06.00.00 Agricultural sciences
DescriptionThis article discusses the results of the study to determine the impact of different primary tillage and herbicide against weeds in winter wheat agrocenosis. The task of the research was to determine the impact of primary tillage (moldboard plowing and surface treatment) factor A and herbicide (Lancelot) factor B on the agro-physical and agrochemical soil properties. It has been established that the content of productive moisture during the growing period of winter wheat in 0-100 cm of soil layer didn’t depend on the method of tillage. Introduction of herbicide Lancelot boosted the moisture reserves in soil compared to the control type, in the herbicide-free type the weeds absorb the large amounts of moisture. Surface soil treatment did not have negative effects on soil agro-physical properties and its structure in comparison with moldboard plowing. Number of agronomically valuable aggregates on moldboard plowing is 85.2 - 87.5%, on surface one is - 86.2 87.5%. Density of composition and waterproof aggregates under surface treatment didn’t defer to tillage. Accumulation of wet and dry mass by weeds regardless to the way of soil tillage declined to a minimum when introducing the herbicide Lancelot. The high yield of winter wheat was obtained on this type. Mathematical processing results have shown that due to factor A (main soil tillage) to moldboard plowing the average productivity is 57.5 kg/ha, on surface one is 56.0 kg/ha, i.e. the difference between treatments is 1.5 t/ha (with NSR05 on factor - 2.9 t/ha) is insignificant. To factor B (herbicides) on control the productivity is 54.5 kg/ha, introduction of Lancelot increased the productivity to 59.5 t/ha, i.e. the increase was 5.5 kg/ha at NSR05-by the factor B-2.9 t/ha, i.e. is significant. Thus, the present soil treatments had no effect on yield of winter wheat in ordinary black soil. The use of herbicide Lancelot has produced the harvest increase in 0.5 t/ha on average for 2 years

VORTEX TURBULENT FLOWS IN ATMOSPHERES OF PLANETS AND ON THE SUN
01.00.00 Physical-mathematical sciences
DescriptionIn this work, we consider two types of vortex currents-cyclones and anticyclones in the Northern and Southern Hemispheres. Numerical modeling of turbulent flows of these types uses the model of the planetary boundary layer developed by the author. The purpose of the study is to test hypotheses about the influence of the Coriolis force on the formation of cyclones and anticyclones in the northern and southern latitudes. The first hypothesis on the direction of circulation in cyclones was verified in the case of axisymmetric radially converging and vertically rising turbulent flows with a natural Coriolis parameter and viscosity. From the obtained data of numerical experiments, it follows that the current in the northern latitudes circulates in a counter clockwise direction, and in the south - in a clockwise direction, in full accordance with the observational data. Thus, we have shown that a cyclonic flow is formed in a turbulent radially converging flow under the influence of the Coriolis force. The second hypothesis on the formation of anticyclones was verified in the case of radially divergent and vertically descending turbulent flows. Because of numerical experiments, it was established that in this case, the current in the northern latitudes circulates clockwise, and in the south - in a counter clockwise direction, which corresponds to observations for anticyclones. To test the effect of the cyclone (anticyclone) center velocity on circulation, a nonstationary 3D model of turbulent flow was developed. Within the framework of this model, flows in cyclones and anticyclones moving at a constant speed, as well as in shear flow, are studied. Some types of loop protuberances on the Sun are explained by the presence of a vortex turbulent flow starting in the bowels of the Sun and encompassing the chromosphere

SPECIES COMPOSITION OF ALGOFLORA IN AGROCENOSIS OF KUBAN
DescriptionSpecies composition and abundance of soil algal flora were studied in the Central zone of the Krasnodar region on crops of crops cultivated by various technologies. In the algal flora of the studied area, 48 species of soil algae and cyanobacteria from 28 genera and 18 families, 7 classes and 4 divisions were identified. The largest and numerous in number of species are the departments: Cyanophyta and Chlorophyta. Extensive delivery: Oscillatoria, Gloeocapsa. They account for 22 % of the total number of species. A negative effect of herbicides on number and species composition of soil algae was noted. In all variants of their application there was no form of Klebsormidium flaccidum (Kützing). The number of species of Chlorella vulgaris Beyer. was low, Botrydiopsis arhiza Borzi. It is believed that these species of algae can be used as bioindicators. The positive effect of mineral fertilizers and the aftereffect of introducing organic matter on the soil algal flora have been established. In these variants the deleterious effect of herbicides was reduced. According to the calculated regression equations, the applied mineral fertilizers to a greater extent weakened the negative effect of herbicides on the total number of populations than the aftereffect of introduced organics

Description
Studying natural phenomena in all their diversity, humanity worked experienced in every field of science the model of perceiving the world and methods of obtaining information. The development of science currently cannot be imagined without research on the intersection of its regions. This article presents the results of the automated systemcognitive analysis of the size of atoms from the main characteristics that are of research at the interface of General chemistry elements and intelligent systems. Dependence of nuclear radius, mass and of the atom and the charge number are identical in shape and size, which is probably connected with the linear increase of these parameters in the Periodic system of chemical elements. There is also a similar form of the dependences of radii of atoms from the factors ex and x, because these factors are interrelated. The obtained results of the ask analysis have confirmed the theoretical assumptions and the formulae of the dependence of main characteristics of the atom

ANALYSIS OF EFFICIENCY OF PRODUCTION OF PLANT GROWING PRODUCTS OF CJSC "CENTRALNOE", KRASNODAR
DescriptionThe article gives an analysis of the efficiency indicators for the production of plant growing products using the example of the reporting of CJSC "Centralnoe". We have revealed the mathematical model for the analysis of economic efficiency of production of plant growing products. In the work there were considered the following indicators characterizing economic efficiency: labor intensity; profit from the sale of fruits; profitability; cost of 1 centner of fruit; yield; costs for the maintenance of fixed assets used in production. Various models of the dependence of indicators characterizing economic efficiency on the above indicators were considered. As a basic culture, we have selected fruits, because these cultures are the main types of products for this organization. The authors singled out a reliable and qualitative mathematical model of the relationship between profit on sales and yield, labor intensity, and self-worth. Model could be used to determine the economic efficiency of organizations engaged in agricultural activities. The relevance of the study is due because these problem is one of the most important for all organizations that produce plant growing products. The agrarian sector has certain peculiarities, therefore, when determining of the economic efficiency of a separate economic entity and the industry as a whole, it is necessary to take into account these features

ALGORITHM FOR OBTAINING MATHEMATICAL MODELS OF ELECTROMECHANICAL DEVICES
DescriptionAn algorithm for obtaining a complex of mathematical models of electromechanical devices, which can then be formalized and implemented in software, is proposed and described. Until recently, the implementation of this algorithm was possible only with the manual derivation of all expressions, which significantly hampered the work of researchers. The appearance of such programs as Maple, Mathematica and MathCAD provided the possibility to automate the process of obtaining analytical calculations that allows calculating any modes of any types of electromechanical devices, reduces the likelihood of errors and allows you to change accepted assumptions and designations in the developed models. The choice of the MathCAD program (in comparison with Maple and Mathmatica) can be justified by the fact that MathCAD has the most convenient interface, allowing not only to perform mathematical calculations, but also to present the results in ordinary mathematical notation. The analytical results obtained in MathCAD can be immediately included in numerical models

ACTUAL PROBLEM OF DEVELOPMENT IN SYNERGETIC PARADIGM
DescriptionIn particular, the paradigm of complexity, which claims to be the dominant post-non-classical philosophy and science, also came under the trend of diversity. The paper discusses conceptual foundations of the particle physics. This theme is examined in connection with problem of logical and philosophical analysis of physical language and its usage in cognitive procedures. Features of synergetic as interdisciplinary scientific direction, the concept of a universal evolutionism, value of information in nature development are discussed. Methodological basis of the process of integration of scientific knowledge is the interdisciplinary direction of the research which important component is the synergetic. It plays an important role in the concept of coevolution realization which considers mutual relation of the person and the nature, the micro- and the mega-world. The article demonstrates that having revealed the laws of functioning of complexly evolutionizing, nonlinear systems, synergetic thus posed the fundamental questions of both epistemological and ideological and value nature
