ENVIROMENTAL AND ECONOMIC RISKS IN THE FIELD OF MODERN POWER INDUSTRY
DescriptionThe article highlights the main factors influencing the modernization of the electric power industry in Russia, that can positively influence the process of environmental upgrading companies of this sector, improve competitiveness and environmental performance. It has identified the main risks and uncertainties in the electricity sector. We have selected the most serious of them. As one of the most urgent tasks of the present stage of development of natural resources and technological standards in the electricity sector, we have highlighted the development of criteria for inclusion of technology to the "best available technology" category

Description
In the article we have studied the technology of obtaining a biomass of oil oxidizing microorganisms in a nutrient medium containing vegetable oil as the sole source of carbon and energy. In vitro and in soil experiment we have confirmed the effectiveness of the resulting biomass at work on bioremediation of oil contaminated sites. It is shown that the use of vegetable oil during culturing allows obtaining the same amount of biomass and carbohydrate raw materials, but the efficiency of its use is 20% higher, in average

01.00.00 Physical-mathematical sciences
DescriptionMicro and nanofluidics are the new multidisciplinary sciences. One of the tasks of which is creation and management of flow of fluid in the thin channels size of a few nano- or micrometer which exposed the external electric field, where the walls are the ion exchange membrane. Electroosmosis (electroconvection) plays an important role in these tasks. A large number of articless were devoted to electroosmosis. One of the first, Dukhin S.S., Mishchuk N.A. and Rubinstein I. gave a theoretical explanation of the overlimiting current by electroosmosis. They used two-dimensional Stokes equation to calculate the flow of the electrolyte, and one-dimensional equations of Nernst-Planck and Poisson to calculate the electric power. These researches have multiple limitations because of the computational complexity the mathematical simulation. Thus, there is an actual problem of the asymptotic solution of boundary value problems for the two-dimensional systems of equations of NernstPlanck and Poisson without these restrictions. These researches we derived in simplified models of electroosmosis in galvanic dynamical mode using the decomposition method. We have created a hierarchical system of two-dimensional mathematical models of ion transport of salt and electroosmosis in micro- and nanochannels formed by selective ion-exchange membranes

ELECTRICAL CONDUCTIVITY OF IONEXCHANGE MEMBRANES IN SOLUTIONS CONTAINING CARBOXYLIC ACIDS
DescriptionThe article presents the experimental results of the study of the concentration dependence of the electrical conductivity of heterogeneous ion-exchange membranes that are in contact with solutions of weak electrolytes - carboxylic acids. It is shown that in this case the membrane conductivity is higher than the conductivity of the solution, wherein the conductivity of cation exchange membranes substantially greater (by an order of magnitude) than the conductivity of anion exchange membranes. This fact must be considered when designing the actual electrodialysis processes of processing solutions containing organic ions. The work identified the need to develop modern ideas about transport and the structural organization of ion-exchange materials, to describe the structure of the ion-exchange membranes that are in contact with weak electrolytes solutions

Description
The stability of strongly basic anion-exchange membranes MA-41-2P (JSC "Schekino-Nitrogen", Russia) and AMX (Tokuyama Soda, Japan) under intensive current regimes was investigated in the current study. The process of water molecules dissociation at current densities above the limiting one in 0.01 M sodium chloride solution was studied in detail. The length of the electroconvective instability at the membrane / solution interface at currents exceeding the limiting current was measured by laser interferometry

LANGUAGE IDENTITY THROUGH THE PRISM OF POLITICAL NEWSPAPER COMMUNICATION
10.00.00 Philological sciences
DescriptionPolitical newspaper communication has been researched and it is pointed out that the communication between communicators is carried out at the inner mental dialogical level. Questions of text comprehension are analyzed. It is emphasized that behind the political newspaper text there is a language system and without knowledge of this system communication based on text activity is impossible
