Description
The work is done in a scientific and practical ways to minimize power losses in the transmission of electricity in the interregional distribution networks from the sources to the consumer by the use of tasks, ensuring the gradual improvement in the support program, not only from the standpoint of the efficiency of reduction of transported power loss, but also due to a significant decrease the complexity of the calculations. The resulting shortage of electricity power associated with its transfer to the electricity networks, has demanded the need to find possible ways of reducing the value of electricity losses during transportation, both by improving and by optimizing distribution net-works schemes. Consolidation into a single set of electrical equipment, called the power cluster is connected to the sources of power and energy consumption, make better use of new principles of control technology and the transmission of electricity, on the basis of an automated monitoring system, ensuring the redistribution of energy flows and optimize them. The process of electric power transmission and reduction in electric power loss can be considered on the basis of linear programming problems, and their modification in the form of a transportation problem, and as a result, the transport matrix. On this basis, manipulating the data table, we can find acceptable solutions, well and then determine the best of them. As examples, this work has carried out the study on the basis of the three methods - "northwest corner", the method of minimum unit cost of electricity transport, as well as the method of the potential. The use of these three methods yielded acceptable solutions, to identify the most appropriate for the number of steps carried out at the decision, to reveal that the winner is the potential cost method

Description
The article presents a staged scheme for granulation of solid fraction solids of fermented poultry manure (SF FPM) in an augered granulator. Granulation process of material has been reviewed in every stage of compression. The structural and mechanical properties of the pressable material were studied. It was revealed that SF FPM refers to pseudoplastic bodies, which when exposed to pressure exhibit anomalous properties. We present a rheological model of the motion of pressed materials in an augered granulator. We have modeled a mechanical model of actions at SF FPM. It was revealed that the compressible material at voltages generated in an augered granulator at the area of plasticizing was acting like an abnormal liquid. This liquid obeys the regularities of Newtonian liquids

Description
We have presented a table of analogues of mechanical and electrical quantities of a thermal power plant, which shows the relation between the useful power of the engine and mechanical efficiency, as well as the relationship between engine parameters and regime of its operation; we have also developed an electro-mechanical analogy, which helped to get the expressions linking the useful engine power with shaft speed, engine performance, coefficient of mechanical resistance and mechanical efficiency with speed, coefficient of drag and engine performance. Similar expressions were obtained for the relations of these variables with other sets of parameters. The article also shows corresponding graphs. The expressions for the maximum net power and corresponding speed of rotation was found. Thus, the efficiency isЅ. It is shown that in larger (compared with the extreme) speed, the mode is less efficient than with the smaller, for the same useful power. A method is presented to measure the important characteristics of the finished engine – motor operation and its rotational drag coefficient used in the resulting expressions

06.00.00 Agricultural sciences
Description27 introduced variety samples of rice from 8 countries were studied by the complex of biological, morphological, agronomic traits to select the most valuable genotypes for including them into breeding programs on development of cold tolerant rice varieties. It was found that the studied introduced varietal samples were characterized by variation in duration which varied from 120 to 182 days. Variety samples from Bhutan ATTEY, PARO DUMBJA (White) had shown response to photoperiod and the panicles didn’t appear in conditions of Krasnodar region. During the study there were selected high productive forms Obongbueo and Tinbubueo from S. Korea with grain weight 81.67 g / vessel and 74.43 g / vessel, respectively. According to results of research there were selected five cold tolerant samples Tong Jing 29 (China), Giza 178 (Egypt), Istigbol and Mustagillik (Uzbekistan), ZAKHA (Bhutan), evaluation result of which were on the same level with those of standard check variety Kuban 3, as well as those of samples with increased resistance IR83222- F8-14 and IR83222-F8-156 (Philippines), PARO DUMBJA (White) and THIMPHU DUMBJA (Bhutan). As a result of research there were selected three introduced rice variety samples Tong Jing 29 (China), Tinbubueo (S. Korea) and SR 30084-F8-156 (Philippines) which by duration, morphotype and agronomic traits are considered as candidates for further hybridization and breeding as sources of useful traits and properties

Description
Tomato is one of the most popular vegetables in Kuban. Every year, the area under this crop in the region occupies more than 11 thousand ha. Currently the State Register of Breeding Achievements approved for use in Krasnodar region, includes more than 90 tomato varieties and hybrids, however, the need for new, more productive varieties is not reduced. The important task of breeding is development of varieties and F1 hybrids with stable realization of the potential, with high level of yield ability, resistance to adverse environmental factors. In the southern regions of Russia for tomatoes, especially during flowering and fruit ripening, the most unfavorable abiotic environmental factors are excessive heat (air temperature 35 - 45 ° C or higher) and high solar radiation. Adverse temperature conditions often act as a deterrent in obtaining high yields, due to the flowers and fruits drop. The article presents the results of breeding activities of the last ten years (2007 - 2016) on development of new tomato varieties and F1 hybrids for different purposes As a result of studies there were developed four tomato varieties and one F1 hybrid that meet the requirements of production and are adapted to abiotic conditions of cultivation in open field in Kuban

DescriptionThe article presents the data of 40-year-old variety-trial cultivation of hybrid black poplar and balsamic sections, as a result of which addressed issues of selection range of appropriate varieties, their cultivation technology, aspects of agrotechnology and protection against pests. At the same time, it absorbed and non-forest land reclamation funds, in particular sandy and shell, lowhumus, floodplain soils. As a result, the five-year variety trials found that under the conditions of the Eastern Azov on humus shell rock underlain by low-mineralized groundwater on accessible depth for roots (up to 150 cm), the most highly productive and are stable clones of Euro-American poplar: Brabantika-175, Sanrau-59, a Moshnyi-236 and 195 , Bahel, ZS-33 Vernirubens, 60001/1, Caroline-162. In terms of growth, they are superior to the local Canadian poplar and other varieties of poplars. Resistance to environmental and biological factors of the environment most highly productive species and varieties of poplars are much higher than the low productivity. Culture of poplar planting might create unrooted plants directly on the silvicultural area, which reduces the cost of rooting plants at the nursery, their digging and transportation and provides a high survival rate. Culture of poplar are used for the afforestation of poor sandy forest-steppe zone arrays, often introduced as the main breed at shelterbelt afforestation

TO THE QUESTION OF THE ESTIMATION OF THE SOLAR ENERGY
DescriptionIt is known that today one of the promising areas to effectively solve issues of energy saving, is the introduction of renewable energy sources. Despite the fact that the current solar PV stations have the main drawback associated with the high cost, the prospects of their application in autonomous systems of electrosupply are evident when they are used in combined (hybrid) systems. In such systems there may be other types of renewable and traditional sources of electricity. In addition, they produce heat. We have disclosed prospects of solar industry, and also, for solar energy assessment, we have examined analytical expressions allowing defining the energy derived from solar radiation for specific surfaces. Calculations start from obtaining statistical data gathered at meteorological stations which keeps records of the intensity of the total (direct plus diffuse) radiation on a horizontal surface, and the intensity of direct solar radiation. The article presents features of the calculation taking into account the climatic and territorial conditions on the example of the Krasnodar region. The given calculation procedure is the first stage for designing solar power plants. Further, the total capacity is determined by electricity consumers, as well as the quality requirements of electricity, including continuity of supply, embarking to the construction of the block diagram electricity supply. In this scheme, we must provide primary and backup power sources. It selects the main equipment of solar power plant (solar panels, inverters, storage batteries)
