REFORMING OF PETROLS BY ELECTROMAGNETIC FIELD
01.00.00 Physical-mathematical sciences
Description
Influence of electromagnetic field on petrols, which leads to the decrease of their physic-chemical parameters and temperature of flash are considered in the article as well, and therefore to increase the calorific capability of fuels.

Description
Main scientific results, which were received in 2007 under creation and investigation of semantic information multi mode, providing as detection of dependence between astro signs and accessory of respondents to generalized social categories as a use of knowledge of these dependences for identification of respondents by these categories are casted in the article. Multi model includes 172 private models on 37 generalized categories and each of categories is presented less than 1000 respondents under general fetch capacity of 20007 respondents. It was applied the method of systemic- cognitive analysis, which is considered as one of the universal variants of decision of thirteen problem of Gilbert in practice ( theoretically this problem has been done in the theorem of A.N. Kolmogorova, which is a generalization of theorem V.I. Arnold ( 1957) under it.

SOIL FERTILITY IN DEPENDENCE ON CROP CULTIVATION
06.00.00 Agricultural sciences
Description
Results of researches carried out in stationary multi factorial experience, plotted in 1991, were generalized in the article. Different influence of cultivated crops in crop rotation on agro physical properties of active fertile layer of old irrigated leached chernozem was determined on the base of material generalization. Positive role of alfalfa for improvement of agro Physical soil properties were revealed. Quantity of agronomically valuable aggregates and water proof of soil structure are increased because of it.

ENERGY-SAVING METHODS OF CROP CULTIVATION UNDER IRRIGATION IN ARID STEPPE ZONE
06.00.00 Agricultural sciences
Description
Data of many year researches on influence of cultivation methods ( main soil cultivation, fertilizers, irrigation methods) on physicochemical properties of common black soil, growth, development, crop productivity, their economical and energetic effectiveness in the conditions of arid steppe zone of Rostov region were positioned in the article.

EFFECTIVE CROP ROTATIONS AND STRUCTURES OF CROPS IN THEM UNDER IRRIGATION
06.00.00 Agricultural sciences
Description
Eight-year research data of crop rotation of new six-field crop rotations and energy-saving methods of their cultivation are presented in the article. More productive grass- grain ploughing crop rotation and energy-saving means of main soil cultivation, rates of fertilizers and regime of irrigation, increasing productivity of agricultural lands, keeping fertility and biodiversity of irrigated agro landscapes were revealed.
-
Description
Organization questions of intracorporative (intraeconomic) interaction of enterprises-participants of agro holding are considered in the article. Main system constituents of intraeconomic relations in agro holding structures were separated out. Main variants of mutual calculations between participants of agro holding were systematized, main problems of intracorporative distributional relations were identified.

DETERMINATION OF LEASE FOR LAND AND REAL ESTATE
Description
Main approaches of determination of price approaches of real estate objects are analyzed and mass assessment of land is considered step-by-step. Stations of technical service (STC), located in Krasnodar, are used as the objects of research.
-
Description
Results of internal environment integrated production system research with the point of view of qualitative analysis and risk evaluation were casted in the article. In particular, model and method of calculation of integral index of production vertical line risk and improved data-flow model of effectiveness assessment of IPS with an account of risk constituent on the stage of creation of material flow are described. Reasonability of presentation of prognostic meaning of profit in the type of indistinct triangular number was substantiated.
-
Description
Model and method of calculation of integral index of influence of external environment of integrated production system were considered and interaction of given index with choice of optimal strategy of business-system development was shown in the article. Results of approbation of worked out model and method were casted.
