The authors of this article have developed a questionnaire for pet owners and conducted a research on the nutrition and health of domestic dogs and cats in the urban environment. By results of researches, it is concluded that in the conditions of the city, cats are a preferable type of pets. The preferred type of food is mixed one, with using dry, natural and wet food. Food standards are followed by 46% of owners of 100% participants of the survey and only 43.3% from consulters with veterinary specialists in the field of feeding of a pet. Among non-communicable diseases, urological diseases are more common: urolithiasis, cystitis, endometritis and ovarian cyst
The article presents results of theoretical and experimental studies on the justification and experimental confirmation of the influence of hydraulic seeding process modes on the parameters of row seeding technology for seedling crops. It is hypothesized that it is possible to ensure a uniform depth of seeding within 0.5...1.5 mm by feeding seeds into the soil by hydraulic means using a liquid. We have compiled a nomogram of the influence of the height of the initial level of the liquid and its density on the amount of pressure exerted by it on the soil. It was found that the pressure of the polydisperse system on the soil increases with both the density of the liquid and the height of the initial liquid level. Experimental studies have been conducted to study the effect of the pressure exerted by the liquid on the soil and the speed of the drill on the depth of furrow formation and the depth of wetting the soil. The article determines empirical dependences of furrow depth on the pressure exerted on it for different types of soils. It is found that the depth of soil wetting decreases with increasing speed of the drill

To develop new promising soybean growth regulators, we have synthesized series of derivatives of nitrogen-containing heterocycles. Synthesized compounds have been studied as potential soybean growth regulators. Substances with a high growth stimulating effect have been found. The growth regulators affected the branching coefficient, the number of seeds in the beans and their weight. The yield increased by 6.7-23.4%, the quality of grain increased
The creation of high-quality grape varieties of domestic breeding is relevant in order to successfully import substitution. The purpose of these studies was to isolate and study the hybrid forms of the technical direction for the creation of promising high-quality grape varieties of domestic breeding, tolerant to phylloxera and with high quality wine-making products. The objects of research were the breeding forms of grapes of the technical direction, growing in on the hybrid section AZOSViW - a branch of the FSBSI NCFSCHVW. The studies were performed using modern and generally accepted programs and techniques. The selection of elite forms according to a complex of attributes based on many years of field and laboratory research is one of the main stages of the selection process. As a result of studying the potential of hybrid forms of grapes, the selection of AZOSViW of the technical direction highlighted the hybrid forms of grapes to the elite: III -59-21, III - 62-9, with good quality of final products and tolerance to phylloxera. The article presents a brief description of selected elite forms of grapes. The selected hybrid forms belong to the early-medium term of ripening, accumulate a high concentration of sugars and have an average cluster weight greater than that of the control variety called Krasnostop Anapa
The study was carried out with the financial support of the RHNF as part of the research project of the RHF RFBR 17-02-00475а "Application of metaheuristic algorithms for solving direct and inverse problems of optimizing the management of spatially distributed complexes"). The article discusses the use of artificial neural networks in frame expert systems, which in some cases make it possible to bypass a number of limitations of the standard version of frame expert systems. Several options for using neural networks in frame expert systems were considered and a number of tasks to be solved for each
The production of eggs is one of the most important indicators of the productivity of poultry, including chickens The main purpose of breeding chickens in the collections of genetic resources - conservation of genetic diversity. The chickens from the collection of genetic resources it is also possible to receive products, for example, in the form of eggs. The account of the egg productivity of the chickens showed that the intensity of egg production varies among representatives of different directions of productivity. The most stable egg-laying was possessed by chickens of breeds New Hampshire, Black Australian, Dutch white. These breeds are bred as breeds of egg direction of productivity. But they are characterized by long downturns in egg production, lasting more than 7 days. Chickens of meat direction by stable, but low intensity of egg production. All the chickens had a short period For all chickens a short period is characteristic, when the egg-laying is kept at a certain level. It is 30-40 days, after which there is a gradual decrease in this indicator. Such a high level of genetic diversity in egg production in gene pool makes it possible to use this bird as a model object for studying its features
The article discusses the results of the research on winter soft wheat which is connected with the studies of yield variability, depending on the year conditions and the variety, conducted in 2003-2014. The objects of the research were 34 varieties included in different years into the State register of breeding achievements and recommended for cultivation. The experiment was carried out by the predecessor of soybean on the medium background of soil fertility. The varieties were being cultivated both with the protection against fungal diseases and without it. The method of dispersive and variance analysis was used in mathematical processing of the yield data. The parameters of ecological plasticity (bi) and yield stability (S2) have been calculated according to the methodology of E.A. Eberhardt and U. A. Russell (1984). The range of variability has been defined according to V.A. Zykin (2000), the fulfillment of the yield potential has been set according to E. D. Nettevitch (2001). The research revealed that the new winter soft wheat varieties included into the State register of breeding achievements are mostly productive and adaptive. Their yield increases mainly due to the upper threshold. The new varieties differ in yield stability but we have not found out a certain pattern. In conclusion it must be mentioned that the implementation of Eberhardt and Russell model in analyzing yield data allows us to estimate general tendencies in its variation when the conditions of the environment change and to identify the most valuable genotypes. In order to rank genotypes according to the characteristics which are being studied we have to choose an agricultural background on which their maximum potential is realized
In modern conditions of quantitative and qualitative
degradation of science in general and economics in
particular, especially in our country, the scientific
direction of "Controlling" stands out not only for its
activity, but also the rapid intensive and extensive
growth. This work is the summary of the main
publications of scientific results on controlling
obtained at the Laboratory of economicmathematical
methods in controlling of Scientific
and Educational Center "Controlling and
management innovations" of Bauman Moscow State
Technical University. We discuss the concept of
"method", "tool", "mechanism", "algorithm" in
relation to the Controlling. Adequate use of these
terms is necessary for the formulation of sound
scientific results, and to provide their perception of
the scientific community. Innovations in the field of
management in industry and other sectors of the
economy based, in particular, on the use of new
adequate organizational and economic methods.
Controlling in this area - it is the development of
relevant management procedures used and the newly
established (implanted) organizational and economic
methods to the task. Development, systematization
and application of modern mathematical tools of
controlling are the main theme of our work. We
have considered the problems of controlling new
areas - controlling risks, quality controlling,
controlling organizational and economic support for
control tasks in the aerospace industry, controlling
research activities. We have also obtained new
scientific results in controlling personnel and

Human resources have recently reasonably gained more and more importance. Today, along with material, intellectual, informational and financial resources, they affect the efficiency of enterprises and organizations. Competent assessment of human resources, a clear understanding of means of interaction with staff and developing human potential are the basis for the effective work of both human resources departments and organizations as a whole. The complexity of assessing human resources necessitates the development of a toolkit, the use of which will simplify it and ensure that one receives the most accurate advice and assistance in making management decisions. A promising direction for the implementation of the designated toolkit may be the development of a decision support system, within which, among other things, the possibility of a multi-criteria analysis of alternatives will be available. Due to the fact that there are no methods for multi-criteria analysis of alternatives intended solely for assessing human resources, it is necessary to conduct a thorough analysis, the main purpose of which is to identify the most suitable basis for further adaptation and development. After conducting preliminary studies, the TOPSIS, MAUT, AHP and ELECTRE methods were chosen as the most promising for solving the problem
