OUT-OF-ROOT FEEDING AS THE WAY OF INCREASING OF ADAPTABILITY OF WINE PLANTS TO SANDY SOILS
06.00.00 Agricultural sciences
DescriptionResults of research of influence of foliar top dressings by Zitovit and Zircon preparations on development of plants of grape of Berlandieri × Riparia Kober 5ВВ grade on sandy soils are submitted. Processing of plants with Zitovit in conditions of their insufficient mineral nutrition through roots, improved their growth and development. Action of Zircon preparation for raising immunity promoted qualitative rearrangement of morphological parameters of development of plants

EXTRACTION OF DNA FROM HERBARIUM LEAVES VITIS VINIFERA L.
06.00.00 Agricultural sciences
DescriptionTwo methods were used for DNA extraction from herbarium leaves of two subspecies: V. vinifera subsp. sativa D.C. и Vitis vinifera ssp. silvestris Gmel. DNA extraction is difficult from herbarium leaves plants because of the presence of metabolites that interfere with DNA isolation procedures and downstream applications such as DNA restriction, amplification, and cloning. The quality of DNA was checked on a spectrophotometer by measuring the level of absorption at A260/280 nm. The results showed the successful extraction from mature and dried leaves of DNA when using the СТАB-method №2. Another method hasn’t shown satisfactory results in amplification of DNA

Description
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

THEORY AND CONSTANTS OF WALL TURBULENCE
01.00.00 Physical-mathematical sciences
DescriptionThe 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. The estimated mean velocity, temperature and impurity concentration profiles as well as the spectral characteristics of the streamwise velocity component are to be shown in a good agreement with the experimental data

SIMULATION OF TURBULENT TRANSPORT IN THE ATMOSPHERE PARTS 1, 2
01.00.00 Physical-mathematical sciences
DescriptionThe 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

TURBULENCE THEORY AND ROUGHNESS DENSITY EFFECT MODEL
01.00.00 Physical-mathematical sciences
DescriptionThe model of the turbulent boundary layer over a rough surface is presented. The model is based on the special type of transformation of the Navier-Stokes equation. The turbulent boundary layer in this model is considered as a flow above the rough surface gener-ated by the viscous sublayer (the dynamic roughness effect). The roughness density effect on the shift of the mean velocity logarithmic profile has been estimated in the case of 2D and 3D roughness elements
