INSTITUTIONAL INFRASTRUCTURE: ESSENCE AND CONTENT
DescriptionThe article discusses the concept of "institutional infrastructure" and clarifies its essential content in relation to market cars. In terms of the industry market the main purpose of the institutional infrastructure is achieving the maximum economic benefit within limited resources. The main tasks that need to be solved in order to achieve this goal were formulated. We have developed and proved structurally-logical chart of the elements of the institutional infrastructure. The content of the institutional infrastructure of the car are presented and justified. The analysis condition of the car market’s institutional infrastructure showed the problems associated with the state of institutions which have an impact on the functioning of the car market. Measures to stimulate the car market does not cover entire sector as a whole, and imported institutions do not give the expected effect because of inconsistency formal and informal elements of the institutional infrastructure. Presented assessment of the institutional infrastructure of the car market confirms the dependence of the state of the industry market cars from institutional infrastructure. Only reforming the institutions at all levels of the industry, from production to car sales can have a positive effect on the industry. Changes in the institutional infrastructure should be focused on improving the competitiveness, stability and independence from external factors

Description
The main tendencies of the development of forestry in the Russian Federation under the implementation of the Forest Code of 2006 are discovered, the goals of forming the institutional environment for forests use, conservation, protection and reproduction at the present stage are defined. The activities in the field of conservation, protection and reproduction of forests in the country in the period from 2007 to 2013 are characterized by a decrease in the volume of work and activities. A steady upward trend in the loss of forest resources from forest fires was outlined. The state policy of the Russian Federation in the area of use, conservation, protection and reproduction of forests is aimed at conservation and augmentation of forests, maximum satisfaction of the needs for high quality products and useful properties of forests. The achievements of stated objectives were provided by solving of a number of tasks, including the increase in efficiency of the forest sector management and intensification of the use and reproduction of forests, which have the priority meaning. The authors determined the institutional model of public-private partnership in the forest sector of the Russian economy recognizing the need to develop flexible institutions for interaction between government and business in the use, conservation, protection and reproduction of forests as an integral part of intensive economic model. The article proposes a conceptual scheme of efficiency assessment for investment projects in forest development and target functions for data subjects of investment projects: the federation, the region, the business and local community

PHILOSOPHICAL REASONING OF THE CONCEPT OF THE GAME AND ITS USAGE IN NON-PLAYING CONTEXT
DescriptionIt is interesting for interdisciplinary understanding of game phenomena, how the concept of the game discourse can operate in different non-playing contexts. Researching of game concept allows tracing the figurative conceptualization knowledge of this universal phenomenon. The author uses a lot of examples to prove that game phenomenon represents itself in a language and has been reflected in the mind of people. It is shown, that lingvo-culturological concept of the game has more productive metaphorical rethinking. We single out the most important characteristics of game, explain some imaginations about gaming, explicate dominant sense of game freedom, its choice, imitation, dynamic and emotional stress, agonistic, risk, unpredictability and others attribute the symptoms. Represented contexts of usage also illustrate communicative and social components of gaming behavior. Dominant meanings, key ideas, that unite viewed image, actualize basic principles that are typical for the game phenomenon in common, and the specific characteristics of different types of games (sport, children, gambling, theater, computer, etc.)

THEORETICAL FOUNDATIONS OF FORMATION OF ENTREPRENEURIAL CLUSTER
DescriptionThis article investigates the development of entrepreneurial cluster set direction to support the creation of innovation clusters in Russia. In the face of increasing international competition, one of the most effective ways of development of small and medium-sized enterprises in the field of innovation is their clustering. We have discussed foreign experience of studying cluster initiatives and events on social development of the regions in the context of sociological knowledge about clusters. We have revealed the meaning of an innovation cluster and the difference between business and innovation clusters. The analysis has shown that a key advantage of the business cluster in relation to the network is the participation of state authorities, as well as functional and territorial factor. On the basis of the author's research we have highlighted a number of problems which solution has been carried out through the creation of business clusters

ANTHROPOGENIC DISTURBANCE RESEARCH OF NATURAL ENVIRONMENT IN THE CONDITIONS OF SANDPITS
06.00.00 Agricultural sciences
DescriptionIn this article, an anthropogenic influence on natural ecosystem such as an excavation of sand is discussed. Investigations were done in Kuyar Forest District of the Mari El Republic on a sandpit. The adjacent plot of natural forest was taken as a control. For evaluation the degree of environment transformation as a result of sand excavation several indicators were used. As indicators of physical soil degradation - thickness of organogenic horizon and soil density; for assessment a chemical degradation – content of main nutrients and humus; as an indicator of biological degradation – the level of active microbial biomass. Besides, a potential phytotoxicity was estimated. The study proved: physical and chemical parameters corresponded with the fourth degree of soil degradation, at the same time, biological parameters approximated to parameters of soil from natural territory

PYROLYSIS OF FOREST RESIDUES IN THE CHARCOAL FURNACE
DescriptionThe article presents the modernization option of the forest residue furnace that allows speeding up the drying process by boosting it. The dependencies, reflecting the influence of the temperature of the drying process on the heat losses of the furnace and the effect of the load and the moisture content of the feedstock to the fuel consumption for the entire drying process, are presented in the article

HYDRAULIC DEVICES FOR HYDROSYSTEM TAILRACE PROTECTION
DescriptionBased on the Karman vortex theory, the calculated dependences for velocity induced by profile action in the flow, lifting force and drag force, acting on the profile, are determined. Calculations, performed in MathCAD, allowed, for the given up-stream velocity, to calculate height of mid-section of the bed-formation profile, width of the profile along the chord, span of the profile, angle of attack, velocity of the induced flow. For the calculated profile parameters, the velocity circulation value, drag force and lifting force are determined. As the bed-formation profiles, it is recommended to use flat plates, frame constructions with transverse ribs in the form of arch, fish-like symmetric or slightly curved profiles. Ways of the profile installation in the flow, depending on the angle of attack, are evaluated: three versions - for symmetric profiles, and six versions - for asymmetric profiles. Diagram of the device for the hydrosystem tailrace protection against erosion is developed on the basis of submerged NACA 0302 profile or profile of Zhukovsky, made of flexible materials, including profiles, system of supporting and regulating ropes, and shore or bottom supports. This design is mobile, intended for the periodic regulation of sediment yield
