This article addresses options for building advanced of resistive voltage dividers (attenuator), providing a reduction in a given number of once input voltage in a wide range of operating frequencies. To correct the frequency error in the AT parasitic capacitance the load is proposed modified scheme with the special frequency attenuator correction, which allows for one to two orders extend the range of working frequencies the AT and increase performance.

High purity ultrafine aluminum nitride is produced by gas-phase approach, however there is an issue to divide AlF3 and AlN at the final step of synthesis. Recently, the problem is solved by sublimation of aluminum trifluoride in vacuum, but due to high temperatures aluminum nitride particles agglomerate into chunks with dimension about 8 μm, hence the new alternate methods of separation is in a great interest. Flotation in organic environment is considered to divide aluminum trifluoride and aluminum nitride. The process of AlN and AlF3 interaction with organic and element-organic matters was investigated and the following conclusions were made: there is agglomeration and sedimentation stability of AlN and AlF3 in organic environments and flotation possibility was experimentally proved, hence, flotation after special treatment is a possible approach to divide powders of aluminum trifluoride and nitride.

The article considers the problem of maximum flow of minimum cost finding in fuzzy dynamic transportation network. The relevance of the problem is in its wide practical application on the rail, air, sea and other roads in finding of routes of minimum cost. The feature of the problem statement is that fuzzy nature of the network parameters, such as arc capacities and costs is taken into account. It allows us to make decisions more sensitive to environmental changes. The dependence of network parameters from flow departure is also considered, that allows to introduce the notion "dynamic" network as opposed to "stationary-dynamic", examined in the literature. The algorithm for solving the described problem in fuzzy conditions is proposed. To illustrate the algorithm a numerical example is presented.

Keywords: dynamic network, maximum flow of minimum cost, fuzzy numbers, arc capacity, transit time

The titanium dioxide synthesized by an electrochemical method is a perspective material for use in solar elements and catalysts of cleaning of water and air environments. Regularities of electrochemical synthesis of titanium dioxide in glycerin dilute solutions (1:1) in the presence of ammonium fluoride at 2-14 V are investigated. Mathematical scheduling of synthesis process according to plans of first order with use of the complete three-factorial experiment is carried out, the adequate regression equations for formation processes of a titanium dioxide in the field of potentials 8-14 V are received. The electron microscopy method proved porosity of synthesizable layers of titanium dioxide. Water content influence in electrolyte on the speed of electrochemical process and potential size influence on titanium dioxide materials yield is established. It is shown that under the chosen electrolysis conditions electrochemical process is accompanied by the considerable chemical disolution of a titanium. Electrochemical processes in water containing glycerin are investigated by a cyclic voltammetry method. It is established that at electrochemical oxidation of Ti in water containing glycerin (1:1) porous TiO2 with a materials yield no more than 25% is formed.

Research presented the analysis of the cognitive components of the perception of the political order based on the pilot questioning in Vladikavkaz in 2012. 47 respondents took part in questioning. The questionnaire included a subjective assessment of the following levels the participation in political processes; the emotional involvement into them; discussion of the these processes; economic welfare; social protection; life prospects. In addition, the questionnaire included questions about the degree of religiosity, and also the general questions characterizing the respondent (a sex, age, a nationality, level of parents education). To assess the level of deprivation used the subjective opinion of respondents on the levels of economic welfare and social protection, assessment of prospects in life, and also the degree of involvement in various political processes. Received, the level of involvement of young people in Vladikavkaz in the political processes in society - 1.28, the level of emotional involvement - 1.91. Average consistent level comments political processes in the family - 2.15.  The level of economic well-being and average level of social protection of students: 2.27 and 2.34. Assessment of prospects in life is average - 2.96. It was revealed in 2012, there is a low level of participation in political life with a low level of involvement in the political process. Some parameters of relative deprivation is average, and it is expected that this component will not lead to the formation of political tension.

Researches based on results of the questioning among the students of Grozny (GGNI), conducted in 2011 - 2012. Over the entire study period, 525 people were interviewed. The questionnaire consisted of questions focused at identifying the subjective opinions on own relation of respondents to a political order, and also questions opening level of a group relative deprivation. The received results of a cognitive component were processed by a method of the statistical analysis in software package SPSS. It is revealed, increase the level of relative deprivation among a group of students, which may indicate an increase in the level of political tension. Detected, reducing the level of emotional involvement in the political life of the Republic, which is exacerbated by increased levels of alienation from the political process. In the identification of situations among student of Grozny need to direct efforts local government at ending the fall of the level of emotional involvement, as well as to control the level of relative deprivation with fixing it to reach the middle level.
