This article gives change estimation of conditions of external debts of the Russian Federation to nonresidents in the conditions of an economic crisis and influence of the given changes on debt stability economy of the Russian Federation. External debts of the Russian Federation to nonresidents, indicators of debt stability of the Russian Federation are considered on the basis of the data of the state statistical and budgetary reporting, the statistical data of the Bank of Russia, the Ministry of Finance of Russia, other information regarding an external debt of the Russian Federation

Description
In the article, it is shown that stability of the enterprise is a complex concept. For an objective estimation of level of steady economic development, it is offered to use a technique on base of criteria indicators. The technique is tested at the enterprises of Stavropol region

MATHEMATICAL MODELING OF ANTIBACTERIAL IMMUNE REACTION
DescriptionThe work describes the mathematical model of an antibacterial immune reaction, which is presented as a system of integraldifferential equations. The global characteristics of the adequacy of the model to the real process are studied

DescriptionThe review of resolvability of the beginningboundary problem describing dispersion of an impurity in turbulent atmosphere, correctness of mathematical models, describing impurity dispersion in atmosphere and Koshi’s problem, the first right problem, the third right problem is given in the article

Description
As result of evaluation 24 common wheat introgression lines with genetic material Agropyron glaucum the considerable variability of resistance to leaf rust was revealed. Genetic control of leaf rust in introgression lines 60 and 109 was studied using hybridological analysis. Both lines contained single dominant genes differed from each other and from the known effective Lr19 and Lr24. The investigated lines with genetic material Agropyron glaucum are valuable donors of the genes for leaf rust resistance

LOWER DON SOILS STABILITY TO HEAVY METALS CONTAMINATION
DescriptionThe mathematical model of soil stability to heavy metals contamination is proposed. The Lower Don soils contamination with Cu, Pb and Zn was calculated

FORMATION AND DEVELOPMENT OF INSTITUTIONS OF LAND OWNERSHIP AND LAND USAGE OF PFF
DescriptionThere was shown that the low degree of development of institutions of land ownership and the land usage and noneffectiveness of institutions of state regulations of land market lead to the underestimation of land as an asset, mispresent the reproduction mechanisms, rent relations and dividend policy of agrarian enterprises as well. On the examples of some peasantfarmer households of Krasnodar region there was substantiated that the assessment of agricultural lands and its inclusion in an authorized capital of an enterprise allow to increase its assets, to rise the financial stability and liquidity of farming subject
