ECONOMIC ASPECTS OF INCREASING EFFECTIVENESS DEVELOPMENT IN GRAIN BUSINESS
DescriptionThe article highlights high level of agricultural production and promising export potential of the Krasnodar region. The authors provide analysis of market segments of export growth in grain business, consider opportunities of increasing competitiveness by improving production of grain, import substitution, and focusing on export. It is noted, that the cost of imported food in value chain terms in our country had reached an enormous rate, and that government had realized the need of strengthening food security and transferring production of traditional produce, which are forming the basis of consumption of the local population, to the domestic market. The authors point out that we need temporary moderate state protectionism and protection of the domestic market with the aim of modernizing the economy, attracting investors in the important fields of production with high risks. The main problems and solutions that will help to further successful implementation of this strategy in the sectors of grain economy are also defined. The article shows that the Krasnodar region has the most effective rural industrial structure, the best climate in the country, enlarged crop rotation, cheap labor resources, extensive experience in agricultural business. The authors propose adopting a set of measures of reducing systemic risks and enhancing competition in grain business; to reduce lending rates to 3-5 % to revive the lost ground in livestock breeding, particularly in pig and cattle, the basis of which is the production of grain, and also improve the scheme of distribution of state support

THE METHOD OF CALCULATION OF FILTERS FOR STATIC CONVERTERS OF ELECTRIC POWER
DescriptionOne of the important issues in the design of static converters of electric power, i.e. rectifiers and inverters, is to calculate the parameters of the output and the input filters. Output filters are designed to improve the quality of output voltage of inverters, and input filters are created to reduce ripple of the input voltage of the converter that occur when commuting power semiconductor devices, and smoothing fluctuations of the current consumed from the power supply. The complexity of analytical description of the harmonic composition of the output and the input of the voltage rectifiers and inverters makes it difficult to develop some accurate methods for calculating the parameters of their filters. At the same time, considering the discreteness of the number of possible parameters of real elements of the filter, the practical value of such techniques with a high analysis accuracy of the harmonic components is negligible. In this article, we suggest the technique of the simplified calculation of output and input filters for passive LC filters rectifiers and inverters. At the same time, the practice of mathematical modeling and design of transducers has shown that the calculations of the filter parameters for rectifiers and inverters are not significantly different from each other. Therefore, the analytical expressions for calculation of the filter parameters of rectifier used ripple coefficient, and if necessary the calculation of the filters of the inverter, instead of the pulse number in the formula can be substituted with the value of the harmonic; in addition, we have also taken into account the value of the load power factor

ESTABLISHMENT OF THE RUSSIAN OILBANK PREMIER AS ONE OF WAYS TO INCREASE ENERGY SECURITY IN RUSSIA
DescriptionThe article deals with the energy security of Russia in conditions of sanctions and the globalization of the modern economy in the world community. It is substantiated that energy security is the main factor of political and socio-economic stability of each state. Russia is not an exception. For many years it has been the world's largest net exporter of oil and gas, mainly due to the weakness of the economic system; the main problems of the oil refining industry are considered; we have also given the definition of energy security; the energy security of Russia is analyzed in the conditions of the crisis. An estimation of the export of domestic goods is given, the reserves of the regions are considered according to the level of extraction of oil resources, the rating of the largest oil companies is determined by the level of average daily oil production. It is concluded that for a successful export, the redistribution of significant oil reserves between regions within the country will require a relatively long period, not one or two years. It was revealed that the level of domestic production is not fully capable of providing consumers with the necessary products, for which Russia implements the policy of modernization and reconstruction of the fuel and energy complex. Russia has been one of the leading oil exporters for many years, the main indicators of the oil sector have been examined, the definition of economic security and energy security has been defined. The energy security of Russia is analyzed in the conditions of the crisis, as well as the globalization of the world economy. A brief description of the energy security policy of the Russian Federation is given. An assessment is given of both the world oil sector and the Russian oil sector, based on this assessment, a conclusion has been drawn about the deteriorating conjecture of the oil industry. A correlation-regression analysis of the effect of oil prices on the quotes of the Russian ruble was conducted, and on the basis of the findings it was concluded that the Russian economy is in a sufficiently strong dependence on oil prices. The possible variant of reducing such dependence through the increase in the role of SPIMEX in the international arena and the creation of an oil benchmark in the Russian Federation were considered and described

Description
The transportation process plays an important role in the delivery of agricultural products to the consumer. On how well the fruits are preserved, their grade will depend, and, consequently, the price of them. It is known, that the annual damage from losses of agricultural products in the agro-industrial complex amounts to 8 billion rubles, according to various estimates. A large number of different factors affect the safety of fruits during transportation: temperature, humidity, smoothness of the vehicle, type of container, etc. The more factors will have a negative impact on fruit and vegetable products, the more losses will ultimately be. The appearance of dents and abrasions on the fruits gives rise to the formation of foci of rot, leading to damage to the transported products, and, as a consequence, reducing the grade. In order to reduce the losses of fruit and vegetable products in the process of transportation, the USSR and the Russian Federation have been and are working on the creation of containers and ways of transporting pomegranates. All of them, according to the authors, are able to reduce the dynamic loads that arise during the transportation process and have a negative impact on the transported products. However, due to various circumstances in commercial gardening all these developments have not been extended

RESTORATION OF WORN DETAILS OF AGRICULTURAL MACHINERY WITH GALVANIC COATINGS
DescriptionWe have conducted experimental and analytical studies showing the relationship of constant and pulse forms of current sedimentation on the physicochemical properties of chrome coatings: adhesion strength to the substrate, residual stress, fatigue life, elongation and contraction, yield stress, and endurance. We have shown the methods and modes of use of dilute electrolyte of chromium plating with organic additives, is capable of applying a chrome coating on parts of agricultural machines, surpassing the properties of the coatings obtained from electrolytes that are recommended by the GOST standards. The proposed hardening chemical-thermal coating technology for chromium in the manufacture and repairing of worn parts of agricultural machinery (rods of hydraulic cylinders, journals of crankshafts, spools, parts, gearboxes and transmissions, etc.), identifies the consumption of additives modifiers, proposed methods for their determination, confirmed by patents for inventions. The proposed technology of worn-out surfaces of parts of agricultural machinery of layer-block structure of the chromium coatings with improved properties. The influence of modifying organic additives on the structure of the intermediate surface film of colloidal trivalent chromium compounds, which in combination with the parameters of the bipolar pulse current allows you to specifically adjust the physical and mechanical properties of crystals of the deposited chromium layer with a grid of cracks, and without them for the required operating conditions of dry friction or oil environments, which increases the durability of the parts during use. The increase in yield, at the current 6-8 %, to 4 times reduces the degree of hydrogenation of the restored details, up to 3 times reduces internal friction, roughness, improves the limits of strength, toughness, elongation and contraction, increases corrosion resistance up to 3 times, obtained chromium coatings

DESTRUCTION OF SOIL STRUCTURE WHEN CULTIVATING GRAPES
06.00.00 Agricultural sciences
DescriptionThe ecological state of soil on the globe is unstable. Intensification of agricultural production is accompanied by negative trends in changes in soil fertility. One of the most important indicators of soil fertility is its structural state. With a long time cultivation of grapes in one place, the physical properties of the soil deteriorate. The purpose of our research is to study the process of destruction of soil structure during the cultivation of vineyards. The object of research is the soils of plots of various agricultural uses (vineyards, field crop rotation, forest belts). The research methods used in the work are route-field surveys, a laboratory study of the waterphysical properties of the soil. The article presents the data of the structural-aggregate composition of the soil from plots of various agricultural uses. From the data given, it can be seen that the soil occupied by the vine plantations is characterized by a poor structure and low structure of the arable horizon. The share of agronomically valuable aggregates is 40.4%, the structural coefficient is 0.68 units, while in the forest belt this figure is 5.7 units. The increased mechanical load on the soil during the cultivation of vineyards leads to a deterioration in the physical properties of the soil. Soil with low indicators of physical condition is more susceptible to erosion processes, such as water and wind erosion. Water erosion annually causes great damage to agricultural lands throughout the world. The article clearly demonstrates and scientifically substantiated the negative effect of the system of soil content of vineyards on the type of black steam. Also proposed are ways to reduce the mechanical load on the soil and prevent the development of degradation processes in the soils of vineyards

SUPPLYING THE GREENHOUSES WITH POWER BY THE USE OF ASYNCHRONOUS GENERATORS
DescriptionDue to the recommendation of the World Health Organization, the standard rate of vegetables consumption for a person per year is 130-150 kg, including up to 15 kg of fresh production during the off-season. To meet these standards in Russia, the construction of greenhouses and greenhouse complexes was sped up. To cultivate the bulk of vegetables in the conditions of protected soil we have mostly used winter greenhouses. At the same time, in terms of the climatic conditions, the main production costs are accounted for energy carriers (up to 60 – 70%). The main consumers of energy in greenhouses are plants’ lighting and creation of the required temperature conditions for plants and soil. Annual increase of rates for energy carriers affects the cost of the greenhouses’ production. To increase the energy efficiency and independence in greenhouse complexes, it is proposed to use installations based on gas reciprocating units (GRU) for the production of two types of energy – electric and thermal. Such installations can run on the natural gas and other types of fuel. The drawback of existing installations is that they are mainly produced abroad or consist of the foreign components. As an alternative, we offer new technical solutions, which were developed and patented in the Russian Federation. What makes these solutions original is that asynchronous generators in the installations are used with various control schemes
