ELECTROCHEMICAL THERMODYNAMICS OF CELLS IN THE CONDITIONS OF ELECTROMAGNETIC ENVIRONMENT
Description
The 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

ECONOMIC SECURITY OF A COMPANY: NATURE AND FACTORS
Description
This article is dedicated to the modern problems of economic security of organizations. The subject of research is economic security of a company that is actually a question of the economic science and practice in the changing realities of the activities. The author researches questions of determination of economic security of enterprises by modern Russian scientists which are reduced to three different treatments of the nature of this economic category. The first approach defines economic security based on the availability of threats. The second approach is expressed through the provision of economic security as a condition. The third approach is a symbiosis of the first two. Factors classifications are provided coming from different factorial signs which can be based on the analysis of their display area, effects and as resources of the enterprise. Classification on the basis of the resource approach seems original that allows identifying areas of risk exposure and elements of the economic security of the enterprise. The authors have noted that resources can be personnel, technology, organizational structure, innovation, management, property company; finance companies, etc. All the factors can be divided into qualitative and quantitative which influence to economic security enterprises alike. The potential of resource approach is not disclosed and this is actually a problem of modern economic science

Description
The 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

Recently, 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

Description
The article is devoted to the creation and activity of principally new organs of local self-government for Russian state – province and uyezd Zemstvos, which were formed by means of elections. Peculiarities of political and legal mechanism of formation of overall class organs of local authorities having too many powers in decision of questions of local sense are disclosed. Attention is paid to incompleteness of legislative regulation of many electoral procedures that made the sphere of administrative discretion significant. There were enlightened principally important characteristics of elections in Zemstvo which are overall class and combination of a principle of property qualification with noble family class representation, on the basis of which the author makes the conclusion on necessity of extension of representations of modern legal science on present qualifications. The comparative analysis of public polemic on the questions of results of Zemstvo reforms is conducted. In general bulk of ideas on extension of Zemstvo representative law the author was singled out two main trends: extension of quantity of voters by means of decrease of qualification limitations and equalization of representation of different social and class groups of population. On the basis of analysis of legal bases of formation and development of electoral process in XIX century the assessment of adequacy of modern system of Russian representative legislation is implemented

Metric describing the accelerated and rotating reference system in general relativity in the case of an arbitrary dependence of acceleration and angular velocity on time has been proposed. It is established that the curvature tensor in such metrics is zero, which corresponds to movement in the flat spaces. It is shown that the motion of test bodies in the metric accelerated and rotating reference system in general relativity is similarly to the classical motion in non-inertial reference frame. Maxwell's equations and Yang-Mills theory are converted to the moving axes in metric describes the acceleration and rotating reference frame in the general relativity in the case of an arbitrary dependence of acceleration and angular velocity of the system from time. The article discusses the known effects associated with acceleration and (or) the rotation of the reference frame - the Sagnac effect, the effect of the Stewart-Tolman and other similar effects. The numerical model of wave propagation in non-inertial reference frames in the case when potential depending of one, two and three spatial dimensions has been developed. It has been shown in numerical experiment that the acceleration of the reference system leads to retardation effects, as well as to a violation of the symmetry of the wave front, indicating that there is local change of wave speed

Description
With the transition to bachelors training, there was a question about the structure, content and scope of final qualifying works (FQW), performed by graduates upon completion of learning in high school. However, given the specificity of the different learning for specialist and bachelor, the time available to perform educational plans of the graduation project for specialist and FQW for bachelor and a number of other factors, the simple transfer of the requirements for the implementation of the graduation project specialist at the requirements for the implementation of FQW for bachelor seems unacceptable. Despite the existing experience of preparing and defending FQW for bachelors-builders in various universities of the country, scope of work, their structure and the number are not uniquely determined. Different approaches to the implementation of FQW for bachelors are observed even in different manufacturing departments of the same faculty. For the most successful implementation of FQW by students studying in the direction 270800.62 «Construction», training profile «Industrial and civil construction», as graduating department for which acts the KubSAU department of building production, we have developed requirements for the FQW structure. The totality of these requirements is a definite system in which students independently, in consultation with the supervisor, choose one of the structure options of performed FQW. Basic principles of the structure of the FQW, and the requirements for its scope and content are listed in this article

Protective forest plantations, shelter belts and plantings along the highways of Central - Black Earth region and southern Russia are badly damaged, and in some areas destroyed. Therefore, they can not perform their functions and require major reconstruction or restoration. The most resistant and applicable trees and shrubs to create protective forest plantings are: maple, ash, elm species and three-thorned acacia, honey-locust, white and yellow acacia, and other legumes breeds with high drought tolerance, disease resistance, technogenic pollution and pest damage. For the creation and restoration of protective forest plantations we require seeds of these species containing pericarp. In Voronezh State Forestry Academy we have carried out a scientific research for creation of a machine for extracting seeds from the legumes. Analysis of the results of scientific research of prototyping machines showed that they were made without considered technological and mechanical properties of the legumes theoretical researches workflow machines for extracting seeds from the legumes and scientific basis of design parameters and operating modes. In this article we have a presentation of the experimental sample of the machine for extracting seeds from the legumes and theoretical investigation of the workflow in the batch hopper. According to the results of the study, we have obtained a mathematical expression, which allows you to define the parameters and modes of operation of a brush-grater device
