SMALL MAMMALS OF THE TAMAN PENINSULA
DescriptionIn the present study, fauna of small mammals of the Taman Peninsula is analyzed. It is shown that the complex of rodents and insectivores inhabiting the study area differs considerably from the adjacent continental areas and is an isolate. Structure of its fauna and population resembles that of the steppe parts of Crimea and, at the same time, North-West NearCaspian areas. Analyses of variation of the D-loop regions of mtDNA in yellow-bellied mouse Sylvaemus witherbyi, as well as certain peculiarities of the species diversity, show the priority of faunal and genetic connections of the Taman Peninsula’s mammal fauna with the North-West Near-Caspian one

SEGREGATION OF THE PLANT HEIGHT AT INTERSUBSPECIES HYBRIDS OF THE SECOND GENERATION RICE
DescriptionThe article presents the results of the genetic analysis of the trait ‘plant height’ for six crosses involving the forms related to different subspecies of rice. There have been estimated the types of inheritance and a number of genes, which assist to determine this quantitative trait. We have found out that the variance of the trait ‘plant height’ is determined by 3-5 pairs of genes having additive and dominant activities and the degree of dominance reduces in case the variance among parental forms increases. The non-allelic interaction of the genes of the initial forms produces transgressive dwarf and tall forms. The cross ‘Lampo’x’Virazh’ showed the highest degree of transgression in ‘plant height’ due to short height of both parental forms (61.7%), but the frequency of transgression was larger than that of the cross ‘Lampo’x’Komandor’(17.6%). This combination (‘Lampo’x’Komandor’) produced more tall forms (up to 135 cm). The segregation of a great number of tall forms into F2 testifies that the parental forms of these hybrids vary in the allelic state of several pairs of genes, whose various combinations form phenotypes with a longer stem. Thus, the semi-dwarf feature of the varieties ‘Lampo’, ‘Komandor’ and ‘Virazh’ is determined by various non-allelic genes

ESTABLISHMENT OF THE RUSSIAN OILBANK PREMIER AS ONE OF WAYS TO INCREASE ENERGY SECURITY IN RUSSIA
DescriptionThe article deals with the energy security of Russia in conditions of sanctions and the globalization of the modern economy in the world community. It is substantiated that energy security is the main factor of political and socio-economic stability of each state. Russia is not an exception. For many years it has been the world's largest net exporter of oil and gas, mainly due to the weakness of the economic system, the main problems of the oil refining industry are considered, given The definition of energy security, the energy security of Russia is analyzed in the conditions of the crisis. An estimation of the export of domestic goods is given, the reserves of the regions are considered according to the level of extraction of oil resources, the rating of the largest oil companies is determined by the level of average daily oil production. It is concluded that for a successful export, the redistribution of significant oil reserves between regions within the country will require a relatively long period, not one or two years. It was revealed that the level of domestic production is not fully capable of providing consumers with the necessary products For which Russia implements the policy of modernization and reconstruction of the fuel and energy complex. Russia has been one of the leading oil exporters for many years, the main indicators of the oil sector have been examined, the definition of economic security and energy security has been defined. The energy security of Russia is analyzed in the conditions of the crisis, as well as the globalization of the world economy. A brief description of the energy security policy of the Russian Federation is given. An assessment is given of both the world oil sector and the Russian oil sector, based on this assessment, a conclusion has been drawn about the deteriorating conjecture of the oil industry. A correlation-regression analysis of the effect of oil prices on the quotes of the Russian ruble was conducted, and on the basis of the findings it was concluded that the Russian economy is in a sufficiently strong dependence on oil prices. The possible variant of reducing such dependence through the increase in the role of SPIMEX in the international arena and the creation of an oil benchmark in the Russian Federation is considered and described

DescriptionThe article presents the theoretical and experimental research of the guide wire, made of polytetrafluorethylene, for sieve system of air grain cleaning machines. We have calculated trajectory of movements of the components of piles of sunflower seeds in the vertical pneumatic channel when they are vanishing from the surface of the guide wire at its various parameters. Specifying the location of a guide wire polytetrafluorethylene in air-sieve grain cleaning machine was carried out in an experimental setup. The guide wire of polytetrafluorethylene was installed in three locations: 1) at a distance of 20 mm to the pneumatic channel; 2) on the levels with the pneumatic channel; 3) at a distance of 20 mm inside pneumatic channel. The approach of the guide wire into the inside of the pneumatic channel in the experimental setup the quality of sunflower seeds increased with 97.61 to of 99.08 %. The content of organic impurities, milled and broken seeds in the pile decreased respectively from 1.83 to 0.21 %, to 1.29 0.66 % 0.51% to 0.25% in the manufacture of wire made of polytetrafluorethylene. To increase the purity of the seeds of the main culture we use a photoelectron separator, and the received seeds for animal feed were in the form of sunflower cake produced on screw presses. As a result of carried out experimental and theoretical researches it is established, that the guide wire shall be made of polytetrafluorethylene and are placed inside the pneumatic channel at a distance of 20 mm and an angle of 40°, which allows to improve the quality of the seeds material and increase the speed of their input to pneumatic channel air-sieve grain cleaning machines type MVU-1500

THE WORKING CAPITAL OF LLC «ELECTROSVYAZSTROY» AND ITS EFFICIENCY
DescriptionThis article discusses the activities of LLC «Electrosvyazstroy». The authors reviewed brief economic characteristics, the analysis of the motion and structure of working capital, the proposals for improving the efficiency of working capital LLC «Electrosvyazstroy». Not only the main funds, labor and financial resources, but also using inventories ensure production and economic activity of the enterprise. Materials are one of the most important elements of the production cycle of any organization. Currently in a market economy identifies the importance of quality-indicators, among them are such as reducing the unit cost of raw materials and fuel. This requires the integrated use of natural and material resources as much as possible to eliminate losses and irrational costs, is widely involved in the turnover of the secondary resources, as well as other products. The main purpose of working capital – ensuring continuity of the production process. Working capital has a special place in the structure of the enterprise, as they provide strong financial position, creditworthiness, and investment opportunities of a business entity. The policy of working capital management involves two basic questions: what level of working capital is most suitable, and for what account of sources it is possible to finance it

A METHOD OF CALCULATING THE COMBINE PARK IN VARIOUS CONDITIONS OF CLEANING
DescriptionThe article discusses the technique of calculating the combine harvester under various harvesting conditions. The authors consider two options for optimizing the fleet of combines: the first, when the harvested area is set, the second, when the harvested area is not specified. In the first case, the harvester park is calculated for a known area with different harvesting times, but within the boundaries of the agro-industry. In the second variant, a park of harvesters is justified and it is calculated how much space it will be able to clean for a different duration of harvesting operations

THE RATIONALE FOR THE USE OF ELECTROMAGNETIC FIELD IN THE PRODUCTION OF SUNFLOWER OIL
01.00.00 Physical-mathematical sciences
DescriptionIn some works, the feasibility of the use of fixed and variable electromagnetic fields of different frequencies and tension in the production technology of sunflower oil are shown, but there is no theoretical justification. The possibility of electromagnetic effects is associated with the presence of polar molecules specific to organic systems. Without prejudice to the role of polar groups of terrestrial circuits, this work tries to address this challenge more comprehensively. The reason for this is the distinctive feature of the behavior of sunflower during its flowering. This characteristic is that the sunflower hat during the day changes its direction in accordance with the direction of movement of the Sun across the sky; so called "magnetism" of their attraction. To justify this effect, we have analyzed the essence of emitted photons, the Sun chemical composition and structure arrangement of seeds in a sunflower hat. Particles of light from the Sun represent a stream of photons - a wide range of electromagnetic waves of frequencies that exhibit and magnetic properties. The article shows principal macro- and micronutrients of sunflower raw materials and divides them into groups of para- , dia- , and ferromagnetic materials. In sunflower seeds, there are chemical elements: diamagnetism-C, H, N, P, S, B, Cu, Zn, J; paramagnetism-O, K, Ca, Mg, Mo, As and ferromagnetic-iron (Fe). As there is resultant force of the magnetic attraction between the sunflower hat and magnetic flow of photons from the Sun, this effect dominates the action of paramagnetics K2O ( -28.4 24.5%), CaO (7.6-17.0)%, MgO (12.3-17.9%), magnetized in an external magnetic field in the direction of the field. The presence of evident effect demonstrates that it is possible to improve a number of technological operations in the manufacture of sunflower oil using electrical, magnetic or electromagnetic fields

COMPARATIVE CHARACTERISTICS OF TECHNOLOGICAL PARAMETERS OF DELICACIES FROM MEAT OF IMPORTED PIGS
06.00.00 Agricultural sciences
DescriptionIn recent years, many pigs of specialized breeds, characterized by increased meat qualities, have been brought to Russia from Canada and a number of European countries. The article presents the results of the assessment of slaughter and meat qualities of pigs of different genotypes. Danish pig meat was used as research objects: purebred landrace (CHL), benthic hybrid Landrasx yorkshire (LxY), three-breed hybrid landrace hyorkshire x dyurok (LxXxD), removed from control fattening, and developed prototypes of delicacy products. The commission evaluation of meat and broth showed that the boiled meat from the three breed animals received the highest score, and the quality of the broth significantly exceeded the samples of purebred landrace and two-breed animals. As a result of the tasting evaluation of the Voronezh ham, it was established that the samples of meat from threebreeded pigs, in comparison with the samples from purebred meat, show the most pronounced flavor, aroma and soft consistency
