01.00.00 Physical-mathematical sciences
DescriptionThis article describes a mathematical model of transport of salt ions in a cell with a rotating disk cation exchange membrane at transcendent current regimes, taking into account electroconvection. Based on this model, we had a theoretically study of the process of transfer of salt ions and the dependence of the thickness of the diffusion layer from the fall of potential. This article is a continuation of [8] and [9], it conducted a numerical analysis of boundary value problem for a system of equations Nernst-Planck-Poisson and Navier-Stokes equations, modeling the transport of salt ions in a cylindrical cell with a rotating disc cation exchange membrane based on electroconvection. It is shown there is an electroconvection vortex in the center of the membrane disc. The solution flows around this vortex and forms a stagnation zone in front of it. With the increase in the size of the fall of potential, the electroconvective vortex decreases and at some value, the electroconvective vortex disappears. The study was conducted in the 1000 s when the angular velocity of 30 turns in a minute and change of the potential difference of 0.2V to 1.4V with a step 0.1. As a result, in this study it is shown that the thickness of the diffusion layer is practically linearly dependent on the fall of potential. The linear dependence of the thickness of diffusion layer from the fall of potential, in the first approximation, is disturbed by a slight deflection curve, the causes of which are needed to be found by means of extra experiments

THE STUDY OF THE EFFECTS OF RICE QUALITY ON THE EFFICIENCY OF ITS PROCESSING
DescriptionThere were presented comparative analysis’ results of criteria rice quality used in Russian and international standards. Also there were shown summarized statistical analysis’ results of rice quality that was processed in 2013-2016 on rice mill plant at “Krasnodarzernoprodukt” Company. The purpose of research was to find factors that had influence on combining rice bulk effectiveness on specialized elevator. It was found that diapason of rice moisture content was quite small. Red rice content was ranging from 1.08 to 5.10 % with confidence interval of 1.98- 2.56 % that is evidence of small amounts of rice bulks with extreme high or low red rice content. Broken rice content varied in the wide range from 3.43 to 9.26 % with confidence interval from 5.84 to 7.26 % that shows necessity in length grading procedure applying for broken kernels removing at the elevator unit. Grain impurities content exceeded basic norm in 3-4 times that is a sign of low efficiency in the process of separation. During the treatment of rice bulks combined at the grain cleaning unit of rice plant broken rice cereals output varied in wide range from 3 to 9 % during single shift that is seems to be connected with kernels cracking increasing and rice moisture decreasing. Moreover, rice bran output also varied in a wide diapason from 10.2 to 17.0 % that could be explained by big swing in rice moisture, glassy texture and cracking of rice grains. According to our research it was investigated that current rice quality control system that is a base instrument of rice bulks forming for further processing is not quite efficient and as a result there should be created and implemented new methods and technical devices for quick and proper grain control that could assure stable technological regimes at different stages of rice treatment process and that would provide the best quality and the biggest output of rice cereals

Description
We have considered hybrid nontraditional and renewable sources of energy in terms of optimizing their work based on the knowledge of technical and functional peculiarities of each. We used classification of clusters of nontraditional and renewable energy of sources, depending on the proportion of replacing power in energy consumption and on the type of nontraditional and renewable energy of sources. We examined a simulation model of the hybrid cluster using the structural diagram and performed statement of the problem by means of the full and multifactor experiment. We applied the method of analysis of non-stationary random process disturbing influences

ROLE OF ALIMENTARY FIBERS IN TREATMENT AND PREVENTION OF THE OBESITY
06.00.00 Agricultural sciences
DescriptionExcess body weight is a serious problem, involving a set of diseases presently. For this reason, taking into account demands of science there was a development of production of food with the lowered energy value for the people having first of all obesity that led to production of substitutes. Even more often producers resort to use of nutritional supplements, which generally receive in synthetic way. In this article, we analyzed multiple references and summarized the material regarding beet fibers. As a result of numerous researches it has been proved that food fibers make favorable impact both on the separate systems of a human body, and on all organism. The use of the minor products of processing of the plant raw material is also critical; they allow improving the preventive properties of products and enriching them with dietary fibers, protein, and mineral elements and also development of food development of curative and preventive action. Citri-Fi food fibers which are received from dried-up orange pulp are well-known, they can keep a large amount of water throughout technological process. They exert positive impact on structure of fat that gives the chance to create a product with the lowered content of fat

DEVELOPMENT OF TURKISH JOURNALISM IN THE ERA OF THE TANZIMAT
DescriptionFor some of the Eastern countries - Turkey, Iran, China and Japan - XIX century passed under the sign of reform. Studying these countries today is important and relevant. Such an experience could be a tool for analyzing the reform aspirations of modern mankind, which is especially valuable for those situations which are determined by the trend of rapid economic and technological progress. Hence, there is a certain increase in interest of turkologists in recent years to study reforms in Turkey deeply, especially the period of the so-called "beneficent reforms" ( "Tanzimat-i hayriye"), which lasted for more than thirty years - from 1839 to 1876

CREATION METHODOLOGIES OF CONSUMER VALUE OF CONFECTIONERY
DescriptionIn the article the analysis of an entity of consumer value is provided, approaches to the description of a concept of value are discussed; problems of a research and measurement of consumer value are updated. The consumer value of goods expresses in a choice from a large number of similar goods, conditions for which can be its cost, qualitative characteristics, gradations, the sizes. It is set that in case of determination of consumer value it is impossible to be guided only by its cost, here its qualitative characteristics, conditions of the supplier and the level of service will be an important index for acquisition by wholesalers. The consumer value of production proceeds from the advantages got by the buyer from his acquisition and costs of its purchase made by it. In addition, to understand priorities of the buyer, it is necessary to select analysis stages of consumer value, which are divided into several processes; they include production, a market research, and questions of sale and support of production. Authors consider the value as one-dimensional and multivariate construction, select three basic approaches to value assessment. It is set that pricing based on prime cost is made from analytics of need of the buyer, with establishment of necessity of goods for it, and its cost should characterize its advantages

10.00.00 Philological sciences
DescriptionThe article deals with the investigation of different naming constructions of characters in the novel, which indicates emotiveness in communicative acts. In due course of the analysis the concept of “social fields” has been introduced in order to reveal the means of emotional expression. The naming of the individual with different anthroponym forms (a name, a surname, nickname, etc.), introducing the concept of social field (SF), made it necessary to use such concepts as “norm/not norm” in the analysis of function proper names. Because of breaching the norms of naming proper names take emotional coloration. Such emotionality may be positive or negative. It depends on many factors: a situation of communication, social field the communicators belong to, their view of life, etc. The emphasis of the norm and not norm of naming in every social field helps us to identify the character of emotions and disclose the relationships of characters to the anthroponym by means of naming. Any not norm of naming is the change of character’s relationships to the anthroponym

Description
Currently, it is important to have a solution for problems related to the prevention of potential accidents and the minimization of technological risks, particularly in the oil and gas industry, the number of accidents in which remains at a high level. Causes of incidents and accidents at hazardous production facilities are often non-compliance with required technological parameters, insufficient equipment of the technological systems with safety devices and automated control systems of processes. The article presents a comparative analysis of the methods that can be used in identification of hazards at different stages of the life cycle of the technological object: location, design, commissioning, operation, reconstruction. In order to develop security measures for the selected plant, we have used a method of analysis hazard and operability (HAZOP). The object of the study was projected technological installation for obtaining of bitumen with 24 thousand tons per year performance on raw material. For the working group of experts we have step-described the order of research dangers of specific nodes of the process plant, including determining the adequacy of the protective measures provided by the project and the development of recommendations on elimination of the revealed deviations and to reduce the effects of their manifestation. The most harmful deviations of process parameters during operation of the installation were found. We have proposed hazard criteria of operation, taking into account the probability and severity of deviations of technological parameters. We have also confirmed that the HAZOP method allows not only to identify the causes of hazards and consequences of their implementation but also to develop recommendations for their elimination

THE GENESIS OF THE "LEARNED IGNORANCE" DOCTRINE AND IT'S COGNITIVE VALUE
DescriptionA clarification and interpretation of the philosophical meaning of the "learned ignorance" doctrine, viewed from an aspect of a history of philosophy, involves a necessity to educe a genetic and essential relationship between the "learned ignorance" principle and the apophatic tradition of thought. The article describes the genesis of the "docta ignorantia" principle: it appeared in a context of theology as a method for attaining of the knowledge of God. It is this concept that often forces researchers to restrict the epistemic potential of the "learned ignorance" principle, leaving it in limits of negative theology and mystics. However after investigating the difference between the philosophical and the religious understanding of theology the authors of the article interpret the paradigm of the "learned ignorance" to be a fundamental philosophic principle of thought and cognition. Nowadays it is widely accepted, that the paradigm of the "learned ignorance" in it's classical form originates from the apophatic tradition. The article points out, that the representative examples of apophaticism, which could be found in the christian theology, on the one hand, were based on a solid philosophic tradition (predominantly platonic and neoplatonic), and on the other hand, did not complete a spread in a world philosophic thought of a definite (apophatic) tradition, which had an intimate connection with the paradigm of the "learned ignorance", postulating as it's main intention a seemingly paradoxical comprehension of the Absolute, supposed to be absolutely incomprehensible. The results of the scientific research in a field, thus defined, are presented briefly in this article
