01.00.00 Physical-mathematical sciences
DescriptionThe article continues the cycle of their studies associated with the formulation and development of methods of construction of nonnegative solutions of inverse problems for dynamic systems. In this article the authors formulated and investigated inverse problems for dynamic systems: model of Samuelsson– Hicks. The technique of constructing non-negative solutions of the studied inverse problems. This method is based on the following scheme of the solution. First, we have to identify the formulation of the direct problem, then the formulation of the inverse. This work investigates how correct the mathematical models describing the dynamic economic system are. Further, in the specified tabular solutions of the direct problem, we have built a system of algebraic equations containing the unknown estimated parameters of the studied model. Then posed inverse problem is reduced to solution of a problem of quadratic programming, the solutions of which are defined in MS Excel. The theoretical material is accompanied by the specific example

Description
Long-term storage of fruits can be achieved by means of their special preparation by pre-treatment before storage by electromagnetic fields of extremely low frequency (ELF EMF). In the current study patterns of influence of ELF EMF pre-treatment of fruits on the effectiveness of reducing microbial contamination during storage for the development of effective technological modes of preparation of fruits before storage are revealed. Qualitative and quantitative characteristics of microbial contamination of the fruits’ surface were studied. Effective modes of fruits (apples and pears) treatment by ELF EMF were established - for apples: frequency - 22 Hz, current - 10 A for 40 minutes, and for pears: frequency - 26 Hz, current - 5 A for 50 minutes, allowing to reduce to the maximum extent the microbial contamination of their surface, and also to reduce the loss of their weight from microbial spoilage during storage. The terms of storage of processed by ELF EMF fruits under refrigeration were established - for apple varieties Idared and Golden Delicious - within 8 months, for pear variety Conference - for 7 months

REGRESSIVE METHODS OF PROGNOSTICATION OF THE LOAD-GRAPH OF ELECTRICAL EQUIPMENT
DescriptionThe article discusses the use of regression methods of forecasting the deterministic time series on the example of the load curve. Forecasts of the load curve of electrical equipment are the demands of consumers and their security in EPS. All predictive tasks are based on prediction models. Electricity consumption is happening on an electronic level; storing electricity on an industrial scale is impossible, the consumption depends on many random factors. Therefore, generally, we use a combination of mathematical and heuristic models. This is the daily task of power systems and many technical, economic and commercial decisions on the management regimes depend on its solutions. Development of methods of forecasting of the energy consumption in the system of decision-making today is one of the priority directions in the Russian power industry. Therefore, the work associated with the development of methods and algorithms of forecasting of power consumption in the power sector is still relevant

THE METHOD OF THE DRYING GRAIN INTENSIFICATION WITH ACTIVE VENTILATION USING MICROWAVERECYCLING
06.00.00 Agricultural sciences
DescriptionThe need of improving the grain drying technology is due to a significant volume of this operation, high specific energy and high standards to preserve quality of grain. In this regard, the development of new technologies and equipment aimed at reducing the cost of fuel and electricity, providing the preservation of grain quality has essential meaning to reduce the drying cost. Usually, the electrophysical effects on the dehydrated material not only contribute to the thickness reduction or destruction of the boundary layers and increase the surface of phase contact, i.e. they cause the combined effects of the intensification of the drying process that is economically favorable and they say for a broader practical use of electrotechnologies. Method of grain drying using microwave recycling in installations of active aeration bunker type allows increasing productivity compared with standard technology for up to 30% and reducing process energy consumption by 17%

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

PRODUCTION ECOLOGICAL CONTROL OF IMPURITY GROUNDWATER IN WELLS OIL REFINERY TUAPSE
DescriptionProduction ecological control is an integral part of the national environmental monitoring system. The article describes the results of production ecological control of impurity of groundwater drawn from wells in the territory of the Tuapse refinery and presents a situational plan of wells layout in the Tuapse refinery. Analysis of groundwater was represented from 2012 to 2016 with their content (mg/l) of oil, phenols, plumbum, chloride, and anionic surfactants. We have revealed the excess of oil products and phenols and developed measures to reduce concentrations of these substances in the groundwater refinery in Tuapse

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

USING A FOREIGN LANGUAGE VOCABULARY IN THE LANGUAGE OF THE MEDIA
10.00.00 Philological sciences
DescriptionThe authors of this article affect the actual topic of the use of foreign words in the media, which is inevitable in our time due to changes in the state system and economic structure system of Russia. Number of foreign words in modern Russian language is very large and is growing every day because almost every English word can be borrowed regardless of the appropriateness of such replenishment of lexical structure. The causes of borrowed words can be different in nature factors, the need for new forms of language, in a variety of means, brevity and clarity, in convenience. The reasons for borrowing in the language of the mass media, is seen terminology "craze" expressive originality, emotional expression and the identification of sublanguage. The process of borrowing the words does not occur spontaneously and at the same time. It happens for a long time, gradually, provides a series of steps and stages. Russian language recently borrowed a large flow of English words with suffix -ing-, clear structural separability and value received and the foreign language element -maker, quite confidently took its positions in the language prefix -super

EXISTENTIAL PROBLEM OF FEAR IN THE М.Yu. LERMONTOV'S WORKS AS SOCIOCULTURAL CONCEPT
DescriptionThe article explores the notion of fear as an existential concept in M. Yu. Lermontov’s literary oeuvre. In many of the poet’s works, the characters, finding themselves in difficult limit situations, experience a wide range of emotions which Lermontov describe in detail using self-reflective approach. In analyzing the theme of fear featuring in Lermontov’s works as a socio-cultural concept, the author of the auricle describes each emotional state separately: fear of loneliness, fear of betrayal, a whole range of various strong emotions emerging in relation to fright and to the experience of horror. But the governing emotion in existential fear is a fear of Nothingness as an inevitable fate of every finite human self. The article describes a variety of ways to overcome fear and complex internal conflicts offered by Lermontov

ISOMORPHISM OF SYSTEM STAGES OF EVOLUTION
DescriptionThe article discusses and explains the similarity of organizational, structural and functional «solutions» at different system stages of the evolutionary development presented in nature and society. It is shown that at any level of biological organisation transition to a new stages of evolutionary development is implemented not only via «classical» individual changes (adaptations) of the particular organisms, but also by means of: 1) integration of organisms into the new systems of «superorganisms», 2) the differentiation of their functions or the division of labor, and 3) the development of internal and external communication, integrated into the overall communication system, ranging from single cells to ecological and social communication. The article argues that the distinctive characteristic of the present stage of evolution is cumulative cultural evolution of complex social systems that support (scaffold) the development of their individuals, through learning processes. It is shown that such social systems still have structural and functional isomorphism with biological systems; however, their reproduction and transmission implemented predominantly through more developed in the human community non-genetic inheritance systems, the advanced division of labour and distributed cognition.
