SELECTION OF PERSPECTIVE BIOLOGICAL CONTROL AGENTS FOR FALL WHEAT PROTECTION FROM FUSARIUM DISEASES
Description
The results of primary screening of bacterial strains on the basis of cell-wall degrading enzymes and antifungal activity against the fungus Fusarium graminearum. Selected active strains perspective for the development of biopreparations based on their type of multifunctional action to protect fall wheat from Fusarium pathogens are given

SIMULATION OF RADIATION EFFECT FOR DESIGNING THE ELEMENT BASE ON SCHEMATIC LEVEL
Description
The questions of construction of architecture for designing the universal and specialized element base, rack to influence of radiation are considered
-
Description
In this article, the deep relationship between the theory of automated control and system-cognitive analysis and its software tools - system of "Eidos" in their application to the intelligent control of complex systems is reviewed. Offered technology allows implementing in practice the intelligent automated and even automatic control of the objects of management, for which earlier management is realized only on weak formalized level, as a rule, without the use of mathematical models and computers. Such control objects include, for example, technical systems, the full quality-changing in the process of management, biological and ecological systems, socio-economic and psychological systems

Description
In this article, the direction of an improvement of the working process of roller-die pellet mills with a ring dies by butt restriction of wedge-shaped space by addi-tional contact surfaces is proved. The mathematical model of the process of pressure granulation (pelleting, extrusion agglomeration) of plant raw materials in the conditions of the closed wedge-shaped space between a die and each of press rollers is presented. On the ba-sis of the analysis of the mathematical model possi-bility of significant increase of capacity and decrease in energy intensity of pellet mills having additional contact surfaces in the form of restrictive rings is shown

MATHEMATICAL MODELING OF THE WORKING PROCESS OF LEVER BREAKER
Description
The dependences of the distribution of stump roots, allowing to model stump parameters to assess the difficulties of stumping are given, in requirements justification for stumping equipment. Based on the analysis of lever breaker working process, the differential equation of lever motion is got, which connects the moments acting on it and breaker performance modes and allows to set the parameters and modes of lever breaker in stumping of various sizes and species of wood

DEVELOPMENT OF HYBRID ALGORITHM ON A MODIFIED EXAMPLE OF THE SOLUTION OF TEST PROBLEMS
Description
The article shows the results of experiments to assess the effectiveness of multipoint and polygamous, which form the basis of the proposed mixed-evolutionary method, in comparison with known genetic methods

MATHEMATICAL MODELLING OF THE COMPRESSION PROCESS OF WOOD
Description
Rheological model for wood mechanical behaviour, viewed as a medium with dual porosity, is considered. Mathematical modelling of compression process of a wooden sample in a special mould is done at stable temperature conditions with the help of numerical methods. It is shown, in particular, that the durability level of essentially depends on the rheological characteristics of the structural skeleton and the wooden substance, as well as on reallocating of fields of moisture and porosity
