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

THE RESEARCH OF VITIS SILVESTRIS GMEL. IN THE NOTHERN CAUCASUS
06.00.00 Agricultural sciences
DescriptionVitis vinifera subsp. silvestris Gmel. is the wild subspecies of Vitis vinifera L. and an important source of genetic resources for grapes breeding. Currently, this form is very rare in the world. In this paper, conducted the first study of wild grapes which was found in the North Caucasus with the use of two microsatellite markers. The study have shown a high level of genetic diversity: intrapopulation variability was 75,2%, the interpopulation variability accounts was 24,8%. All populations are characterized by certain unique genetic structure and may be as donor of resistance genes which have a long-term evolutionary selection

Description
The approach to the solution of resource allocation problem in the process of activity planning for research and development organization having sufficient scientific and design capacity is considered. This approach enables to solve complex resource allocation problem in the context of designing division of work and network team building and project implementation technology, using software intended for solution of traditional linear programming tasks. Database modeling technique with account of specific characteristics of this approach is described

AGRO-INDUSTRIAL HOLDING INITIAL DATA AND THE PROGRAM INTERFACE OF DATA STANDARDIZATION
DescriptionIn this article the initial data for construction of two-level semantic information model of agro-industrial holding management is analyzed, the problem of their automated transformation to a state which is directly perceived by the AIDOS system by means of one of its standard interfaces is raised and solved. The algorithm and a source text of the program ensuring these functions, and also the results of its work and automatically generated directories of classes and factors by the AIDOS system on their basis, and also training sample for the particular models forming a part of the two-level semantic information model of agro-industrial holding management are resulted

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

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

SYSTEMIC COGNITIVE APPROACH TO AGRO-INDUSTRIAL HOLDING MANAGEMENT
DescriptionIn the article the management problem of agro-industrial holding is formulated in a general way, which is, on the one hand, it is necessary to produce recommendations about holding management, where its adaptive model is necessary, and, on the other hand, the construction of its model is inconvenient because of high complexity and dynamism of internal logistics of the object of management, its territorially distributed and diversified character, a large quantity of the economic indicators characterizing its activity at various levels of its organization. The general method of the decision of the formulated problem by using the systemic cognitive approach is offered
