01.00.00 Physical-mathematical sciences
DescriptionIn this article, we discuss various issues related to the formulas approximating the distribution function of prime numbers pi(x). This question has occupied many scholars, but the exact function is well approximated function pi(x) over the number of positive integers not. Based on certain hypotheses, we present a new function s(x) is very well approximated pi(x). The above article hypotheses are so important that their numerical validation and refinement for the lengths of the segments more in 1014 - one of the main areas related to the problem of approximation of the function pi(x) throughout the series of natural numbers. After analyzing the behaviors and constructs many functions, we are building the basis of the function s(x), which is well approximates the function pi(x) throughout the series of natural numbers. We also present a table of values for x, less or equal 1022 for the difference of s(x) - pi(x)

INFLUENCE OF THE LENGTH OF FRUIT VINES ON THE YIELD AND QUALITY OF MOLDOVA GRAPES
06.00.00 Agricultural sciences
DescriptionThe article presents the results of studying the effect of different lengths of fruit vines with the same load wintering buds of bushes on the yield and quality of Moldova grapes. It was found that the biological indicators of fruiting Moldova grapes improved by lengthening fruit vines, taking into account weather conditions. Shortening the vines increases germination and fruitfulness degree base buds and reserve buds. Productivity is increased by lengthening fruit vines. It is determined by the degree of fruitfulness buds of the vine, the development of floscules of wintering buds, bunch and berries weight, number of berries in bunches. The optimum is pruning vines to 10-12 buds. Harmonious taste, weight of bunches and berries, transportability factor fixed high yield of grapes standard (85,6-86,4%) with different length of fruit vines. The highest productivity of leaves makes pruning fruit vines to 10-12 buds. The strength of shoot growth and volume growth of bushes reduced at an elongation of the fruit vines. The more moderate growth of shoots observed at long (10-12 buds) pruning vines. There is no significant difference to the degree of maturation of shoots with different length vines. In order to increase the yield of Moldova grapes in the central zone of the Krasnodar region expedient cut fruit vines to 10-12 buds

DEFINITIONAL PROBLEM OF FORMATION OF THE “MUSLIM WORLD” CONCEPT
10.00.00 Philological sciences
DescriptionThe peculiarities of representation of the concept “Muslim World” in modern English discourse are regarded in this article. Based on the achievements of cognitive linguistics and cultural linguistics, it is possible to research the concept of “Muslim World” as a phenomenon of the English linguistic culture. Different approaches to the definition of the term “concept” are studied. The article describes definitional analysis of lexical items “Muslim” and “World” in modern English dictionaries. Based on these results, it is concluded dictionaries present the term “Muslim”, first of all, as a human - a follower of a particular religion. We can say the concept “Muslim world” is presented in the social and conceptual knowledge as one of the manifestations of the human world and is used in relation to the reality of cultural and historical unity of the Islamic nation. This concept serves as an image of reality in the system theory of knowledge. The further studying of the Islamic world, as definition is possible to make with the mutual enrichment of the social reality of other peoples. “Muslim world” in accordance with the principle of universal connection of phenomena reveals its potential in the modern world and it becomes possible to establish relationship between people, nature and society, as well as their mutual influence on each other

STUDY OF THE INTERACTION OF POLYSTYRENE-AZO-O-PHENOL-AZO-RHODANINE WITH ZINC IONS AND CADMIUM
DescriptionSince the industrial revolution a huge amount of pollutants emitted annually into the water most of which is occupied by toxic metals. These metals widely distributed in the environment and of accumulation of a threat to human health. It is known, that cadmium and zinc at high concentrations have a negative impact on nature. In modern wastewater treatment technology we widely use polymeric sorbents with chelating properties. The use of polymeric chelating sorbents (PCS) usage allows separating individual or group trace elements from large volumes of solutions of complex composition, lowering the limit of detection, eliminating or reducing significantly the impact of macrocomponents which increases the cleaning efficiency. The article presents the results of a study of conditions of interaction of zinc (II) ions and cadmium (II) with PCT - polystyrene-azo-o-phenol-azo-rhodanine. We found the optimal values of the conditions for zinc (II) ions and cadmium (II) sorption. We investigated the effect of interfering of the macro- and micro- water components with the sorption of the ions studied. Maximum desorption of metal ions is achieved by washing the concentrate with 10 ml of 2M hydrochloric acid. The data indicate availability of the investigated sorbent for concentration and separation of zinc (II) ions and cadmium (II)

HYPOTHESIS OF THE ORIGIN OF THE UNIVERSE, SOLAR SYSTEM AND EARTH
DescriptionIt is assumed that in the primordial state of the Universe was missing the elements of matter, it was submitted to electromagnetic photon field in a broad frequency band. Photons with energy ε=1,02 born MeV electrons and positrons, and photons with energy ε=1,87 born МeV protons and antiprotons. The Association of protons, electrons and essential spectrum of photons created a sustainable hydrogen atoms and neutrons. Association of hydrogen atoms led to the creation of hydrogen clusters, and merging neutron – neutron creation of clusters (pulsars). As a result, the concentration of photons in the Universe decreased and the universe were compressed. The gravitational interactions between the hydrogen and neutron clusters was coming off of a mass of matter from both. The torn mass of hydrogen clusters were created on the planet. Separation of the mass from neutron clusters led to the neutron exposure of the main hydrogen clusters and loose parts from him (future planets). The latter, being closer to the main hydrogen accumulation, under the influence of neutron flux were redesigned to all elements of the periodic table. The article describes nuclear reactions convert one chemical element to another. After irradiation of the primary hydrogen clusters of neutrons and the emergence of the heavy and superheavy hydrogen, started fusion reactions with the release of photon energy and the transition of hydrogen clusters in Stellar condition. They began to glow. The selection of the photon energy of the Stars led to the increase in the concentration of photons in the Universe, the increase of the pressure and the expansion of the Universe, which is what happens at the present stage of its development. Combining antiprotons, electrons (positrons) with the required spectrum of photons created sustainable antihydrogen and antineutrons, and their clusters – clumps of antimatter in the Universe

RESISTANCE OF THE SOIL UNDER THE INFLUENCE OF HORIZONTAL DISK WORKING BODY
DescriptionTillage plays an important role in the production of cereal and grains. The issues of improving the methods applied for soil treatment aimed at improving its quality significantly influencing crop yield have been considered. Reducing of all types of costs: energy, labor, money was also taken into consideration. In this article, based on numerous studies we have proposed to use the effect of oscillatory motion in the working body of tillage, improving the design of tillage machines, reducing the metal consumption of the machine, the intensity of the process while increasing quality of work. The article reveals issues related to embedding of the new tillage of the working body running in a horizontal plane and having special tabs (blade), allowing it to make a reciprocating rotational motion. This working body provides the undercutting of a soil layer and root system of weeds, the crumbling of the soil layer and its interaction with the working surfaces of the blades. The conditions of the sliding soil layer on the surface of the working body and reducing the pressure of the reservoir to the working body are proposed. It decreases the compression of the reservoir and the tractive resistance. We have substantiated the conditions for reciprocating rotational motion of the proposed disk of the working body in the working plane close to the horizontal, when interacting with a layer of the soil

Description
Studying the problems of the development of Russian business education today seems urgent in view of the serious impact of globalization factors on world markets, as well as taking into account the factors of global economic recession and to the undeclared war sanctions restrictions against the Russian economy and not having under itself no justification other than political. The article presents the results of the analysis of positive and negative factors in the development of the Russian business education, because of which it was concluded, that for the further development of the Russian system of business education needs a new approach. It should be based on the formation of the conceptual model, taking into account the current realities in the Russian economy. The authors set out to become the key provisions of the new approach, namely to ensure the growth of professional and specialist competencies required functionality; the study of «effective practical techniques», a reasonable reduction of the duration of the MBA program of study; distribution of specialists trained in powers depending on their positions. The above provisions allowed forming a conceptual model of business education, which is based on four practical degree professional training laid. In addition, the article justified criteria for evaluating the quality and composition requirements for modern business education program. The proposed in the article new approach and the conceptual model of the development of Russian business education are targeted at practitioners who want to gain more knowledge in a limited period and very reasonable cost of education. The further development of the Russian business education system in the very near future will show the validity of this approach

EDUCATIONAL TECHNOLOGIES, DEVELOPING VISUAL THINKING IN THE TEACHING OF BIOLOGICAL DISCIPLINES
DescriptionThe article discusses issues related to visual thinking and educational technologies. We have noted the importance of visual thinking in the teaching process at the higher education institutions and defined its main functions. We have considered information technology for courses such as “History and methodology of scientific agronomy”, “Cytogenetics”, “Genetic monitoring”. The article substantiates basic postulates for the formation of visual environment: the ability to collect the material in accordance with the task and to define the basic accents, and navigate through all of the work; the ability to match the artwork to the selected research topic. As the technology, we have regarded the method of sketches or visual notes, and the method of visual metaphor. The method of sketches or notes was the basis for the creation of electronic databases with images of plants in different works of art. Visual notes allow visualizing the educational information by translating verbal elements of this information into visual that is "to be able to think visually." Works of art, as illustrative environment, have several meanings in training courses: an exemplary or motivation; illustration as a source of information for the analysis of the phenomenon under study; visual, that is paintings or works of art as an illustration of the student response, as a result of its self search. The visual metaphor is used to explain the material, understanding and comparison. Both methods are: the method of sketches and visual metaphors that allow the subject to learn, analyze, communicate and draw analogies with the subject area and to look for new images
