SIMULATION OF NONLINEAR COLOR OSCILLATIONS IN YANG-MILLS THEORY
01.00.00 Physical-mathematical sciences
DescriptionThe article presents the simulation of non-linear spatial-temporal color oscillations in Yang-Mills theory in the case of SU (2) and SU (3) symmetry. We examined three systems of equations derived from the Yang-Mills theory, which describes the transition to chaotic behaviour. These transitions are caused by nonlinear vibrations of colour, depending on the model parameters - the coupling constants and the initial wave amplitude. Such transitions to chaotic behaviour by increasing the parameters are characteristic of hydrodynamic turbulence. A model of spatial-temporal oscillations of the Yang-Mills theory in the case of three and eight colors. The results of numerical simulation show that the nonlinear interaction does not lead to a spatial mixing of colors as it might be in the case of turbulent diffusion. Depending on the system parameters there is a suppression of the amplitude of the oscillations the first three of five colors or vice versa - the first three five other colors. The kinetic energy fluctuations or shared equally between the color components, or dominated by the kinetic energy of repressed groups of colors. Note that the general property of physical systems described by nonlinear equations in the Yang-Mills theory and hydrodynamics is particularly strong in the formation of quark-gluon plasma and hadrons jets, when the Yang-Mills is involved in the formation of hydrodynamic flow. Note that there is a relationship between the Einstein and Yang-Mills theory, on the one hand, Einstein's equations and hydrodynamics - on the other. All of this points to the existence in the nature of a general mechanism of formation of a special type of turbulence - geometric turbulence

SIMULATING AND PREDICTING GLOBAL CLIMATIC ANOMALIES SUCH AS EL NINO AND LA NINA
01.00.00 Physical-mathematical sciences
DescriptionThe paper discusses the modeling and prediction of the climate of our planet with the use of artificial intelligence AIDOS-X. We have developed a number of semantic information models, demonstrating the presence of the elements of similarity between the motion of the lunar orbit and the displacement of the instantaneous pole of the Earth. It was found that the movement of the poles of the Earth leading to the variations in the magnetic field, seismic events, as well as violations of the global atmospheric circulation and water, and particular to the emergence of episodes such as El Niño and La Niña. Through semantic information models studied some equatorial regions of the Pacific Ocean, as well as spatial patterns of temperate latitudes, revealed their relative importance for the prediction of global climatic disturbances in the tropical and temperate latitudes. The reasons of occurrence of El Niño Modoki and their relationship with the movement of elements of the lunar orbit in the long-term cycles are established. Earlier, we had made a forecast of the occurrence of El Niño episode in 2015. Based on the analysis of semantic models concluded that the expected El Niño classical type. On the basis of the prediction block AIDOS-X calculated monthly evolution scenario of global climate anomalies. In this paper, the analysis of the actual implementation forecast of El Niño since its publication in January 2015 - before June 2015. It is shown that the predicted scenario of climatic anomalies actually realized. Calculations of future climate scenarios with system «Aidos-X» recognition module indicate that further possible abnormal excess temperature indicators of surface ocean waters in regions Nino 1,2 and Nino3,4 for 2015 may be comparable with similar abnormalities in the catastrophic El Niño of 1997-1998.

MODELING THE DYNAMICS OF THE MARKET SYSTEM
DescriptionIn the modern conditions of dynamic development of the market system, the economy, feeling polynomial enthusiasm and recessions, demands external influence, regulation, management. It isn't possible to realize an effective control system of economy without understanding of a consequence. The regulating structure represented by the state needs an effective system of the support of decision-making allowing to estimate the consequences of the made decisions before their direct realization. Use of modern methods of complex estimation for modeling of market system on the basis of trees of criteria and matrixes of convolution allows forming a static market model in the form of the functions of sensitivity interpreted as curves of supply and demand. However, the questions of creation of dynamic market system on the basis of these mechanisms weren't discussed so far. In this article the questions of possibility of modeling of dynamics of the market system built on the basis of mechanisms of complex estimation are discussed. Relevance of the chosen method depends on the possibility of preliminary formation of possible outcomes of an event in the form of the count on definition further of probability of transition to each of states on the basis of a complex assessment of the individual of "advantage" of such transition. An additional benefit of such approach is that fact that when forming market system from some contingent of participants with different behavior models for each of them there is an opportunity to create the scenario, and when receiving at a stage of modeling of result to reconsider the new created structure of structure of society

MICROSTRUCTURE OF MODEL SYSTEMS BASED ON FERMENTED RAW MATERIALS
DescriptionIn the research we have given a detailed description of certain structural components of the model system when adding fermented raw material into it. As the raw material we used collagen containing by-products of bovine animals of the 2nd category – lips and ears were used. The lactulose syrup and linseed flour were used as growth-promoting substances. The fermentation of the raw material was conducted by freeze-dried starter of the bacteria of Propionic Culture PS–4 and Probio–Tec ВВ–12, and also bacterial concentrate Bifilact-Pro. The fermentation parameters: the temperature 37°С, the time of the fermentation is 3 hours. The changes, taking place in the tissues under the biotechnological processing, were established with the method of the histological samples test. As the result of the conducted microstructure tests of prototypes it was determined that in the biomodification process under the influence of the propionic and bifidus bacteria marked changes occurred in the histological structure of modeling systems in the comparison with the control sample. At the same time it was ascertained that under the influence of the ferment processing a loosening of collagen fascicles happens to isolated fibrils and their fragmentation occurs. As the result, when composing protein compositions an emulsion (which is homogeneous by the structure) comes out. In the future it is recommended to use the emulsion in the receipts of boiled sausages and minced half-finished goods

MICROBIAL COMMUNITIES OF KARPOSPHAERA AND PHILLOPLAN OF SOME PLANTS OF GROSSULARIACEAE FAMILY
DescriptionThe article presents the results of the research of microflora composition of the leaf surface, the surface of fruit and flowers of Ribes nigrum, R. niveum, R . rubrum and Grossularia reclinata. The research was carried out in the seasonal dynamics from 2007 to 2014. The authors used the method of print for isolating microorganisms from plants. For convenience of calculations and contamination comparison of different environmental niches of plants the number of selected microorganisms was counted on the surface of 1 cm2. It was found out in the article that microorganisms on the surface of lamina are distributed unequally. The number of microorganisms on the bottom surface of the foliage in all periods turned out to be higher. The greatest number of microorganisms was recorded in autumn and reaches the highest value in October. The number of microorganisms on fruit surface increased with ripening and was the highest in July. The quantity on the flowers varies considerably throughout the flowering and is represented minimally compared to other plants niches. The study revealed species-specificity of microorganisms and the host plants. At the same time, long-term study of the microflora of plants belonging to one family made it possible to reveal species that are typical epiphytes

THE MATHEMATICALLY BASED CHOISE OF VISCOELASTIC IN SHUNT GLAUCOMA SURGERY
DescriptionThe dramatic lowering of intraocular pressure (hypotony) is developing during glaucomatous surgery due to the formation of the new aqueous humor outflow. The calculations of the flow in the fluid balance parameters have shown, that for the normal intraocular pressure maintenance in the postoperative period the fluid flow out of the anterior chamber should not exceed 0,04 microliter in minute. The intensity of the aqueous humor outflow through the shunts with different parameters does not depend on the shunt length. The shunt with the inner hole radius 0,025 mm is the most safe as it provide the less outflow. The experimental comparative study of the static viscosity of the most widely used viscoelastics in ophthalmological surgery was carried out. It was stated that used in eye surgery viscoelastics on the basis of 1%, 2% and 3% sodium hyaluronate possess the viscosity, that differs in 10 and 100 times and has significant influence on the flow intensity out of the anterior chamber when the new outflow tracts are formed. The mathematically based choice of the most optimal relationship between the viscoelastics physical parameters and the inner hole size of the shunt type glaucoma drainage devices was established. Shunt with the inner hole radius 0,05 mm and simultaneous use of 2% and 3% sodium hyaluronate solution is the most safe for the maintenance of the eye tonus during the first 5 days after glaucoma surgery. The presented correlation allows to increase the safety of the surgical treatment of the patients with the refractory glaucoma

01.00.00 Physical-mathematical sciences
DescriptionWe propose a mathematical model of ion transport binary salt in electroosmotic flow in a capillary. The capillary is open on one side and immersed in a vessel of large volume, in which the concentration of the solution is maintained constant, and the other side closed ion exchange membrane. The walls are considered wettable, i.e. the solution adheres to the walls. This means that the mathematical modeling used to rate the condition of sticking. We study the boundary value problem for a coupled system of equations Nernst, Planck, Poisson and Navier-Stokes equations. Used boundary conditions of general form. The mathematical model is based on the general laws of transport and contains no adjustable parameters. Using this model, the basic laws of ion transport salt solution liquid flow, the emergence and development electroconvection, distribution of concentration of salt ions in the capillary with a small change in time, ie, in the initial (transitional) regime. We have identified the presence of ion-exchange membrane surface electroconvective vortices and their influence on the mechanisms of ion transport of salt and fluid movement in different areas of the capillary. A feature of the capillary transport is to the right of the vortex region stagnant areas with a higher concentration of ions

THE OPERATED EYE HYDRODYNAMICS MATHEMATICAL MODELING FOR OPTIMIZATION OF SURGERY THECNIQUE
DescriptionAcceptable values of the drainage hole parameters in the shunt glaucoma surgery were calculated by means of mathematical modeling of different conditions of eye hydrodynamics. The operation method was designed with provision for pressure gradient, rate of the aqueous humor outflow, and the values of intraocular pressure in early and late postoperative period. The balance of liquid in eye was calculated in mathematical model as ordinary differential equation in accordance with flow resistance of every section. The data received by using mathematical model has shown that allowable rate of aqueous humor outflow is gained with the hole diameter of 0,025 mm. This mathematical model should assist to the better understanding of physical processes describing the eye hydrodynamics, should benefit to the operation quality and should create the base to the clinical studies

Description
This article is devoted to solving the critical task of improving the reliability of the power systems for agricultural processing plants. The article’s material is exploratory in nature, reflected in the fact that the proposed mathematical models for the analysis of groups of high-voltage induction motors will allow to investigate various modes of symmetric groups of asynchronous motors more effectively. We present the analysis of the existing mathematical models of induction motors considering the design features of such machines that directly affect the dependence of resistance and inductance on the rotor current frequency. The assumptions taken into consideration to obtain a more accurate mathematical model of the induction motor are also formulated. The article provides a comparison of different reference frames used in the mathematical modeling of asynchronous motors. It is proved that the use of the generalized coordinate vector for mathematical modeling of asynchronous motors is the most optimal approach. The equivalent circuit of asynchronous deep-bar motor in generalized vector coordinates derived in the work is used for analysis of transient behavior as well as the steady state operation. The results of the study are suitable for transient analysis of electrical power supply systems of agricultural enterprises with large number of high-power electric motors, for example, CHP of sugar processing plants and grain elevators
