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

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

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

METAMODELING IN THE SYSTEM OF KNOWLEDGE OF ECONOMIC REALITY
DescriptionThe role of modeling in the knowledge of economic reality and the formation of economic theory is shown. Informational, instrumental, and communication functions of the models are the most important ones in the process of understanding of economic reality. The urgency of increasing knowledge on economic models and process of modeling of economic objects is proved. In this regard, the need to address a number of issues that are related to the field of economic metamodeling is noted. The definition of economic metamodeling as a field of knowledge and activities associated with optimal formalization of the philosophy, methodology and practice of development models of functioning and evolution of the economy is given. Economic metamodeling is considered as an important factor in ensuring maximum adequacy of the economic theory developed on the basis of the wide use of models of the economy and society as the object of modeling and research. The ideas about philosophical, methodological and methodical bases of modeling of economic phenomena are outlined; the purpose and objectives of the economic metamodeling are defined. Such principles of economic modeling as basing on the common philosophical and methodological basis presented in the metamodel of social economy, recognition of the subordination of economic models based on structural and functional hierarchy, pragmatism, reality of the economic models, the unity of semantic security models, and the optimality of the layout models are formulated. The task of developing of economic metamodel of the society and the metamodel of economic modeling is done

TECHNOLOGICAL WAYS IN INNOVATIVE DEVELOPMENT OF ECONOMY
DescriptionIn the article we consider problems of transition of an economic system to the new technological way. Success depends on degree of readiness of system for institutional changes and availability of necessary resources. Assessment of a condition of system plays an important role in the choice of management decisions on its upgrade. Delay with transition to new technological way or, on the contrary, its stimulation in system, not ready to changes, leads to serious, negative consequences for the reformed economy. Change of technological way leads to the release of capital which goes to the financial markets, entering crisis chaos into the system. The task of the state consists in timely reaction on developed, during transition to new way, a situation and the direction of financial flows in key technologies of new way. The new system of assessment of a condition of system and a stabilization effort is offered during the change of technological way

TO THE QUESTION OF ORGANIZATIONAL STRUCTURE OF GRAIN BUSINESS MANAGEMENT
DescriptionIt is noted that the grain market has a key influence on food supply in our country. Today, in the conditions of import substitution, many animal products continue to be received from abroad in large volumes, among which grain is a feeding base, although those products can be produced domestically with high profits. In recent years, our country has become a large grain exporter and had been set among the four world's largest grain sellers at the world market. Now, the main problem of the grain business has become not manufacturing but the effective management and marketing of grain sale on domestic and foreign markets. Under the "grain market", the authors understand an integrated mechanism covering the entire process of production - processing - logistics - marketing of grain products, ensuring access to the consumer. The authors note that today there should not be rigid boundaries in the management segments of the grain market, as all sectors of the market are technologically linked through a set of integrated activities. Also they are bringing up their model of functioning management of the grain market, which clearly demonstrates the basic blocks of the investigated production systems, their connections and relationships. The practical implementation of such cooperation promises to participants of the grain market to get a certain synergistic effect due to the systemic functioning of technological, logistics, marketing and other business relationships between all parties; as well as adjustments to price ratios and more sophisticated economic instruments for investment in that business

ANALYSIS OF FUNCTIONING OF RAILROAD WAREHOUSE OF MINERAL FERTILIZERS
DescriptionThe railroad warehouse has most important role in the delivery process of fertilizers to agricultural consumers. It acts as logistics intermediaries. The analysis of material flows has been done on the example of a typical provider of mineral fertilizers in the South of the Rostov region (CJSC «Zernogradagrohimservis») for the last 6 years. Income values and implementation values are varied during the year synchronously for all fertilizers types with the exception of a few months at the beginning and the end of the year. During most of the year the enterprise operates as a negotiable warehouse. In January-February and October-December ammonium nitrate accumulates as a seasonal inventory for the spring peak of implementation, in the rest of the year its reserves are insurance. Stocks of other fertilizers types are insurance stocks for most of the year, in May-July occurs a slight accumulation of their seasonal stocks. A significant portion of mineral fertilizers (especially ammonium nitrate) is delivered for small enterprises and individual farms by cars of this provider. According to the supply contracts, a one-car-run is performed for the vast majority of customers. Routes of delivery of fertilizers are either radial or pendulum (with reverse idle mileage). Therefore, the optimization of the delivery of fertilizers does not seem possible by methods such as obtaining the shortest route network, consolidation of suppliers for consumers, etc.

10.00.00 Philological sciences
DescriptionThe article aims to show the problems, which a researcher has to face during the analysis of the Thieves’ Law. The Thieves Law is considered as a synthesis of texts that can be decomposed into subsets of smaller texts. The originals of such texts in various languages were lost, and their later translations and compilations made the analysis more difficult. The synthesis of such texts is viewed through the prism of generally understood Kabbalah, and the main principle is an esoteric search for the "inner sense" that is based on the algorithms and stereotypes in criminal activity. The mental spaces of legal law and religious systems give a reference space of the Thieves Law by such approach. The parts of such mental spaces contradictory to others are removed from this reference space. Not only words but also phrases, sentences, texts, and even sets of texts, any multilevel signs at accidental and planned asymmetry in form and essence become codifying elements in sources full of allegory and parable. The analysis is based on a synthesis of views by L.N. Gumilev, U. Eco, and O.V. Leszczak

DescriptionIn the article we investigate the multicriteria task arising at the organization of distributed calculations in a corporate network. As a mathematical tool to solve the problem we use prefractal graphs, which naturally reflect the structure of relationships in global and corporate networks. The corporate network with the distributed computing system at the solution of a particular task has to be reliable, quickly and qualitatively to make decisions. And every computer in the network should be a part in the solution of the problem, since it is fixed for a certain function. The problem is reduced to cover the prefractal graphs with disjoint simple paths along the edges and vertices. On the set of all admissible coverings we constructed a vector-target function with specific criteria. All these criteria have a specific meaningful interpretation, allowing organizing the calculation of maximum reliability, with minimum time information processing and loading balancing between the network elements. In the article we constructed polynomial algorithms for finding optimal solutions according to specific criteria. For the criteria which are not optimizing the allocated coverings, estimates of the lower and upper bounds are given. For all the algorithms we constructed and substantiated estimation of computational complexity, confirming the advantage of using algorithms on prefractal graphs to classical algorithms on graphs
