National University of Uzbekistan is the oldest and largest university of Uzbekistan; it has 13 schools. The university was founded in 1918 as Turkestan People's University, with 1,200 students; in 1920 it was reorganized as Turkestan State University , and in July 1923 it was renamed the First Central Asian State University , a name it retained through the end of the 1950s. In 1960 the name was changed to the V.I. Lenin Tashkent State University . With the independence of Uzbekistan it became the National University of Uzbekistan.During World War II many academics were removed from cities in the western USSR to Central Asia, and Tashkent, along with Alma-Ata, was favored for its European-style infrastructure and the presence of a significant number of Russian-speakers; a group of professors from Moscow protested being transferred from Tashkent to Ashgabat.

Global geographic disparities in stroke mortality rates are substantial. In the US alone, higher stroke mortality rates are reported in the Southeast part particularly along the coastline while lower rates have been observed in the Mountain region. The phenomenon has been called the "stroke belt" Although many theories have attempted to explain such nonrandom distribution of stroke mortality rates, no conclusive explanations have been drawn so far. I hypothesize that this nonrandom stroke distribution is related to regional differences in individual levels of erythropoietin (EPO), a hormone, which production depends on the tissue hypoxia due to variation in altitude. If successful, future studies based on this hypothesis may open up new avenues for treatment of such an important health issue as stroke. More importantly, future studies based on this theory may shed the lights on the mechanism of stroke as well as other diseases which have nonrandom geographic distribution not only in the US but also internationally. © 2012 Elsevier Ltd.

Bavarian alpinist and researcher Gottfried Merzbacher discovered an ice-dammed lake in 1903 while trying to reach the mysterious Khan Tengri peak, located where Kyrgyzstan, Kazakhstan, and China meet. This lake, which was later named after him, is currently two lakes in the Northern Inylchek Valley. At an altitude of 3300 m and 3400 m above sea level (a.s.l.), these two lakes are known as Lower Lake Merzbacher and Upper Lake Merzbacher. Lower Lake Merzbacher is dammed by the Southern Inylchek Glacier and has had regular outbursts since the beginning of the 20th century. While these outbursts have been sporadically documented since 1902, neither the documentation nor the reliability of the reports has been consistent. Knowledge of many of the floods is known only from the oral or written contributions of mountaineers, glaciologists, and frontier guards. A small number of floods were measured at gauging stations downstream. Since it was not always recognized that these floods were the results of glacier lake outbursts, not many papers on this subject have been published in German, English or Russian journals. There were about 40 outbursts reported between 1902 and 2004, but only a few of them were eye witnessed. A number of geoscientific expeditions investigated glacier retreat and the mechanism of the (lower) lake's outburst through an englacial piping system of the Southern Inylchek Glacier. As the Inylchek River flows into the Tarim Basin, the flood waves endanger not only Kyrgyzstan but also China. This paper gives a short overview on the mechanism, magnitude, repetition rate and timing of Lake Merzbacher's outbursts. Of particular interest is the discovery that the outbursts have shifted statistically significantly, namely from September/October in the first half of the century to July/August in last few decades. It is presumed that this is due to the climate change. Future research on the impact of climate change on the Upper Inylchek Valley is supported by the Global Change Observatory "Gottfried Merzbacher", which opened in 2009 and was jointly planned by the Central Institute of Applied Geosciences (CAIAG, Bishkek, Kyrgyz Republic) and the German Research Center Potsdam (GeoForschungsZentrum - GFZ-Potsdam, Germany). The installation of ablation gauges, planned ice core drilling, and hydrometeorologic and seismologic stations will make it possible to assess the climatic and neotectonic development of the Central Tien Shan in general and to calculate the mass balance and quantification of the partly retreating Southern Inylchek Glacier in particular. This article "A Century of Investigations on Outbursts of the Ice-Dammed Lake Merzbacher" briefly summarizes observations and research conducted since 1903 and also documents the lake's regular outbursts.

Te abilities of Pseudomonas extremorientalis TSAU20 and P. chlororaphis TSAU13 to colonise and survive in the rhizosphere of common bean under saline conditions were studied. Four salinity levels (5.0, 7.5, 10.0, and 12.5 dS/m) were maintained in the gnotobiotic system using NaCl salt. Results showed that with increasing salt content root-tip colonization of both bacterial strains was reduced. Both bacterial treatments used in the study increased root and/or shoot length compared to non treated plants at each NaCl concentration tested, whereas shoot growth was not stimulated at high saline condition (12.5 dS/m). In conclusion, the results of this study indicated that P. extremorientalis TSAU20 and P. chlororaphis TSAU 13 have the ability to survive in ecologically stressed conditions, such as saline and nitrogen deficient soils, and may positively effect on plant growth of bean. High salinity inhibited their colonisation in the rhizosphere of bean and thus their stimulatory effect on plants was also reduced. Source

We consider fertile three-state “hard core” models with the activity parameter λ > 0 on an order-three Cayley tree. It is known that there exist four types of such models: in two of them, the translation-invariant Gibbs measure is unique for λ > 0, and in the other two, a value λcr is found such that there exist only three translation-invariant Gibbs measures for λ > λcr and a single translation-invariant Gibbs measure for λ ≤ λcr. © 2015, Pleiades Publishing, Ltd.

The list of 240 eclipsing variables with the light equation (LITE effect) has been compiled. Some characteristics of multiple systems have been determined assuming that those stars may contain extra components. Quantity distributions have been obtained for Close Binary Systems (CBSs) with LITE effect and for those without it. The observed excess of short period stars (<0.3 days) is shown to be realistic. The eccentricities of Long Periodic Orbits (LPOs) have a parabolic distribution with a weak maximum at e = 0.28. The ratios of LPO to CBS periods cannot be considered to be random. The dependence of those values on LPO periods has been revealed. The distributions of periods and semimajor axes of LPOs are shown to have maxima at P3 = 32 yrs and a = 16 AU, respectively. The latter distribution can be described by the Gaussian function. Approximately 85% of tertiary companions in stellar systems have a mass which is half as much as the total CBS mass. Except for one CBS (RR Lyn), all multiple systems of the obtained list are dynamically stable configurations. The possibilities to detect tertiary companions using speckle interferometry observations and proper motions of CBSs, as well as by extra light contribution when analyzing light curves and radial velocity changes of the CBS center of mass are discussed. Other causes are considered which may be a reason for the LITE effect, such as the mass exchange in CBSs and the influence of the magnetic field of components. Certain difficulties may arise when interpreting the LITE effect caused by the magnetic field of components. The most promising research directions in detecting tertiary companions in CBSs with the LITE effect are suggested. © 2010 Allerton Press, Inc. Source
