Description
Nowadays some branches of the industry need hybrid or cascade systems of electric drives. Electric drives use up to 60 percent of all developed electric power therefore with improvement of massdimensional indicators and power characteristics of the considered devices necessary technical characteristics are reached and losses of electric energy decrease. When creating electric drives of various designs, it is important and rather difficult to calculate an electromagnetic system. Classical approach to design of data of systems has a number of shortcomings that demands creation of new approaches or adjustment and addition of the known methods and approaches. In the article, another approach to design of the developed systems of the electric drive is offered

FORECASTING OF REGIONAL GRAIN MARKET DEVELOPMENT
DescriptionForecasting the state of external and internal industry environment by assessing the impact of factors variety and analysis is the basis of the grain subcomplex purposeful development. It is necessary to take into account the integration of the industry into particular region environment, which requires additional consideration of natural factors in the forecast. Theoretical and methodological guidelines which define characteristics of the forecasting in the particular area, are designed to provide justification for that choice. Best results are obtained predicted values found by rapid and short-term models, as in a short period the trend rarely changes its direction and thus changes the value by several times. Forecasting methods can be divided into two major groups: intuitive and formal. As a dynamic system, the market (in particular the grain market) requires the usage of complex methods for forecasting time series of key market indicators. According to our opinion, the optimum method of forecasting the regional grain market conditions is based on the following principles: reliability, systematic analysis, taking into account factors that may have an impact in the long term; validity of the scientific justification i.e. obtaining a similar result when re-modeling of the experimental data; the adequacy of the results obtained after forecasting the experimental data; reliability and accuracy of the forecast assessment for its possible adjustments; cleariness of language, which should be understandable for the decision-makers; planned nature of the forecast

THE METHOD FOR CONTROLLING POTATO TUBERS HIDDEN DAMAGES
DescriptionWhile mechanical harvesting of potatoes, about 20-40% of the tubers get damages. Dynamic loads, injuries of the tubers, causing internal damage – which is browning of the flesh of the tuber, which occurs in the process of its storage. At the same time, ways to express control of damage to potato tubers will allow both reducing damage during harvest, and promptly sending damaged potatoes for recycling before the results of mechanical stress for the tubers during harvesting. The definition of internal damage to the potatoes is possible because of the analysis of the different elasticity of the tissues of damaged and undamaged tubers. The value of overpressure of the device is chosen such way that during deformation of tubers there mainly has been compression of the damaged tissues of the tuber, with the least turgor. The degree of damage of samples of tubers is determined by the ratio of the volume of damaged tissues of tubers to the total volume of the sample. We have given the mechanical properties of tissues of tubers, fruits and root vegetables, their structure, dimensional characteristics, it can be assumed that the use of this method of determining internal damage possible for apples, carrots, beets and harvest of other crops. Use of damage control will enable timely identification of hidden damage and make it possible to eliminate their causes, which lead to increase loss products

CHARACTERISTIC OF EXISTING TECHNOLOGIES AND WAYS OF STORING OF TOPINAMBUR TUBERS
DescriptionThe article analyzes the existing technologies and methods of storage of tubers of topinambur. We have analyzed the traditional methods of storage of tubers of topinambur - in containers, boxes or bags in storage or in the ground clamps. Russian and foreign topinambur tubers storage technologies in modified atmosphere, with use of easily removable wax coating, with plant extracts treatment, at different storage temperatures are studied. We have also carried out analysis of scientific and patent sources led to the conclusion that existing technologies and methods of storing topinambur tubers, which do not allow reducing to the maximum extent the weight loss and the inulin hydrolysis during storage. A reasonable conclusion was made about the advisability of further studies in the field of innovative technologies and methods of preparation for storage and storage of topinambur tubers, ensuring minimal weight loss, as well as maximum preservation in their structure of inulin, vitamin C and other biologically active substances during storage

REDUCING ENERGY CONSUMPTION IN AGRICULTURAL PRODUCTION (POTATO EXAMPLE)
DescriptionIn 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

LOGARITHMIC LAW FOR DYNAMICAL SYSTEMS FROM QUARKS TO GALAXIES
01.00.00 Physical-mathematical sciences
DescriptionThe article discusses various examples of dynamical systems in which the motion is determined by the logarithmic law - quark systems, hydrodynamic systems, galaxies. Set the general nature of angular motion on a hypersphere in a space of arbitrary dimension and radial movement 6D in the metric of a logarithmic potential. We investigate the 6D metric describing the case of motion with two centers of symmetry. It is shown that in such a metric exists a class of exact solutions, logarithmically dependent on the gravity center coordinates. It was established that in spiral galaxies the orbital motion is due to the logarithmic potential, which is the exact solution of the field equations of Einstein's theory of gravity. The most well-known and widespread in nature case is turbulent flow over a smooth or rough surface, in which the mean velocity depends logarithmically on the distance from the wall. We derivate the logarithmic velocity profile in turbulent flow from the NavierStokes equations. An analogy of the logarithmic velocity profile and the logarithmic law in the case of erosion of materials under impacts been proposed. In electrodynamics, Ampere's law, which describes the interaction of current-carrying conductors, is a consequence of the logarithmic dependence of the vector potential of the distance from the conductor axis. There is, however, an alternative derivation of Ampere law of the Riemann hypothesis about the currents due to the motion of charges

THE NORTH CAUCASUS IN 1918-1919 YY: POLITICAL REGIMES AND FORMS OF THEIR STATE ORGANIZATION
DescriptionThe article is devoted to process of the state development and emergence of new forms of the government in the region of the North Caucasus during the Civil War. The author tells how forms of a political system and the government in the region after October revolution of 1917 have changed. He analyzes the process of emergence of the new military-political modes and character of a state system in its various areas. In the article, the political background of appearance of new forms of statehood and power organization is also considered. The author equally investigates the forms of the state life created by Bolsheviks and their supporters, and the forms of their political opponents – representatives of the white, antiBolshevist movement. The author emphasizes that it was the period of disintegration of traditional Russian statehood and traditional forms of the organization of the political power in the region. New options of the state system which are directly connected with the crisis of the Russian society in 1917 y. came in the region to replace the old ones. In some cases, they represented rather non-standard forms of the organization of the government, including formation of the Soviet republics in the territory of the region, appearance of the ataman power and military dictatorships. On the one hand, they were based on ethnocultural specifics of regional life, and on the other hand they were defined by the crisis of the period of the Civil War

PARTICLE DYNAMICS IN METRICS WITH LOGARITHMIC POTENTIAL
01.00.00 Physical-mathematical sciences
DescriptionParticle dynamics in metrics with logarithmic potential The work considers the problem of modeling the motion of particles in a unified field theory to 6D, in theory, supergravity in the 112D and metric galaxies. We have investigated a centrally symmetric metric in the 112-dimensional Riemannian space, which depends on the radial coordinate, time, and 110 angles. We present a system of equations describing the angular movement on a hypersphere of any dimension N. It is shown that the motion on the hypersphere depends on the 2 (N-1) of singular points. We have installed general nature of relativistic motion on a hypersphere when it is displayed on the plane and in three-dimensional space. It is shown that the motion determined by the reflection from the singular points that of motion on the plane in some cases leads to thickening of the trajectories in the neighborhood of sides of the rectangle. The 6D investigated metric describing the case of motion with two centers of symmetry. It is shown that in such a metric exists a class of exact solutions, logarithmically dependent on the gravity centers of origin. It is found that in this system there is a motion with condensation paths around the sides of the rectangle, due to scattering of test particles gravity sources. We set the general nature of angular motion on a hypersphere and radial movements in 6D in the metric of a logarithmic potential. It is proved that similar solutions with logarithmic potential exist in galaxies metric in the metric of Einstein's theory of gravity. The article also describes the connection of the solutions to the nonlinear electrodynamics, and with a theory of quark interactions and Yang-Mills theory
