PREPARATION OF GRAPHENE MATERIAL WITH BENZIMIDAZOLE FRAGMENTS
DescriptionThe new benzimidazole-functionalized graphene material based on graphene oxide (GO) and 3,3',4,4'- tetraaminodiphenyl oxide (TADPO) was obtained under one-step hydrothermal synthesis conditions. According to IR spectroscopy and elemental analysis, as a result of the reaction, benzimidazole (BI) rings are formed, and the mass content of nitrogen is 12.3%. The new graphene material is characterized by excellent electrochemical efficiency in a threeelectrode supercapacitor. As a result of the redox activity of BI cycles the specific capacitance reaches 286 F/g at the scan rate of 2 mV/s, which is substantially higher than the reduced graphene oxide (RGO) sample obtained under similar conditions without using TADPO (159 F/g at 2 mV/s)

Description
Currently, during the period of international sanctions against Russia, most of the domestic organizations found themselves in a rather difficult economic situation, having lost investment from outside. This is due not only to the general situation that has developed in our country, but also to the poor financial situation of many domestic organizations. The lack of compliance of financial indicators with normative, high level of accounts payable and unprofessionalism of employees only exacerbates this situation. The article analyzes the theoretical and conceptual provisions for forecasting the investment attractiveness of organizations. In the course of the research, the concept of "investment attractiveness" was clarified and supplemented. The article has a research character, which is expressed in the fact that it examines foreign and domestic methods of forecasting investment attractiveness by the example of «Fanagoria-Agro», which is stably positioned in the market and attractive to investors. It was revealed that in order to increase the investment attractiveness of the research organization, according to the methods developed by the author, the amount of assets should be reduced by reducing the receivables. A set of measures to increase the investment attractiveness of «Fanagoria-Agro» was developed and the economic feasibility of its implementation was justified

THE ASSESSMENT OF COMPLEXITY OF COMBINATORY METHOD OF NUMBERS’ FACTORIZATION
01.00.00 Physical-mathematical sciences
DescriptionThis article is devoted to the assessment of the calculating complexity of combinatory method of numbers’ factorization. The content of combinatory method is explained in the article of the same name published in the journal issued in November 2016. The author supposes that the reader has learnt its content and knows the basic notions of theory of calculating complexity of the algorithms. The following results of the learning of the given task are expounded in this article. The algorithm of combinatory method permits to accomplish the parallel calculations. Graph of any order is the separate structure, because its initial data are determined independently from the other graphs. So, the calculating complexity of the task about the factorization of numbers in the predetermined interval of the positive integers is defined by the complexity of the most laborious graph. The analysis of the graphs’ structure allows to state that it’s the graph of the third order. In any graph both branches of the first level give the separate structures- partitive graphs of the first level with independent input data. So, the calculating complexity of the graph complete is determined by the maximal complexity of the graph of the first level. The givenat random interval of positive integers stays without changes, if we observe the sequence of the adjacent intervals. In the results it’s stated that the assessment of complexity of combinatory method as well other present methods of numbers’factorization is exponential. In this aspect the combinatory method doesn’t compete with other actual methods. However, evaluating the scientific significance of the algorithm, the decisive factor is not the calculating complexity, but its originality, which permits to explain (if not to discover) any properties of the positive integers. In the conclusion of the article the author describes the advantages of combinatory method, permitting to appreciate the degree of its scientific novelty

Description
We have considered the most important direction of development of enterprises of the military-industrial complex: modernizing production capacity and technical re-equipment of these enterprises. The relevance of this issue in recent years has increased significantly due to changes in the terms of military development (economic hardship, sanctions, etc.). We have developed an economic-mathematical model of the choice between modernization and radical technical re-equipment of enterprises. The article has an analysis of this model taking into account the financial factors in this choice. The use of the developed economic-mathematical apparatus in practice allows increasing the efficiency of technological development of enterprises of the military-industrial complex

FEATURES OF NUMERICAL MODELLING OF LANDSLIDE PROCESSES ON THE EXAMPLE OF THE CITY OF SOCHI
DescriptionDevelopment of infrastructure of Sochi as mountain resort has demanded increase in transport means of communication and development of territories, difficult for construction. Construction works cover territories of the Kudepsta and Adler districts and also Krasnaya Polyana. The main problems at design near Greater Sochi are landslides and landslide processes and also high seismicity of territories. Besides, the increased technogenic loadings on many sites have led exogenous processes to activization. At unforeseen activization of landslide processes it is required to develop actions for strengthening of the existing constructions or construction of new protective designs in the shortest possible time. However, there are problems of modeling of a landslide situation. On the example of construction retaining at the portal constructions of a railway tunnel near Sochi modeling of landslide processes on the basis of natural observations (monitoring) is considered and also actions for stabilization of slope processes are described

DescriptionThe results of comparative analysis of three white muscat grades of grapes Viorika, the Muscat de Yaloven and the Muscat onitskan according to the biological indicators of fructification, productivity, quality of berries, mechanical structure of bunches, suitability for manufacture of direct extraction juice and dry wines are depicted in the article. All studied grades differ by high percent of fruiting runaways and high factors of fruiting and fructification. The highest factors of fruiting and fructification of runaways are reflected at grade Viorika, and the lowest - at a grade the Muscat de Yaloven. Biological indicators of fructification of runaways according to the length of a fruit spear are high and rather levelled at all grades. That is why, depending on bushes forming, it is possible to apply short and average (6-7 buds) length of vine cutting. Biological indicators of fructification of runaways from angular buds and sleeping buds are high enough, that shows to good regenerative ability of studied grades. Grades Viorika and the Muscat de Yaloven are tall, and the Muscat onitskan is average height. Degree of ripening of runaways at grades Viorika and the Muscat onitskan is good, at a grade the Muscat de Yaloven - satisfactory. Productivity of grades Viorika, Muscat de Yaloven and the Muscat onitskan is 77,94; 81,52 and 72,72 centner/hectares, and efficiency of runaway - 199,5; 193 and 221,9 with a significant difference between grades on both indicators. The exit of a mash at grades was 77,5-79,4 %. According to the contents of solids, sugars and acids, grapes of all grades correspond to requirements for manufacture of high-quality direct extraction juice. From grapes of these grades, it is possible to produce high-quality direct extraction juice under the name of ampelographic and blended grades. Sampling estimation of dry wines from grapes of these grades fluctuates from 7,6 to 7,8 points: 7,8 (Viorika), 7,7 (the Muscat onitskan), 7,6 (the Muscat de Yaloven)

PECULIARITIES OF USING OF PLANT RESIDUES FOR OBTAINING COMPOSTS
06.00.00 Agricultural sciences
DescriptionUsing of organomineral composts to preserve fertility and restore ecological functions of chernozem soils in the Krasnodar territory is necessary. Their composition depends on the properties of chernozem soils and can include various wastes of industry and agriculture. The main component of compost can be organic wastes of livestock, and plant residues and mineral additives are additional compost components. Peculiarities of the interaction of the components of the organomineralic mixture, which including manure of cattle and phosphogypsum, are considered in the work. In the interaction of organic particles of cattle manure and phosphogypsum particles, structural formations are formed where the phosphogypsum particles are enveloped by particles of cattle manure. The experience of composting this organomineral mixture with various crop residues of crops was carried out. Plant residues according to the intensity of decomposition in composts can be represented in the next row, beginning with more decomposed ones: sugar beet> winter wheat> winter barley> corn> sunflower. The composts obtained were characterized by a well-aggregated structure with a predominance of particles 1-2 mm in diameter, good aeration, low density (1.01-1.10 g / cm3), and favorable humidity (22-25%). The structural factor of composts with different plant residues ranged from 3.1 to 4.3 units. The best physical properties were compost, including plant residues of sugar beet, the worst - sunflower. The combination of an organomineral mixture with various plant residues contributed to a decrease in alkalinity of the substrate, a slowing of the mineralization of organic matter, restraint of ammonification processes, and an increase in the content of total nitrogen and phosphorus
