipient aqueous alteration, and probably shock, have rendered large portions of the CAI poorly crystalline. It is extremely fine-grained, with only a few grains exceeding 10 microns. We have performed electron microprobe analyses (EPMA), FEG-SEM imaging and element mapping, as well as electron back-scattered diffraction (EBSD) and synchrotron X-ray diffraction (SXRD) in order to determine the fundamental characteristics of this apparently unique object.

    SI-CAI hybrid combustion, also known as spark-assisted compression ignition (SACI), is a promising concept to extend the operating range of CAI (Controlled Auto-Ignition) and achieve the smooth transition between spark ignition (SI) and CAI in the gasoline engine. In this study, a SI-CAI hybrid combustion model (HCM) has been constructed on the basis of the 3-Zones Extended Coherent Flame Model (ECFM3Z). An ignition model is included to initiate the ECFM3Z calculation and induce the flame propagation. In order to precisely depict the subsequent auto-ignition process of the unburned fuel and air mixture independently after the initiation of flame propagation, the tabulated chemistry concept is adopted to describe the auto-ignition chemistry. The methodology for extracting tabulated parameters from the chemical kinetics calculations is developed so that both cool flame reactions and main auto-ignition combustion can be well captured under a wider range of thermodynamic conditions. The SI-CAI hybrid combustion model (HCM) is then applied in the three-dimensional computational fluid dynamics (3-D CFD) engine simulation. The simulation results are compared with the experimental data obtained from a single cylinder VVA engine. The detailed analysis of the simulations demonstrates that the SI-CAI hybrid combustion process is characterised with the early flame propagation and subsequent multi-site auto-ignition around the main flame front, which is consistent with the optical results reported by other researchers. Besides, the systematic study of the in-cylinder condition reveals the influence mechanism of the early flame propagation on the subsequent auto-ignition.

    The abundance of short-lived radionuclides (SLRs) in early solar system materials provide key information about their nucleosynthetic origin and can constrain the timing of early solar system events. Excesses of {sup 36}S ({sup 36}S*) correlated with {sup 35}Cl/{sup 34}S ratios provide direct evidence for in situ decay of {sup 36}Cl ({tau}{sub 1/2} {approx} 0.3 Ma) and have been reported in sodalite (Na{sub 8}Al{sub 6}Si{sub 6}O{sub 24}Cl{sub 2}) and wadalite (Ca{sub 6}Al{sub 5}Si{sub 2}O{sub 16}Cl{sub 3}) in CAIs and chondrules from the Allende and Ningqiang CV carbonaceous chondrites. While previous studies demonstrate unequivocally that {sup 36}Cl was extant in the early solar system, no consensus on the origin or initial abundance of {sup 36}Cl has emerged. Understanding the origin of {sup 36}Cl, as well as the reported variation in the initial {sup 36}Cl/{sup 35}Cl ratio, requires addressing when, where and how chlorine was incorporated into CAIs and chondrules. These factors are key to distinguishing between stellar nucleosynthesis or energetic particle irradiation for the origin of {sup 36}Cl. Wadalite is a chlorine-rich secondary mineral with structural and chemical affinities to grossular. The high chlorine ({approx}12 wt%) and very low sulfur content (<<0.01 wt%) make wadalite ideal for studies of the {sup 36}Cl-{sup 36}S system. Wadalite is present in Allende CAIs exclusively in the interior regions either in veins crosscutting melilite or in zones between melilite and anorthite associated with intergrowths of grossular, monticellite, and wollastonite. Wadalite and sodalite most likely resulted from open-system alteration of primary minerals with a chlorine-rich fluid phase. We recently reported large {sup 36}S* correlated with {sup 35}Cl/{sup 34}S in wadalite in Allende Type B CAI AJEF, yielding a ({sup 36}Cl/{sup 35}Cl){sub 0} ratio of (1.7 {+-} 0.3) x 10{sup -5}. This value is the highest reported {sup 36}Cl/{sup 35}Cl ratio and is {approx}5 times

  18. INVESTIGATION OF CRUSTAL MOTION IN THE TIEN SHAN USING INSAR

    Energy Technology Data Exchange (ETDEWEB)

    2011-02-25

    The northern Tien Shan of Central Asia is an area of active mid-continent deformation. Although far from a plate boundary, this region has experienced 5 earthquakes larger than magnitude 7 in the past century and includes one event that may as be as large as Mw 8.0. Previous studies based on GPS measurements indicate on the order of 23 mm/yr of shortening across the entire Tien Shan and up to 15 mm/year in the northern Tien Shan (Figure 1). The seismic moment release rate appears comparable with the geodetic measured slip, at least to first order, suggesting that geodetic rates can be considered a proxy for accumulation rates of stress for seismic hazard estimation. Interferometric synthetic aperture radar may provide a means to make detailed spatial measurements and hence in identifying block boundaries and assisting in seismic hazard. Therefore, we hoped to define block boundaries by direct measurement and by identifying and resolving earthquake slip. Due to political instability in Kyrgzystan, the existing seismic network has not performed as well as required to precisely determine earthquake hypocenters in remote areas and hence InSAR is highly useful. In this paper we present the result of three earthquake studies and show that InSAR is useful for refining locations of teleseismically located earthquakes. ALOS PALSAR data is used to investigate crustal motion in the Tien Shan mountains of Central Asia. As part of the work, considerable software development was undertaken to process PALSAR data. This software has been made freely available. Two damaging earthquakes have been imaged in the Tien Shan and the locations provided by ALOS InSAR have helped to refine seismological velocity models. A third earthquake south of Kyrgyzstan was also imaged. The use of InSAR data and especially L band is therefore very useful in providing groundtruth for earthquake locations.

  1. Surge-type glaciers in the Tien Shan (Central Asia)

    Surge-type glaciers in High Mountain Asia are mostly observed in Karakoram and Pamir. However, few surge-type glaciers also exist in the Tien Shan, but have not comprehensively studied in detail in the recent literature. We identified surge-type glaciers in the Tien Shan either from available literature or by manual interpretation using available satellite images (such as Corona, Hexagon, Landsat, SPOT, IRS) for the period 1960 to 2014. We identified 39 possible surge-type glaciers, showing typical characteristics like looped moraines. Twenty-two of them rapidly advanced during different periods or a surge was clearly described in the literature. For the remaining possible surge-type glaciers either the advance, in terms of time and length, were not mentioned in detail in the literature, or the glaciers have remained either stable or retreated during the entire period of our study. Most of the surge-type glaciers cluster in the Inner Tien Shan (especially in the Ak-Shiirak rage) and the Central Tien Shan, are in size and are facing North, West or North West. Pronounced surge events were observed for North Inylchek and Samoilowitsch glaciers, both of which are located in the Central Tien Shan. Samoilowitsch Glacier retreated by more than 3 km between 1960 (length ~8.9 km) and 1992 (~5.8 km), advanced by almost 3 km until 2006 and slightly retreated thereafter. The most pronounced advance occurred between 2000 and 2002. DEM differencing (based on SRTM3 data and stereo Hexagon and Cartosat-1 data) revealed a significant thickening in the middle reaches (reservoir area) of the glacier between 1973 and 2000 while the surface significantly lowered in the middle and upper parts of the glacier between 2000 and 2006. Hence, the ice mass was transferred to the lower reaches (receiving area) and caused the advance with a maximum thickening of more than 80 m. The ~30 km long North Inylchek Glacier retreated since 1943 and showed a very rapid advance of ~3.5 km especially in

  2. Silicon Isotopic Fractionation of CAI-like Vacuum Evaporation Residues

    Calcium-, aluminum-rich inclusions (CAIs) are often enriched in the heavy isotopes of magnesium and silicon relative to bulk solar system materials. It is likely that these isotopic enrichments resulted from evaporative mass loss of magnesium and silicon from early solar system condensates while they were molten during one or more high-temperature reheating events. Quantitative interpretation of these enrichments requires laboratory determinations of the evaporation kinetics and associated isotopic fractionation effects for these elements. The experimental data for the kinetics of evaporation of magnesium and silicon and the evaporative isotopic fractionation of magnesium is reasonably complete for Type B CAI liquids (Richter et al., 2002, 2007a). However, the isotopic fractionation factor for silicon evaporating from such liquids has not been as extensively studied. Here we report new ion microprobe silicon isotopic measurements of residual glass from partial evaporation of Type B CAI liquids into vacuum. The silicon isotopic fractionation is reported as a kinetic fractionation factor, {alpha}{sub Si}, corresponding to the ratio of the silicon isotopic composition of the evaporation flux to that of the residual silicate liquid. For CAI-like melts, we find that {alpha}{sub Si} = 0.98985 {+-} 0.00044 (2{sigma}) for {sup 29}Si/{sup 28}Si with no resolvable variation with temperature over the temperature range of the experiments, 1600-1900 C. This value is different from what has been reported for evaporation of liquid Mg{sub 2}SiO{sub 4} (Davis et al., 1990) and of a melt with CI chondritic proportions of the major elements (Wang et al., 2001). There appears to be some compositional control on {alpha}{sub Si}, whereas no compositional effects have been reported for {alpha}{sub Mg}. We use the values of {alpha}Si and {alpha}Mg, to calculate the chemical compositions of the unevaporated precursors of a number of isotopically fractionated CAIs from CV chondrites whose

  3. Spectral Analysis of Broadband Seismic Array Data, Tien Shan

    We used a spectral analysis method to examine amplitude variations of body waves recorded in the Tien Shan region of central Asia. We used broadband data from the Kyrgyz Network (KNET), Kazakhstan Network (KZNET), and from a set of temporary, PASSCAL stations operated from 1997-2000 we refer to as the Ghengis array. A spectral ratio method similar to that used by Wilson and Pavlis (2000) was employed, but with station AAK used as a reference instead of the array median. Spectral ratios were estimated for all teleseismic events and a larger, intermediate depth events from the Hindu-Kush region for all three-components of ground motion and total signal strength on all components. Results are visualized by maps of amplitude for various frequency bands and through the 4-D animation method introduced by Wilson and Pavlis (2000). Data from Hindu-Kush events showed amplitude variations as much as a factor of 100 across the study area with a strong frequency dependence. The largest variations were at the highest frequencies observed near 15 Hz. Stations in the northwestern part of the Tien Shan array show little variation in amplitude relative to the reference station, AAK. In the central and eastern part of the array, the amplitude estimates are significantly smaller at all frequencies. In contrast, for stations in the western Tien Shan near the Talas-Fergana Fault, and the southern Tien Shan near the Tarim Basin, the amplitude values become much larger than the reference site. The teleseismic data show a different pattern and show a somewhat smaller, overall amplitude variation at comparable frequencies. The northern part of the array again shows small variations relative to the reference stations. There are some amplifications in the southern stations of the array, especially in the Tarim Basin. The higher frequency observations that show large amplifications at stations in the Tarim Basin are readily explained by site effects due to the thick deposits of sediments

    Vibrio cholerae, the bacterium that causes the disease cholera, controls virulence factor production and biofilm development in response to two extracellular quorum-sensing molecules, called autoinducers. The strongest autoinducer, called CAI-1 (for cholera autoinducer-1), was previously identified as (S)-3-hydroxytridecan-4-one. Biosynthesis of CAI-1 requires the enzyme CqsA. Here, we determine the CqsA reaction mechanism, identify the CqsA substrates as (S)-2-aminobutyrate and decanoyl coenzyme A, and demonstrate that the product of the reaction is 3-aminotridecan-4-one, dubbed amino-CAI-1. CqsA produces amino-CAI-1 by a pyridoxal phosphate-dependent acyl-CoA transferase reaction. Amino-CAI-1 is converted to CAI-1 in a subsequent step via a CqsA-independent mechanism. Consistent with this, we find cells release {ge}100 times more CAI-1 than amino-CAI-1. Nonetheless, V. cholerae responds to amino-CAI-1 as well as CAI-1, whereas other CAI-1 variants do not elicit a quorum-sensing response. Thus, both CAI-1 and amino-CAI-1 have potential as lead molecules in the development of an anticholera treatment.

    Full Text Available El marketing esencial se basa en la determinación de los significados en la mente del consumidor y de los códigos en la mente del mercado. Para poder sustentar esto se han creado metodologías como las técnicas de afloramiento de significado y las técnicas proyectivas entre otras. Pero, el nuevo problema que surge de esta conceptualización teórica es si vamos a poner al significado en la base del plan de marketing, la pregunta es ¿cuántos significados se deben determinar? Por lo que sabemos cada cultura tiene sus propias significaciones y los significados también cambian con el tiempo incluso lo hacen contextualmente. Lo cual hace aún más complejo el dilema presentado como título de este artículo. En se presentan los argumentos teóricos que sustentan uno de los descubrimientos más importantes del marketing esencial que sostenemos: en general para cada producto o servicio hay cuatro significados dominantes.

    Full Text Available Abstract Background The objective of this study was to test the hypothesis that personality preference, which can be related to learning style, influences individual utilization of CAI applications developed specifically for the undergraduate medical curriculum. Methods Personality preferences of students were obtained using the Myers-Briggs Type Indicator (MBTI test. CAI utilization for individual students was collected from entry logs for two different web-based applications (a discussion forum and a tutorial used in the basic science course on human anatomy. Individual login data were sorted by personality preference and the data statistically analyzed by 2-way mixed ANOVA and correlation. Results There was a wide discrepancy in the level and pattern of student use of both CAI. Although individual use of both CAI was positively correlated irrespective of MBTI preference, students with a "Sensing" preference tended to use both CAI applications more than the "iNtuitives". Differences in the level of use of these CAI applications (i.e., higher use of discussion forum vs. a tutorial were also found for the "Perceiving/Judging" dimension. Conclusion We conclude that personality/learning preferences of individual students influence their use of CAI in the medical curriculum.

    Glacier retreat in high mountain areas around the world is considered one of the major geosciences research topics of last decades. This process may result in formation and further development of glacial lakes that are often unstable and pose a threat to downstream valleys. The studied area is situated at the end of a tributary valley on the northern side of Kyrgyz range, about 40 km south of the capital - Bishkek. Glaciers of Central Tien Shan are considered very sensitive indicators of climate change. The studied lake is part of a system of young lakes situated near the front of a retreating glacier therefore it ranks among potentially dangerous ones. The area is closely observed, terrain research including bathymetric, geophysical, geodetic measurements was carried out during last ten years. The lake level and its dependence on the changing climatic conditions in the area have been monitored in detail at this location since August 2007. Data from two meteorological stations are used to explain lake water level fluctuations, especially during ablation season when the lake is drained by a surface channel. The hydrological regime of the lake is compared with a regime of glacial streams, individual factors that affect it are described and possible trends and uncertainties that arise from it are analysed. The lake is also drained by subsurface channels, and as the water level declines over the cold part of a year, their capacity is studied and compared among years. The main aim of the study is to explain any deviations or changes found in the hydrological regime of the lake and to decide whether their cause could mean a decreased stability of the lake dam. Part of the dam is made up of moraine with buried ice and as the lake is drained by subsurface channels, their capacity can be changed due to moraine subsidence when the ice melts. This may lead either to sudden enlargement of channels' capacity or to their blockage, both of which could cause lake outburst.

    Ca, Al-rich inclusions (CAIs) often contain numerous refractory metal nuggets (RMNs), consisting of elements like Os, Ir, Mo, Pt and Ru. The nuggets are usually thought to have formed by equilibrium condensation from a gas of solar composition, simultaneously with or prior to oxide and silicate minerals. However, the exact mechanisms responsible for their extremely variable compositions, small sizes and associations with CAI minerals remain puzzling. Expanding on previous work on chemically separated RMNs, we have studied a large number of RMNs within their host CAIs from three different meteorite types, i.e., the highly primitive chondrite Acfer 094 (C2-ungrouped), Allende (CV3ox) and Murchison (CM2). Our results show several inconsistencies between the observed features and a direct condensation origin, including a lack of correlated abundance variations in the refractory metals that are expected from variations in condensation temperature. Instead, we show that most RMN features are consistent with RMN formation by precipitation from a CAI liquid enriched in refractory metals. This scenario is additionally supported by the common occurrence of RMNs in CAIs with clear melt crystallization textures as well as the occurrence of synthetic RMNs with highly variable compositions in run products from Schwander et al. (2015). In some cases, the sizes of meteoritic RMNs correlate with the sizes of their host minerals in CAIs, which indicates common cooling rates.

    Examination of >200 comet Wild 2 particles collected by the Stardust (SD) mission shows that the CAI abundance of comet Wild 2's rocky material is near 1% and that nearly 50% of all bulbous tracks will contain at least one recognizable CAI fragment. A similar abundance to Wild 2 is found in a giant cluster IDP thought to be of cometary origin. The properties of these CAIs and their comparison with meteoritic CAIs provide important clues on the role of CAIs in the early Solar System (SS) and how they were transported to the edge of the solar nebula where Kuiper Belt comets formed. Previously, only two CAIs in comet Wild 2 had been identified and studied in detail. Here we present 2 new Wild 2 CAIs and 2 from a giant cluster cometary IDP, describe their mineralogical characteristics and show that they are most analogous to nodules in spinel-rich, fine-grained inclusions (FGIs) observed in CV3 and other chondrites. Additionally, we present new O isotope measurements from one CAI from comet Wild 2 and show that its oxygen isotopic composition is similar to some FGIs. This is only the second CAI from Wild 2 in which O isotopes have been measured.

    Calcium-aluminum-rich inclusions (CAIs) are a type of coarse-grained clast composed of Ca-, Al-, and Mg-rich silicates and oxides found in chondrite meteorites. Type B (CAIs) are exclusively found in the CV chondrite meteorites and are the most well studied type of inclusion found in chondritic meteorites. Type B1 CAIs are distinguished by a nearly monomineralic rim of melilite that surrounds an interior predominantly composed of melilite, fassaite (Ti and Al-rich clinopyroxene), anorthite, and spinel with varying amounts of other minor primary and secondary phases. The formation of Type B CAIs has received considerable attention in the course of CAI research and quantitative models, experimental results and observations from Type B inclusions remain largely in disagreement. Recent experimental results and quantitative models have shown that the formation of B1 mantles could have occurred by the evaporative loss of Si and Mg during the crystallization of these objects. However, comparative studies suggest that the lower bulk SiO2 compositions in B1s result in more prior melilite crystallization before the onset of fassaite and anorthite crystallization leading to the formation of thick melilite rich rims in B1 inclusions. Detailed petrographic and cosmochemical studies of these inclusions will further our understanding of these complex objects.

  3. Arginine oscillation explains Na+ independence in the substrate/product antiporter CaiT.

    Most secondary-active transporters transport their substrates using an electrochemical ion gradient. In contrast, the carnitine transporter (CaiT) is an ion-independent, l-carnitine/γ-butyrobetaine antiporter belonging to the betaine/carnitine/choline transporter family of secondary transporters. Recently determined crystal structures of CaiT from Escherichia coli and Proteus mirabilis revealed an inverted five-transmembrane-helix repeat similar to that in the amino acid/Na(+) symporter LeuT. The ion independence of CaiT makes it unique in this family. Here we show that mutations of arginine 262 (R262) make CaiT Na(+)-dependent. The transport activity of R262 mutants increased by 30-40% in the presence of a membrane potential, indicating substrate/Na(+) cotransport. Structural and biochemical characterization revealed that R262 plays a crucial role in substrate binding by stabilizing the partly unwound TM1' helix. Modeling CaiT from P. mirabilis in the outward-open and closed states on the corresponding structures of the related symporter BetP reveals alternating orientations of the buried R262 sidechain, which mimic sodium binding and unbinding in the Na(+)-coupled substrate symporters. We propose that a similar mechanism is operative in other Na(+)/H(+)-independent transporters, in which a positively charged amino acid replaces the cotransported cation. The oscillation of the R262 sidechain in CaiT indicates how a positive charge triggers the change between outward-open and inward-open conformations as a unifying critical step in LeuT-type transporters.

    In order to cultivate plants under low pressure in closed environment, the germination rate of seeds of white radish was investigated under low pressure, low oxygen partial pressure and condition of pure oxygen. The result of these experiments showed that the germination rate was affected by the oxygen partial pressure. From this fact, it is possible to lower the total pressure by using only the pure oxygen in germination. Furthermore, the germination rates of seeds of buckwheat and qing-geng-cai were also investigated in pure oxygen for the comparison. Consequently, though tendency in germination rate of white radish was similar to qing-geng-cai, it was different from buckwheat.

    Detailed petrologic, geochemical and isotopic analyses of a new FUN CAI from the Allende CV3 meteorite (designated CMS-1) indicate that it formed by extensive melting and evaporation of primitive precursor material(s). The precursor material(s) condensed in a 16O-rich region (δ17O and δ18O ∼ -49‰) of the inner solar nebula dominated by gas of solar composition at total pressures of ∼10-3-10-6 bar. Subsequent melting of the precursor material(s) was accompanied by evaporative loss of magnesium, silicon and oxygen resulting in large mass-dependent isotope fractionations in these elements (δ25Mg = 30.71-39.26‰, δ29Si = 14.98-16.65‰, and δ18O = -41.57 to -15.50‰). This evaporative loss resulted in a bulk composition similar to that of compact Type A and Type B CAIs, but very distinct from the composition of the original precursor condensate(s). Kinetic fractionation factors and the measured mass-dependent fractionation of silicon and magnesium in CMS-1 suggest that ∼80% of the silicon and ∼85% of the magnesium were lost from its precursor material(s) through evaporative processes. These results suggest that the precursor material(s) of normal and FUN CAIs condensed in similar environments, but subsequently evolved under vastly different conditions such as total gas pressure. The chemical and isotopic differences between normal and FUN CAIs could be explained by sorting of early solar system materials into distinct physical and chemical regimes, in conjunction with discrete heating events, within the protoplanetary disk.

    The perception of gender development of individuals with complete androgen insensitivity syndrome (CAIS) as unambiguously female has recently been challenged in both qualitative data and case reports of male gender identity. The aim of the mixed-method study presented was to examine the self-perception of CAIS individuals regarding different aspects of gender and to identify commonalities and differences in comparison with subfertile and infertile XX-chromosomal women with diagnoses of Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) and polycystic ovary syndrome (PCOS). The study sample comprised 11 participants with CAIS, 49 with MRKHS, and 55 with PCOS. Gender identity was assessed by means of a multidimensional instrument, which showed significant differences between the CAIS group and the XX-chromosomal women. Other-than-female gender roles and neither-female-nor-male sexes/genders were reported only by individuals with CAIS. The percentage with a not exclusively androphile sexual orientation was unexceptionally high in the CAIS group compared to the prevalence in "normative" women and the clinical groups. The findings support the assumption made by Meyer-Bahlburg ( 2010 ) that gender outcome in people with CAIS is more variable than generally stated. Parents and professionals should thus be open to courses of gender development other than typically female in individuals with CAIS.

    Grown in arid regions of western China the cyanobacterium Nostoc flagelliforme--called fa cai in Mandarin and fat choy in Cantonese--is wild-harvested and used to make soup consumed during New Year's celebrations. High prices, up to $125 USD/kg, led to overharvesting in Inner Mongolia, Ningxia, Gansu, Qinghai, and Xinjiang. Degradation of arid ecosystems, desertification, and conflicts between Nostoc harvesters and Mongol herdsmen concerned the Chinese environmental authorities, leading to a government ban of Nostoc commerce. This ban stimulated increased marketing of a substitute made from starch. We analysed samples purchased throughout China as well as in Chinese markets in the United States and the United Kingdom. Some were counterfeits consisting of dyed starch noodles. A few samples from California contained Nostoc flagelliforme but were adulterated with starch noodles. Other samples, including those from the United Kingdom, consisted of pure Nostoc flagelliforme. A recent survey of markets in Cheng Du showed no real Nostoc flagelliforme to be marketed. Real and artificial fa cai differ in the presence of beta-N-methylamino-L-alanine (BMAA). Given its status as a high-priced luxury food, the government ban on collection and marketing, and the replacement of real fa cai with starch substitutes consumed only on special occasions, it is anticipated that dietary exposure to BMAA from fa cai will be reduced in the future in China.

    2013-09-01

    Full Text Available This review focuses on the role of OMICs technologies, concentrating in particular on proteomics, in biomarker discovery in chronic allograft injury (CAI. CAI is the second most prevalent cause of allograft dysfunction and loss in the first decade post-transplantation, after death with functioning graft (DWFG. The term CAI, sometimes referred to as chronic allograft nephropathy (CAN, describes the deterioration of renal allograft function and structure as a result of immunological processes (chronic antibody-mediated rejection, and other non-immunological factors such as calcineurin inhibitor (CNI induced nephrotoxicity, hypertension and infection. Current methods for assessing allograft function are costly, insensitive and invasive; traditional kidney function measurements such as serum creatinine and glomerular filtration rate (GFR display poor predictive abilities, while the current “gold-standard” involving histological diagnosis with a renal biopsy presents its own inherent risks to the overall health of the allograft. As early as two years post-transplantation, protocol biopsies have shown more than 50% of allograft recipients have mild CAN; ten years post-transplantation more than 50% of the allograft recipients have progressed to severe CAN which is associated with diminishing graft function. Thus, there is a growing medical requirement for minimally invasive biomarkers capable of identifying the early stages of the disease which would allow for timely intervention. Proteomics involves the study of the expression, localization, function and interaction of the proteome. Proteomic technologies may be powerful tools used to identify novel biomarkers which would predict CAI in susceptible individuals. In this paper we will review the use of proteomics in the elucidation of novel predictive biomarkers of CAI in clinical, animal and in vitro studies.

    The cost of alternative communications networks for the dissemination of PLATO IV computer-aided instruction (CAI) was studied. Four communication techniques are compared: leased telephone lines, satellite communication, UHF TV, and low-power microwave radio. For each network design, costs per student contact hour are computed. These costs are derived as functions of student population density, a parameter which can be calculated from census data for one potential market for CAI, the public primary and secondary schools. Calculating costs in this way allows one to determine which of the four communications alternatives can serve this market least expensively for any given area in the U.S. The analysis indicates that radio distribution techniques are cost optimum over a wide range of conditions.

    This paper is focused on the CAI combustion control in a turbocharged 2-stroke Opposed-Piston (OP) engine. The barrel type OP engine arrangement is of particular interest for the authors because of its robust design, high mechanical efficiency and relatively easy incorporation of a Variable Compression Ratio (VCR). The other advantage of such design is that combustion chamber is formed between two moving pistons - there is no additional cylinder head to be cooled which directly results in an increased thermal efficiency. Furthermore, engine operation in a Controlled Auto-Ignition (CAI) mode at high compression ratios (CR) raises a possibility of reaching even higher efficiencies and very low emissions. In order to control CAI combustion such measures as VCR and water injection were considered for indirect ignition timing control. Numerical simulations of the scavenging and combustion processes were performed with the 3D CFD multipurpose AVL Fire solver. Numerous cases were calculated with different engine compression ratios and different amounts of directly and indirectly injected water. The influence of the VCR and water injection on the ignition timing and engine performance was determined and their application in the real engine was discussed.

    In this report, we summarize what we have accomplished with five years of funding from NASA under its DOSE program, and with a comparable level of funding from NSF. We describe the development of a GPS network in the Tien Shan of Kyrgyzstan and Kazakhstan of the former Soviet Union, the analysis of data, and the main results. This discussion presents the state of the current network, which has grown significantly since the termination of our DOSE grants, with continued support both from NSF through its continental dynamics program and from NASA's SENH program. Although grants from NASA's DOSE program did not support this growth not directly, it did so indirectly by building the infrastructure that has enabled further expansion in an area where otherwise there would be only a small GPS presence. We note how the network has grown over time, but the emphasis of this discussion is on the quantity and quality of measurements that we have made.

  8. Source processes of strong earthquakes in the North Tien-Shan region

    Tien-Shan region attracts attention of scientists worldwide due to its complexity and tectonic uniqueness. A series of very strong destructive earthquakes occurred in Tien-Shan at the turn of XIX and XX centuries. Such large intraplate earthquakes are rare in seismology, which increases the interest in the Tien-Shan region. The presented study focuses on the source processes of large earthquakes in Tien-Shan. The amount of seismic data is limited for those early times. In 1889, when a major earthquake has occurred in Tien-Shan, seismic instruments were installed in very few locations in the world and these analog records did not survive till nowadays. Although around a hundred seismic stations were operating at the beginning of XIX century worldwide, it is not always possible to get high quality analog seismograms. Digitizing seismograms is a very important step in the work with analog seismic records. While working with historical seismic records one has to take into account all the aspects and uncertainties of manual digitizing and the lack of accurate timing and instrument characteristics. In this study, we develop an easy-to-handle and fast digitization program on the basis of already existing software which allows to speed up digitizing process and to account for all the recoding system uncertainties. Owing to the lack of absolute timing for the historical earthquakes (due to the absence of a universal clock at that time), we used time differences between P and S phases to relocate the earthquakes in North Tien-Shan and the body-wave amplitudes to estimate their magnitudes. Combining our results with geological data, five earthquakes in North Tien-Shan were precisely relocated. The digitizing of records can introduce steps into the seismograms which makes restitution (removal of instrument response) undesirable. To avoid the restitution, we simulated historic seismograph recordings with given values for damping and free period of the respective instrument and

    Focused ion beam (FIB) sectioning has revolutionized preparation of meteorite samples for characterization by analytical transmission electron microscopy (TEM) and other techniques. Although FIB is not "non-destructive" in the purest sense, each extracted section amounts to no more than nanograms (approximately 500 cubic microns) removed intact from locations precisely controlled by SEM imaging and analysis. Physical alteration of surrounding material by ion damage, fracture or sputter contamination effects is localized to within a few micrometers around the lift-out point. This leaves adjacent material intact for coordinate geochemical analysis by SIMS, microdrill extraction/TIMS and other techniques. After lift out, FIB sections can be quantitatively analyzed by electron microprobe prior to final thinning, synchrotron x-ray techniques, and by the full range of state-of-the-art analytical field-emission scanning transmission electron microscope (FE-STEM) techniques once thinning is complete. Multiple meteorite studies supported by FIB/FE-STEM are currently underway at NASA-JSC, including coordinated analysis of refractory phase assemblages in CAIs and fine-grained matrices in carbonaceous chondrites. FIB sectioning of CAIs has uncovered epitaxial and other overgrowth relations between corundum-hibonite-spinel consistent with hibonite preceding corundum and/or spinel in non-equilibrium condensation sequences at combinations of higher gas pressures, dust-gas enrichments or significant nebular transport. For all of these cases, the ability of FIB to allow for coordination with spatially-associated isotopic data by SIMS provides immense value for constraining the formation scenarios of the particular CAI assemblage. For carbonaceous chondrites matrix material, FIB has allowed us to obtain intact continuous sections of the immediate outer surface of Murchison (CM2) after it has been experimentally ion processed to simulate solar wind space weathering.

    The high time resolution Pb-Pb ages and short-lived nuclide based relative ages for CAIs and chondrules are reviewed. The solar system started at 4567.2 {+-} 0.6Ma inferred from the high precision Pb-Pb ages of CAIs. Time scales of CAIs ({le}0.1Myr), chondrules (1-3Myr), and early asteroidal differentiation ({ge}3Myr) inferred from {sup 26}Al relative ages are comparable to the time scale estimated from astronomical observations of young star; proto star, classical T Tauri star and week-lined T Tauri star, respectively. Pb-Pb ages of chondrules also indicate chondrule formation occur within 1-3 Myr after CAIs. Mn-Cr isochron ages of chondrules are similar to or within 2 Myr after CAI formation. Chondrules from different classes of chondrites show the same range of {sup 26}Al ages in spite of their different oxygen isotopes, indicating that chondrule formed in the localized environment. The {sup 26}Al ages of chondrules in each chondrite class show a hint of correlation with their chemical compositions, which implies the process of elemental fractionation during chondrule formation events.

  14. New Evidence for 26Al in CAI and Chondrules from Type 3 Ordinary Chondrites

    We have known since 1976 that 26A1 (tl/2 = 7.2 x 105 yrs) was alive in the early solar system, at a level of (26Al/27Al)o z 5 x 10-5 in calcium-aluminum inclusions (CAI). However, several outstanding questions remain. Little evidence for 26A1 has been found in other chondritic material, and none has been found in differentiated meteorites. These results might imply that 26A1 was heterogeneously distributed in the nebula or by mineralogic site in nebular dust, or they might reflect differences in time of formation. There are strict limitations on finding evidence of 26A1 in normal chondrules with bulk Al/Mg ~ 0.1, since even quenched, perfectly preserved, late-stage glasses would have low Al/Mg. Primary plagioclase crystals provide the only possibility, but these only crystallize rarely in melts within the compositional range of normal chondrules. Also, metamorphism can erase the evidence in high-AI/Mg phases. To address these issues, we have conducted a search for chondrules and CAI with high-Al/Mg phases suitable for ion-probe measurement in type 3 ordinary chondrites. Previous work has revealed evidence for 26Al in a plagioclase bearing, olivine-pyroxene class from Semarkona (LL3.0; (26Al/27Al)o = 7.7+/-2.1 x 10-6)), a plagioclase-rich object from Bovedy (L3.7?; 2.5+/-1.2 x 10-7), in separated plagioclase from St. Marguerite (H4; 2.0+/-0.6 x 10-7), an isolated hibonite grain from Dhajala (H3.8; 8.4+0.5 x 10-6), and in Al2O3 and hibonite grains ((26Al/27Al)o = 2-5 x 10-5; [GRH, unpublished]) from acid residues of Semarkona, Bishunpur (LL3.1), and Krymka (LL3.1). We have identified and measured Al-Mg isotope systematics in two CAI and seven chondrules from ordinary chondrites of low metamorphic grade and have found clear evidence for 26A1 in both CAI and in two chondrules.

  20. Ca-Fe and Alkali-Halide Alteration of an Allende Type B CAI: Aqueous Alteration in Nebular or Asteroidal Settings

    2012-01-01

    Ca-Fe and alkali-halide alteration of CAIs is often attributed to aqueous alteration by fluids circulating on asteroidal parent bodies after the various chondritic components have been assembled, although debate continues about the roles of asteroidal vs. nebular modification processes [1-7]. Here we report de-tailed observations of alteration products in a large Type B2 CAI, TS4 from Allende, one of the oxidized subgroup of CV3s, and propose a speculative model for aqueous alteration of CAIs in a nebular setting. Ca-Fe alteration in this CAI consists predominantly of end-member hedenbergite, end-member andradite, and compositionally variable, magnesian high-Ca pyroxene. These phases are strongly concentrated in an unusual "nodule" enclosed within the interior of the CAI (Fig. 1). The Ca, Fe-rich nodule superficially resembles a clast that pre-dated and was engulfed by the CAI, but closer inspection shows that relic spinel grains are enclosed in the nodule, and corroded CAI primary phases interfinger with the Fe-rich phases at the nodule s margins. This CAI also contains abundant sodalite and nepheline (alkali-halide) alteration that occurs around the rims of the CAI, but also penetrates more deeply into the CAI. The two types of alteration (Ca-Fe and alkali-halide) are adjacent, and very fine-grained Fe-rich phases are associated with sodalite-rich regions. Both types of alteration appear to be replacive; if that is true, it would require substantial introduction of Fe, and transport of elements (Ti, Al and Mg) out of the nodule, and introduction of Na and Cl into alkali-halide rich zones. Parts of the CAI have been extensively metasomatized.

    Well-preserved flights of river and lake terraces traverse an actively deforming rangefront, and form a link between glaciated mountains and a large intermontane lake in the Issyk-Kul basin of the Kyrgyz Tien Shan. We investigated the history and geometry of these lake and river terraces using geologic mapping, surveying, and radiocarbon and terrestrial cosmogenic nuclide dating. A prominent late Pleistocene highstand of the lake occurred over at least the period of 43-25 ka, followed by a period of deep regression and subsequent rise of the lake to the modern sill level in the late Holocene. Major aggradation of the most prominent latest Quaternary river terrace along the Ak-Terek and Barskaun rivers likely started at ∼70-60 ka, coincident to the local last glacial maximum in this region. In contrast to some models of aggradation and incision, the rivers appear to have stayed near the top of the fill for >20 ka, incising subtly below the top of this fill by ∼37 ka, locally. Deep incision likely did not occur until the peak deglaciation in the latest Pleistocene. Older dated terrace surfaces are consistent with one major terrace-forming event per glacial, constant deformation and incision rates, and typical fluvial gradients lower than the modern incising streams. The dating confirms regional terrace correlations for the most prominent late Quaternary terraces, but correlating higher terraces is complicated by spatially varying uplift rates and preferential terrace preservation between basins in the Tien Shan.

  6. Climatic vs. Seismic Controlled Rockglacier Advances in Northern Tien Shan - Insights from Lichenometry

    Glaciers and permafrost landforms in high mountain areas are of major importance for storing and providing fresh water for the surroundings, especially in arid or semi-arid areas as Central Asia. Rockglaciers have been traditionally used as landform proxies of the distribution of alpine permafrost. In the northern Tien Shan mountains, the most distinct lobes of >200 rockglaciers that we mapped from satellite imagery occur at minimum elevations between 2500 and 3700 m. However, individual and particularly low-lying lobes extend down to well below 3000 m, and seem difficult to reconcile with regional paleoclimatic fluctuations. To support ground based and satellite imagery estimates on rockglacier advances (1 to 10 m/yr) and to gain information on their morphological characteristics, we present results of terrestrial LiDAR measurements on six rockglaciers in four steep mountain valleys in the Kyrgyz and Kazakh Tien Shan. Having the ability to destabilize, and thus provide massive sediment input from hillslopes, we hypothesize that strong earthquakes may also have influenced the formation or advance of some of the region's rockglaciers. This hypothesis is based on the observation that the tectonically active area was affected by a series of major earthquakes in the late 19th and earliest 20th centuries, which have subsequently triggered numerous landslides and rock falls. Using lichenometry, we aim to resolve age patterns on lobes of different rockglaciers located both, in the vicinity and distal from large young historic earthquakes. This method has been used successfully to reconstruct glaciation histories, and paleoseismicity. To gain information about and to compare advance histories of the rockglaciers from the relative ages of their lobes, we compiled a dataset of several thousand lichen diameter measurements of different species (e.g., Rhizocarpon geographicum, Aspicilia tianshanica, Lecanora muralis, and Xanthoria elegans). Results show that lichen age

The results of the examination indicate that north-south shortening is presently occurring in the Tien Shan, with the formation of basement uplifts flanked by moderately dipping thrust faults. The present-day tectonics of the Tien Shan seem to be analogous to those of the Rocky Mountains in Colorado, Wyoming, and Utah during the Laramide orogeny in Late Cretaceous and Early Tertiary time.

  10. Glacial Retreat and Associated Glacial Lake Hazards in the High Tien Shan

    A number of studies have identified glacial retreat throughout the greater Himalayan region over the past few decades, but the Karakorum region remains an anomaly with large stagnating or advancing glaciers. The glacial behavior in the Tien Shan is still unclear, as few studies have investigated mass balances in the region. This study focuses on the highest peaks of the Tien Shan mountain range, in the region of Jengish Chokusu along the Kyrgyzstan-China-Kazakhstan border. In a first step, a 30-year time series of Landsat imagery (n=27) and ASTER imagery (n=10) was developed to track glacial growth and retreat in the region. Using a combination of spectral and topographic information, glacial outlines are automatically delineated. As several important glaciers in the study region contain medium to high levels of debris cover, our algorithm also improves upon current methods of detecting debris-covered glaciers by using topography, distance weighting methods, river networks, and additional spectral data. Linked to glacial retreat are glacial lake outburst floods (GLOFs) that have become increasingly common in High Mountain Asia over the last few decades. As glaciers retreat, their melt water is often trapped by weakly bonded moraines. These moraines have been known to fail due to overtopping caused by surge waves created by avalanches, rockslides, or glacial calving. A suite of studies throughout High Mountain Asia have used remotely-sensed data to monitor the formation and growth of glacial lakes. In a second step of the work, lake-area changes over the past 15 years were tracked monthly and seasonally using dense Landsat/ASTER coverage (n=30) with an automatic procedure based on spectral and topographic information. Previous work has identified GLOFs as a significant process for infrastructural damage in the southern Tien Shan/northern Pamir, as well as in the better studied Himalaya region. Lake identification and quantification of lake-growth rates is a valuable

  13. Les transformations du jeûne chez les chrétiens d'Orient

    Directory of Open Access Journals (Sweden)

    2006-11-01

    Full Text Available Dans le christianisme, les règles du jeûne et de l’abstinence sont extrêmement complexes, dans leur rythme annuel et dans leurs prescriptions alimentaires, ce qui les distingue nettement de la pratique musulmane. C’est peut-être davantage dans l’anthropologie sous-jacente qu’on pourrait déterminer des conceptions communes aux deux religions. Ces règles se sont élaborées progressivement, entre le ive et le xiiie siècle, différenciant les Églises orientales de l’Église romaine, mais introduisant aussi des distinctions entre Églises orientales rivales. Il est assez difficile de se former une opinion claire sur les prescriptions et sur leur application concrète dans chaque groupe de chrétiens.À partir du xviie siècle, les Églises orientales se voient interrogées à propos de leurs pratiques en matière de jeûne et d’abstinence par les missionnaires et les érudits latins, et sommées de définir des règles strictes et définitives. En même temps, l’introduction des références du catholicisme latin fait perdre le sens du jeûne comme oeuvre collective, au profit d’une ascèse personnelle et intériorisée, centrée sur la pratique des sacrements. Les transformations du jeûne deviennent alors symptôme de la « modernisation » en cours chez les chrétiens orientaux.

    Polarimetry constitutes one of the fundamental tools for characterizing the surface texture and composition of airless Solar System bodies. In 2006, polarimetric observations led to the discovery of a new type of asteroids, which displays a peculiar polarimetric response. These asteroids are collectively known as "Barbarians", from (234) Barbara the first discovered one.The most commonly accepted explanation for this perculiar polarization response seems to be the presence of a high percentage of fluffy-type Calcium Aluminium-rich Inclusions (CAIs), whose optical properties could produce the observed polarization. Their reflectance spectra also exibit an absorption feature in the near-infrared around 2.1-2.2 microns, that is characteristic of this peculiar group.Based on these results, we organized a systematic polarimetric and near-infrared observational campaign of known Barbarians or candidate asteroids. These campaigns include members of the family of 1040 Klumpkea, 2085 Henan and 729 Watsonia, which are known to contain Barbarian and/or L-type asteroids also suspected to have such a polarimetric behaviour. We have made use of the ToPo polarimeter at the 1m telescope of the Centre pédagogique Planète et Univers (C2PU, Observatoire de la Côte d'Azur, France). The spectroscopic observations in the near-infrared were obtained with the SpeX instrument at the NASA's InfraRed Telescope Facility (IRTF).By combining polarimetry and spectroscopy we find a correlation between the abundance of CAIs and the inversion angle of the phase-polarization curve of Barbarian asteroids. This is the first time that a direct link has been established between a specific polarimetric response and the surface composition of asteroids. In addition, we find a considerable variety of CAI abundance from one object to the other, consistent with a wide range of possible albedos. Since these asteroids constitute a reservoir of primitive Solar System material, understanding their origin can

    We measured changes in the main physical and chemical properties, flavour compounds and microbial diversity in suan-cai during natural fermentation. The results showed that the pH and concentration of soluble protein initially decreased but were then maintained at a stable level; the concentration of nitrite increased in the initial fermentation stage and after reaching a peak it decreased significantly to a low level by the end of fermentation. Suan-cai was rich in 17 free amino acids. All of the free amino acids increased in concentration to different degrees, except histidine. Total free amino acids reached their highest levels in the mid-fermentation stage. The 17 volatile flavour components identified at the start of fermentation increased to 57 by the mid-fermentation stage; esters and aldehydes were in the greatest diversity and abundance, contributing most to the aroma of suan-cai. Bacteria were more abundant and diverse than fungi in suan-cai; 14 bacterial species were identified from the genera Leuconostoc, Bacillus, Pseudomonas and Lactobacillus. The predominant fungal species identified were Debaryomyces hansenii, Candida tropicalis and Penicillium expansum.

    Candida albicans is a commensal fungal pathogen that is often found as part of the human microbial flora. The aim of the present study was to establish a relationship between diverse genotypes and phenotypes of clinical isolates of C. albicans. Totally 231 clinical isolates were collected and used for genotyping and phenotypic switching analysis. Based on the microsatellite locus (CAI) genotyping assay, 65 different genotypes were identified, and some dominant types were found in certain human niches. For example, the genotypes of 30-44 and 30-45 were enriched in vaginal infection samples. C. albicans has a number of morphological forms including the single-celled yeasts, multicellular filaments, white, and opaque cell types. The relationship between the CAI genotype and the ability to undergo phenotypic switching was examined in the clinical isolates. We found that the strains with longer CAA/G repeats in both alleles of the CAI locus were more opaque competent. We also discovered that some MTL heterozygous (a/alpha) isolates could undergo white-opaque switching when grown on regular culture medium (containing glucose as the sole carbon source). Our study establishes a link between phenotypic switching and genotypes of the CAI microsatellite locus in clinical isolates of C. albicans.

    The NEC 250 kV single stage AMS accelerator (SSAMS) was installed two years ago at the Center for Applied Isotope Studies (CAIS), University of Georgia. The accelerator is primarily being used for radiocarbon measurements to test the authenticity of natural and bio-based samples while all other samples such as geological, atmospheric, marine and archaeological. are run on the 500 kV, NEC 1.5SDH-1 model tandem accelerator, which has been operating since 2001. The data obtained over a six months period for OXI, OXII, ANU sucrose and FIRI-D are discussed. The mean value of ANU sucrose observed to be slightly lower than the consensus value. The processed blanks on SSAMS produce lower apparent age compared to the tandem accelerator as expected.

  20. Dietary Changes over Time in a Caiçara Community from the Brazilian Atlantic Forest

    2006-12-01

    Full Text Available Because they are occurring at an accelerated pace, changes in the livelihoods of local coastal communities, including nutritional aspects, have been a subject of interest in human ecology. The aim of this study is to explore the dietary changes, particularly in the consumption of animal protein, that have taken place in Puruba Beach, a rural community of caiçaras on the São Paulo Coast, Brazil, over the 10-yr period from 1992-1993 to 2002-2003. Data were collected during six months in 1992-1993 and during the same months in 2002-2003 using the 24-hr recall method. We found an increasing dependence on external products in the most recent period, along with a reduction in fish consumption and in the number of fish species eaten. These changes, possibly associated with other nonmeasured factors such as overfishing and unplanned tourism, may cause food delocalization and a reduction in the use of natural resources. Although the consequences for conservation efforts in the Atlantic Forest and the survival of the caiçaras must still be evaluated, these local inhabitants may be finding a way to reconcile both the old and the new dietary patterns by keeping their houses in the community while looking for sources of income other than natural resources. The prospect shown here may reveal facets that can influence the maintenance of this and other communities undergoing similar processes by, for example, shedding some light on the ecological and economical processes that may occur within their environment and in turn affect the conservation of the resources upon which the local inhabitants depend.

    Glacier lake outburst floods (GLOFs) and related debris flows are among the most significant natural threats in the Tien Shan Mountains of Kyrgyzstan and have even caused the loss of life and damage to infrastructure in its capital Bishkek. An improved understanding of the occurrence of this process is essential so as to be able to design reliable disaster risk reduction strategies, even more so in view of ongoing climate change and scenarios of future evolutions. Here, we apply a dendrogeomorphic approach to reconstruct past debris-flow activity on the Aksay cone (Ala-Archa valley, Kyrgyz range), where outbursting glacier lakes and intense rainfalls have triggered huge debris flows over the past decades. A total of 96 Picea abies (L.) Karst. trees growing on the cone and along the main channel have been selected based on the evidence of past debris-flow damage in their trunks; these trees were then sampled using increment borers. The dating of past events was based on the assessment of growth disturbances (GD) in the tree-ring records and included the detection of injuries, tangential rows of traumatic resin ducts, reaction wood, and abrupt growth changes. In total, 320 GD were identified in the tree-ring samples. In combination with aerial imagery and geomorphic recognition in the field, reactions in trees and their position on the cone have allowed reconstruction of the main spatial patterns of past events on the Aksay cone. Our findings suggest that at least 27 debris flows have occurred on the site between 1877 and 2015 and point to the occurrence of at least 17 events that were not documented prior to this study. We also observe high process activity during the 1950s and 1960s, with major events on the cone in 1950, 1966, and 1968, coinciding with phases of slight glacier advance. The spatial analyses of events also point to two different spatial patterns, suggesting that quite dissimilar magnitudes probably occurred during glacier lake outburst floods and

    A search for short-lived {sup 10}Be in 21 calcium-aluminum-rich inclusions (CAIs) from Isheyevo, a rare CB/CH chondrite, showed that only 5 CAIs had {sup 10}B/{sup 11}B ratios higher than chondritic correlating with the elemental ratio {sup 9}Be/{sup 11}B, suggestive of in situ decay of this key short-lived radionuclide. The initial ({sup 10}Be/{sup 9}Be){sub 0} ratios vary between {approx}10{sup -3} and {approx}10{sup -2} for CAI 411. The initial ratio of CAI 411 is one order of magnitude higher than the highest ratio found in CV3 CAIs, suggesting that the more likely origin of CAI 411 {sup 10}Be is early solar system irradiation. The low ({sup 26}Al/{sup 27}Al){sub 0} [{<=} 8.9 Multiplication-Sign 10{sup -7}] with which CAI 411 formed indicates that it was exposed to gradual flares with a proton fluence of a few 10{sup 19} protons cm{sup -2}, during the earliest phases of the solar system, possibly the infrared class 0. The irradiation conditions for other CAIs are less well constrained, with calculated fluences ranging between a few 10{sup 19} and 10{sup 20} protons cm{sup -2}. The variable and extreme value of the initial {sup 10}Be/{sup 9}Be ratios in carbonaceous chondrite CAIs is the reflection of the variable and extreme magnetic activity in young stars observed in the X-ray domain.

    Morphogenetic features of soils on the selected plots in the Cat Tien National Park in southern Vietnam have been studied with the use of a set of morphological, analytical, and instrumental methods. The lithological factor and topographic position play the leading role in the development of the particular genetic soil features. The soils can be subdivided into four groups according to these factors. The soils developing from volcanic deposits with a predominance of tephra can be classified as thin clayey brown tropical soils (Dystric Skeletic Rhodic Cambisols (Clayic)), and the soils developed from less weathered colluvial derivatives of basalts with some admixture of tephra can be classified as dark-humus clayey tropical soils (Skeletic Greyzemic Umbrisols (Clayic)). Very poor soils developed from the eluvium of argillites are classified as thin weakly developed clayey tropical soils (Dystric Regosols (Clayic)). The soils forming from the alluvial sediments of different textures are classified as alluvial loamy sandy soils (Dystric Fluvisols (Arenic, Drainic)) and as alluvial clay loamy soils (Eutric Fluvisols (Episiltic, Endoclayic)).

    The species composition and termite community populations were studied and the total land termites biomass was estimated in five forest habitats of Cat Tien National Park, Southern Vietnam. Twenty-four species of two families, Rhinotermitidae (1 species) and Termitidae (23 species), the predominant representatives of the subfamily Macrotermitinae, were found in mounds and in soil samples. On the test plots the density of termite mounds averaged 68 per hectare, primarily the mounds of three Macrotermes species. Destructive sampling allowed estimation of the caste composition and total community biomass based on six termite mounds of the prevailing species (Globitermes sulphureus, Microcerotermes burmanicus, Macrotermes carbonarius, M. gilvus, M. malaccensis, and Hypotermes obscuriceps). The total number of termites in the nests ranged from 65 000 to 3 150 000 individuals with the total biomass ranging from 185 to 2440 g live weight. The total abundance of nesting Macrotermes species alone could conservatively be estimated as 2.5 million individuals and 20.5 kg live weight per hectare. The number of soil- and litter-feeding termites averaged for the test plots was estimated at about 60 ind./m2. Four species dominating on the test plots (M. carbonarius, M. gilvus, M. malaccensis, and H. obscuriceps) belong to active tree litter feeders.

  5. Development of Petrov glacial-lake system (Tien Shan and outburst risk assessment

    Directory of Open Access Journals (Sweden)

    I. A. Torgoev

    2013-01-01

    Full Text Available Global climate warming causes an intensive melting and retreat of glaciers in the Tien Shan mountains. Melting water of glaciers causes overfilling of high mountain lakes. The increase of the surface and volume of the Petrov Lake accompanied with the decrease of stability of the dam represents an extremely dangerous situation that can produce a natural disaster. Failure can happen due to erosion, a buildup of water pressure, an earthquake or if a large enough portion of a glacier breaks off and massively displaces the waters in a glacial lake at its base. In case of the lake dam rupture, flooding of a disposal site of highly toxic tailing from the gold mine Kumtor is a threat. If this happens, the toxic waste containing cyanides would contaminate a large area in the Naryn (Syrdarya river basin. Even if the flooding of the disposal site does not occur, the damage after lake dam fracture will be immense due to the glacial lake outburst flood may be a devastating mudslide. In order to prevent or reduce the risk of this event we recommend performing engineering surveys for the development and implementation of the project for the controlled reduction of water level in the Blue Bay of the Petrov Lake to a safe volume.

  6. Climate change and glacier retreat in northern Tien Shan (Kazakhstan/Kyrgyzstan) using remote sensing data

    This paper presents an analysis of precipitation and temperature trends and a GIS-supported investigation of the related glacier change in the mountain ridges Zailiyskiy and Kungey Alatau, which represent an important part of the northern Tien Shan. The recent glacier coverage was delineated in a semi-automated way using a TM4/TM5 ratio image of a Landsat ETM Scene from the year 1999 and a merged ASTER/SRTM3-DEM. The extent of these glaciers is compared to that of the glaciers in the Soviet Glacier Inventory [UdSSR, Academica Nauk (1966 to 1983). Katalog Lednikov SSSR (in Russian), Gidrometeoizdat. Leningrad], which represents the situation in study area in approx. 1955. Regionalization of temperature and precipitation as well as solar radiation calculation was conducted in order to determine the climate situation at the glaciers. Trend and correlation analysis for the period from 1879 to 2000 at 16 climate stations showed a temperature increase, which have become pronounced since the 1950s. Another strong increase occurred at the beginning of the 1970s and since around 1980, the temperatures have generally stayed at this high level. The trend coefficient was about 0.8 K/100a for the period 1900 to 2000 and about 2.0 K/100a on average for the second half of the last century. The increase was about two times higher than the global average in northern Tien Shan from 1950 until 2000, where the increase was mainly due to temperature rise in autumn and winter. The increase is less pronounced in the mountainous areas, but still obvious. However, the higher temperature increase at the lower stations, located for the most part in cities or larger settlements, may be due in part to increased urbanization. For precipitation, there was a small increase on average, but no clear trend. On the average, the decrease in glacier extent was more than 32% between 1955 and 1999 in the investigated valleys of Zailiyskiy and Kungey Alatau. The glacier retreat was not homogeneous, but

    The Aktiuz-Boordu Mining District is located in the Northern Tien Shan in the eastern part of Kyrgyzstan. The region is characterized by nappe-folding structures and comprises strongly deformed Precambrian and Lower Paleozoic sedimentary, volcano-sedimentary, and metamorphic sequences. Metamorphic rocks are represented by crystalline schists, para- and orthogneisses, marble, migmatite, amphibolite and eclogite lenses. These rocks are thought to be the oldest in the Northern Tien Shan. The 2780-Ma Aktiuz complex has a total thickness of 2800-2900 m. Available U-Pb zircon age data for the Kemin Group migmatites yield ages of 2200 ± 50 Ma. Based upon their geological setting, multistage metamorphism and isotopic ages of retrograde metamorphism (1.1-1.9 Ga), these rocks reach a few kilometers in thickness and are subdivided into Archaean and Paleoproterozoic. The Archaean and Paleoproterozoic basement metamorphic rocks contain mineralization of various ages and types, including porphyry Cu, Au-sulphide, Au-Bi, barite, epithermal base metal and Au-Ag, REE and rare-metals. Two ore fields have been identified within the Aktiuz-Boordu Mining District, they are: (1) Taldybulak-Boordu, with Au, base metal, and porphyry Cu systems; (2) Aktiuz, with REE, rare- and base-metal deposits. Within the Paleozoic Taldybulak-Boordu volcanic structure, deposits and occurrences of Au are present at Taldybulak Levoberezhny, Chimbulak Zapadny, Karamoko and Kuranjailyau; of Pb at Boordu, Taldybulak Stary, Chimbulak Vostochny and Chimbulak Zapadny; of Mo at Karabulak, and of Cu at Berkut-Kashka. Almost all are found along the periphery of deeply eroded volcanoes. Rock types in the Taldybulak-Boordu ore field mainly comprise chlorite-amphibole and amphibole schists, amphibolites, and migmatites of the Paleoproterozoic Kuperlisay suite. The younger Paleoproterozoic Kokbulak and Kapchigay suites are represented by mica schists and granite gneisses, which are separated from the Kuperlisay suite

    In this paper we present a description of the new complex installation for the study of extensive air showers which was created at the Tien Shan mountain cosmic ray station, as well as the results of the test measurements made there in 2014-2016. At present, the system for registration of electromagnetic shower component consists of ∼100 detector points built on the basis of plastic scintillator plates with the sensitive area of 0.25 m2 and 1 m2, spread equidistantly over ∼104m2 space. The dynamic range of scintillation amplitude measurements is currently about (3 - 7) ·104, and there is a prospect of it being extended up to ∼106. The direction of shower arrival is defined by signal delays from a number of the scintillators placed cross-wise at the periphery of the detector system. For the investigation of nuclear active shower components a multi-tier 55 m2 ionization-neutron calorimeter with a sum absorber thickness of ∼1000 g/cm2, typical spatial resolution of the order of 10 cm, and dynamic range of ionization measurement channel about ∼105 was created. Also, the use of saturation-free neutron detectors is anticipated for registration of the high- and low-energy hadron components in the region of shower core. A complex of underground detectors is designed for the study of muonic and penetrative nuclear-active components of the shower. The full stack of data acquisition, detector calibration, and shower parameters restoration procedures are now completed, and the newly obtained shower size spectrum and lateral distribution of shower particles occur in agreement with conventional data. Future studies in the field of 1014 -1017 eV cosmic ray physics to be held at the new shower installation are discussed.

    In the late 19th and early 20th centuries, the northern Tien Shan of Kyrgyzstan and Kazakhstan was affected by a series of major M 6.9 to ~8 earthquakes. Ruptures affected either range fronts or range interiors. During these events (AD1885 Belovodskoe; AD1887 Verny; AD1889 Chilik; AD1911 Chon-Kemin; and AD1938 Kemino-Chu), neighboring faults ruptured and caused severe damage in the area of the Kyrgyz capital Bishkek and the former Kazakh capital Almaty (previously also called Alma-Ata or Verny), which were located in the epicentral areas. As recurrence intervals along single faults in this region are on the order of hundreds to thousands of years, such a sequence of earthquakes is not known in the remaining historic record. Earlier events may thus be recorded in long-term geomorphic archives. Through a combination of high-resolution offset measurements in the field, cosmogenic nuclide and luminescence dating of Quaternary landforms, stratigraphic analysis, and paleoseismological trenching, we evaluate the Quaternary deformation and analyze the paleoseismic history of neighboring fault systems along the Kyrgyz range mountain front. Our study sites are located close to the Kyrgyz capital Bishkek and include the epicentral area of the M6.9 Belovodskoe event of AD1885, but also the region west of it, which was not affected by this remarkable earthquake sequence. To date, the paleoseismic and historical seismic records for the Kyrgyz range indicate segmented ruptures that hardly exceed magnitude seven. Based on scaling relationships, however, the linked fault systems would be capable of generating M 8-events, similar to the long segmented ruptures observed in the mountain interior farther east during the late nineteenth and early twentieth centuries. The available observations, thus, point to incomplete fault ruptures along the mountain front, rather than earthquakes failing along a full rupture length.

    Cai Yuanpei wrote a great many biographical writings in his life though he wasn' t famous for writing biography. In the period of his formative education and studying freely, he accumulated the attainment of biographical writing and cultivated gradually the sense of cultural identification based on Chinese ancient bi- ography. When embarking on political revolution and educational innovation, he became more active in bio- graphical writing, especially choosing those revolutionaries, relatives and friends as leading characters. In his later years, he wrote autobiography with a style of annals suggested by Hu Shi. All in all, it was very obvious that Cai should be a helpful promotion to modem transformation of Chinese biographical idea though he wasn' t determined biographical writer and researcher, including his lack of more profound biographical theories and very self-conscious sense of modem biographical style.%蔡元培并不是一位以写作传记而闻名的文学家,但在一生中写下了大量的传记作品。在接受启蒙教育和“自由”读书的过程中,他积累了良好的传记写作素养,逐渐形成了对中国传记文化的认同感。随着政治革命、教育革新等活动的展开,他更是积极写作各种人物传记,其中的革命家传和亲友传最具特色。晚年在胡适的影响下用年谱体写作自传。尽管蔡元培的志向并不在传记写作及研究上,此外亦无十分深刻的传记理论见解和非常自觉的现代传记文体意识,但对中国传记文学观念的现代转型具有一定的助推作用。

    宋代书法"尚意"的思潮,是一代文宗欧阳修、蔡襄和苏轼等人引领下形成的。蔡襄的书法和理论作为中国传统书法文化艺术的组成部分,具有承前启后的作用。然而在很长的历史时期里,学界在研究蔡襄的诗和书法时有"论者或不然",或认为"宋四大家"的书法是蔡京而非蔡襄等悖论。现根据史料,让我们以今人的眼光对蔡襄的书法进行整体的审视和评价。%The calligraphy in Song dynasty had the trend of "Shang Yi" under the guidance of Ouyang Xiu, Cai Xiang and Su Shi. Cai Xiang's calligraphy and theory, as one part of the traditional Chinese culture, have played an important role in linking the past and the future in Chinese calligraphy. However, there were opposite voices in the academic circles during a long time, and furthermore, Cai Jing, instead of Cai Xiang, is one of "four great calligraphers in Song dynasty", which is a fallacy in today's perspective. Now with the help of historical records, this paper gives overall review and evaluation on his works.

    Glacioclimatological research in the central Tien Shan was performed in the summers of 1998 and 1999 on the South Inilchek Glacier at 5100-5460 m. A 14.36 m firn-ice core and snow samples were collected and used for stratigraphic, isotopic, and chemical analyses. The firn-ice core and snow records were related to snow pit measurements at an event scale and to meteorological data and synoptic indices of atmospheric circulation at annual and seasonal scales. Linear relationships between the seasonal air temperature and seasonal isotopic composition in accumulated precipitation were established. Changes in the ??18O air temperature relationship, in major ion concentration and in the ratios between chemical species, were used to identify different sources of moisture and investigate changes in atmospheric circulation patterns. Precipitation over the central Tien Shan is characterized by the lowest ionic content among the Tien Shan glaciers and indicates its mainly marine origin. In seasons of minimum precipitation, autumn and winter, water vapor was derived from the and and semiarid regions in central Eurasia and contributed annual maximal solute content to snow accumulation in Tien Shan. The lowest content of major ions was observed in spring and summer layers, which represent maximum seasonal accumulation when moisture originates over the Atlantic Ocean and Mediterranean and Black Seas.

    The Controlled Auto-Ignition (CAI) combustion, also known as Homogeneous Charge Compression Ignition (HCCI), was achieved by trapping residuals with early exhaust valve closure in conjunction with direct injection. Multi-cycle 3D engine simulations have been carried out for parametric study on four different injection timings in order to better understand the effects of injection timings on in-cylinder mixing and CAI combustion. The full engine cycle simulation including complete gas exchange and combustion processes was carried out over several cycles in order to obtain the stable cycle for analysis. The combustion models used in the present study are the Shell auto-ignition model and the characteristic-time combustion model, which were modified to take the high level of EGR into consideration. A liquid sheet breakup spray model was used for the droplet breakup processes. The analyses show that the injection timing plays an important role in affecting the in-cylinder air/fuel mixing and mixture temperature, which in turn affects the CAI combustion and engine performance.

    I-Xe analyses were carried out for chondrules and refractory inclusions from the two CV3 carbonaceous chondrites Mokoia and Vigarano (representing the oxidized and reduced subgroups, respectively). Although some degree of disturbance to the I-Xe system is evident in all of the samples, evidence is preserved of aqueous alteration of CAIs in Mokoia 1 Myr later than the I-Xe age of the Shallowater standard and of the alteration of a chondrule (V3) from Vigarano ~0.7 Myr later than Shallowater. Other chondrules in Mokoia and Vigarano experienced disturbance of the I-Xe system millions of years later and, in the case of one Vigarano chondrule (VS1), complete resetting of the I-Xe system after decay of essentially all 129I, corresponding to an age more than 80 Myr after Shallowater. Our interpretation is that accretion and processing to form the Mokoia and Vigarano parent bodies must have continued for at least 4 Myr and 80 Myr, respectively. The late age of a chondrule that shows no evidence for any aqueous alteration or significant thermal processing after its formation leads us to postulate the existence of an energetic chondrule-forming mechanism at a time when nebular processes are not expected to be important.

  17. Autonomous geodynamics of the Pamir-Tien Shan junction zone from seismology data

    The geodynamics of the Tajik Depression, the junction zone of the Pamirs and Tien Shan, is typically considered in the context of plate tectonic concept, which implies intense subhorizontal compression of the zone resulting from the subduction of the Indian and Eurasian lithospheric plates. This convergence has been reliably confirmed by the GPS measurements. However, the joint analysis of the geological structure, seismicity, and geodimeter measurements conducted during a few years at the Garm geodynamical testing site of the Schmidt Institute of Physics of the Earth, Russian Academy of Sciences, demonstrates a widening of the Tajik Depression instead of its shortening, as should be expected from the subhorizontal compression predominant in the present-day stress-state of this region. This conclusion, together with the data from the other regions, suggests that, along with the plate tectonic mechanisms, there are also other, local, autonomous drivers that contribute to the tectogenesis of this region. Besides, the probable existence of these autonomous sources within the Tajik Depression directly follows from the seismology data. Among them is the crustal spreading within the depression suggested by the seismotectonic displacements in the focal mechanisms of the earthquakes. These displacements are directed in different azimuths off the axial's most subsided part of the depression at a depth of 20-30 km. Above this region the distribution of seismotectonic deformations (STD) is chaotic. This pattern of deformation is barely accounted for by a simple model of subhorizontal compression of the Earth's crust in the region. In our opinion, these features of the seismotectonic deformation in the crust within the studied part of the Tajik Depression is probably associated with the gain in the volume of the rocks due to the inflow of the additional material, which is supplied from the bottom crust or upper mantle by the deep fluids. This increase in the rock volume

    Intramural gradients of intracellular Ca(2+) (Ca(i)(2+)) Ca(i)(2+) handling, Ca(i)(2+) oscillations, and Ca(i)(2+) transient (CaT) alternans may be important in long-duration ventricular fibrillation (LDVF). However, previous studies of Ca(i)(2+) handling have been limited to recordings from the heart surface during short-duration ventricular fibrillation. To examine whether abnormalities of intramural Ca(i)(2+) handling contribute to LDVF, we measured membrane voltage (V(m)) and Ca(i)(2+) during pacing and LDVF in six perfused canine hearts using five eight-fiber optrodes. Measurements were grouped into epicardial, midwall, and endocardial layers. We found that during pacing at 350-ms cycle length, CaT duration was slightly longer (by ≃10%) in endocardial layers than in epicardial layers, whereas action potential duration (APD) exhibited no difference. Rapid pacing at 150-ms cycle length caused alternans in both APD (APD-ALT) and CaT amplitude (CaA-ALT) without significant transmural differences. For 93% of optrode recordings, CaA-ALT was transmurally concordant, whereas APD-ALT was either concordant (36%) or discordant (54%), suggesting that APD-ALT was not caused by CaA-ALT. During LDVF, V(m) and Ca(i)(2+) progressively desynchronized when not every action potential was followed by a CaT. Such desynchronization developed faster in the epicardium than in the other layers. In addition, CaT duration strongly increased (by ∼240% at 5 min of LDVF), whereas APD shortened (by ∼17%). CaT rises always followed V(m) upstrokes during pacing and LDVF. In conclusion, the fact that V(m) upstrokes always preceded CaTs indicates that spontaneous Ca(i)(2+) oscillations in the working myocardium were not likely the reason for LDVF maintenance. Strong V(m)-Ca(i)(2+) desynchronization and the occurrence of long CaTs during LDVF indicate severely impaired Ca(i)(2+) handling and may potentially contribute to LDVF maintenance.

    The 1911 Ms 8.2 Kebin (Chon-Kemin) earthquake in the Northern Tien Shan, Kyrgyzstan is one of the largest historic intraplate reverse-faulting events. Documentation of slip distribution and fault geometry for major historic earthquakes, such as the Chon-Kemin event, provide important data on their source physics and seismotectonics. These data also provide insight into mechanical interaction with other large regional earthquakes, notably the 1887 Ms 7.3 Verny and 1889 Ms 8.3 Chilik events. Through detailed aerial photo mapping, examination of historic data (Bogdonovich et al., 1914), and two seasons of fieldwork, we mapped the entire 200 km of the1911 rupture and associated off-fault deformation and mass movements at > 1:50,000. At the 1911 events western end, the south dipping Djel Aryk section closely follows the range front at the southern edge of the Djel Aryk Valley. Mapping by Bogdonovich et al. indicates 1.5 km of rupture west of the Chu River in 1911 but 10-20 m high fault scarps further west in the Djel Aryk Valley indicate late Pleistocene paleoseismic activity. The Lower Chon-Kemin section stretches from the Chon-Kemin gorge to Chundi-Su. The fault dips steeply south and offset landforms indicate a left-lateral slip component. Vertical 1911 displacements are 1-3 m. Most of this portion of the 1911 rupture is located 500-1500 m above the Chon-Kemin Valley on the northern flank of the Kungei-Alatau Range. Bogdonovich et al. do not report 1911 rupture between Dyure River and Chundi-Su despite clear 10-30 m tall scarps offsetting Holocene landforms. The lack of mapped ground rupture in this area in 1911 suggests either a failure of the Bogdonovich team to reach this section of fault or that the earthquake failed to rupture here, despite clearly having done so prehistorically. The Upper Chon-Kemin section comprises steeply dipping to vertical discontinuous fractures located on steep slopes above the valley floor. Bogdonovich et al. report discontinuous

    Nitrogen and noble gas (Ne-Ar) abundances and isotope ratios, determined by CO2 laser extraction static mass spectrometry analysis, as well as Al-Mg and O isotope data from secondary ion mass spectrometry (SIMS) analyses, are reported for a type B calcium-aluminum-rich inclusion (CAI) from the CV3 chondrite NWA 8616. The high (26Al/27Al)i ratio of (5.06 ± 0.50) × 10-5 dates the last melting event of the CAI at 39-99+109ka after "time zero", limiting the period during which high-temperature exchanges between the CAI and the nebular gas could have occurred to a very short time interval. Partial isotopic exchange with a 16O-poor reservoir resulted in Δ17O > -5‰ for melilite and anorthite, whereas spinel and Al-Ti-pyroxene retain the inferred original 16O-rich signature of the solar nebula (Δ17O ⩽ -20‰). The low 20Ne/22Ne (⩽0.83) and 36Ar/38Ar (⩽0.75) ratios of the CAI rule out the presence of any trapped planetary or solar noble gases. Cosmogenic 21Ne and 38Ar abundances are consistent with a cosmic ray exposure (CRE) age of ∼14 to 20 Ma, assuming CR fluxes similar to modern ones, without any evidence for pre-irradiation of the CAI before incorporation into the meteorite parent body. Strikingly, the CAI contains 1.4-3.4 ppm N with a δ15N value of +8‰ to +30‰. Even after correcting the measured δ15N values for cosmogenic 15N produced in situ, the CAI is highly enriched in 15N compared to the protosolar nebula (δ15NPSN = -383 ± 8‰; Marty et al., 2011), implying that the CAI-forming region was contaminated by 15N-rich material within the first 0.15 Ma of Solar System history, or, alternatively, that the CAI was ejected into the outer Solar System where it interacted with a 15N-rich reservoir.

    Central Asia is a classic example for continental lithospheric folding. In particular, the Altay-Sayan belt in South-Siberia and the Kyrgyz Tien Shan display a special mode of lithospheric deformation, involving decoupled lithospheric mantle folding and upper crustal folding and faulting. A review of the paleostress data and tectono-stratigraphic evolution of the Kurai-Chuya basin in Siberian Altai, Zaisan basin in Kazakh South Altai and Issyk-Kul basin in Kyrgyz Tien Shan suggests that these basins were initiated in an extensional context and later inverted by a combination of fault-controlled deformation and flexural folding. They deformed by a combination of lithospheric buckling inducing surface tilting, uplift and subsidence, together with upper crustal fault-controlled deformation. They are good examples of Folded Lithospheric Basins (FLB) which typically form in a buckling lithosphere. Their characteristic basin fill and symmetry, inner structure, folding wavelength and amplitude, thermal regime and time frame are examined in relation to basement structure, stress field, strain rate, timing of deformation, and compared to existing modelling results. Both regions of active lithospheric folding have a heterogeneous crust with a long history of accretion-collision, subsequently reactivated as a far-field effect of the Indian-Eurasian collision. Thanks to the youthfulness of the tectonic deformation in this region (peak deformation in late Pliocene - early Pleistocene), the surface expression of lithospheric deformation is well documented by the surface topography and superficial tectonic structures.

    Major, trace, and rare earth elements (REE) were determined by inductively coupled plasma-mass spectrometer (ICP-MS) for dust particles that were extracted from fresh surface snow samples collected weekly or biweekly between March 2006 and January 2008 at Urumqi Glacier No. 1 (UG1) in Eastern Tien Shan, Central Asia. The UG1 dust shows average Fe/Al ratios of 0.7, Ca/Al ratios of 0.35, La/Th ratios of 2.62, Th/U ratios of 3.31, an Eu anomaly of 0.63, and L/HREE ratios of 7.87. Seasonal variation is significant in dust concentration, but is not observed in dust composition, which remains rather uniform throughout the sampling period. The compositional homogeneity suggests that dust materials in UG1 are well mixed from their possible source areas. Fine materials from the Junggar Basin, and to a less extend from Tarim Basin, more closely resemble UG1 dust properties in their REE composition than do the local moraines, indicating that the dust in UG1 snow mainly comes from mid- to long-range source areas. The HYSPLIT model results suggest that the Westerlies, Arctic air masses and local winds are the main circulations for dust transport to Eastern Tien Shan.

  7. Calcium-aluminum-rich inclusions with fractionation and unidentified nuclear effects (FUN CAIs): II. Heterogeneities of magnesium isotopes and 26Al in the early Solar System inferred from in situ high-precision magnesium-isotope measurements

    Calcium-aluminum-rich inclusions with isotopic mass fractionation effects and unidentified nuclear isotopic anomalies (FUN CAIs) have been studied for more than 40 years, but their origins remain enigmatic. Here we report in situ high precision measurements of aluminum-magnesium isotope systematics of FUN CAIs by secondary ion mass spectrometry (SIMS). Individual minerals were analyzed in six FUN CAIs from the oxidized CV3 carbonaceous chondrites Axtell (compact Type A CAI Axtell 2271) and Allende (Type B CAIs C1 and EK1-4-1, and forsterite-bearing Type B CAIs BG82DH8, CG-14, and TE). Most of these CAIs show evidence for excess 26Mg due to the decay of 26Al. The inferred initial 26Al/27Al ratios [(26Al/27Al)0] and the initial magnesium isotopic compositions (δ26Mg0) calculated using an exponential law with an exponent β of 0.5128 are (3.1 ± 1.6) × 10-6 and 0.60 ± 0.10‰ (Axtell 2271), (3.7 ± 1.5) × 10-6 and -0.20 ± 0.05‰ (BG82DH8), (2.2 ± 1.1) × 10-6 and -0.18 ± 0.05‰ (C1), (2.3 ± 2.4) × 10-5 and -2.23 ± 0.37‰ (EK1-4-1), (1.5 ± 1.1) × 10-5 and -0.42 ± 0.08‰ (CG-14), and (5.3 ± 0.9) × 10-5 and -0.05 ± 0.08‰ (TE) with 2σ uncertainties. We infer that FUN CAIs recorded heterogeneities of magnesium isotopes and 26Al in the CAI-forming region(s). Comparison of 26Al-26Mg systematics, stable isotope (oxygen, magnesium, calcium, and titanium) and trace element studies of FUN and non-FUN igneous CAIs indicates that there is a continuum among these CAI types. Based on these observations and evaporation experiments on CAI-like melts, we propose a generic scenario for the origin of igneous (FUN and non-FUN) CAIs: (i) condensation of isotopically normal solids in an 16O-rich gas of approximately solar composition; (ii) formation of CAI precursors by aggregation of these solids together with variable abundances of isotopically anomalous grains-possible carriers of unidentified nuclear (UN) effects; and (iii) melt evaporation of these precursors

    Among the outstanding tectonic questions regarding the convergence between the Tien Shan and Tarim basin in northwestern China are the manner in which deformation is accommodated within their lithospheres, and the extent that the Tarim lithosphere underthrusts the Tien Shan. In particular, the amount and type of deformation within the Tarim basin is poorly understood. It is also uncertain if the convergence between the Tarim and the Tien Shan takes place mainly along a discrete boundary, or if the Tarim lithosphere simply indents into the Kazach shield, forming the Tien Shan through crustal thickening accommodated by a distributed series of thrust faults. In this study we use hypocenters from published earthquake catalogs and waveforms recorded by regional seismic networks to determine earthquake source parameters through regional centroid moment tensor inversion. The entire dataset consists of 160 earthquakes that occurred between 1969 and 2009 and with moment magnitudes between 3.5 and 7 distributed throughout the central Tien Shan and northwestern Tarim Basin. The estimated focal depths of these earthquakes range from the near-surface to about 44 km. Focal mechanisms throughout much of the Tien Shan indicate active deformation accommodated by thrust faults from at least the upper crust to 30 km depth. South of the Tien Shan, the Jia-shi earthquake sequence within the Tarim basin suggests that both crustal shortening and localized flexure are part of a complicated process involving rotational convergence. Inside the Tarim basin, two earthquakes with thrust faulting mechanisms near the crust-mantle boundary beneath the Bachu uplift imply a brittle rheology of the lower crust. High-angle thrust events occur broadly across the Tien Shan, suggesting that the Tarim lithosphere as a whole is strong and indents into the Kazach shield to create the mountain range.

    Fluffy Type A Ca-Al-rich inclusions (CAIs) containing reversely zoned melilite crystals are suggested to be aggregates of direct condensates from solar nebular gas. We conducted an investigation of 26Al-26Mg systematics of a fluffy Type A CAI from Vigarano, named V2-01, with known oxygen isotopic distributions of reversely zoned melilite crystals; we also conducted oxygen isotope measurements of coexisting minerals. Two of six reversely zoned melilite crystals show continuous variations in magnesium isotopic composition, with δ25Mg decreasing along the inferred direction of crystal growth, which supports the idea that they originated through condensation. Petrography suggests that the constituent minerals of V2-01 formed in the following order: first spinel and fassaite enclosed by melilite, then reversely zoned melilite crystals, and spinel and diopside in the Wark-Lovering rim. The spinel enclosed by melilite has 16O-rich compositions (Δ17O ∼ -24‰) and on an Al-Mg evolutionary diagram plots along model isochron with an initial value of (26Al/27Al)0 = (5.6 ± 0.2) × 10-5. The fassaite enclosed by melilite crystals shows variable oxygen isotopic compositions (Δ17O ∼ -12‰ and -17‰) and plots on an isochron with (26Al/27Al)0 = (5.6 ± 0.2) × 10-5. The oxygen isotopic compositions of reversely zoned melilite showed continuous variations in Δ17O along the inferred direction of crystal growth, suggesting that surrounding nebular gas, during the formation of the reversely zoned melilite, changed from 16O-poor (Δ17O values larger than -10‰) to 16O-rich (Δ17O ∼ -25‰). The six reversely zoned melilite crystals show indistinguishable initial 26Al/27Al values with an average (26Al/27Al)0 of (4.7 ± 0.3) × 10-5, which is clearly distinguishable from the value of enclosed spinel and fassaite, indicating a younger formation age than the enclosed spinel and fassaite. The spinel and diopside from the Wark-Lovering rim show 16O-rich compositions (Δ17O

    The variability of human chromosomal Q-heterochromatin regions (Q-HR) was studied in 385 newcomers well adapted to the extreme environmental conditions of Pamir and Tien-Shan, as well as in 284 representatives of the native population of these regions. Newcomers were found to represent a highly homogeneous group as regards all the quantitative characteristics of Q-HR variability, but at the same time they differed significantly from both native residents and individuals of similar nationality (Russians) living permanently at low altitude. Differences between these three groups in the amount of Q-HRs in their genome are discussed as evidence in favour of the hypothesis of the possible selective value of chromosomal Q-heterochromatin material in human adaptation to extreme environmental high-altitude conditions.

    The northern Tien Shan of Kyrgyzstan and Kazakhstan has been affected by a series of major earthquakes in the late 19th and early 20th centuries. To assess the significance of such a pulse of strain release in a continental interior, it is important to analyze and quantify strain release over multiple time scales. We have undertaken paleoseismological investigations at two geomorphically distinct sites (Panfilovkoe and Rot Front) near the Kyrgyz capital Bishkek. Although located near the historic epicenters, both sites were not affected by these earthquakes. Trenching was accompanied by dating stratigraphy and offset surfaces using luminescence, radiocarbon, and 10Be terrestrial cosmogenic nuclide methods. At Rot Front, trenching of a small scarp did not reveal evidence for surface rupture during the last 5000 years. The scarp rather resembles an extensive debris-flow lobe. At Panfilovkoe, we estimate a Late Pleistocene minimum slip rate of 0.2 ± 0.1 mm/a, averaged over at least two, probably three earthquake cycles. Dip-slip reverse motion along segmented, moderately steep faults resulted in hanging wall collapse scarps during different events. The most recent earthquake occurred around 3.6 ± 1.3 kyr ago (1σ), with dip-slip offsets between 1.2 and 1.4 m. We calculate a probabilistic paleomagnitude to be between 6.7 and 7.2, which is in agreement with regional data from the Kyrgyz range. The morphotectonic signals in the northern Tien Shan are a prime example of deformation in a tectonically active intracontinental mountain belt and as such can help understand the longer-term coevolution of topography and seismogenic processes in similar structural settings worldwide.

    We used the arrival times of local earthquakes and quarry blasts recorded by the Kyrgyzstan Broadband Network (KNET) to obtain three-dimensional (3-D) P and S wave velocity models of the upper crust beneath an actively deforming mountain front and its associated foreland in the Kyrgyz Tien Shan. The continuous velocity models, described by cubic B spline interpolation of the squared slowness over a regular 3-D grid, were computed by simultaneous inversion of hypocenter and medium parameters. Exact ray tracing was done in the smooth 3-D medium by shooting rays from the sources to the stations by an analytical perturbation method based on the paraxial ray theory. The deduced large, sparse, linear system was solved using the damped, iterative, least squares algorithm LSQR. The stability and resolution of the result was qualitatively tested by two synthetic tests: the spike test and the checkerboard resolution test. We found that the models are well resolved up to a depth of ˜27 km for most parts of our image domain. The P and S wave velocity models are consistent with each other and provide evidence for marked heterogeneity in the upper crustal structure beneath the northern Tien Shan. At shallower depths (<7 km) the sediment-filled foreland is imaged as a relatively lower velocity feature compared to the mountains, which are cored by crystalline basement rocks. In contrast, at midcrustal depths the mountains are underlain by relatively lower velocity materials compared to the foreland. A distinct contrast in velocity structure is also observed between the eastern and western parts of the Kyrgyz Range at midcrustal depths, with the presence of relatively higher velocities toward the east. The seismicity is concentrated near the traces of major active faults and extends deeper beneath the foreland compared to the mountains. The regional compression in the Tien Shan is accommodated along a series of high-angle reverse faults distributed throughout the orogenic system

    Due to successive block accretions, the polarity of structures and tectonic evolution of the Central Asian Orogenic Belt (CAOB) are still a matter of debate. There are several conflicting models about the polarity of subduction during the Paleozoic, the number of microplates and oceanic basins and the timing of tectonic events in Kyrgyz and Chinese Tien Shan. In this study, we propose new structural maps and cross-sections of Middle and South Kyrgyz Tien Shan (MTS and STS respectively). These cross-sections highlight an overall dextral strike-slip shear zone in the MTS and a north verging structure related to south-dipping subduction in the STS. These structures are Carboniferous in age and sealed by Mesozoic and Cenozoic deposits. In detail, the STS exhibits two deformation phases. The first one is characterized by coeval top-to-the north thrusting and top-to-the-South normal shearing at the boundaries of large continental unit that underwent High-Pressure (Eclogite facies) metamorphism. We ascribe this phase to the exhumation of underthrusted passive margin units of the MTS. The second one corresponds to a top to the North nappe stacking that we link to the last collisional events between the MTS and the Tarim block. Later on, during the Late Carboniferous, a major deformation stage is characterized by the deformation of the MTS and its thrusting over the NTS. This deformation occurred on a large dextral shear zone between the NTS and the MTS known as Song-Kul Zone or Nikolaiev Line as a "side effect" of the Tarim/MTS collision. Based on these observations, we propose a new interpretation of the tectonic evolution of the CAOB. The resulting model comprises the underthrusting of the MTS-Kazakh platform beneath the Tarim and its exhumation followed by the folding, shortening and thickening of the internal metamorphic units during the last collisional events which partitioned the deformation between the STS and the MTS. Finally, the docking of the large Tarim Craton

  18. A New Type of Foreign Clast in A Polymict Ureilite: A CAI or AL-Rich Chondrule

    Introduction: Polymict ureilites are breccias interpreted to represent regolith formed on a ureilitic asteroid [1-3]. They consist of approximately 90-95% clasts of various ureilite types (olivine-pyroxene rocks with Fo 75-95), a few % indigenous feldspathic clasts, and a few % foreign clasts [4-20]. The foreign clasts are diverse, including fragments of H, L, LL and R chondrites, angrites, other achondrites, and dark clasts similar to CC [6,7,9-19]. We report a new type of foreign clast in polymict ureilite DaG 999. Methods: Clast 8 in Dar al Gani (DaG) 999/1 (Museum fur Naturkunde) was discovered during a survey of feldspathic clasts in polymict ureilites [19,20]. It was studied by BEI, EMPA, and X-ray mapping on the JEOL 8530F electron microprobe at ARES, JSC. Petrography and Mineral Compositions: Clast 8 is sub-rounded to irregular in shape, approximately 85 micrometers in diameter, and consists of approximately 68% pyroxene and 32% mesostasis (by area). Part of the pyroxene (top half of clast in Fig. 1a and 2) shows a coarse dendritic morphology; the rest appears massive. Mesostasis may be glassy and contains fine needles/grains of pyroxene. The pyroxene has very high CaO (23.5 wt.%) and Al2O3 (19.7 wt.%), with the formula: (Ca(0.91)Mg(0.63)Fe(0.01)Al(sup VI) (0.38)Cr(0.01)Ti(0.05)1.99 Si2O6. The bulk mesostasis also has very high Al2O3 (approximately 26 wt.%). A bulk composition for the clast was obtained by combining modal abundances with phase compositions (Table 1, Fig. 3). Discussion: The pyroxene in clast 8 has a Ca-Al-(Ti)- rich (fassaitic) composition that is clearly distinct from compositions of pyroxenes in main group ureilites [22] or indigenous feldspathic clasts in polymict ureilites [4-8]. It also has significantly higher Al than fassaite in angrites (up to approximately 12 wt.% [23]), which occur as xenoliths in polymict ureilites. Ca-Al-Ti rich pyroxenes are most commonly found in CAIs, Al-rich chondrules and other types of refractory

  19. Spatial-temporal structure of seismicity of the North Tien Shan and its changeunder effect of high energy electromagnetic pulses

    Full Text Available The effect of high-energy electromagnetic pulses emitted by a magnetohydrodynamic generator used as a source for deep electrical sounding of the crust on spatial-temporal structure of seismicity of the North Tien Shan is explored. Five-six years periodicity of changes in spatial distribution of seismicity was revealed. The effect of electromagnetic pulses increases the stability of the spatial distribution of seismicity over time and simultaneously speeds up cycles of its transformations, which develop on stabilization background. Increasing of seismic energy release after electromagnetic impacts is observed basically in most active zones. Periodic variation of efficiency of earthquakes triggering on the distance to the MHD-generator was detected. It was shown that electromagnetic pulses give rise to an appreciable increase in the rate of local earthquakes, occurring around 2-6 days after the pulses. Total earthquakes energy released after start-ups was by 2.03·1015 J greater than the energy released before them. At the same time, the total energy transmitted by the MHD-generator was 1.1·109 J, i.e. six orders of magnitude smaller. Consequently, the electromagnetic pulses initiated the release of the energy that had been stored in the crust due to activity of natural tectonic processes in the form of comparatively small earthquakes, which leads to an additional release of tectonic stresses.

    Stable water isotope (??18O, ??D) data from a high elevation (5100 masl) ice core recovered from the Tien Shan Mountains, Kyrgyzstan, display a seasonal cycle in deuterium excess (d = ??D - 8*??18O) related to changes in the regional hydrologic cycle during 1994-2000. While there is a strong correlation (r2 = 0.98) between ??18O and ??D in the ice core samples, the regression slope (6.9) and mean d value (23.0) are significantly different than the global meteoric water line values. The resulting time-series ice core d profile contains distinct winter maxima and summer minima, with a yearly d amplitude of ???15-20???. Local-scale processes that may affect d values preserved in the ice core are not consistent with the observed seasonal variability. Data from Central Asian monitoring sites in the Global Network of Isotopes in Precipitation (GNIP) have similar seasonal d changes. We suggest that regional-scale hydrological conditions, including seasonal changes in moisture source, transport, and recycling in the Caspian/Aral Sea region, are responsible for the observed spatial and temporal d variability.

    The Tien-Shan is one of the largest mountain belts in the world. Its deformation is dominated by intermontane basins bounded by active thrust and reverse faulting. The Tien-Shan mountain belt is characterized by a very high rate of seismicity along its margins as well as within the Tien-Shan interior. The study area of the here presented work, the western part of the Tien-Shan region, is currently seismically active with small and moderate sized earthquakes. However, at the end of 19th beginning of 20th century, this region was struck by a remarkable series of large magnitude (M>7) earthquakes, two of them reached magnitude 8. These large earthquakes occurred before the global digital seismic network was installed and therefore were recorded only by analog seismic instruments. The processing of the analog is complicated especially due to the digitization of the records - a very time-consuming and delicate part. Therefore a special set of techniques is developed and modern methods are adapted for the digitized instrumental data analysis. Here presented study evaluates the impact of large magnitude M>7.0 earthquakes, in the Tien-Shan region, on the overall regional tectonics. It also investigates the accuracy of previously estimated source parameters for those earthquakes, which were mainly based on macroseismic observations, and re-estimate them based on the instrumental data. Ten strongest and most interesting historical earthquakes in Tien-Shan region are analyzed with in presented work. With the developed techniques, the source parameters of these major earthquakes are determined and their impact on the regional tectonics was investigated. The large magnitudes of the earthquakes are confirmed by instrumental data. The focal mechanisms of these earthquakes were determined providing evidence for responsible faults or fault systems.

  9. How much water will glaciers in the Chon Kemin valley (Tien Shan mountains, Kyrgyzstan) provide in the future?

    Climate-driven changes in glacier-fed streamflow regimes have direct implications on freshwater supply, irrigation and hydropower potential. Reliable information on current and future glaciation and runoff is thus crucial for water allocation. In summer-dry regions like Central Asia, glaciers play an important role in streamflow regimes, as meltwater from glaciers is released when other sources such as snowmelt are depleted. This situation is well reflected by the Chon Kemin River, an important tributary to the Chu River providing Kyrgyzstan's capital Bishkek with freshwater. Today, glaciers cover around 8% of the Chon Kemin valley (118 of 1'438 km2) and 30% of the headwater catchment (49 of 165 km2), but these glaciers in the low-altitude northern periphery of the Tien Shan mountains are melting particularly fast. Glacier shrinkage has considerable impacts on the seasonal and overall availability of water: In a first instance, shrinking glaciers supply ample quantities of water in the form of increased glacial runoff, but reduced glacier volume will ultimately result in a decrease in both glacier-fed and total runoff, if no other sources can offset reduced glacier melt. Although crucial for efficient water planning, it is largely unknown if the Tien Shan rivers have already passed this tipping point ("peak water"), or, if not yet, when this will happen. In our study, we assess past and future runoff changes in the Chon Kemin River to elucidate the timing of "peak water" and to quantify water availability in coming summers, when precipitation is expected to be even more scarce than today. Meteorological and hydrological data suggest that total runoff has increased in the past decades, particularly during summer and fall, probably as a result of increasing glacial meltwater. Annual fluctuations in precipitation and runoff have shown an asynchronous behavior in a first phase (1936 until early 1960s), but have then changed to a synchronous pattern (early 1960s until

  10. Regional based modeling approach for rainfall-induced debris flows in the continental-climatic Northern Tien Shan (SE Kazakhstan)

    The high mountain systems of Central Asia (Hindukush, Pamir and Tien Shan) are dominated by continental-climatic conditions. Nevertheless, westerly maritime air circulation and convective rainfalls during the summer season result in high rainfall intensities. In combination with a high availability of unconsolidated material rainfall triggered debris flows are prominent and intensive geomorphologic processes in these mountain areas. The presented study aims to figure out a regional based modeling approach for rainfall-induced debris flow processes based on combination of a disposition model for debris flow starting zones with process-flow models. The investigation area has a size of about 700 square kilometers and is situated in the Northern Tien Shan mountains in SE Kazakhstan (investigation areas: valleys of Prochadnaja, Big Almatinka, Little Almatinka and Left Talgar). The area is characterized by mountain forest zone, alpine meadows and high-alpine glaciated areas with the highest peaks at 4500m. In a first step the disposition (point of process triggering) of actual debris flows was analyzed. Due to different triggering mechanisms, the processes were divided into channel-type and slope-type debris flows. Detailed mapping of actual debris flows initiation areas and a GIS-based geostatistical disposition analysis are used to identify the main geofactor-variables and geofactor combinations which enhance the triggering of rainfall-induced debris flows. It can be shown that both, longtime variable geofactors (such as local geomorphology and hydrology) plays a significant role for triggering debris flows, as well as mid- and short time variable geofactors. Especially actual permafrost distribution and degradation plus glacier retreat comes into the focus of interest. This is most notably for rainfall induced slope-type debris flows which primarily are triggered in the discontinuous and continuous permafrost areas eroding younger unconsolidated material from actual

    The 1889 Ms 8.3 Chilik earthquake in the Northern Tien Shan Mountains of Kyrgyzstan and Kazakhstan is one of the largest historic intraplate reverse-faulting events. Documentation of slip distribution and fault geometry for major historic earthquakes, such as the Chilik event, provide important data on their source physics, seismotectonics, and hazard. These data also provide insight into potential mechanical interaction with other large regional earthquakes, notably the 1887 Ms 7.3 Verny and 1911 Ms 8.2 Kebin (Chon Kemin) events. Despite the importance of the Chilik event, very little is known about the earthquake's epicenter and the presence of associated ground rupture. Isoseismal's from historic shaking intensity data gathered immediately following the event were used to estimate the event magnitude and suggest an epicentral location in the northern foothills of the Kungey Ala-too range, 80-100 kilometers east-southeast of Almaty. Researchers who have visited this area report no evidence of ground rupture, suggesting that the event either did not rupture the ground surface or that the isoseismal data do not provide a sufficiently focused estimate of epicentral location. We have reanalyzed the shaking intensity data to update the estimate of the epicentral location. During June 2007 field work and in review of aerial photography, we observed extensive east-west trending and morphologically youthful km-long and 1-5 m high fault scarps on the eastern crest of the Kungey Ala-Too Range along the Kygyz-Kazak border north of Tyup. Contemporary reports of the 1911 Kebin earthquake did not document these structures, despite the thorough investigation of rupture to the west and northwest. The scarp lengths and their offsets indicate that they did not form in the M6.6 1978 Djalanash Tyup earthquake. Although located to the south of the isoseismal epicenter for the Chilik earthquake, the scarps observed near the range crest must be considered as possible candidates for

    Using a high-resolution ( 18 samples/year) major soluble ion record (Na+, K+, Mg2+, Ca2+, Cl-, NO3-, and SO42-) covering the period 1908-1995 A.D. from the Inilchek Glacier, Tien Shan, Kyrgyzstan, we provide a detailed climate and environmental proxy record for the region. Chemical concentrations, empirical orthogonal function analyses, and noncrustal excess calculations are used to identify natural and potential anthropogenic depositional trends. Dominant dust proxy species (i.e., Ca2+) reveal highest concentrations during the 1950s-1970s, with declining decadal trends through the end of the record. These trends likely reflect decreases in central Asian dust storm activity post-1950, which has been associated with coupled atmospheric circulation variability and anthropogenic activities. Comparison between Ca2+ and ERA-Interim (1979-1995) climate reanalysis data indicates a strong relationship to spring (March-May) geopotential height patterns in northwest China and southern Siberia associated with the Siberian High. Noncrustal contribution (excess) estimates of NO3-, K+, SO42-, and Cl- concentrations suggest discernable anthropogenic inputs began between the 1950s and 1970s, increased into the middle/late 1980s, and declined in the 1990s. Excess trends coincide with Former Soviet Union consumption, production, and emission of fossil fuels and fertilizers, reflecting the rapid growth of agriculture and industry, as well as economic declines in the middle to late 1980s/early 1990s. Excess-Cl- trends reflect timings that coincide with the construction of the Pavlodar Chemical Plant and the military production of Cl2 in Kazakhstan. NOAA Hybrid Single-Particle Lagrangian Integrated Trajectory back trajectory frequency analysis suggests eastern Uzbekistan (e.g., Fergana Valley), Kyrgyzstan, and southern Kazakhstan as the primary pollutant sources to the study region.

    Like in many other parts of the world, the glaciers in northern Tien Shan are receding and the permafrost is thawing and concomitant glacial lakes are developing. Outbursts of these glacial lakes pose severe hazards for the society. Over the last decade, several outbursts in this seismically active region are documented. Multi-temporal space imageries are an ideal means to study and monitor glaciers and glacial lakes over larger areas. Morphometric analyses and modelling approaches allow the estimation of the potential danger of glacial lake outburst floods (GLOFs). In this paper, we present a comprehensive approach to identify glaciers and the potentially dangerous glacial lakes based on multi-temporal space imagery from 1972 (Corona KH-4B), 1973 (Landsat MSS), 1991 (Landsat TM), 1999 (Landsat ETM+), 2000/2001/ (ASTER) 2005, and 2008 (Landsat TM) as well as morphometric analysis and modelling. The identification and monitoring of glacial lakes were carried out automatically using image ratioing and the Normalized Difference Water Index (except for the panchromatic Corona images). The results were evaluated and, if necessary, manually edited. The probability of the growth of a glacial lake was estimated by analysing glacier changes, glacier motion, and slope analysis. A permafrost model based on morphometric parameters, solar radiation and regionalised temperature conditions aided us to asses the effect of probable permafrost thawing. A GIS-based model was applied in order to simulate the possible downstream impact of a lake outburst. The findings of our studies indicate a continuous glacier recession with an increasing number and area of glacial lakes. This possibly leads into a higher risk of a glacial lake outburst. Finally, the lakes are classified according to their outburst probability and their downstream impact.

    Calcium-aluminum-rich inclusions (CAIs) are the key to understanding physical and chemical conditions in the nascent solar nebula. These inclusions have the oldest radiometric ages of solar system materials and are composed of phases that are predicted to condense early from a gas of solar composition. Thus, their chemistry and textures record conditions and processes in the earliest stages of development of the solar nebula. Type B inclusions are typically larger and more coarse grained than other types with substantial evidence that many of them were at least partially molten. Type B inclusions are further subdivided into Type B1 (possess thick melilite mantle) and Type B2 (lack melilite mantle). Despite being extensively studied, the origin of the melilite mantles of Type B1 inclusions remains uncertain. We present petrologic and chemical data for a Type B inclusion, EK-459-7-2, that bears features found in both Type B1 and B2 inclusions and likely represents an intermediate between the two types. Detailed studies of more of these intermediate objects may help to constrain models for Type B1 rim formation.

    Behaviorism, cognitivism, and constructivism have led the CAI courseware writing. Situated cognition and learning theory, whose meaning of knowledge can't be derived without specific situation, inherit and develop the leading model of other educational learning theory to CAI courseware writing. Authenticity is the premise of creative situation, which should accord with the objective rule of real life and objects. Situational teaching, which varies from different person, time, and place, should be designed as the most important goal for CAI courseware writing. In addition, creative situation should unify knowledge, science, ideology and interest. Through learning theory guiding CAI courseware writing, CAI courseware has become more accorded with the laws of education to serve the teaching and learning activities better.%行为主义、认知主义、建构主义都曾经指导了CAI课件写作。情境认知与学习理论继承并发展了其他教育学习理论对CAI课件写作的指导,认为:CAI课件中知识的意义不能脱离具体的情境产生。真实性是创设情境的前提,情境创设应符合现实生活场景和事物运动的客观规律,情境性教学应作为CAI课件写作的最重要目标进行设计,要因人、因时、因地而异。此外,情境创设还必须保持情境的知识性、科学性、思想性和趣味性的统一。通过教育学习理论指导CAI课件写作,使CAI课件更符合教育规律,能够更好地服务于教学活动和学习活动。

    For many years the Tien-Shan region* attracts attention of geophysicists and geologists due to complexity and uniqueness of its tectonics. At the turn of the XIX. to the XX. century several destructive earthquakes have occurred in the region with estimated magnitudes between 7 and 8 and two of them even exceeding the magnitude of 8. Our main goal is to investigate the deformation processes responsible for this significant earthquake sequence and the possible interrelation between the single events. Here we present preliminary results of the Chon-Kemin earthquake as an example. On 3rd January 1911 the M 8.3 Chon-Kemin earthquake hit the Tien-Shan region. It is the strongest event in the history of Tien-Shan region for which instrumental recordings are available and one of the strongest intracontinental earthquakes in XX. century. Historical analog data were collected from different seismic archives in European and non-European countries. The data from 20 seismic station were collected, mostly stations at that time had only horizontal components although there are some vertical recordings as well. Preprocessing the analog data brings several difficulties, e.g. limited information on instrument characteristics. Digitization is the most time-consuming part among preprocessing. The quality of seismograms is not always good enough this is why it was necessary to combine different methods of data processing. Since at that time localizations have been done on the base of intensity distributions, the epicenter is poorly determined. Several localizations, differed in the value of up to 80 km, are available. The surface rupture was also estimated in previous studies (about 200 km) and the deformation on the surface can be still observed nowadays, which gives opportunity to calibrate new localization comparing it to the geological data. Thus, we located the earthquake epicenter and determined the magnitude again based on the digitized seismograms. From first motion body wave

    Full Text Available We conducted 2 yr (2005–2007 of in situ meteorological and glaciological observations on the Gregoriev Glacier, a flat-top glacier within the Inner Tien Shan, Kyrgyzstan. Differential GPS surveys reveal a vertical surface deletion at the summit of the glacier. Based on snow density data and an energy-mass balance model, we estimate that the annual precipitation and summer mean temperature required to maintain the glacier in the modern state are 289 mm and −3.85 °C at the glacier summit (4600 m above sea level, a.s.l., respectively. The good agreement between the long-term estimated and observed precipitation at a nearby station in the Tien Shan (292 mm at 3614 m a.s.l. for the period 1930–2002 suggests that the glacier dynamics have been regulated by the long-term average accumulation. The glacier mass-balance, reconstructed based on meteorological data from the Tien Shan station for the past 80 yr, explains the observed fluctuations in glacier extent, particularly the negative mass balance in the 1990s.

    During last years Large Igneous Provinces of the Central Asia were an object of steadfast attention of researchers. It was established that on a formation and development of continental earth crust a great influence was rendered by deep magmatic systems of mantle plumes of various age. Undoubtedly that these global processes of basaltic magmatism had in many respects crucial importance for ecology, climate and life development. Our researches of magmatic associations of the Tien Shan and Junggar have allowed to accumulate a considerable volume of new data on geochronology, geochemistry and physico-chemical parameters of petrogenesis of within-plate basaltic complexes of the Central Asia, which area of distribution covers territory over than 285000 km2. Analysis with the help of 40Ar/39Ar method has shown that the basaltic complexes of the Tien Shan have Cretaceous-Paleogene age (61-76 Ma). Basalts of the Southeast Kazakhstan (North Tien Shan) corresponds to Paleozoic age: 305-312 Ma. Rather close values of 40Ar/39Ar data are received for basalts of the Altynemel Ridge (South Junggar) - 282 Ma. Isotope 40Ar/39Ar dating of basalts of the Alakol site (Junggar) has shown Mesozoic age (186-198 Ma). As a whole, the carried out researches testify to formation of Tien Shan and Junggar within-plate basalt complexes as a result of influence of three plumes, operating in various time: Tarim (282-312 Ma), Junggar (186-198 Ma) and Tien Shan (61-76 Ma). Data on petrochemistry, geochemistry of trace and rare-earth elements and mineralogy shows an enriched plume characteristics (close to OIB) of Mesozoic-Cenozoic basalts and presence of group of Paleozoic rocks close to continental and oceanic plateau basalts. As a whole, successive evolution in time of geodynamics of within-plate basalt magmatism of Tien Shan and Junggar is established. Paleozoic - plateau basaltic magmatism like Siberian traps or oceanic plateau basalts of Ontong Java. Mesozoic - development of more local hot

    Full Text Available A comparative study on cloud parameter estimation among GOSAT/CAI, MODIS, CALIPSO/CALIOP and Landsat-8/OLI is carried out using Laser Radar: Lidar as a truth data. Optical depth, size distribution, as well as cirrus type of clouds are cloud parameters. In particular, cirrus cloud detection is tough issue. 1.38 µm channel is required for its detection. Although MODIS and Landsat-8/OLI have such channel, the other mission instruments, CAI and CALIPSO/CALIOP do not have such channel. As a truth data of cloud parameter, ground based Lidar is used in this comparative study. From the Lidar, backscattered echo signal and depolarization coefficient are obtained as a function of altitude. Therefore, cloud type, vertical profile can be derived from the Lidar data. CALIPSO/CALIOP is satellite based Lidar which allows observation of clouds from space. Although the directions of laser light emissions between CALIPSO/CALIOP and the ground based Lidar are different, their principles are same. Therefore, it is expected that CALIPSO/CALIOP data derived cloud parameters are similar to the ground based Lidar data derived cloud parameters. The experimental results show the aforementioned facts and are useful for improvement of cloud parameter estimation accuracy with several sensor data combinations.

    A significant challenge grows from the ever-increasing demands for the optimization of performance, emissions, fuel economy and drivability. The most powerful technologies in the near future to improve these factors are believed Controlled Auto-Ignition (CAI) in gasoline engine and Gas to Liquid (GTL) as a fuel of Diesel engine. In recent years there has been an increasing trend to use more complex valvetrain designs from traditional camshaft driven mechanical systems to camless electromagnetic or electrohydraulic solutions. Comparing to fixed valve actuation systems, variable valve actuation (VVA) should be powerful to optimize the engine cycle. The matching of valve events to the engine performance and to emission requirements at a given engine or vehicle operating condition can be further optimized to the Controlled Auto-Ignition (CAI) in gasoline engine, which has benefits in NOx emission, fuel consumption, combustion stability and intake throttle load. In case of Diesel engine, the increasing demands for NOx and soot emission reduction have introduced aftertreatment technologies recently, but been in need of basic solution for the future, such as a super clean fuel like Gas to Liquid (GTL), which has benefits in comparability to diesel fuel, independency from crude oil and reduction of CO, THC and soot emissions. Korea looks to the future with these kinds of technologies, and tries to find the possibility for reaching the future targets in the internal combustion engine. (orig.)

    In the period of “Qing Yuan Dang Jin”of Southern Song Dynasty,neo-confucianist Zhu Xi was impeached and dismissed from office.In the meantime,his disciple,Cai Yuanding was imposed a heavy penalty and died in Daozhou because of demotion.On the causes of Cai�s death,many researchers believed that Cai was implicated just because of the powerful minister,Han Tuozhou�s inhibition on Zhu Xi,and he was totally innocent.But based on the scattered historical materials in the relevant peri-od especially from the letters of Zhu Xi in the contemporary period,we can find that Cai was penalized severely partly due to the political background in that period but the hidden and direct cause was be-cause of the event that Cai decided to relocate the Jianyang school to Huguosi because of the Geomantic Omen.This made the political opponents accuse Cai as an excuse and also because the event was related to Geomantic Omen,Zhu Xi and his descendants and disciples were all reluctant to reveal the truth be-hind it,which became the direct reasons of Cai�s death in Daozhou but the reasons were submerged.%南宋“庆元党禁”期间,理学家朱熹因遭劾而落职罢宫观,而其门人蔡元定却受到贬窜道州而死的重罚。对此中缘故,后世大多认定蔡元定只是因权臣韩侂胄为打击朱熹等人而受牵连,纯属“无辜被诬”。但据当时散见诸处之史料,尤其通过辨析朱熹在此前后之书信文字,可证蔡元定受此重罚,虽与当时政治大背景相关,然其直接原因,实在于蔡元定以风水之说主张迁移建阳县学至护国寺址一事,使得政敌们得以借口而窜责蔡元定。也因此重罚事牵涉风水之说,故朱熹、蔡元定及其后人、门生等道学中人皆不愿明言其间,遂使蔡元定贬窜道州之直接原因湮灭不彰。

    Geographic variability of the recent changes of glacier coverage in the Tien Shan Mountains, Central Asia, is assessed using Corona KH-4B satellite photographs for 1968-1971, Landsat 7 ETM+data for 1999-2002, and ALOS/PRISM and AVNIR data for 2006-2008. The four mountain regions investigated (Pskem, Ili-Kungöy, At-Bashy, and SE-Fergana) cover several distributed glacierized areas in the Tien Shan Mountain system, a region that is affected by highly variable local precipitation regimes. Over the 30 years investigated between ~ 1970 and ~ 2000, glacier area decreased by 19% in the Pskem region, 12% in the Ili-Kungöy region, 12% in the At-Bashy region, and 9% in the SE-Fergana region. In the last 7 years (~ 2000 to ~ 2007), glacier area shrank by 5% in the Pskem region, 4% in the Ili-Kungöy region, 4% in the At-Bashy region, and 0% in the SE-Fergana region. Glacier behavior has varied markedly in these regions. The most dramatic glacier shrinkage has occurred in the outer ranges of the Tien Shan Mountains. Recent glacier area loss has resulted from rising summer temperatures. Regional differences of glacier-area changes related to local climate conditions, to the altitudinal distribution of glacier areas, and to the relative proportion of glaciers in different size classes. The observed accelerated glacier shrinkage is expected to have two impacts on the more populated outer ranges: 1) water shortages during summer and 2) increased threat from glacier hazards such as glacier lake outburst floods (GLOFs) and ice avalanches.

    Full Text Available Le statut syntaxique et phonologique des pronoms en créole haïtien et en français a fait l’objet de débats. Les analyses linguistiques classiques du français formulées dans la tradition générative ont proposé une distinction entre les pronoms forts et les pronoms faibles ou ‘clitiques’. Tandis que les pronoms forts se comportent comme des syntagmes nominaux (SN, les clitiques diffèrent de ceux-ci de par leur distribution syntaxique. Ces premières analyses se fondent sur des jugements de grammaticalité et certaines de ces analyses ont été remises en question lorsque des corpus de parole spontanée ont été mis a la disposition des chercheurs et ont permis des analyses quantitatives et phonologiques. La présente étude comparative a pour objectif l’analyse des pronoms personnels du français et du créole haïtien et se fondent sur l’analyse de corpus CHILDES (Demuth & Tremblay, 2008; MacWhinney, 2000 pour le français et un nouveau corpus que nous avons enregistré et transcrit pour le créole haïtien. Les analyses portent sur la distribution syntaxique des pronoms sujets et objets et sur leurs réductions phonologiques. Ces deux sources d’information nous permettent de conclure aux statuts contrastifs des pronoms en créole haïtien qui arborent toutes les caractéristiques des pronoms forts en ce qui concerne leur distribution syntaxique tandis qu’au niveau phonologique ils peuvent être réduits et se comportent donc comme des clitiques phonologiques. En revanche le français comprend des pronoms forts et des pronoms faibles/clitiques qui se distinguent de part leurs trait phonologiques et leur distribution syntaxique.

    We describe a radio-echo sounding (RES) survey for the determination of ice thickness, subglacial topography and ice volume of Glacier No. 1, in Tien Shah,China, using ground-penetrating radar (GPR). Radar data were collected with 100-MHz antennas that were spaced at 4 m with a step size of 8 m. The images produced from radar survey clearly show the continuity of bedrock echoes and the undulation features of the bedrock surface. Radar results show that the maximum ice thickness of Glacier No. 1 is 133 m, the thickness of the east branch of Glacier No. 1 averages at 58.77 m while that of the west branch of Glacier No. 1 averages at 44.84 m. Calculation on ice volume indicates that the ice volume of the east branch of Glacier No. 1 is 51.87 × 106 m3 and that of the west branch of Glacier No. 1 is 20.21 × 106 m3. The amplitude of the undulation of the bedrock surface topography revealed by radar profiles is larger than that of the glacier surface topography, indicating that the surface relief does not directly depend on that of the bedrock undulation in Glacier No. 1, in Tien Shan.

    While the majority of ice core investigations have been undertaken in the polar regions, a few ice cores recovered from carefully selected high altitude/mid-to-low latitude glaciers have also provided valuable records of climate variability in these regions. A regional array of high resolution, multi-parameter ice core records developed from temperate and tropical regions of the globe can be used to document regional climate and environmental change in the latitudes which are home to the vase majority of the Earth's human population. In addition, these records can be directly compared with ice core records available from the polar regions and can therefore expand our understanding of inter-hemispheric dynamics of past climate changes. The main objectives of our paleoclimate research in the Tien Shan mountains of middle Asia combine the development of detailed paleoenvironmental records via the physical and chemical analysis of ice cores with the analysis of modern meteorological and hydrological data. The first step in this research was the collection of ice cores from the accumulation zone of the Inylchek Glacier and the collection of meteorological data from a variety of stations throughout the Tien Shan. The research effort described in this report was part of a collaborative effort with the United State Geological Survey's (USGS) Global Environmental Research Program which began studying radionuclide deposition in mid-latitude glaciers in 1995.

  7. Region-wide glacier mass budgets and area changes for the Central Tien Shan between ~ 1975 and 1999 using Hexagon KH-9 imagery

    The meltwater released by the glaciers in the Central Tien Shan feeds in particular the Tarim River which is the main artery for the oases at the northern margin of the Taklamakan desert. The correct assessment of the contribution of the glaciers' meltwater to the total runoff is hampered by the lack of long-term measurements of glacier mass budgets. Digital terrain models (DTMs) for the different regions in the Central Tien Shan were generated based on ~ 1975 KH-9 Hexagon imagery and compared to the SRTM3 DTM acquired in February 2000. Moreover, glacier area changes for the period ~ 1975-2008 have been measured by means of multi-temporal optical satellite imagery. The geodetic mass budget estimates for a glacierized area of 5000 km2 revealed increasing mass loss east to west and from the inner to the outer ranges. Highest mass loss accompanied by the most pronounced glacier retreat was found for the Ak-Shirak massif with a region-wide mass balance of - 0.51 ± 0.36 m w.e. a- 1 and a rate of area change of - 0.27 ± 0.15% a- 1, whilst moderate mass loss was observed for the Inylchek (0.20 ± 0.44 m w.e. a- 1) and Tomur area (0.33 ± 0.30 m w.e. a- 1) despite partly debris cover. These latter regions also revealed the lowest glacier shrinkage within the entire Central Tien Shan. The total glacier mass loss of 0.35 ± 0.34 m w.e. a- 1 is, however, within the global average whilst the glacier area shrinkage is comparatively low. On average, the investigated glacierized area of ~ 6600 km2 shrank by 0.11 ± 0.15% a- 1 only. We could also identify several surge-type glaciers. The results are consistent with in-situ mass balance measurements for Karabatkak Glacier and previously published results of the Ak-Shirak range proving the suitability of declassified imagery for glacier change investigations. The contribution to the runoff of Aksu River, the largest tributary of the Tarim River, due to glacier imbalance has been determined at ~ 20% for the 1975-2000 period.

  8. Effect of the muon component of cosmic rays on the results of hadron experiments with the big ionization calorimeter (BIC) of the Tien Shan station

    2008-01-15

    A full-scale simulation of the response of the big ionization calorimeter (BIC) at the Tien Shan station to the passage of single protons and muons was performed on the basis of the GEANT4 package in order to estimate the contribution of the muon cosmic-ray component to the generation of unusual events (such as Anti-Centauros), which were recorded by this facility, and to the imitation of the long-flying component, which changes the shape of the average cascade curve. A comparison of the results of this simulation with experimental data reveals that the appearance of Anti-Centauros may be reasonably explained by the contribution of multiple interactions of single muons, but that muon events are insufficient for explaining the change in the shape of the cascade curve (in particular, the emergence of a second maximum).

  9. A 'college of astrology and medicine'? Charles V, Gervais Chrétien, and the scientific manuscripts of Maître Gervais's College.

    2010-06-01

    Considered an institution mainly devoted to astrology and medicine by Simon de Phares and by some historians who believe that he was reliable, the college founded in 1371 by Charles V's first physician, Gervais Chrétien, was in fact primarily dedicated to theological students. It was not before 1377 that there were created there two bursaries for scholares regis, specialising in 'licit mathematical sciences', and two medical fellowships. Yet the influence of the activity of these fellows seems to have been rather moderate and-as far as we can learn from the material still extant, notably from manuscripts that belonged to Maître Gervais' College and to some of its members-this institution was devoted much more to theological studies than to medicine and the quadrivium.

    Earthquakes in low-strain regions and their driving forces are still sparsely studied and understood, and constitute serious first-order research questions. Data acquisition concerning paleo-earthquakes, related hazards, and tectonic activity beyond historical records plays an important role. Such information can be obtained with tools from tectonic geomorphology, geophysics, historic seismicity, and paleo-seismology that should span a variety of time and length scales. The Chon-Kemin Valley in the northern Tien Shan (Kyrgyzstan) is a small, intermontane basin of unknown origin framed by a network of active faults. In the year 1911, the Chon-Kemin earthquake (Mw=8.1) activated fault structures of about 200 km length which also ruptured the surface along the Chon-Kemin Valley and caused numerous landslides and rock avalanches of up to several tens of millions of cubic meters in volume. The Chon-Kemin earthquake was one of a series of strong seismic events that affected the northern Tien Shan between 1885 and 1938. A seismic survey across the Chon-Kemin Valley was conducted to investigate the subsurface velocity structure of the valley and its surrounding faults. Tomographic inversion techniques were applied to first-arrival traveltimes of refracted P waves, and the seismic data were screened for reflection signatures. Additionally, the region was analyzed through paleo-seismological trenching. Tomographic and reflection images identified a shallow basin structure bounded by a set of thrust faults in the south only which - in part - correlate with the surface trace of the rupture. The deformation seems to be distributed in time and space across several sub-parallel fault strands. Synthesis of historical (analog) recordings of this earthquake provide new insights into the source mechanisms and processes.

    High concentrations of total suspended solids (TSS)in coastal and bay areas strongly affect water quality and aquatic ecosystems.Frequent monitoring of spatiotemporal changes of TSS distribution in such areas is indispensable for understanding sediment fluxes and water cycles,and to preserve ecosystem health.This study aimed to identify appropriate and sufficient tools for assessing changes in TSS distribution in Tien Yen Bay in Northem Vietnam,a typical closed bay,which was selected as the study area because of its rich biodiversity.Initially,a physical based model using the reflectance at the sea surface was developed for estimating TSS concentrations from satellite image data,and a model with an exponential function was identified as suitable for the estimation.This model was fitted appropriately to provide a relationship between reflectance from the MODIS/Terra band 1(visible red)after the atmospheric correction and the in situ TSS concentrations at 40 points.Ordinary kriging was then shown to be effective in improving the spatial resolution of the MODIS/Terra image-based estimation of the TSS concentration at a 250 m interval,because it could detect TSS variation in detail,in particular in the local estuaries.TSS distributions derived from 12 MODIS/Terra images from November 2009 to October 2010 clarified seasonal changes in TSS during one year.TSS concentrations were high during summer and lower during fall and winter.Such trends were conformable with the hydrodynamics in Tien Yen Bay.Consequently,the proposed method was more effective for TSS estimation than traditional methods using satellite image data only.

    2003-04-01

    The seismic images of the crust beneath Northern Tien Shan (NTS) are obtained with using of different sets of data and several algorithms for solution of local earthquake tomography problem. The NTS is a very interesting region from geophysical point if view due to high seismic activity caused by interplate collision: Tien Shan and Kazakh. A rectangular region under investigation is constrained by lines 41.90o N - 43.40o N and 73.50o E- 76.50o E. 14661 P and 14436 S wave arrival times recorded 12 seismic stations of the Kyrgyzstan Broadband Network (KNET) from local earthquake in 1991-1999 years are used. In addition, data from 267 local earthquake recorded over a period of about 20 years by a regional arrays of 93 seismographs in NTS are involved in inversions. 1-d optimal velocity models and stations delays are estimated with help of program VELEST (E.Kissling, 1995). Block parameterization of model and ray tracing described by Thurber and Ellsworth (1980) are used for determination of 3-d velocity structure and relocation of events as one of the approaches (programs S.Roecker Sphypit90 and Sphrel3d). Other approach consists in application linear or cubic B spline interpolation of velocity function and ray tracing Um and Thurber (1987) for the solution of forward problem (program C.Thurber et al. Simulps and own program). The data resolution analysis and statistical analysis of models was carried out. Calculated P wave tomographic models were compared with tomographic models S.Roecker et al. (1993), S.Ghose et al. (1998) and T.Sabitova (1996). The main result is the confirmation of existence of different seismic velocity structure beneath Kyrgyz Range and Chu Basin. Using various sets of date and methods for reconstruction velocity model is effective in reveal of more reliable velocity heterogeneities in the domain of research. The author is grateful to dr. I. Kitov for help and to dr. I.Sanina for useful discussion.

    The abundance, biomass, vertical distribution, and taxonomic composition of soil invertebrates (springtails, macrofauna, and termites) were studied in forest formations differing in edaphic and climatic conditions: lowland forests dominated by Lagerstroeomia spp. or Dipterocarpus spp. in the Cat Tien National Park and in a mountain pine (Pinus kesiya) forest on the Da Lat Plateau, southern Vietnam. In the lowland forests, springtails had a relatively low density (10000-12000 ind./m2), but their diversity was high (41-43 species in each forest). The density of large soil invertebrates (without ants and termites) reached 500-700 ind./m2 at a biomass of approximately 30 g/m2 (with earthworms accounting for up to 230 ind./m2 and 19-28 g/m2). Among termites, species of the genera Macrotermes and Odontotermes were dominant. Their total biomass in some areas exceeded 15-20 g/m2. In the mountain pine forest, the total biomass of soil macrofauna was approximately 11 g/m2, the abundance and diversity of springtails were low (7500 ind./m2, 28 species), and wood-destroying species of the genera Schedorhinotermes sp. and Coptotermes sp. dominated among termites.

    Full Text Available Tien-Hsien Liquid (THL is a Chinese herbal mixture that has been used worldwide as complementary treatment for cancer patients in the past decade. Recently, THL has been shown to induce apoptosis in various types of solid tumor cells in vitro. However, the underlying molecular mechanisms have not yet been well elucidated. In this study, we explored the effects of THL on acute promyelocytic leukemia (APL NB4 cells, which could be effectively treated by some traditional Chinese remedies containing arsenic trioxide. The results showed THL could induce G2/M arrest and apoptosis in NB4 cells. Accordingly, the decrease of cyclin A and B1 were observed in THL-treated cells. The THL-induced apoptosis was accompanied with caspase-3 activation and decrease of PML-RARα fusion protein. Moreover, DNA methyltransferase 1 and oncogenic signaling pathways such as Akt/mTOR, Stat3 and ERK were also down-regulated by THL. By using ethyl acetate extraction and silica gel chromatography, an active fraction of THL named as EAS5 was isolated. At about 0.5–1% of the dose of THL, EAS5 appeared to have most of THL-induced multiple molecular targeting effects in NB4 cells. Based on the findings of these multi-targeting effects, THL might be regarding as a complementary and alternative therapeutic agent for refractory APL.

    The 1911 Ms 8.2 Kebin (Chon-Kemin) earthquake is one of the largest intraplate reverse-faulting events to occur historically. It ruptured a 200 km E-W trending zone in the northern Tien Shan. Description of the characteristics of major historic earthquakes, such as the Chon-Kemin event, provide data on the primary deformation and its initial geomorphic degradation, thus informing paleoseismological investigations. Trace geometry and offset distribution are key parameters for the interpretation of the seismotectonic setting and mechanical interaction with other regional structures. The Chon-Kemin earthquake's relationship to other large regional earthquakes, notably the 1887 Ms 7.3 Verny and 1889 Ms 8.3 Chilik events, indicates a strong interaction between structures in this portion of the Tien Shan. We reconnoitered most of the Chon-Kemin rupture belt and associated mass movements and conclude that many of the 1911 features are still well preserved. We emphasized mapping and description of the easternmost 50 km of the rupture, along the Aksu (easternmost) and Chon-Aksu segments. Moving from east to west, 1-3 m high fault scarps and warped Holocene terraces discontinuously cut the piedmonts north and northeast of the town of Anan'evo. The rupture closely follows the mountain front and enters the range just below the Anan'evo landslide (formed in the earthquake). Scarp heights are 2-4 m. West of the Tegermenty River, the left-stepping rupture is continuous and consists of sub parallel strands in places. Between the Sutubulak and the Aksu River crossing, some of the tallest scarps are present, with heights of 6 - 10 m. The generally north-dipping fault zone has low south dips in the near surface as the thrust has driven the hanging wall over the south-sloping piedmont. This change in dip is likely responsible for the formation of E-W extensional faults in the hanging wall. Given the shallow fault dips and tall scarps in this area, 1911 displacement is probably > 10 m

    High-resolution major and trace element (Al, As, Ca, Cd, Co, Cr, Cu, Fe, Li, Mn, Na, Pb, S, Ti, and V) ice core records from Inilchek glacier (5120 m above sea level) on the northwestern margin of the Tibetan Plateau provide the first multi-decadal ice core record spanning the period 1908-1995 AD in central Tien Shan. The trace element records reveal pronounced temporal baseline trends and concentration maxima characteristic of post-1950 anthropogenic emissions. Examination of Pb, Cd and Cu concentrations, along with non-crustal calculation estimates (i.e. excess (ex) and enrichment factor (EF)), reveal that discernable anthropogenic inputs began during the 1950s and rapidly increased to the late-1970s and early 1980s, by factors up to of 5, 6 and 3, respectively, relative to a 1910-1950 means. Pb, Cd and Cu concentrations between the 1950s-1980s are reflective of large-scale Soviet industrial and agricultural development, including the growth of production and/or consumption of the non-ferrous metals, coal and phosphate fertilizers. NOAA HYSPLIT back-trajectory frequency analysis suggests pollutant sources originating primarily from southern Kazakhstan (e.g. Shymkent and Balkhash) and the Fergana Valley (located in Kazakhstan, Uzbekistan and Kyrgyzstan). Inilchek ice core Pb, Cd and Cu reveals declines during the 1980s concurrent with Soviet economic declines, however, due to the rapid industrial and agricultural growth of western China, Pb, Cd and Cu trends increase during the 1990s reflecting a transition from primarily central Asian sources to emission sources from western China (e.g. Xinjiang Province).

  7. Holocene River Dynamics, Climate Change and Floodwater Farming in the Watersheds of the Pamir and Tien Shan Mountains of Inner Asia

    The Ili, Syr Dayra and Amu Dayra rivers of Inner Asia are emerging as critical areas for the development of irrigation-based agriculture in the ancient world. Following research by Russian archaeologists in the 1970s it is evident that these watersheds had flourishing riverine civilizations comparable to those in Mesopotamia and the Indus Valley. But unlike these areas where the relationship between Holocene river dynamics, climate change and floodwater farming is increasingly underpinned by radiometric dating, the alluvial archaeology of Inner Asia is significantly under researched. To address this, a major multi-disciplinary research program was begun in 2011 centred on the Talgar catchment, a south-bank tributary of the Ili river, southeast Kazakhstan. Building on archaeological excavations and surveys conducted over the past 20 years, we have undertaken one of the most detailed investigations of Holocene people-river environment interactions in Inner Asia. River development has been reconstructed over the last 20,000 years and human settlement histories from the Eneolithic to the Medieval period documented. Periods of Holocene river aggradation and high water levels in Lake Balkhash and Aral Sea correspond with cooler and wetter neoglacial episodes while river entrenchment and floodplain soil development are associated with warmer and drier conditions. Floodwater farming in the Talgar river reached its acme in the late Iron Age (400-200 cal. BC) with more than 60 settlement sites and 550 burial mounds. This corresponds to a period of reduced flood flows, river stability and glacier retreat in the Tien Shan headwaters. A new hydroclimatic-based model for the spatial and temporal dynamics of floodwater farming in the Ili, Syr Dayra and Amu Dayra watersheds is proposed, which explains the large scale expansion (down-river) and contraction (up-river) of settlements since the first use of irrigation in the Neolithic through to the late Medieval period.

El presente ensayo tiene como finalidad reflexionar sobre la importancia del humor pedagógico como estrategia de enseñanza aprendizaje en el aula; esto, tomando en cuenta la problemática de desmotivación y aburrimiento que sucede normalmente en la clase. Para plantear si “el enseñar contento y el aprender con alegría” pueden aumentar la eficacia en el proceso de enseñanza-aprendizaje, se abordará cómo, a pesar de las múltiples ventajas que puede aportar el humor en las aulas, se omite su empleo por la existencia de ciertos prejuicios y temores. La idea no es que los docentes hagan el papel de comediantes o payasos, sino la de mediar y acercar la clase de manera pedagógica y didáctica a través del uso del humor, y sobre esto reflexionaba Platón (1992, cuando planteaba que muchas veces ayudaba una broma, en donde la seriedad oponía resistencia. Abstract. This paper studies the importance of humor as a teaching strategy in the classroom, considering the usual lack of motivation and boredom. To analyze whether the “happy teaching and happy learning” may increase effectiveness in the teaching-learning process, the author will discuss how, despite the many benefits it may bring, humor is not used in the classroom due to prejudices and fears. The idea is not for teachers to play the role of a comedian or a clown, but to intervene and get closer to the group with a teaching, didactic purpose through humor. Plato (1992 thought about this; he used to say that sometimes a joke may help, where seriousness put up resistance.

  11. Thermal and chemical evolution in the early Solar System as recorded by FUN CAIs: Part II - Laboratory evaporation of potential CMS-1 precursor material

    We present the results of laboratory experiments in which a forsterite-rich melt estimated to be a potential precursor of Allende CMS-1 FUN CAI was evaporated into vacuum for different lengths of time at 1900 °C. The evaporation of this melt resulted in residues that define trajectories in chemical as well as magnesium, silicon and oxygen isotopic composition space and come very close to the measured properties of CMS-1. The isotopic composition of the evaporation residues was also used to determine the kinetic isotopic fractionation factors [α2,1 (vapor-melt) defined as the ratio of isotopes 2 and 1 of a given element in the evaporating gas divided by their ratio in the evaporating source] for evaporation of magnesium (α25,24 for 25Mg/24Mg), silicon (α29,28 for 29Si/28Si) and oxygen (α18,16 for 18O/16O) from the forsterite-rich melt at 1900 °C. The values of α25,24 = 0.98383 ± 0.00033 and α29,28 = 0.99010 ± 0.00038 are essentially independent of change in the melt composition as evaporation proceeds. In contrast, α18,16 changes from 0.9815 ± 0.0016 to ∼0.9911 when the residual melt composition changes from forsteritic to melilitic. Using the determined values of α25,24 and α29,28 and present-day bulk chemical composition of the CMS-1, the composition of the precursor of the inclusion was estimated to be close to the clinopyroxene + spinel + forsterite assemblage condensed from a solar composition gas. The correspondence between the chemical composition and isotopic fractionation of experimental evaporation residues and the present-day bulk chemical and isotopic compositions of CMS-1 is evidence that evaporation played a major role in the chemical evolution of CMS-1.

  12. Fayalite-rich rims, veins, and halos around and in forsteritic olivines in CAIs and chondrules in carbonaceous chondrites: Types, compositional profiles and constraints of their formation

    Fayalite-rich rims, veins, and halos around and in forsteritic olivines are a wide-spread phenomenon in chondrules, Ca, Al-rich inclusions (CAIs), and single grains in carbonaceous chondrites. The presence of fayalite rod-like crystals and laths in rims, veins, in wall of pores, and as fluffy network bridging neighboring olivines, pyroxenes, feldspars, etc. is strongly suggestive that the fayalitic olivine was formed by condensation presumably from the solar nebula gas. The formation of the fayalitic olivine was probably caused by an increase in the H{sub 2}O/H{sub 2} ratio (to a ratio between 0.1-1) subsequent to condensation of forsterite. At that stage, FeNi inclusions in olivine were also oxidized and fayalitic halos around the metal were then formed Fe diffusion along with addition of SiO{sub 2} from the solar gas or loss of M{sub g}O to the solar gas. The Fa-rich olivine rims and veins display a narrow compositional variation between Fa{sup 34} and Fa{sup 46}. Subsequent to condensation of Fa-rich olivine and oxidation of FeNi metal, Fe diffused in forsterite. This diffusion was probable enhanced due to the presence of point defects in olivine or the formation of a nonstoichiometric phase analogous to laihunite enriched in Al{sub 2}O{sub 3} and Cr{sub 2}O{sub 3}. However, the presence of Al{sub 2}O{sub 3{minus}} and Cr{sub 2}O{sub 3{minus}} rich discrete domains cannot by excluded. Cooling rates calculated by modeling of the diffusion profiles are indicative of rapid cooling subsequent to the condensation of fayalitic olivines. The authors obtain cooling rates ranging from 2000{degree}/day and 10{degree}C/day at an initial temperature of 1200C{degree} and 900C{degree}, respectively.

    Repeated satellite-based inventories of land-cover and land-use, such as Global Landsat Orthorectified data collection (28.5-57 m resolution), are crucial for understanding dynamics of terrestrial ecosystems. However, accurate estimation of dynamics of certain natural and man-made phenomena (mountain glaciers, lakes, urban and agricultural areas) often requires higher resolution remote sensed datasets (with resolution below 10-20 m). In the Northern Eurasia, such datasets are often too expensive or unavailable for a regional study (for example SPOT, TK-350, aerial photography) or span only the last decade (for example Landsat ETM, ASTER, IRS, ALOS/PRISM). This study estimates accuracy and potential of historical Hexagon KH-9 images for generation of a high resolution orthorectified product circa 1976 on a regional scale. The Hexagon KH-9 images were declassified by the U.S. Government in 2002. Although the KH-9 dataset coverage is global, it is particularly rich over the Northern Eurasia where multiple repeat images were acquired for the U.S. Defense Mapping Agency. Using a set of KH-9 images we generated a high quality orthorectified mosaic for the area of Tien Shan mountain system (about 550,000 km2) with resolution of 6-9 m and horizontal accuracy about 9 m. The panchromatic orthophoto mosaic is a unique dataset that for the first time portrays the remote region with such detail and, at the same time, extends the retrospective for more than three decades. The mosaic enabled creation of a glacier inventory for the Tien Shan mountains circa 1976. The Tien Shan case study demonstrated that Hexagon KH-9 images can be used for generation of a land-cover/land-use inventory circa 1976 on regional scales and with high spatial resolution.

    As the representative work of the Chinese culture, the Analects of Confucius has been translated by numerous domestic and overseas scholars. Among the different translation versions, Cai Zhizhong’s Chinese-English Analects is the most typical and best-selling one. The reason lies in that Cai Zhizhong interprets the complicated Confucian thoughts into simple ones through comics, and translates the words of Confucianism into nonverbal symbols. Therefore, this paper, from the perspective of Jakobson’s intersemiotic translation theory, intends to explore that the pictorial symbols can be used to explain the cultural issues in the Analects of Confucius. It is hoped that this study can help people take into consideration of the cross-cultural communication of the Analects of Confucius from diverse dimensions.%作为中国文化的主要代表,《论语》是国内外学者英译最多的典籍之一,在众多英译本中,蔡志忠的中英版《论语》漫画最为畅销。其原因在于蔡志忠以漫画形式将其中深奥的哲理明了化,即用非语言符号系统诠释儒家思想。借助雅各布森的符际翻译理论,指出蔡志忠《论语》漫画中的图像符号作为一种非语言符号,可以成为解释中国典籍外译的手段,从而引导我们对《论语》跨文化传播的多维度思考。

    Spatial repellency of metofluthrin-impregnated polyethylene latticework plastic strips against Aedes aegypti mosquitoes was evaluated. Analysis of environmental factors affecting the efficacy of these strips, such as room temperature, humidity, and house structure, was performed in a residential area in My Tho City, Tien Giang Province, Vietnam. Treatment with the strips at the rate of 1 strip per 2.6-5.52 m(2) (approximately 600 mg per 2.6-5.52 m(2)) reduced the collection of Ae. aegypti resting inside the houses for at least eight weeks. Multiple regression analysis indicated that both increase in the average room temperature and decrease in the area of openings in the rooms that were treated with the strips positively affected the spatial repellency of metofluthrin.

  11. Improved Accuracy of Chlorophyll-a Concentration Estimates from MODIS Imagery Using a Two-Band Ratio Algorithm and Geostatistics: As Applied to the Monitoring of Eutrophication Processes over Tien Yen Bay (Northern Vietnam

    2013-12-01

    Full Text Available Sea eutrophication is a natural process of water enrichment caused by increased nutrient loading that severely affects coastal ecosystems by decreasing water quality. The degree of eutrophication can be assessed by chlorophyll-a concentration. This study aims to develop a remote sensing method suitable for estimating chlorophyll-a concentrations in tropical coastal waters with abundant phytoplankton using Moderate Resolution Imaging Spectroradiometer (MODIS/Terra imagery and to improve the spatial resolution of MODIS/Terra-based estimation from 1 km to 100 m by geostatistics. A model based on the ratio of green and blue band reflectance (rGBr is proposed considering the bio-optical property of chlorophyll-a. Tien Yen Bay in northern Vietnam, a typical phytoplankton-rich coastal area, was selected as a case study site. The superiority of rGBr over two existing representative models, based on the blue-green band ratio and the red-near infrared band ratio, was demonstrated by a high correlation of the estimated chlorophyll-a concentrations at 40 sites with values measured in situ. Ordinary kriging was then shown to be highly capable of predicting the concentration for regions of the image covered by clouds and, thus, without sea surface data. Resultant space-time maps of concentrations over a year clarified that Tien Yen Bay is characterized by natural eutrophic waters, because the average of chlorophyll-a concentrations exceeded 10 mg/m3 in the summer. The temporal changes of chlorophyll-a concentrations were consistent with average monthly air temperatures and precipitation. Consequently, a combination of rGBr and ordinary kriging can effectively monitor water quality in tropical shallow waters.

    Full Text Available Jamais en Éthiopie un chrétien et un musulman ne mangent de viande ensemble. Consommer de la viande qui n’a pas été consacrée à sa propre foi est appréhendé comme un acte hautement sacrilège équivalent à une apostasie. Cet interdit doit être compris dans une perspective comparative large sur les pratiques et les débats qui restreignent la commensalité de la viande entre les chrétiens et les musulmans. Les usages éthiopiens ont accentué cette question pour en faire un interdit puissant, marqueur d’une frontière interreligieuse. Comme toute frontière, cette « frontière carnée » a été le lieu de confrontations, d’aménagements et de transgressions dont les effets ont contribué à la construction de l’espace national éthiopien contemporain.Christians and Muslims in Ethiopia never eat meat together. Consuming meat that was not consecrated to one’s faith is seen as a highly sacrilegious act equal to apostasy. This interdict must be understood in comparative perspective that looks at the restrictions regarding the sharing of meat between Christians and Muslims. Ethiopian customs have emphasized this issue to turn it into a powerful interdict, tracing an inter-religious boundary. Like any boundary, this “dietary boundary” has been the site of confrontations, readjustments and transgressions whose effects have contributed to the building of a contemporary Ethiopian national space.

    Richard E. Clark in his widely published comprehensive studies and meta-analyses of the literature on computer assisted instruction (CAI) has decried the lack of carefully controlled research, challenging almost every study which shows the computer-based intervention to result in significant post-test proficiency gains over a non-computer-based intervention. We report on a randomized study in a medical school setting where the usual confounders found by Clark to plague most research, were carefully controlled. PlanAlyzer is a microcomputer-based, self-paced, case-based, event-driven system for medical education which was developed and used in carefully controlled trials in a second year medical school curriculum to test the hypothesis that students with access to the interactive programs could integrate their didactic knowledge more effectively and/or efficiently than with access only to traditional textual "nonintelligent" materials. PlanAlyzer presents cases, elicits and critiques a student's approach to the diagnosis of two common medical disorders: anemias and chest pain. PlanAlyzer uses text, hypertext, images and critiquing theory. Students were randomized, one half becoming the experimental group who received the interactive PlanAlyzer cases in anemia, the other half becoming the controls who received the exact same content material in a text format. Later in each year there was a crossover, the controls becoming the experimentals for a similar intervention with the cardiology PlanAlyzer cases. Preliminary results at the end of the first two full trials shows that the programs have achieved most of the proposed instructional objectives, plus some significant efficiency and economy gains. 96 faculty hours of classroom time were saved by using PlanAlyzer in their place, while maintaining high student achievement. In terms of student proficiency and efficiency, the 328 students in the trials over two years were able to accomplish the project's instructional

    Young, Edward D.; Dyl, Kathryn A.; Simon, Justin I.

    2012-05-01

    S. Simon et al. incorrectly suggest that in earlier work we claimed there was no Ti3+ in Wark-Lovering rim pyroxenes. In neither the paper by Simon et al. (2005) nor the subsequent paper by Dyl et al. (2011) did we assert that there was no Ti3+ in rim pyroxenes. Rather, we found that many pyroxenes have Ti3+ below detection while others have lower Ti3+/Ti4+ than is typical of CAI interiors, indicating rim formation in a relatively oxidizing environment. Dyl et al. (2011) showed through exhaustive testing that the suggestion by Simon et al. (2007) that EMPA data in the paper by Simon et al. (2005) were flawed is incorrect. Here we consider each point raised in the comment by S. Simon et al. and reiterate that our electron microprobe data and the XANES data of Simon et al. (2007) agree and demonstrate a statistically significant (˜2σ) or greater difference between rim and interior pyroxene Ti3+/Ti4+. We show that the oxidation states of Ti in Wark-Lovering rim pyroxenes, the chemistry of rim pyroxenes, and the modal abundances of rim minerals are best explained by reaction between the CAI and gas that was orders of magnitude more oxidizing than the solar-like gas from which the CAIs originally formed.

    2007-01-01

    We present the observations of a weak MgII absorption system detected at z~0.452 in the UVES high resolution spectrum of the QSO HE0001-2340. The weakest of the two MgII components forming the system shows associated absorptions due to SiI, CaI and FeI observed for the first time in a QSO spectrum. We investigate the nature of this absorber by comparing its properties with those of different classes of absorbers (weak MgII, Damped Ly-alpha systems and local interstellar clouds) and reproducing its ionization conditions with photoionization models. The observed absorber belongs to the class of weak MgII systems on the basis of its equivalent width, however the relative strength of commonly observed transitions deviates significantly from those of the above mentioned absorbers. A rough estimate of the probability to cross such a system with a QSO line of sight is P~0.03. The presence of rare neutral transitions suggests that the cloud is shielded by a large amount of neutral Hydrogen. A detailed comparison of t...

    Full Text Available L’espace libanais est caractérisé par l’absence d’une mémoire collective nationale au profit de plusieurs mémoires sociales portées par les différents groupes identitaires confessionnels et élaborées en fonction des relations conflictuelles ou conviviales qu’ils entretenaient entre eux. Ces mémoires rivalisent entre elles et avec une autre mémoire, construite à partir du début du xxe siècle par des tenants de la coexistence et hissée au rang d’histoire officielle, dans une vaine tentative de promouvoir une vision fédératrice de l’histoire du pays. Les mémoires élaborées autour des affrontements druzo-chrétiens du xixe siècle sont particulièrement illustratives de cette disjonction. Le fait que ce moment fondateur de la question du Liban, soit le produit d’un conflit sanglant est presque passé sous silence dans l’histoire officielle. Un sondage des mémoires communautaires chrétienne et druze pour la période 1820-61 permet de saisir comment ces mémoires vives, elles-mêmes en conflit, ont sapé l’histoire officielle, rendant compte d’un échec des historiens de la coexistence à imposer un récit censuré et pudique comme base d’une mémoire historique commune.

    “听说领先法”英语语法教学模式下课堂教学单一枯燥,但通过对同一句型不断地重复练习,学生能慢慢积累掌握相关知识点。教师的主导地位得以充分发挥。在CAI教学模式下,教师可通过声音、图像等调动学生感官,更好地引导学生学习英语语法知识,但是师生缺乏互动,同样效果不佳。主要讨论将这两种教学模式进行有机结合,扬长避短,即通过CAI英语语法教学的实际运用,充分调动学生作为学习主体的能动性,提高英语语法教学效率。%Traditional audio-lingual teaching mode in English grammar teaching is monotonous and tedious but students can grasp the sentence pattern gradually through practicing repeatedly under this teaching pattern and teacher’s leading role is better reinforced. Teacher can lead students to learn English grammar better by means of audio and video with the help of CAI. However the interaction between teacher and students is fewer compared with the traditional teaching mode. The paper mainly discusses the efficient use of combining with these two methods which have their own advantages and drawbacks in order to strengthen students’ learning initiative and improve teaching efficiency.

Les entités géopolitiques et sociopolitiques qui en résultent évoluent, elles aussi, proportionnellement et rationnellement aux motivations des individus en partance. Ainsi, les exilés forcés rêvaient de retrouver leur chère Haïti, les nouveaux primo-arrivants sont des individus qui cherchent à se ré-enraciner dans un terreau aux airs d’ailleurs. Le diasporique est-il un individu dont l’identité est figée ?

Des dynamiques se font jour montrant que la diaspora est fluctuante comme les identités et les cultures qui la composent.The Push factors of Haitian emigration have completely changed since the late 1950s which marked the beginning of this movement with the Duvalier regime. The geopolitical and sociopolitical entities which result from it are changing as well, in proportion and accordance with the motivations of the people who leave. Thus, the forced exiles dreamt of going back to their dearest Haiti, the latest newly-arrived immigrants are individuals who desire to re-root into a land that sounds like “elsewhere”. Must the diasporic individual’s identity be stable? In this article, a simple survey seeks to shed light on the changing mentalities of young Haitians, examining their identities and cultural choices.  Emerging trends show that diaspora is a flow, not unlike the identities and the cultures of which it is composed.

    Full Text Available HUMAN DIGNITY AFTER TEN YEARS OF TEH CONSTITUTIONAL STATE IN SOUTH AFRICASpeech delivered on 16 March 2004 on the Potchefstroom campus of the North-West UniversityHuman dignity has been the marrow of our Constitution and our constitutional state since 1994. The inherent dignity of man is also a key principle of the Universal Declaration of Human Rights of 1948. The Kantian categorical imperatives continue to provide guidance regarding the meaning of human dignity. At the very least, people are entitled to be regarded as moral subjects and not as objects: as subjects with absolute and inherent worth and therefore also as moral subjects of equal worth.The juridical core of the pathology of apartheid was the extensive and sustained attempt to deprive the majority of South Africans of the right to self-identification and self-determination. It amounted to an inversion of the Kantian imperatives. A reversal of this inversion has been attempted over the past ten years. The Constitution not only elevates human dignity to a specially entrenched value, but also affords it special protection in the context of fundamental rights. It is furthermore a specific consideration in the limitation of rights and in the development of the common law. It applies not only to the state/subject relationship, but also to "horizontal" relationships and it must be taken into account in the interpretation of the Constitution.Constitutional jurisprudence has established that the Constitution is more than a formal document, but that it also represents an objective, normative value system. Thus the foundational norm of human dignity radiates into all areas of the law. The role of human dignity in the interpretation and application of norms applicable to remedial or restitutionary equality, as well as in the achievement of constitutional equilibrium in the "horizontal" operation of the Bill of Rights, has also been established.The realization of human dignity is but in its initial stages: civil society, including educational institutions, are called upon to make their contribution to the process.

    蔡元培提出“以美育代宗教说”是要在宗教精神阙如而儒家礼乐法度业已崩解的现代中国文化场域中,以美育为手段实施国民信仰的重建。审美作为一种精神形式的特殊性和现代中国的社会政治语境使信仰的审美化建构表现出在世俗性与超越性之间徘徊的张力特质,而最终结果往往以牺牲信仰的超越精神为代价,这是与知识分子纠缠于中国与西方、传统与现代的文化现代性心境紧密关联的。%Via his theory of "Aesthetic Education as Substitute for Religion," Cai Yuanpei intended to reconstruct the national belief through aesthetic education in a cultural context where the religious spirit was non - existent and the Confucian rites - music institutions had long collapsed. The uniqueness of aesthetics as mental activities and the socio - political context of modern China determine the tension between the secularity and the transcendence in the aesthetic construction of belief, which often results in the sacrifice of the transcendental spirit. This is closely linked with the state of mind of the intellectuals entangled between China and the west, the traditional and the modem.

    Full Text Available Cet article propose de revenir sur un document aussi exceptionnel que méconnu. Il s’agit du résumé d’un ouvrage (maqāla, aujourd’hui perdu, intitulé « Comment se comporter avec un roi chrétien », et que l’on trouve dans le dictionnaire bio-bibliographique d’Ibn ʿAbd al-Malik. Cette maqāla fut rédigée, par un homme de lettres au service des Almohades, Abū l-Ḥasan ʿAlī Ibn al-Qaṭṭān (m. 1231. C’est la seule source qui ait consigné des indications sur la conduite que devait adopter le souverain lors d’une cérémonie, en présence d’un prince étranger. À ce titre, on y trouve des renseignements essentiels sur le cérémonial almohade ainsi que sur les dilemmes que devaient résoudre le calife : d’un point de vue idéologique, il ne pouvait souffrir aucun autre pouvoir, mais l’impossibilité de mener des opérations d’envergure sur deux fronts à la fois l’amena à composer avec le roi du León. De même, c’est le seul document à avoir fait état d’une divergence de point de vue entre le calife et les intellectuels organiques du système, les Ṭalaba. Ce différend met en lumière des tensions latentes au sommet entre divers serviteurs de l’État, qui n’avaient pas la même forme de légitimité, ni tout à fait les mêmes intérêts.

    The relationship in time and space between CAl formation on the one hand, and chondrule formation on the other is not well understood. It appears that at least compact, coarse-grained CAl were once largely molten. They must have been very depleted in volatiles at that time. However, as now found in Allende they show extensive alteration to volatile rich minerals such as nepheline and sodalite. I have previously argued, partly on the basis of the ubiquitous presence of these vol...

    Computers are increasingly being used in the classroom. An investigation of several educational techniques in a computer-based version of an electronics course is reported. We found that, with a lesson for teaching virtual equality, students learned faster when using a general to specific approach. Students using a simulation of a Schmitt trigger before a qualitative analysis of the circuit performed the analysis faster and with less difficulty than the group performing the analysis first and then exploring the circuit with the simulation. Given a sizable amount of optional material in a computer lesson, most of the electronics students used all of the optional material.

In recent years, there are some dendroclimatological studies in this region, which were focused on the analyses of correlations of chronologies with meteorological data and the precipitation reconstruction. However, the temperature variation history of the region remains unclear.Healthy spruce ( Picea schrenkiana) trees grow in sparse ground vegetation. Spruce trees with little or no apparent evidence of human or other disturbances were selected for sampling. Two cores(5. 15mm diameter) were extracted from each tree in different directions for cross-dating. A total of 62 cores from 31 spruce trees were collected from AKS sampling site(2420 ~2482m a. S. L.,43°12'12. 8" N and 84°47'47. 7" E) in May 2009,which is located in a mountainous area of the Aikendaban region. All of tree-ring samples were dried, mounted, surfaced and cross-dated following standard dendrochronological procedure. Three kinds of tree-ring width data(TRW,EWW and LWW)and five kinds of tree-ring gray values( TRG,EWG,LWG,MXG and MIG)were obtained through a tree-ring image analysis system(WINDENDRO? 2005a) ,which includes a high resolution scanner,a PC computer and a software program.

  11. Quantitative Biostratigraphic Analysis of Central Asia with Implications for the Tien Shan of Kyrgyzstan

    Science.gov (United States)

    McLaughlin, W. N.; Hopkins, S. S.

    2013-12-01

    Central Asia lies at a nexus both in terms of geology and evolutionary biogeography. With the convergence of the Indian and Asian plates creating high rates of deformation over broad regions, shortening of the Paleozoic and Mesozoic basement rocks has created a rich history of late Cenozoic sedimentary basins. In fact, Kyrgyzstan is the most seismically active country in the world. Additionally, Central Asia is a biogeographic crossroads, facilitating the intercontinental migrations of distant faunas from North American, Europe, Africa, and Southern Asia. With such an active geologic and biological evolution, the usefulness of temporal constraints is apparent. However, the continental collision environment has provided few volcanic rocks suitable for radiometric dating. Therefore, while less precise, the biostratigraphic analysis of Central Asia I present is an ideal method for both establishing ages and correlating between disparate basins. The last several decades provided great advancements in quantitative biostratigraphic methods applied to marine microfossils from drill cores. While these newer methods such as RASC (ranking and scaling), its sister program CASC, and CONOP (constrained optimization) provide a clear improvement over older methods such as graphic correlation, they have yet to be applied to terrestrial vertebrate faunas. Graphic correlation only allows comparison between two stratigraphic columns at a time and is heavily weighted by the initial selection of a type section. Both RASC and CONOP compare all stratigraphic sections simultaneously, eliminating type section bias. Previous vertebrate biostratigraphy methods attempted to predict FADs and LADs with the assumption they are generally minimum estimates. RASC instead establishes average stratigraphic ranges for each taxon and with CASC actually provides confidence intervals for each prediction, reducing the potential error resulting from reworking. CONOP generates maximum stratigraphic ranges observed in all sections, yet also includes error bars for the estimates of each biological event such as an extinction or origination. Used in conjunction, RASC, CASC, and CONOP provide both a solid evaluation of land mammal ages or zones for Central Asia and a predictive composite column for new late Cenozoic fossil localities. With a high degree of endemicity and migration, Central Asia cannot rely on the European Neogene Mammal Zones. This study aims to support and evaluate the emerging Asian biostratigraphic and geochronologic framework. With little fossil material currently collected from Kyrgyzstan, this study also sets a temporal framework for future paleontological work. Material is included from countries with much better constrained biostratigraphic records, preferably associated with existing radiometric dates. Specifically included were sites from Asiatic Russia, Mongolia, Western China, India, and Nepal. This geographic range is selected both to preserve the signal of faunas endemic to the Himalayan and Tibetan highlands, but also to provide a large enough sample to account for the well-known problems with the terrestrial fossil record such as high sampling errors and diachrony.

    The Muruntau gold deposit in the Central Kyzylkum, Uzbekistan is one of the largest single gold deposits worldwide. Data available from the literature are reviewed with the aim to (1) integrate the present knowledge on this unique deposit from Russian and English literature; (2) show the considerable progress made in the understanding of the genesis of the Muruntau deposit during the last decades;and (3) point to problems still open for future research. Deposit formation occurred through a multi-stage process involving sedimentation, regional metamorphism including thrusting, magmatism with for-mation of hornfels aureoles and several stages of hydrothermal activity. According to recent knowledge, synsedimentary or pure metamorphic formation of gold mineralization seems unlikely. The role of granite magmatism occurring roughly within the same time interval as the main hydrothermal gold precipitation remains uncertain. There are no signs of interaction of matter between the magma(s) and the hydrothermal system(s). On the other hand, there was an intense, high-temperature (above 400 ?C) fluid e wall rock interaction resulting in the formation of gold-bearing, cone-like stockworks with veins, veinlets and gold-bearing metasomatites. Several chemical and isotope indicators hint at an involvement of lower-crustal or mantle-related sources as well as of surface waters in ore formation. Deposit for-mation through brecciation involving explosion, hydrothermal or tectonic breccias might explain these data. Further investigations on breccia formation as well as on the exact timing of relevant sedimentary, metamorphic, magmatic and hydrothermal events are recommended.

    En este artículo se describen las observaciones realizadas en el trabajo con distintos grupos de la comunidad, sobre el tema de la homosexualidad. Conviene aclarar que con el término homosexualidad se hace referencia tanto al hombre como a la mujer, esto por cuanto dicho término procede del griego ''homo'' que significa "mismo" "igual" no de la palabra latina ''homo'' que significa hombre. En los talleres que se realizan sobre sexualidad humana, el tema de homosexualidad es casi siempre solicitado por los participantes, pero el grupo en que más se registra esta necesidad es en el de los maestros. Al iniciar la discusión la sola mención de la palabra produce reacción y no propiamente de aceptación, en el lenguaje no verbal de los participantes se perciben gestos de desagrado, o el chiste un poco mordaz que luego se traduce en palabras y expresiones más concretas que muestran lo que esa comunicación ha tratado de transmitir.

    1995-01-01

    Since the nurse emerged as a qualified professional to attend human beings, the role which always characterized his/her action was assistance. Already since the foundation of the first nursing school, teaching aimed at developing the student to dispense nursing care necessary for the patient's assistance. When the nurse started to perform their activities in nosocomial and community institutions, the need for someone who would be responsible for the organization, coordination and control of nursing personnel and the Nursing Unit itself, in short, someone who would head the services became apparent. At present, the professional role of the nurse is changing regarding his/her overall assistance to the patient, caring directly, determining and/or carrying out nursing assistance necessary for the patient's health, maintenance or recovery. In this manner, it is necessary for nurses to use tools of administration science such as planning, decision making, and planned changes in order to be able to provide the nursing assistance with quality. Thus, this study aims at helping the development of the nurse's interest in computer during the teaching-learning process, motivating the search for knowledge in computerized sources. We intended to offer the opportunity for discussion and reflection on problems of nosocomial nursing practice, favoring interchange of theory and practice. The system is being developing using ToolBook Live Software to be run in Windows environment. The content of the subject allow the user (student or professional nursing) to choose the most correct answers to questions in the knowledge area. In this case, to discuss nursing administration issues through the study of practical situations is possible, such as the opportunity the verify the performance in tests.

  20. The Formation of Boundary Clinopyroxenes and Associated Glass Veins in Type B1 CAIs

    We used focused ion beam thin section preparation and scanning transmission electron microscopy (FIB/STEM) to examine the interfacial region between spinel and host melilite for three spinel grains, two from the mantle and one from the core of an Allende type B1 inclusion, and a second pair of spinel grains from a type B1 inclusion from the Leoville carbonaceous chondrite. The compositions of boundary clinopyroxenes decorating spinel surfaces are generally consistent with those of coarser clinopyroxenes from the same region of the inclusion, suggesting little movement of spinels between mantle and core regions after the formation of boundary clinopyroxenes. The host melilite displays no anomalous compositions near the interface, and anorthite or other late-stage minerals are not observed, suggesting that crystallization of residual liquid was not responsible for the formation of boundary clinopyroxenes. Allende spinels display either direct spinel-melilite contact or an intervening boundary clinopyroxene between the two phases. In the core, boundary clinopyroxene is mantled by a thin (1-2 {micro}m thick) layer of normally zoned (X{sub Ak} increasing away from the melilite-clinopyroxene contact) melilite with X{sub Ak} matching that of the host melilite at the melilite-melilite contact. In the mantle, X{sub Ak} near boundary spinels is constant. Spinels in a Leoville type B1 inclusion are more complex with boundary clinopyroxene, as observed in Allende, but also variable amounts of glass ({approx}1 {micro}m width), secondary calcite, perovskite, and an unknown Mg-, Al-, OH-rich and Ca-, Si-poor crystalline phase that may be a layered double hydrate. Glass compositions are consistent to first order with a precursor consisting mostly of Mg-carpholite or sudoite with some aluminous diopside. One possible scenario of formation for the glass veins is that open system alteration of melilite produced a porous, hydrated aggregate of Mg-carpholite or sudoite + aluminous diopside that was shock melted and quenched to a glass. The unknown crystalline phase may be a shocked remnant of the precursor phase assemblage but is more likely to have formed later by alteration of the glass. Calcite appears to be an opportunistic fracture filling that postdated all major shock events. Boundary clinopyroxenes probably share a common origin with coarser-grained pyroxenes from the same region of the inclusion. In the mantle, these crystals may represent clinopyroxene crystallized in Ti-rich liquids caused by the direct dissolution of perovskite and an associated Sc-Zr-rich phase or as a reaction product between dissolving perovskite and liquid (i.e., indirect dissolution of perovskite). In the core, any perovskite and associated Ti-enriched liquids that may have originally been present disappeared before the growth of boundary clinopyroxene.

    Oak Ridge National Laboratory is developing a prototype computer aided instruction package for the Navy Management Systems Support Office. This report discusses the background of the project and the progress to date including a description of the software design, problems encountered, solutions found, and recommendations. The objective of this project is to provide a prototype that will enhance training and can be used as a shipboard refresher and retraining tool. The prototype system will be installed onboard ships where Navy personnel will have ready access to the training. The subsequent testing and evaluation of the prototype could provide the basis for a Navy-wide effort to implement computer aided instruction. The work to date has followed a rigorous structured analysis methodology based on the Yourdon/DeMarco techniques. A set of data flow diagrams and a data dictionary are included in the appendices. The problems encountered revolve around requirements to use existing hardware, software, and programmer capabilities for development, implementation, and maintenance of the instructional software. Solutions have been developed which will allow the software to exist in the given environment and still provide advanced features not available in commercial courses.

Two questionnaires were used: the first was applied to a sample of young people aged between 18 and 24 years, who were planning to make a decision about your future career, and the second was applied to students of the mastery in bibliotecology from the University of Sheffield,who theirs had already chosen that program as career. The questionnaires inquired by the impressions of people about bibliotecology as a career and realized that presented barriers when entering the profession. The study found that both the lack of knowledge about the implications of the role of the librarian, as the lack of knowledge of the choice of bibliotecology as a career, influence the negative perception of young people to become librarians. Students in the mastery in bibliotecology identified a number of obstacles that interfered with access to the profession and suggested possible solutions to address this situation. The bibliotecology does not appeal to young people because of the impressions they have about it. Therefore, in order to eradicate the misconceptions held about this race, librarians should promote their work as more knowledge of bibliotecology, lead to this becoming a more attractive option for young people.

Transition of a non-sustainable society towards a sustainable society has become one of the main issues to be studied. In the first two chapters historical and organizational aspects of IVEM are discussed. In the rest of the chapters attention is paid to recently completed and current research projects. In the chapters 3 to 14 the areas of interest of a subsection of IVEM, the working group Energy and Materials, are dealt with: use of models in the environmental sciences, life cycle analysis, economic activity and energy consumption, patterns in electricity consumption, reorganized public utility sector, modelling of supply and demand of electricity, the role and contribution of nuclear energy, metals in the environment, ECCO (Enhancement of Capital Creation Options) and the Resource Accounting method, physical constraints of the transition towards a sustainable society, recycling and carbon cycle management, and the sustainable use of packing materials. The areas of interest of another IVEM working group (Environment, Perception and Behavior) are discussed in the chapters 15, 16 and 17: exposure to noise and odor pollution, local environment quality, and behavioral change with regard to mobility and the environment. In the chapters 18 and 19 attention is paid to the areas of interest of the IVEM working group Agriculture and Nature: basics of the environmental problemacy and the relation between nature and agriculture. The next five chapters (20 to 24) deal with multidisciplinary projects. In chapter 25 sociological and psychological aspects in environmental studies are discussed.

    Directory of Open Access Journals (Sweden)

    J. Aaron Simmons

    2017-02-01

    Full Text Available In this essay, I offer an existential-phenomenological consideration of what it might look like to live joyfully after losing social hope. Using the example of the widespread hopelessness that many are feeling in light of the election of Donald Trump, I suggest that the danger of losing hope is that we can also lose our selfhood in the process. In order to develop a conception of “eschatological hope” that would be resistant to the loss of such social and political expectations, I draw specifically on Søren Kierkegaard’s notion that “the expectancy of faith is victory,” and Jean-Louis Chrétien’s idea of “the unhoped for,” in order to develop a model of hope that remains when it seems like all other hope has been lost. Rather than being overcome by anxiety about the future, eschatological hope fosters joy in the present.

    This paper looks at glacier area change in the Tomur Peak for the 1964/71–2000 and 2000–2011 periods. The results show that the total area of the selected 78 glaciers has decreased from 555.45 km2 in 1964/71 to 530.39 km2 in 2000, and further reduced to 521.89 km2 in 2011. Overall, the selected glaciers have lost 4.50% of their surface area between 1964/71 and 2000, and have lost 1.60% more between 2000 and 2011. The area reduction rate of the 78 glaciers increased from 0.12%/a during 1964/71–2000 to 0.13%/a during 2000–2011. In addition, this paper describes a method for estimating the ice surface elevation change using the SRTM (2000) and elevation data generated from topographic maps (1964/71) to quantify the ice thickness change for the 1964/71–2000 period. The surface elevation for about 73.50% of grid area decreased, mostly in the glacier ablation zone. The overall average thickness loss is 22.35 m which yields an annual loss of 0.60 m/a.

    Full Text Available El Tribunal Supremo ha condenado a varios obstetras por informar que el cordón umbilical tenía los tres vasos, desactivando así la búsqueda de enfermedades fetales que la arteria umbilical única (AUU habría desencadenado. La condena será éticamente correcta si la AUU está realmente asociada a tales enfermedades. En la población general se detecta un caso de AUU en cada 320 fetos estudiados ecográficamente. En el 68 % de esas detecciones se tratará de un hallazgo aislado, pero aún así aumenta el riesgo de parto prematuro, de peso bajo y de mortalidad perinatal. Por otra parte, el 17 % de estos fetos tendrán, además de la arteria única, cromosomopatías y el 31 % malformaciones anatómicas. Concluyendo, la AUU es realmente un marcador cardinal de riesgo de trastornos fetales, que debe buscarse activamente durante el seguimiento ecográfico del embarazo.

    Estudios previos en Buenos Aires reportaron altas prevalencias de HIV entre HSH, con valores que oscilan entre 9 y 14% durante casi 10 años de continuo testeo. El objetivo principal de este estudio fue la evaluación de factores relacionados al comportamiento de alto riesgo para transmisión del HIV entre HSH entre los que se incluyen el conocimiento y factores emocionales, socioculturales y ambientales. Por otro lado se realizó la estimación de prevalencia e incidencia de HIV utilizando RDS (Respondent Driven Sampling), así como la presencia de otras infecciones de transmisión sexual. Por último se evaluaron los hábitos de testeo para HIV indagando que factores facilitan o impiden su realización. El estudio constó de dos fases, en primer lugar una fase cualitativa y posteriormente una fase cuantitativa con una duración total de 4 años y medio. Durante la fase cualitativa se realizaron 44 entrevistas individuales en profundidad, 8 grupos focales y 10 observaciones etnográficas (hoteles, baños públicos ("teteras"), cines pornográficos, fiestas privadas, dark rooms y discotecas). Durante la fase cuantitativa del estudio se realizó el reclutamiento de 500 participantes que provinieron de la Ciudad Autónoma de Buenos Aires, así como del Gran Buenos Aires.

    Resumen Estudios previos en Buenos Aires reportaron altas prevalencias de HIV entre HSH, con valores que oscilan entre 9 y 14% durante casi 10 años de continuo testeo. El objetivo principal de este estudio fue la evaluación de factores relacionados al comportamiento de alto riesgo para transmisión del HIV entre HSH entre los que se incluyen el conocimiento y factores emocionales, socioculturales y ambientales. Por otro lado se realizó la estimación de prevalencia e incidencia de HIV utilizando RDS (Respondent Driven Sampling), así como la presencia de otras infecciones de transmisión sexual. Por último se evaluaron los hábitos de testeo para HIV indagando que factores facilitan o impiden su realización. El estudio constó de dos fases, en primer lugar una fase cualitativa y posteriormente una fase cuantitativa con una duración total de 4 años y medio. Durante la fase cualitativa se realizaron 44 entrevistas individuales en profundidad, 8 grupos focales y 10 observaciones etnográficas (hoteles, baños públicos (“teteras”), cines pornográficos, fiestas privadas, dark rooms y discotecas). Durante la fase cuantitativa del estudio se realizó el reclutamiento de 500 participantes que provinieron de la Ciudad Autónoma de Buenos Aires, así como del Gran Buenos Aires.

    The evolution of Northern Inylchek Glacier and its proglacial lake - Upper Lake Merzbacher - during its 1996 surge and the surrounding decades is analyzed with remote sensing imagery. Overall retreat of the glacier from 1943 to 1996 enlarged the lake to 4 km long and ≈ 100 m deep. The surge in 1996 initiated between 12 September and 7 October and advanced the glacier by 3.7 km to override most of Upper Lake Merzbacher. The surge phase probably ended in December 1996 and involved mean flow velocities across the lower trunk of the glacier that reached 50 m d- 1 over a 32-day period. Water displaced by the surge from Upper Lake Merzbacher, totalling 1.5 × 108 m3 in volume, accelerated filling of Lower Lake Merzbacher downvalley and helped trigger this marginal ice-dammed lake to outburst in a jökulhlaup around late November/early December. The characteristics and duration of the surge render it as similar to temperate glacier surges elsewhere. It may have been facilitated by low basal friction caused by water-saturated sediments in the upper lake bed. Furthermore, bathymetric measurements show that the surge evacuated much sediment into the upper lake, causing its depth to reduce from 20 to 30 m in 1996 to 8 m by 2005 and 2 m by 2011; the corresponding deposition rates imply glacier-catchment specific mean sediment yields of 1.4 to 3.4 × 103 Mg km- 2 a- 1 in the years after the surge. Our study documents novel interactions within a cascade system of glaciers and lakes that exhibits surging and outburst-flood behavior.

  11. Natural gas diffusion model and diffusion computation in well Cai25 Bashan Group oil and gas reservoir

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Natural gas diffusion through the cap rock is mainly by means ofdissolving in water, so its concentration can be replaced by solubility, which varies with temperature, pressure and salinity in strata. Under certain geological conditions the maximal solubility is definite, so the diffusion com-putation can be handled approximately by stable state equation. Furthermore, on the basis of the restoration of the paleo-buried history, the diffusion is calculated with the dynamic method, and the result is very close to the real diffusion value in the geological history.

    Full Text Available The present paper is dedicated to analyze the political and cultural discourse identified to the Chilean New Song Movement through the musical work of the singer, composer and theater director Víctor Jara (1932-73. Despite his premature death - due to the coup of 1973 - Jara left a varied artistic legacy which constitutes a privileged source for thinking about the Chilean context of the 1960s and 1970s, a period marked by the strong presence of social movements that had as background the growing of the political polarization. Affiliated to the Communist Party, the musician used the communicative and expressive potential of music to defend the need to promote structural political changes in the country, which necessarily pass through the sphere of culture. Asking for the presence of identity elements in his musical work, we will analyze the dialogue established by the artist with the national political context, indicating the heterogeneity of the repertoire enclosed under the term Chilean New Song Movement.

    2000-01-01

    Full Text Available Las matemáticas han jugado un papel decisivo en el desarrollo del pensamiento, en particular del económico, convirtiéndose en las últimas décadas en un instrumento de trabajo indispensable en la elaboración de modelos teóricos capaces de explicar relaciones económicas cada vez más complejas. No obstante, parece lógico que aún valorando positivamente las teorías más abstractas, se deba evitar un uso abusivo de sofisticados modelos matemáticos siempre que se manifiesten como una especie de “fuga técnica de la realidad” o contribuyan a propagar una visión deformada de la economía. La relación entre ambas se basa no tanto en que los resultados concretos que hoy se conocen en matemáticas tengan su análogo o no en la ciencia económica, sino en que la metodología que usa la matemática desde sus principios no es fundamentalmente distinta de la que vienen usando los economistas teóricos para resolver sus problemas. En este trabajo, después de la introducción hacemos un breve recorrido histórico por las matemáticas y su relación con otras ciencias, para centrar posteriormente su atención en el desarrollo de la ciencia económica. Finalizamos destacando algunas teorías matemáticas que por sus características, pueden ayudar a resolver algunos de los problemas actuales de la ciencia económica.

    Full Text Available Destruction at least ten times emphasized – an interpretation of 'Kraak die aardbol langs ’n naat' ('Cracking the earth along the seam' by Wilma Stockenström In this article the value of syntactical analysis in the interpretation of a poem is investigated from the premise that emphasis can be effected inter alia in the following ways: (a by contravening certain rules that apply in standard language usage in order to compose grammatical sentences, b the exploitation of parallel syntactical structures, and c the relationship between sentence unit and line, and line and/or stanza. These theoretical points of departure form the basis of the syntactical analysis of “Kraak die aardbol langs ’n naat” (Wilma Stockenström, in which there are numerous deviations from the expected, normal and usual ways of constructing sentences. It is by these means that the semantic values gain prominence: the attention is drawn to the deviating behaviour of mankind continuing to destruct the earth until nothing remains. It is evident that the repeated use of irony and the satirical tone of this poem also contribute to persuade the reader to behave in a way opposite to that depicted in the poem. In this way the value of a syntactical analysis of this poem is illustrated. By uncovering the micro-structures (syntactical units within the (macro- structure (the poem, underlying patterns and the place of humanity in the universe can be better understood. In this way the analysis of this poem is then linked to the field of ecocriticism.

    Six actinomycetes, CAI-13, CAI-85, CAI-93, CAI-140, CAI-155 and KAI-180, isolated from six different herbal vermi-composts were characterized for in vitro plant growth-promoting (PGP) properties and further evaluated in the field for PGP activity in rice. Of the six actinomycetes, CAI-13, CAI-85, CAI-93, CAI-140 and CAI-155 produced siderophores; CAI-13, CAI-93, CAI-155 and KAI-180 produced chitinase; CAI-13, CAI-140, CAI-155 and KAI-180 produced lipase; CAI-13, CAI-93, CAI-155 and KAI-180 produced protease; and CAI-13, CAI-85, CAI-140 and CAI-155 produced ß-1-3-glucanase whereas all the six actinomycetes produced cellulase, hydrocyanic acid and indole acetic acid (IAA). The actinomycetes were able to grow in NaCl concentrations of up to 8%, at pH values between 7 and 11, temperatures between 20 and 40 °C and compatible with fungicide bavistin at field application levels. In the rice field, the actinomycetes significantly enhanced tiller numbers, panicle numbers, filled grain numbers and weight, stover yield, grain yield, total dry matter, root length, volume and dry weight over the un-inoculated control. In the rhizosphere, the actinomycetes also significantly enhanced total nitrogen, available phosphorous, % organic carbon, microbial biomass carbon and nitrogen and dehydrogenase activity over the un-inoculated control. Sequences of 16S rDNA gene of the actinomycetes matched with different Streptomyces species in BLAST analysis. Of the six actinomycetes, CAI-85 and CAI-93 were found superior over other actinomycetes in terms of PGP properties, root development and crop productivity. qRT-PCR analysis on selected plant growth promoting genes of actinomycetes revealed the up-regulation of IAA genes only in CAI-85 and CAI-93.

Our measurements...... demonstrate the presence of four distinct fossil Be/ Be isochrons, lower in the FUN-CAIs than in the canonical CAIs, and variable within these classes. Given that FUN-CAI precursors escaped evaporation-recondensation prior to evaporative melting, we suggest that the Be/ Be ratio recorded by FUN......-CAIs represents a baseline level present in presolar material inherited from the protosolar molecular cloud, generated via enhanced trapping of galactic cosmic rays. The higher and possibly variable apparent Be/ Be ratios of canonical CAIs reflect additional spallogenesis, either in the gaseous CAI...

    The present study was developed to evaluate multiparous sow reproductive performance and backflow in post-cervical artificial insemination (post-CAI) using a reduced number of sperm than in cervical artificial insemination (CAI). The experimental groups were divided into sows inseminated by: 1) cervical artificial insemination (CAI): 3×10(9) spermatozoa/80 ml; 2) post-CAI: 1.5×10(9) spermatozoa/40 ml (post-CAI 1); 3) post-CAI using 1×10(9) spermatozoa/26 ml (post-CAI 2). Post-CAI 1 reproductive parameters were similar to those of post-CAI 2 (except for live born litter size which was greater in post-CAI 1) and better than for the CAI group (pinsemination dose incubated inside a colostomy bag (sperm quality control group). The present study shows that the use of post-CAI (either post-CAI 1 or 2) in field conditions can be recommended because the efficiency is similar (in the case of post-CAI 2) or higher (post-CAI 1) than when using the traditional method (CAI), representing a reduction cost.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Recentemente, o uso de chás medicinais - infusões, decoctos, tisanas, tinturas - ou medicamentos de origem vegetal vem sendo retomado de maneira sistemática e crescente na profilaxia e tratamento das doenças, ao lado da terapêutica convencional, na maioria dos países ocidentais. A presente revisão objetiva analisar as principais plantas que serviram como base de progresso para a moderna terapêutica anestesiológica através de sua utilização como modelos moleculares para síntese orgânica na moderna química fina de ponta, bem como fornecer mais embasamento sobre benefícios, potenciais efeitos adversos, interações e risco de efeitos colaterais que possam afetar o ato anestésico no paciente cirúrgico usuário habitual de fitoterapia. CONTEÚDO: Considerações anestesiológicas selecionadas são discutidas focalizando uma pequena revisão sobre ervas medicinais mais populares que foram essenciais no desenvolvimento de uma farmacologia anestesiológica e, ainda, as potenciais interações de plantas medicinais usadas por pacientes para tratar suas doenças ou controlar seus sintomas com drogas sintéticas usadas na anestesia. CONCLUSÕES: Enquanto a Medicina especializada fascina-se cada vez mais com a tecnologia avançada de novos fármacos e de fantásticos monitores, cresce em vários países o número de pacientes que desejam uma abordagem mais holística com rejeição dos modernos métodos de tratamento, optando por chás, meditações, dietas vegetarianas, anti-oxidantes, entre outros. Cabe ao anestesiologista avaliar quanto o conhecimento de farmacognosia e de farmacobotânica pode ajudá-lo na prática anestésica e, principalmente, na segurança de seu paciente.JUSTIFICATIVA Y OBJETIVOS: Recientemente, el uso de tés medicinales - infusiones, decocciones, tisanas, tinturas - o medicamentos de origen vegetal viene siendo retomado de manera sistemática y creciente en la profilaxis y tratamiento de las enfermedades al lado de la terapéutica convencional en la mayoría de los países occidentales. La presente revisión objetiva analizar las principales plantas que servirán como base de progreso para la moderna terapéutica anestesiólogica a través de su utilización como modelos moleculares para síntesis orgánica en la moderna química fina de punta, bien como suministrar más fundamento sobre beneficios, potenciales efectos adversos, interacciones y riesgo de efectos colaterales que puedan afectar el acto anestésico en el paciente cirúrgico usuario habitual de la fitoterapia. CONTENIDO: Son discutidas las consideraciones anestesiológicas seleccionadas, focalizando una pequeña revisión sobre hierbas medicinales más populares que fueron esenciales en el desenvolvimiento de una farmacología anestesiológica y aún, las potenciales interacciones de plantas medicinales usadas por pacientes para tratar sus enfermedades o controlar sus síntomas con drogas sintéticas usadas en la anestesia. CONCLUSIONES: En cuanto la Medicina especializada se fascina cada vez más con la tecnología avanzada de nuevos fármacos y de fantásticos monitores, crece en varios países el número de pacientes que desean una abordaje mas holística con rechazo de los modernos métodos de tratamiento, optando por tés, meditaciones, dietas vegetarianas, anti-oxidantes, entre otros. Cabe al anestesiologista evaluar cuanto el conocimiento de farmacognosia y de farmacobotánica puede ayudarlo en la práctica anestésica y, principalmente, en la seguridad de su paciente.BACKGROUND AND OBJECTIVES: Recently, the use of medicinal teas - infusions, decoction, tisanes, dyeings - or drugs of vegetal origin are being systematically and increasingly revived to prevent and treat diseases together with conventional medicine in most Western countries. This review aimed at analyzing major herbs that were the basis for the progress of modern anesthetic therapy through their use as molecular models for organic synthesis in fine leading edge modern chemistry, as well as shedding more light on the advantages, potential adverse effects, interactions and risks for side-effects which may affect anesthesia in surgical patients users of phytotherapy. CONTENTS: Selected anesthesiologic considerations are discussed focusing a brief review of popular herbs essentials on the development of anesthetic pharmacology and the potential drug-herb interactions between synthetic drugs used in anesthesia and the medicinal herbs used by patients in their illness and symptoms management. CONCLUSIONS: While specialized Medicine is increasingly fascinated by the advanced technology of new drugs and fantastic monitors, there is an increasing trend in several countries for a more holistic approach and rejection of new treatment methods, with an option for teas, meditation, vegetarian diets and anti-oxidants, among others. It is the anesthesiologist’s role to evaluate how much pharmacognosy and pharmacobotany knowledge may help him in the anesthetic practice and, especially, in patients safety.

The flood killed three people and numerous livestock, destroyed infrastructure, and devastated potato and barley crops as well as pastures. Tuurasuu village and a downstream reservoir on the Zyndan river escaped heavy damage because the main flood was diverted toward the Tong river. RTK-GPS and satellite data (Landsat 7 ETM+, ALOS/PRISM, and ALOS/AVNIR-2 reveal that the flood reduced the lake area from 0.0422 km2 to 0.0083 km2, discharging 437 000 m3 of water. This glacier lake was not present in a Landsat 7 ETM+ image taken on 26 April 2008. It formed rapidly over just two and half months from early May to the late July, when large amounts of snow and glacier melt water became trapped in a basin in the glacier terminus area, blocked by temporary closure of the drainage channel through the terminal moraine that included much dead-ice. In the same mountain region, most other glacier-lake expansions were not particularly large during the period from 1999–2008. Although events like the w-Zyndan glacier lake outburst occur infrequently in the high Central Asian mountains, such fast developing, short-lived lakes are particularly dangerous and not easy to monitor using satellite data. Appropriate measures to protect against such lake outburst hazards in this region include educating residents on glacier hazards and monitoring techniques, providing frequently updated maps of glacier lakes, and planning and monitoring land-use, including house locations.

    Full Text Available En el presente trabajo se ha valorado la posible reducción de la tasa de recidivas en la pancreatitis aguda biliar mediante el tratamiento con ácido ursodeoxicólico (AUC entre el episodio de pancreatitis y el momento de la colecistectomía. Se estudiaron 72 primeros episodios consecutivos de pancreatitis aguda biliar, en pacientes no colecistectomizados, seguidos hasta la cirugía. Los casos se dividieron en grupo A (n = 30, tratados al alta con AUC 10 mg/kg/día, hasta la cirugía, y grupo B o control (n = 42. Se evaluaron las diferencias entre ambos grupos en cuanto a características del paciente, gravedad de la pancreatitis, características de la litiasis y demora hasta la cirugía. Analizamos las recidivas de la pancreatitis entre los grupos con y sin AUC. En el grupo con AUC comparamos la duración del tratamiento entre los pacientes con y sin recidiva de la pancreatitis. Los dos grupos no mostraron diferencias significativas en cuanto a ninguno de los parámetros estudiados. Registramos 7/30 (23,3% recidivas en el grupo AUC, frente a 9/42 (21,4% recidivas en el control (p = 0,85. Dentro del grupo AUC, la duración del tratamiento fue similar entre los casos que recidivaron: 4,9±4,5 meses y los no recidivados: 4,4±1,9 meses (p = 0,78. En nuestra experiencia, el empleo de AUC hasta el momento de la colecistectomía no reduce la incidencia de recidiva en los pacientes tras un primer episodio de pancreatitis aguda biliar. La duración del tratamiento con AUC tampoco parece relacionarse con la aparición o no de recidivas.

    2012-04-01

    Full Text Available Background: in 21st century, endoscopic study of the small intestine has undergone a revolution with capsule endoscopy and balloon-assisted enteroscopy. The difficulties and morbidity associated with intraoperative enteroscopy, the gold-standard in the 20th century, made this technique to be relegated to a second level. Aims: evaluate the actual role and assess the diagnostic and therapeutic value of intraoperative enteroscopy in patients with obscure gastrointestinal bleeding. Patients and methods: we conducted a retrospective study of 19 patients (11 males; mean age: 66.5 ± 15.3 years submitted to 21 IOE procedures for obscure GI bleeding. Capsule endoscopy and double balloon enteroscopy had been performed in 10 and 5 patients, respectively. Results: with intraoperative enteroscopy a small bowel bleeding lesion was identified in 79% of patients and a gastrointestinal bleed-ing lesion in 94%. Small bowel findings included: angiodysplasia (n = 6, ulcers (n = 4, small bowel Dieulafoy's lesion (n = 2, bleed-ing from anastomotic vessels (n = 1, multiple cavernous hemangiomas (n = 1 and bleeding ectopic jejunal varices (n = 1. Agreement between capsule endoscopy and intraoperative enteroscopy was 70%. Endoscopic and/or surgical treatment was used in 77.8% of the patients with a positive finding on intraoperative enteroscopy, with a rebleeding rate of 21.4% in a mean 21-month follow-up period. Procedure-related mortality and postoperative complications have been 5 and 21%, respectively. Conclusions: intraoperative enteroscopy remains a valuable tool in selected patients with obscure GI bleeding, achieving a high diagnostic yield and allowing an endoscopic and/or surgical treatment in most of them. However, as an invasive procedure with relevant mortality and morbidity, a precise indication for its use is indispensable.

La condena será éticamente correcta si la AUU está realmente asociada a tales enfermedades. En la población general se detecta un caso de AUU en cada 320 fetos estudiados ecográficamente. En el 68 % de esas detecciones se tratará de un hallazgo aislado, pero aún así aumenta el riesgo de parto prematuro, de peso bajo y de mortalidad perinatal. Por otra parte, el 17 % de estos fetos tendrán, además de la arteria única, cromosomopatías y el 31 % malformaciones anatómicas. Concluyendo, la AUU es realmente un marcador cardinal de riesgo de trastornos fetales, que debe buscarse activamente durante el seguimiento ecográfico del embarazo.The Spanish Supreme Court has condemned several obstetricians after having informed that the umbilical cord of a fetus had the three vessels, therefore deactivating the search for fetal diseases that the single umbilical artery (SUA would have provoked. The sentence will be ethically correct only if SUA is really associated with such diseases. SUA is found in about 1 out of every 320 fetuses studied sonographically. In 68% of them, it will be an isolated finding, although it will increase the risks of premature delivery, low birthweight, and perinatal mortality. On the other hand, 17% of these fetuses will have, besides SUA, chromosomal alterations, and 31 % of them, structural malformations. In conclusion, SUA is an important marker of fetal disorders, and it has to be actively searched for during the ultrasonographic monitoring of the gestation.

    Full Text Available RAC3 pertenece a la familia de coactivadores de receptores nucleares p160, y se encuentra sobreexpresado en varios tumores. Demostramos previamente que RAC3 es coactivador del factor de transcripción anti-apoptótico NF-kapa;B. En este trabajo investigamos su rol en la apoptosis inducida por H2O2 en una línea celular no tumoral derivada de riñón embrionario humano (HEK293, y por el ligando inductor de apoptosis relacionado a TNF (TRAIL en una línea de leucemia mieloide crónica humana (K562, naturalmente resistente a la muerte por este estímulo. Observamos que las células tumorales K562 poseen niveles altos de RAC3 comparados con las células no tumorales HEK293. La sobreexpresión normal de coactivador o por transfección, inhibe la apoptosis mediante una disminución de la activación de caspasas, translocación del factor inductor de apoptosis (AIF al núcleo, aumento de la actividad de NF-kapa;B y las quinasas AKT y p38 y disminución de la quinasa ERK. Lo opuesto fue observado por disminución de RAC3 mediante la técnica de ARN interferente (RNAi en K562, aumentando así la apoptosis inducida por TRAIL. Estas evidencias sugieren que una sobreexpresión de RAC3 contribuye al desarrollo de tumores, participando en las cascadas que controlan la muerte celular por mecanismos no estrictamente dependientes de hormonas esteroideas y/o de acetilación, constituyendo esto un posible blanco de ataque para el tratamiento de tumores.RAC3 belongs to the family of p160 nuclear receptors coactivators and it is over-expressed in several tumors. We have previously shown that RAC3 is a NF-kappa;B coactivator. In this paper, we investigated the role of RAC3 in cell-sensitivity to apoptosis, using H2O2 in the human embryonic kidney cell line (HEK293, and tumor necrosis factor-related apoptosis inducing ligand (TRAIL in a human chronic myeloid leukemia cell line (K562 naturally resistant to TRAIL. We observed that the tumoral K562 cells have high levels of RAC3 if compared with the non-tumoral HEK293 cells. The normal or transfected coactivator over-expression inhibits apoptosis through a diminished caspase activity and AIF nuclear translocation, increased NF-kappa;B, AKT and p38, and decreased ERK activities. In contrast, inhibition of RAC3 by siRNA induced sensitivity of K562 to TRAIL-induced apoptosis. Such results suggest that over-expression of RAC3 contributes to tumor development through molecular mechanisms that do not depend strictly on acetylation and/or steroid hormones, which control cell death. This could be a possible target for future tumor therapies.

    2016-01-01

    《采菽堂古诗选》是清初诗论家陈祚明评选的先唐古诗选本,其理论核心是情辞的相互关系.陈祚明认为好诗当以情为主、情辞兼备.他所崇尚的“情”是能同化他者的普遍之情、同有之情,且当以含蓄宛转笔法出之.他认为虽人人皆有情,但唯有“心敏”‘笔快”之天才,方能道出同有之情.他着重关注诗歌的语言,主张“择辞而归雅”.其“雅”主要就语言形式而言,与儒家诗教所强调的思想内容无涉.文质之辨、质华之辨,皆归于雅.陈祚明的诗学思想源于刘勰,针对七子派、公安派、竟陵派的弊端采取了折衷调和的策略,目的是使学诗者走上“诗工”之路.

  15. Review of the Parasa undulata (Cai, 1983 species group with the first conifer-feeding larva for Limacodidae and descriptions of two new species from China and Taiwan (Lepidoptera, Limacodidae

    Directory of Open Access Journals (Sweden)

    Shipher Wu

    2013-10-01

    Full Text Available Although the caterpillars are well-known for the stings and magnificent coloration, the systematics of Limacodidae is historically neglected and chaotic due to the difficulty in matching the larval with adult stages as well as the very conservative and convergent adult morphology. One of the biggest taxonomic problems surrounds a collective group from Southeastern Asia, termed the “green limacodid moths”, which harbours at least 90 species placed in the genus Parasa Walker, 1859 and 14 “subunits”. The P. undulata group was previously composed of 3 species from China and Taiwan, and characterized only by wing pattern. This species group is extensively studied herein with two new species described, i.e. P. viridiflamma sp. n. (Taiwan and P. minwangi sp. n. (S. China, and discovery of female genitalia of three species, presenting new phylogenetic insights in this potentially paraphyletic genus. In addition, one limacodid larva was found to be feeding exclusively on Picea (Pinaceae in Taiwan. Its identity, Parasa pygmy Solovyev, 2010 in P. undulata group, is confirmed through matching its COI sequence to the adult. This discovery is also biologically significant because the previous known host breadth of Parasa was of polyphagy on various angiosperm plant families. This case, therefore, represents the first record of conifer-feeding behavior in this family as well as the first of specialized herbivory in the genus. Meanwhile, the background match between Picea leaves and larval coloration is shared with other Picea-feeding insects. This phenomenon is worth of further investigation in the aspect of convergent evolution of crypsis associated with a particular plant.

    In this work an analysis of the influence of the choice of the algorithm or planning system, on the calculus of the same treatment plan is introduced. For this purpose specific software has been developed for comparing plans of a series of IMRT cases of prostate and head and neck cancer calculated using the convolution, superposition and fast superposition algorithms implemented in the XiO 4.40 planning system (CMS). It has also been used for the comparison of the same treatment plan for lung pathology calculated in XiO with the mentioned algorithms, and calculated in the Plan 4.1 planning system (Brainlab) using its pencil beam algorithm. Differences in dose among the treatment plans have been quantified using a set of metrics. The recommendation for the dosimetry of a careful choice of the algorithm has been numerically confirmed.

    Full Text Available AbstractIn this study, the relationship between time-variables of the physical education lesson and fundamental movement skill acquisition and learning was examined. One hundred and ten first grade students and their six physical educators participated. Students were pre-, post-, and re-tested both qualitatively and quantitatively on overhand throwing and catching. The Test of Gross Motor Development (Ulrich, 1985 was used for the assessment of qualitative skill performance and the Michigan Educational Assessment Program (MEAP, 1984 for the assessment of quantitative skill performance. Between pre- and post-tests students received an eight lessons unit instruction with emphasis on overhand throwing and catching. A total number of thirty-six students (6 students X 6 schools were selected, andtheir videotaped motor behavior in the lessons was analyzed with the Academic Learning Time ¿ Physical Education (ALT-PE,Parker, 1989. Regression analysis was applied to calculate students´ residual scores of achievement and to enable further data analysis. Correlation analysis between students´ achievement and ALT-PE categories indicated significant relationships between skill acquisition, learning and ALT-PE categories. It can be concluded that time devoted to practice skills, unlike times pent on activities irrelevant to the instructional task oron games, contributes to skill learning.ResumenEn este trabajo se estudia la relación entre variables temporales de las clases de Educación Física y la adquisición y aprendizaje de habilidades motrices fundamentales. En él participaron ciento diez alumnos de primer grado y seis profesores de Educación Física de Grecia. Los alumnos fueron examinados antes, durante y después tanto en términos cuantitativos como cualitativos en cuanto a lanzamientos y recepciones por encima de la cabeza. Se utilizó el Test de Desarrollo Motor Grueso (Ulrich, 1985 para evaluar el rendimiento en habilidades cualitativas y el Programa de Evaluación Educativa de Michigan (MEAP, 1984 para evaluar el rendimiento en habilidades cuantitativas. Entre las pre y post-pruebas, los alumnos recibieron una unidad formativa de ocho clases con especial énfasis en los lanzamientos y recepciones por encima de la cabeza. Se seleccionó a un total de 36 alumnos (6 alumnos x 6 escuelas y su comportamiento motor, grabado en vídeo durante las clases, fue analizado con el Tiempo de Aprendizaje Académico – Educación Física (ALT-PE, Parker, 1989. Se aplicó un análisis de regresión para calcular las puntuaciones residuales de los alumnos en cuanto a sus logros y permitir el posterior análisis de los datos. El análisis de la correlación entre los logros de los alumnos y las categorías de ALT-PE indicó la existencia de unas importantes relaciones entre la adquisición de habilidades, el aprendizaje y las categorías de ALT-PE. Puede concluirse que el tiempo dedicado al entrenamiento de las habilidades, a diferencia del tiempo dedicado a las habilidades irrelevantes para la tarea formativa o los juegos, contribuye al aprendizaje de habilidades.

Se recomienda, como estrategia asistencial, el encuentro vivido y dialogado, mediado por la escucha, empatía e intersubjetividad, que se desarrolla a partir de la comprensión del modo de ser del humano ante las imposibilidades de la condición serológica y en la búsqueda de desvelar sus posibilidades.The purpose of this phenomenological research is to understand the daily routine of women infected with the virus of human immunodeficiency (HIV prevented from breastfeeding. Twelve women were interviewed in a university hospital in southern Brazil. Their statements, analyzed through a Heideggerian approach, showed that the women reveal themselves as beings-in-the-world and are mainly impersonal. The way of being of de-cadence was unveiled and expressed by occupation, gossip, curiosity, ambiguity, fear, and the inauthenticity of the pact of silence and the unsaid. The helpful care mediated by a dialogic relationship between mother and son/daughter, between the woman and the professional, showed the possibility of movement from inauthenticity to authenticity. We recommend the use of direct and dialogued interaction as an assistance strategy, mediated by listening, empathy and intersubjectivity, and developed through the comprehension of the way of being of the human being in the face of the impossibilities imposed by the serological condition and in their attempt to unveil their possibilities.

    Full Text Available En este trabajo abordamos la problemática de la construcción de subjetividad de trabajadores jóvenes de supermercados desde la perspectiva de su relación con el cliente, ya que consideramos que en ésta se articulan una serie de dimensiones significativas del trabajo en supermercados. Las políticas empresariales en la actualidad tienden a incorporar a la subjetividad obrera en el proceso de valorización del capital y, en este sentido, la atención al cliente se constituye en un mecanismo clave para lograrlo. Además, nos preguntamos cómo se da la apropiación de estos mecanismos por parte de los trabajadores en los procesos de trabajo concretos de atención al cliente, destacando que, si bien estas políticas son eficaces, las prácticas de los trabajadores también conllevan implícitas resignificaciones, apropiaciones y límites frente a estas políticas.In this work we deal with the problem of the subjectivity construction of supermarket´s young workers from the perspective of their relationship with the client, since we consider that in this one a series of significant dimentions of the work in supermarkets are articulated. Nowadays, business politics tend to incorporate workers´ subjectivity in the capital´s appreciation process and, in this sense, attention to customer becomes a key mechanism to achieve it. Besides, we ask ourselves how workers aproppiate this mechanisms in concrete work process of attention to client, emphasizing that, beyond this politics´s effectiveness, workers´ practices also take implicit resignifications, appropiations and limits.

    Full Text Available Après avoir rappelé le contexte de mutation que connaît actuellement le secteur agricole, nous nous interrogeons sur la place du travail dans la fabrication d’une agriculture durable. Dans cette perspective, nous soulignons trois types d’enjeux. Le premier est relatif à l’objectivation des liens travail-santé. En effet, les conditions de travail se dégradent dans le secteur et celui-ci génère de l’exclusion. Et il est loin d’être attractif. Le second renvoie au lien entre conception et travail. L’agriculture actuelle n’est pas soutenable. Et les pratiques productives des agriculteurs sont en pleine mutation. Mais encore faut-il que ces techniques soient actionnables dans le travail. Nous désignons donc trois voies à la prise en compte du travail dans la conception. Le troisième enjeu est relatif au vivre ensemble. Le développement durable pose en effet très profondément la question d’un futur à faire advenir collectivement. Nous considérons alors cette dimension politique comme un « projet », en posant la question de la prise en compte des projets des agriculteurs dans la définition des visées du développement durable.This paper is focused on work in the making of a sustainable agriculture. We emphasize three types of issue. The first one is related to the objectification of occupational health. Agriculture is a tough sector, which produces exclusion and which is far from attractive. The second is related to design. Farming today is not sustainable, and technical systems need to be designed. But the changes need to be actionable at work. So we present three ways needed in order to think out the workers’ activity during the design process. The third issue is related to Policy: sustainable development is also a future to bring together. We suggest that this collective dimension could be grasped as a « project », which takes into consideration the projects of farmers in order to define the aims of sustainable agriculture.Despues de haber recordado el contexto de mutación que conoce actualmente el sector agrícola, nos interrogamos sobre el lugar del trabajo en la construcción de una agricultura sostenible. Dentro de esta perspectiva, subrayamos tres tipos de desafíos. El primero es relativo a la objetivación de los lazos trabajo-salud. En efecto, las condiciones de trabajo se degradan en el sector y este genera exclusión. Lo que esta lejos de ser atractivo. El segundo devuelve al lazo entre concepción y trabajo. La agricultura actual no es sostenible. Y las prácticas productivas de los agricultores estan en plena mutación. Pero es todavía necesario que estas prácticas sean accionables en el trabajo. Designamos tres vías que permiten tomar en cuenta el trabajo en la concepción. El tercer desafío es relativo al vivir juntos. El desarrollo sostenible conlleva profundamente la cuestión de un futuro a construir colectivamente. Consideramos esta dimensión política como un « proyecto », que toma en cuenta los proyectos de los agricultores para definir los objetivos del desarrollo sostenible.

    Full Text Available En el presente trabajo se ha valorado la posible reducción de la tasa de recidivas en la pancreatitis aguda biliar mediante el tratamiento con ácido ursodeoxicólico (AUC entre el episodio de pancreatitis y el momento de la colecistectomía. Se estudiaron 72 primeros episodios consecutivos de pancreatitis aguda biliar, en pacientes no colecistectomizados, seguidos hasta la cirugía. Los casos se dividieron en grupo A (n = 30, tratados al alta con AUC 10 mg/kg/día, hasta la cirugía, y grupo B o control (n = 42. Se evaluaron las diferencias entre ambos grupos en cuanto a características del paciente, gravedad de la pancreatitis, características de la litiasis y demora hasta la cirugía. Analizamos las recidivas de la pancreatitis entre los grupos con y sin AUC. En el grupo con AUC comparamos la duración del tratamiento entre los pacientes con y sin recidiva de la pancreatitis. Los dos grupos no mostraron diferencias significativas en cuanto a ninguno de los parámetros estudiados. Registramos 7/30 (23,3% recidivas en el grupo AUC, frente a 9/42 (21,4% recidivas en el control (p = 0,85. Dentro del grupo AUC, la duración del tratamiento fue similar entre los casos que recidivaron: 4,9±4,5 meses y los no recidivados: 4,4±1,9 meses (p = 0,78. En nuestra experiencia, el empleo de AUC hasta el momento de la colecistectomía no reduce la incidencia de recidiva en los pacientes tras un primer episodio de pancreatitis aguda biliar. La duración del tratamiento con AUC tampoco parece relacionarse con la aparición o no de recidivas.In the present paper, we evaluate the possible reduction in the rate of relapses in acute biliary pancreatitis through treatment with ursodeoxycholic acid (UCA, between the episode of pancreatitis and the moment of cholecystectomy. We studied 72 consecutive first episodes of acute biliary pancreatitis, in patients who had not yet undergone colecistectomy, followed up until surgery. The cases were divided into group A (n=30, treated with ursodeoxycholic acid 10 mg/kg/day, until surgery, and group B or control (n=42. We evaluated the differences between both groups, regarding patient characteristics, pancreatitis severity, characteristics of the lithiasis and delay until surgery. We analysed pancreatitis relapses in both groups, with and without UCA. In the UCA group we compared the duration of treatment between patients with and without pancreatitis relapse. The two groups did not show significant differences regarding any of the studied parameters. We registered 7/30 (23.3% relapses in UCA group, versus 9/42 (21.4% relapses in the control group (p = 0.85. In UCA group, treatment duration was similar between relapsed cases: 4.9±4.5 months and those without relapse: 4.4±1.9 months (p = 0.78. In our experience, the use of UCA until the moment of cholecystectomy does not reduce relapse incidence in patients following the first episode of acute biliary pancreatitis. UCA treatment duration did not seem to be related with the occurrence of pancreatitis relapse.

    Full Text Available Aim: the aim of our study was to evaluate the decrease in viral load (VL that is able to predict antiviral treatment response at one year in patients with chronic hepatitis B. Methods: the clinical records of 66 patients, 31 treated with lamivudine (LAM and 35 treated with adefovir (ADF, were retrospectively reviewed. We measured viral DNA at months 1, 3 and 6. Results: the LAM group showed virological response (VR in 51.6% of patients. Baseline VL was higher in non responders (5.37 ± 1.16 vs. 7.01 ± 1.05; p < 0.001. Responders showed a higher percentage of VL decrease at month 3 from baseline (49.2 vs. 38.3%; p = 0.03. We designed a ROC curve and established a cutoff point for decrease of 30% that had 80% of negative predictive value (NPV. The ADF group showed VR in 57.1% of patients. Baseline VL was higher in nonresponders (4.67 ± 1.22 vs. 5.78 ± 1.34; p = 0.01. We observed a significant decrease in VL (log at months 3 (2.6 ± 1.1 vs. 1.3 ± 1.3; p = 0.03 and 6 (2.6 ± 1.2 vs. 1.3 ± 1.2; p = 0.006. The percentage of decrease of VL from baseline was also statistically significant. We created ROC curves at months 3 and 6, and established the best cutoff points. At month 6 a decrease of 1 log in VL had a NPV of 80%, and a decrease of 20% in VL from baseline had 100% NPV. Conclusion: the decrease in viral DNA at weeks 12 and 24 can predict VR at one year in patients with chronic hepatitis B treated with LAM or ADF. This could optimize treatment.

    Full Text Available Background: sixty percent of patients with irritable bowel disease (IBS are hypersensitive to rectal distension. It is uncertain to what extend the identification of this abnormality has an impact in the clinical outcome. Objective: to evaluate if rectal hypersensitivity is associated with a different clinical outcome, prognosis and use of medical resources. Material and methods: patients with IBS (Rome II criteria who underwent a rectal distension study at least one year before were eligible if they have not been included in any research protocol since then. We reviewed how many times in the last year they came to emergency room, underwent an endoscopy, and consulted a gastroenterologist or other medical physician for any reason. Also, a telephone interview was done by a gastroenterology fellow using a structured questionnaire to evaluate the frequency and severity of their symptoms in the last year and last month. Results: a total of 52 patients were eligible and 38 were included. Forteen were not included because inability to made a phone contact or did not consent to phone interview. Twenty six patients were hypersensitive and 12 normosensitive. Both groups had similar symptoms (frequency and severity but hypersensitive patients visited less to the gastroenterologist (1.2 ± 0.2 vs. 2.9 ± 0.6 times yearly, p Introducción: el 60% de los pacientes con SII tienen hipersensibilidad a la distensión rectal. Se desconoce si la identificación de esta alteración puede modificar su evolución. Objetivo: evaluar si la hipersensibilidad a la distensión rectal se asocia con un diferente pronóstico respecto a la presentación de síntomas y la utilización de recursos sanitarios en pacientes con SII. Material y métodos: se incluyeron pacientes con SII según criterios de Roma II, que habían sido sometidos a un estudio de distensión rectal. Se recogieron datos de los registros informáticos sobre asistencia a consultas especializadas, realización de endoscopias, asistencia a urgencias e ingresos hospitalarios. Además, se realizó entrevista telefónica en la que se interrogó acerca de la existencia de síntomas a lo largo del último año y último mes (características, duración y severidad. Resultados: se evaluaron 38 pacientes, 26 con hipersensibilidad en el estudio de distensión basal y 12 normosensibles. En el momento de la recogida de datos (registro informático y entrevista telefónica el seguimiento medio era de 2,39 años después del estudio de distensión. Los sujetos hipersensibles presentaron una clínica similar a aquellos normosensibles. Se registró una menor tasa de frecuentación anual en las consultas de Aparato Digestivo (1,2 ± 0,2 vs. 2,9 ± 0,6, p < 0,01 por parte de los pacientes hipersensibles sin existir diferencias en el resto de variables estudiadas. Conclusión: la identificación de hipersensibilidad visceral en pacientes con SII conlleva una notable reducción de las consultas al gastroenterólogo, sin que esto pueda explicarse por la mejoría de los síntomas, ni por una menor tendencia a realizar otras consultas médicas.

    Beryllium-10 is a short-lived radionuclide (t{sub 1/2} = 1.4 Myr) uniquely synthesized by spallation reactions and inferred to have been present when the solar system's oldest solids (calcium-aluminum-rich inclusions, CAIs) formed. Yet, the astrophysical site of {sup 10}Be nucleosynthesis is uncertain. We report Li-Be-B isotope measurements of CAIs from CV chondrites, including CAIs that formed with the canonical {sup 26}Al/{sup 27}Al ratio of {approx}5 Multiplication-Sign 10{sup -5} (canonical CAIs) and CAIs with Fractionation and Unidentified Nuclear isotope effects (FUN-CAIs) characterized by {sup 26}Al/{sup 27}Al ratios much lower than the canonical value. Our measurements demonstrate the presence of four distinct fossil {sup 10}Be/{sup 9}Be isochrons, lower in the FUN-CAIs than in the canonical CAIs, and variable within these classes. Given that FUN-CAI precursors escaped evaporation-recondensation prior to evaporative melting, we suggest that the {sup 10}Be/{sup 9}Be ratio recorded by FUN-CAIs represents a baseline level present in presolar material inherited from the protosolar molecular cloud, generated via enhanced trapping of galactic cosmic rays. The higher and possibly variable apparent {sup 10}Be/{sup 9}Be ratios of canonical CAIs reflect additional spallogenesis, either in the gaseous CAI-forming reservoir, or in the inclusions themselves: this indicates at least two nucleosynthetic sources of {sup 10}Be in the early solar system. The most promising locale for {sup 10}Be synthesis is close to the proto-Sun during its early mass-accreting stages, as these are thought to coincide with periods of intense particle irradiation occurring on timescales significantly shorter than the formation interval of canonical CAIs.

    Whereas it is generally accepted that calcium-aluminum-rich inclusions (CAIs) from chondritic meteorites formed in a hot environment in the solar protoplanetary disk, the conditions of their formation remain debated. Recent laboratory studies of CAIs have provided new kind of data: their size distributions. We show that size distributions of CAIs measured in laboratory from sections of carbonaceous chondrites have a power law size distribution with cumulative size exponent between -1.7 and -1.9, which translates into cumulative size exponent between -2.5 and -2.8 after correction for sectioning. To explain these observations, numerical simulations were run to explore the growth of CAIs from micrometer to centimeter sizes, in a hot and turbulent protoplanetary disk through the competition of coagulation and fragmentation. We show that the size distributions obtained in growth simulations are in agreement with CAIs size distributions in meteorites. We explain the CAI sharp cut-off of their size distribution at ...

    Central adrenal insufficiency (CAI) in acromegaly may be related to pituitary adenoma or induced by various medical treatments, transsphenoidal neurosurgery (TNS) or radiotherapy (RT), alone or combined. We assessed the role of all available treatments for acromegaly in inducing CAI. We retrospectively studied 97 patients. CAI was diagnosed if morning serum cortisol was <138 nmol/l, or if its response was inadequate in the low-dose short synacthen test. Seventy-four subjects underwent TNS (and 17 of whom also underwent RT), and 23 were on primary medical therapy: overall we diagnosed 21 cases of CAI. Duration of acromegaly, invasion of cavernous sinus, disease control, and type of medical treatment were much the same for patients with and without CAI, which was identified in 18% of patients (10/57) after one TNS, and in 53% (9/17) after RT (p=0.01); repeat surgery increased the risk of CAI (p=0.02). The risk of CAI onset during the follow-up was lower among patients treated with TNS or medical therapy than after RT (p=0.035). Medical treatment did not raise the risk of CAI, whereas a 5- and 4-fold higher risk of CAI was associated with repeat TNS and RT, respectively. Basal or stimulated cortisol levels were similar among acromegalic patients without CAI and matched controls with nonsecreting pituitary lesions. A significant proportion of patients with acromegaly developed CAI over time. While primary or secondary medical treatment did not contribute to the risk of CAI, repeat TNS and RT correlated with pituitary-adrenal axis impairment.

    Objective To compare the ultrastructural changes in hippocampal CA1 during morphine induced conditioned place preference establishment and extinction in rats, and to elucidate the relation between the ultrastructural changes and the progress of conditioned place preference. Methods Morphine was administered via subcutaneous injection at constant dose (10 mg/kg) for 8 d to establish morphine CPP. The rats were given 10 d saline extinction training to extinguish CPP. The changes of ultrastructures in hippocampus during morphine induced conditioned place preference establishment and extinction in rats were observed dynamically by using transimission electron microscope. Results Injecting morphine (10 mg/kg) for 8 d succeeded to produce CPP. After 10 days training with saline, CPP failed to be induced. Ultrastructure of CPP establishment displayed degeneration and necrosis mainly, such as endochylema swelling, rough endoplasmic reticulum (RER)extension, mitochondria swelling and solution, cell pyknosis and so on. Ultra.structure of CPP extinction reflected necrosis and apoptosis mainly, such as karyopyknosis, endechylema swelling and electro-dense raised up,organelle and cell membrane solution, endoplasmie reticulum cisterua formation, karyon euchromatin thickening and margination, perinuclear cistema augmentation and so on. Concltusion The inreversible damage have taken place in hippovampal CA1 neurons, and this change may be related to morphine psychological dependence.%目的 比较吗啡(morphine,mor)诱导的条件性位置偏爱(conditioned place preference,CPP)建立和消退阶段大鼠海马CA1区超微结构的变化,揭示海马CA1区超微结构的变化与CPP建立和消退过程的关系.方法 恒量法(10 mg/kg)连续颈背部皮下注射(subcutaneous,SC)吗啡8 d建立吗啡依赖大鼠CPP模型;用生理盐水替代吗啡训练大鼠10 d,使形成的CPP逐渐消退.应用透射电镜动态观测吗啡CPP建立和消退大鼠海马CA1区超微结构的变化.结果 10 mg/kg吗啡8 d诱导CPP建立,生理盐水训练10 d可以成功消退CPP;CPP建立阶段海马CA1区超微结构以变性和坏死为主,主要表现为胞浆肿胀,粗面内质网扩张,线粒体肿胀、溶解,细胞固缩等;消退阶段超微结构以坏死和凋亡为主,主要表现为细胞核固缩、胞浆肿胀、电子致密度增高,细胞器、细胞膜溶解,内质网池形成,细胞核常染色质浓聚、边集,核周隙增大等.结论 海马CA1区神经元发生不可逆的损害,此变化可能与吗啡精神依赖有关.

Com tal proposta, visamos identificar as transformações ocorridas no cotidiano desses obreiros, principalmente dos militantes, evidenciando a relação entre o dia a dia dessa classe trabalhadora e sua atividade sindical, bem como o caráter de identificação do “ser estivador”, no período acima mencionado. Será a partir do estudo da memória reavivada dos nossos protagonistas e do dialogo com as demais fontes, que buscaremos compreender os indícios de autonomia e as formas de resistência à dominação a que foi submetido o Sindicato da Estiva de Rio Grande durante o final do regime populista-trabalhista e nos primeiros anos da historicamente, ditadura civil - militar de 1964. Por fim, ao analisar o cotidiano dos estivadores desta cidade, através das fontes e do aporte teórico, entenderemos os aspectos simbólicos que perpassam o “ser estivador” dentro de um rol de categorias de trabalho portuário, bem como a imagem e a representatividade desses obreiros na sociedade Rio-grandina

    Objective To understand mental health status and related factors among children and adolescents in Zhongshan,and provide scientific basis for the promotion of their mental health. Methods A total of 2281 students in four primary and secondary schools of Zhongshan City were sampled by stratified random cluster sampling. They were investigated with Achenbach Children Behav-ior Scale(CBCL),Parents’Rearing Style Questionnaire(EMBU)and General situation questionnaire for children and adolescents. Results Among the 2281 students,the prevalence of behavioral problems was 18. 76% ,and there was no significant difference be-tween male and female students(P 0.05)。非父母抚养组及低收入组外化性行为得分分别高于父母抚养组及中高收入组[(7.08±6.41)vs.(6.12±7.10);(6.63±6.72)vs.(5.93±7.59),P 均<0.05],非家庭和睦组在内化性行为得分、外化性行为得分及行为问题总分上都高于家庭和睦组( P 均<0.01)。Pearson 相关分析显示,儿童青少年内化性行为得分、外化性行为得分及行为问题总分均与父、母的温暖理解因子得分呈负相关(r =-0.18~-0.13,P 均<0.01),与父母的惩罚严厉、拒绝否认、过度保护干涉等因子得分呈正相关(r =0.11~0.24,P 均<0.01)。进一步 logistic 回归分析显示儿童青少年行为问题相关因素依次是:家庭氛围、父亲温暖理解、母亲过度保护及干涉(P 均<0.05)。其中,家庭氛围越紧张,父亲温暖理解得分越低,母亲过度保护及干涉得分越高,儿童青少年越倾向于出现行为障碍(P 均<0.05)。结论中山市儿童青少年行为问题较突出,紧张的家庭氛围、母亲过度保护干涉及缺乏父亲温暖理解的教养方式对行为问题的发生有不利影响。

    钟理和缺席日据时代台湾皇民化阶段,是一颗遗落的“左翼”种子,崇尚“赛先生”和“德先生”,与主持《联合报》副刊的林海音等人有暗合之处,其塑造的平妹形象为台湾文坛吹进了一股清新的风;《笠山农场》热情地歌颂年轻人对封建习俗的反抗斗争精神。后半生的钟理和却为民俗所包围,陷入了人间炼狱。返台初期的作品依然保持着强烈的社会批判精神,但1954年次子立民夭折对他产生巨大的精神打击。此后的作品依然带有微讽的意味,斗志却逐渐被消磨,民俗书写越来越凸显。%Chung Li-ho, absent from the kōminka period of Taiwan in the Japanese occupation era, was a lost‘leftwing’ seed, who worshipped‘Mr Science’and‘Mr Democracy’and whose ideas happened to accord with those of such people as Lin Haiyin, affiliated with the literary supplement of The United Daily News. The image of Ping Mei(or Younger Sister Ping), one of his fictional protagonists, brought a new breath of breeze into the world of letters in Taiwan, and his Lishan Nongchang (The Farm at Lishan Mountain), passionately sings of the spirit of the young in their fight against the feudalistic customs. In the latter part of his life, however, Chung Li-ho, surrounded by the folk customs, was plunged into a hell on earth. Although his work in the early days of his return to Taiwan retained its spirit of strong social critique, but the death of his second son, Li-min, in 1954, came as a great spiritual blow to him. Even though his subsequent work remained slightly ironic, his fighting spirit had worn down and his writing became sharply oriented towards the folk customs.

    Full Text Available Background. Late transient neonatal hypocalcemia with hyperphosphatemia is potentially life-threatening. The use of dihydroxycholecalciferol in the management of neonatal hypocalcemia is unexplored. Objective. We hypothesized adding dihydroxycholecalciferol to intravenous continuous calcium infusion (CaI will achieve accelerated correction of hypocalcemia. Design/Methods. A controlled double-blind randomized placebo group was organized to compare the addition of dihydroxycholecalciferol to CaI in 3–14 day old neonates presenting with hypocalcemia, hyperphosphatemia and seizures. Ionized calcium and phosphorus were measured to adjust CaI and maintain eucalcemia. Time to resolution of hypocalcemia was defined as time from starting CaI to the first ionized calcium of  mmol/L. CaI was discontinued when ionized calcium levels were  mmol/L on two measurements and the infant tolerated feeds. Results. Fourteen neonates were studied without statistical difference between groups. Time to correction of hypocalcemia for 1,25 dihydroxycholecalciferol versus placebo was versus hours respectively (. The duration of CaI was versus hours respectively (. Conclusions. The addition of dihydroxycholecalciferol to standard CaI therapy reduced the duration of CaI, but did not reduce the time to correct hypocalcemia in neonates with late transient hypocalcemia.
