NEW SCIENTOMETRIC INDICATORS RESISTANT TO ARTIFICIAL “IMPROVEMENT”
Description
The article presents the new criteria suitable for the diagnosis of the productivity of research and the importance of its results for the scientific community, are resistant to artificially "improve". It is known that generally accepted measure of the productivity of research scientists is the h-index, which is calculated based on a statistical method of scree. This indicator is applicable to research teams (organizations). However, the h-index and a number of other scientometric indicators based on citation, are easy to be artificially increased (fraudulent schemes action). New scientometric parameters adequately reflecting the importance of research results, and not amenable (or very difficult to) to be artificially "improved" are therefore needed; moreover, it is recognized around the world: the true score (not fictitious) of the significance of the results of a research scientist for the scientific community - is a complex metrological (scientometric) task. The authors argued that such indicators are primarily index latitude demand for research results, as well as a number of other parameters of copyright. Despite the fact that authors indicators, the same as the h-index are based on citation, their large values indicate that the scientific community recognizes the results of the research activities of scientific and pedagogical workers; moreover, these indicators can be considered as a criterion to identify really promising (productive) researchers. The problem of adequate assessment of the productivity of research activities and the significance of its results, the authors consider in the context of the problems (larger problems) of the effectiveness of educational environments. The practical significance of research results lies in the possibility of their use for constructing criteriondiagnostic apparatus for monitoring research activities of scientific institutions (including higher educational institutions). Research methodology: systemic, metasystemic, probabilistic-statistical and qualitative approaches. Research methods: cognitive, structural, functional, and mathematical modeling; methods of graph theory, sets and relations; system-cognitive analysis; methods of quality control (theory of latent variables); methods of probability theory and mathematical statistics (first of all – a method of scree), methods of analytical geometry; methods of the mathematical theory of limits

THE STUDY OF THE EFFECTS OF RICE QUALITY ON THE EFFICIENCY OF ITS PROCESSING
Description
There 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

PROSPECTS OF RECEIVING AND USING LIGHT WATER
Description
It 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

USE OF TERMS “ASU” AND “IS” IN AGRICULTURE FROM THE POINT OF VIEW OF INFORMATICS
Description
The article deals with the issues of comparing the terms of ACS and IS with reference to automation in agriculture. In the technical literature, at conferences, in educational disciplines of higher education institutions, such terms as: information systems (IS), information technologies (IT), automated control systems (ACS) are often encountered. These terms are widely applied to the relevant objects in the subject areas under consideration. The area of coverage of the objects using these terms is very wide and in each case the definition of the applied term is either not specified at all considered self-explanatory, or the term is defined with various levels of detalization. In the latter case, the thoughtful researcher falls into some confusion or generally tries not to touch upon this question. In the article, on the basis of a review of known literary sources, it is shown which concepts are denoted by these terms when considering automation issues in agriculture. The subject of the study is the use of the terms IT, IS, ACS in works on automation in agriculture. The subject of the study is questions of comparison of the terms ACS and IS. The aim of the study is to indicate that automated IS is a more general concept than ACS

TO THE THEORY OF STRENGTH OF DIESEL ENGINE EXHAUST GAS PURIFICATION OF SOOT PARTICLES
Description
The problem of environmental protection from the contamination by toxic products, contained in the exhaust gases, is one of the most topical in the modern world. Nitrogen oxides and soot particles are the most toxic. Getting into the environment and the human body, they cause heavy chronic disease and significantly impair the quality of animal and plant products. The developed gas purification system SCR, the technology of plasma purification of exhaust gases have not found wide practical applications because of their high value. The study of papers dedicated to reducing exhaust gas toxicity shows that the use of combined means of purification, which usually include mechanical, thermal and catalytic methods of purification, is the most effective. Our work deals with the issue of purifying the diesel engine exhaust from fine particulate matter resulting in the combustion of fuel and oil motor partly. The article notes that the carbon is not magnetic, so the use of a magnetic field acting as an agent for the purification of exhaust gas from the carbon soot particles is impossible. The purification in a centrifugal field requires the creation of structurally complex centrifuges, so it is ineffective. We consider the possibility of purifying the exhaust gases from the soot particles in the electrostatic field. The device presents the collecting electrode, which is shaped as a cylinder, and an axial central electrode, which is mounted on an insulated spacer within the cylindrical body. The study deals with the physical and mathematical simulation of processes occurring in the proposed device of the purification of exhaust gases. The equality of the Coulomb force and the Stoks force determines the magnitude of the electrostatic field strength that is necessary for the purification of exhaust gas from the soot particles. We have identified the desired length of the collecting electrode

Description
The article is devoted to the estimation of the dependence of perennial grass herbage’s productivity on the dose and distribution of nitrogen fertilizers during the vegetation, as well as from the dynamics of the species composition by years of use. It was revealed that for cocksfoot-timothy grass mixture an increase in the rate of nitrogen fertilizer for every 10 kg of active ingredient leads to an increase of yield by 0.27 tons/ha. The selection of components of grass mixtures and rational fertilizer doses forms the herbage which provides a yield of about 7,0-12,0 tons/ha of dry mass and 58,1-99,6 GJ of energy exchange. It is established that competitive relations in grass mixtures are exacerbated with increasing doses of fertilizers. The timothy grass develops successfully in a mixture with the cocksfoot with a low level of mineral nutrition (N80). A high level of mineral nutrition speeds up the formation of single-species herbage - the cocksfoot. Meadow fescue grass provides sustainable yields on medium and high backgrounds of mineral fertilizers in combination with the cocksfoot. Recommendations for a nitrogen dose of more than 200 kg per hectare for fertilizing mixed grass crops with the cocksfoot and about 100 kg per hectare for clover-cereals mixtures without cocksfoot are suggested
