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

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

PRECEDENT TEXTS AT LESSONS OF RUSSIAN AS A FOREIGN LANGUAGE
DescriptionThe relevance of the article is caused by the necessity to form the linguacultural competence of foreign students studying Russian language that corresponds to the Contemporary didactics of foreign language teaching. The case (precedent) texts are considered as one of the main means of linguacultural orientation used in practices of teaching Russian as a foreign language. The necessity to study the case (precedent) texts in this way is defined by its active use in language and by the presence of cultural component determining the valuable priorities of Russian vision of the world. Therefore, the assimilation of case (precedent) texts as actively used language elements of Russian culture is the most important principle of developing the communicative competence. The aim of this work is the attempt to describe the case (precedent) texts, acting as key material in the practice of teaching Russian as a foreign language. The article reveals the specificity of case (precedent) texts in the context of national culture, it also identifies and analyses their formal and semantic features, the peculiarities of perception of the case (precedent) texts by foreign students. The researching results of the peculiarities of the case texts that are used in the process of studying and teaching Russian as a foreign language, allow drawing the conclusion that the efficiency of assimilation of the considered units is caused by knowledge of their structure and semantics, by understanding the values, determined by them

BEST AVAILABLE TECHNOLOGY AS AN ELEMENT OF ECOLOGICAL MODERNIZATION OF PIG-BREEDING
06.00.00 Agricultural sciences
DescriptionThe article analyzes the main factors of the negative impact of pig farms on the environment, for the characteristics of which are used criteria such as emissions of ammonia, methane, nitrous oxide, dust, loss of nitrogen and phosphorus in manure output, feed consumption and water consumption, economic evaluation, capital costs of reducing emissions, operational cost. The technical level, resource and energy consumption in the production of pork have been analyzed in a comparative perspective. The necessity of implementation of best available techniques in order to ensure environmentally oriented production growth has been provided. The importance of the development of technology selection algorithm and clarification the basic criteria for the selection has been emphasized. Also, there was detected the role of technical regulation for the prevention of excess pollution. The necessity of a comprehensive approach was proven for the implementation of NDT in the framework of environmental and industrial policies. Implementing NDT will provide the ecological modernization of pig production, which is confirmed by the experience of European countries, successfully implementing the concept of NDT from the 70s of the twentieth century. At the same time, not only economic measures should be used (exemption from pollution charges, grants and subsidies), but also the administrative tools (based on a valuation of NDT, integrated permits). Daylight technological regulation will provide "green" economic growth and will contribute to solving social and economic problems. Implementation of the project is not possible without the exchange of information, the definition of time and economic characteristics of the implementation of NDT, comparative analysis and classification technologies to NDT. In 2017, it has already been planned to publish the NDT reference "Intensive breeding of pigs,” while the implementation of best available technologies will become the basis of ecological modernization of the industry. The inclusion of the author to the technical working group on development of the handbook "Intensive breeding of pigs" allows to participate on-line in the discussion of topical issues

Description
In the article we present the results of comparative researches of herbaceous covering of plant communities in the alpine zone of the Republic of Dagestan on the example of Dido- depression. The plant covering of the investigated region differs in extraordinary variety. The general regularity of plant distribution is vertical zones. There were made 6 ground profiles at different elevations from 1450m to the alpine zone at 2500m above sea level. Variety of phytocenoses is connected as with changes of ground conditions, so with environmental conditions. We have researched and identified the types of grounds with laying of grounds profiles on the vertical zonality. There we studied the specific composition of herbaceous plants on the examined ground and given names to plant communities. The studying phytocenosis are analyzed by productivity of functional groups. We have shown the share of each species and their abundance. Of all plant communities, the mass of herb differ dominates. The composition of plant communities is analyzed, depending on high-altitude grades and degree of anthropogenic load influence

ASSESSMENT OF COST EFFICIENCY OF USE OF DEVICES OF ULTRASONIC HANDLING OF FUEL
DescriptionOne of important features of development of modern society is special attention world the public to problems of rationality and efficiency of use of the existing energy resources, universal implementation of technologies of energy saving and search of renewable energy resources. Gradual depletion of world reserves of oil, increase in prices for traditional motor fuels, adverse ecological situation and other factors prove the relevance of more urgent use of the available resources and works promoting development of this direction. Deterioration in a global ecological environment requires adoption of more strict requirements imposed to the fuel used in an agro-industrial complex. According to the principle of cost accounting, each entity can rely only upon itself and consume only the resources it has. It is known that fuel costs constitute a considerable part in an expense structure of agricultural enterprises. In this case, the reduction in fuel consumption can be achieved through improved processes of fuel mixing and fuel processing (fuel dearomatization, ultrasonic treatment, magnetic, electrostatic and electromagnetic processing). Bench tests of a diesel engine equipped with an experimental device for ultrasonic treatment, showed good results, confirming the relevance of the use of such devices. Devices for processing are compact enough and consume little energy, while having a sufficiently high coefficient of performance. Having small size and relative simplicity of design that does not cause complex technical issues in production, these devices can be used on virtually any type of equipment that is used for the solution of agricultural problems. The purpose of this article is to evaluate the economy of the diesel fuel when ultrasonic treatment on the example of the motor transportation enterprise
