01.00.00 Physical-mathematical sciences
DescriptionArticle is devoted to the numerical analysis of regional problems for system of the equations of Nernst-Plank-Puasson (NPP), to application of these regional problems to modeling and studying of mass transfer in the channel desalting of electro dialysis device. Various mathematical models of the transfer of ions in potential static mode in the form of system of the quasilinear equations with private derivatives are offered. The basic rules of occurrence and development of a spatial charge in the channel desalting of electro dialysis device are revealed

TENDENCIES AND PROSPECTS OF DEVELOPMENT OF CREDIT FINANCING OF AGRICULTURAL ORGANIZATIONS
DescriptionIn this article, generalization of managerial process by gathering extra means is resulted; principles of management are shown by formation of the extra capital; the concept financial leverage, effect financial leverage and a technique of its calculation is resulted; look-ahead change of effect financial leverage at the expense of influence of optimum structure of the capital of some agricultural organizations of Krasnodar region is calculated

IMPACT OF THE GLOBAL CURRENCY AND FINANCIAL CRISIS ON THE GLOBAL FOOD SITUATION
DescriptionFood security of the population is now one of the major policy goals of the world community and individual countries. In the context of the global currency and financial crisis, that hit the economies of many countries, food security is particularly important. The article examines the current state of world food situation, highlighted the reasons for the crisis in this area. The authors defined the institutional framework of supranational regulation of food relations in the form of an international organization that is designed to provide the best of the Food Balance between the two countries through efficient production and distribution of agricultural raw materials

RUSSIA STARTS IN WTO: FORECAST OF THE ECONOMIC SAFETY
DescriptionThis article investigates the political and economic peculiarities of Russia in the World Trade Organization. Examines trends of possible threats to Russia's economic security. The necessity of constant monitoring of Russia's economic security and a member of the WTO is shown

Description
In this article, the direction of an improvement of the working process of roller-die pellet mills with a ring dies by butt restriction of wedge-shaped space by addi-tional contact surfaces is proved. The mathematical model of the process of pressure granulation (pelleting, extrusion agglomeration) of plant raw materials in the conditions of the closed wedge-shaped space between a die and each of press rollers is presented. On the ba-sis of the analysis of the mathematical model possi-bility of significant increase of capacity and decrease in energy intensity of pellet mills having additional contact surfaces in the form of restrictive rings is shown

MAN AND HIS WORLD-ATTITUDE. REPORT 3. WORLD-ATTITUDE, ABILITIES, NEEDS AND TYPES OF HUMAN INTEGRITY
DescriptionThe article is devoted to analysis of the relationship of world-attitude of man with his abilities, needs, and inherent of its integrity the types. The features of these relations suggest that the totalitarian and partitive types of human integrity are implemented in passive-somacentric, active-somacentric, passive-personacentric, active-personacentric, passive-spiritocentric and active-spiritocentric subtypes, and a harmonic type of this differentiation is not typical

Description
The article, on a simple numerical example, deals with the application of the automated system-cognitive analysis (ASC-analysis) and its software tools - intellectual systems "Eidos" for the detection and investigation of determination of emergent macro preferences of systems in their composition and hierarchical structure, i.e. the sub-systems of various complexity levels (levels of the hierarchy). The article briefly discusses some of the methodological issues of creation and application of formal models in scientific knowledge. The system generalization of the principle of William Ross Ashby about the necessary diversity on the basis of the system of generalization of the theory of sets and systems theory, information, generalized formulation of the principle of Galileo-Einstein, the hypothesis about its relationship with the theorem of Emmy Noether are offered; and also there is a hypothesis "About the dependence of the force and direction of the relations between the basic elements of the system and its emergent properties as a whole, on the level of hierarchy in the system"
