    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.

    Calcium, Aluminum-rich inclusions (CAIs) are the first forming solids of the Solar system. Their observed abundance, mean size, and mineralogy vary quite significantly between different groups of chondrites. These differences may reflect the dynamics and distinct cosmochemical conditions present in the region(s) of the protoplanetary disk from which each type likely accreted. Only about 11 such objects have been found in L and LL type while another 57 have been found in H type ordinary chondrites, compared to thousands in carbonaceous chondrites. At issue is whether the rare CAIs contained in ordinary chondrites truly reflect a distinct population from the inclusions commonly found in other chondrite types. Semarkona (LL3.00) (fall, 691 g) is the most pristine chondrite available in our meteorite collection. Here we report petrography and mineralogy of 3 CAIs from Semarkona

    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.

    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

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

    Energy Technology Data Exchange (ETDEWEB)

    2009-06-18

    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

    The authors analyze climatic hydrologic data from 110 sites collected from the middle of the twentieth century to the present in the Tien Shan, one of the largest mountain systems of central Asia. In spite of a few confounding interregional variations in the temporal changes of surface air temperature, precipitation, runoff, glacier mass, and snow thickness in the Tien Shan, it has been possible to establish statistically significant long-range, with slightly lower values below 2000-m elevation. The precipitation in the Tien Shan increased 1.2 mm yr{sup -1} over the past half-century. The precipitation increase is larger at low altitudes in the northern and western regions than at altitudes above 2000 m. A decrease in snow resources occurred almost everywhere in the Tien Shan; the maximum snow thickness an snow duration have decreased on average 10 cm and 9 days, respectively. The annual runoff is the type of precipitation (liquid or solid). Over the last few decades, periods of glacier decline have coincided with declining river runoff. 45 refs., 8 figs., 2 tabs.

  15. 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.

  18. The Vibrio cholerae quorum-sensing autoinducer CAI-1: analysis of the biosynthetic enzyme CqsA

    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.

    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

    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.

  8. The Anatomy and Bulk Composition of CAI Rims in the Vigarano (CV3) Chondrite

    Science.gov (United States)

    Ruzicka, A.; Boynton, W. V.

    1993-07-01

    A striking feature of Ca,Al-rich inclusions (CAIs) in chondrites is the presence of mineralogical layers that typically form rim sequences up to 50 micrometers thick [1]. Many ideas regarding the origin of CAI rims have been proposed, but none are entirely satisfactory. The detailed mineralogy and bulk compositions of relatively unaltered CAI rims in the Vigarano (CV3) chondrite described here provide constraints on hypotheses of rim formation. Rim Mineralogy: CAIs in Vigarano consist of melilite (mel)- and spinel (sp)- rich varieties, both of which are rimmed [2]. Around mel-rich objects, the layer sequence is CAI interior --> sp-rich layer (sometimes absent) --> mel/anorthite (anor) layer --> Ti-Al-rich clinopyroxene (Tpx) layer --> Al- diopside (Al-diop) layer --> olivine (ol) +/- Al-diop layer --> host matrix. The sequence around sp-rich objects differs from this in that the mel/anor layer is absent. Both the sp-rich layer around mel-cored CAIs and the cores of sp-rich CAIs in Vigarano are largely comprised of a fine-grained (anor layer is sometimes monomineralic, consisting of mel alone, or bimineralic, consisting of both mel and anor. Where bimineralic, anor typically occurs in the outer part of the layer. In places, anor (An(sub)99-100) has partially altered to nepheline and voids. Rim mel is systematically less gehlenitic than mel in the CAI interiors, especially compared to mel in the interior adjacent to the rims. The Tpx layer (>2 and up to 15 wt% TiO2) and Al-diop layer ( sp + fo --> sp + fo + anor or mel or Tpx) that does not correspond to observed rim sequences. It thus appears that (1) the rim region did not form through crystallization of molten CAIs; and (2) rim layers did not originate solely by the crystallization of a melt layer present on a solid CAI core [4,5].

    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.

    Full Text Available Thermal patterns of an area which underwent a polyphase deformation history such as the Carnic Alps were analyzed using the Colour Alteration Index (CAI of conodonts in order to constrain some aspects of the metamorphic history of this part of the Southern Alps. Hercynian and alpine tectonothermal events were distinguished using CAI analysis.  The Hercynian event developed temperatures up to low metamorphic conditions. Alpine tectonogenesis did not produce thermal levels in excess of the diagenetic zone. Moreover, CAI patterns allow recognition and evaluation of a hydrothermal metamorphic overprint of Permo-Triassic or Oligocene age that was superimposed on the pre-existing regional metamorphic zonation.

    Quorum sensing is a mechanism of chemical communication among bacteria that enables collective behaviors. In V. cholerae, the etiological agent of the disease cholera, quorum sensing controls group behaviors including virulence factor production and biofilm formation. The major V. cholerae quorum-sensing system consists of the extracellular signal molecule called CAI-1 and its cognate membrane bound receptor called CqsS. Here, the ligand binding activity of CqsS is probed with structural analogs of the natural signal. Enabled by our discovery of a structurally simplified analog of CAI-1, we prepared and analyzed a focused library. The molecules were designed to probe the effects of conformational and structural changes along the length of the fatty acid tail of CAI-1. Our results, combined with pharmacophore modeling, suggest a molecular basis for signal molecule recognition and receptor fidelity with respect to the fatty acid tail portion of CAI-1. These efforts provide novel probes to enhance discovery of anti-virulence agents for the treatment of V. cholerae. PMID:23092313

    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.

  9. Limited subsolidus diffusion in type B1 CAI: Evidence from Ti distribution in spinel

    Science.gov (United States)

    Meeker, G. P.; Quick, J. E.; Paque, Julie M.

    1993-01-01

    Most models of calcium aluminum-rich inclusions (CAI) have focused on early stages of formation by equilibrium crystallization of a homogeneous liquid. Less is known about the subsolidus cooling history of CAI. Chemical and isotopic heterogeneties on a scale of tens to hundreds of micrometers (e.g. MacPherson et al. (1989) and Podosek, et al. (1991)) suggest fairly rapid cooling with a minimum of subsolidus diffusion. However, transmission electron microscopy indicates that solid state diffusion may have been an important process at a smaller scale (Barber et al. 1984). If so, chemical evidence for diffusion could provide constraints on cooling times and temperatures. With this in mind, we have begun an investigation of the Ti distribution in spinels from two type B1 CAI from Allende to determine if post-crystallization diffusion was a significant process. The type B1 CAIs, 3529Z and 5241 have been described by Podosek et al. (1991) and by El Goresy et al. (1985) and MacPherson et al. (1989). We have analyzed spinels in these inclusions using the electron microprobe. These spinels are generally euhedral, range in size from less than 10 to 15 micron and are poikilitically enclosed by millimeter-sized pyroxene, melilite, and anorthite. Analyses were obtained from both the mantles and cores of the inclusions. Compositions of pyroxene in the vicinity of individual spinel grains were obtained by analyzing at least two points on opposite sides of the spinel and averaging the compositions. The pyroxene analyses were obtained within 15 microns of the spinel-pyroxene interface. No compositional gradients were observed within single spinel crystals. Ti concentrations in spinels included within pyroxene, melilite, and anorthite are presented.

  10. Recent glacier changes in the Tien Shan observed by satellite gravity measurements

    Jin, Shuanggen; Tian, X.; Feng, G.

    2016-08-01

    The glaciers in the Tien Shan are extensive and play an important role in water cycle in central Asia. However, it is difficult to accurately monitor glacier variations in the Tien Shan due to the lack of in situ widespread measurements. In this paper, glacier mass variations in the Tian Shan are obtained and investigated from 10 years of monthly GRACE gravity solutions (January 2003-December 2012) and the WaterGAP Global Hydrology Model (WGHM), including seasonal, secular and interannual variations . Results show that significant seasonal variations of glacier mass are found with the maximum normally in April-June and the minimum around in November-December. The trends in all four regions are positive from 2002 to 2005 and negative from 2005 to 2012, indicating that the Tien Shan glaciers are increasing prior to 2005 and significantly melting after 2005. These changes are consistent with the temperature change in the Tien Shan. In addition, in the past decade the precipitation has decreased and evapotranspiration has increased, which have joint influences on glacier mass changes in different regions of the Tien Shan.

  11. Numerical investigation of CAI Combustion in the Opposed- Piston Engine with Direct and Indirect Water Injection

    Science.gov (United States)

    Pyszczek, R.; Mazuro, P.; Teodorczyk, A.

    2016-09-01

    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.

  17. Density Structure, Isostatic Balance and Tectonic Models of the Central Tien Shan

    Science.gov (United States)

    Kaban, Mikhail K.; Yuanda, T. Reiza

    2014-11-01

    A new combined satellite-terrestrial model of the gravity field is used together with seismic data for construction of a density model of the lithosphere of the Central Tien Shan and for estimation of its isostatic balance. The Tien Shan is one of the most active intraplate orogens in the world, located about 1,500 km north of the convergence between Indian and Eurasian plate, and surrounded by stable Kazakh platform to the north and the Tarim block to the south. Although this area was extensively studied during recent decades, several principal problems, related to its structure and tectonics, remain unsolved up to now: (1) various geodynamic scenarios have been discussed so far to explain tectonic evolution, such as direct "crustal shortening," intracontinental subduction and some others, but no definite evidence for any of them has been found. (2) Still, it is not clear why Tien Shan grows so far from the plate boundary at the Himalayan collision zone. Gravity modeling can provide valuable constraints to resolve these questions. The results of this study show that: (1) there exists a very strong deflection of the Tien Shan lithosphere from isostatic equilibrium. At the same time, the patterns of the isostatic anomalies are very different in the Western and Central Tien Shan. The latter one is characterized by much stronger variations. The best fit of the modeling results is found for the model according to which the Tarim plate partially underthrusts the Central Tien Shan; (2) negative density anomalies in the upper mantle under the central block possibly relate to magmatic underplating during the initial stage of the tectonic evolution. Therefore, the weak lithosphere could be the factor that initiates mountain building far away from the collision zone. Alternatively, this might be a gap after detachment of the eclogised lower crust and lithospheric lid, which is filled with the hot asthenospheric material.

    2007-10-15

    In this study, we estimated the current glacier state and forecast the potential impact of global and regional climate change on the glaciers and glacier runoff in the Tien Shan. General (G) and detailed (D) simulations were developed based on assessment of the Tien Shan glacier recession between 1943 and 2003 using an iterative stepwise increase in the equilibrium line altitude of 20 m. The G simulation was developed for 2777 grids each of which covered over 1000 km{sup 2} of glacier surface and D for the 15 953 Tien Shan glaciers. Both simulations employed glacier morphometric characteristics derived from Digital Elevation Model based on remote sensing data, high resolution maps and in situ GPS validation. Simulated changes in glacier area demonstrated that a possible increase in air temperature of 1 deg. C at E-barLA must be compensated by a 100 mm increase in precipitation at the same altitude if Tien Shan glaciers are to be maintained in their current state. An increase in mean air temperature of 4 deg. C and precipitation of 1.1 times the current level could increase E-barLA by 570 m during the 21st century. Under these conditions, the number of glaciers, glacier covered area, glacier volume, and glacier runoff are predicted to be 94%, 69%, 75%, and 75% of current values. The maximum glacier runoff may reach as much as 1.25 times current levels while the minimum will likely equal zero.

  19. Characterization of Meteorites by Focused Ion Beam Sectioning: Recent Applications to CAIs and Primitive Meteorite Matrices

    2015-01-01

    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 Human immunodeficiency virus 1 derived capsid assembly inhibitor peptide (HIV-1 CAI-peptide) is a promising lead candidate for anti-HIV drug development. Its drawback, however, is that it cannot permeate cells directly. Here we report the transport of the pharmacologically active CAI-peptide into human lymphocytes and Human Embryonic Lung cells (HEL) using the BioShuttle platform. Generally, the transfer of pharmacologically active substances across membranes, demonstrated by confocal laser scanning microscopy (CLSM), could lead to a loss of function by changing the molecule's structure. Molecular dynamics (MD) simulations and circular dichroism (CD) studies suggest that the CAI-peptide has an intrinsic capacity to form a helical structure, which seems to be critical for the pharmacological effect as revealed by intensive docking calculations and comparison with control peptides.

    Full Text Available One important question concerning the sustainability of local or native populations refers to their interaction with local and global institutions. We should expect that populations with capacity to interact economically and politically with institutions, might show a better chance for their ecological and cultural continuity, as well as for their system of trade and subsistence. The level of ecological and social interaction of local populations, following concepts from ecology, occurs on different scales: for example, from the territories of individual fishermen on the Atlantic Forest coast to organizations of community Extractive Reserves in the Amazon. The scale of organization (individual/family/community may influence the capacity to deal with institutions. This study analyses how Brazilian native populations, especially caiçaras of the Atlantic Forest coast, and caboclos from the Amazon, have interacted with regional, national and global institutions, concerning environmental demands. Concepts such as common management, natural capital, resilience and sustainability are useful to understand these illustrative cases.Uma questão importante da sustentabilidade de populações locais ou nativas se refere à interação com as instituições locais e globais. Podemos esperar que populações que demonstrem capacidade de interagir de forma econômica e política com as instituições apresentem também uma chance maior de continuidade cultural e ecológica, assim como de seus sistemas de troca e subsistência.

    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

    CAI Jing was appointed the prime minister in the Chongning period of Song Hui-tsung. The Medical School was moved to the Imperial College from Taichang Temple. It used a 3-year education system and divided graduates into three grades. The preferential policies promised top students as 8 or 9-rank official position, which attracted a lot of intellectuals into the field of medicine. CAI Jing was demoted three times respectively in the fifth year of the Chongning period, the third year of the Daguan period and the second year of the Zhenghe period, and was promoted again after each demotion. Influenced by changes of CAI Jing's position and relative policies, the Medical School was also established and abolished three times. PMID:21624269

    Variations in refractory major and trace element composition of calcium, aluminum-rich inclusions (CAIs) provide constraints on physical and chemical conditions and processes in the earliest stages of the Solar System. Previous work indicates that CAIs have experienced complex histories involving, in many cases, multiple episodes of condensation, evaporation, and partial melting. We have analyzed major and trace element abundances in two core to rim transects of the melilite mantle as well as interior major phases of a Type B1 CAI (EK-459-5-1) from Allende by electron probe micro-analyzer (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to investigate the behavior of key trace elements with a primary focus on the REEs Tm and Yb.

    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 a...

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

    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.

  13. Cosmic rays and thunderstorms at the Tien-Shan mountain station

    International Nuclear Information System (INIS)

    Experimental work of the past few years has shown that runaway breakdown determines the maximum electric field strength in thunderclouds and is behind a variety of phenomena newly observed in thunderstorm atmosphere, such as TGFs, TLEs, etc. The necessary condition for the occurrence of runaway avalanche is the existence of high-energy electrons. In the atmosphere, these are the cosmic ray secondary electrons. Therefore the observed effects reflect close relationship between cosmic rays and electrodynamic processes in a thunderstorm atmosphere. The Tien-Shan high-altitude cosmic ray station is a unique site for investigations effects of cosmic rays and thunderstorm discharge. 'Thunderstorm' detector complex is designed especially for a systematical study of atmospheric discharges by the means of simultaneous recording of the different kinds of radiation. The presence of a widespread extensive air shower trigger set-up at the Tien-Shan station permits to study the role of energetic cosmic ray particles in lightning development. Overview of main results, obtain during last several years at the Tien-Shan are presented. A phenomenological description and theoretical vision of the cosmic rays role in atmosphere processes during thunderstorm are discussed.

    The chemical and isotopic compositions of calcium-aluminum-rich inclusions (CAIs) can be used to understand the conditions present in the protoplantary disk where they formed. The isotopic compositions of these early-formed nebular materials are largely controlled by chemical volatility. The isotopic effects of evaporation/sublimation, which are well explained by both theory and experimental work, lead to enrichments of the heavy isotopes that are often exhibited by the moderately refractory elements Mg and Si. Less well understood are the isotopic effects of condensation, which limits our ability to determine whether a CAI is a primary condensate and/or retains any evidence of its primordial formation history.

  15. Temporal and Spatial Changes of Permafrost in the Tien Shan Mountains Since the Little Ice Age.

    2006-12-01

    During the Late Holocene there were numerous periods of warming and cooling in the Tien Shan Mountains, Central Asia. Ground temperatures and permafrost area in the Tien Shan have been subjected to repeated fluctuations during the last millennia brought about by the general planetary changes in climate. The altitudinal oscillations of the mean annual air temperature (MAAT) zero Centigrade isotherm had a range of about 300 m during that time. Air temperature in the Tien Shan Mountains has increased at a higher rate than the global mean during the 20th century. Climate warming in the high-mountains regions could induce the further near-surface permafrost degradation, which may lead to slope instability and permafrost-related hazards. The main objectives of the modeling process were to estimate the permafrost thermal regime and assess the area where permafrost disappeared since the second part of the nineteenth century. To estimate the effect of climate change on permafrost a one-dimensional process-based model was used to simulate the ground thermal regime of the Tien Shan at a resolution of a half-degree latitude-longitude since the Little Ice Age up to present. The results of numerical simulation show that at an altitude of 2500 m a.s.l. the permafrost temporary formed at least three times during the last 500 years. At the lover altitudinal boundary of permafrost distribution the permafrost temperatures now are close to 0°C and at some sites permafrost degradation has already started. Analysis of measured active layer and permafrost temperatures coupled with numerical thermal modeling (permafrost temperature reanalysis) shows that most of the recently thawed permafrost was formed during the Little Ice Age. The modeling of alpine permafrost dynamics shows that the altitudinal lower boundary of permafrost distribution has shifted by about 150-200 m upward since the end of the Little Ice Age (circa 1850). During the same period, the area of permafrost distribution

    Snow melt in the Tien Shan region accounts for a large portion of the seasonal water supply for millions of inhabitants of central Asia. Studies based on in situ records suggest that maximum snow depth and snow duration in the Tien Shan has decreased, as has annual river flow at lower elevations, over the past 50 years [Aizen et al., 1997]. While the need to monitor trends in winter snow accumulation increase as this resource is threatened by climate change, the number of in situ measurements of snow depth has declined, forcing reliance on remote sensing methods. This talk will describe trends in seasonal snow cover for 8 individual hydrological basins in Central Asia, as well as for the Tien Shan as a whole, using operational products derived from the MODIS Terra instrument. The ultimate goal is to provide input data for snow runoff models. Data from the Moderate-Resolution Imaging Spectroradiometer (MODIS) data, available since early 2000, have proven useful for a large variety of land, ocean and atmospheric applications. The MODIS standard snow-cover products, archived at the National Snow and Ice Data Center, are available in swath-based, daily, 8-day and monthly aggregations at a variety of spatial resolutions and grids. Similar products are also available from the MODIS Aqua instrument launched in 2002. For this study daily and 8-day products at 500m resolution were used. Seven winter seasons were analyzed. For a given season the date of maximum snow coverage varies widely between basins but for the Tien Shan as a whole the period of peak coverage and the rate at which the total snow covered area declines is rather consistent for the 7 winters. Some basins have a large degree of the interannual variability in maximum snow cover while for others this variability is small. Interannual variability in total snow cover for the Tien Shan as a whole is approximately 10 % RMS throughout the peak and decay periods, with 2003 having the most snow cover and 2000 having

    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

    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. PMID:26832141

    Full Text Available Abstract Background The Brazilian Atlantic Forest is considered one of the hotspots for conservation, comprising remnants of rain forest along the eastern Brazilian coast. Its native inhabitants in the Southeastern coast include the Caiçaras (descendants from Amerindians and European colonizers, with a deep knowledge on the natural resources used for their livelihood. Methods We studied the use of the terrestrial fauna in three Caiçara communities, through open-ended interviews with 116 native residents. Data were checked through systematic observations and collection of zoological material. Results The dependence on the terrestrial fauna by Caiçaras is especially for food and medicine. The main species used are Didelphis spp., Dasyprocta azarae, Dasypus novemcinctus, and small birds (several species of Turdidae. Contrasting with a high dependency on terrestrial fauna resources by native Amazonians, the Caiçaras do not show a constant dependency on these resources. Nevertheless, the occasional hunting of native animals represents a complimentary source of animal protein. Conclusion Indigenous or local knowledge on native resources is important in order to promote local development in a sustainable way, and can help to conserve biodiversity, particularly if the resource is sporadically used and not commercially exploited.

    With a growing interest in learning Chinese globally, there is a growing interest for phonologists and language instructors to understand how nonnative Chinese learners perceive the Chinese sound inventory. We experimentally investigated the Danish (L 1) speaker’s perception of three Mandarin...... results show that beginner learners perform on chance level regarding the distinction between t and z and between c and z. The reason is that in Danish, which has an aspiration contrast between plosives (like Chinese) /th/ is variably pronounced as affricated /ts/ and many speakers are unaware of this...... optional variation. This inhibits the distinction between Chinese t and z (pronounced as /th ts/). Further, Danish has no affricates, which makes the distinction between different affricates based on the aspiration contrast (like cai-zai) particularly difficult....

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

    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.

  4. Climate- vs. Earthquake-induced Rock-Glacier Advances in the Tien Shan: Insights from Lichenometry

    2014-05-01

    Rock glaciers have been traditionally used as landform proxies of the distribution of sporadic alpine permafrost. In the northern Tien Shan mountains of Kyrgyzstan, most distinct lobes of >200 rock glaciers that we mapped from satellite imagery occur at two major elevation levels. However, a number of particularly low-lying lobes seem difficult to reconcile with palaeoclimatic fluctuations and commensurate changes of permafrost patterns: The minimum elevation of the majority of rock-glacier snouts lies between ~2500 up to ~3700 m a.s.l., but some 10% of rock-glaciers extend down to well below 3000 m a.s.l. We hypothesize that some of the rock glaciers in this area may have formed following strong earthquakes that could have triggered massive supraglacial rock-slope failures, which would have subsequently created sediment-rich rock glaciers from clear-ice glaciers. Our hypothesis is based on the observation that the tectonically active northern Tien Shan of Kyrgyzstan and Kazakhstan was affected by a series of major earthquakes in the late 19th and earliest 20th centuries, e.g. in 1885 (Ms 6.9), 1887 (Ms 7.3), 1889 (Ms 8.3), and 1911 (Ms 8.1). All of these earthquakes had triggered numerous landslides in the northern Tien Shan. It is also likely that similarly strong earthquakes had happened before, but their recurrence intervals are long and more palaeoseismological work is in progress. We test whether lichenometry of rock-glacier surfaces together with morphometric analysis are suitable methods to testing our hypothesis. We focus on assessing the possibility of earthquake-triggered rock-glacier advances, and use lichenometry to resolve age patterns of different rock-glacier lobes. We use a dataset of several thousand lichen diameter measurements encompassing seven different species calibrated by gravestones and dated mass-movement deposits. Data on four single and two merging rock glaciers in four selected valleys in Kyrgyzstan and Kazakhstan support the notion

  5. 2.5d teleseismic waveform tomography with application to the tien shan

    Science.gov (United States)

    Baker, Benjamin Ian

    The analysis of passive source seismic data recorded by quasi-linear deployments of broadband stations at teleseismic distances has proven to be an effective means of probing the subsurface of the Earth. However, current methodologies are far from being able to exploit all the interpretable signal in these data sets. In this thesis, I describe a 2.5D, frequency domain, visco-elastic waveform tomography algorithm for imaging with this type of data. To compute synthetic seismograms (the forward problem), the general equations of motion are discretized with p-adaptive finite elements. This approach allows for geometric flexibility and accurate solutions as a function of wavelength. Artificial force distributions manifesting Huygen's principle for the teleseismic events are introduced locally through a Bielak layer. Because of the relatively low frequency content of teleseismic data, regional scale tectonic settings can be parameterized with a modest number of variables and perturbations can be determined directly from a regularized Gauss-Newton system of equations. Waveforms generated by the forward problem compare well with analytic solutions for simple 1D media and with those generated in heterogeneous structures by a finite difference technique. It is demonstrated through examples that the regularized approximate Hessian is particularly effective at focusing backpropagated residuals to their true location. It is observed that full waveform inversion can provide significantly better vertical resolution than arrival time tomography and significantly better lateral resolution than standard surface wave tomography. Used in tandem in a multi-scale approach, surface wave tomography followed by joint surface wave/body wave tomography is shown to be an effective strategy for image reconstruction from a simple starting model. This inversion strategy is then applied to body and surface wave teleseismic waves recorded in the Tien Shan. The work of previous investigators is

    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.

    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

    The observed increase in summer temperatures and the related glacier downwasting has led to a noticeable decrease of frozen water resources in Central Asia, with possible future impacts on the economy of all downstream countries in the region. Glaciers in the Ak-Shyirak massif, located in the Inner Tien Shan, are not only affected by climate change, but also impacted by the open pit gold mining of the Kumtor Gold Company. In this study, glacier inventories referring to the years 2003 and 2013 were created for the Ak-Shyirak massif based on satellite imagery. The 193 glaciers had a total area of 351.2±5.6km(2) in 2013. Compared to 2003, the total glacier area decreased by 5.9±3.4%. During 2003-2013, the shrinkage rate of Ak-Shyirak glaciers was twice than that in 1977-2003 and similar to shrinkage rates in Tien Shan frontier ranges. We assessed glacier volume in 2013 using volume-area (VA) scaling and GlabTop modelling approaches. Resulting values for the whole massif differ strongly, the VA scaling derived volume is 30.0-26.4km(3) whereas the GlabTop derived volume accounts for 18.8-13.2km(3). Ice losses obtained from both approaches were compared to geodetically-derived volume change. VA scaling underestimates ice losses between 1943 and 2003 whereas GlabTop reveals a good match for eight glaciers for the period 2003-2012. In comparison to radio-echo soundings from three glaciers, the GlabTop model reveals a systematic underestimation of glacier thickness with a mean deviation of 16%. GlabTop tends to significantly underestimate ice thickness in accumulation areas, but tends to overestimate ice thickness in the lowermost parts of glacier snouts. Direct technogenic impact is responsible for about 7% of area and 5% of mass loss for glaciers in the Ak-Shyirak massif during 2003-2013. Therefore the increase of summer temperature seems to be the main driver of accelerated glacier shrinkage in the area. PMID:27100016

    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.

    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.

    The Ysyk-Köl Basin filled with Lower Jurassic-Quaternary sedimentary rocks is the largest intermontane negative structural unit of the northern Tien Shan. The basement of this basin is composed of Precambrian-Paleozoic rocks, largely of Ordovician and Silurian granitoids exposed in mountain ranges of the basin framework and as separate anticlinal domes situated in areas occupied by the Mesozoic-Cenozoic sedimentary cover. The postmagmatic tectonic internalstructure of the Chonkurchak (Chunkurchak), Kyzyl-Choku, Kyzyl-Bulak, and Prishib massifs emplaced in the basement, as well as their relationships to the sedimentary cover, are described in the paper. The study was carried out using the morphostructural method, detailed geological mapping, structural kinematic analysis, and petrographic examination of rocks. The internalstructure of Paleozoic granites in the basement and indications of their 3D tectonic flow are characterized. It is shown that granites underwent 3D deformation after their emplacement in the consolidated crust, and this process had a substantial influence on tectonic processes at the plate and orogenic stages of regional evolution.

  18. An investigative study into the effectiveness of using computer-aided instruction (CAI) as a laboratory component of college-level biology: A case study

    Barrett, Joan Beverly

    Community colleges serve the most diverse student populations in higher education. They consist of non-traditional, part-time, older, intermittent, and mobile students of different races, ethnic backgrounds, language preferences, physical and mental abilities, and learning style preferences. Students who are academically challenged may have diverse learning characteristics that are not compatible with the more traditional approaches to the delivery of instruction. With this need come new ways of solving the dilemma, such as Computer-aided Instruction (CAI). This case study investigated the use of CAI as a laboratory component of college-level biology in a small, rural community college setting. The intent was to begin to fill a void that seems to exist in the literature regarding the role of the faculty in the development and use of CAI. In particular, the investigator was seeking to understand the practice and its effectiveness, especially in helping the under prepared student. The case study approach was chosen to examine a specific phenomenon within a single institution. Ethnographic techniques, such as interviewing, documentary analysis, life's experiences, and participant observations were used to collect data about the phenomena being studied. Results showed that the faculty was primarily self-motivated and self-taught in their use of CAI as a teaching and learning tool. The importance of faculty leadership and collegiality was evident. Findings showed the faculty confident that expectations of helping students who have difficulties with mathematical concepts have been met and that CAI is becoming the most valuable of learning tools. In a traditional college classroom, or practice, time is the constant (semesters) and competence is the variable. In the CAI laboratory time became the variable and competence the constant. The use of CAI also eliminated hazardous chemicals that were routinely used in the more traditional lab. Outcomes showed that annual savings

    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 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

    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

    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.

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

    2015-11-01

    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

    Full Text Available Abstract Background Advanced cancer is a multifactorial disease that demands treatments targeting multiple cellular pathways. Chinese herbal cocktail which contains various phytochemicals may target multiple dys-regulated pathways in cancer cells and thus may provide an alternative/complementary way to treat cancers. Previously we reported that the Chinese herbal cocktail Tien-Hsien Liguid (THL can specifically induce apoptosis in various cancer cells and have immuno-modulating activity. In this study, we further evaluated the anti-metastatic, anti-angiogenic and anti-tumor activities of THL with a series of in vitro and in vivo experiments. Methods The migration and invasion of cancer cells and endothelial cells was determined by Boyden chamber transwell assays. The effect of THL on pulmonary metastasis was done by injecting CT-26 colon cancer cells intravenously to syngenic mice. The in vitro and in vivo microvessel formation was determined by the tube formation assay and the Matrigel plug assay, respectively. The in vivo anti-tumor effect of THL was determined by a human MDA-MB-231 breast cancer xenograft model. The expression of metalloproteinase (MMP-2, MMP-9, and urokinase plasminogen activator (uPA was measured by gelatin zymography. The expression of HIF-1α and the phosphorylation of ERK1/2 were determined by Western blot. Results THL inhibited the migration and invasion ability of various cancer cells in vitro, decreased the secretion of MMP-2, MMP-9, and uPA and the activity of ERK1/2 in cancer cells, and suppressed pulmonary metastasis of CT-26 cancer cells in syngenic mice. Moreover, THL inhibited the migration, invasion, and tube formation of endothelial cells in vitro, decreased the secretion of MMP-2 and uPA in endothelial cells, and suppressed neovascularization in Matrigel plugs in mice. Besides its inhibitory effect on endothelial cells, THL inhibited hypoxia-induced HIF-1α and vascular endothelial growth factor-A expression

    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

    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. Relative carrier-phase GPS surveys reveal a vertical lowering 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 current state are 289 mm and −3.8 °C at the glacier summit (4600 m a.s.l., respectively. The good agreement between dynamically derived precipitation and the long-term observed precipitation at a nearby station in the Tien Shan (296 mm at 3614 m a.s.l. for the period 1930–2002 suggests that the glacier has been in a near steady-state in terms of mass supply. 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.

    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.

    2016-03-01

    We carried out archaeoseismological studies in the Southern Issyk-Kul region (Kyrgyz Tien Shan) and obtained radiocarbon datings of the collected samples. These data suggest that the sources of strong earthquakes have occurred in this territory in the 11th and (probably) 16th centuries. These earthquakes had magnitude M ≥ 7 and seismic intensity of at least I ≥ 9. The sources of these earthquakes were associated with the local adyr (piedmont) faults—components of the Pre-Terskei border fault. Our results demonstrate considerable underestimation of the seismic hazard for the South Issyk-Kul region in the latest Seismic Zoning Map of Kyrgyz Republic (2012), which should be taken into account in the construction of the new seismic zoning map for Kyrgyzstan.

    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.

  3. Repeated large-magnitude earthquakes in a tectonically active, low-strain continental interior: The northern Tien Shan, Kyrgyzstan

    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.

    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。

    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

  11. Bursts of gamma-rays, electrons and low-energy neutrons during thunderstorms at the Tien-Shan

    International Nuclear Information System (INIS)

    New data of the last measurement season held at the Tien-Shan complex for investigation gamma-radiation, accelerated electrons and low-energy neutrons during thunderstorms are presented. The flux of gamma-radiation in the energy range of 40 – 1200 keV shows a strict correlation with instantaneous intensity of atmospheric discharge. Its energy spectra measured for the first time with riches statistics and improved resolution typically have an absolute intensity about 50 – 100 quanta·cm−2·s−1, and demonstrate considerable evolution in the course of discharge. The signals from an avalanche of accelerated electrons have been directly observed inside thunderclouds. A lower energy estimation for these electrons is about 10 MeV. For the first time, during electric discharge moments in thunderstorms, there were found considerable intensity enhancements of the neutron intensity in the range of thermal energies: up to 100 – 200 standard deviations, or 3 – 8 times above the background, so the observed neutron flux reaches the values of (20 – 40) · 103 m−2 · min−1.

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

    N. V. Tarasova

    2004-06-01

    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.

    Shear wave velocity structure across the central Tien Shan orogeny was generated by jointly inverting Rayleigh wave phase and group velocity with teleseismic P-wave receiver functions at 40 broadband seismic stations. The inferred seismic structure was validated by forward modeling of the complete Bouguer anomaly data. The joint inversion result reveals larger crust thicknesses beneath the Kokshaal (∼68-72 km) and Kyrgyz ranges (∼62-64 km), while other units have crustal thicknesses between 48 and 58 km. A fast velocity layer (Vs = 3.6-3.9 km/s) in the upper crust is found in some seismic stations within the Kazakh Shield. Our models show the presence of high velocity and density layers in the lowermost crust throughout the region, consistent with the presence of mafic/ultramafic lithologies. The large crustal thickness is associated with a thickened mafic layer in the lower crust, indicating that the thickened crust may be partly caused by magmatic underplating. The low velocity and density anomaly in the middle crust, and low upper mantle velocity observed in our model beneath the middle Tien Shan reflect the presence of partial melt in the crust due to the intrusion of hot mantle material. The lack of correlation between Moho depth and topography, together with the gravity results, suggests that the topographic compensation in the central Tien Shan is not confined to the crust. This requires significant support from the mantle to account for the relative high elevation of the middle Tien Shan.

Los autores de estas obras establecen las bases para el desarrollo de toda una temática que gira alrededor del Grial a partir del siglo XII hasta nuestros días. El artículo muestra cómo de un objeto apenas sagrado en el texto de Chrétien de Troyes se pasa a una reliquia de la sangre de Cristo en la versión de Robert de Boron.This paper studies the literary origin of the Grail legend in medieval French literature, taking into account two important romances: Le Conte du Graal by Chrétien de Troyes and Le Roman de l’Estoire dou Graal by Robert de Boron. In these two texts the authors established the basis for the development of a new subject matter around the mysterious object called “Grail” from the Middle Ages to the present times. It will also be shown how an object, not totally sacred in Chrétien de Troyes, becomes a relic related with Jesus’s blood in Robert de Boron.

  16. 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

    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

    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 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.

    PLACs (platy hibonite crystals) and related hibonite-rich calcium-, aluminum-rich inclusions (CAIs; hereafter collectively referred to as PLAC-like CAIs) have the largest nucleosynthetic isotope anomalies of all materials believed to have formed in the solar system. Most PLAC-like CAIs have low inferred initial 26Al/27Al ratios and could have formed prior to injection or widespread distribution of 26Al in the solar nebula. In this study, we report 26Al-26Mg systematics combined with oxygen, calcium, and titanium isotopic compositions for a large number of newly separated PLAC-like CAIs from the Murchison CM2 chondrite (32 CAIs studied for oxygen, 26 of these also for 26Al-26Mg, calcium and titanium). Our results confirm (1) the large range of nucleosynthetic anomalies in 50Ti and 48Ca (our data range from -70‰ to +170‰ and -60‰ to +80‰, respectively), (2) the substantial range of Δ17O values (-28‰ to -17‰, with Δ17O = δ17O - 0.52 × δ18O), and (3) general 26Al-depletion in PLAC-like CAIs. The multielement approach reveals a relationship between Δ17O and the degree of variability in 50Ti and 48Ca: PLAC-like CAIs with the highest Δ17O (∼-17‰) show large positive and negative 50Ti and 48Ca anomalies, while those with the lowest Δ17O (∼-28‰) have small to no anomalies in 50Ti and 48Ca. These observations could suggest a physical link between anomalous 48Ca and 50Ti carriers and an 16O-poor reservoir. We suggest that the solar nebula was isotopically heterogeneous shortly after collapse of the protosolar molecular cloud, and that the primordial dust reservoir, in which anomalous carrier phases were heterogeneously distributed, was 16O-poor (Δ17O ⩾ -17‰) relative to the primordial gaseous (CO + H2O) reservoir (Δ17O < -35‰). However, other models such as CO self-shielding in the protoplanetary disk are also considered to explain the link between oxygen and calcium and titanium isotopes in PLAC-like CAIs.

    Paleomagnetic study on the Cenozoic volcanic rocks from the Tuoyun Basin of the southwest Tien Shan indicates that most samples could isolate a stable characteristic remanent magnetization with reversed polarity. The positive fold test suggests that the characteristic component is very likely to be a primary magnetization acquired in the formation of rocks. Comparison with the reference Eurasia poles at 60 Ma indicates little or insignificant N-S convergence between the south edge of southwest Tien Shan and Siberia since the onset of the India/Asia collision at the Eocene. Furthermore, the Cretaceous and Tertiary paleomagnetic results suggest that the Tuoyun Basin was subjected to a local clockwise rotation of 20 . -35 . With respect to Eurasia since the Paleocene time, which is probably subsequent to the Cenozoic northward compression of the Pamir arc.

    Snow algae are photosynthetic microorganisms and are living on the surfase of glaciers. They grow on melting surface from spring to summer and their biomass and community structure are changed with physical and chemical conditions on glaciers. Ice cores drilled from glaciers also contain snow algae that grew in the past. Studying biomass and community structure of snow algae in ice cores could reveal the temporal variation in snow algae in the past, and also environmental conditions relating propagation of snow algae. In this study, we anlalyzed snow algae preserved in an ice core of Grigoriev Ice cap located in eastern Kyrgyzstan of the central Asia, and to describe their temporal variations for the last 200 years. The ice core drilling was carried out on September in 2007 on the Grigoriev Ice cap in the Kyrgyz Tien Shen Mountains. A 87 m long ice core from the surface to the bedrock was recovered at the top of the ice cap. The core was horizontally cut every 5 cm (total 1212 samples). The samples were melted and preserved as a 3% formalin solution. After the sample water was filtered through a hydrophilized PTFE membrane filter, observed by microscope. Snow algae in the sample water were counting. The algal biomass was represented by the cell number per unit water volume. Here, we showed the results between the surface to the 64 m in depth. We also analyzed the snow algal communities on the surface of the ice cap collected from five different sites from the top down to the terminus. Microscopy revealed that the ice core contained three taxa of filamentous cyanobacteria, an unicellular cyanobacterium, and two green algae. They were also found on the ice or snow surface of the i Ice cap. The quantitative analyses of the algae in the part of upper 64 m deep of the ice core samples revealed that the algal biomass varied significantly and showed many peaks. Furthermore, the biomass profile differed among the taxa. The filamentous cyanobacterium varied from 0.0 to 4

    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.

    We have carried out a FIB/TEM study of refractory CAI-like objects in one AOA from the ALHA77307 CO3.0 chondrite. The CAI-like objects in the AOA consist of a zoned sequence with a spinel-rich core through an intergrowth layer of spinel and Al-Ti-rich diopside to a diopside rim. The spinel-rich core consists of polycrystalline aggregates of spinel and ±minor melilite showing equilibrated grain boundary textures. The intergrowth layer contains fine-grained diopside and spinel with minor anorthite with highly curved and embayed grain boundaries. The diopside rim consists of polycrystalline aggregates of diopside. The compositions of pyroxene change significantly outward from Al-Ti-rich diopside in contact with the spinel-rich core to Al-Ti-poor diopside next to the surrounding olivine of the AOA. Overall microstructural and chemical characteristics suggest that the spinel-rich core formed under equilibrium conditions whereas the intergrowth layer is the result of reactions that occurred under conditions that departed significantly from equilibrium. The remarkable changes in formation conditions of the CAI-like objects may have been achieved by transport and injection of refractory objects into a region of a partially-condensed, Ca,Ti-saturated gas which reacted with spinel and melilite to form Al-Ti-rich diopside. Crystallographically-oriented TiO2 nanoparticles decorate the grain boundaries between spinel grains and between spinel and Al-Ti-rich diopside grains. During the disequilibrium back-reaction of spinel with a partially-condensed, Ca,Ti-saturated gas, metastable TiO2 nanoparticles may have condensed by an epitaxial nucleation mechanism and grown on the surface of spinel. These TiO2 nanoparticles are disordered intergrowths of the two TiO2 polymorphs, anatase and rutile. These nanoparticles are inferred to have nucleated as anatase that underwent partial transformation into rutile. The local presence of the TiO2 nanoparticles and intergrowth of anatase and

    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.

  1. Registration of intensive hard X-rays and soft gamma-rays from the thunderstorm clouds at Tien-Shan installation Adron

    International Nuclear Information System (INIS)

    The Adron installation mounted at the Tien-Shan station is intended for studying the extensive air showers. The Adron installation consists of a neutron supermonitor charged particles detector, muon detector and detector for registering the hard X-ray and soft gamma-radiation from the thunderstorm clouds accomplished on the basis of the Geiger-Mueller counters with sensitivity area of 16-17 m2. The intensive fluxes of the hard X-ray and soft gamma-radiation from the thunderstorm clouds passing over the Adron installation at the height below 1 km are registered using this installation. The short-time radiation flares of 1-5 min duration are separated at the background of the intensity slow change. This testifies to the benefit of existence of the runaway electron effect in the thunderstorm clouds

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.

  11. Intraplate mountain building in response to continent continent collision—the Ancestral Rocky Mountains (North America) and inferences drawn from the Tien Shan (Central Asia)

    The intraplate Ancestral Rocky Mountains of western North America extend from British Columbia, Canada, to Chihuahua, Mexico, and formed during Early Carboniferous through Early Permian time in response to continent-continent collision of Laurentia with Gondwana—the conjoined masses of Africa and South America, including Yucatán and Florida. Uplifts and flanking basins also formed within the Laurentian Midcontinent. On the Gondwanan continent, well inboard from the marginal fold belts, a counterpart structural array developed during the same period. Intraplate deformation began when full collisional plate coupling had been achieved along the continental margin; the intervening ocean had been closed and subduction had ceased—that is, the distinction between upper versus lower plates became moot. Ancestral Rockies deformation was not accompanied by volcanism. Basement shear zones that formed during Mesoproterozoic rifting of Laurentia were reactivated and exerted significant control on the locations, orientations, and modes of displacement on late Paleozoic faults. Ancestral Rocky Mountain uplifts extend as far south as Chihuahua and west Texas (28° to 33°N, 102° to 109°W) and include the Florida-Moyotes, Placer de Guadalupe-Carrizalillo, Ojinaga-Tascotal and Hueco Mountain blocks, as well as the Diablo and Central Basin Platforms. All are cored with Laurentian Proterozoic crystalline basement rocks and host correlative Paleozoic stratigraphic successions. Pre-late Paleozoic deformational, thermal, and metamorphic histories are similar as well. Southern Ancestral Rocky Mountain structures terminate along a line that trends approximately N 40°E (present coordinates), a common orientation for Mesoproterozoic extensional structures throughout southern to central North America. Continuing Tien Shan intraplate deformation (Central Asia) has created an analogous array of uplifts and basins in response to the collision of India with Eurasia, beginning in late

    A search for the possible precursors of an earthquake and its effect on the data series of diverse geophysical parameters has been made in the mountain of Northern Tien Shan. The complex installation included the NM64 type neutron supermonitor, detectors of the environmental low-energy neutrons, the scintillation gamma-detector, the sensor of the local electric field, a seismograph, and a weather-station. The specialized data filtration methodic was elaborated with an enhanced sensitivity to the transient signals of seismic origin. On the eve of, and after a 5.4 magnitude earthquake the fine features in temporal behavior of the intensity of low-energy neutron and gamma-radiation background, so as irregularities of the local electric field were observed which seem to be in a close correlation with each other. These results may be an evidence of the possibility of experimental identification of earthquake's precursors in the time up to 2-3 days before the beginning of a period of intensive tectonic activity.

    Full Text Available There are increasing pieces of evidence suggesting that the recurrence of cancer may result from a small subpopulation of cancer stem cells, which are resistant to the conventional chemotherapy and radiotherapy. We investigated the effects of Chinese herbal mixture Tien-Hsien Liquid (THL on the cancer stem-like side population (SP cells isolated from human hepatoma cells. After sorting and subsequent culture, the SP cells from Huh7 hepatoma cells appear to have higher clonogenicity and mRNA expressions of stemness genes such as SMO, ABCG2, CD133, β-catenin, and Oct-4 than those of non-SP cells. At dose of 2 mg/mL, THL reduced the proportion of SP cells in HepG2, Hep3B, and Huh7 cells from 1.33% to 0.49%, 1.55% to 0.43%, and 1.69% to 0.27%, respectively. The viability and colony formation of Huh7 SP cells were effectively suppressed by THL dose-dependently, accompanied with the inhibition of stemness genes, e.g., ABCG2, CD133, and SMO. The tumorigenicity of THL-treated Huh7 SP cells in NOD/SCID mice was also diminished. Moreover, combination with THL could synergize the effect of doxorubicin against Huh7 SP cells. Our data indicate that THL may act as a cancer stem cell targeting therapeutics and be regarded as complementary and integrative medicine in the treatment of hepatoma.

    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

    蔡襄是中国历史名臣,素有北宋第一谏官之盛誉。蔡襄从政30多年,勤政廉政,克己奉公,堪称一代清官廉吏。蔡襄的勤政廉政实践主要表现四个方面:一是“为官一任,造福一方”的勤政实践;二是“民重君轻”、“固本安帮”的民本思想;三是惩治腐败、两袖清风的廉政思想;四是刚正不阿、忠于职守的社会责任感和历史使命感。在新的历史条件下,弘扬借鉴蔡襄勤政廉政实践,以史为鉴,继往开来,仍然具有重要的历史意义和现实意义。%Cai Xiang who was a famous minister in Chinese history had a good reputation of first expostulate officer in Northern Song. During Cai Xiang’s thirty years in politics, he kept a diligent and honest government, selfless for the public interest, may be called a generation of honest an upright official officer. Cai Xiang’s practice of keeping a diligent and honest government mainly includes four aspects: firstly, the diligent practice for “the official term, the benefit of a party”; secondly, people-based thought for“civil rights, solid intrinsically safe help”;thirdly, the honest government thought for “punishing corruption, the sleeves swaying with every soft breeze”;fourthly, the sense of social responsibility and history mission for“upright and outspoken, be loyal to their duties”. In the new historical conditions, carrying forward Cai Xiang’s practice of keeping a diligent and honest government, taking history as a mirror towards the future still have important historical and realistic significance.

    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).

Applying the method of differences, it confronts several historical occasions when millennialism was either promoted or condemned: during the first centuries of Christianity, particularly with Saint Augustine in the 1Vth century; Joachim de Flore in the XIIIth century; Thomas Munzer and the Anabaptist Commune in the 1960-70s. The comparison casts light on various temporal configurations of the Utopia of the End of Time.

  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.

    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。

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.

    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...

    2011-01-01

    In the history of both east and west plays, similarities in historical contexts brought about similar typical thinkers. Hamlet, an image depicted in the Elizabethan period, represented the ideal tragedy in the eyes of humanists. He becomes a common name of global significance characterized by melancholy and procrastination. Cai Bojie in Chinese classical play The Story of the Lute is similar to Hamlet in that he is laden with heavy reflections of human beings and a character endowed with great cultural elements. Therefore, these two images are quite comparable. Beyond their similarities, they differ greatly in their endings, reflecting the difference in western and eastern concepts of plays and cultural traditions.%东、西方戏剧史上,相似的历史背景下出现了相似的思考者典型。英国伊丽莎白时期诞生的哈姆雷特形象以人生的负重者出现,他的个人悲剧代表了当时人文主义者的理想悲剧,他以忧郁、延宕的性格成为具有世界意义的共名。中国明代古典戏剧《琵琶记》中的蔡伯喈,背负沉重的人生思考,包涵深厚的文化性格,与哈姆雷特具有很强的可比性。二剧皆对主要人物延宕为主的性格进行渲染,并由此展开尖锐的戏曲冲突,但矛盾的调解方式及结局却大相径庭,由此烛照出东西方文化传统与戏剧观念的差异。

    “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.

    Full Text Available The Chinese herbal mixture, Tien-Hsien Liquid (THL, has been proven to suppress the growth and invasiveness of cancer cells and is currently regarded as a complementary medicine for the treatment of cancer. Our previous study using acute promyelocytic leukemia cells uncovered its effect on the downregulation of DNA methyltransferase 1 (DNMT1 which is often overexpressed in cancer cells resulting in the repression of tumor suppressors via hypermethylation. Herein, we explored the effects of THL in MCF-7 breast cancer cells that also demonstrate elevated DNMT1. The results show that THL dose-dependently downregulated DNMT1 accompanied by the induction of tumor suppressors such as p21 and p15. THL arrested cell cycle in G2/M phase and decreased the protein levels of cyclin A, cyclin B1, phospho-pRb, and AKT. DNMT1 inhibition was previously reported to exert a radiosensitizing effect in cancer cells through the repression of DNA repair. We found that THL enhanced radiation-induced clonogenic cell death in MCF-7 cells and decreased the level of DNA double-strand break repair protein, Rad51. Our observations may be the result of DNMT1 downregulation. Due to the fact that DNMT1 inhibition is now a mainstream strategy for anticancer therapy, further clinical trials of THL to confirm its clinical efficacy are warranted.

    In vitro hippocampal slices were prepared from neonate rats (3 ~ 5 days old). Whole-cell patch-clamp re-cordings were obtained from CAI neurons by using voltage-clamp technique combined with biocytin intracellular staining method to study the relationship between the evoked synaptic responses and the dendritic arborization of pyramidal neurons. We reported that during the period of P3 ~ 5 pyramidal neurons were morphologically heterogeneous. Fifty-two percent of the neurons had poorly branched apical dendrites, with neither spontaneous nor evoked postsynaptic currents (PSCs); 48% of the neurons had much more developed dendritic arborization and synaptic responses when stimulation electrode was positioned in the stratum radiatum. Furthermore, the amplitudes of PSCs evoked at half-maximal intensity of stimuli positively correlated with the apical dendritic length and number of terminal branches. The present results demonstrate that the apical dendritic arborization relates to the responsiveness of CA1 pyramidal neurons to stimulation of stratum radiatum.%应用盲法脑片膜片钳记录并结合biocytin细胞内染色方法,研究了新生大鼠(生后3~5 d)离体海马脑片CA1锥体神经元突触反应和树突分枝的关系.发现,在生后3~5 d锥体神经元的形态呈现多形性.52%的神经元具有分枝很少的树突,并且既无自发性也无诱发性的突触后电流(postsynaptic currents,PSCs);48%的神经元具有较为发达的树突分枝且当刺激海马辐射层时,可引起突触反应.而且在半最大刺激强度时引起的PSCs的幅值与神经元顶树突的长度及终末分枝数呈正相关.上述研究结果表明,CAl锥体神经元的反应性是与顶树突的分枝状况相关的.

    Full Text Available La Farce de maître Pathelin, Pantagruel et le Cymbalum mundi présentent tous trois un personnage qui a la particularité de communiquer pour ne pas se faire comprendre alors qu’il a la possibilité de le faire en toute intelligence avec ses interlocuteurs. Pathelin et Panurge s’expriment en langues et les chiens du Cymbalum mundi aboient alors qu’ils savent parler. Cet article explore les modalités et les motivations de ce refus de « parler chrétien », à travers ces trois œuvres de la fin du Moyen-Âge et du début de la Renaissance où la valeur du langage, gloire de l’humain, fondement de la société, est remise en question.La Farce de maître Pathelin, Pantagruel and the Cymbalum mundi each involve a character whose distinctive feature is that he communicates so as not to make himself understood, when he is perfectly able to make himself understood to the people he is addressing. Pathelin and Panurge speak in tongues and the dogs from the Cymbalum mundi bark whereas they can speak. This article investigates the workings and motivations of this refusal to « speak Christian », through three works from the end of the Middle Ages and the beginning of the Renaissance in which the value of language as human glory and foundation of society is questioned.

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 ?

    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 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.

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.

    In the early 1920s of the last century, Norwegian writer Ibsen’s work A Doll’s housewas introduced in Korea, where the heroine “Nora” attracted much attention. 10 years later, Cai Wanzhi, a Korean writer, wrote a sequel namedAfter Leaving the Doll’s House in 1993. So far, the Korean scholars argue that the two works share the same strain. The latter actually intensifies the idea “Emancipation of women”. However, the idea the article holds is that Cai Wanzhi shaped an image of “new political subject” by means of the much-talked-about character “Nora”, who had been symbolized under “the women issue”. Meanwhile he also tried to dig up the political line along which the Korean folks toiled for survival under the colonial background. At the end of the ifction, “Nora”, a middle class lady, converted into a proletarian worker dramatically. In fact, it is a mechanical mixture of ideology and novel fodder. The author's delicate deceitful act made his works accepted by the Japanese colonial governmental publication inspection system successfully. It can be said that the change of “Nora”image is the concentrated relfection of the transformation of ideology and arts of Korean literature in 1930s and shows a new expressive way of the proletarian literature.%上世纪20年代初,易卜生的《玩偶之家》被介绍到韩国,主人公“娜拉”作为“自由女性像”受到广泛的关注。十余年后的1933年,作家蔡万植以翻案的形式创作了小说《走出玩偶之家后》。迄今为止,韩国学界普遍认为作品中的“娜拉”是对前者妇女解放思想的继承和强化。然而,小说中的“娜拉”在历经种种人生的磨难后,最终从中产阶级夫人转变为一个自食其力的无产阶级工人,这一变身的结局具有深刻的寓意。本文认为,作者蔡万植把当时敏感的社会主义意识形态问题巧妙地嫁接到妇女解放的传统主题里,借助当时已

    Full Text Available Since 1995, a barren rock has been formed at the Davydov Glacier, due to the works at the Kumtor Gold Mine. By the end of 2010, total amount of the rock, stockpiled on the glacier, apparently exceeded 200 million tons, the height of dumps of rock sometimes exceeded 50 meters. The most noticeable effects of this are provoking local surges of the Davydov Glacier and squeezing glacier ice out of the dumps of rock. For a detailed analysis of both processes, we also used the results of periodic geodetic measurements (over 8000 of monitoring rods (about 800 rods of the gold mining company. A number of local surges of the glacier has been found, the first of which began in March–April 2002. To analyze glacier squeezing out of the dumps of rock, mathematical modeling of that process has been done. It was established that in most cases, the glacier is almost completely squeezed out of for 1–2 years.

    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.

  9. 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.

    Since 1995, a barren rock has been formed at the Davydov Glacier, due to the works at the Kumtor Gold Mine. By the end of 2010, total amount of the rock, stockpiled on the glacier, apparently exceeded 200 million tons, the height of dumps of rock sometimes exceeded 50 meters. The most noticeable effects of this are provoking local surges of the Davydov Glacier and squeezing glacier ice out of the dumps of rock. For a detailed analysis of both processes, we also used the results of periodic ge...

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

    2008-05-18

    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.

    Some visually impaired children have difficulty in simple locomotion, and need orientation and mobility training. We developed a computer assisted instruction system which assists this training. A user realizes a task given by a tactile map and synthesized speech. The user walks around a room according to the task. The system gives the gap of walk path from its target path via both auditory and tactile feedback after the end of a task. Then the user can understand how well the user walked. We describe the detail of the proposed system and task, and the experimental result with three visually impaired children.

    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. El reclutamiento se comenzó con 16 participantes llamados semillas. Se realizó el diagnóstico de infección por HIV, hepatitis B y C (HBV y HCV), Treponema pallidum, Virus Papiloma Humano (HPV) y Chlamidias. La colaboración establecida entre los grupos de trabajo enfocados en áreas diversas posibilitó el abordaje conjunto de nuevas estrategias de investigación antes no exploradas en nuestro país.

  2. Impact of varying debris cover thickness on catchment scale ablation: a case study for Koxkar glacier in the Tien Shan

    2013-11-01

    Full Text Available To quantify the ablation processes on a debris covered glacier, a simple distributed ablation model has been developed and applied to a selected glacier. For this purpose, a bundle of field measurements was carried out to collect empirical data. A morphometric analysis of the glacier surface enables us to statistically capture the areal distribution of topographic features that influence debris thickness and consequently ablation. Remote sensing techniques, using high resolution satellite imagery, were used to extrapolate the ground truth results to the whole ablation area and to map and classify melt-relevant surface types. As a result, a practically applicable method is presented, that allows the estimation of ablation on a debris covered glacier by combining field data and remote sensing information. The sub-debris ice ablation accounts for about 19% of the entire ice ablation, while the percentage of the moraine covered area accounts for approximately 32% of the entire glacerized area. Although the ice cliffs occupy only 1.7% of the debris covered area the melt amount accounts for approximately 15% of the total sub-debris ablation and 2.7% of the total ablation respectively. Our study highlights the influence of debris cover on the response of the glacier terminus to climate warming. Due to the fact that melt rates beyond 0.1m of moraine cover are highly restricted the shielding effect of the debris cover dominates over the temperature- and elevation dependence of the ablation in the bare ice case.

    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.

    Full Text Available This study aims to reveal the impressions that youth have of bibliotecology as a career, what barriers are presented to those who enter the profession and what attracts them the same. 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.

No es una simple misiva lo anhelado, es la posibilidad de salir del mero registro en la contabilidad de una economía aniquilante, del conteo de los bienes; es la búsqueda de un espacio para inscribir la vida y la muerte más allá de la repetición constante de los mismos padecimientos que toman dimensiones sociales. Que el suyo sea un caso literario no obsta para que encontremos en él, junto con otros en nuestras letras colombianas, las luces que nos obligan a tomarlo de manera literal. Fue esta lectura la que roo movió a escribirle estas líneas; espero no haberlo importunado con ellas y que comprenda lo que me animó apresentarle la interpretación que en mí suscitó la suya.

    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.

  17. Provenance research of the archaeological earthenware collected at Cat Tien relic by nuclear analytical methods and multivariate statistics

    International Nuclear Information System (INIS)

    In this research, methods of INAA, XRF, AAS combined with the multivariate statistics have been applied for provenance search of the earthenware at the Cattien relic. About 34 elements in 363 samples have been characterized. Number of samples are 111; 16; 158; 65; 10 and 3 for clay; sand; ancient brick; ancient ceramic; ancient tile and agglutinative substance, respectively. The sampling area was 12,600 ha, 30 km in length along Dongnai river belonging to Dateh, Cattien districts of Lamdong province and Tanphu district of Dongnai province. Three reference clay sources with area of approximately 500 ha at Quangngai town, Cattien have been localized and classified. Multivariate statistics such as CA, PCA, CD, MD were applied to analyze set of data. The results showed that: The C2 field is a combination of 3 different sources of clay that are the riverside, the field center and the hill base rather than a homogenous source. These three sources are characterized by indicator elements such as Mn (PC1, PC4), As (PC1, PC3), Ba (PC2) and Tb (PC2), in which pair of Mn - As is the most important. Through multivariate analysis, clay from riverside of the C2 field was identified to be the source of 93% of the ancient brick used to build twelve towers 2A, 2B, 2C, 2D (2D1, 2D2), 3, 4, 6A, 6B, 7, 8A, 8B and C out of 14 towers at Cattien relic. On the other hand, it is found that there is no clear relation between the bricks collected at the relic and those at Bay-Mau field. Distribution of ancient pottery and tile is quite diverse, therefore, their source has not been found in this study. (author)

    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 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.

    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.

    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 RESUMEN: la construcción de la identidad nacional vasca ha recurrido a los más variados elementos para su formación, con el rasgo añadido de que ha tenido que convivir, resistir o diferenciarse de otras identidades cercanas y presentes en el mismo territorio. Es necesario partir de esta premisa para analizar los diversos planos en los que se ha construido la identidad nacional vasca en el ámbito educativo: el primer plano administrativo y escolar; el segundo, desde la elaboración de un currículo vasco y, finalmente, desde las actividades extraescolares. Hemos preferido elegir un periodo de tiempo lo suficientemente largo para poder mostrar los cambios y las continuidades en su construcción, partiendo desde 1876, con la pérdida de los Fueros, hasta la Segunda República. Se trata de un periodo en el que se fragua la construcción nacional vasca, priorizando unos elementos culturales y étnicos, sobre la base de la lengua vasca.ABSTRACT: The construction of Basque national identity has made use of a wide range of elements, in addition to which Basque identity has had to co-exist with, resist, or distinguish itself from neighbouring identities as well as identities present within the same territory. It is necessary to begin with this premise in order to analyze the various levels on which Basque national identity has been built within the sphere of education: firstly, in the administrative and educational sphere; secondly, in drawing up a Basque curriculum; and finally, in extracurricular activities. We have chosen to focus on a period that would be long enough to demonstrate both continuity and change during the process of construction. This period ranges in time from the loss of the Fueros (Traditional Basque Law in 1876, until the advent of the Second Republic in Spain in 1931. It was during this time that the Basque nation was forged, with priority being given to cultural and ethnic elements and using the Basque language as a foundation.

    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.

  18. The 24 July 2008 outburst flood at the western Zyndan glacier lake and recent regional changes in glacier lakes of the Teskey Ala-Too range, Tien Shan, Kyrgyzstan

    On 24 July 2008, a glacier lake outburst flood (GLOF) occurred at the western (w-) Zyndan glacier lake in the Tong District of Ysyk-Köl Oblast, Kyrgyzstan. 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 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.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.

    Directory of Open Access Journals (Sweden)

    Pedro Monsanto

    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.

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.

    Agricultural irrigation using the waste waters generated in the industrial sugar production process is the most commonly employed way of treating and depositing of such waste once of has been suitably homogenized. However, this solution also has its limitations. It is therefore necessary to characterise the different waste water currents, especially the saline currents, so that they can be segregated, thereby allowing fertirrigation to take into account the need to preserve the structure of the soil and ensure the viability of the type of crop being grown. A set of analytical techniques for determining the ionic composition of these waters is presented which facilitate decisions on how best to manage them in the future. (Author) 10 refs.

    2008-07-01

    Full Text Available In this experimental study, use of Computer Assisted Instruction (CAI followed by use of an Intelligent Tutoring System (CAI+ITS was compared to the use of CAI (CAI only in tutoring students on the topic of Algebraic Expression. Two groups of students participated in the study. One group of 32 students studied algebraic expression in a CAI learning environment, while the other group of 30 students was in a CAI and ITS (CAI+ITS environment. Before the experimental treatment began, subjects were given a pre-test on algebraic expression. A post-test was also given at the end of the study. The experimental treatment was administered in eight sessions with one hour per session. For the first stage of the study, both groups of subjects studied algebraic expression in a CAI environment. In the second stage, subjects from the CAI group continued with a tutoring session using the drill and practice section of the CAI package, whereas subjects from the CAI+ITS environment continued their learning using the ITS tutorial. The results of the study showed that there was a significant difference in the students’ achievement in algebraic expression between students who learned with CAI+ITS and who learned with CAI only as the delivery system. The findings of the study indicated that CAI+ITS was more effective in helping students learn algebraic expression as compared to using CAI alone. This study suggests that educators and software developers should focus on the development of ITS based learning tools or integrate ITS elements in courseware development rather than developing a mere CAI tool.

    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 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. PMID:27246620

    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.

    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.

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.

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.

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 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 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.

    2015-01-01

    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 ...

    , FUN CAIs may provide a unique window into the earliest Solar System, including the origin of short-lived radioisotopes. However, their chronology is unknown. Using the 182Hf–182W chronometer, we show that a FUN CAI recording a condensation origin from a solar gas formed coevally with canonical CAIs......Refractory inclusions [calcium–aluminum-rich inclusions, (CAIs)] represent the oldest Solar System solids and provide information regarding the formation of the Sun and its protoplanetary disk. CAIs contain evidence of now extinct short-lived radioisotopes (e.g., 26Al, 41Ca, and 182Hf) synthesized...... in one or multiple stars and added to the protosolar molecular cloud before or during its collapse. Understanding how and when short-lived radioisotopes were added to the Solar System is necessary to assess their validity as chronometers and constrain the birthplace of the Sun. Whereas most CAIs...

    Ubatuba, tiene uma comunidad de pesca artesanal que es también remanesciente de um “quilombo”. Después de la apertura de rodovias permitiendo acceso al litoral norte de São Paulo, em los años setenta, la comunidade sufrió muchas pressiones de la especulación inmobiliaria para su desahucio o transferência, por causa de la belleza del lugar y sus possibilidades de uso turístico. Mas ella obtuvo el reconocimiento de su propriedade territorial, como “tierra de quilombo”, y hoy busca mantener su identidade y su cultura material. Una parte importante de esa cultura es su culinaria de peces, investigada por el A. en entrevistas abiertas com antiguos moradores de Caçandoca. Y hoy, proyectos comunitários y de gobierno ofrecen alternativas de aprovechamiento de esa cocina tradicional en uma actividad de turismo sustentable.

    1998-01-01

    Type B calcium-aluminum-rich inclusions (CAIs) can be thought of as a type of chondrule despite obvious differences in size, composition, and texture. Nevertheless, igneous CAIs likely experienced similar thermal histories. A major constraint on the thermal history of chondrules is that they have been recycled, mainly supported by the presence relict grains. Although well known that igneous CAIs experienced at least two melting events (counting Wark-Lovering rims), the identification of re...

    Full Text Available Con este artículo se pretende reflexionar sobre la manera en que los sujetos pertenecientes a una asociación, colectivo o red, re-significan, elaboran y piensan las diferentes emociones después de haber vivenciado como víctimas directas o indirectas el conflicto armado interno en Colombia (CAI. Esta reflexión se basará en un concepto denominado grupalidad que sana; el cual, se construyó pensando en la posible sanación psíquica que estos grupos pueden generar a través del acompañamiento del otro, creando iniciativas sociales de paz. El concepto de la grupalidad que sana, surge de realizar un dialogo entre la psicología social y psicología clínica desde una perspectiva psicoanalítica; donde se indagan diferentes antecedentes y postulados de distintos autores interesados en estudiar, conocer y comprender el funcionamiento de los grupos y de la grupalidad. Entendiéndose grupalidad según Kesselman (2008 desde una concepción de cuerpo y espacio que tiene que ver con comprender lo social más allá del lugar o paredes donde se trabaja con un grupo, es asimilar eso social y clínico como aquello que transita entre lo de adentro y lo de afuera. Para finalizar se rescata la importancia de la intersubjetividad y los vínculos que se gestan en el grupo para generar esa Grupalidad que sana.

    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.

    Refractory inclusions [calcium–aluminum-rich inclusions, (CAIs)] represent the oldest Solar System solids and provide information regarding the formation of the Sun and its protoplanetary disk. CAIs contain evidence of now extinct short-lived radioisotopes (e.g., 26Al, 41Ca, and 182Hf) synthesized...... in one or multiple stars and added to the protosolar molecular cloud before or during its collapse. Understanding how and when short-lived radioisotopes were added to the Solar System is necessary to assess their validity as chronometers and constrain the birthplace of the Sun.

    2014-02-01

    Quorum sensing (QS) is a process of bacterial cell-cell communication that relies on the production, detection and population-wide response to extracellular signal molecules called autoinducers. The QS system commonly found in vibrios and photobacteria consists of the CqsA synthase/CqsS receptor pair. Vibrio cholerae CqsA/S synthesizes and detects (S)-3-hydroxytridecan-4-one (C10-CAI-1), whereas Vibrio harveyi produces and detects a distinct but similar molecule, (Z)-3-aminoundec-2-en-4-one (Ea-C8-CAI-1). To understand the signalling properties of the larger family of CqsA-CqsS pairs, here, we characterize the Photobacterium angustum CqsA/S system. Many photobacterial cqsA genes harbour a conserved frameshift mutation that abolishes CAI-1 production. By contrast, their cqsS genes are intact. Correcting the P. angustum cqsA reading frame restores production of a mixture of CAI-1 moieties, including C8-CAI-1, C10-CAI-1, Ea-C8-CAI-1 and Ea-C10-CAI-1. This signal production profile matches the P. angustum CqsS receptor ligand-detection capability. The receptor exhibits a preference for molecules with 10-carbon tails, and the CqsS Ser(168) residue governs this preference. P. angustum can overcome the cqsA frameshift to produce CAI-1 under particular limiting growth conditions presumably through a ribosome slippage mechanism. Thus, we propose that P. angustum uses CAI-1 signalling for adaptation to stressful environments.

    We evaluate initial (Al-26/Al-27)(sub I), (Mn-53/Mn-55)(sub I), (Hf-182/Hf-180)(sub I), and Pb-207/Pb-206 ages for igneous differentiated meteorites and chondrules from ordinary chondrites for consistency with radioactive decay of the parent nuclides within a common, closed isotopic system, i.e., the early solar nebula. We find that the relative abundances of Al-26, Mn-53, and Hf-182, here denoted by I(Al)(sub CAI, I(Mn)(sub CAI) and I(Hf)(sub CAI), are consistent with decay from common initial values for the bulk solar system. I(Mn)(sub CAI) and I(Hf)(sub CAI) = 9.1+/-1.7 x 10(exp -6) and 1.06+/-0.09 x 10(exp -6) respectively, correspond to the canonical value of I(Al)(sub CAI) = 5.1 x 10(exp -5). I(Hf)(sub CAI) thus determined is consistent with I(Hf)(sub CAI) = 1.003+/-0.045 x 10(exp -6) directly determined in separate work. I(Mn)(sub CAI) is within error of the lowest value directly determined for CAI. We suggest that erratically higher values directly determined for CAI in carbonaceous chondrites reflect proton irradiation of unaccreted CAIs by the early Sun after other asteroids destined for melting by Al-26 decay had already accreted. The Mn-53 incorporated within such asteroids would have been shielded from further "local" spallogenic contributions. The relative abundances of the short-lived nuclides are less consistent with the Pb-207/Pb-206 ages of the corresponding materials with the best consistency being obtained between (Hf-182/Hf-180)(sub I) and Pb-207/Pb-206 ages of angrites. (Hf-182/Hf-180)(sub I) decreases with decreasing Pb-207/Pb-206 ages at the rate expected from the 8.90+/-0.09 Ma half-life of Hf-182. However, the model "CAI age" thus determined, T(sub CAI,Mn-W) = 4568.6+/-0.7 Ma, is older than the commonly accepted directly measured value T(sub CAI) = 4567.l+/-0.2 Ma. I(Al)(sub I), and (Mn-53/Mn-55)(sub I) are less consistent with Pb-207/Pb-206 ages, but determine T(sub CAI, Mn-Cr) = 4568.3+/-0.5 Ma relative to I(AI)(sub CAI)= 5.1 x 10(exp -5

    New Visean formations and biozones of foraminifera were defined on the Bouqachmir map. The new biozonation concerns the Moroccan biozone, Cfm1, which is subdivided into two subzones, Cfm1a and Cfm1b. This map exhibited, from north-west to south-east, the Tilouine, Bouqachmir-Tougouroulmès and Fourhal turbiditic basins. The first one, from Tournaisian to Late Visean, was the equivalent of the Sidi Bettache basin, located westwards. The second extended the Tilouine basin eastwards during the Visean. The third was a basin from Visean to Westphalian. They were separated by the Zaer-Oulmes and El Hammam horsts, else emerged or immersed, bordered by faults and with materials feeding chaotic deposits.

Ahora, en la edad del universalismo, por política se entiende la administración de las necesidades. ¿Cuál es el papel de la Masonería ante el hombre secularizado? A la Masonería se le han atribuido objetivos partidistas: la lucha contra el poder del clero y las doctrinas religiosas, contra la monarquía (pero esto no es válido para las organizaciones masónicas de Gran Bretaña, Países Bajos, Bélgica, Grecia y, en muchos épocas, también para Italia, España, incluso Francia, donde la Masonería fue borbónica y bonapartista, el militarismo (aunque muchos oficiales y suboficiales fueron masones… La comprobación de la autenticidad de los objetivos de las organizaciones masónicas se puede llevar a cabo analizando si algunos masones famosos eran sólo famosos o eran además masones.

    We report both oxygen- and magnesium-isotope compositions measured in situ using a Cameca ims-1280 ion microprobe in 20 of 166 CAIs identified in 47 polished sections of 15 CR2 (Renazzo-type) carbonaceous chondrites. Two additional CAIs were measured for oxygen isotopes only. Most CR2 CAIs are mineralogically pristine; only few contain secondary phyllosilicates, sodalite, and carbonates - most likely products of aqueous alteration on the CR2 chondrite parent asteroid. Spinel, hibonite, grossite, anorthite, and melilite in 18 CAIs have 16O-rich (Δ 17O = -23.3 ± 1.9‰, 2 σ error) compositions and show no evidence for postcrystallization isotopic exchange commonly observed in CAIs from metamorphosed CV carbonaceous chondrites. The inferred initial 26Al/ 27Al ratios, ( 26Al/ 27Al) 0, in 15 of 16 16O-rich CAIs measured are consistent with the canonical value of (4.5-5) × 10 -5 and a short duration (oxygen- and magnesium-isotope compositions (˜11 and 23‰/amu, respectively), a deficit of 26Mg, and a relatively low ( 26Al/ 27Al) 0 = (2.0 ± 1.7) × 10 -5. This could be the first FUN ( Fractionation and Unidentified Nuclear effects) CAI found in CR2 chondrites. Because this inclusion is slightly 16O-depleted compared to most CR2 CAIs and has lower than the canonical ( 26Al/ 27Al) 0, it may have experienced multistage formation from precursors with nonsolar magnesium-isotope composition and recorded evolution of oxygen-isotope composition in the early solar nebula over 0.9+2.2-0.7 My. Eight of the 166 CR2 CAIs identified are associated with chondrule materials, indicating that they experienced late-stage, incomplete melting during chondrule formation. Three of these CAIs show large variations in oxygen-isotope compositions (Δ 17O ranges from -23.5‰ to -1.7‰), suggesting dilution by 16O-depleted chondrule material and possibly exchange with an 16O-poor (Δ 17O > -5‰) nebular gas. The low inferred ( 26Al/ 27Al) 0 ratios of these CAIs (2 My after crystallization

    To understand why subjects with chronic ankle instability (CAI) have frequent sprains, one must study the preparation/reactions of these subjects to situations related to ankle inversion in real life. In the present pilot study, we examined whether subjects with CAI altered their neuromuscular control and reflex responses during and after ankle perturbations in landing. EMG signals were collected from the tibialis anterior (TA), peroneus longus (PL), medial gastrocnemius (MG), and gluteus medius (GLM) of both legs in 9 subjects with CAI and 9 subjects with intact ankles (control). A trapdoor was used to produce an ankle inversion of 25° with the left leg (control) or the affected leg (CAI) in 0%, 50% or 100% of the landing trials. As compared to controls, subjects with CAI had increased proactive activity in the contralateral side prior to touchdown during landing trials with 50% (PL) and 100% (PL and MG) chance of inversion (all, p proactive control on the contralateral side could be part of a strategy to smooth the impact of landing on the affected side in subjects with CAI. Following touchdown, the CAI group showed decreased ipsilateral short latency reflex (SLR) responses in all test conditions both in distal (PL and MG) and in proximal muscles (GLM) on the affected side (all, p strategies from controls while landing.

    In a process known as quorum sensing, bacteria use chemicals called autoinducers for cell-cell communication. Population-wide detection of autoinducers enables bacteria to orchestrate collective behaviors. In the animal kingdom detection of chemicals is vital for success in locating food, finding hosts, and avoiding predators. This behavior, termed chemotaxis, is especially well studied in the nematode Caenorhabditis elegans. Here we demonstrate that the Vibrio cholerae autoinducer (S)-3-hydroxytridecan-4-one, termed CAI-1, influences chemotaxis in C. elegans. C. elegans prefers V. cholerae that produces CAI-1 over a V. cholerae mutant defective for CAI-1 production. The position of the CAI-1 ketone moiety is the key feature driving CAI-1-directed nematode behavior. CAI-1 is detected by the C. elegans amphid sensory neuron AWC(ON). Laser ablation of the AWC(ON) cell, but not other amphid sensory neurons, abolished chemoattraction to CAI-1. These analyses define the structural features of a bacterial-produced signal and the nematode chemosensory neuron that permit cross-kingdom interaction.

    Refractory inclusions [calcium-aluminum-rich inclusions, (CAIs)] represent the oldest Solar System solids and provide information regarding the formation of the Sun and its protoplanetary disk. CAIs contain evidence of now extinct short-lived radioisotopes (e.g., (26)Al, (41)Ca, and (182)Hf) synthesized in one or multiple stars and added to the protosolar molecular cloud before or during its collapse. Understanding how and when short-lived radioisotopes were added to the Solar System is necessary to assess their validity as chronometers and constrain the birthplace of the Sun. Whereas most CAIs formed with the canonical abundance of (26)Al corresponding to (26)Al/(27)Al of ∼5 × 10(-5), rare CAIs with fractionation and unidentified nuclear isotope effects (FUN CAIs) record nucleosynthetic isotopic heterogeneity and (26)Al/(27)Al of Solar System, including the origin of short-lived radioisotopes. However, their chronology is unknown. Using the (182)Hf-(182)W chronometer, we show that a FUN CAI recording a condensation origin from a solar gas formed coevally with canonical CAIs, but with (26)Al/(27)Al of ∼3 × 10(-6). The decoupling between (182)Hf and (26)Al requires distinct stellar origins: steady-state galactic stellar nucleosynthesis for (182)Hf and late-stage contamination of the protosolar molecular cloud by a massive star(s) for (26)Al. Admixing of stellar-derived (26)Al to the protoplanetary disk occurred during the epoch of CAI formation and, therefore, the (26)Al-(26)Mg systematics of CAIs cannot be used to define their formation interval. In contrast, our results support (182)Hf homogeneity and chronological significance of the (182)Hf-(182)W clock.

  18. Spatiotemporal characteristics of calcium dynamics in astrocytes

    2009-09-01

    Although Cai2+ waves in networks of astrocytes in vivo are well documented, propagation in vivo is much more complex than in culture, and there is no consensus concerning the dominant roles of intercellular and extracellular messengers [inositol 1,4,5-trisphosphate (IP3) and adenosine-5'-triphosphate (ATP)] that mediate Cai2+ waves. Moreover, to date only simplified models that take very little account of the geometrical struture of the networks have been studied. Our aim in this paper is to develop a mathematical model based on realistic cellular morphology and network connectivity, and a computational framework for simulating the model, in order to address these issues. In the model, Cai2+ wave propagation through a network of astrocytes is driven by IP3 diffusion between cells and ATP transport in the extracellular space. Numerical simulations of the model show that different kinetic and geometric assumptions give rise to differences in Cai2+ wave propagation patterns, as characterized by the velocity, propagation distance, time delay in propagation from one cell to another, and the evolution of Ca2+ response patterns. The temporal Cai2+ response patterns in cells are different from one cell to another, and the Cai2+ response patterns evolve from one type to another as a Cai2+ wave propagates. In addition, the spatial patterns of Cai2+ wave propagation depend on whether IP3, ATP, or both are mediating messengers. Finally, two different geometries that reflect the in vivo and in vitro configuration of astrocytic networks also yield distinct intracellular and extracellular kinetic patterns. The simulation results as well as the linear stability analysis of the model lead to the conclusion that Cai2+ waves in astrocyte networks are probably mediated by both intercellular IP3 transport and nonregenerative (only the glutamate-stimulated cell releases ATP) or partially regenerative extracellular ATP signaling.

    Ca-A1 rich refractory mineral inclusions (CAIs) found at 1-6% mass fraction in primitive chondrites appear to be 1-3 million years older than the dominant (chondrule) components which were accreted into the same parent bodies. A prevalent concern is that it is difficult to retain CAIs for this long against gas-drag-induced radial drift into the sun. We reassess the situation in terms of a hot inner (turbulent) nebula context for CAI formation, using analytical models of nebula evolution and particle diffusion. We show that outward radial diffusion in a weakly turbulent nebula can overwhelm inward drift, and prevent significant numbers of CAI-size particles from being lost into the sun for times on the order of 10(exp 6) years. CAIs can form early, when the inner nebula was hot, and persist in sufficient abundance to be incorporated into primitive planetesimals at a much later time. Small (less than or approximately 0.1 mm diameter) CAIs persist for longer times than large (greater than or approximately 5mm diameter ones. To obtain a quantitative match to the observed volume fractions of CAIs in chondrites, another process must be allowed for: a substantial enhancement of the inner hot nebula in silicate-forming material, which we suggest was caused by rapid inward drift of meter-sized objects. This early in nebula history, the drifting rubble would have a carbon content probably an order of magnitude larger than even the most primitive (CI) carbonaceous chondrites. Abundant carbon in the evaporating material would help keep the nebula oxygen fugacity low, plausibly solar; as inferred for the formation environment of CAIs. The associated production of a larger than canonical amount of CO2 might also play a role in mass-independent fractionation of oxygen isotopes, leaving the gas rich in O-16 as inferred from CAIs and other high temperature condensates.

  1. Carbachol increases basolateral K+ conductance in T84 cells. Simultaneous measurements of cell [Ca] and gK explore calcium's role.

    1990-12-01

    To explore the role of calcium in mediating the action of carbachol in chloride-secreting epithelia, we simultaneously measured intracellular free [Ca] ([Ca]i) and the potassium conductance (gK) of the basolateral membrane in T84 cells grown on collagen-coated filters. [Ca]i was measured with fura-2 and fluorescence microscopy and expressed as a relative value ([Ca]'i) normalized to control. To assess changes in basolateral gK, we measured the short circuit current (Isc) in the presence of luminal amphotericin and a transepithelial mucosa-to-serosa K+ gradient (Germann, W. J., M. E. Lowy, S. A. Ernst, and D. C. Dawson. 1986. J. Gen. Physiol. 88:237-251). Treatment of the monolayers with carbachol resulted in a parallel increase and then decrease in [Ca]'i and gK. The carbachol-induced changes in gK appeared to be dependent on the increase in [Ca]i because stimulation of gK was significantly diminished when the hormone-induced increase in [Ca]'i was blunted, either by loading the cells with BAPTA or by reducing the extracellular [Ca]. The carbachol-stimulated increase in gK appeared to be the direct result of the increase in steady-state [Ca]'i. The changes in gK and [Ca]'i after stimulation with carbachol were correlated and ionomycin also increased gK and [Ca]'i in a parallel manner. The carbachol-induced delta gK per delta[Ca]'i, however, was greater than that after ionomycin. Because ionomycin and carbachol appear to open the same channel, a conclusion based on inhibitor and selectivity experiments, carbachol may have a second action that amplifies the effect of calcium on gK.

    This article has provided the principles of CAI development, marketing strategies, information on getting started with CAI, and how to approach publisher vendors. Guidelines for software development proposals have been synthesized from major software publishers in nursing. There is a great demand for courseware that teaches critical thinking skills, problem solving, application, and analysis. Tutorials and simulations are much needed. Computer-assisted testing courseware will also be highly used by teachers at all levels in the future. Opportunity awaits the CAI author in the publishing arena! PMID:3903670

    We discuss the standardization of input formats in CAI program. In CAI input behavior is a bottle neck for students and in order to break through this, CAI program must be checked by following points, (1) adjustment of hardware environment (2) one character input without hitting carriage return key (3) guide message with blinking : ' hit the return key at the end of input !' (4) controlled input guide message as prompt (5) correction of input error (6) undo-passing of input command, if necess...

  7. Depolarization by K+ and glutamate activates different neurotransmitter release mechanisms in GABAergic neurons: vesicular versus non-vesicular release of GABA

    DEFF Research Database (Denmark)

    Belhage, B; Hansen, Gert Helge; Schousboe, A

    1993-01-01

    Neurotransmitter release and changes in the concentration of intracellular free calcium ([Ca++]i) were studied in cultured GABAergic cerebral cortical neurons, from mice, upon depolarization with either an unphysiologically high potassium concentration (55 mM) or the physiological excitatory...... neurotransmitter glutamate (100 microM). Both depolarizing stimuli exerted prompt increases in the release of preloaded [3H]GABA as well as in [Ca++]i. However, the basic properties of transmitter release and the increase in [Ca++]i under a variety of conditions were different during stimulation with K+ or...... in nature whereas that induced by the neurotransmitter glutamate is not....

    Calcium-aluminum-rich refractory inclusions (CAIs) are thought to be the first-formed solids in the Solar protoplanetary disk and can provide information about the earliest Solar System processes (e.g., [1]). A hibonite-perovskitebearing CAI from the Allende CV3 chondrite (SHAL, [2]) contains a single of 500 micrometers hibonite grain and coarse-grained perovskite. The mineralogy and oxygen isotopic composition of this CAI shows similarities with FUN inclusions, especially HAL [2]. Here we present trace element abundances in SHAL.

    1990-01-01

    To explore the role of calcium in mediating the action of carbachol in chloride-secreting epithelia, we simultaneously measured intracellular free [Ca] ([Ca]i) and the potassium conductance (gK) of the basolateral membrane in T84 cells grown on collagen-coated filters. [Ca]i was measured with fura-2 and fluorescence microscopy and expressed as a relative value ([Ca]'i) normalized to control. To assess changes in basolateral gK, we measured the short circuit current (Isc) in the presence of lu...

  19. A refractory inclusion in the Kaba CV3 chondrite - Some implications for the origin of spinel-rich objects in chondrites

    Science.gov (United States)

    Fegley, B.; Post, J. E.

    1985-11-01

    The first detailed petrographic and mineralogical study of a Ca, Al-rich inclusion (CAI) from the Kaba CV3 chondrite is reported. This 'fine-grained' CAI contains abundant small, rounded, rimmed, spinel-rich objects which have important features in common with the spinel-rich objects in other carbonaceous and ordinary chondrites. These nodules are interpreted as fractionated distillation residues of primitive dust. However, the available data do not unambiguously rule out a condensation origin for at least some of these objects. Finally, the preservation of distinct diopside-hedenbergite rims on the spinel-rich bodies and the small grain size of many minerals in the CAI matrix material both suggest that the CAI accreted cool and had a relatively cool thermal history in the Kaba parent body.
