PROBABILISTIC-STATISTICAL MODELING THE INTERFERENCES FROM ELECTRIC LOCOMOTIVES
01.00.00 Physical-mathematical sciences
DescriptionThe movements of electric locomotives create the interferences affecting the wired link. The creation of sufficiently technical effective and at the same time cost-effective means of protection from wireline interferences generated traction networks assumes as a preparatory phase to develop mathematical models of interference caused by electric locomotives. We have developed a probabilistic-statistical model of interferences caused by electric locomotives. The asymptotic distribution of the total interference is the distribution of the length of the two-dimensional random vector whose coordinates - independent normally distributed random variables with mean 0 and variance 1. Limit theorem is proved for the expectation of the total amplitude of the interferences. Monte-Carlo method is used to study the rate of convergence of the expectation of the total amplitude of the interferences to the limiting value. We used an algorithm of mixing developed by MacLaren-Marsaglia (M-algorithm). Five sets of amplitudes are analyzed, selected in accordance with the recommendations of experts in the field of traction AC networks. The most rapid convergence to the limit takes place in the case of equal amplitudes. It was found that the maximum possible average value of the amplitude of the random noise by 7.4% less than the previously used value, which promises a significant economic impact

RELATIONSHIP OF SCIENCE, PRODUCTION AND EDUCATION IN THE EXPERIENCE OF REFLECTION
DescriptionThe article raises the issue related with some functioning features of modern science. Special attention is paid to the process of interaction between science, production and education. The science role in reproduction and development of modern productive forces is in creating the productive forces in the form of knowledge and transfer them from this form into real factors of material production. This process is carried out by implementing in the material production technical, technological and nontechnical innovations through the system (or canal) of implementation by the reproduction of qualitative features of the human resources in the system of general, special and higher professional education. It is should be noted that in modern globalization conditions both production means, human resources and social productive forces are reproduced neither spontaneously nor even with use of the common mind, but on the ground of transference of the productive forces created, first of all, in the form of scientific knowledge to the material productive forces. The structures providing such transference and simultaneously mediating the connection of science with material production are the implementing system and educational system

DescriptionThe article reveals issues concerning the experiments on application of complex water-soluble fertilizer and straw mulching of row-spacing in sweet corn hybrid named Krasnodarskiy 280 CV growing management and the yield of milky ripeness. We have discovered that straw mulching in combination with complex water-soluble fertilizer named Vermisol used in 5-6 leaves, reduced evaporation and tended to moisture accumulation in soil what increased yield of ears for 0,6-1,7 t/ha. The lowest water-absorbing capacity in root-inhabited layer of soil (0-0,6 m) were 28,5 % from dry weight of soil in years of experiment. Registration of sum of precipitations in critical for corn period (in third decade of June and first decade of July) was in tolerable level. The best conditions of precipitation were in 2013, when in June and July the sum was 143 mm, and humidity of the air was in optimum level – 70 %. The temperature of the soil in 0-0,1 m layer in the day of mulching was the same as in the layer 0-0,05 m, tin increase for 5 0C in variants without mulching. The lower amplitude of temperature of the soil in vegetation period since the phase of 10-11 leaves had good influence for yield of milk maturity ears

IMPACT OF AN AMENDMENT FOR SOIL STRUCTURE IMPROVING ON SOIL AT SPRINKLING
06.00.00 Agricultural sciences
DescriptionThe article presents the research results of the impact of amendment improving soil structure on soil upon sprinkler irrigation of agricultural lands. It is proposed to use artificial aggregation of soil for water erosion control via composition of structure-forming materials. The developed composition includes slagheap rock, bentonitic clay, claydite screenings, and shell limestone. Adjusted analytical relations of the impact of the amendment on runoff coefficient depending on the intensity of artificial rain upon irrigation of agricultural lands, slope, and water permeability have been revealed. Regression analysis of spectral surfaces has shown that slope of irrigation site has a significant impact on the increasing of runoff coefficient values, while correlation coefficient equals to 0.97. Water permeability has negative correlation, -0.85, with increasing the values of runoff coefficient. The relation between runoff coefficient and intensity of artificial rain is less strong, 0.89. We have determined that applying of the given amendment provides decreasing of runoff coefficient by 15 % depending on the slope of irrigation site, and by 20 % depending on rain intensity. Experts in the field of land reclamation can use obtained analytical relations for predicting surface soil loss when estimating the efficiency of amendment applying to control soil erosion activities at agricultural lands

THE IMPACT OF THE SANCTIONS ON THE INVESTMENT CLIMATE AND INDUSTRIAL POLICY OF RUSSIA
DescriptionIn this article considers the condition of investment climate in the industry and the prospects of its change from the result of imposing sanctions from the West. This article considers common economic indicators of the Russian domestic market and defines priorities of increasing investment attractiveness in industry, simultaneously brings out positive and negative sides. We have determined that dependence of Russian regions from economic sanctions is very ambiguous. We have predicted the possible situations where the industry can suffer certain decline and also represented the fields of Russian industrial production where the indicators may have positive results from sanctions. The article indicates a number of spheres of domestic production which directly depended from external impact of foreign countries. It emphasizes the fact that in the order to rise the capital and economic growth we should create the favorable qualitative investment climate and develop own production capacities on the basis of innovation and modernization. In this article we are taking into account the fact of growth of investment activity from the position of financing. Effective instruments for attracting investment are: the creation of special economic areas of advanced development, implementation of measures of reducing administrative barriers of business. Attractive investments will create the financial basis not only for import substitution, but for reindustrialization of the industry

STATE SUPPORT AS AN ELEMENT OF THE LAND RESOURCES REPRODUCTION
DescriptionThe implementation of organizational and economic activities, the most important of which is the mechanism of state support, is ensured by high efficiency of land use while maintaining soil fertility. In order to adapt to the requirements of the WTO, the order of distribution and the provision of subsidies to decoupled support to farmers in crop production (per hectare subsidies) was introduced in Russia since the beginning of 2013. These payments are directed to the compensation of the costs for the purchase of fertilizers and plant protection chemicals, financing measures to improve soil fertility and soil quality. The order of per hectare subsidies to farmers in specific subject of the Russian Federation is fixed on regional legislative level. In addition, each region has the right to establish its own criteria for budget allocation. The main conditions of the subsidy per hectare in the Krasnodar region are sown area under crops, the area sown to perennial grasses, and the area on which organic fertilizers have ever been put.This approach will contribute to the unjustified expansion of acreage by land users in the conditions of extensive production in violation of the science-based zonal technologies of field crops cultivation and, consequently, a violation of the process of soil fertility reproduction. In order to overcome the problem, the regional criteria for granting per hectare subsidies are specified in the article. They include not only traditional terms but also the level of land use efficiency and its quality, which will promote economic entities in the area for more efficient implementation methods of soil fertility reproduction

Description
The article discusses approaches to differentiation of agricultural enterprises of the Krasnodar region on the production potential. As the object of study we have selected 640 agricultural enterprises of the Krasnodar region for 2013. Cluster analysis allows visually differentiate organizations in economic parameters. The advantage of this approach is evident when analyzed a large number of organizations and performance. It is preferred that clustering is made using hierarchical cluster analysis and k-means. The results of clustering agribusiness enterprises of the Krasnodar region on the main economic indicators were given. During the analysis, we revealed that the AIC enterprises of the Krasnodar region generally form five clusters. Cluster 1 is characterized by a very high level of development of the productive capacity of agribusiness enterprises, consists of 12 organizations and is defined as "extra large" organization. 2nd cluster is characterized as "large", it includes 25 agricultural enterprises. 3rd and 4th clusters - as "average", they account for 60% of the acreage, 52.6% of fixed assets for agricultural purposes. 5th cluster is represented as "small", is a leader in the number of organizations - 371 units and contains a minimum number of employees - 30 people. It is assumed that these approaches can be used for analysis of agricultural organizations of the Krasnodar region with different levels of specialization and in other studies

PRINCIPLES AND PRACTICES OF SEED SELECTION NOWADAYS
06.00.00 Agricultural sciences
DescriptionThe article presents the author’s insight into the theoretical foundations of plant breeding for self-pollinators and cross-pollinators. From the author’s point of view, plant breeding techniques depend on a type of pollination, population propagation and isolation from other variety pollen. Adaptive properties of crops are described as ones depending on a genetic type (genetically pure lines, populations, hybrids, pure varieties and clones). The key role of seeds in preserving a plant variety, or a cultivar, is emphasized. In the article, cultivar and yield qualities of seeds are characterized. The reasons for seed deterioration and yield decrease have been looked into. Improvement of main crops such as wheat, barley, rye, rice, soybeans, maize, triticale, sunflowers, potatoes, sugar beets is characterized in detail. The author shares the traditional point of view on the seed breeding program. It includes following steps: development phase (breeder’s seed), maintenance phase (in which a quantity of seed is maintained under high standards) and the distribution phase (production of commercial seed for distribution to the public). The difference between primary and secondary seed selection is explained. The best periods for crop rotation and crop renovation are also described. The legally enforceable standards of quality and genetic purity for different crops are presented in the article. It is pointed out that it is vital to maintain high cultivar qualities after multiplication and distribution of the new variety. Only large-scale pedigree system for seed production promotes it
