DescriptionThe results of long-term population-genetic studies in wheat pathogen system “wheat – dangerous disease pathogens” associated with the study of the structure, variability, forecast of plant pathogen development and the host plant genetic diversity are introduced. It is shown that it is necessary to develop polymorphic genetic disease resistance of plant populations to rehabilitate the agroecosystem phytosanitary state, which is possible only on the basis of broad genetic diversity of source material, taking into account the intraspecific differentiation of pathogens and tendencies of the changes

The influence of technology on the fortification composition of biologically active substances of wine and the Cahors beverage type has been examined. We have also established and explained the dependence of the content of phenolic compounds, including carboxylic acids from the ways of alcoholization. A way of fortification, contributing to the enrichment of wines and beverages such as Cahors with biologically active substances has been shown

THE METHOD OF CONSTANTLY OPERATING MODELS IDENTIFICATION FOR QUALITY CONTROL OF STUDENTS KNOWLEDGE
DescriptionBased on the theory of self-organization, we have developed an original method for identification of target functions students’ knowledge quality (SKQ) in the face of influencing factors uncertainty. The proposed system of external criteria for the models selection and control parameters allows to use the model for the effective management of the SKQ

Description
The negative economic consequences of using sun-flower seeds infested by molds Phomopsis helianthi Munt. Cvet. et al. as inoculums are described in the article. The necessity of finding the ways of these molds inactivation alternative to the way of chemical disinfection, and the advantages of usage of electro-physical ways of seeds’ treatment for this purpose and in particular electromagnetic field (EMF) of microwave frequency (MWF) are explained. The construction of the laboratory experimental setup is shown, on the bases of which the process of Flagman variety of sunflower seeds disinfection EMF MWF is researched. The testing technique is described too. The observable sowing sunflower with the starting infection rate by phomopsis at 22% is treated for different durations in the EMF MWF, being in either static or continuously mowing layers. As result of these experiments the particular rates of treatment providing the total disinfection of sunflower seeds from molds Phomopsis helianthi Munt. Cvet. et al. are revealed and the discovered contradictions in the experiments’ results are explained

Description
The article describes the details of modeling of catalytic systems for the production and conversion of energy in anaerobic digestion of organic manure. We have also presented a simulation mathematical model that establishes the relationship between structural and technological parameters of catalytic systems and the parameters characterizing the efficiency of the catalytic system in the production and conversion of thermal energy in the anaerobic treatment of organic manure
