abstract 1471903018 issue 147 pp. 150 – 159 29.03.2019 ru 419
Issues related to the contamination of crops are topical and very relevant. All this fully applies to the main crop produced in the South of Russia – winter wheat. In this regard, the presented results of studies of the influence of predecessors and tillage technologies on the development of weeds in the cultivation of winter wheat are relevant. Experimental studies were carried out in conditions of many years of experience located in the FEDERAL state scientific institution «ANTS «Donskoy». The influence of different methods of sowing (ordinary, scattered, belt) and technologies of tillage (dumping, non-dumping, surface, small) on infestation of winter wheat is considered. It is established that the least amount of weed plants is provided at scattered sowing on the background of deep tillage. The main treatment at a depth of 18-20 cm reduces the number of weeds by 47% in comparison with the surface (8-10 cm), and the scattered sowing reduces their number by 80%, since weeds are in more severe conditions compared to winter wheat, the rapid development of which contributes to the optimal nutrition area. Of the predecessors, the most acceptable is the steam with the number of weeds 7-25 PCs / m2, which is several times less than after peas, or corn after silage

The article contains analysis of consumption of the main natural resources and their use in the automotive industry. It is noted that during the manufacture of the car pollution is obtained in 2 times more than in exploitation. It defines the essence of recycling process (autorecycling) and its ecological components. Activity on autorecycling was expressed through the index of recycling efficiency. We have analyzed the global car fleet and average annual amount of automotive waste, million tons per year. We point out that one of the economic components of recycling is the use of parts and mechanisms of machines ready for further use, by qualitative technical diagnostics with use of diagnostics devices. The problem of utilization technological effectiveness of cars as set of the properties characterizing fitness of a design to utilization at the minimum costs of time, work, means, providing the minimum negative impact on environment and the maximum involvement of components of the written-off equipment in processing or a reuse is considered. The main definitions and factors defining utilization technological effectiveness and its main indicators are given. The main ways of increasing of utilization technological effectiveness of cars are offered and the conclusion is drawn that simplifying dismantling of the car on automobile components, reducing dismantle time, time of draining of everything, the liquids and oils applied at operation, applying environmentally friendly materials, etc., the designer can increase technological effectiveness of the car at utilization. As a result of the solved task we have got ecological and economic effect of vehicle recycling

THE FEATURES OF A COSTS CLASSIFICATION FOR THE ACCOUNTING POLICIES FORMATION FOR MANAGEMENT PURPOSES

abstract 1191605034 issue 119 pp. 477 – 487 31.05.2016 ru 420
The formation of accounting policies for internal management purposes plays an important role in the modern world. It allows choosing the most suitable way of calculation of the cost, to ensure control of the movement of resources and optimize costs. The aim of the research is to develop a cost accounting section and a fragment of the organizational and technical accounting policies section for internal management purposes. In the course of the research we have been justified by the basic elements of organizational and technical section of accounting policy. The introduction of elements presented in this work can improve the effectiveness of management accounting system functioning through the distribution of duties and responsibilities for its organization and management. The authors propose a reflection of the listing of the automation software used cost accounting software with the options that reveals the technical section of the organization of management accounting system. The developed classification of the main types of regulatory documents (legal and reference documents, the provisions on sections accounting or managerial tasks, instructions for the regulation of individual transactions in management accounting) and the way of reflection in order on approval of accounting policy of the organization contribute to building an optimal document system within the economic entity. In order to reduce the time to build a classification of costs in the article it is recommended to synchronize the expenses from the article directory in accounting. This will optimize the work of management accounting system and establish a link with this system accounting. Using the developed coding system will lead to greater analytic, completeness and transparency of management accounting. Thus, we have substantiated and disclosed the practical and the theoretical significance of the introduction of the cost accounting system developed in the activities of economic entities

abstract 1221608044 issue 122 pp. 642 – 655 31.10.2016 ru 420
The article is devoted to solving the urgent task, which is improving the accuracy of transient simulation modes of power supply systems of sugar factories. The material of the article is exploratory in nature, manifested in the fact that we have studied various mathematical models designed for the analysis of symmetric modes of deep bar induction motors. A number of the provisions of article have scientific novelty, which lies in the approach to the choice of the coordinate system for modeling deep bar induction motors. We have formulated the requirements for transient analysis method for deep bar induction motor. We have developed the mathematical models of high-voltage induction motors in different coordinate systems for the analysis of steady-state and transient modes of operation. Based on double-circuit rotor model of induction motor, an analytical expression for the frequency characteristic of the deep bar induction motor is obtained. As an example, we have calculated and presented real and imaginary parts of the frequency characteristic of the induction motor type 2АЗМ-2000 with slip s = 1. The mathematical models of induction motors allow using mathematical apparatus more efficiently to explore different symmetrical modes of engines. The study proposed to use transients in the power supply systems of sugar factories for the analysis. The authors suggest an approach to modeling, which can also be useful for modeling induction generators

MODERN ASSESSMENT OF NUTRITIONAL VALUE OF SORGHUM FORAGE

abstract 1231609052 issue 123 pp. 783 – 792 30.11.2016 ru 420
Sorghum is a source of concentrated, succulent and coarse forage. Its grain is used for making the mixed fodder and as the concentrated forage for swine, cows, sheep, horses and poultry. Sweet sorghum is successfully used for silage and haylage. Green chop of Sudan grass is used as fresh food for domestic animals and it’s used for making hay and silage. The nutritional value of the fodder is the way to meet the animal needs in nutrients, necessary for living. To determine the nutritional value of the fodder, oat fodder units and energy fodder units or exchange energy are used. At present the assessment of nutritional value according to fodder units is being revised, because it doesn’t give the true picture of the value of fodder nutrition and animal needs in nutrients. The general energetic nutritional value of fodder is considered as contents of all organic substances, supplied with fodder or with its energy. The nutritional value of fodder is valued according to the characteristics of its chemical composition, digestion of nutrients and general (energetic) nutritional value. The purpose of the work is to assess the nutritional value of fodder, obtained from the best sorghum varieties, as the food for different kinds of agricultural animals. Sorghum, used as fodder for poultry possesses the largest nutritional value. Among the grain sorghum varieties, the variety ‘Zernogradskoe 88’ has got the biggest value of fodder units. The green chop of Sudan grass and green fodder for silage of sweet sorghum possess the greatest nutritional value for swine. The varieties of Sudan grass ‘Krasava’ and ‘Arkadiya’ and the variety of sweet sorghum ‘Listvenit’ are the best varieties according to the contents of fodder units

SIMULATION OF A PLASMA CHANNEL AND TRACK IN MOTION OF PLASMA SOURCE IN CONDUCTIVE ENVIRONMENT

abstract 1321708129 issue 132 pp. 1492 – 1516 31.10.2017 ru 420
A model is developed that describes the formation of the plasma channel and the trace when moving in a conducting medium of various objects that are sources of plasma - ball lightning, plasmoids, charged particles, and so on. To describe the contribution of conduction currents, we modified the standard electrostatic equation considering the vortex component of the electric field. As a result of this generalization, a system of parabolictype nonlinear equations is formulated that describes the formation of the plasma channel and the track behind the moving object. In this formulation, the problem of the formation of the lightning channel in weak electric fields, characteristic for atmospheric discharges of cloudearth, is solved. Numerical simulation of the motion of plasma sources in a region with a ratio of the sizes 1/100, 1/200 makes it possible to find the shape of the channel and the total length of the track, as well as the branching regimes. It was previously established that there are three streamer branching mechanisms. The first mechanism is associated with the instability of the front, which leads to the separation of the head of the streamer into two parts. The second mechanism is related to the instability of the streamer in the base region, which leads to the branching of the streamer with the formation of a large number of lateral streamers closing the main channel of the streamer to the cathode. The third branching mechanism, observed in experiments, is associated with the closure of the space charge to the anode through the streamer system. These branching mechanisms are also revealed when the leader is spread. Numerical experiments have revealed a new channel branching mechanism and a trace behind a moving plasma object, caused by the conductivity of the medium

FACTORS OF THE WORLD ECONOMY DEVELOPMENT REFERENCES

abstract 1181604068 issue 118 pp. 1097 – 1108 29.04.2016 ru 421
The article is devoted the analysis of factors of development of world economy. These factors were considered in the dynamics and historical perspective of the development of world economic relations on the example of the world's leading economies. In the current economic crisis, many social problems that require action at the international level have exacerbated. Currently, however, a constructive dialogue between the States has been suspended. Built for many decades of diplomatic, cultural and partnership relations are in the stage of deep depression and decline. This phenomenon is accompanied by strong sanctions policy both on the part of the EU and the Russian Federation. Review of data for the analysis of world economy development factors has shown that globalization and integration processes at the present stage do not have positive dynamics. For the validity of the findings and an adequate assessment of the existing macroeconomic situation the most comprehensive and comparable information was considered. We evaluated the factors having the main impact on the dynamics of global economic processes development. Thus, the analysis of world economy development factors has shown the necessity of overcoming of contradictions between the leading countries to overcome the global challenges that no nation can solve alone. This requires a civilized dialogue of world economic and political leaders

ESSENTIALLY-LINGUISTIC PARADIGM’S INFLUENCE TO TERMINOLOGICAL FIELD OF ACCOUNTING DISCIPLINES

abstract 1191605044 issue 119 pp. 606 – 626 31.05.2016 ru 421
Market transformations have been continuing for more than twenty years in our country, and categories of accounting disciplines are still not structured. This leads to difficulties in unified understanding of most important indicators. These issues are devoted to research in the sphere of essentially-linguistic paradigm, that reflects relationship of linguistics and accounting. Essentially-linguistic paradigm works with the titles of concepts and their essential content. In this article, some categories of financial and management accounting illustrate the basic provisions of the paradigm. Attention is paid to such concepts as depreciation and amortization (financial accounting), management accounting and controlling (accounting systems, formed for making management decisions). There is a profit margin generated in the accrual method (financial accounting system) and cash basis (management accounting system) within the framework of practical implementation of essentiallylinguistic paradigm. Accounts’ correspondences are described for reflection of these indicators in accounts. Marginal income reflects using double entry; contribution reflects using of off-balance accounts. There are conclusion about the crucial role of essentially-linguistic paradigm in the process of decisionmaking

SYNTHESIS OF A SYSTEM OF OPTIMIZATION OF CONSUMPTION OF NONRENEWABLE RESOURCES

abstract 1221608063 issue 122 pp. 919 – 928 31.10.2016 ru 421
The NP-problem of discrete optimization of consumption of non-renewed resources is considered. The weights of edges of the graph of resources set cost of consumed resources. It is offered to use the transitions of discrete system conditions on the complete graph with number of vertexes, equal to quantity of discrete resources, for the problem decision. The purpose of such system is construction of a chain of the predetermined length and the minimum weight on the complete graph. The problem factor is factorial growth of number of variants of chains on graph at linear growth of quantity of resources. The main idea consists in a use of found statistical regularities of transition ranks of discrete system at construction of chains with the minimum weight on graphs of the any size. Use of ranks allows to abstract from concrete weights of transitions and to find the property inherent optimum. In this article, the structure of discrete system is presented and its functioning in a mode of analysis of ranged decisions is described. Distinctive feature of the presented system is use of the generator of ranks, the generator ranged chains and the statistics block. They are used for definition of distribution of suboptimum decisions. In addition, the article contains the description of structure and functioning of discrete system in a mode of synthesis of suboptimum decisions on the basis of the found distribution of probabilities of local decisions. Novelty of the offered approach to construction of solvers of NP-problems is in using empirical functions from ranks of local decisions to control the search
