General Relativity and Gravitation | Year: 2016

The structure of an interior dipole magnetic field of neutron stars in f(R) gravity is considered. For this purpose, the perturbative approaches are used when both the deviations from general relativity and the deformations of spherically symmetric configurations associated with the presence of the magnetic field are assumed to be small. Solutions are constructed which describe relativistic, spherically symmetric configurations consisting of a gravitating magnetized perfect fluid modeled by a realistic equation of state. Comparing configurations from general relativity and modified gravity, we reveal possible differences in the structure of the magnetic field which occur in considering neutron stars in modified gravity. © 2016, Springer Science+Business Media New York.

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. © 2009 Elsevier B.V.

On 24 July 2008, a glacier lake outburst flood (GLOF) occurred at the western (w-) Zyndan glacier lake in the Tong District of Ysyk-K¶l 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. © 2010 Author(s).

A botanical and ecological study of locally collected material showed that wheat landraces are represented in a very wide variety of ecological and morphological forms scattered in different areas of Kyrgyzstan. In total, 60 subspecies of spring wheat belonging to 6 species are found in Kyrgyzstan. There are several ecological groups on the territory of Kyrgyzstan. The most common ecotypes, rigidum and subrigidum, are related to Iranian-Asian subspecies. At present, about 80 varieties of the Kyrgyz wheat of Kazakh breeding and breeding of the CIS countries are successfully passing the state variety test. On the basis of analyses of productivity and quality of winter and spring wheat, the following varieties were identified: Dordoi 16, Mereke 70, Kiyal (st), Suleiman, Kasiet, and Araket. Up to 35 varieties of winter soft wheat and up to 12 varieties of spring soft wheat bred domestically and abroad are tested annually and recommended for cultivation in different areas of Kyrgyzstan. © 2013 Pleiades Publishing, Ltd.

A fundamental problem in mathematics is to decide whether such smooth, physically reasonable solutions exist for the Navier-Stokes equations. We restrict attention here to incompressible fluids filling all of Rn. The Cauchy problem for the nD Navier-Stokes equations is reduced to the integral equations of Volterra and Volterra-Abel, investigation of which, allows us to solve positively question on uniqueness and smoothness of the solution. © 2016 Pushpa Publishing House, Allahabad, India.

In this work we consider Volterra linear integral equation of the third kind in the case when the external known function reduces to zero in the internal point of integration interval. The solution of it exists in the space of continuous functions. The numerical solution is constructed and its convergence to the solution of the initial equation is proved. © Springer International Publishing Switzerland 2016.

Since the independence of Kyrgyzstan in 1991 and the subsequent dissolution of the collective/state farm system, the drinking water supply system in rural communities has been deteriorating much faster than in urban areas. This paper demonstrates the actual problems of the drinking water supply system in Kara-Suu, a small village in the Naryn Oblast. Much of the water supply infrastructure is out of operation and many villagers are forced to set up private solutions. Due to the poverty of the villagers, the local administration is unable to maintain the infrastructure and to provide a reliable water supply. This in turn causes their unwillingness to pay the water fee. Nevertheless, an increased responsibility of all stakeholders to manage the local water supply system is crucial. It is necessary to raise the awareness of all stakeholders, to animate them for more private dedication, and to reduce mistrust and corruption. © 2014, Springer-Verlag Berlin Heidelberg.

This study is devoted to investigation of plasto-viscoelastic properties of soluble humate hydrogels with the aqueous medium pH 6–7, obtained by neutralizing relevant alkaline extracts by various acid solutions, and insoluble humates of polyvalent metals. The comparative study of the structure formation processes in gels of soluble sodium and potassium humates with pH 6–7, containing a mineral salt, shows that the dispersed medium composition affects plasto-viscoelastic properties of the coagulation medium. When potassium humates contain KNO3 salts, the CCS value compared to a gel without KNO3 reduces from 17% to 13.6% of the dispersed phase, thereby enhancing the structure. In potassium humates, the NaNO3 salt has an opposite action, i.e., it deteriorates the structure formation properties; compared to a gel without NaNO3 the CCS increases from 10% to 14% of the dispersed phase, reducing the strength of the coagulation structure. The produced samples of insoluble iron (III) humates are the products of incomplete substitution of the Na+ ion from the acid groups of the soluble form of humic acids. The structure formation capacity of the hydrogel with the H + form of humic acids is expressed much weaker compared to hydogels of iron humates. This is demonstrated by the high CCS value (22% of the dispersed phase) and the low values of the strength parameters at CCS. © 2014 by Begell House, Inc.
