Seed damage has a negative impact on the subsequent development of the plant, its yield, and generally on the economic efficiency of grain production. Main percentage of the grains injury occurs in the post-harvest processes, particularly in the grain cleaning. One way of solving this aim is reducing of macro and micro damage of seeds by using   of the   new polymeric materials. Researches have been conducted to reduce the micro and macro of injury barley seeds (feed material) through the use of  new sieves made of polymeric materials UHMW PE  for agricultural machinery.

Keywords: polymeric materials, micro and macro damage, reducing injury of the seeds

The article analyzes one of the basic concepts of a rational economy – the marginal utility. It is shown that the models accurately describe the behavior of the individual, derived from human psychophysics.

The paper reports on dynamical model of optimal biological resource exploitation with corruption. Particularly, it is allowed a fish quota increase after paid a bribe. The research has been realized with the sustainable development conception by the Pontryagin's maximum principle. A time moment, where the bribe is profitable, is considered. Fight corruption methods are presented.

Keywords: Mathematical model, optimal exploitation, corruption

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.

Keywords: a political tension, deprivation, group installation in relation to a political order, cognitive component, questionnaire, the descriptive statistics

This paper describes application of different criteria for estimating parameters of traffic simulation. For comparison following methods were used: statistical methods for comparison of a flow and speed in control points of a network - analysis of variance (ANOVA), Theil's U-statistics; relationships between flow, density and speed; relationships between trip time and stop time with using two-fluid models of traffic flow. For this aim we also used concept of meta-model. In order to implement this method we need on the first step to create separately relationship between traffic flow parameters for observation and simulation data and then to estimate combined model. The paper included results of calculation  

Keywords: validation, traffic, simulation, flow, speed

  The issues of improvement of state cadastral valuation of land plots, which are occupied by industrial enterprises, are investigated in the article «About the development of the methodology of calculating the cadastral value of the land plots of large industrial enterprises». The analysis of the possibilities of application of methods of individual assessment for the valuation of such land plots and the delineation of the concepts of cadastral and market value were made.

One of the main parametrs for traffic engeneering of pedestrians is pedestrian's speed. We don't have information about influence week's day, day's time, an ain of moving for pedestrian's speed. There'are results of researches in the article about alone pedestrian's speed, about speed of pedestrian's groups. A lot of pedestrian's groups have two or three persons. A key information about pedestrian's speed brought by mesurements distances and time of mouving. Those mesurements were during the each day of week from 08:00 to 20:00. Pedestrian's speed depends on size of pedestrian's group firstly, an aim of walking secondly

"The paper proposes a method of use of the accumulated surplus of solar water heating installation, the major element of which is the solar collector for heating of greenhouses. The heat energy, which was preserved in the battery for the summer months, can be used for heating of greenhouses in the autumn and winter months. The proposed method will significantly increase the efficiency of the solar collector and reduce the term of recoupment. This development will be relevant for the individual dwelling houses, with garden plots sufficient to build greenhouses there. The use of ""Energy - Effective"" greenhouses combined with solar water heating unit, significantly reduces the cost of electricity and heating. The use of low-grade thermal energy from the sun and soil is the main direction of development of energy-saving technology of housing and communal services. "

Keywords: solar collector, energy efficiency, energy-saving, low-potential energy, alternative heat source.

In article it is shown that the state in the functions, first of all on rendering of public services, becomes a direct factor of production and in this part turns into an integrated component of limited production resources. At the same time, inconsistent decrease in efficiency of expenses of the consolidated budget of the Russian Federation on nation-wide questions and on national economy is observed.

  The article is devoted to the problem of the research of geopolitical processes on the world regions’ scale under present-day conditions. The article substantiates the necessity of their analysis with the help of the cognitive approach as an effective means of cognition of the interconnections and interrelationships within the complicated systems. With that aim in view the specifics and the stages of the cognitive modeling are given thorough analysis in the article. This type of modeling is adapted to the analysis of geopolitical dynamics on the regional/sub regional level taking into consideration its aptitudes to make prognostic scenarios of the development of the situation. The possibilities of the cognitive modeling of geopolitical processes are illustrated on the example of the situation in three sub regions constituting one (big) the Black Sea – Caspian region.
