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. Numerical solutions of equations
system of turbulent transport of admixtures in a surface
layer of the atmosphere for a large scale have
been studied

In the article results of a comparative study of technologies of cultivation of sunflower with application and without application of herbicides are resulted, and also their economic assessment is given
The article motivates the reasoning and creates the methodological fundamentals of interpretation efficiency of the compound systems in a form of the circumstances of steady market positioning products. These circumstances include both an opportunity of existence of equilibrium among “market players” and current market share as the complex criterion
Article investigates the questions of development strategy of small metal trading firms using the methods of economic-mathematical modeling and methods of forecasting. Predictive calculations were performed on example of one particular enterprise, for different demand scripts: pessimistic, optimistic, inertial and aggregated
In the article the results of the comparative analysis of economic efficiency of integrated and disintegrated systems of grain manufacture, its processing and realization of bread are shown
Soil bioassay and soil herbicide contamination are reviewed in this paper. The parameters for toxicity detection in soil and different test-systems are discussed
In the article the questions of grape plantings spareness elimination by the ways of filling-up saplings with cuttings of scleroticе rods, green arms or a bush and reinoculation of bushes. With the preventive purpose, for reduction of plantings spareness degree on a vineyard, stamping of arms, application of potash fertilizers in the summer and in the autumn, stopping of watering in due time, normal loading of bushes with a crop and harvesting in due time are done, i.e. all the conditions for the best ripening of a rod and preparation of plants for winter are made
In this article the size of material stream in bread-production chain with use of the theory of indistinct sets and application of risk component is predicted, the interval model of definition of efficiency is developed
The analysis of post-modernist discourse’s features in the context of modern philosophical ideas has been reviewed in this paper. Irony has been viewed as a particular tool of the author’s opinion realization and the didactic influence upon the reader
