INTRODUCTION FEATURES OF RED OAK (QUÉRCUS RÚBRA) IN MARI EL REPUBLIC
06.00.00 Agricultural sciences
DescriptionThe research purpose was estimate of the red oak growing suitability in Mari El Republic. To achieve this goal we investigated experienced 44-year-old red oak plantation at the Botanical garden-Institute, determined acorns morphological characteristics of red and English oaks and seedlings grown from them. The evaluation of red oak plantings identified excess of average height and tree diameter in comparison with English oak, but the sanitary condition of both oaks forests was weakened due to the influence of the complex of unfavorable factors. Morphological acorns evaluation showed that the shape factor of acorns of English oak is equal to 1.64, while the red oak is 1.1. Biometrics parameters of red oak bareroote seedlings in the field were higher than English oak bareroote seedlings. In greenhouse biometric parameters of red oak container seedlings had not excess. According to this research, red oak is recommended for use in landscape construction in Mari El Republic

THEORETICAL RESEARCH OF AN ENERGYSUPPLYING COMPLEX FOR APIARY BASED ON HYBRID SOLAR PLANT
DescriptionIn the article, we present a simulation mathematical model of an energy-supplying complex of apiary based on hybrid solar plant that establishes the relationship between the design and the operating parameters of the complex with when having conducive winter maintenance of bees. Modeling methodology involves the selection into a mathematical model of multiple levels: level of processes, that directly related with changing of climate parameters inside the hive depending on external factors, level of processes of functioning of the individual components in the complex, which are not directly connected with the processes of changing of climate parameters inside the hive, however, are necessary to ensure favorable conditions for wintering of bees. We have conducted the simulation of the complex based on hybrid solar plant for conditions: the location of apiary in the Republic of Mari El (building for placement of bees for 250 bee colonies, the number of photovoltaic modules – 10, wind power plant area – 18 m2 , the capacity of the battery – 50 A·h, the heat accumulator capacity – 3 m3 , the time interval – from 14 October to 14 April). As a result of simulation obtained graphs of the changing the thermal battery coolant temperature, the voltage at the battery terminals, the power wind turbine and PV modules, the electrical energy consumption

THE RESEARCH OF PARAMETERS OF WOODEN CHIP COLORING
DescriptionThis work presents main kinds of colourants and methods of painting wood particles. Based on wood structure analysis, it was revealed that hard wood, possessing tracheides and vessels as conducting elements, have the optimal capacity for coloration, in comparison with coniferous trees. A methodology was developed of cloning wooden particles, in the form of chips, with forced immersion in order to obtain established parameters of saturation and brightness. The experiments were conducted with chips of 15-50 mm long, 5-20 mm wide and 3-7 mm thick. The composition of colouring agent included water, acetic acid, and water-emulsion colourants of different types and colours (№1 – colour code (red, yellow, and brown) №2 – colorant (lilac and orange) and №3 – paint). Experience has shown the needed concentration of liquors and mass percentage of compounding ingredients. The research was undertaken to study concentration dependence on the time of allowance and saturation. In consequence of colouring experimental batches of chips, a painting saturation of 4-9 points was obtained at the allowance of 120 and 140 seconds. Dependence of brightness from solubility was determined, with high correlation between given parameters on Pearson Criteria (more than 0.9). Comparative analysis made it possible to discover that the better colouring of particles is created with the red paint. In this case maximum colouring effect is achieved with liquor of water-emulsion paint. Subsequent to the experimental results, a design of installation for colouring wooden particles was developed and patented

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

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

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.)
