01.00.00 Physical-mathematical sciences
01.00.00 Physical-mathematical sciences
Description
In the article with the help of a technique, based on discretization initial problem of time variable and the method of basic potentials, is constructed the approximate solution of the second two-dimensional problem for the equation of diffusion with depending on concentration coefficients and source function. The general view of the approximate solution of this problem is reduced. On concrete example convergence of the approximate solution of the problem to the exact is shown

THEORY OF TURBULENCE AND SIMULATION OF TURBULENT TRANSPORT IN THE ATMOSPHERE PART 4
01.00.00 Physical-mathematical sciences
Description
The completely closed model of wall turbulence was derived directly from the Navier-Stokes equation. The fundamental constants of wall turbulence including the Karman constant have been calculated within a theory. This model has been developed also for the accelerated and non-isothermal turbulent boundary layer flows over rough surface

01.00.00 Physical-mathematical sciences
Description
Numerical solutions of equations system of turbulent transport of admixtures in a surface layer of the atmosphere and for a large scale have been studied

ABOUT SHAPING THE THERMAL RADIATION IN OPTICALLY TRANSPARENT SOLID OBJECTS
01.00.00 Physical-mathematical sciences
Description
It has been experimentally proven that thermal radiation of optically transparent solid objects forms from the entire heated volume within the spectral frequency that is allowed to pass through

FLOOD - CONTROL SYSTEM AT AGRI-CULTURE'S SERVICE
Description
Role of flood - control system on Low Kuban River for protection of agricultural lands from dangerous impact of waters is analyzed in the paper.
-
Description
In article the flooding and rehumidifying tendency of the lands in Krasnodar region is estimated. For re-vealing of the reasons conducting to growth of the sizes of the rehumidified lands and definition of ways of land improvements of the rehumidified lands it is necessary to establish the factors of the influence causing distribution of the rehumidified lands

PECULARITIES OF SYSTEMS OF AGRI-CULTURE OF NEW GENERATION OF THE KRASNODAR REGION
Description
In article the retrospective analysis of systems of agriculture is resulted, leading to track evolution of principles of their construction. The main distinctive feature of systems of agriculture of new generation is the strengthened ecological orientation

FORECASTING ESTIMATIONS OF ECO-LOGICAL CONSEQUENCES OF FRESHET ACTIVITY IN POOL OF THE RIVER KUBAN
Description
In the article estimations of catastrophic flooding for the last years are given, and also the actions planned for prospect on unwater are given protec-tion. Damages from flooding are estimated in eco-nomic and ecological terms
