    In 2012 the total volume of coal mining in the Kuzbass was about 200 million tons, including 116 million tons (60.3%) produced open way, Figure 1. In 2014, it was produced more than 203 million tons of coal. In addition, there is no reason to believe that in the near future volume of coal will decline. Accordingly, the volume of wastewater discharged by enterprises will increase. So, from 2006 to 2009 there was an increase of polluted water discharge coal mines from 217 to 245 million m3. Therefore, the problem of water pollution mines governmental waters and career is very important

    Chronic venous diseases are one of the urgent problems of modern medicine. Recent studies have shown high significance of endothelial dysfunction (ED) and oxidative stress in their pathogenesis. For the correction of the occurring changes, drugs of the flavonoid group, particularly diosmin and hesperidin, are currently use

    The thermoelectric and galvanomagnetic properties of nanometer structured epitaxial films and foliated layers based on bismuth and antimony chalcogenides were investigated, and an increase in the figure of merit Z up to 3.85 × 10-3 K-1 was observed in the Bi0.5Sb1.5Te3 films over the temperature range of 180–200 K. It is shown that an increase in the Seebeck coefficient and the change in the slope on temperature, associated with changes in the effective scattering parameter of charge carriers and strong anisotropy of scattering in the films, lead to enhance power factor due to the growth of the effective mass of the density of states. These features are consistent with the results of research of oscillation effects in strong magnetic fields at low temperatures and research of Raman scattering at normal and high pressures in the foliated layers of solid solutions (Bi, Sb)2(Te, Se)3, in which the topological Dirac surface states were observed. The unique properties of topological surface states in the investigated films and layers make topological insulators promising material for innovation nanostructured thermoelectrics

    Β© 2016, ASERS Publishing House. All rights reserved.This article is devoted to the study of social and ecological risks in the Republic of Tatarstan and the influence of the activity of chemical city-forming enterprises on the ecological situation. The example of single-industry towns shows that the unfavorable ecological setting is a consequence of the increase in production dangerous to public health and the environment, which leads to a decrease in the quality of life, the outflow of the population, increased mortality, and depopulation. The analysis of the situation in the sphere of ecology and nature management shows that in recent years the Republic of Tatarstan has accumulated a number of serious problems that do not allow fully achieving the desired quality of the environment and ensuring the protection of natural resources and their sustainable use and reproduction. The state of the environment in many municipalities of the republic continues to be unfavorable. The level of air and water pollution significantly exceeds the established standards, and there is the pollution, depletion and degradation of soil and a constant increase in the volumes of production and consumption waste. Due to excessive anthropogenic pressures, landscapes are being changed, and there is a growing problem of preserving the biological diversity of plant and animal communities
