IMPROVING THE PHOTOELECTRON SEPARATOR WHEN SEPARATING SUNFLOWER SEEDS
DescriptionTraditional processing technology of piles of sunflower seeds in agriculture requires consecutive through the whole set seed-cleaning machines installed in seed-cleaning complex or aggregate, for each stage of which are organic impurity, broken seeds, shriveled and milled seeds. The seeds of the main culture are subjected to long-time effects of the working bodies, leading to their injury and the necessity of manning the production line machines the same performance that is not rational. One of the ways to enhance the process of separating the seed material in seed-cleaning complex is its fractionation by applying photoelectron separator at the final stage of seed treatment. Qualitative performance of photoelectron separator on fractional technology showed that the purity of the seeds varied from 99.80 up to 99.98% depending on their size Ø7–Ø8 mm Ø8–Ø9 mm, respectively. The content of seeds of the main culture in the waste ranged from 65.60 % (fraction Ø7–Ø8 mm) to 68.83 % (fraction Ø8–Ø9мм). The weight of 1000 seeds ranged from 117 g (fraction Ø7–Ø8 mm) to 146 g (fraction Ø8–Ø9мм). Seeds obtained in fractions and existing technology (without fractionation) meet the requirements of GOST. The output of treated seeds in the fractionation varied from 93.20 % (fraction Ø7–Ø8 mm) to 92,90 % (fraction Ø8–Ø9 mm). Comparative tests of photoelectron separator F 5.1 in seed-cleaning complex by the division of sunflower seeds on the existing and fraction technology showed that in the photoelectron separator it is necessary to use fractional technology. So, as it allows reducing the content in waste of seeds of the main culture and increase the qualities of seeds depending on their size fractions

AN ELECTRIC MODEL OF A CITY TRANSPORT NETWORK
DescriptionThe main characteristics of a transport network are the intensity of the traffic flow, speed and density of its traffic. Comfortable driver's traffic density is determined by the rule of the traffic police, which is "clearance between cars on the road should be a tenth of the speed of movement." We have built a reference curve of the density function of the flow of vehicles on its speed, which is basic when simulating a traffic flow. The article describes a model of electrical city transport networks, allowing calculating traffic flows, their speed, the density and the number of traffic lanes by means of laws of electrical engineering. We have also compared electrical concepts (current, resistance, electro-motive force, etc.) and transportation (of intensity-flow lane road, transport driving force, etc.). For the transport network there are methods of calculation of electrical circuits - a method of Kirchhoff's laws, loop currents, etc. We have confirmed the correctness of electric models and the possibility of its use for the calculation of transport networks; as well as we have presented an example of the calculation

ACCOUNTING ASPECTS OF THE UNIFIED AGRICULTURAL TAX RISKS REDUCTION
DescriptionBusiness risk is a result of the business operations like taxes. Concerning of the issues related to the development of a strategy functioning economic entity are becoming popular. This strategy considering the law brings to optimizing the value of the tax payments of the organization and reduces the risk of tax risks. In this situation, a special role should be given to the orientation of the accounting system for the risk of economic activity in the development of accounting and organizational aspects that ensure the formation of the tax base for various taxes, and use the special taxation regime. The system of risk-based accounting consists of risk-based accounting policy for taxation regime, verification of the rights of using UAT, foundation of deferred taxes, revision of tax risks which are based on public criteria of tax offenses, the method of distribution incomes and expenses between different taxation regimes, monitoring an agricultural production, the inspection of tax errors

Description
The article considers prerequisites for the development of complex software and tools for data analysis, modeling, forecasting and management decision making in the management of IT-projects. System of decision support can facilitate the work of heads of enterprises and increase its efficiency. They significantly accelerate the solution of problems in business. In the organization, there is a software complex, which suggests that the transmission of information about incoming orders and deadlines for every Department and information on the implementation of the orders of the head is performed via the software package. Using software system, the client leaves a request for the execution of services. The Manager sends a request to the appropriate Department. Units, in turn, convey information about the status of the application via the software package. The software package provides fast remote bilateral communication in electronic form between the client and Manager and between Manager and the departments. In a company, the head and head of sector perform the coordination of work in implementation of IT projects. However, there are a number of human factors that make people cannot keep track of the timely execution of all requests from subordinates

DescriptionOn the example of middle-aged and mature valuable forest stands we have brought an assessment of forestry and economic efficiency of various options of silvicultural actions for the reconstruction of invaluable young growths (17 objects with a total area of 102,6 hectares) which was carried out in 1947-1959 and to formation of plantings from subgrowth and young growth of the coniferous breeds kept when carrying out gradual and continuous cabins in 1962-1996 and also from forest cultures (8 objects of 44,9 hectares) for conditions of the coniferous and broad-leaved woods of the Republic of Tatarstan. The results of the researches showed that the best indicators of forestry and economic efficiency of actions of care of the woods by reconstruction are observed in pine plantings at a continuous way: the grown-up wood reserves on a root (346-522 m3/hectare in 55 years) exceed stocks of modal forest stands on 109-288 m3/hectare with economic efficiency within 10625-50659 rub/hectare. Slightly less efficient - larch and spruce plantings at a corridor way of reconstruction. Similar indicators of actions for formation of plantings from subgrowth represent positive results as well: forestry efficiency made from 31 to 208 m3/hectare, economic - within 10584-26846 rub/hectare. Based on the researches we made conclusions, offers and recommendations for practical use in forestry of the Republic of Tatarstan

MODERN PROBLEMS OF ANIMAL HUSBANDRY OF THE KRASNODAR REGION: STATE AND SOLUTIONS
DescriptionThe Krasnodar region is a major producer and supplier of agricultural products. Livestock development in the Krasnodar region has been supported by the following factors: favorable climate, the intensive development of crop production, the need of the population in livestock production and others. Recently, however, there is a decline in livestock production, which is due to the influence of negative factors. Industry analysis showed the problems that hinder the development: high costs for the purchase of feed for livestock and poultry, low purchase price of products, pedigree cattle deficit, lack of foreign investment, low level of modernization of production. The development of the livestock industry of Krasnodar region must be associated with the use of optimal feed rations of cows, implementation of new methods of genetics and selection, implementation of strict accounting and control of livestock, improvement of livestock veterinary support. This will increase the milk production and improve the efficiency of the industry. The article provides the optimal parameters of the diet of cows, calculated by the authors and based on the use of methods of optimization and simulation. It is based on economic and mathematical model developed by the staff of the Department of Economic Cybernetics of Kuban State Agrarian University

PRINCIPLES OF ORGANIZATION AND OPERATION OF COLLECTIVE TAXI
DescriptionThe volume of transportation of passengers by taxi is 6-9% of the total traffic of all kinds of public transport depends on the size of the settlement. The main purpose and the advantage of a cab is providing services for the transportation of passengers on the route, appointed by the customer, around the clock work and comfortable travel. To unload the transport system of the city, especially during peak hours, it is proposed to introduce a new type of operational-servicing passengers - a collective taxi. It is designed to transport multiple passengers traveling in the same direction, but with different destinations landing, while the fare is much lower than in a normal taxi. In organizational sense, collective taxis can be a unitary taxi company with the official standard structure and the quantity of the workers or a division of the taxi park of the city
