01.00.00 Physical-mathematical sciences
DescriptionIn the article, we have suggested a general mathematical model of non-stationary and non-isothermal process of a binary electrolyte transfer in dilute solutions in an electro-membrane system (EMS), taking into account the joint action of gravitational convection, forced convection and electro convection in potential dynamic mode. This model is a boundary problem for a system of two-dimensional quasi-linear Navier-Stokes equation and Nernst-Planck-Poisson in partial derivatives equation. We have developed a theory of similarity of the process of heat and mass transfer in electro-membrane systems, specifically, in a desalting channel of electro dialysis apparatus, taking into account joint actions of concentration polarization, space charge, gravity convection, forced convection and electro convection. It is shown that the criterion of electro convection does not directly depend on the initial concentration, and, therefore, electro convection occurs at any initial concentration. At the same time, the criterion of concentration convection linearly dependents on the initial concentration, and, therefore, at high concentrations, concentration convection prevails, while at lower concentrations, the role of gravitational convection begins to fall whereas the role of electro convection increases. The theory of similarity of the process of heat and mass transfer in the desalting channel of electro dialysis apparatus built in this work taking into account the joint action of concentration polarization, space charge, gravity convection, forced convection and electro convection is important for engineering calculations, for scaling the results of experiments in an electro-membrane cell for industrial electro dialysis water desalting apparatus

THEORY OF SOCIAL MOTIVATION AS TOOL TO INCREASE SOCIAL PERFORMANCE IN SUB-SAHARAN COMPANIES
DescriptionThis article is about the theory of social motivation as a tool to increase social performance in Sub Saharan countries. So in the first part we will retell the theoretical understanding of motivation and its limits and then the explanation of the concept of social motivation as an alternative to complete the existing and old form of motivation. The second part of the article will talk about social performance and how to measure it. Several techniques are available for measuring performance of an employee. But the difference is in the sources of traits or qualities to be appraised. Jobs are different and have different requirements and different opinion of the management too. The practice is difficult sometime because of different kinds of workers (factory workers, executives or salespeople), which cannot be measured with the same indicators all the time. In this article we will see some theoretical and practical models of performance appraisal based on effectiveness and efficiency at work with concrete indicators. Also the readers will understand how social motivation, when well used in a company can increase the performance and transform the work place into a livelihood place for all stakeholders. And the article will end with the conclusion in which we have a piece of advice and literature references

EFFECTS OF GROWTH REGULATORS ON ROOTING CUTTINGS OF SYRINGA (PHILADELPHUS L.,PHILADELPHACEAE)
DescriptionIncreased range of Syringa in landscaping is a topical issue. They are very decorative shrubs, more and more widely used in landscape design. Study of vegetative propagation of plants, with the use of growth regulators, was conducted to identify the most perspective stimulator and to reduce the terms of the finished product. Syringa refers to bad rooting cultures. However, the methods of green propagation of cuttings with the use of growth stimulators not only propagate a culture, but also increase the yield of landing products. The article considers the technology propagation by cuttings of this promising shrub. It also shows the effect of growth stimulators: radifarma and HB-101, used for soaking of cuttings. According to the research, we have found an apparent benefits effect of the processing of cuttings with the stimulators on growth and development of root system. The analysis of the tables of rooting rate of cuttings shows the positive development of cuttings in the processing of the growth regulators. We have obtained the experimental data allowing to define which varieties distinguished by the greatest rooting and duration rooting among all the studied cultivars. Thus, the studies show that the use of growth stimulators with propagation of Syringa cuttings is an effective way of reproduction

06.00.00 Agricultural sciences
DescriptionThe article presents the characteristics of the mechanical composition of clusters, the chemical composition of grape juice and fresh grapes and wine tasting evaluation of three varieties of table. We have identified the following uvologic indicators of clusters of cultivars Flora, Nisina and Anyuta: structure - 90.0; 91.5; 87.3; addition - 8.0; 6.6; 10.8; structural - 6.4; 5.4; 8.1; berries - 17.6; 15.0; 10.4. In the studied berries of grape varieties the mass concentrations of sugars and titratable acids were in the range 18,1-23,5 and 0,73-0,78 g/100 cm3 respectively. The combination of sweetness and acidity causes high taste properties of grapes. In grape berries of Flora and Nizina the concentration of fructose was two times more than glucose. Differences in the content wine, malic, lemon and succinic acids in berries varieties of Flora and Nizina were insignificant. In the berries of Anyuta variety, the concentration of lemon and succinic acids was more, malic was less than other varieties. Most of the studied varieties of berries contain malic and wine acids. More of cations of potassium, sodium, calcium and magnesium then in other varieties and it contain less than Anyuta berries. The difference in the content of various cations in the berries of varieties of Flora and Nizina is negligible. Tasting score of fresh grape of Flora variety was 7.0, Nisina - 7.8 and Aniyta - 7.6 points

Description
The article presents the ecological characteristics of soil types and forest cover of the Red October forestry of the State Unitary Enterprise of the Republic of Adygea. We have defined their relationship and the division into groups of forestry and environmental values. A complex combination of bioclimatic factors, parent rocks and topography has led to a large diversity of soil cover. We have revealed that different soils have different degrees of erosion on sloping hillsides, ravines, and steep slopes are dominated by strongly eroded soils. The most common form of physical degradation of soils of the red October experienced forestry is seal root layer observed on heavily used areas and pastures. Also, we found that poorly structured soils containing little humus are prone to compaction. Methods of rooting out areas after clear cutting of forests lead to secondary soil degradation. It especially enhanced if, at the moment of stressing, the soil is in the waterlogged condition. Therefore, at reforestation we should use different reclamation processing. And this leads to the difficulty of their use in reforestation. It is established that intensive anthropogenic activity leads to degradation of soil and forest cover of the study area

REVISITING THE RICE SALT RESISTANCE (REVIEW)
06.00.00 Agricultural sciences
DescriptionThe total area of saline soils of rice irrigation systems in the Kuban region reaches almost 80 thousands hectares. Salinization and alkalinization here become a limiting factor for cultivating rice and companion crops. In this regard, the tolerance of plants to soil salinity is a current problem of plant breeding that attracts the attention of many agricultural researchers whereas it is necessary to increase the yield in saline soils. Salt tolerance of crop plants is defined by a combination of properties which are based on the specific adaptation mechanisms. These mechanisms differ in nature and are associated with different levels of structural organization of the plant – from molecular to organismic one. The study of adaptation mechanisms at different levels of structural organization of plants is very important for increasing yield in saline soils. This article is a review giving a detailed analysis of plant salt tolerance research, particularly rice, which addresses the issues of inhibition of plant growth under saline conditions, the mechanisms of salt tolerance, the achievements and development of this branch of scientific research, as well as the application results of work found in the scientific literature

OPTIMIZATION OF GRAPE GROWING TECHNOLOGY BASED ON USING THE METHOD OF YIELD PROGNOSIS
06.00.00 Agricultural sciences
DescriptionThe article highlights the questions of preliminary determination of the yield of vineyards, grape harvest prediction method to determine the optimal length of fruit cutting of shoots and load bushes wintering eyes, kidneys examined productivity index wintering buds (CP), which shows how many inflorescences have an average for each left eye escape when cutting to length, including the dead. It was found that the yield of grapes has a great influence the degree of differentiation of inflorescence of rudiments in the central buds overwintering buds. From the moment of laying the harvest of grapes in hibernating little eyes in the form of embryonic inflorescences until commercial harvest takes two growing seasons. During this period the generative organs of grape plants are affected by many factors of the environment. Heterogeneity was found of buds along the length of one-year matured shoots. It is expressed in the fact that many grape varieties fruitfulness buds at the base of the shoot are much lower compared with upstream eyes. A certain death of wintering buds (primarily, the main kidney) at the end of the growing season, before the autumn frosts. The main reason for the death of buds during the growing season - from defeat fungal diseases. Taking into account the percentage of deaths of buds proposed a new exponent forming embryonic kidney main inflorescence - productivity index of buds by the ratio of embryonic stems to the number of buds, including the dead. Thus, annual forecasting of grape harvest next year to cutting the bushes by the proposed method makes it possible to scientifically establish the optimal cut length of shoots and fruit load on the bush eyes. This helps to realize directly the potential of each variety and vineyard site and get maximum yields even in years with low fruit tab formations
