DescriptionThe article presents results of the study of yield, mechanical composition and quality of bunches of newest white grapevine varieties called Artemis, Sauvignon tamanskii and Inkroche tamanskii, in the conditions of Taman in the Krasnodar region. The yield of the studied genotypes ranged from 10.4 to 13.3 t / ha: the highest yield was in Artemis, and the lowest – in Sauvignon tamanskii. The average weight of the bunch was in Sauvignon tamanskii (152 g), the variety Artemis had 143 g and Inkroche tamanskii had 130 g of bunch weight. The percentage of berries in clusters ranged from 95.3 in Artemis to 95.9 in Inkroche tamanskii and Sauvignon tamanskii. The ratio of fruit mass to the mass of crests was 20.3 in the varieties of Artemis and 23.5 in Inkroche tamanskii and Sauvignon tamanskii. In genotypes of Artemis, Sauvignon and Inkroche Taman Taman the weight of 100 berries was 200, 160 and 130 g, respectively, the mass of 100 seeds - 4.6; 3.1 and 2.9 g, the average weight of the pulp from the juice to the weight of the skin - 24.3; 19.5; 15.9. The percentage of pulp and juice in clusters of the studied varieties was 85,9-89,1%, and the ratio of pulp to juice to the solid residue 6,1-8,2. Yield of musts from the studied sample was 74,5-75,4%. The content of sugars in the berries (17,5-19,6 g / 100 cm3) was dependent on the yield, the characteristics of varieties and timing of the harvest, but the harvest was favorable for the production of beverages and wine materials

SIMULATION OF ATMOSPHERIC VORTEX FLOWS ON JUPIER AND SATURN
01.00.00 Physical-mathematical sciences
DescriptionAtmospheric currents on Jupiter and Saturn are characterized by turbulence and complex vortex structure, which is caused by a large angular speed of the gas giants. In this paper we consider two types of eddy currents - for hexagonal in the northern polar region of Saturn and the Great Red Spot in the equatorial region of Jupiter. For the numerical simulation of turbulent flows of this type the model of the planetary boundary layer was developed by the author. In both cases, the main strengthening mechanism is associated with geostrophic flow of small amplitude interacting with the planetary turbulent boundary layer. For hexagonal Saturn with its characteristic length scales and speed - 120 m / s and 14,500 km, respectively, there are more than 35 years data of observation. We have found that a small axial symmetry violation geostrophic flow in the shear causes the development of a hexagonal pattern in a turbulent boundary layer. In addition, under the influence of the Coriolis force and the eddy viscosity gradient in the turbulent boundary layer there is the jet formed, pressed against the lower edge of the layer. Great Red Spot on Jupiter has the characteristic velocity and length scales - 150 m / s, 14,000 km from north to south and 24000-40000 km from west to east, there are already more than 350 years data. It identified another mechanism of formation of vortex flow, coupled with the strengthening of small amplitude zonal flow in a turbulent boundary layer with the eddy viscosity gradient and the volume turbulent viscosity on a rotating planet. Both mechanisms are confirmed by numerical calculations of non-stationary planetary boundary layer

DescriptionThe impact of anthropogenic pollution on soil phytotoxity and on triticale plants in Vladikavkaz suburb was investigated in the work. The objects of the study were sod-gley leached soils and different varieties of triticale plants. The research was conducted in 2010-2011 at the Department of Biology of Gorsky State Agrarian University. The article gives data on microelements content in soils and plants within the range of influence of Vladikavkaz industrial enterprises. There was a marked change of miroelements’ mobility in soil and activity of their penetration into plants during fertilization. The sort characteristics of microelements’ accumulation in vegetative mass of triticale were researched. The conducted research is informative for soil and plant condition monitoring in anthropogenically polluted environment. The work indicates the increasing danger of microelements (including heavy metals) accumulation in soil and their inclusion in biological cycle in concentration that is too toxic for plants, animals and people during the usage of fertilizers, especially their high doses. The most dangerous among heavy metals are mercury, cadmium and lead. We used MPC rate of excess to estimate the content of these metals. The results of the research can be used in soil and cereal plant condition monitoring and diagnosis and in development of regional environmental regulation

THE INFLUENCE OF METHODS USED TO PREPARE FLAX SEEDS FOR PRESSING ON THE OUTPUT AND QUALITY OF OIL
DescriptionAnalytical survey has revealed that technologies of flaxseed oil processing used nowadays are able to produce technical flaxseed oil if the output is high and food flaxseed oil if the output is low. The objective of this work is to reason the most effective method to increase the output of food flaxseed oil while keeping its quality high. In this article a comparison has been made between single cold pressing of flaxseeds without preliminary preparation with microwave processing, as well as traditional (conductive) heating with traditional heating under vacuum. The object of the research is samples of flaxseeds (high quality variety VNIIMK-620 which contains 56.28% of linolenic acid in its fatty acid composition. It has been established, that the use of preliminary microwave processing enables to increase the output of oil compared to a single cold pressing without any processing, whereby the mass content of oil in oil cake can be reduced by 2.2%. At the same time the indicators of acid number and peroxide value are increased by 0,05 mg KOH/g and 0.37 mmol of active oxygen/kg correspondingly. Preliminary traditional heating of seeds before cold pressing enables to increase the output of oil, though not considerably, compared with preliminary microwave processing. At the same time the changes in acid number and peroxide value are similar to cold pressing with microwave processing. The use of vacuum when heating seeds in a traditional way does not influence the output of flaxseed oil but enables to decrease acid number and peroxide value to the level which is characteristic for the oil in original seeds. Thus, it is reasonable to use preliminary microwave processing under vacuum before cold pressing with the view to produce food flaxseed oil of high quality in terms of oxidative deterioration and the increase of its output

DescriptionWe have proposed the method of presowing processing of seeds of winter wheat using a hydrophobic paraffin-wax system of the new composition. Water protected paraffinceresin coating has been used before for storage of garlic. However, the paraffin coating were not applied to wheat seeds and were not investigated their effect on germination, growth and further development of plants of winter wheat. This work has been done for the first time. The ceresin wax is replaced by sunflower wax. New component composition of the hydrophobic waterproof coating winter wheat seeds: sunflower wax – 15-20 % wt .; paraffin – all the rest of it. Sunflower wax is a surfaceactive substance and has the properties of the plasticizer and the dispersant of the dispersed structure of the paraffin. The advantages of this coating: it protects the seeds from moisture loss, regulates the timing of their germination, contributes to the preservation of accumulated nutrients, and enhances plant growth and development; it increases the yield of wheat. In the field, we have set growth stimulating ability of paraffin-wax coating of winter wheat seeds of variety called Charade. The resulting increase in yield was 20% (control of 52.6 с / ha), while maintaining the quality of grain. This use of sunflower wax solves an important environmental problem – disposal of oilseed production waste

INVESTMENTS IN MILK PROCESSING AS A FACTOR OF IMPORT SUBSTITUTION
DescriptionEconomic and political conditions have a significant impact on the participants of Russian dairy market, which leads to a rise in the cost of attracting loans, a decrease in their investment activity as well as the efficiency of production and processing of milk. Special economic measures against a number of countries made it possible to relieve a niche in the domestic market by reducing the volume of imports of dairy products and should help in the building of its domestic production. The research results indicate the need to increase domestic production of milk and dairy products capable of equally competing with imports on quality and price with the support of the state. Our studies confirm the effectiveness of the implementation of investment project on organization of production of dairy products in Briukhovetsky district’s Ltd. "Harvest XXI Century". Through these measures, it will be possible to overcome the crisis in the shortest possible time and to ensure financial stability by boosting and expansion of existing production. As a result, the value of fixed assets of the enterprise will increase by 51 to 800 million. rub., the production facilities will be equipped with modern technological equipment, which has unique innovative features allowing to reduce the consumption of raw materials and automate the manufacturing process

MOTIVATIONAL MECHANISM OF INCREASING THE EFFECTIVENESS OF ECONOMIC MARKET AGENTS
DescriptionThe article discusses the monitoring of labor in the pilot organizations. The monitoring of labor indicates that nowadays it is particularly relevant to introduce organizational innovations in the field of staff remuneration in order to stimulate the proper production behavior. The article deals with the problems of innovative development of the employee’s motivation in an unstable economic development. The authors proposed the technique of information provision of the management staff with natural and value indices of labor resources generated in IFRS. An effective system of motivation of the personnel is of a particular importance in a turbulent economic environment, because in a competitive environment the employer views the staff as an essential resource that determines the success of economic market agents. The greatest attention should be paid to the staff training and saving valuable employees that enables organizations to achieve high financial results. The main aspect of the solution of many administrative decisions is a science-based system for obtaining timely, reliable and cost-effective information on the use of labor resources generated in the accounting and analytical base of the organization
