Description
Sunflower is one of the most important oilseed crops, which are of great economic importance in Russia and in the world. It is very adaptive crop in terms of climatic conditions range, for that reason it is cultivated on a vast territory of the Russian Federation in various weather conditions. Sunflower oil has high nutritional and taste qualities, it is used numerously in food and is applied in various fields of food industry. The biologically active linoleic acid, phosphatides and fat-soluble vitamins A, D, E and K, which are of great nutritional value to humans, are contained in the oil. According to its calorific capacity, sunflower oil is on the first place among vegetable oils. Due to biological characteristics of sunflower, the Krasnodar region is the most favorable region of the Russian Federation for obtaining high and stable yields of this crop. However, here the drought is observed during the summer period and it affects adversely the productivity and quality of sunflower seeds. The increasing of resistance to unfavorable weather conditions is possible only based on detailed study of physiological features of productivity formation and seeds quality that is highly important task in view of the current geopolitical situation in Russia. One way of solving this issue is the appliance of the growth regulators, possessing anti-stress activity that improve the quality of sowing seeds and increase the productivity and plant resistance to stressful environmental factors. These drugs include growth regulator called Furolan, which was created in KubGTU and is certified for use in Russia. It is not toxic and is used in nano-dozes, there is no its residual quantities in the products and environment. Furolan has a positive effect on physiological and biochemical processes, improves the productivity of plants, their resistance to unfavorable growing conditions by increasing the resistance to dehydration as well as to the risk of fungal diseases

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

Description
The work is scientific and practical in nature, same as the discussed process of optimization of power losses in power networks based on the use of the transportation problem, namely the rules of the minimum element of the transport matrix, which is a valid solution. The mechanism of the improvement of the obtained feasible solutions to the tasks focuses on using the potential method, assigning each row and column of the matrix their corresponding potential. Using a basic variable and manipulating the elements of the transport matrix according to a specific algorithm, we implement the construction of a new support plan. Based on the plan and its acyclic, we build two cycles and determine the values of the estimates between direct and indirect transportation costs per unit of output. The resulting algorithm makes it easy to program all computational operations and quickly obtain the result of the optimization of power losses in the design of the electricity network, thereby reducing the economic and technological costs. As a result of joint use of transportation problems and potential method, we could find the optimal solution based on improved solutions more efficiently, and a scheme of optimal electric network. As consumers, in practice, there may be urban and agricultural, industrial enterprises, regional and district subordination, including industrial, agricultural and individual customers

HARDENING AND SOFTENING OF CLAY SOIL
DescriptionHardening of clay soil manifests in the form of increase of the resistance of sample to shear deformation. The shear tests of normally compacted and overcompacted soils give values of peak strength at small strains and long-term strength at high. A shear test with constant strain rate of deformation (CRD) with continuous recording of resistance encounters uneven resistance change and the cyclical rate of change of resistance (RCR). The identification of cycles of the SIS allowed us to divide the deformation in each cycle for elastic and inelastic, corresponding to the ascending and descending branches of cycle. On an interval of the total resistance, the increases of the increment of inelastic strain are positive up to some critical value of the total deformation of the sample at which their sum reaches a maximum. This maximum is adopted as a measure of hardening. With further shearing of the sample, inelastic increments are negative, and their sum is monotonously decreases and reaches negative values for the total destruction of the sample. This value is taken as the softening. A symptom of total failure of the sample is the decline of absolute values of inelastic increments of resistance to zero. In general, the trend of the increments of inelastic and elastic increments of the resistance of the sample indicates the development of the destruction of the soil sample on the sliding surfaces and, in particular, yielding of the total surface. The sum of elastic increments of the resistance monotonically increases throughout the shear

DescriptionImproving the quality of Russian cognac is of great national importance. It should be noted that about 80% of Russian foreign brandies made from aged cognac distillates. To obtain high-quality products necessary technical-chemical control of production starting from the vine and the conditions of its growth. For a comprehensive evaluation of the totality of important factors: climate, relief, soil and variety. It is important to add that this grading must be accompanied by the release of environmental macro zones with viticulture specialization. In this regard, there has been conducted a soil-cartographic survey of lands of ACE "Fanagoria" in the Temryuk district of the Krasnodar region. Evaluation took place in view of all 4 factors, notably the soil factor; and the content of lime in the soil and the degree of salinity of soils. Soil analyzes were carried out in FGBNU Anapa ZOSViV SKZNIISiV using the latest equipment generally accepted methods for determining indicators of soil characteristics. The purpose of the research - to give a detailed description of the survey area, as well as highlight the boundaries of environmental macro zones for the cultivation of grapes brandy. During the research, it was found that for the selection and evaluation of raw material zones for brandy production we must take into account soil and climatic optimum performance to get quality brandy raw materials

DEFORMATION MODEL OF SAND MICROSTRUCTURE
DescriptionThe deformation model of sand soil that takes into account the formation of clusters of particles, and method of measuring its characteristics is suggested. The physical basis of the method is the effect of the stepwise increasing of the sand probe at the odometer pressure by the constant rate of loading and the continuous measuring of deformation. The analysis of settlement and its rate has been allowed to determine the microstructural characteristics of the two-order deformation model of sand. According to the proposed model, with compression of the probe in odometer compaction of the sand takes place due to local strains on the sliding surfaces. The sliding surfaces allocate clusters of sand, and the separated layers of clusters are registered by device in the form of steps of deformation. Layer formation of clusters is initiated by the rigid stamps through the largest mineral grains. Cluster layers create the asymmetric microstructure of the sand probe, its compaction is non uniform but also anisotropic. At the initial interval value of the pressure, the formation of primary clusters occurs, and once they cover the entire probe volume, the compaction of the sand is by crushing them on the secondary smaller cluster sizes. The change of mechanism of the compaction is manifested in the sharp decrease of the settlement rate. The compaction process continues while a larger increment of pressure at each step. The deformation model allows compute the pressure value at which the compaction of the sand reaches the theoretical limit
