Description
Professional apple gardening is bound to particular risks, of which is essential losses of a harvest because of diseases. An apple scab, the caused Venturia inaequalis (Cooke) G. Winter, brings the greatest loss. The main approach in monitoring of a scab of an apple-tree is creation of grades, steady against pathogen. In the present work we have carried out phytopathology testing of generations of the seedlings received from the free pollination of six forms of a crab of Malus orientalis from a collection MOS VIR (Maykop) characterized by a relative resistance to the apple scab in 2-3 classes of damage by long-term data. For infection we used inoculum, consisting both of natural population of a scab, and of strains of pathogen of various cultivars and geographical origin. When carrying out padding infection increase in force of an infectious background that can be bound to selection of the plants of biotypes of a fungus that are most adapted for genotypes was noted. It is recommended for precise elimination of unstable plants at selection at early stages of an ontogenesis to carry out more than one serial infection during the season. By results of the phytopathological testing, we highlighted three Malus orientalis forms from the six studied No. 17982, 17985 and 3080 the most perspective stability genes for an introgressiya in a cultural gene pool of an apple tree

EVALUATION OF THE QUALITY OF EDUCATION OF STUDENTS AND EFFECTIVENESS OF TEACHERS
DescriptionModern universities do not have effective techniques for evaluating the quality of education of students and effectiveness of teachers' activity that allows controlling and directing its activities. We have proposed to perform the quality evaluation of students preparation based on the results of intermediate assessments, examinations, and test results of the teachers, who held their classes. The article provides analytical expressions for calculating the quality of the current preparation of students and the quality of education of graduates, the effectiveness of teachers in core activities (educational, methodical and scientific work). In assessing the quality of education, we have considered the learning outcomes, employment potential, i.e. educational and labor activity. The proposed techniques will increase the objectivity of the assessment of the quality of graduates’ education in technical universities and the effectiveness of teachers. This will allow us to make changes in the organization of educational process and the content of working programs of training, educational and methodical and material and technical support, to change the contents and technologies of improvement of qualification of the teaching staff that will contribute to increase demand for graduates in the labor market

Description
The article examines the key aspects of import of food in Russia at the present stage. The relevance of this problem is necessary to the development directions of rationalization of import substitution, under condition of increase of competitiveness of domestic agricultural producers. The importance of this problem increases in recent years due to sanctions and embargoes, highlights the need for comprehensive studies in the formation of commodity composition of import substitution of food products and determining the key factors of its regulation. The work presents the analysis of dynamics of volume of imports of foodstuffs and agricultural raw materials for their production and its diversification based on import substitution. We discuss main commodity groups of food and, in particular, crop production and viticulture. In addition, we examined the major groups of goods from the point of view of the potential and opportunities for import substitution and selected those items, which, for various reasons, cannot be carried out in the Russian conditions due to climatic and other factors. As a result of the study, the authors concluded that the introduction of anti-Russian sanctions and the retaliatory embargo on imports of foreign agricultural commodities in general had a positive impact on the development of the domestic agricultural business, which is confirmed by the indices of growth of agricultural production in recent years. In addition, if there is further adequate funding of this sector, it is possible to speak about prospects of strengthening of food independence of Russia

FEATURES OF MODELING OF TECHNOLOGICAL OPERATIONS OF AGRICULTURAL RAW MATERIALS PROCESSING
DescriptionThe ways of improving the work of food enterprises during processing of agricultural raw materials on the basis of a system analysis of the durations of technological operations are considered. The basic mathematical models of technological processes have been analyzed and the possibility of using unified technological operations to predict the time of completion of work has been shown for processing various pairs of raw materials. It is established that the construction of mathematical models of technological processes of processing of agricultural raw materials should be based on using the potential of transfer of the target component between isopotential surfaces. This allows not only to unify the created models of technological processes, but also to significantly increase their extrapolating ability to estimate the durations of technological operations

Description
The article explains that the formation of new content and forms of professional training of future teachers in higher education institution must be implemented with emphasis on its ability to self-development, but rather, on professional and personal self-development. This work discusses the following areas that characterize the professional and personal selfdevelopment of future teachers of mathematics: the organization of the educational process with a strong orientation to future teachers of mathematics; integration of educational technologies of selfdevelopment of personality of students – future teachers of mathematics, aimed at formation of skills of independent educational activity, ability to selfeducation; formation of professional communicative competence of future mathematics teachers both through traditional means of communication in the educational process, and through remote (computermediated communication); the actualization of reflexivity of personality of future teacher of mathematics; the development of the requirement of motivational sphere, based on professional motives and interests, willingness to self-improvement in professional activity. It is shown that the process of professional and personal self-development of future teacher of mathematics in the educational process of a university will be efficient if all of these areas will manifest themselves together, inseparable from each other

EXPERIENCE OF SCREW ROTORS DEVELOPMENT AND DEPLOYMENT
DescriptionThe article offers a method of details finishing and cleanup processing based on the details and working environment granules mass hashing in combination with the target transporting movement from loading to unloading. Such combination is provided by means of technological process in which the movements are carried out at the expense of the working body executed in the form of a complex screw rotor with the multidirectional screw surfaces formed by flat elements. Four screw rotors designs and methods of their assembly as well as the recommendation on the use of screw rotors are shown: "The movement of the processed details and particles of a working environment is the most complex and infinitely various among the I class screw rotors and the most elementary and uniform among the IV class screw rotors". The practice and experimental control of the details finishing technological process introduction efficiency in screw rotors have shown that for the considered case productivity of, for example, agnail removal increases tens of times. It is reached not only at the expense of the possibility of continuous processing provision in screw rotors, but also due to significant increase in amplitudes of low-frequency fluctuations which are reported to loading masses by the screw rotors machines located at different angles to each other and to screw rotor rotation axis
