DescriptionIn peach orchards of the Russian humid subtropics, leaf curl is the most dangerous and harmful disease. Due to the high degree of danger from the peach leaf curl, for the first time in this region the main task was to analyze peach leaf curl development on weather conditions. In order to solve the problem, it is proposed to apply a new innovative intellectual technology: automated system-cognitive analysis (ASK-analysis) and its software tools - the “Eidos” system. In order to build the model, based on our own observations and the experience of Russian and foreign colleagues, it was decided to use the following factors: the sum of temperatures above +4 ° C of the current year (for the period from January to April), the sum of temperatures above +4 ° C of the previous year (for the whole year), the sum of precipitation of the current year (for the period from January to April), the sum of precipitation of the previous year (for the whole year), the number of hours of infection (in the current year). It was established that such factors as the number of hours of infection, the sum of temperatures above +4 ° C in April and during the period from January to April, as well as the sum of precipitation in March and April, are the most important in the dynamics of peach leaf curl development and spread. High rates of leaf curl spread and development are caused by the number of hours of infection in the range of 1440 ... 2064 hours, as well as by low air temperatures in March and April (the sum of temperatures above +4 °C – 89,4-240,4° and 283,7-316,7°, respectively) and high air temperatures - in January and February (the sum of temperatures above +4 ° C – 155,3-259,6° and 243,5-280,1°, respectively)

DescriptionIn the conditions of middle valley of the Lena River on the cryogenic, inundated, cespitose and chernozemic soils different steppe communities differently react on dietary regime. Herb-grass phytocenosis at organic dietary regime is reformed in cereal phytocenosis with the contents of cereals to 76% and bean types 19% of dry basis with productivity to 20 centner of hectare of dry basis. At the same time the efficiency of the improved phytocenosis was on charge exchange energy of 17,3 mega joule of hectare, feed units 1032 and a crude protein of 247 kilo of hectare. The whetgrasses phytocenosis has provided productivity to 19,4 centner of hectare and the content of perevarimy protein in 1 feed unit up to 118 gram. So the most effective for the steppe meadows is using complex fertilizer (humus of 20 tons of hectare + N60P60K60), increasing the productivity twice with a high quality of food

THE EFFECT OF PERLITE USING ON QUANTITATIVE AND QUALITATIVE INDICATOR OF SEED GROWTH
06.00.00 Agricultural sciences
DescriptionAn experiment has been carried out on the effect of germination of seeds with perlite on the improvement of the growth force of rye Vyatka-2. The purpose of the experiment was to study the effect of perlite on the growth force of seeds under the conditions of additional fertilizers and changing the volume water during irrigation. The task of the work was to determinate the growth force of seeds with perlite. The growth force of the seeds was determined after 10 days in sprouted seeds in five samples in glass vessels with three different moisture conditions. It was proved that germination of seeds with perlite increased the seed growth force up to 28% in comparison with seeds grown in sand (a control sample). The result also depended on decreasing of humidity rate up to 30-40%

MATHEMATICAL AND INSTRUMENTAL SUPPORT OF A POST-GRADUATE EDUCATIONAL PROCESS
DescriptionEducation was always an important part of the development of the individual and society, because education is the process of the formation of mind and character. Each level of education currently requires increased attention, since the quality of life of future graduates directly depends on the quality of the provision of educational services. Despite the fact that most of the educational process is formalized by educational standards, regulatory documents and local acts of educational institutions, this area continues to need both automation and the development of various models, methods and techniques, the use of which will greatly optimize the implementation of the educational process. There are few software products, models and methods that assess the quality of education and the educational process in general, aimed at individual elements of the educational system. In all the existing, basically, there is only support for working with bachelors, slightly less often with masters and very rarely with graduate students. This article describes methodological approaches to assessing the achievements of graduate students, as well as an information system for supporting the educational process of graduate school

TO THE QUESTION OF THE INNOVATIVE CAPACITY OF KUBAN
DescriptionThe article discusses the impact of the Olympic games in Sochi on the development of the information technology and innovation in the Krasnodar region. The authorities understand that the mere use of the Olympic legacy will not allow the region to hold the highest position in innovation activity, so in the field of the investment climate in the region there is a systematical work. However, in the innovation activities, their actions are fragmented. The article also notes that there is a tendency for the results of scientific research, which does not always meet the needs of the real sector of the economy. There might help the launch of the Western model of "science — business" in Russia, where business comes to the universities and raises scientific and technical problems. Therefore, the author proposes a solution to this problem by creating a triple helix "governmentbusiness-science". The meaning of which lies in the interaction of science, business and government, the latter would function as an information catalyst. The article provides an analysis of the basic indicators that characterize the state and level of development of scientific and innovation potential of the Krasnodar region. The article also discusses some reasons why the triple helix model is still not functioning

Description
Assessment of barley for the blotch incidence is traditionally carried out by visual determination of leaf damage with the help of the available expert – phytopathologist , and with the account scales which allows to characterize a variety for resistance or susceptibility to the studied disease in field conditions. This method has a number of disadvantages that are proposed to be overcome by developing a new tool of a phytopathologist. The measuring tool of a phytopathologist should provide high accuracy of the assessment of plants damage caused by the disease, and the measurement procedure should be quick and easy. The aim of this work is to develop a mobile tool of a phytopathologist for quantitative fast assessment of winter barley leaves damage caused by blotch in field conditions. To achieve this goal the following tasks should be fulfilled. Objective 1: introduce the idea and concept of problem solution; Objective 2: justify the choice of method and solution tool; Objective 3: apply the selected method and tool to solve problems, i.e. to perform the following steps: – cognitive structuring of the subject area; – formalization of the subject area; – synthesis and verification of models; – improvement of the quality of the model and choice of the most reliable model – solving diagnostics problems within the most reliable model (classification, recognition, identification), decision support and research of the simulated subject area by studying its model. Objective 4: describe the effectiveness of the proposed solution. Objective 5: examine the limitations and disadvantages of the proposed solutions of the problem and prospects of its development by overcoming those limitations and disadvantages. The article provides a detailed numerical example of the solution of tasks on real data processed with the ASC- analysis and "Eidos" system

THE REALIZATION OF GALOIS GROUPS BY TRINOMIALS OVER THE FIELD OF RATIONAL NUMBERS Q
01.00.00 Physical-mathematical sciences
DescriptionIt is known that not every finite group can be realized over the field of rational numbers as a Galois group of some binomial. In this connection, a more general question arises: suppose that there is given a finite transitive subgroup G of the symmetric group S on n symbols; Can this group G be realized as a Galois group of some trinomial of degree n over the field of rational numbers? In this paper we prove that every transitive subgroup of the group S can be realized in the form of the Galois group of a certain trinomial of the degree n, for the values n = 2, 3, 4. For n = 5 , 6 we give examples that realize concrete Galois groups. In the case n = 7, all the transitive subgroups of the group S are realized, except possibly one group of the isomorphic dihedral group D. Further calculations will be directed to the realization of specific Galois groups for n = 8, 9 ..., however, the number of transitive subgroups of the group S for n = 8, 9 ... grows very fast, so the larger the value of n, the more difficult it is to realize not just everything but the specific subgroup of the group S in the form of a trinomial over Q
