This article is an attempt to sort out differences between versatile educational activity of student group’s tutor and the absence of clear definition of principal directions on which educational activity is based. The following principal directions of student group’s tutor were identified and systematized: health, collective, studies, leisure, scientific research and public activities. Each of the direction is accompanied by action plan leading to improvement and development of tutor’s educational activity.  

Keywords: the tutor of group of students, educational activity, student’s scientific research activity, students collective, public activity, healthy lifestyle promotion

The article deals with the problem to determine the strength properties of the ballasted clogged sand dunes, including the action vibrodynamic loads. According to the results of laboratory experiments for the first time we obtained the reduction of specific adhesion and angle of internal friction of gravel ballast material on the density and the percentage of blockage of sand dunes under the influence of both static vibrodynamic the action of loads.

The investigated nanocomposites are characterized by more uniform distribution of amorphous and crystal phases. An optimal number of crystallization centers - nanoparticles leads to improve mechanical properties of polyethylenes. Introduction of nanofillers into a polymer matrix leads to the formation of cryptocrystalline supermolecular structure by reducing of the thermodynamic threshold of crystallization.

At the end of 2012 – the middle of 2013 pilot questioning among RGSU students was carried out. In total more than 330 students of the first and second courses were interrogated. The work purpose – measurement of dynamics of an emotional component of group installations in relation to a political order. The emotional component of group political installation was measured on technology of semantic differential. It was offered to estimate to respondents on 20 bimodal scales four types political about. Two ideal – ideally positive and ideally negative orders. And two real – local and central. In the linear approximation calculated levels of emotional perception of the political order in the vicinity of the averaged image of the real image of the ideal order to constructs used in the space of features. Perception of an order at the end of 2012 in Region: -0,21892, in Russia: -0,24154 . To the middle of 2013 level of perception decreased: in Region: -0,59429, in Russia: -0,43879 . For the considered period level of a relative deprivation also was analysed: in 2012 level is equal 0,523 and in 2013 made 0,555. Thus, to the middle of 2013 there is a small increase in level of a deprivation that correlates with deterioration of perception of a political order among youth.

This article describes an algorithm for finding the linear functional quality that describes the order of preference on a set of technical systems. The basic idea, which implements the algorithm is to break the complex solutions of the preference (for many variables) into a number of simple solutions (in pairs of variables), followed by a formal synthesis of the overall solution.

Keywords: The algorithm for finding the linear functional quality of the order of preference on a set of technical systems, formal synthesis, the numerical value of the degree of competence of the individual experts

The paper presents national practice calculations of economic impacts used in environmental management. Direct and indirect cost economic impact assessment was considered. Particular attention is given to approaches of economic valuation of natural resources.

  Today in Russia, unfortunately, the science is one of professions, is far not so popular, as the lawyer, the financier or the programmer. At the same time competitiveness of modern economy depends both on separate scientific and technological achievements, and on technologies of management of an innovation in the various countries. The review of experiences of innovative development is presented in this article abroad in such countries, as the USA, China, Finland and South Korea. Innovative development of these countries conducting economically will be rather interesting to CIS countries where need of such development is an essential task.

Keywords: science, innovative system, innovative development, hi-tech production

This paper presents key capital structure determinants of construction companies and their impact on fund raising and financing mix formation in accordance with the conditions of construction activity. It was found that profitability and tangibility have a positive effect on leverage, risk - the negative and the effect of company size, assets growth rate and taxes is ambiguous.

Keywords: capital structure determinants, profitability, risk, taxes, tangibility, construction companies

The article describes the main problems of circuit simulation. The problem of solving ill-conditioned systems of linear algebraic equations (SLAE) of large dimension. The modified algorithm is a linear algebraic solutions. Described a hybrid evolutionary algorithm for solving linear systems based on the proposed modified method. The results of the pilot study and comparison of the algorithm with the algorithms based on the traditional methods for solving linear algebraic equation, which confirm the advantages of the hybrid evolutionary algorithm.

The article describes the methods of forming the program of technical and economic feasibility of reconstruction. The program is based on the technical and economic calculations which justify the need for its development. It is important to take into account the technical and economic indices which provide a minimal amount of construction works. During the development of technical and economic parameters, it is necessary to take into account the organization of construction, the terms of energy saving, heating, water supply, drainage and industrial waste water, human resources, the environment, the effectiveness of capital investments. All questions are considered for the perspective of the development of science and technology.

Keywords: site renovation, technical-and-economic indexes
