Description
The results of laboratory experiments on the effect of different concentrations of SkQ3 (10- (6'- methylplastoquinonyl) decyltriphenylphosphonium) on the rate of growth of spring barley seedlings of varieties Sokol and winter wheat varieties Kalym in normal and under inadequate moisture conditions, as well as data from field experiments on the effect of pre-sowing processing SkQ3 on the morphometric indices of spring barley varieties Shhedry, hard winter wheat of the Lazurite variety and soft winter wheat of the Lydia variety are presented. As a result of laboratory experiments, an increase in the growth rate of 14-day-old seedlings grown in solutions of polyethylene glycol was shown when treating the seeds with 2.5 nM and 25 nM with SkQ3 solutions. In the field experiments on the pre-sowing treatment of SkQ3 seeds, an increase in the morphometric indices of spring barley varieties of generic Lydia soft winter wheat and hard Lazurite winter wheat has been established, as well as an increase in the yield of winter wheat of both varieties as compared to the control

LOGICAL PRICE ESTIMATION OF THE RUSSIAN FEDERATION EDUCATIONAL LANDSCAPE
DescriptionIn the given article, we describe an approach to the formation of learning environment optimal structure based on logical price tools using through statistical assessment of universities rank distribution. The actuality of this approach is based on the analysis of modern methods to the formation of the university landscape and assessment of a number of systemic problems of universities’ structure transformation, which consists in the disproportion reinforcement and reducing the variety of educational programmes and research schools, which prevents its effective development. The postulates of institutional university transformations based on the pragmatic paradigms providing stability and progressive development of the system in its self-development and evolution process are proposed as a methodological concept of using the statements of the cenoses theory. The logical price analysis of the Russian universities structure in 2015 conducted above has confirmed the proposed hypotheses, showing statistical coupling of university environment elements, their relatively systematic instability and structural imbalances. The educational system assessment as a cenosis allowed to reveal points of the required impact factor, state intervention direction in the distribution structuring, possible limitations associated with the implementation of large universities support programmes. The proposed approach has a high level of reality objective assessment and may be used when making long-term strategic decisions

OBJECTIVES AND METHODOLOGY OF CROSS-CUTTING DESIGN OF TECHNICAL SYSTEMS
DescriptionThe debate continues about reform of higher education In the country. We offer our point of view regarding the preparation of bachelors and masters on the direction of "Control of the technical systems". Department of automatic control systems leverages variable disciplines of specialization and optional subjects, forms a curriculum based on the needs of the business environment of the region or commissioned by a separate large enterprise. Students participate in the modules of project activities, form new and effective engineering solutions, to get skills of their practical implementation with regard to effectiveness, relevance and prospects of their further development. The production practice is very important in the preparation of bachelors and masters. To this end, the agreement on cooperation in the field of improvement of quality of preparation of students of SFedU concluded with the company RealLab (www.rlda.ru). It has allowed undergraduates to pass a work practice at the enterprise, custom-making thematic tasks of the enterprise on a contractual basis. Graduates of magistracy successfully find a job at the enterprise, providing thus strengthening of personnel structure. In this study, we propose a technique of teaching of bachelors and masters in "Control of technical systems". The main thesis is to use the technique of through projecting throughout the entire learning process. The trajectory of training is built for the student based on a module of project activity, training and production practices. The student studies the object, develops the control algorithm, programs it, chooses a set of technical means throughout the entire period of training with an exit to the protection of the final qualifying work

ENZYME ACTIVITY OF SEVERAL SOILS OF THE CRIMEA
DescriptionThe article considers the enzymatic activity and some other ecological and biological properties of zonal soils of the Crimea (cambisol, Chromic cambisol, different subtypes of chernozems). We have revealed significant differences in catalase, dehydrogenase, polyphenol oxidase, peroxidase, invertase for soils of the Crimea, which can not be explained only by the content of soil organic matter. Despite the low humus content of the soil, some have a high level of some enzymes. The level of enzyme activity depends on the reaction medium, the content of carbonate and other soil properties. We have also revealed that the agricultural use of brown soils under vineyards leads to a significant change in their properties and enzymatic activity

Description
In this article, on the basis of phenomenological consideration of kinetic processes in semiconductors volume, we have conducted an analysis, in order to estimate the drift and diffusion components of the output current for hot carriers in the total output of the conductivity structure of the chip. The result revealed amplitude and frequency characteristics of this component of the conductivity, illustrating a greater amount of its modulus and phase inversion near the field-strength values of Ghan effect. This can be used for designing oscillators of millimeter range of wavelengths. It is shown that the nonlinear diffusion component along with the drift is important for the output conductance of the test specimen

MANAGEMENT OF AN UNIVERSITY: EM-PLOYMENT AND PROFESSIONAL DEVELOP-MENT OF GRADUATES
DescriptionNeed of goals management by university on an indica-tor "employment" is proved. The problem definition is executed and ways of improvement of a control sys-tem by university and market policy are offered. Re-sults of the analysis of external impacts on an university as social and economic system, the maintenance of an exit of system, relationships of cause and effect of an exit and a system entrance are given
