    In a continuation of my search for an understanding of sunlight's relationship to the health of the human organism, I created the installation A Journey Through Bui-Bui; Lifting the Purdah of Mal-Illumination. It was exhibited in 1999 at The Museum of Fine Arts, Santa Fe, New Mexico. The entire work pivots around the image of the veil worn by Muslim women, as both content and metaphor related to the issue of the absence or presence of light in the physical body. The following paper will discuss the development of concepts and the technical progression of this recently completed large-scale mixed media work. This three-roomed installation integrated life casts of the human figure covered in veils, various sculptural elements, fiber optics, and dichromated gelatin (DCG) holograms. The DCG holographic glass objects were produced with an array of glass sculpting tools. I will also briefly discuss current work evolving out of this installation, which further explored the sculptural possibilities of glass and the coating and recording of DCG on curved surfaces.

  2. Culture, power and identity The case of Ang Hien Hoo, Malang

    2017-05-01

    Full Text Available This paper discusses the intricate relations between culture and identity in a web of larger power structures of politics and the market by looking at the ways in which the Indonesian Chinese attach themselves to a local performing arts tradition. The paper focuses on the history of the wayang orang amateur club called Ang Hien Hoo in Malang, East Java, which emerged from a Chinese diaspora burial association, to attract national limelight in the 1950s and 1960s. In this paper, I see this amateur club as a site, not only for cultural assimilation, but also as a meeting space for the diverse migrant Chinese population residing at a host country. The space is used to negotiate their position as citizens responsible to promote and to become patrons of local traditional performing arts. The paper examines how this amateur club was swept by the Cold War politics and national political turmoil of 1965, and how it fought to survive under the pressures of the global capitalist era. What emerges from the findings is the contradictory fact that the identification of the Chinese with the Javanese traditional performing arts is affirmed precisely as it is marked by Chineseness. Thus, despite the cultural blending, the Chinese Indonesian’s patronage of local traditional art continuously reproduces the double bind of making home in the culture not seen as their own.

    Full Text Available Abstract Background The majority of Cameroonians depend on traditional medicines for their health care needs and about seven per cent of the average household health budget is spent on traditional medicines irrespective of their incomes. The aim of the present study was to determine the oral care knowledge and practices of Traditional Healers (TH on oral health delivery in the urban and rural areas of Bui Division of Cameroon and the objectives to determine the cost of treatment and reasons why people visit TH. Methods The present study was cross sectional and utilized semi-structured questionnaires to collect data. Results The sample consisted of 21 TH and 52 clients of TH. Sixty two percent of the TH's were above 40 years and 90% male. The mean age was 46 years (range 20-77 years. Twenty four percent of the TH practiced as herbalists and the remainder both divination and herbalism. Sixty seven percent of people in the Bui Division, who patronize TH for their oral health needs, fall within the 20-40 year age group. There is little collaboration between the oral health workers and TH and only 6% of all patients seen by TH are referred to the dentist. Socio-cultural and economic factors affect the oral health care seeking behavior of patients in this area and only 6.5% of patients visit dental clinics. Reasons for not attending dental clinics included high cost, poor accessibility, superstition and fear. TH's are not experienced in the treatment of pulpitis - the majority of patients who presented with toothache had temporary or no relief, but despite this 67% reported being satisfied with their treatment. Sixty nine percent of the patients visited TH because of low cost - the average cost of treatment with TH (approximately $5 is very low, as compared to conventional treatment ($50. Conclusions Traditional healers are willing to co-operate with oral health workers in improving oral health. Since they have a vital role to play in health care

    2015-11-01

    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

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

    Energy Technology Data Exchange (ETDEWEB)

    Mellors, R J

    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.

    2016-04-01

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

    Howell, B J

    1969-03-01

    A four-lens corrector system to remove residual aberrations in a Ritchey-Chrétien telescope was selected as the means of studying the relative effectiveness of two design methods: a ray deviation error function and third order aberration theory. At several stages in the design, very significant improvements were made by switching from ray deviation results to aberration theory and then back to ray deviation design. The goal, a 300-cm focal length, f/10 diffraction-limited 1.2 degrees flat field telescope for white light, was achieved. Lens data and system performance, including computed spot diagrams, are given for eight versions.

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

    Shamshy, S.; Pavlis, G. L.

    2003-12-01

    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

    Full Text Available Phytoplankton constitutes the primary producers of aquatic ecosystems and represents the food chain base that supports the commercial fisheries of most water bodies. Nowadays, there is lack of information on phytoplankton assemblages of most reservoirs in Africa. To contribute with this knowledge, this study was carried out to determine the density and diversity of seasonal variations of phytoplankton species in the Bui dam area of the Black Volta, during the pre- (2011 and post-impoundment (2012 periods. For this, a three-level stratified random sampling approach was adopted for 22 months. Phytoplankton samples were obtained by towing a 0.5m diameter phytoplankton net (35μm mesh size and 0.25m² mouth surface area from a non-motorized canoe through a distance of about 100m against the current from downstream to upstream of the river. In 2011, 35 species of phytoplankton belonging to four classes, Bacillariophyceae (7.6%, Chlorophyceae (43%, Cyanophyceae (48.6% and Euglenophyceae (0.8% were identified. In the 2012 sampling, 18 species belonging to three classes, Bacillariophyceae (2.2%, Chlorophyceae (26.1% and Cyanophyceae (71.7% were observed. A total of 17 species of phytoplankton, including Gyrosigma sp., Surirella sp., Carteria sp., Chlosterium sp., Chlorogonium sp., Coelastrum sp., Cosmarium sp., Volvox sp., Chroococcus sp., Coelosphaerium sp., Rivularia sp. and Spirulina sp., were absent during the late post-impoundment period. Mean monthly total phytoplankton abundance decreased from June (7 384 cells/m³ to August (106cells/m³ in 2011. In 2012 however, mean total phytoplankton decreased from February (1 237cells/m³ to August (4cells/m³. The results also showed that variations occurred between seasons among some phytoplankton groups. The dry and pre-wet seasons had significantly (p<0.05 higher mean phytoplankton abundance than the wet season during the 22 months of sampling period. The biotic indices of Shannon-Wiener (H¹ were

Para poder sustentar esto se han creado metodologías como las técnicas de afloramiento de significado y las técnicas proyectivas entre otras. Pero, el nuevo problema que surge de esta conceptualización teórica es si vamos a poner al significado en la base del plan de marketing, la pregunta es ¿cuántos significados se deben determinar? Por lo que sabemos cada cultura tiene sus propias significaciones y los significados también cambian con el tiempo incluso lo hacen contextualmente. Lo cual hace aún más complejo el dilema presentado como título de este artículo.

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

    The Pamir Salient and Southwestern Tien Shan belong to two different systems, which collided due to the continuous northward drift of the Indian Plate during the Cenozoic, resulting in a shortening of 300 km. The uplift history and kinematic evolution of the Pamir-Southwestern Tien Shan remain unclear. In this study, we chose the 2025 m-thick Pakabulake formation in the East Wuqia section, at the southern-most margin of the Southwestern Tien Shan system, to obtain a high-resolution magnetostratigraphic record spanning 16.61 Ma to 9.78 Ma. Based on its high sedimentation rate, stable ca. E-W paleocurrents and stable magnetic susceptibility values, the nearby Southwestern Tien Shan was inferred to have undergone stable uplift during this period of sedimentation. Combining our results with the previous low-temperature thermochronology, magnetostratigraphy and re-calculated block rotations, we conclude that four episodic uplift events occurred in the Pamir-Southwestern Tien Shan during the Cenozoic, at times of 50-40 Ma, 35-16 Ma, 11-7 Ma and < 5 Ma, and that the first episodic uplift only occurred in the Pamir Salient. In addition, the Pamir Salient underwent a tectonic transformation from entire- to a half-oroclinal bending rotation during the Miocene, caused by activity along the Karakorum Fault and Kashgar-Yecheng Transfer System.

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

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

    Kulikova, G.; Krueger, F.

    2013-12-01

    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

    Full Text Available This study aims to enhance the mapping of forecast for water quality assessment in Mekong Delta provinces. The data from 32 sites from main rivers and canals in an area of around 2,482 km2 in Tien Giang Province, Vietnam, were used for calculation and mapping. The ArcGIS 9.3 software, Inverse Distance Weighting (IDW interpolation method, hydrologic data, and water quality parameters in March (2010-2014 were applied to build the maps showing 2020 water quality predictions for main rivers and canals in Tien Giang Province. The estimation was based on the Water Quality Index (WQI with 6 parameters such as pH, total suspended solid (TSS, dissolved oxygen (DO, biochemical oxygen demand (BOD, total nitrogen (T_N, and coliform. The results showed that water quality in the studied area in dry season will not be improved by the year 2020. The finding could be a scientific reference for the selection of effective approaches to improve water quality in main rivers and canals in Tien Giang Province.

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

    The prevalence of overweight and obesity in children has risen nationally in recent decades, and is exceptionally high in low-income communities of color such as South Los Angeles CA. Independently owned restaurants participating in the Salud Tiene Sabor program at ethnic foods marketplace Mercado La Paloma in South Los Angeles are responding to the childhood obesity crisis by posting calories for menu items and providing nutrition information to patrons. To evaluate whether menu labeling and nutrition information at point of purchase have an influence on availability of healthy food options, patron awareness of calorie information, and restaurant owners' support of the program. A case-study design using mixed methods included restaurant owner and stakeholder interviews, patron surveys, and environmental assessments. Data were collected using originally designed tools, and analyzed in 2009-2011. Healthy eating options were available at the Mercado La Paloma; restaurant owners and the larger community supported the Salud Tiene Sabor program; 33% of patrons reported calorie information-influenced purchase decisions. Owners of independent restaurants have an important role in improving access to healthy foods in low-income, Latino communities. Copyright © 2013 American Journal of Preventive Medicine.

    Nelson, Michael R.; Mccaffrey, Robert; Molnar, Peter

    1987-01-01

    The style and the distribution of faulting occurring today in the Tien Shan region were studied, by digitizing long-period World-Wide Standard Seismograph Network P and SH waveforms of 11 of the largest Tien Shan earthquakes between 1965 and 1982 and then using a least squares inversion routine to constrain their fault plane solutions and depths. The results of the examination indicate that north-south shortening is presently occurring in the Tien Shan, with the formation of basement uplifts flanked by moderately dipping thrust faults. The present-day tectonics of the Tien Shan seem to be analogous to those of the Rocky Mountains in Colorado, Wyoming, and Utah during the Laramide orogeny in Late Cretaceous and Early Tertiary time.

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

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

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

    2013-12-01

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

    High mountain areas provide water resources for a large share of the world's population. The ongoing deglaciation of these areas is resulting in great instability of mountainous headwater regions, which could significantly affect water supply and intensify dangerous hydrological processes. The hydrological processes in mountains are still poorly understood due to the complexity of the natural conditions, great spatial variation and a lack of observation. A knowledge of flow-forming processes in alpine areas is essential to predict future possible trends in hydrological conditions and to calculate river runoff characteristics. The goal of this study is to gain detailed field data on various components of natural hydrological processes in the alpine areas of the North Caucasus and Central Tien Shan, and to investigate the possibility that the isotopic method can reveal important regularities of river flow formation in these regions. The study is based on field observations in representative alpine river basins in the North Caucasus (the Dzhankuat river basin) and the Central Tien Shan (the Chon-Kyzyl-Suu river basin) during 2013-2015. A mixing-model approach was used to conduct river hydrograph separation. Isotope methods were used to estimate the contribution of different nourishment sources in total runoff and its regime. d18O, dD and mineralization were used as indicators. Two equation systems for the study sites were derived: in terms of water routing and runoff genesis. The Dzhankuat and Chon-Kyzyl-Suu river hydrographs were separated into 4 components: liquid precipitation/meltwaters, surface routed/subsurface routed waters.

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

    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

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

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

    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 monitoring of glacier mass balance in remote regions is important to understand the response of glaciers to climate change. The coverage of monitored glaciers in Central Asia has been very limited for the past 15 years; however the necessity of enhanced understanding regarding glacier dynamics and long term evolution in this particular region is crucial. Moisture availability importantly determines glacier response. Glaciers located in the Northern Tien Shan and Pamir Mountains are likely not to be directly influenced by monsoon such as most monitored Peri-Himalayan glaciers. However, not only scientific reasons make glacier monitoring to be of great relevance, also the link to political and socio-economic constraints on water scarcity carries high importance. First steps towards the establishment of a new glacier monitoring network were performed in 2010/2011 and since then modernization and extension of the monitoring strategies are continuously aspired. Close cooperation of international and local scientists build the basis of the program. Today four glaciers located in the Kyrgyz Tien Shan (Golubin Glacier, Suek Zapadniy Glacier, Glacier No. 354) and the North-Western Pamir (Abramov Glacier) are regularly monitored. The network is planned to be extended in the next years to cover selected glaciers in Uzbekistan and Tajikistan. Further, we intend to develop new approaches to remotely monitor sub-seasonal glacier mass balance at a regional scale. In-situ mass balance measurements are taken at all four glaciers continuously in late summer. Automatic weather stations installed at Abramov Glacier in 2011 and at Golubin Glacier in 2013 deliver daily meteorological data allowing the application of a simple mass balance model driven with local precipitation and temperature data. Model calibration is performed using glaciological measurements and results are validated with snowline observations based on remote imagery. Automatic cameras at Abramov Glacier take

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

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

    In 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.

    Full Text Available Landslides triggered by strong earthquakes often caused most of the global damage and most of all casualties related to the events, such as shown by the M = 7.7 Peru earthquake in 1970, by the M = 7.6 El Salvador earthquake in 2001 or by the M = 7.4 Khait (Tajikistan earthquake in 1949. The obvious impact of a landslide on the population is directly related to its movement. Yet, prediction of future failure potential and hence future risk to population is necessary in order to avoid further catastrophes and involves the analyses of the origin of seismic instability. The seismic landslide potential is mainly determined by the interaction between the regional seismic hazard and local geological conditions. At a local scale, seismic factors interfering with geological conditions can produce site-specific ground motions. The influence of such Site Effects on instability is the principal topic of this paper, which is divided into two parts, A and B. The present Part A is concerned with the correlation of field data with observed instability phenomena. Field data were obtained on mainly three landslide sites in the Northern Tien Shan Mountains in Kyrgyzstan, Central Asia. Geophysical prospecting, earthquake recordings, geological observation, trenching and geotechnical tests were the main investigation tools. The collected information gives an insight in the geological background of the slope failure and allows us to roughly infer failure mechanisms from field evidence. A detailed analysis of the susceptibility of a mechanism to specific geological conditions will be shown in Part B.

    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.

    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.

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

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

    We present results of the study of data of the monitoring of high-energy and thermal neutrons at Tien Shan at different stages of thunderstorm activity. The data of the neutron monitoring were used taking into account the barometric effect. The intensity of the neutron component of cosmic rays is recorded in seven energy ranges. The electric field has values of ~ 100 V/m under fair weather conditions. Standard deviation of minute values of the neutron monitor data at the high altitude station does not exceed 0.5-0.6 %. Found that the standard deviation of the data during thunderstorms always exceeds these values. We selected events during the passage of thunderstorm clouds over the high altitude station without lightning discharges or with a small number of them. It was found that the particle rate of the neutron monitor changes in antiphase with the electric field changes. Atmospheric electric field of positive polarity decreases the count rate of the neutron monitor, and negative polarity - increases. Change of the count rate occurs at values of electric field ≥ 10-15 kV/m and reaches 2 %. The neutron monitor at the high-altitude station has the ability to measure the energy of recorded particles through determination of their multiplicity. We experimentally established that the sensitivity of the detected particles to change in Ez increases with decreasing their energy. The upper energy threshold of sensitivity of neutrons to change electric field is ~10 GeV. The physical mechanism of effect is based on lead nucleus capture of soft negative muons with the subsequent generation of neutrons. It is known that 7% of the neutron monitor count rate caused by negative muons. Absence of this effect in thermal neutrons data confirms the conclusion since the main difference of the thermal neutrons detector from the neutron monitor is the absence of the lead. In the active phase of a thunderstorm in the formed thundercloud the picture of distribution of charges is

    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

    Tien-Hua-Hu Reservoir is currently under planning by the Water Resources Agency, Taiwan to meet the increasing water demands of central Taiwan arising from rapid growth of domestic water supply, and high-tech industrial parks. This study develops a simulation model for the ten-day period reservoir operation to calculate the ten-day water shortage index under varying rule curves. A genetic algorithm is coupled to the simulation model to find the optimal rule curves using the minimum ten-day water shortage index as an objective function. This study generates many sets of synthetic streamflows for risk, reliability, resiliency, and vulnerability analyses of reservoir operation. ARMA and disaggregation models are developed and applied to the synthetic streamflow generation. The optimal rule curves obtained from this study perform better in the ten-day shortage index when compared to the originally designed rule curves from a previous study. The optimal rule curves are also superior to the originally designed rule curves in terms of vulnerability. However, in terms of reliability and resiliency, the optimal rule curves are inferior to the those originally designed. Results from this study have provided in general a set of improved rule curves for operation of the Tien-Hua-Hu Reservoir. Furthermore, results from reliability, resiliency and vulnerability analyses offer much useful information for decision making in reservoir operation.

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

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

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

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

    The zones of the origin of seismic centers within highly seismic areas of the Pamirs and Tien Shan are established. The majority of catastrophic earthquakes coincide with them in this part of High Asia. Their establishment is based on the distribution of the most intensive epicenters and the maximal volumes of the seismic energy together with its calculation and forecasting of the possible manifestations of high seismicity. The investigation of the deep structure of these zones allows us to determine the connection of the seismicity with geophysical field anomalies and some factors of the deep and near surface lithosphere and crust structure, which influence the present-day geodynamics. The results of our research enable us to appreciate the level of the seismic danger in different parts of the region investigated.

    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.

  8. Glacier area and mass changes since 1964 in the Ala Archa Valley, Kyrgyz Ala-Too, northern Tien Shan

    Full Text Available Glaciers are an important source of fresh water for Central Asia as they release water during the summer months when precipitation is low and water demand highest. Many studies address glacier area changes but only changes in glacier mass can be directly linked to climate and runoff. Despite the importance, investigations of glacier mass changes have been restricted to only a few glaciers in the Tien Shan until now. Geodetic mass balance measurements are suitable to complement and extend existing in-situ measurements. In this study, both area and mass changes of the ~40 km² glacier ice in the Ala Archa Valley, Kyrgyz Tien Shan, were investigated using 1964 and 1971 stereo Corona, 2012 stereo ASTER, the SRTM digital terrain model and other optical data such as Landsat ETM+ or Rapid Eye. In addition, ice thickness was modeled taking the basal shear stress and the glacier surface topography into account. The results indicate an area loss of 18.3±5.0% from 1964 until 2010 with continuous shrinkage in all investigated periods. The glacier’s mass balance was −0.45±0.27 m w.e. a−1 for the period 1964–1999 and −0.42±0.66 m w.e. a−1 for 1999–2012. Golubin Glacier showed a possible slight mass gain for 1964– 1971 and a decelerated mass loss for the 1999–2012 period. This is in good agreement with existing in-situ measurements exiting from 1962 until 1994 and since 2010. The overall ice volume was estimated to be 1.56±0.47 km³ of ice in the year 2000. Hence, the entire ice would be lost by 2100 if the mass loss would continue at the same rate

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

    The Central Asian Orogenic Belt (CAOB) represents one of the largest Phanerozoic accretionary orogens in the world, pinched between North China - Tarim, Kazakhstan and the Siberian craton. It stretches from the Pamir in the southwest, over the Tien Shan, Junggar, Altai and Sayan mountain ranges to the Baikal rift in the northeast. The basement of the CAOB exists of various tectonic units that were assembled during several Paleozoic collision-accretion events. By the Permian, the accretionary tectonics in the CAOB culminated as all major composing units were joined. After final construction in the Late Paleozoic, the CAOB was subjected to several phases of Mesozoic deformation and was again reactivated in the Late Cenozoic as distant effect of the India-Eurasia collision. The Meso-Cenozoic reactivation episodes occurred in an intracontinental setting, related to tectonic far-field effects originating at the Eurasian margins. Subsequently intracontinental orogens, such as Tien Shan, were built superimposed on the inherited basement architecture and the erosion products of their exhuming mountain ranges accumulated in sedimentary basins. New sedimentological and detrital zircon U-Pb (LA-ICP-MS) results from several Jurassic to Paleogene sedimentary sections in Kyrgyzstan provide new insights in the Mesozoic - early Cenozoic geodynamic evolution and related basin-range interactions of the Kyrgyz Tien Shan. Studied sedimentary sections are located in the Fergana and Yarkand-Fergana basins to the west of the Talas-Fergana Fault (TFF) and in the Issyk-Kul and Ming-Kush-Kökömeren basins to the east of the TFF. The U-Pb ages of the post-Precambrian zircon grains found in 18 Jurassic to Paleogene sandstones, can be generally divided into four groups: Caledonian (470-390 Ma), Hercynian (315-260 Ma), Triassic (250-210 Ma) and Jurassic (190-160 Ma) ages. The differences in sedimentation pattern and detrital zircon U-Pb age components suggest that the TFF played an important

    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

    Full Text Available In this study, tree-ring width data of Schrenk spruce (Picea schrenkiana from the upper timberline of the Tien Shan (Kyrgyzstan were analyzed to investigate the effect of climate change. Growth–climate response analyses revealed that the tree rings of spruce at the upper timberline of the Tien Shan also can provide hydrometeorological (precipitation and streamflow signals. Tree-ring records from both Kyrgyzstan and Xinjiang exhibited similar tree-growth variability at both annual and decadal time scales during the common period 1457–2009. In Xinjiang and Kyrgyzstan, tree growth was reduced during the Little Ice Age (LIA; however, the timing and magnitude of LIA differ between the two regions. During 1470–1660, the two chronologies diverged, and this phenomenon is considered to be caused by a different response to the harsh climate of the LIA. In this study, the tree-ring width series from the upper tree line of the Tien Shan is negatively associated with temperature. As opposed to previous studies, the tree-ring width series from the upper timberline of the Tien Shan appears to respond well to hydrometeorological factors. Therefore, we highlight the need for more detailed ecophysiological response studies for spruce trees at the upper timberline of the Tien Shan, in particular, with regard to the role of water availability and temperature during the growth season.

    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.

    Using field surveys in 2013, 2014, and 2016 plus satellite data from the 1999-2015 period, we analyze the seasonal drainage cycle of supraglacial lakes on seven debris-covered glaciers in the central Tien Shan. We characterize this cycle by the number of lakes and their water levels. The cycle of the Southern Inylchek Glacier starts to increase in the beginning of April, reaches a maximum in May-June, and decreases sharply in June-July. The increase in April to June comes from an inflow of meltwater from snow and ice, and the subsequent decrease arises from a greater connectivity to the englacial drainage network. For the Southern Inylchek Glacier, 94% of the supraglacial lakes that exist and appear during 2013-2015 drain during all three years, indicating that most lakes could connect to the englacial drainage network for three years. Concerning the water level, lakes in close proximity and with the same base-level tend to synchronize their seasonal water levels through the englacial channels. Although the maximum water level of the three-year, field-measured lake is about the same from 2014 through 2016, the date of maximum water level varies between mid-May and mid-June. During this period, the lifetime and size of the supraglacial lakes are controlled by the timing of their connectivity to the englacial drainage network.

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

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

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

    We studied more than 80 lava flows from a ˜600-m-thick pile of Upper Devonian (Frasnian) basalts and andesites of the Aral Formation in the North Tien Shan (Kyrgyzstan, Central Asia). With the aid of stepwise thermal demagnetization, a high-temperature, dual-polarity component was reliably isolated from most flows. The primary origin of the high-temperature component is demonstrated by positive reversal, conglomerate and fold tests. The most prominent and intriguing feature of this Late Devonian data set involves a clear distinction in angular dispersion between the lower and upper parts of the studied section. A rather low concentration parameter (k = 13) and several directional anomalies characterize the lower section; in contrast, a much better grouping (k = 46) and a lack of directional outliers is observed for the dual-polarity vectors from the upper flow sequence of the formation. We analysed different mechanisms to account for this directional pattern and found that it is possible in just two ways. One is to assume that secular variation (SV) in the upper sequence is strongly underrepresented, and it is a coincidence that the mean directions of both polarities are statistically antipodal, and the corresponding concentration parameters are statistically equal. The other explanation is to hypothesize that the magnitude of SV can vary several-fold at the same palaeolatitude and over time intervals estimated as 105-106 yr. This is in sharp contrast with other models of SV, where this magnitude has been assumed to be rather time-independent (for a given latitude). Our hypothesis accounts for the observed irregularities in palaeomagnetic data, but makes attempts to establish a correlation between SV and other parameters (geographic latitude, reversal frequency, age, etc.) more difficult. We are aware, however, that more data are needed to refute or confirm it.

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

    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

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

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

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

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

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

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

  2. Paleo-Climate and Glaciological Reconstruction in Central Asia through the Collection and Analysis of Ice Cores and Instrumental Data from the 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.

    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.

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

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

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

    The complex EAS installation of the Tien Shan mountain cosmic ray station which is situated at a height of 3340 m above sea level includes the scintillation and Cherenkov detectors of charged shower particles, an ionization calorimeter and a set of neutron detectors for registering the hadronic component of the shower, and a number of underground detectors of the penetrative EAS component. Now it is intended to expand this installation with a promising method for detecting the radio-emission generated by the particles of the developing shower. The facility for radio-emission detection consists of a three crossed dipole antennae, one being set vertically, and another two - mutually perpendicularly in a horizontal plane, all of them being connected to a three-channel radio-frequency amplifier of German production. By the passage of an extensive air shower, which is defined by a scintillation shower detector system, the output signal of antenna amplifier is digitized by a fast multichannel DT5720 ADC of Italian production, and kept within computer memory. The further analysis of the detected signal anticipates its operation according to a special algorithm and a search for the pulse of radio-emission from the shower. A functional test of the radio-installation is made with artificial signals which imitate those of the shower, and with the use of a N1996A type wave analyzer of Agilent Technologies production. We present preliminary results on the registration of extensive air shower emission at the Tien Shan installation which were collected during test measurements held in Summer 2016.

    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.

    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.

    The best visual expression of mountain permafrost are rockglaciers, which, in contrast to the permafrost itself, can be mapped and monitored directly using remotely sensed data. Studies carried out in various parts of the European Alps have shown surface acceleration of rockglaciers and even destabilization of several such landforms over the two last decades, potentially related to the changing permafrost creep conditions. Changes in rockglacier motion are therefore believed to be the most indicative short- to medium-term response of rockglaciers to environmental changes and thus an indicator of mountain permafrost conditions in general. The ESA DUE GlobPermafrost project develops, validates and implements EO products to support research communities and international organizations in their work on better understanding permafrost characteristics and dynamics. Within this project we are building up a worldwide long-term monitoring network of active rockglacier motion investigated using remote sensing techniques. All sites are analysed through a uniform set of data and methods, and results are thus comparable. In order to quantify the rate of movement and the relative changes over time we consider two remote sensing methods: (i) matching of repeat optical data and (ii) satellite radar interferometry. In this contribution, we focus on the potential of recent high spatial resolution SAR data for the analysis of periglacial processes in mountain environments with special attention to the Ile and Kungöy Ranges of Northern Tien Shan at the border between Kazakhstan and Kyrgyzstan, an area which contains a high number of large and comparably fast (> 1m/yr) rockglaciers and is of interest as dry-season water resource and source of natural hazards. As demonstrated in the past with investigations conducted in the Swiss Alps, the visual analysis of differential SAR interferograms can be employed for the rough estimation of the surface deformation rates of rockglaciers and

    The study presents results of investigation of the observed and projected changes in discharge of seven snow- and glacier-nourished rivers of the northern Tien Shan (south-eastern Kazakhstan). The observed trends were assessed using the long-term (40-60 years) homogeneous daily records of discharge from the gauging stations located in the mountains and unaffected by human activities including water abstraction. Positive trends in discharge were registered at most sites between the 1950s and 2010s with the strongest increase in summer and autumn particularly in 2000-2010s in line with the positive temperature trends. The observed increase was most prominent in the catchments with a higher proportion of glacierized area. At the Ulken Almatinka and Kishi Almatinka rivers, where 16% and 12% of the catchment areas are glacierized, positive trends in summer and autumn discharge exceeded 1% per year. The strongest increase was observed in September indicating that melting period extends in the early autumn. In September-November, the number of days with extreme discharge values, defined as daily values exceeding 95th percentile (calculated for each meteorological season), increased at all rivers. Future changes in discharge were modelled using HBV-ETH hydrological model and four climate change scenarios derived using regional climate model PRECIS with 25 km spatial resolution driven by HadGEM GCM for RCP 2.6 and RCP 8.5 scenarios and HadCM3Q0 and ECHAM5 GCM for A1B scenario. A range of glacier change scenarios was considered. All climate experiments project increase in temperature with the strongest warming projected by the HadGEM-driven simulation for RCP 8.5 scenario and HadCM3Q0-driven simulation for A1B scenario. The projected changes in precipitation varied between models and seasons, however, most experiments did not show significant trends in precipitation within the studied catchments. The exception is a simulation driven by HadGEM GCM for 8.5 RCP scenario which

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

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

    Full Text Available 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.

En la primera sección se explica el origen del DCSE y se retoman los puntos centrales del artículo en el que Dobzhansky lo propuso. En el segundo apartado se desarrollan tres puntos: se hace una reflexión sobre cómo el trabajo científico de dicho autor pone en aprietos la idea de Mayr acerca de que existen "dos biologías"; se cuestiona en qué medida es factible sostener que la columna vertebral de la biología es la evolución; y se plantean algunas implicaciones del DCSE en la filosofía y en la didáctica de la biología. En las conclusiones se argumenta por qué el DCSE debe ser abandonado de una vez por todas.

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

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

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.

  2. 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.

    The Kuru-Tegerek Cu-Au-Mo deposit is situated in a system of Late Carboniferous subduction-related magmatic arcs of the Middle Tien Shan, which together constitute a metallogenic belt of Cu-Au-Mo (±W) porphyry, with local skarns, deposits. The deposit is related to magnetite-series gabbro-diorite to tonalite intrusion. It contains prograde magnesian and calcic skarns with abundant magnetite, associated with gabbro-diorite, and retrograde skarn with Cu mineralization, formed after intrusion of tonalite. Subsequent propylitic alteration introduced abundant chalcopyrite and pyrrhotite, and native Au culminating in zones overprinting magnetite and garnet skarn. Later quartz-muscovite-carbonate veins, formed after intrusion of late mafic quartz monzogabbro dikes, contain chalcopyrite, pyrite, arsenopyrite and other sulfides and sulfosalts, tellurides, and native Au. The earliest retrograde skarn garnet contains gaseous low-salinity (1.7-3.4 wt.% NaCl eq.) fluid inclusions homogenizing at 460-500 °C into vapor, indicating that the early fluid released from crystallizing magma was a low-density vapor. It was followed by more saline (4.0-5.0 wt.% NaCl eq.), high-temperature (400-440 °C) aqueous fluid, as fluid release from the magma progressed. Boiling of this fluid at temperatures of 420 to 370 °C and a pressure of 350-300 bar produced a low-salinity (0.6-1.2 wt.% NaCl eq.), essentially gaseous, and high-salinity (from 39 to 31 wt.% NaCl eq.) brine, with possible metal (including Cu) partitioning into both gaseous and aqueous-saline phases. Boiling was coeval with sulfide deposition in the retrograde skarn. The latest episode of the retrograde skarn stage included direct separation of saline ( 40-42 wt.% NaCl eq.) fluid from crystallizing magma. The separation of saline ( 40 to 14 wt.% NaCl eq.) fluids from a crystallizing magmatic melt continued during the propylitic stage, when fluid cooling from 370 to 320 °C, together with decreasing fO2, caused Cu and especially

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

    Full Text Available Kant afirma que Dios conoce todo a priori, que tiene un intelecto intuitivo y puro; pero el sistema crítico enseña que este aspecto de la divinidad no es cognoscible por nosotros. Entonces, ¿cómo determinar los atributos del intelecto divino si Dios mismo no puede ser objeto de conocimiento? Algunos sostienen que este modo de concebir este atributo divino debe ser comprendido a partir de las convicciones reli-giosas del filósofo. Por el contrario, mostraremos que este peculiar modo de concebir el intelecto de Dios está fundado en un argumento que Kant expone in extensoen las Lecciones de teología filosófica.

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

    2013-12-01

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

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

The writer treats several stages through the Middle Ages, the Reformation period, the Enlightenment and the Twentieth century up to a contemporary project of South African scholars working on a new Semantic Hebrew 'wordbook'. The conclusion in the article is that the nature of a specific dictionary or vocabularly list, for example philological, theological or linguistic, serves particular, legitimate needs.

    Full Text Available To evaluate the safety and efficacy of Tien-Hsien Liquid Practical (THL-P, a Chinese herbal mixture, in patients with refractory metastatic breast cancer, we performed a randomized, double-blind, placebo-controlled, parallel-group, phase IIa pilot trial. Patients were randomly assigned to either receive THL-P or matching placebo and followed up every 4 weeks for 24 weeks. The primary endpoint was changes in the global health status/quality of life (GHS/QOL scale. The secondary endpoints were changes in functional and symptom scales, immunomodulating effects, and adverse events. Sixty-three patients were enrolled between June 2009 and June 2011. The intent-to-treat population included 28 patients in the THL-P group and 11 patients in the placebo group. Compared to the placebo group, the THL-P group had significant improvement from baseline to last visit in GHS/QOL (41.7 versus −33.3; P<0.05, CD3, CD4/CD8, CD19, CD16+56 positive cells (P<0.05, and higher levels of physical, role, emotional, and cognitive functioning, as well as decreased fatigue and systemic side effects. Treatment-related adverse events were mild constipation and localized itching, and no serious adverse events were reported. THL-P appears to be a safe alternative adjuvant treatment for patients with refractory metastatic breast cancer, as it effectively improves QOL and palliates cancer-related symptoms.

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

    The future of mountain water resources in High Asia is of high interest to water managers, development organizations and policy makers given large populations downstream reliant on snow and ice sourced river flow. Together with historical and cultural divides among ex-Soviet republics, a lack of central water management following the Soviet break-up has led to water stress as trans-boundary waters weave through and along borders. New upstream hydropower development, a thirsty downstream agricultural sector and a shrinking Aral Sea has led to increasing tension in the region. Despite these pressures and in contrast to eastern High Asia's Himalayan basins (Ganges, Brahmaputra), little attention has been given to western High Asia draining the Pamir and Tien Shan ranges (Syr Darya and Amu Darya basins) to better understand the hydrology of this vast and remote area. Difficult access and challenging terrain exacerbate challenges to working in this remote mountain region. As part of the Contributions to High Asia Runoff from Ice and Snow (CHARIS) project, we asked how does river flow source water composition change over an alpine-to-plains domain of Kyrgyzstan's Naryn River in the Syr Darya basin? In addition, what may the future hold for river flow in Central Asia given the differing responses of snow and ice to climate changes? Utilizing a Rapid Hydrologic Assessment methodology including a suite of pre-field mapping techniques we collected in situ water chemistry data at targeted, remote mountain sites over 450km of the Naryn River over an elevation gradient from glacial headwaters to the lower lying areas - places where people, hydropower and agriculture utilize water. Chemical and isotope tracers were used to separate stream flow to understand relative dependency on melt waters as the river moves downstream from glaciers and snow covered areas. This case study demonstrates a technique to acquire field data over large scales in remote regions that facilitates

Les entités géopolitiques et sociopolitiques qui en résultent évoluent, elles aussi, proportionnellement et rationnellement aux motivations des individus en partance. Ainsi, les exilés forcés rêvaient de retrouver leur chère Haïti, les nouveaux primo-arrivants sont des individus qui cherchent à se ré-enraciner dans un terreau aux airs d’ailleurs. Le diasporique est-il un individu dont l’identité est figée ? Dans cet article, une étude statistique simple cherche à démontrer l’évolution des mentalités des jeunes Haïtiens à travers un questionnement des identités et des orientations culturelles. Des dynamiques se font jour montrant que la diaspora est fluctuante comme les identités et les cultures qui la composent.The Push factors of Haitian emigration have completely changed since the late 1950s which marked the beginning of this movement with the Duvalier regime. The geopolitical and sociopolitical entities which result from it are changing as well, in proportion and accordance with the motivations of the people who leave. Thus, the forced exiles dreamt of going back to their dearest Haiti, the latest newly-arrived immigrants are individuals who desire to re-root into a land that sounds like “elsewhere”. Must the diasporic individual’s identity be stable? In this article, a simple survey seeks to shed light on the changing mentalities of young Haitians, examining their identities and cultural choices.  Emerging trends show that diaspora is a flow, not unlike the identities and the cultures of which it is composed.

Esta clasificación describe los apéndices perforados como aquellos con la presencia de un orificio visible en el apéndice o la presencia de un fecalito libre en la cavidad y ha cambiado el manejo postoperatorio actual. Objetivo. Determinar si el cambio en la definición macroscópica de la apendicitis aguda tiene alguna influencia en la duración de la estancia hospitalaria y la tasa de complicaciones dado el cambio en el manejo antibiótico postoperatorio. Materiales y métodos. Se llevó a cabo un rastreo de aquellos pacientes llevados a cirugía con diagnóstico de apendicitis aguda durante el primer semestre del año 2009 y el segundo semestre del año 2011 en la Fundación HOMI. Se excluyeron los pacientes llevados a laparoscopia diagnóstica por estudio del dolor abdominal, apendicectomias incidentales y los pacientes manejados en el protocolo de apendicectomía de Intervalo. Resultados. Se observó una disminución en el número de días de hospitalización/año y en el número de dosis de antibiótico/año y reducción en el número de complicaciones, lo cual demuestra que la clasificación y el protocolo de manejo actual no se correlacionan con un aumento en el número de complicaciones y se asocia con menores costos. Conclusión. El cambio en la clasificación macroscópica y el aportar la nueva definición sobre apendicitis perforada ha logrado disminuir la estancia hospitalaria y la cantidad de antibióticos utilizados sin una repercusión significativa en la tasa de complicaciones.

    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.

Dans ce type de système, chaque exercice met en jeu un micro-monde d’objets graphiques sur lesquels l’enfant utilisateur peut agir (modification, déplacement, suppression d’objets, etc., en formulant des requêtes en langage naturel auxquelles le système répond. Nous présentons un logiciel éducatif de cette famille, que nous avons conçu et développé ces dernières années. Nous décrivons en premier lieu les objectifs pédagogiques et les fonctionnalités de notre logiciel, puis le système que nous y utilisons pour le traitement automatique du langage. Nous décrivons ensuite l’ensemble des composants qui structure les connaissances qu’il a été nécessaire de modéliser, articuler et gérer pour la réalisation de ce système.This paper deals with the development of educational software, which proposes, in a multimedia, multimodal and reactive environment favoring natural language expression, piagetian games designed for natural language learning. In such systems, each exercise brings into play a micro-world of graphic objects on which the user can act (for example to modify, move or withdraw the objects, by composing natural language queries to which the system gives an answer. We present a software of this type, that has been designed and implemented these last years. We firstly describe the educational objectives and the functionality of the software, then the natural language processing system which is used in it. Finally we describe the set of components that structures knowledge modeled, articulated and managed in order to carry out this educational system.

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

    Full Text Available 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 formation 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 – 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 formation 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.

  8. 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.

    Full Text Available Chretien de Troyes, the most famous of the French 12th-century authors of chivalric romaces, comes to a very personal view of violence towards the end of his writing career, in his Perceval or the grail story. While in his previous works, the first of which was Erec and Enid, the object of the present article, he abided by the commonly accepted norms concerning the description of »violence«: there's no »abstract violence«, and it should never befall and idea or a tradition while the violence against the individual is a common occurrence considered "creative" and legitimate, if not indispensable, for the making of social hierarchy and order, violence ceases to be a topic of interest in his last, unfinished text.

Indeed, his theory of change was one of his fundamental contributions to history of philosophy. Thirty years ago this opinion was questioned and the argument was recently repeated in a revised edition of Anaximenes. So far, I have no notice that such question has been answered. In the present essay I want to argue that, although there is something erroneous in the traditional interpretation of Anaximenes theory of change, it is not what the objectors say it is: truly, Anaximenes possess an important theory of change, of which we have significant antique evidence.

    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.

    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.

    The renin-angiotensin system (RAS) plays an important role in the regulation of blood pressure. In order to clarify the signaling mechanism mediated by angiotensin 2 receptor, Gq-protein binding amino acid residues of this receptor were clarified by site-directed mutagenesis study. Amino acid residues in the carboxyl tail region were changed by alanines, individually. These mutated receptors were expressed stably in CHO cells, and GTP effect and second messenger molecules were determined, and three residues (Y 312, F313 and L 314) in this region were determined to be concerned for the binding of Gq protein. The other signaling systems, Gi, MAP kinase, JAK-STAT mediated, were reported to be concerned for this receptor. Novel drags for high blood pressure therapy would be explored by clarifying these signaling mechanisms. (author)

    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.

    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.

    2015-03-01

    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.

  9. Living Joyfully after Losing Social Hope: Kierkegaard and Chrétien on Selfhood and Eschatological Expectation

    Directory of Open Access Journals (Sweden)

    J. Aaron Simmons

    2017-02-01

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

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

    The electrical stimulation of the auditory nerve can elicit auditory sensations in the subjects with sensorineural deafness. Each stimulating electrode of an electrode array of the multi-channel cochlear implants may stimulate a distinct neural population. However, a great deal of current spreads from each electrode throughout a lymph because of the high electrical conductivity of the lymph liquid. This phenomenon causes the transmitted information to be reduce due to channel interactions. Even if the number of electrodes is increased, the transmitted information will be limited because of current spread. We have proposed the Tripolar Electrode Stimulation Method (TESM) which may succeed in narrowing the stimulation region and continuously moving the stimulation site for the cochlear implants. We evaluate whether or not TESM works according to a theory which is based on the numerical analysis using the auditory nerve fiber model consisted of unmyelinated and myelinated segments. In this simulation, the neural site and the am of the excited fibers are compared with the compound action potentials which we obtained through animal experiments. As a result, based on the numerical analysis using this model, it is also proved that the anodal/cathodal threshold stimulation current ratio increases by decreasing unmyelinated segment between the inner hair cell and the habenula perforate. Also by comparing the result of the numerical analysis with that of the animal experiment, It is suggested that an effect of the unmyelinated segment is not significant. Based on their results mentioned above, we succeed in narrowing a Stimulation region by controlling the am of the currents emitted from the electrodes on both sides. Also we succeed in continuously moving a stimulation site by changing the ratio of the currents emitted from the electrodes on both sides. 11 refs., 14 figs., 1 tab.

    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 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.

M. y Al Día, en ciudadanos mayores de 18 años, y a su vez explorar la apreciación de las personas involucradas en el proceso de edición de los diarios sobre la producción de tal contenido. Para dichos fines se utilizó una metodología cualitativa del análisis del discurso; se obtuvieron respuestas como "hace más agresiva a la gente", entre otras, constatando que el cubrimiento de la violencia genera un impacto de temor y preocupación en la audiencia. Se propone a las empresas editoriales supervisar el manejo y el tratamiento que le dan a la nota roja.

Un repaso hacia el origen de un nuevo medio con el que ya convivimos y una mirada puesta en el presente de su desarrollo vertiginoso.

    Full Text Available Considerado uno de los más destacados especialistas a nivel internacional de la criminología “garantista”, este argentino-catalán es también uno de esos tipos que incomoda al poder. Siempre. Esté donde esté. Desde la academia, en su puesto de profesor titular de ejecución penal y derecho penitenciario en la universidad de Barcelona, o desde la acción, a través del Observatorio de Derechos Humanos que en 2001 ayudó a crear con el objetivo de abordar el complejo mundo penitenciario. Hipercrítico de la situación argentina y mundial por sus fracasadas políticas de encierro indiscriminado y violación sistemática de los derechos humanos de los presos, Iñaki Rivera Beiras en entrevista con Alfilo habla de todo lo que sucede adentro y afuera de la institución insigne del sistema penal: la cárcel.

    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.

Apesar da morte prematura – decorrente do golpe de Estado de 1973 –, Jara deixou um legado artístico variado que se constitui em fonte privilegiada para pensar o contexto chileno dos anos 1960 e 1970, período marcado pela forte atuação de movimentos sociais que tinham como plano de fundo uma crescente polarização política. Filiado ao Partido Comunista, o músico se valeu do potencial comunicativo e expressivo da canção para defender a necessidade de se promoverem mudanças políticas estruturais no país, as quais necessariamente passariam pela esfera da cultura. Perguntando pela presença de elementos identitários em sua obra musical, analisaremos os diálogos estabelecidos pelo artista com a conjuntura política nacional, apontando para a heterogeneidade do repertório englobado sob o termo Nova Canção Chilena.Palavras-chave: Víctor Jara – Nova Canção Chilena – Unidade Popular. Abstract: 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.Keywords: Víctor Jara – Chilean New Song Movement – Popular Unity.

    Full Text Available This paper aims to draw the religious life in Sarnath (and Varanasi as accounted by the Chinese travellers—Fa-Hien and Hiuen-tsang. The accounts not only talk about the stupas, pillars, statues built by King Ashoka; vihars and monks (bhikshus living in those vihars but also contain the first preachings of Lord Buddha, establishment of Sangha and the story of Mrigajataka that remain significant. With the increased popularity of Buddha dharma in China, the Chinese were attracted towards travelling to India. They came to India mainly with the intentions to visit the places related to the fond memories of Lord Buddha, to study the Buddha religion and philosophy and carry the copies of the Buddhist compositions. Fa-Hien and Hiuen-tsang occupy significant places among these Chinese travellers. These accounts can be associated with ancient history as well as with historical geography, religion and philosophy. While Fa-hien in his journey details had described about the Buddha Empire, Hiuen-tsang highlighted the civilisation of India and its cultural landscape, albeit it has been often accepted by the historians that these accounts of their journeys should be considered as significant only when they are backed by historical evidences. They opine that these travellers were mainly influenced by the Buddha dharma and therefore, their accounts are liable to containing exaggerated journey details. It is true that the journey details contain few imaginary instances; nevertheless, these accounts have been validated by the remnants, stupas and vihars at the sites.

    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.

A presente revisão objetiva analisar as principais plantas que serviram como base de progresso para a moderna terapêutica anestesiológica através de sua utilização como modelos moleculares para síntese orgânica na moderna química fina de ponta, bem como fornecer mais embasamento sobre benefícios, potenciais efeitos adversos, interações e risco de efeitos colaterais que possam afetar o ato anestésico no paciente cirúrgico usuário habitual de fitoterapia. CONTEÚDO: Considerações anestesiológicas selecionadas são discutidas focalizando uma pequena revisão sobre ervas medicinais mais populares que foram essenciais no desenvolvimento de uma farmacologia anestesiológica e, ainda, as potenciais interações de plantas medicinais usadas por pacientes para tratar suas doenças ou controlar seus sintomas com drogas sintéticas usadas na anestesia. CONCLUSÕES: Enquanto a Medicina especializada fascina-se cada vez mais com a tecnologia avançada de novos fármacos e de fantásticos monitores, cresce em vários países o número de pacientes que desejam uma abordagem mais holística com rejeição dos modernos métodos de tratamento, optando por chás, meditações, dietas vegetarianas, anti-oxidantes, entre outros.

This review aimed at analyzing major herbs that were the basis for the progress of modern anesthetic therapy through their use as molecular models for organic synthesis in fine leading edge modern chemistry, as well as shedding more light on the advantages, potential adverse effects, interactions and risks for side-effects which may affect anesthesia in surgical patients users of phytotherapy. CONTENTS: Selected anesthesiologic considerations are discussed focusing a brief review of popular herbs essentials on the development of anesthetic pharmacology and the potential drug-herb interactions between synthetic drugs used in anesthesia and the medicinal herbs used by patients in their illness and symptoms management. CONCLUSIONS: While specialized Medicine is increasingly fascinated by the advanced technology of new drugs and fantastic monitors, there is an increasing trend in several countries for a more holistic approach and rejection of new treatment methods, with an option for teas, meditation, vegetarian diets and anti-oxidants, among others. It is the anesthesiologist’s role to evaluate how much pharmacognosy and pharmacobotany knowledge may help him in the anesthetic practice and, especially, in patients safety.

    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.

    Full Text Available 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.

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.

  6. ¿Tiene utilidad el tratamiento preoperatorio con ácido ursodeoxicólico en la reducción de las recidivas en la pancreatitis aguda biliar?

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

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

The two groups did not show significant differences regarding any of the studied parameters. We registered 7/30 (23.3% relapses in UCA group, versus 9/42 (21.4% relapses in the control group (p = 0.85.

UCA treatment duration did not seem to be related with the occurrence of pancreatitis relapse.

    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.

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 and aims: Early oral feeding after colorectal resections is one of the many factors that contributes to enhance recovery after surgery, mainly impacting on postoperative ileus. The aim of this study was to evaluate the impact of early postoperative oral feeding in patients undergoing elective colorectal resection. Methods: Patients were randomly assigned to either a conventional postoperative dietary regimen or a free diet on the first postoperative day. Results: Altogether 29 patients were enrolled. Clinical characteristics were similar in both groups. Good nutritional status was seen in 86% of patient in the traditional care (TRAD group versus 46% in the early fed (EF group (pAntecedentes y objetivos: La alimentación oral precoz tras las resecciones colorrectales es uno de los muchos factores que contribuyen a favorecer la recuperación tras la cirugía, teniendo sobre todo una influencia en el íleo posoperatorio. El propósito de este estudio fue evaluar el impacto de la alimentación oral precoz posoperatoria en pacientes sometidos a resección colorrectal programada. Métodos: Se distribuyó al azar a los pacientes para recibir un régimen alimenticio posoperatorio convencional o una dieta libre en el primer día de posoperatorio. Resultados: Se reclutó a un total de 29 pacientes. Las características clínicas fueron similares en ambos grupos. Se observó buen estado nutritivo en el 86% de los pacientes con la atención tradicional (TRAD frente al 46% en el grupo con alimentación precoz (EF (p < 0,05.

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

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

    Full Text Available Este estudio longitudinal cuasi-experimental con grupo de comparación examinó el efecto de asistir desde 1 a 4 años de edad a jardines de la Junta Nacional de Jardines Infantiles (JUNJI de Chile sobre el desarrollo/aprendizaje de los párvulos y el efecto diferencial de asistir a partir de los 3 años. El muestreo fue bietápico (41 jardines y 427 niños al inicio y estratificado por región del país. El grupo de comparación, con características socioeconómicas similares (184 niños al inicio, no asistía a sala cuna. Los niños fueron evaluados anualmente con el Inventario de Desarrollo Battelle. También se recogieron variables familiares y educativas con entrevistas semi-estructuradas y pautas de observación. Comparaciones usando Propensity Score Matching y análisis de Mínimos Cuadrados Ordinarios arrojaron que alrededor del 80% de los niños cursa un desarrollo normal, independientemente de que asistan a los jardines infantiles JUNJI o permanezcan en sus casas. Asistir desde los 3 años tendría un efecto positivo en el desarrollo infantil. La calidad de las prácticas pedagógicas en lactantes y la actitud didáctica familiar explicarían mayormente el desarrollo de los párvulos.This quasi-experimental longitudinal study with comparison group examined the effect on the learning and developmental levels of infants attending the National Preschool Association (JUNJI nursery schools in Chile (between 3 months and 4 years of age and the differential effect of attending them from 3 years of age onward. A two-stage (41 nurseries and 427 children at the beginning and stratified sample by region was used. The comparison group, with similar socioeconomic characteristics (184 children at the beginning, did not attend a nursery school. Children were assessed yearly with the Battelle Developmental Inventory. Family and educational variables were collected using semi-structured interviews and an observational guideline. Comparisons using Propensity Score Matching and Least Squares analysis showed that nearly 80% of the children were learning and developing according to their age, regardless of whether they were attending a JUNJI nursery school or staying at home. Attending from 3 years of age onwards is likely to have positive effects on infant development. The quality of pedagogical practices in babies and family educational attitudes are the most probable explanations for children development.

    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.

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.

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

    Diffusion of knowledge is expected to be huge when agents are open minded. The report concerns a more difficult diffusion case when communities are made of stubborn agents. Communities having markedly different opinions are for example the Neocreationist and Intelligent Design Proponents (IDP), on one hand, and the Darwinian Evolution Defenders (DED), on the other hand. The case of knowledge diffusion within such communities is studied here on a network based on an adjacency matrix bui...

    Full Text Available The Bui hydropower plant plays a vital role in the socio-economic development of Ghana. This paper attempt to explore the combined effects of climate-land use land cover change on power production using the (WEAP model: Water Evaluation and Planning system. The historical analysis of rainfall and stream flow variability showed that the annual coefficient of variation of rainfall and stream flow are, respectively, 8.6% and 60.85%. The stream flow varied greatly than the rainfall, due to land use land cover changes (LULC. In fact, the LULC analysis revealed important changes in vegetative areas and water bodies. The WEAP model evaluation showed that combined effects of LULC and climate change reduce water availability for all of demand sectors, including hydropower generation at the Bui hydropower plant. However, it was projected that Bui power production will increase by 40.7% and 24.93%, respectively, under wet and adaptation conditions, and decrease by 46% and 2.5%, respectively, under dry and current conditions. The wet condition is defined as an increase in rainfall by 14%, the dry condition as the decrease in rainfall by 15%; current account is business as usual, and the adaptation is as the efficient use of water for the period 2012–2040.

  6. Evaluation of [methyl-{sup 3}H]L655,708 and [ethyl-{sup 3}H]RY80 as putative PET ligands for central GABA{sub A} receptors containing {alpha}5 subunit

    1999-10-01

    Two selective radioligands of gamma aminobutyric acid (GABA){sub A} receptors containing the {alpha}5 subunit, [{sup 3}H]L655,708 and [{sup 3}H]RY80, were evaluated in rats as potential in vivo tracers for positron emission tomography (PET). Brain uptake index (BUI), a measure of first pass extraction, was moderate for [{sup 3}H]L655,708 (BUI of 59%) and good for [{sup 3}H]RY80 (BUI of 96%). This finding was consistent with their in vitro binding to plasma proteins of {approx}76% and 50%, respectively. Following intravenous injection of either radioligand, radioactivity in plasma was measured and uptake characteristics were assessed in brain within a time period relevant to PET scanning (up to 90 min). Discrete brain regions, such as frontal cortex, striatum, hypothalamus, thalamus, hippocampus, colliculi, medulla, and cerebellum, were sampled and the temporal distribution of radioactivity analysed. Despite the reasonable delivery to the brain, neither of the radioligands had sufficient retention in the tissues rich in {alpha}5-containing GABA{sub A} receptors to achieve a good selective signal. For both radioligands, a maximal tissue:cerebellum ratio of 1.5 was seen in hippocampus at 10 min after injection. Thus, neither of the compounds studied shows potential for further development as an in vivo PET ligand.

    2014-01-01

    Four river systems on the Wisconsin shoreline of Lake Michigan are designated Areas of Concern (AOCs) because of severe environmental degradation: the Lower Menominee River, Lower Green Bay and Fox River, Sheboygan River, and Milwaukee Estuary. Each AOC has one or more Beneficial Use Impairments (BUIs) that form the basis of the AOC designation and that must be remediated or otherwise addressed before the AOC designation can be removed. All four of these AOCs have BUIs for benthos (bottom-dwelling or benthic invertebrates), and all but the Menominee River have a BUI for plankton (free-floating algae and invertebrates, or phytoplankton and zooplankton, respectively). The U.S. Geological Survey collected samples in 2012 at these four AOCs and at six non-AOCs to support the evaluation of the status of aquatic communities in the benthos and plankton at the AOCs. Samples were collected during three periods representing spring, summer, and fall. Benthos samples were collected using a dredge grab sampler and artificial substrates; plankton samples were collected using a tow net for zooplankton and a vertical water sampler for phytoplankton. Benthos and plankton were identified to the lowest possible taxonomic category and counted; samples for documenting water temperature, pH, and specific conductance, as well as sediment particle size and organic carbon were also collected during biological sampling.

    This study investigated the contamination status of PCBs, PBDEs and HBCDs in human and possible exposure pathways in three Vietnamese e-waste recycling sites: Trang Minh (suburb of Hai Phong city), Dong Mai and Bui Dau (Hung Yen province), and one reference site (capital city Hanoi) by analysing human breast milk samples and examining the relationships between contaminant levels and lifestyle factors. Levels of PBDEs, but not PCBs and HBCDs, were significantly higher in Trang Minh and Bui Dau than in the reference site. The recyclers from Bui Dau had the highest levels of PBDEs (20-250 ng g(-1) lipid wt.), higher than in the reference group by two orders of magnitude and more abundant than PCBs (28-59 ng g(-1) lipid wt.), and were also the only group with significant exposure to HBCDs (1.4-7.6 ng g(-1) lipid wt.). A specific accumulation, unrelated to diet, of low-chlorinated PCBs and high-brominated PBDEs was observed in e-waste recyclers, suggesting extensive exposure to these compounds during e-waste recycling activities, possibly through inhalation and ingestion of dust. The estimated infant intake dose of PBDEs from breast milk of some mothers occupationally involved in e-waste recycling were close to or higher than the reference doses issued by the U.S. EPA.

  9. Masonería y política: una nueva cara del rito masonería- revolución. ¿La masonería tiene una ideología y "hace política"? ¿Los políticos fueron y son tales porque fueron masones y los masones siempre fueron hombres que tomaron partido o fueron de partido?

    Full Text Available RESUMEN: ¿La Masonería es depositaria de una doctrina política y de un programa político? Hubo un tiempo en que «política» significaba educación, gobierno de la polis, es decir, de los ciudadanos (que para ser titulares de derechos y de deberes debían ser necesariamente cultos. 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.

Masonry has been attributed whith partisan objectives: the struggle against the power of the clergy and religiuous doctrine, against the monarchy (although this is not true for Great Britain, Holland, Belgium, Greece and often not true for Italy, Spain and even France, where masonry was pro-Bourbon and pro-Napoleon. Against militarism (although many officers and non-commissioned officers were masons... The authenticity of the objectives of masonic organizations can be verified by analysing whether certain famous masons were only famous or were actually masons as well.

  12. Short-term effects of prescribed fire for pasture management on soil water repellency in the Central Pyrenees (NE-Spain)

    The decrease of livestock grazing during the last decades in the Central Pyrenees has led to a regression of grasslands in favour of shrublands, mainly composed by Echinospartum horridum. Prescribed burning might be a suitable tool for the control of this species that limits pastures development and therefore, the reclamation of grasslands; although, its effects on soil properties are still uncertain [1]. Controlled burnings are usually performed in spring or autumn, when soil moisture is high and temperature low, being easier to control and also reducing its effects on soil properties. However, burning during the wet seasons can increase the risk of soil erosion as the vegetation cover is partially destroyed. In this sense, soil water repellency (SWR) plays an important role reducing the infiltration rates and, thus, increasing runoff and soil erosion [2]. Then, it is of special interest to study parameters that influence SWR such as soil moisture, soil organic carbon (SOC) content and soil biological activity [3]. The aim of this work is, to analyse the effects of controlled burning on SWR as well as some of the influencing factors on this parameter. To achieve this, soil sampling was carried out in two prescribed fire events that took place in the Central Pyrenees: Tella (April, 2015) and Buisán (November, 2015). Temperature was simultaneously recorded during the fire via thermocouples placed at the surface level and at 1 cm, 2 cm and 3 cm depth. In each event, topsoil was scrapped and sampled from 0-1 cm, 1-2 cm and 2-3 cm depth in each sampling point (3 for Tella and 4 for Buisán) just before and immediately after burning. We analysed SWR persistence (Water Drop Penetration Time, WDPT) and intensity (Ethanol Percentage Test, EPT) as well as total C and N, microbial C, β-glucosidase activity, soil moisture and pH. Temperature measurements indicated a higher fire intensity in Tella than in Buisán burning. Surface unburned samples presented extreme SWR values

    The lower Genesee River and Rochester Embayment of Lake Ontario are a designated Area of Concern (AOC) under the binational Great Lakes Water Quality Agreement. The “degradation of phytoplankton and zooplankton populations” or plankton Beneficial Use Impairment (BUI) was classified as unknown and in need of further assessment in this AOC because water quality data suggested plankton communities could be effected and community data were either unavailable or indicated impacts. The plankton BUI may now be obsolete because local contaminant sources have been largely eliminated. The present study was conducted between July 2013 and August 2014 to assess the BUI-removal criteria: “AOC plankton bioassays confirm that toxicity in ambient waters (i.e., no growth inhibition) is not significantly higher than comparable non-AOC controls”. Acute and chronic toxicity of waters from 13 sites were quantified seasonally using standardized bioassays with the green alga Pseudokirchneriella subcapitata and water flea Ceriodaphnia dubia to test the hypothesis that toxicity of waters from AOC sites was not higher than that of waters from comparable non-AOC reference sites. Survival and reproduction of C. dubia did not differ significantly between site types, systems, or months. The growth of P. subcapitata did not differ between site types, but differed among systems and months. All results indicate that waters from AOC sites were no more toxic to both plankton species than waters from reference sites. Assuming test species represent natural plankton assemblages, water quality should not negatively affect survival and growth of resident plankton populations in the Rochester Embayment AOC.

    In 1904, the government of Rafael Reyes, divided the great Cauca in several states, this process continued until 1910 when Popayan remained located in the present-day Cauca. This signified the loss of hegemony over the old Sovereign State. The present work objective to show the way as these dominant castes did not only take advantage of the festival of the First Centennial of the Independence, 1910, to build its new identity, its relation with the past, its collective memory, but also for bui...

    In this Note, we present a method to solve numerically the Stokes equation for the incompressible flow between two immiscible fluids presenting very different viscosities. The resolution of the finite element systems of equations is performed using Uzawa's method. The stiffness matrix conditioning problems related to the very important viscosity ratios are circumvented using an new iterative scheme. A numerical example is proposed to show the efficiency of this approach. To cite this article: T.T.C. Bui et al., C. R. Mecanique 336 (2008).

    Hydroelectric Power (HEP) is proving to be a good alternative to carbon based energy. In the past hydropower especially large scale hydro attracted significant criticism as a result of its impact on the environment. A new breed of hydroelectric dam is in the offing. The aim is to have as little a footprint as possible on the environment in both pre and post construction phases and thus minimize impact on biodiversity whilst producing clean renewable energy. The Bui dam is 400 MW scheme currently under development on the Black Volta River in the Bui national park in Ghana. The reservoir created by the Bui barrage is expected to impact (through inundation) the habitat of two species of hippos know to exist in the park, the Hippopotamus amphibius and the Choeropsis liberiensis. Computer-based models present a unique opportunity to assess quantitatively the impact of the new reservoir on the habitat of the target species in this case the H. amphibious. Until this undertaking, there were very few studies documenting the habitat of the H. amphibious let alone model it. The work and subsequent presentation will show the development of a habitat model for the Hippopotamus amphibius. The Habitat Information retrieval Program based on Streamflow Analysis, in short HIPStrA, is a one dimensional (1D) in-stream, spatially explicit hybrid construct that combines physico-chemical evidence and expert knowledge to forecast river habitat suitability (Hs) for the Hippopotamus amphibius. The version of the model presented is specifically developed to assess the impact of a reservoir created by a hydroelectric dam on potential dwelling areas in the Bui gorge for hippos. Accordingly, this version of HIPStrA simulates a special reservoir suitability index (Rsi), a metric that captures the”hippo friendliness” of any lake or reservoir. The impact of measured and simulated flood events as well as low flows, representing extreme events is also assessed. Recommendations are made for the

    The Black Volta watershed is approximately 134 000 km2 in size at the gauge at Bamboi. It is part of the main 414 000 km2 Volta system. The Volta river was dammed at Akosombo in 1965 resulting in the largest man-made lake in the world, the Volta Lake. The Bui dam is a new 400 MW scheme currently under development on the Black Volta River in the Bui national park in Ghana.

SSIs increase postoperative morbidity and mortality, and may require hospital admission, intravenous antibiotics, and even surgical reintervention. Risks associated with SSIs are related to both host and perioperative factors. However, a vast majority of these infections are preventable. More recently, quality initiative programs such as American College of Surgeons National Surgical Quality Improvement Program are expanding their roles to help better monitor adherence to improvement measures. Indeed, standardizing preoperative antibiotic prophylaxis timing is perhaps the most persuasive example and this has been integral to reducing postoperative SSI rates. Herein, the authors provide an update on the epidemiology, risk factors, identification, and management of wound infections following abdominal surgery.

    This article concerns a report by Nguyen Thi Hien, chairperson of Nghi Loc District Women's Union on the contribution of the Japan International Cooperation Agency (JICA) project to their organization. She states that prior to the start of the JICA project, the women's union had a lot of campaigns for maternal and child health and family planning. However, the impact was not strongly felt. After the implementation of the JICA project, women in the district have become interested and excited about the various activities conducted under the project. Subsequently, more women understood the correct way to take care of their health and their children's health. Furthermore, more people in the district frequently use the services of commune health centers and district health centers. In the family planning field, contraceptive prevalence rate has increased and the number of abortions and menstrual regulations has been reduced. Despite the achievements of the campaign, the district still has a few big problems to address. These problems include: 1) a gap between commune health centers in remote areas and those near the district health centers; and 2) a low level of family planning acceptance in Catholic communes.

    Phenomenon of urban heat islands (UHI) was researched by many authors of scientific community. More investigators were focused on heat island of tropical city. (for example: Tropical urban heat islands: climate, buildings and greenery / Nyuk Hien Wong and Yu Chen. - London, 2009; 259 p.) However dynamics UHI in arctic, subarctic and sharp continental climates is poorly investigated. This situation is due to the fact that there isn't large cities in Europe and Northern America within that climate type. In this paper we investigate long-term, seasonal and diurnal dynamics UHI intensity for more than 20 cities of the Russian Federation (large than 100 000 population). Was calculated and analyzed changes UHI intensity within days and year. Also was detailed reviewed extreme values UHI and was discussed their relation with synoptic situations. In that investigation data created by regular state meteorological observation ROSHYDROMET network was used. For every city we selected couple of stations: one located into city in high and midrise buildings area (including extensive lowrise and high-energy industrial - LCZ classification) and second one located in rural site (sparsely built or open-set and lightweight lowrise according LCZ classification). Also couples of stations must be close by distance (less than 100 km) and altitude. For selection operation was constructed spatial database in ESRI ArcGIS Desktop environmental. Advantage investigation UHI of Russian city is diversity of climate condition. Selected cities locate within territory from 40N to 70N latitude and from 20E to 160E. That fact allows research UHI phenomenon in space term. Were detected intensity UHI patterns depends on geographical location of the city.

    Nano-structured TiO2 electrodes, suitable for dye sensitized solid-state solar cells were prepared by a new simple spraying technique (SPT). Physical properties of these electrodes were compared with the electrodes prepared by the `doctor blade’ technique (typical sliding method, DB). Dye sensitized solid-state solar cells, comprising of CuI as the hole conductor, were fabricated with these electrodes and enhanced photo responses were obtained with SPT electrodes. The effects of additives, either to the spray solution or to the hole conductor on the photoresponses of the above devices were also studied. The cells fabricated with SPT electrodes containing Al(BuiO)3 showed ∼ 2.4% efficiency and addition of 1-ethyl-3-methyl imidazolium thiocyanate into CuI layer further enhanced the efficiency up to 2.75% under the irradiance of 100 mW cm-2(AM1.5).

    Synthesis and characterization of nanotubes and nanowires constitute an important part of nanoscience since these materials are essential bui lding units for several devices. We have prepared aligned carbon nanotube bundles and Y-junction nanotubes by the pyrolysis of appropriate organic precursors. The aligned bundles are useful for field emission display while the Y-junction nanotubes are likely to be useful as nanochips since they exhibit diode properties at the junction. By making use of carbon nanotubes, nanowires of metals, metal oxides and GaN have be en obt a ined. Both the oxide and GaN nanowires are single crystalline. Gold nanowires exhibit plasmon bands varying markedly with the aspect ratio. GaN nanowires show excellent photoluminescence characteristics. It has been possible to synthesise nanotubes and nanowires of metal chalcogenides by employing different strategies.

    2009-01-01

    Nuclear quadrupole resonance (NQR) a highly promising new technique for bulk explosives detection: relatively inexpensive, more compact than NMR, but with considerable selectivity. Since the NQR frequency is insensitive to long-range variations in composition, mixing explosives with other materials, such as the plasticizers in plastic explosives, makes no difference. The NQR signal strength varies linearly with the amount of explosive, and is independent of its distribution within the volume monitored. NQR spots explosive types in configurations missed by the X-ray imaging method. But if NQR is so good, why it is not used everywhere? Its main limitation is the low signal-to-noise ratio, particularly with the radio-frequency interference that exists in a field environment, NQR polarization being much weaker than that from an external magnetic field. The distinctive signatures are there, but are difficult to extract from the noise. In addition, the high selectivity is partly a disadvantage, as it is hard to bui...

    Several in vivo techniques have been developed to study and measure the uptake of CNS compounds into the brain. With these techniques, various parameters can be determined after drug administration, including the blood-to-brain influx constant (K(in)), the permeability-surface area (PS) product, and the brain uptake index (BUI). These techniques have been mostly used for drugs that are expected to enter the brain via transmembrane diffusion or by carrier-mediated transcytosis. Drugs that have limitations in entering the brain via such pathways have been encapsulated in nanoparticles (based on lipids or synthetic polymers) to enhance brain uptake. Nanoparticles are different from CNS compounds in size, composition and uptake mechanisms. This has led to different methods and approaches to study brain uptake in vivo. Here we discuss the techniques generally used to measure nanoparticle uptake in addition to the techniques used for CNS compounds. Techniques include visualization methods, behavioral tests, and quantitative methods.

This underscores the need for forensic psychologists to evaluate the psychopathology and underreporting of symptoms. The standard procedure employed by practitioners is to administer the MMPI-2 to both parents in order to assess psychopathology and the underreporting of symptoms (Bow & Quinnel, 2001. To estimate the efficacy of this procedure, the MMPI-2 was administered in a forensic setting to 126 parents involved in parental disputes over child custody, and 105 parents lay in psychopathology under the standard instructions. Results showed that the typical protocol used in forensic assessment was inefficacious for the detection of underreporting. The implications of these results on forensic practice are discussed.

    2000-05-01

    Carbon-11 labelled RS-15385-197 and its ethylsulphonyl analogue, RS-79948-197, were evaluated in rats as potential radioligands to image central {alpha}{sub 2}-adrenoceptors in vivo. The biodistributions of both compounds were comparable with that obtained in an earlier study using tritiated RS-79948-197 and were consistent with the known localisation of {alpha}{sub 2}-adrenoceptors. The maximal signals (total to non-specific binding) were, however, reduced, in the order [{sup 11}C]RS-79948-197 < [{sup 11}C]RS-15385-197 < [{sup 3}H]RS-79948-197, primarily due to the difference in radiolabel position (O-methyl for carbon-11 compared with S-ethyl for tritium). This resulted in the in-growth of radiolabelled metabolites in plasma, which, in turn, contributed to the non-specific component of brain radioactivity. Nonetheless, the signal ratio of {proportional_to}5 for a receptor-dense tissue compared with the receptor-sparse cerebellum, at 90-120 min after radioligand injection, encouraged the development of [O-methyl-{sup 11}C]RS-15385-197 for human positron emission tomography (PET). Unfortunately, in two human PET scans (each of 90 min), brain extraction of the radioligand was minimal, with volumes of distribution more than an order of magnitude lower than that measured in rats. Following intravenous injection, radioactivity was retained in plasma and metabolism of the radiolabelled compound was very low. Retrospective measurements of in vitro plasma protein binding and in vivo brain uptake index (BUI) in rats demonstrated a higher protein binding of the radioligand in human compared with rat plasma and a lower BUI in the presence of human plasma. It is feasible that a higher affinity of RS-15385-197 for human plasma protein compared with receptor limited the transport of the radioligand. Although one of the PET scans showed a slight heterogeneity in biodistribution of radioactivity which was consistent with the known localisation of {alpha}{sub 2}-adrenoceptors in

    Three oligomeric organophosphorus flame retardants (o-PFRs), eight monomeric PFRs (m-PFRs), tetrabromobisphenol A (TBBPA), and polybrominated diphenyl ethers (PBDEs) were identified and quantified in surface soils and river sediments around the e-waste recycling area in Bui Dau, northern Vietnam. Around the e-waste recycling workshops, 1,3-phenylene bis(diphenyl phosphate) (PBDPP), bisphenol A bis(diphenyl phosphate) (BPA-BDPP), triphenyl phosphate (TPHP), TBBPA, and PBDEs were dominant among the investigated flame retardants (FRs). The respective concentrations of PBDPP, BPA-BDPP, TPHP, TBBPA and the total PBDEs were 6.6-14000 ng/g-dry, e-waste, tris(methylphenyl) phosphate (TMPP), (2-ethylhexyl)diphenyl phosphate (EHDPP), TPHP, and the total PBDEs were abundantly with respective concentrations of e-waste have been determined to be important factors contributing to the emissions of FRs. The environmental occurrence of emerging FRs, especially o-PFRs, indicates that the alternation of FRs addition in electronic products is shifting in response to domestic and international regulations of PBDEs. The emissions of alternatives from open storage and burning of e-waste might become greater than those of PBDEs in the following years. The presence and environmental effects of alternatives should be regarded as a risk factor along with e-waste recycling.

    In 1972, the USA and Canada agreed to restore the chemical, physical, and biological integrity of the Great Lakes ecosystem under the first Great Lakes Water Quality Agreement. In subsequent amendments, part of the St. Lawrence River at Massena, New York and segments of three tributaries, were designated as an Area of Concern (AOC) due to the effects of polychlorinated biphenyls (PCBs), lead and copper contamination, and habitat degradation and resulting impairment to several beneficial uses. Because sediments have been largely remediated, the present study was initiated to evaluate the current status of the benthic macroinvertebrate (benthos) beneficial use impairment (BUI). Benthic macroinvertebrate communities and sediment toxicity tests using Chironomus dilutus were used to test the hypotheses that community condition and sediment toxicity at AOC sites were not significantly different from those of adjacent reference sites. Grain size was found to be the main driver of community composition and macroinvertebrate assemblages, and bioassessment metrics did not differ significantly between AOC and reference sites of the same sediment class. Median growth of C. dilutus and its survival in three of the four river systems did not differ significantly in sediments from AOC and reference sites. Comparable macroinvertebrate assemblages and general lack of toxicity across most AOC and reference sites suggest that the quality of sediments should not significantly impair benthic macroinvertebrate communities in most sites in the St. Lawrence River AOC.

    In 1972, the governments of Canada and the United States committed to restoring the physical, chemical, and biological integrity of the Laurentian Great Lakes under the Great Lakes Water Quality Agreement. Through this framework, the downstream-most section of Eighteenmile Creek, a tributary to the south shore of Lake Ontario in New York, was designated as an Area of Concern (AOC) because water quality and bed sediments were contaminated by past industrial and municipal discharges, waste disposal, and pesticide usage. Five beneficial use impairments (BUIs) have been identified in the AOC including the degradation of the “benthos”, or the benthic macroinvertebrate community. This investigation used sediment toxicity testing and macroinvertebrate community assessments to determine if the toxicity of bed sediments in the AOC differed from that of an unimpacted reference stream. Results from 10-day toxicity tests indicated that survival and growth of the dipteran Chironomus dilutus and the amphipod Hyalella azteca did not differ significantly between sediments from the AOC and reference area. Analyses of benthic macroinvertebrate community integrity and structure also indicated that macroinvertebrate communities, while impacted across most sites on both streams, were generally similar between the AOC and reference area. Despite these findings, the upstream-most AOC site consistently scored poorly in all analyses, which suggests that localized sediment toxicity may exist in the AOC, even if large scale differences between the AOC and a comparable reference stream are minimal.

    Full Text Available The aim of this research is to garner a full understanding of low energy construction across a variety of sectors in countries throughout the world, and then investigate how the Passiv Haus concept was applied to a Supermarket in Ireland. In order to carry out this investigation, a case study was performed on the energy efficiency and performance of a Tesco store in Tramore. It was found that its electrical cosumption was 24% lower than equivalent stores which were not built to the high specification of the Passiv Haus Standard. As this supermarket is the first of its kind in the world, and with both the SEAl and the European Parliament pushing for this method of construction to be adopted,i11 this standard will most likely in some shape or form become a new building standard in Ireland. This supermarket offers a unique insight into what can be expected in bui lding design and const ruction in this sector if it is undertaken.

    The File-based Filter Farm in the CMS DAQ MarkII The CMS DAQ system will be upgraded after LS1 in order to replace obsolete network equipment, use more homogeneous switching technologies, prepare the ground for future upgrade of the detector front-ends. The experiment parameters for the post-LS1 data taking remain similar to the ones of Run 1: a Level-1 aggregate rate of 100 kHz and an aggregate HLT output bandwidth of up to 2 GB/s. A moderate event-size increase is anticipated from increased pile-up and changes in the detector readout. For the output bandwidth, the figure of 2 GB/s is assumed. The original Filter Farm design has been successfully operated in 2010–2013 and its efficiency and fault tolerance brought to an excellent level. There are, however, a number of disadvantages in that design at the interface between the DAQ data flow and the High-Level Trigger that warrant a careful scrutiny in view of the deployment of DAQ2, after the LS1: The reduction of the number of RU bui...

    Full Text Available This study aimed to characterize the genetic diversity of buriti populations by AFLP (Amplified Fragment LengthPolymorphism markers. The analysis was performed in four populations used by traditional communities in the state of Amazonia(Bom Jesus do Anamã, Lauro Sodré, Santa Luzia do Buiçuzinho, and Esperança II. From each population 30 plants wererandomly selected. To obtain the markers four primer combinations were used. The percentage of polymorphic loci was estimated,the molecular variance among and within populations analyzed and a dendrogram constructed. The primers detected 339 polymorphicloci ranging from 81.1 % to 91.1 % among populations. Analysis of molecular variance attributed 77.18 % to variation within and22.8 % to variation between populations. The dendrogram indicated the formation of two groups, showing that the populations ofBom Jesus do Anamã and Lauro Sodré are genetically most similar and thet the genetic and geographical distances are notcorrelated.

    During the last three decades, breakthroughs in computer technology have made a tremendous impact on optimization. In particular, parallel computing has made it possible to solve larger and computationally more difficult prob­ lems. This volume contains mainly lecture notes from a Nordic Summer School held at the Linkoping Institute of Technology, Sweden in August 1995. In order to make the book more complete, a few authors were invited to contribute chapters that were not part of the course on this first occasion. The purpose of this Nordic course in advanced studies was three-fold. One goal was to introduce the students to the new achievements in a new and very active field, bring them close to world leading researchers, and strengthen their competence in an area with internationally explosive rate of growth. A second goal was to strengthen the bonds between students from different Nordic countries, and to encourage collaboration and joint research ventures over the borders. In this respect, the course bui...

  3. Improving or Disproving Sustainable Development in the Clean Development Mechanism in the Midst of a Financial Crisis?

    Directory of Open Access Journals (Sweden)

    Angus Macdonald

    2010-06-01

    Full Text Available The Clean Development Mechanism (CDM of the Kyoto Protocol is a dual purpose mechanism aiming to reduce carbon emissions and promote sustainable development. However the CDM, as a market mechanism, seems incapable of fulfilling this latter purpose. Bui lding on the dichotomy between market liberalism and sustainable development as identified by D.M. Driesen, this paper argues that the CDM has become a schizophrenic mechanism trying to achieve two mutually exclusive aims. The paper discusses options for improving sustainable development in the CDM, but concludes these options are either impractical or impossible to pursue. The 'development dividend' (as per A. Cosbey, et al is likely to forever be in arrears. The CDM should explicitly acknowledge its sustainable development failings. This brings into question the CDM's very existence. The paper also comments on the effect the financial crisis might have on the carbon market, so crucial for the CDM. The article suggests that the financial crisis will make it even more difficult for the CDM to pursue its sustainable development aim.

    Comments on the original article "Rethinking intractable conflict: The perspective of dynamical systems," by R. R. Vallacher, P. T. Coleman, A. Nowak, and L. Bui-Wrzosinska (see record 2010-08987-003). Vallacher et al presented an intriguing description of dynamical systems theory as applied to the understanding of intractable conflicts ranging from the intrapsychic to the international. It seems clear from the authors' text that the term hysteresis (p. 267) was not their coinage but came from the mathematical history of dynamical systems theory. The concept is fascinating: A single-time measure of an event in a dynamical system is meaningless without knowledge of the whole status of the system, its history, and the current direction of periodic cycles maintained by the system's attractors. Unfortunately, the sound of the term is reminiscent of "hysteria," as if it included notions of feminine unpredictability, periodicity, and emotional catastrophe. Scholars of ancient Greek may find etymological counterweights to this concern, but the use of the word in today's literature runs the risk of intractable conflict with feminist theorists, whose justifiable objection should be intense. I propose the terms bivalence for hysteresis, trivalence when there are three attractors, and so on, up to multivalence for complex systems.

    Benthos (benthic invertebrates) and plankton (zooplankton and phytoplankton) communities were sampled in 2014 at 10 Wisconsin rivers and harbors, including 4 sites in Great Lakes Areas of Concern and 6 less degraded comparison sites with similar physical and chemical characteristics, including climate, latitude, geology, and land use. Previous U.S. Geological Survey sampling was completed in 2012, but because of ongoing sediment remediation at three of the Areas of Concern (AOCs) and unusually hot and dry conditions in many areas during 2012, additional sampling was added in 2014. Comparable sampling methods were used in 2012 and 2014. Benthos were collected by using Hester-Dendy artificial substrate samplers and composite Ponar grab samples of bottom sediment; zooplankton were collected by using tows from depth to the surface with a 63-micrometer mesh plankton net; phytoplankton were collected by using whole water samples composited from set depth intervals. This report describes the study areas and field sampling methods for 2014, and it presents data on taxonomic identification and abundance of benthos and plankton that can serve as a basis for evaluation of related Beneficial Use Impairments (BUIs) at the AOCs. Physical and chemical data were sampled concurrently (specific conductance, temperature, pH, dissolved oxygen, chlorophyll a, total and volatile suspended solids in water samples; particle size and volatile-on-ignition of sediment in benthic grab samples). The results of field quality assurance-quality control are also presented.

    The United States and Canada agreed to restore the chemical, physical, and biological integrity of the Great Lakes ecosystem under the first Great Lakes Water Quality Agreement in 1972. The lowest reach of the Genesee River and the Rochester Embayment on Lake Ontario between Bogus Point and Nine Mile Point, including Braddock Bay, were designated as an Area of Concern (AOC) due to effects of contaminated sediments and physical disturbance on several beneficial uses. Following sediment remedial efforts and with conditions improving in the AOC, the present study was conducted to reevaluate the status of the benthic macroinvertebrate (benthos) beneficial use impairment (BUI). Benthic macroinvertebrate community assessments and 10-day Chironomus dilutus bioassays were used to test the hypotheses that sediments within the AOC were no more toxic than sediments from surrounding reference areas. The study was separated into three discrete systems (Genesee River, Lake Ontario, and Braddock Bay) and non-parametric analyses determined that a multimetric index of benthic macroinvertebrate community integrity was significantly higher at AOC sites compared to reference sites on the Genesee River and in Braddock Bay while AOC and reference sites on Lake Ontario did not differ significantly. Survival and growth of C. dilutus were also similar between AOC and reference sites for each system with the exception of significantly higher growth at reference sites on Lake Ontario. Results generally indicated that the condition of benthos and toxicity of sediment of the Rochester Embayment AOC are similar to or better than that in the surrounding area.

  11. Modeling the Thermal Conductivity of Nanocomposites Using Monte-Carlo Methods and Realistic Nanotube Configurations

    Bui, Khoa; Papavassiliou, Dimitrios

    2012-02-01

    The effective thermal conductivity (Keff) of carbon nanotube (CNT) composites is affected by the thermal boundary resistance (TBR) and by the dispersion pattern and geometry of the CNTs. We have previously modeled CNTs as straight cylinders and found that the TBR between CNTs (TBRCNT-CNT) can suppress Keff at high volume fractions of CNTs [1]. Effective medium theory results assume that the CNTs are in a perfect dispersion state and exclude the TBRCNT-CNT [2]. In this work, we report on the development of an algorithm for generating CNTs with worm-like geometry in 3D, and with different persistence lengths. These worm-like CNTs are then randomly placed in a periodic box representing a realistic state, since the persistence length of a CNT can be obtained from microscopic images. The use of these CNT geometries in conjunction with off-lattice Monte Carlo simulations [1] in order to study the effective thermal properties of nanocomposites will be discussed, as well as the effects of the persistence length on Keff and comparisons to straight cylinder models.
