REDUCING ENERGY CONSUMPTION IN AGRICULTURAL PRODUCTION (POTATO EXAMPLE)
Description
In recent years, in many countries around the world, much attention is paid to the issues of ensuring of rational use of energy resources, due to a number of objective factors, chief among which are: the lack of own energy resources to meet domestic energy needs; the sharp increase in the cost of production and the production of energy resources; further growth in energy needs; the presence of large potential opportunities to reduce unproductive losses of fuel and energy. In the world, the challenge now is to ensure a gradual but steady transfer of the economy on energy saving way of development. To achieve the goal of reducing energy costs we might use two ways: firstly, the widespread introduction of energy saving technologies, and secondly, the reduction of material production, improving its quality and service. In agriculture, the improvement of the technological process can be carried out using new tillage methods, improving the organization of production and tools. Further development of mechanization in agriculture will contribute to further growth of electrification in the agricultural sector, which will significantly reduce the use of the most expensive and limited energy resources. The article offers a technique of the estimation of the efficiency of consumption of energy in agricultural production. In order to compare the efficiency of machines in the cultivation and harvesting of potatoes, there was conducted an energy assessment of the operations of modern technology. As variables, there were investigated different operation modes of the machine: working speed and working width, depth of stroke of the working bodies. In the process of evaluating energy operations, modern technology to prepare the soil for planting potatoes was determined humidity, mechanical composition and soil type. As a main factor in the analysis of technological methods, we have taken the overall specific energy consumption and specific energy consumption for the digging below tuber formation. Analysis of theoretical researches of agricultural machinery has led to the conclusion that the energy cost of implementing the technological process in the machines of different designs varies

HARDENING AND SOFTENING OF CLAY SOIL
Description
Hardening of clay soil manifests in the form of increase of the resistance of sample to shear deformation. The shear tests of normally compacted and overcompacted soils give values of peak strength at small strains and long-term strength at high. A shear test with constant strain rate of deformation (CRD) with continuous recording of resistance encounters uneven resistance change and the cyclical rate of change of resistance (RCR). The identification of cycles of the SIS allowed us to divide the deformation in each cycle for elastic and inelastic, corresponding to the ascending and descending branches of cycle. On an interval of the total resistance, the increases of the increment of inelastic strain are positive up to some critical value of the total deformation of the sample at which their sum reaches a maximum. This maximum is adopted as a measure of hardening. With further shearing of the sample, inelastic increments are negative, and their sum is monotonously decreases and reaches negative values for the total destruction of the sample. This value is taken as the softening. A symptom of total failure of the sample is the decline of absolute values of inelastic increments of resistance to zero. In general, the trend of the increments of inelastic and elastic increments of the resistance of the sample indicates the development of the destruction of the soil sample on the sliding surfaces and, in particular, yielding of the total surface. The sum of elastic increments of the resistance monotonically increases throughout the shear

Description
The reaction of winter wheat of Krasnodar Agricultural Research Institute selection that is included in the State Register of selection achievements in the Russian Federation, on the predecessor, the sowing time and the level of mineral nutrition in 2008 - 2010 was studied in "Severokubanskaya agricultural experimental station" P.P. Lukyanenko Krasnodar Agricultural Research Institute, located in the northern area of the region. The objects of research were cultivars ‘Bezostaya 1’, taken as a standard, ‘Tanya’, ‘Grom’, ‘Sila’, ‘Ligue 1’, ‘Irishka’ and ‘Yumpa’, with a specific weight of strong wheat (excluding the cultivar ‘Bezostaya 1’) - 57.1%, essential - 28.6%, weak - 14 3%. The predecessors are winter wheat, sunflower, white mustard. Seed dates: the 20th of September (optimal for determining the originator of the cultivar) the 1st and 10th of October. The background of mineral nutrition is N0P0K0, N60P30K30 and N120-160P90K60. The soil is an ordinary powerful heavy-loam chernozem with humus content in the soil layer 0 - 30 cm 3.95 - 4.00%, of mineral nitrogen - 8.3 - 10.7 mg / kg of soil, of mobile phosphates - 22.4 - 26 6 mg / kg of soil, of exchangeable potassium - 330 - 360 mg / kg of soil. Weather conditions during the research were extremely contrasting, both by the precipitation and by the temperature conditions. Based on these studies, it was found that five or six cultivars of this crop that differ in biological and economic features, the reaction on the predecessor, soil fertility and sowing terms as well as adapted to the specific soil and climatic conditions should be used to obtain consistently high yields of winter wheat. Well-chosen cultivars, predecessors and sowing terms predecessors allow without additional cost on the unfertilized background to increase the yield on 0.20 - 0.79 t / ha. Together with the growth of yield, the technological quality of grain is improved: protein content by 0.5 - 2.4%, fibrin content - 1.7 - 7.6%. The principle of mosaic use of cultivars with specific predominance of strong wheat is 57.1%, essential - 28.6%, weak - 14.3%, it allows to produce the grain when you apply the minimum dose of 12.5% protein content, 20.9% of fibrin content. When using N90P60K60 respectively 13.3 and 23.6% at a dose N120-150P90K60 - 14.4 and 26.8% with an average of 13.5 - 24.0%

THE CHARACTERISTICS AND THE TRENDS OF DEVELOPMENT OF THE REGIONAL HOUSING MARKET
Description
It is proposed to differentiate the housing by the various qualifying characteristics, including ways of conducting transactions on the primary and secondary markets, organized and unorganized; in and out of the exchange markets. The signs of the functional purpose of the housing market are systematized, the composition of market participants are detailed. The author provides the statistical information on the key participants in the regional housing market, and the main investors in this market, indicating areas of interest. As investors, in the local housing market are considered: the organs of management of state property, municipal property, civil persons, legal entity, organizations, physical and legal foreign persons, and other participants in housing projects. It is noted that in practice, the greatest distribution was achieved by the following forms of participation in the construction: equity, the issuance of securities to attract investors, banking and mortgage lending. Than, this practices are analyzed, and the advantages of each of these systems are systematized. There is also a system of performance indicators of the regional housing market, consisting of three groups: volumes of housing construction, the cost and availability of housing. For the third group, it is proposed to add the housing affordability index for which the method of its calculation is shown. The simplicity of the recommended approach allows to carry out operative calculations in the practice of construction with determination of affordability of housing for certain categories of population based on its income, at all regional housing markets. The economic essence of this indicator characterizes the ratio of the market price of housing and the income level of the population. The retrospective and prospective trends of development of regional housing policy are shown

10.00.00 Philological sciences
Description
The article analyzes the literary prose by Olga Slavnikova in the context of the literature of the late XX – early XXI centuries. The work of the writer is poorly investigated; the study of it is presented in modern literature only in the form of reviews and analysis of some of the concepts and motives. Scientific paper actualizes the problem of artistic method in the works of the writer. It is difficult to classify into one particular artistic method the work of many modern writers. The installations of several trends intersect in works some of them, even contradictory sometimes. Creativity by Olga Slavnikova isn’t exception in this series. At all levels of her prose, we have revealed various aspects that characterize the work of Slavnikova from the point of view of postmodernism, magical realism and women's prose. Categories of Death and Emptiness, the idea is the signified of existence and the illusory nature of the real are purely postmodernist, from the point of view of magical realism examines the images of metaphysical beings and the other world, also mentions personal and psychological motives as an art installation of women’s prose. Furthermore, with a postmodern understanding of reality realistic psychology characterized for all works, some constants of postmodernism are revealed using style settings of magical realism

ECONOMIC SECURITY OF RUSSIA UNDER THE IMPORT SUBSTITUTION POLICY
Description
Instability of economic processes and exacerbation of political tensions regarding Russia require measures in foreign trade policy, which are able to increase the economic security of Russia. The import substitution policy is considered one of the main directions nowadays. There have been considered two directions of the state policy for displacement or substitution of imported goods in the domestic market. There has been also reported the structure of the country's merchandise imports during the period from 2013 until 2015, resulting in a detected negative dynamics of imports, which indicates a successful beginning of the importsubstitution policy. Gradation of the main economic activities according to dependence on imports has allowed identifying the most import-dependent activities and the most available ways to form the import substitution. Threshold amount of economic security of the country has been considered to characterize the external economic security of Russia and some other countries of the world. There has been identified the necessity of state aid, which is reflected in the program of support for transport engineering industry for 2016, subsidies from the federal budget to participants of industrial clusters, the elimination of discriminatory relationships between credit financial institutions and industrial enterprises, the provision of state guarantees for loans to strategic enterprises and organizations of the country
