INFLUENCE OF MELAPHEN ON AGROBIOLOGICAL AND TECHNOLOGICAL CHARACTERISTIC OF SAVINION WHITE GRAPE
DescriptionHereby we present the results of the research devoted to study of influence of growth modulator called melaphen on the technical brand of gapes such as Sovinion White and its agro-biological characteristics. The research was conducted in 2014-2015 using fruitful grape Sovinion White of 2004 planting as a subject in agro farm “Yuzhnaya” of Temruk in the Krasnodar Region. Melaphen is a type of melamine salt of bioximethilphosphin acid. It evokes complex influence on the energetic complex of vegetation cell in all three stages of vegetation. The chemical was applied mechanically by a tractor sprinkling. The square of tested patch is 2 hectares. Melaphen usage was 6,7 ml to 1 hectare . Norm of liquid applied was 700 liters to 1 hectare. Three times the chemical was applied during vegetation: before blossoming, grape growth phase (grapes the size of a pea) and before the grapes ripen. As a result it was estimated that three times chemical application of melaphen to Sovinion White in dose 1. 10-9 in period after blossoming of grapes and before the grapes ripen led to more saturated accumulation of sugar in juice of the grapes and also to faster ripening and harvesting, larger mass of grape bunch amount of harvesting from a bush. Besides, in the tested option growing processes are accelerated and pigmentation agents are accumulated faster in the leaves and embryo infestation in winter sleeping core is boosted at larger scale. Better harvest quality leads to better wine materials quality. Application of melaphen provides higher economical efficiency

DescriptionThe article scientifically substantiates and experimentally confirms the high efficiency of the nano biological feed supplement "NaBiKat" in diets of broiler chickens of the "Cobb-500" cross. The supplement is a new complex with a mixture of rice germ films, green tea gallocatechin in chelated form, and forty-nine trace elements in chelated form, including biosoluble form of silicon. The main function of silicon is to be involved in a variety of intermediate exchange reactions as a catalyst and to ensure normal flow of vital mechanisms as a coupler helping to combine cellular molecules into a whole functioning structure. Silicon begins to act on the body when getting into the lumen of the gastrointestinal tract with the feed. It activates the enzyme system of the body and in ionic form is absorbed by kind of ordinary diffusion along almost the entire small and large intestine beginning from the jejunum. The supplement studied has been proved to improve the morphological structure and biochemical properties of blood, to enhance metabolism, redox processes, and the level of natural resistance. The broilers fed the supplement "NaBiKat" in the experimental groups have been found to have a higher concentration of macro- and micronutrients in blood. The nano biological silicon-containing supplement as a compound of in the composition of feed for chickens had a positive effect on their growth and development

DescriptionFor the purpose of preservation of soil fertility at relatively low economic expenses, we have conducted researches on optimization of doses and combinations of mineral fertilizers by cultivation of field corn hybrid called "Krasnodar 382" in a stationary field experiment of the Department of agrochemistry in the training farm "Kuban", in the conditions of the leached chernozem of Central zone of the Krasnodar region. The main impact on receiving high-quality corn gives the content of plant nutrients in soil. Our researches showed that the application of the complete fertilizer in various doses has had influence on the content of essential plant nutrients in the soil. The maximal values of the content of mineral nitrogen, available phosphorus and exchangeable potassium during all phases of vegetation have been got in options with double N60P60K40 and triple N90P90K60 dose of the complete fertilizer. Sufficient supplying the soil with plant nutrients by fertilizing has entailed the enhance of corn yield. Great crop of corn has been reaped during the experiment. After three years of researches, the productivity has reached averaged 58,7 cwt/hectare. The greatest productivity has been received in the option with application of triple and double dose of the complete fertilizer and amounted 68,5 and 68,0 cwt/hectare, what is 47% and 45,9% more, compared to the option without any application of fertilizers. The main substance, which defines nutritional value of corn, is proteins. Application of fertilizers under the conditions of our experiment has promoted enhancing the protein content in corn. The application of mineral fertilizers has promoted increase of the content of crude protein in corn. Maximal it was in option with application of the complete mineral fertilizer in the double dose of N60P60K40 – 9.6%, when reaped protein has amounted 6,5 cwt/hectare. Therefore, it is possible to conclude that it is most expedient to fertilize field corn with the dose of N60P60K40 and N90P90K60

DescriptionThe influence of dissociation / recombination of water molecules is important for understanding electroconvection processes, as some authors believe that the emergence of new carriers + H and − OH , and can lead to a reduction in the space-charge and, consequently, to electroconvection disappearance. However, as shown in [5], the dissociation of water molecules, although it reduces the space charge and increases the threshold fall potential jump at which begins electroconvection, yet it persists and effectively mixes the solution. This article is devoted to mathematical modeling of electrodiffusion of four types of ions at the same time (two salt ions as well as + H and − OH ions) in the diffusion layer in electromembrane systems with perfectly selective membrane under the joint influence of violation of electrical neutrality, and the reaction of dissociation / recombination of water molecules, development of mathematical models of these processes, building efficient algorithms asymptotic and numerical analysis for different types of electrolytes. The work proposes a new mathematical model of the process of transfer of salt ions in view of the space charge and the dissociation / recombination of water in the form of a boundary value problem for a system of ordinary differential equations. This system is reduced to a form convenient for numerical solution. We have calculated the required additional boundary conditions for the electric field. Numerical and asymptotic solution of the boundary value problem and physico-chemical analysis of the influence of dissociation / recombination on the transfer of salt ions is expected to devote the next part of the work

06.00.00 Agricultural sciences
DescriptionDuring the last century, in the biosphere occur expressed processes of soil degradation due to anthropogenic influence, which seriously change of top layer of soil. The agricultural landscape is allocated of noticeable accumulation of various wastes at expense of growing of food crops and grazing of farm animals, as well as due to mineral wastes generated in process production of building materials and fertilizers from natural raw. According to physical and chemical characteristics of wastes of plant origin and natural-raw wastes constitute a non-toxic highly dispersed connection with an admixture of different undecomposed organic and mineral substances. Specificity of physical state is determined there of high dispersion, which is represented by system particles of colloidal substances distributed in various environments. Colloids of natural-raw wastes are characterized by a low rate of diffusion; do not penetrate finely porous membrane of cell structures, different very nonequilibrium insolubility and specific chemical composition. For example, phosphogypsum is characterized by high concentration of sulfur and calcium, and trace amounts of entire table of D.I. Mendeleev. Organic wastes are made by variety of chemical compounds and high concentration of carbohydrates, proteins, fats and other organic substances

ZIRCONIUM EFFECT ON THE STRUCTURE AND PROPERTIES OF TINI BASED ALLOY
DescriptionWe have performed a mechanical activation of TiNi powder; as a result, PN47T26TS27 powder after mechanical activation is flat discs ranging in size from 10 to 30 microns. We have developed a composition technology "steel - material with shape memory effect" by high-velocity oxygen-fuel spraying of mechanically activated powder based on TiNi. We have determined the optimal processing parameters to ensure a nanostructured surface layer. We have estimated the process parameters of highvelocity oxygen-fuel spraying. The basic parameters are: propane flow rate 60-85 l / min, that of oxygen 120-160 l / min, flow rate of powder and carrier gas (argon), distance and angle of deposition, and movement speed of the torch, the rotation speed of the coated workpieces. We have carried out macroand microanalysis of surface layers of Ti-Ni based alloy, obtained on proven technology. We have studied the effect of TiNi doping with a third component Zr. The simulation allows us to predict the possibility of using surface modification of products with SME material TiNiZr under certain conditions of temperature and to determine the desired composition of the coating, which provides a positive effect. We have made tests on steel 45 with a surface-modified layer TiNiZr under dry friction conditions, during which there is a significant increase in temperature, we have confirmed the effect of improving the wear resistance

01.00.00 Physical-mathematical sciences
DescriptionIn this study, we investigate the problem of the emission of gravitational waves produced in collisions of particles submitted to the singularities of the gravitational field. A system of non-linear parabolic equations describing the evolution of the axially symmetric metrics in the Ricci flow derived. A model describing the emission of gravitational waves in the collision and merger of the particles in the Ricci flow proposed. It is shown that the theory of the Ricci flow describes the problem of black holes merge, consistent with Einstein-Infeld theory, which describes the dynamics of the material particles provided by the singularities of the gravitational field. As an example, we consider the metric having axial symmetry and comprising two singularities simulating particles of finite mass. We have numerically investigated the change of the metric in the collision and merger of the particles. The initial and boundary conditions using the exact solution of the static problem, so the collision persist particularly metrics caused by the presence of particles. In numerical experiments determined that the collision of the particles in the Ricci flow leads to the formation of gravitational waves, similar in structure to the waves, registered in the LIGO experiment. Consequently, we can assume that the observed gravity waves caused mainly by transients associated with the change in the metric of a system. The influence of the parameters of the problem - the speed and mass of the particles, on the amplitude and intensity of the emission of gravitational waves was numerically simulated. We have found chaotic behavior of gravitational potentials at the merger of the singularities in the Ricci flow

DescriptionAn experiment was conducted to examine the effect of fatty acid concentrate (FAC), as a new source of energy and carnitine on performance, physiological condition and meat quality of broiler chickens. In experiment there were four groups of 80 chickens of cross Hubbard each (males: females=40:40) in age period 0-41 days. 1 group (control) received in during the periods 0-14, 15-28 and 29-41days, sunflower oil (SO) respectively 5.34%, 5.50%, and 6.10%, group 2 received the same amounts of FAC instead SO, 3 group - mixture SO:FAC (50:50), 4 group -FAC + 0,25% carnitine. Final body weight: 1 group = 2574±29 g, 2 group FAC= 2553±27 g 3 group SO + FAC = 2531±34 g., 4 group FAC+0,25 carnitine = 2520±34 g. Feed conversion, digestibility of nutrients, blood hematology and biochemistry, the condition of organs, meat quality and cutting of carcass of chickens on FAC had no any differences from the same signs in chicks on SO. Carnitine had a positive effect on chicken growth only in the period 0-14 and less 15-28 days; in the period 29-41 days daily gain was below, than that in 1-3 groups. Canitine reduced the content of liver fat. Outcome: FAC is a satisfactory source of energy, comparable with vegetable oils. The price of FAC is 30% lower in comparison with sunflower oil and soybean oils, therefore its use in broiler poultry farming instead of vegetable oils will be of great economic importance

DYNAMICS OF THE GEOMAGNETIC FIELD AND REVERSALS IN THE SATELLITE MODEL
01.00.00 Physical-mathematical sciences
DescriptionThe article deals with the problem of changing the polarity of the geomagnetic field in the satellite model. It is assumed that the central core of the earth magnetized and surrounded by a number of satellites, each of which has a magnetic moment. Satellites interact with a central core and one another by means of gravity and through a magnetic field. It is shown that satellites distributed in orbit around a central core in such a system. It displays two models, one of which on the outer orbit satellites interact with each other and with a central body - the core and satellites, located on the inner orbit. The central body can make sudden upheavals in the fall at the core of one or more satellites, which leads to the excitation of vibrations in the satellite system, located on the outer orbit. It is shown that the duration of phase with constant polarity and upheaval time depends on the magnitude of the disturbance torque and core asymmetry. The second model contains two magnets subsystems and the central core. The rapid change of the geomagnetic field polarity detected on the basis of paleomagnetic data is modeled based on the Euler theory describing the rigid body rotation. In this model, there are modes with a quick flip of the body while maintaining the angular momentum. If the body has a magnetic moment, when there is a change coup magnetic field polarity. This leads to the excitation of vibrations in the satellite subsystems that are on the inner and outer orbits. Numerical simulation of the dynamics of the system consisting of the core and 10-13 satellites was run to determine the period of constant polarity magnetic field
