06.00.00 Agricultural sciences
DescriptionHigh growth-rate of plantlet is the integral index of intensity of physiological processes at rice and other cultures. 20 typical plantlets from each of two variants were studded (in the distilled water in thermostat at a temperature 29° C) by: length of embryonic root and coleoptile. Comparative analysis of trait characterizing the growth rates of rice varieties showed reliable advantage of Russian ones above the Italian and Chinese. Local varieties, regionalized until the year 2000, exceed new ones on this trait. Highest growth rates were characterized by medium grain samples. The white grain and red grain varieties are excelled other groups on the height of plantlet. Analysis rates of height of plantlets in the distinguished groups showed the necessity of prosecution of improvement of the above enumerated signs at the varieties of late term of ripening, long grain, with Waxy gene, colored grain. We recommend to sow this type of varieties on fields with good leveling, because of low speed of growth

DescriptionProductivity of seeds of cereal crops essentially depends on the quality of the seed grain, which is being defined both by biological condition of seeds and technologies and technical resources, which are being used in, machine processing of seed heap. In this connection, different injuries of weevils which are occurred while mechanical and thermomechanical influences from tools of machines and aggregates have got vital importance. Apart from the breaches of integrity of the weevil’s cover there are also exist traumatizing changes of its inside structures which are frequently covered with casings and do not being viewed with visual inspection. Conditions of inside structures of weevils were researched with radiographic method and also were defined possible types of traumatizing changes which depend on mechanical and thermomechanical influences, which were eliminated in universal classification of injures among the inside structures of seeds of agricultural cultures. Also, wу have analyzed the influence of chosen types of injuries on seeds’ sowing qualities and found that all injures of weevils essentially and differentially influenced the sowing and fruitful qualities and should be considered while choosing the technological schemes of preparation, working tools and while tuning the aggregates’ regime of work attached to the machine processing of grain and seed heap

SIMULATION OF PARTICLE DYNAMICS IN THE STERN-GERLACH APPARATUS
01.00.00 Physical-mathematical sciences
DescriptionThe model of the motion of particles in the SternGerlach apparatus in the classical and quantum mechanics was developed. The data simulation of particle trajectories and distribution of silver atoms on the surface of the plate in their deposition are discussed. It was found that for the experimentally observed distribution of two-dimensional shapes of the atoms must be assumed that the atoms are not involved in the precession motion in a magnetic field, while maintaining the direction of the magnetic moment, for example, parallel to the induction vector of the magnetic field during the time of motion in the apparatus. To obtain a realistic picture of the figure of the scattering of atoms used a classical model of movement and expression of forces compatible with the quantum picture of the motion of particles with spin ½. The magnetic field is simulated based on the original Stern-Gerlach data describing the distribution of the gradient of the induction components related to the splitting of the beam. Quantum model of particle motion is based on the Pauli equation in the boundary layer approximation. It is found that in this model, depending on the initial polarization of the particle, beam is split into either two or is deflected towards the magnet blade or in the opposite direction. It is shown that if the initial conditions for the task are reproducing the geometric dimensions and the magnetic field in the Stern-Gerlach apparatus, the figure of the scattering particles in the shape of the outline is similar to the experimentally observed shape

Description
The problem of drug addiction in the Russian Federation poses a threat to the national security. For effective decision-making in the field of drug prevention and fight against drugs, it is necessary to assess the drug situation, the state of law enforcement practices and socio-economic development of the observed areas. The article describes the method of complex statistical evaluation of the level of drug addiction in the Russian Federation. Based on a systemic approach author distinguishes stages of multivariate statistical analysis of a priori indicators characterizing the state of socio-economic, demographic, biomedical and law enforcement situation in certain areas of the federal districts of the Russian Federation. The classification of signs into factorial indicators groups is proposed. Estimations of relationships studied statistics and draw conclusions about the impact on the drug situation of various factors, including the average for the group, are presented. Then this paper describes the application of the factor analysis to construct regression models to predict the drug situation in the Russian Federation according to the status of independent indicators and trends in the integrated development of regions. A method for evaluating the level of development of the drug situation in the Russian Federation because of automatic classification algorithms is proposed and the principle of its application is proven. The results of the classification of the federal districts of the Russian Federation on the level of the drug situation are given

MATHEMATICAL MODEL AND FIELD RESEARCH OF FUEL WOOD NATURAL DRYING IN BUNCHES IN THE CUTTING AREA
DescriptionThe purpose of this research is to receive mathematical model of natural drying of the whole trees in bunches in a cutting area based on experimental data. The field research of natural drying from March to October 2015 of the whole trees of pine and birch of different diameter laid definitely in bunches in a cutting area was conducted for this purpose. The mathematical model describing change of moisture content in wood in the course of natural drying in bunches in a cutting area was as a result developed. The received equation of regression defines dependence of average humidity of wood in a bunch from diameter of wood, quantity of a liquid atmospheric precipitation, relative humidity and temperature of air, average speed of the movement of the air blowing in bunch of trees, duration of natural drying. The developed mathematical model allows predicting change of moisture content of wood in the course of natural drying with a margin error less than 5%. Humidity of wood in the course of natural drying from March to October was on average reduced from 52% to 27%. Besides, in article the technology of logging of fuel wood on an energy forest is offered. The technology of stacking of trees in bunches at logging of the fuel wood which is grown up in forest plantations is offered. The results of the research can be used for increase of production efficiency of fuel wood

THE PERSPECTIVES OF LOMBARD BUSINESS FORMATION AND DEVELOPMENT
DescriptionThis article discusses trends in the development of the Lombard business as one of the dominant components of the service sphere. A brief history of pawnshops and their formation is described. The causes of high demand for Lombard services are commented on. Regarding the situation of pawnshops in the market the views of the large pawnshops chains owners: “Vash Lombard” (“Your pawnshop”), “Obyedinenniy Lombard” (“United Lombard”), Stolichniy” (“Capital”). The benefits of pawn business compared with the banking service are given. The current problems of sustainable development of Lombard businesses are shown. We present difficulties in the process of drawing up and submission of reports, as well as quick adaptation to changes in legislation as one of them. Lombard structure allowing determination of this business running specificity is considered as one of the main aspects of the subject study. One of the subsequently formed properties – pawn shops high quality security systems, which in many respects determines their stability in the market is also noted. The development trends of this business, which will strengthen their position, are mentioned. In conclusion, a brief justification of the reasons for the precarious state of business in the country is given as a whole; however, presupposition is made of the eternal relevance (inelasticity of demand) of Lombard services

Description
In the article, we give the characteristics of the Russian meat cattle breeding as one of major factors of efficiency of domestic agriculture. Dynamics of a livestock of cattle in certain regions, number of breeding farms, which are engaged in cultivation of cattle of meat breeds, were presented; we also revealed a tendency of their increase. Dependence of shortage of breeding resources of the most competitive specialized meat breeds and the volume of import of cattle are revealed. The main problems, which accompany functioning of the branch of meat cattle breeding, are defined. The average mass of carcass of cattle on slaughter is specified in the different countries of the world. Based on the calculations, the conclusions are drawn and the forecasts for domestic agricultural producers proceeding from the developed market dynamics are defined. Reference points of the state support of branch for which solution of problems the Ministry of Agriculture developed the State program of measures of the state support of development of meat cattle breeding which has to provide a gain of a livestock of meat breeds by 2020 are specified. Considering prospects and possible risks of development of domestic subsector of meat cattle breeding, we specified a need of such development of the branch; it has to be based, first of all, on implementation of large-scale projects on the basis of the competitive meat breeds of world level and the low-used resources of pasturable cattle breeding which are available in Russia. It will allow realizing fully the least expensive intensive and pasturable production technology of high-quality beef.
