Description
Efficient dairy cattle breeding are largely dependent from technology content and service animals. Most farms use a tethered way content. With this method of milking, the technology requires the introduction of new techniques to increase productivity on the farm and cost reduction of dairy products. The most rational is improving the design of existing milking machines. Regarded device for automatic removal of hanging part of a milking machine, its structure and working principle. The main unit of the device is a pneumatic motor that operates from the vacuum system of the milking plant. In the housing mounted on the shaft of the pneumatic motor rotor with curved vanes, there are magnetic elements. These elements should have the necessary geometrical and force parameters to ensure the normal operation of the device for automatic removal of hanging part of milking machine. The article describes a laboratory research and an analysis of the magnetic elements. In laboratory studies, we have revealed a dependence of the traction capacity of pneumatic motor from linear and power parameters of the magnetic elements, as well as established necessary geometric parameters and the magnetic field strength of the elements for normal operation

DECISION MAKING SUPPORT INFORMATION SYSTEM IN SPHERE OF SMALL AND MEDIUM BUSINESS COMPANIES SOLVENCY
DescriptionDestabilization of the economic situation in Russia at the end of 2014 and in early 2015 has influenced small and medium businesses (SMB) landing at first. One of the most important reason of high lending risks and, as a result, high lending rates is absence of reliable information systems for assessment of SMB enterprise default according to total analysis of their financial activities. Thus nowadays the reliable assessment of SMB enterprises solvency is the fundamental scientific problem, which one is highly actual for each credit organization because the bankruptcy of a credit institution is depended on it. At the same time high competition at the landing market leads to necessity of individual credit conditions existing, which takes into account borrower’s and lender’s benefits. In the present work the creating of reliable information and analytical systems for assessment of SMB company default method is suggested. This one is based on integration of probabilistic and statistical classification analysis methods (discriminant analysis, logistic regression, and classification trees), heuristic procedures (neural network) and interactive shell of the system using cloud technology. By the authors, there was solved the problem of small data amount, exception anomalous values and discrepancy normal distribution of sample by the generation of enterprises financial activity model database

DescriptionThe article is concerned with principal conditions, mechanisms and techniques on the development of teenagers’ subject qualities. Identification criteria of the development are described. Learning process is viewed as the main identification factor of teenagers’ status as subjects of learning activity. The conclusion is made about the influence of enabling educational environment and involvement of teenagers in learning group on teenagers’ subjectivity development. The definition of “enabling educational environment” is viewed as well. The article reveals the distinction between “educational environment” and “enabling educational environment”. The stage of teenager’s development as a subject of learning activity is identified by results of such personality activity dimensions as social activity, the attitude to school and learning process, the maturity level of learning activity and interests, self-concept, school progress. The articles points out the question of phased group development in the process of cooperative activity and communication based on parametric conception of small group development. The set of teaching techniques on personality activity dimensions is represented

ELECTROCHEMICAL THERMODYNAMICS OF CELLS IN THE CONDITIONS OF ELECTROMAGNETIC ENVIRONMENT
DescriptionThe article covers the basics of thermodynamics and the possibility of the application of its provisions to the basic biological entity - the cell under the influence of external electromagnetic fields. Thus, we consider a system whose properties do not change in time, if it does not occur on the external influences. If the system is subjected to such (mechanical, thermal, electrical, magnetic and other effects), then all its properties, or some of them are changing. If at least one property of the system changes, we will talk about changing the status of the system due to the fact that there was some process. From the point of view of external electromagnetic fields on the thermodynamic system - a cell of a living organism or plant is very important essence of the concept of work. Unlike conventional concepts of the work of expansion (pdV), which is not considered to be useful, we have introduced the concept of "useful" work dA /, which means the operation of the electric current, magnetic field or other physical fields in the design of various electrical devices and appliances used in livestock and crop. The impact of electromagnetic fields on biological objects also leads to a slight increase in temperature of the biological system and, as a consequence, it increases the rate of chemical and biochemical reactions and phase transitions, which is reflected in the increased activity of the biochemical processes in these objects. This, to some extent can explain numerous experimental results of scholars and practitioners concerned with stimulating crops, for example, during preplant treatments

LINGUISTIC AND CULTURAL FEATURES OF ACADEMIC TEXTS IN GERMAN AND FRENCH
10.00.00 Philological sciences
DescriptionA training text in a foreign language is a fundamental communicative unit of the learning process. However there is tracing a tendency to explain the text as a global fact in the scientific literature and to study language’s contacts with different sides of human activity, which are actualizing through the text. The data shows at first that linguistic and cultural features of training texts are connected with communicative directivity of the foreign language learning process, second, they are due to the goals and objectives of learning. In the article the cultural component of training texts is reviewed, the types of texts determining sociolinguistic behavior of the characters, with which someone learning foreign language should identify himself, are marked, sociocultural subject of texts of tutorials in German and French is analyzed. A pragmatic aspect of training texts is studied separately, quantitative and genre texts’ relations and authentic and quasi-realistic texts’ relations in German and French are compared. Studying of features of training text in foreign language allows characterize it as a universal unit, which fosters to form a communicative competence and influence the recipient complex. Results of the study expand knowledge about the methodical potential of a training text in learning a foreign language and culture and are of interest for experts in the fields of linguistic, linguodidactics and intercultural communication

CHALLENGES TO CONTROLLING IN THE MANAGEMENT OF THE HEAD OF THE CORPORATION
DescriptionManagement is considered as a service providing value creation in the corporation. Improving the quality of management and the formation of its competitive advantages is a priority. Controlling has a significant influence on the quality of management. However, for its implementation it is necessary to form the need to the head to establish a system of information - analytical management support. The survey of CEOs identified the lack of sustainable demand for controlling. The main source of the challenge for controlling is corporate executive. The reason of the lack of significant challenges to controlling lies in the existing system of management of corporations and, above all, in the person of the head. Formal and informal management as two complementary approaches, the components of the success of the head - the leader, the key characteristics of managerial behavior of the head and needs for intelligent management services were discussed in this article, a new concept of controlling as the management of intellectual service was offered

DescriptionRecently, the process of monetization of the evaluation of scientific activity was initiated, and there is a need for quantitative methods and comparable assessment of the effectiveness and quality of work of a scientist. There are numerous methods to reward for these results. What is common to all these techniques covered is the role of the Hirsch index or h-index. By itself, this index is well founded. However, in connection with the practice of application of h-index in our environment in the minds of the scientific community it has started some kind of mania, which the author proposes to call "Hirsch-mania". This mania is characterized by elevated unhealthy interest to the value of the Hirsch index, especially inadequate artificial exaggeration of this value, as well as a number of negative implications of this interest. In this article we have made an attempt to briefly describe some of the negative effects of this new mental infection that hit the public consciousness of the scientific community. And also we want to identify ways of overcoming at least some of their causes. This is the problem solved in this work. To solve the formulated problem, we propose to apply multi-criteria approach based on information theory, namely those options, which are implemented in an automated system-cognitive analysis (ASC-analysis) and its software tools - intelligent system called "Eidos

PERSPECTIVES OF DEVELOPMENT OF AGROLANDSCAPES IN THE STEPPE ZONE OF EDGE
DescriptionStudies of ecosystems allow estimation of difficult processes (physical, chemical and biological), taking place in them and determine how to manage them. At the heart of the natural systems there are freely interacting populations of different taxons, productivity of their above-ground structures, details of which are quite limited, and as underground systems, the data have even less information. In the late 60s and early 70s in the XX century a lot of information appeared associated with problems of environment, its pollution, lack of energy of food resources, clean water; it determined the root cause of the reaction of the population of developed countries on the aggravation of relations between society of people and habitat. Existed for a long time the concept of the exploitation of nature, which reflected on using soils, forests, water and other sources and which showed the power of mankind and its technical power over nature. In reality, this concept was just a common strategy of aphids sucking their environment. Understanding the real situation on the different levels of consciousness of the population defined situation of practical and scientific research in the field of ecology of different directions - chemical, biological, mathematical and other sciences. Development of ecology today will evolve to meet conservation and sustainable development of the biosphere, which experiencing constant anthropogenic pressure. An important problem of agrolandscape systems is an objective assessment of their productivity. Among the issues that determine the development of agricultural systems there are the natural conditions and soil fertility, crop dynamics over the years, the duration of the growing season of individual taxons, as well as the possibility of create of mixed crops, different type of life form, ecological features, physiological diversity of biochemical characteristics. Sowings this type allow, under certain conditions, obtaining stable yields under any climate dynamics and significant reduction of soil erosion. Combined sowing that is practiced in South East Asia, particularly in China, where the main components are the soybean and corn. The usefulness of mixed crops is the stability of yields over the years and the ability to emphasize their resistance to dry weather conditions

DescriptionThe key stage of clonal micropropagation, the micropropagation sensu stricto, affords to increase the propagation index for plants, especially perennials. In this study, we consider ways to optimize clonal micropropagation of remontant raspberry cultivars. It is found that microsprout regeneration rate is 78,5–96,0 % on the multiplication s. str. stage. The most multipurpose nutrient medium is selected with containing 0,5 mg/l both of BAP and GK. When one uses this medium, regeneration rate runs 79,0–94,0% depending on genotype with sprout high running 24,8–32,7 mm and sprout number – 1,2–2,2 per node. The optimal duration of growing cycle is 30 days with the propagation index within 6,6–7,8, depending of genotype
