PROSPECTS OF RECEIVING AND USING LIGHT WATER
DescriptionIt has long been known that mountain glacier water has special properties. It was found that such water contains fewer molecules with the heavy isotope of hydrogen - deuterium. On Earth, there are constant evaporation-condensation processes. The resulting protium water falls as rain. It is noted that the body of animals, as well as tropical fruits and vegetables containing water with an isotopic composition close to the composition of rainwater into these areas. When the nuclear industry began to produce heavy water, a byproduct of the production was the light water, which had a lower content of deuterium. Over a lifetime, a person drinks about 80 tons of water. As a result, the body receives 12-16 g deuterium and associated oxygen isotope 18O. This leads to damage to the genes, premature aging and the development of cancer. Numerous studies have identified a positive impact of light water on the growth of plants and living organisms. The biological effects of light water include the ability to optimize the biological reaction rate, the stimulation of cell division, radioprotective properties and antimutagenic effect. In Russia and abroad patented several methods and devices for producing light water, with severe medical and cosmetic properties. This water has become popular among the population. It has a higher value in comparison with typical drinking water. The article describes one of such units. In order to achieve its goals there occurs treatment of drinking water and low electromagnetic field is extremely low frequency. This plant is used to produce food protium water in the laboratory. It allows you to clean tap water from the deuterium content of tritium, salts and contaminants

A NEW MATHEMATICAL MODEL FOR OPTIMIZING FRACTURE LENGTH IN THE IRANIAN OIL SAND RESERVOIR
DescriptionCreation of hydraulic fracturing in the physical structure of the reservoir rock is one important way to improve the productivity of oil and gas wells. These artificial channels increase ability of the reservoir rock for conducting hydrocarbons to the wellbore. In this study a new approach has been proposed for optimization of fracture half length in hydraulic fracturing operation. Also, this new method that is a combination of various fracturing geometry models has been proposed for modeling the hydraulic fracturing geometry. We have shown that there is a reasonable agreement between the result of pseudo 3D fracture geometry model and the predicted results from the proposed approach

Description
In the article we have reflected a relationship between the parameters of the research activities of scientific and pedagogical collectives and the characteristics of the educational environment in higher education. It is known that the research activities of scientific and pedagogical workers and teams - an integral part functioning of the higher education institution (and improving its efficiency is one of the most important problems). The authors proved that parameters reflecting research activity of scientific and pedagogical higher education of institution employees characterize the aspects of the educational environment as its latitude, intensity, social activity, coherence, mobility, stability, reliability and efficiency. It is caused by the fact that the research activities of scientific and pedagogical workers - a multifaceted social and cultural phenomenon. The idea of the diagnosis of the educational environment of a higher educational institution and its structural units, based on an assessment of scientometric indicators (criteria for research productivity), can be completely suitable for international and Russian requirements: the well-known Shanghai procedure shifts the emphasis on the evaluation of various aspects of the research activities in higher education; serious attention to assessing the research activity focuses and Russian technique diagnostic efficiency of higher education institutions. This is logical and soundly: if the educational environment of a higher educational institution is not a center of science, then it cannot have effectively and competitive graduates, because Research and pedagogical staff - the governing factor in the educational process. Based on previously developed models of research activities in scientific and pedagogical collectives, as well as on generally accepted models of educational environments, the authors have proposed a method for the diagnosis of the educational environment, based on an assessment of scientometric indicators - parameters reflecting the impact of the research activities of scientific and pedagogical workers. Obtained results may be the theoretical basis for further scientific understanding of the problem of increasing the productivity of research activities in higher education, as well as problems - increasing the competitiveness of educational environments. The practical significance of the results of this study - the possibility of their use in the system of socio-pedagogical monitoring - monitoring of productivity the research activities and effectiveness of educational environments. Methods of investigation: modeling, methods of the theory of sets and relations, methods of probability theory and mathematical statistics, methods of the theory of limits, methods of linear algebra and analytic geometry, multi-parameter analysis of the systems and methods of quality control (latent variables theory). Methodological bases of research: a systematic, metasystem, qualimetric, sociological and probabilistic and statistical approaches

Description
We have illustrated multiple factor analysis of the dynamic friction coefficient of the friction units in tribosystem and tribounits under laboratory conditions. As the tribosystem we had a model band-block brake with regime parameters of the control handle tension of the brake and brake work. By using the method of the mathematical planning of the extreme experiments, we have obtained functional dependence of the dynamic friction coefficient of the variable parameters in the form of a second-order polynomial, which adequately describe the processes under study. As tribounit at the micro- and nanoscale there was the reference change of the dynamic friction coefficient of the pair "Retinax FC-24A – Steel 35HNL" as a function of surface temperature, the values of which correspond to certain laws, based on the rise and fall of the characteristics of the dynamic friction coefficient. We have made the evaluation of the dynamic friction coefficient on the principle of the superposition with the multiple factor analysis of the following parameters: the process of forced cooling and heating; the processes of the polarization and depolarization in the contact patch of the micropoints of friction pairs; the type of the contacts of the micropoints depending on the work function of the electrons and ions from materials; the formation of primary and secondary structures on the surfaces of frictional contact; the destruction and restoration of the pellicles on surfaces, etc. We have analyzed the results of the studies of changes of the dynamic friction coefficient on the macro-, micro- and nanoscale and we have found the basic factors affecting its value

OPTIMIZATION OF WELL PLACEMENT IN WATERFLOOD PROJECT IN "X" FIELD NIGER DELTA, NIGERIA
DescriptionWater flooding used in secondary oil recovery to level up reservoir pressure can be enhanced in order to fit the reservoir conditions with the aim to optimally recover oil. One of the important optimization variables to realize this aim is optimal well placement. Various methods have been suggested for this problem. Among these is direct optimization, although accurate, is difficult due to the number of simulations required. Optimal placement of up to six injection wells was studied at the X field in western Niger Delta of Nigeria. Injection rate and injection time was also optimized and net present value (NPV) of the flooding project was used as the objective function. In this case study, it is shown theoretically and by means of Eclipse 100 that according to the basic elementary reservoir characteristics, optimal oil recovery is strongly dependent on well placement pattern and injection rate. Simulation results show that good sweep efficiency can be achieved with a regular pattern with an optimal well position

Description
In the article, we present the mathematical model of a ventilation system with variable air flow along the vertical axis of the reactor in the composting process. We have solved the problem of the choice of the method of supplying air to the bioreactor, reducing the temperature of the substrate along the axis of the bioreactor. The proposed method provides a reduction of temperature and moisture content of the gas phase, which leads to a change in the dynamics of the composting process. This article was prepared in the framework of the scientific project 16-48-230441 a(R) "Mathematical modeling of the processes occurring in the automated installation for year-round production of organic fertilizers in the conditions of the Krasnodar region", financed by RFBR and administration of the Krasnodar region

EXPANDING THE RANGE OF GLUTEN-FREE FLOUR CONFECTIONERY PRODUCTS BASED ON BUCKWHEAT AND QUINOA
DescriptionExpanding the range of flour confectionery products for people suffering from intolerance to wheat protein is relevant in the circumstances of import substitution. The domestic market of gluten-free confectionery products fully meets the demand of this category of people, which are dominated by sweet tooth children, requiring constant variety of confectionery. Therefore, the purpose of the work, which consists in expanding the range of pastry products based on buckwheat and quinoa, is relevant. The study presents a shortbread recipe based on buckwheat flour with different dosages of quinoa, a block diagram of the production and evaluation of the quality of the finished confectionery. Sensory evaluation of quality was carried out by a tasting analysis by a special system of scores: quantified indicators of quality - color, taste, smell, surface, shape and form in a break - is presented in the form of balls, followed by mathematical processing. We have defined physical and chemical indicators of quality biscuits, including moisture, alkalinity, absorption, fat and sugar content. Based on the assessment of quality of gluten-free shortbread we have set the optimal ratio of buckwheat flour and quinoa is equal to 70:30. The developed formulation will expand the range of gluten-free flour confectionery and can be adapted to the process and the equipment installed on the existing confectionery businesses
