ON THE NUMERATIONS OF THE FINITE PARTIALLY ORDERED SETS
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)

VARIATIONS OF CULTURAL CONCEPT OF “LOVE” IN THE MODERN SONG DISCOURSE
10.00.00 Philological sciences
DescriptionThis article is dedicated to solving the problem of language and culture relationship in the modern society. Concept “love” is the main subject of the article; the author shows its examples in popular stage songs. There are five variations of love from the psychological and sociological point of view in the article. The author depicts how they are used in the song discourse. According to the research data the author consider that all variations of love in the lyrical song genre are not equally frequent. So while erotic love is almost everywhere, selfish love isn’t so popular. Moreover, the author concludes the cultural level of the whole nation can be defined with its creative arts. Furthermore, nowadays there is clear decadence of culture in English-speaking countries

Description
Fracture geometry depends on stresses and rock properties in hydraulic fracturing operation. Poisson’s ratio imports directly in the calculations related to formation stresses. The most important reason for limiting fracture height is the natural stresses contrast resulting from the differences with Poisson ratios. Without this difference, fracture would have largely uncontrolled height. The goal of this study is mathematical investigation of the effect of Poisson’s ratio on the formation stresses that is necessary to select value of breakdown pressure in hydraulic fracturing operation. In this article, a mathematical model has been coded using “MATLAB” software for prediction of stresses in the various layers. This designed program is able to present both digital and graphical output results for different values of Poisson’s ratio. At the end, stresses exerted on the different layers of the several real oil reservoirs have simulated and breakdown pressures have determined

Description
The article is devoted to the study of enzymesantioxidants contained in horseradish root. The article provides a detailed analysis of the sources of information, aimed at clarifying the content of enzymesantioxidants contained in horseradish root, grown in the Astrakhan region in the autumn and summer. During the analysis of the literature, it was found that the content of enzyme-antioxidants in the root of the horseradish is not constant and depends on climatic conditions, planting time and harvest time. The content of antioxidants in the root of horseradish grown in the Astrakhan region in the summer-autumn period was studied using by the method of A.N. Bach and A.I. Oparin. 2 g of horseradish roots contains the number of enzymes - antioxidants able to expand for 30 min (1,547 • 100) / (20 • 1) = 77.35 mg of hydrogen peroxide in 1 min - 2.56 mg. 1mkmol As hydrogen peroxide is 0.034 mg, in 2 g horseradish contains 76 E enzyme - antioxidants (or E 38 1 g horseradish). The results of this work will form the basis for the creation and study of new enterosorbent with antioxidant functions. Enterosorbent prepared by adsorption on starch antioxidants such as peroxidase, catalase, and ascorbic acid, from aqueous extracts of plant material

Description
The article studies the influence of polymeric in the form of formers and growth regulators on the growth and development of rice plants when grown in saline conditions. We controlled the effect of salinity on grows regulators and vigor, seed germination, root and shoot weight, the content of photosynthetic pigments parameters, induction curves of delayed fluorescence, the indicators of structure of harvest, grain yield. It was found, that pre-sowing seed soaking in solutions of polymer grows regulators has a stimulating effect on the growth and development of rice plants in the early stages: we significantly increased germination and emergence, dry weight of root and shoot compared to control. At different stages of ontogeny rice, the absolute content of pigments in the leaves and the relationship between the individual variants change. The absolute content of pigments in leaves and their relationship between experiences at different stages of ontogeny change. In the period of intensive vegetative growth from seedling stage the content of total chlorophyll is maximum, and by the end of the growing season it decreases. It can be assumed that the salinity of the substrate significantly reduces the productivity of photosynthesis in young plants, possibly due to imbalance of ions in the cell, the older it gets – the weaker the phenomenon is and even becomes reversed. The second maximum IR ZF increases during the growing season from germination to flowering, then decreases to the beginning of ripening in all embodiments. The same dynamics is characteristic of the magnitude of the proton gradient in the membranes of chloroplasts tylakoids. Salt protection effect of growth regulators on grain yield is significant on both backgrounds of mineral nutrition

APPLICATION OF EMF SHF IN PROCESSING TECHNOLOGIES FOR VEGETABLE MATERIAL AND SECONDARY RESOURCES
DescriptionThe article analyzes the proprietary methods of processing of vegetable raw materials and secondary resources with the use of electromagnetic fields (EMF SHF). Analysis of the database of Rospatent World Intellectual Property Organization led to the conclusion that EMF SHF used in the processing of vegetable raw materials in the following processes: drying, reduction of microbial contamination (decontamination), juice production and extraction. It is established that the application of EMF SHF is the most effective in preparation for drying a plant raw material and not directly at the stage of drying, thus reducing the loss of heat-labile active compound in the drying process, and therefore obtain a finished product of higher quality and nutritional value. The patented methods of extraction of vegetable raw materials extraction process performed that extracting directly EMF SHF does not allow pre-hold inactivate enzymes contained in the raw material and lead to undesirable oxidative and hydrolytic processes, and hence a decrease in the yield of extractable substances in the extract and the deterioration of its quality . Therefore, as in the case of drying plant material, EMF SHF can be more effectively used in preparation for an extraction process. Based on the analysis, it was concluded that the relevance of developments in the field of technologies of processing of vegetable raw materials and secondary resources using EMF SHF at the stage of their preparation for such basic processes - drying, extraction, etc.

The article is devoted to actual problems of ecological monitoring of conditions of small rivers in the North Caucasus and southern Russia. We are giving here the results of researches of natural and economic conditions and the current state of the river Nalchik near the city of Nalchik, which is typical for many small rivers. The materials of engineering researches and inspections of the territory of the urbanized areas of the river are brought with the detailed analysis of the results of the destroyed and broken areas. We describe the causes of the destruction of man-made protective and regulatory structures and the factors of their impact on the water protecting coastal zone and the hydrological regime of rivers. The effective method of regulation of short sites of the small rivers with use of groins and flexible biopositive nature protection technologies is offered. According to the complex research effective measures to improve the ecological state of the rivers on the example of Nalchik are offered. The rationale for the development of environmental monitoring in all urbanized coastal zones of small rivers and their cadastral registration is made. The main findings of the analytical and experimental research on different areas specific to the small rivers of the North Caucasus and southern Russia are brought here

Description
Macrodeficiency of polymeric materials, including the pervasive one, is a consequence of the development of initial microdefects which appear in polymers both due to external factors and during their processing. In the article, the problem of the detection of structural microdeficiency of various polymeric materials through an assessment of their structural parameters is solved. The considered materials possess approximately identical degree of crystallinity (60 – 66%), but different density. The express assessment technique of polymeric materials microdeficiency by the sorption method with the use of the academician M. M. Dubinin’s theory of volumetric micropore filling is developed and evaluated. On the basis of a quantitative assessment of sorption processes in polymeric materials, including elastomeric compositions – rubbers and rubberized fabrics, the existence of the initial local microdefects arising in the course of synthesis is established. In real polymeric materials, including elastomeric compositions – rubbers and rubberized fabrics, the existence of the initial local microdefects arising in the course of synthesis is established (the number of microdefects n varies from 1x1017 sm-3 to 6x1019 sm-3 , and the rated linear size k – from 2 nm to 7 nm). The general reduction of microdeficiency in rubberized fabrics in comparison with initial rubber is revealed and rationalized

Description
The article is devoted to the analysis of positions of some philosophers who negatively estimate a role of equipment in human lives and societies. It discusses the philosophical concepts of E. Yunger, F. Yunger, M. Heidegger, K. Jaspers, etc. Besides, the authors of this article address to A. Schopenhauer, F. Nietzsche, M. Makklyuen's heritage. In this work it is shown as methods of formalization and symbolization in science are transferred to areas of humanitarian knowledge and spiritual life, impoverishing them, turning "the understanding thinking in estimating". Calculation becomes a sign of the mechanized reality in which education, work, household submit also to the principles of mechanization. Extrapolation of mechanics to all the spheres of human existence leads to destruction of the humanistic principles: the world as mechanical system is the world where one element can be replaced with another where each part represents only object for studying and manipulation. In the article we also describe tendencies of transformation of people into masses on the basis of the rational estimating tradition of Modern times. Thus, in this work the problems menacing to the essence of "human" are being put and the message for further searches of the way of permission of the question of dehumanization in connection with technical development is formulated, when it is impossible to refuse it completely
