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

On the basis of the analysis of morphological indicators of wood cultures of a linden it was recommended to start caring cuts of cultures (the combined method) with removal from low ranks of trees in diameter at height of a breast to 8 sm and from high ranks of 4 trees (24 sm). Intensity of cuts - 35 % from the general number of trunks and 15 % on weight
