STOCHASTIC DYNAMICS OF PRICES IN A MODEL OF FINANCIAL MARKET WITH DIFFERENT TYPES OF NOISE TRADERS
DescriptionIn the present study, the calculations of price dynamics are made in the model of a financial market consisting of fundamentalist and noise traders. Numerical calculations are carried out in accordance with the full Walrasian dynamic price adjustment rule. To describe fluctuations in the number of optimistic and pessimistic noise traders, a seminal stochastic Kirman’s ant model (reducible to a Markov chain) is used, as well as its modification with different scaling properties of the parameter controlling the strength of herding behavior of noise agents

Description
The article presents the results of three years of researches conducted at the Department of Viticulture of Kuban State Agrarian University, to study the processes of shoots and rooting of the three-bud cuttings of grapes of Pervenets Magaracha, Podarok Magaracha and Cytrony Magaracha of the selection of Magarach Institute of Grape and Wine. The area of these varieties, which are inter-specific hybrids, in the Krasnodar region is more than 2 thousands hectares. The cuttings were rooted in sawdust in a greenhouse on a heated rack. It was found, that the regenerative capacity of cuttings was strongly dependent on the method of their storage prior to installation on the germination. The best results were obtained in the case when cuttings had been stored in the refrigerator before starting the experiment. The lowest impact of the way to store cuttings was on the percentage of cuttings with blossoming eyes, and the largest - the length of the shoots, the output of the cuttings with at least 3 of the roots, and the average number of roots developed on one cutting. Rooting of cuttings and their growth with three and more roots were different over the years for the varieties of Pervenets Magaracha and Cytrony Magaracha, in favor of one sort or another, but the average 3-year difference between varieties was not significant. On average, in two or three years, the maximum number of roots appeared in the variety of Cytrony Magaracha, which was a bit ahead of Pervenets Magaracha. The difference in the number of cuttings formed at the roots was authentic. Correlation analysis showed that the closest relationship to the performance of the rooting ability of cuttings was found in the length of the shoots. The level and the nature of the identified correlations suggests that the rooting ability of the cuttings of the varieties of Pervenets Magaracha was determined primarily by hormonal activity, Podarok Magaracha by its supply of plastic substances, and Cytrony Magaracha had equally both factors

MODERN QUESTIONS OF POTATO HARVESTING EQUIPMENT PERFECTION
DescriptionPotato is cultivated in 130 countries on an area of over 18 million hectares; it annually gives more than 300 million tons of tubers. The share of the Russian Federation accounts is about 11% ... 14% of total production. The resulting potatoes consumed in food, animal feed, technical purposes, seed fund. According to the Ministry of agriculture of Russia, the largest number of potatoes in our country (89 %) is produced in peasant farms and personal farms of citizens, the area of cultivation of which make up about 2.7 million hectares. At such farms for the harvest, they use mainly potatodiggers, followed by selection of crops manually. The use of diggers in small areas of planting is more costefficiently in relation to the harvesting combine. In addition, the parameters requested for ATT to damage potatoes when harvesting with the diggers (3%) are higher than during harvesting by combine harvester (5%). As practice shows, for the use of cleaning units, even under optimal harvesting conditions in the hopper of the combine, there are soil and vegetable impurities. There are many different devices intended to localize the problem. Based on the foregoing, we can conclude that it is necessary to pay considerable attention to the quality of work of excavating working bodies, because it affects the productivity of the functioning of the whole machine. Currently, there are widespread potato aggregates with the receiving part, equipped with side disks, spaced along the edges of the plowshares. The disks cut off the raised layer of soil from between the rows. This entails improving the performance of the potato harvester. The most efficient and economical from the point of view of energy consumption, is the work of passive disks with hooks. The quality of potato harvesters depends on the design and performance of excavating bodies. The proposed design solution for an excavating body increases the productivity of harvesting machines

01.00.00 Physical-mathematical sciences
DescriptionMicro and nanofluidics are the new multidisciplinary sciences. One of the tasks of which is creation and management of flow of fluid in the thin channels size of a few nano- or micrometer which exposed the external electric field, where the walls are the ion exchange membrane. Electroosmosis (electroconvection) plays an important role in these tasks. A large number of articless were devoted to electroosmosis. One of the first, Dukhin S.S., Mishchuk N.A. and Rubinstein I. gave a theoretical explanation of the overlimiting current by electroosmosis. They used two-dimensional Stokes equation to calculate the flow of the electrolyte, and one-dimensional equations of Nernst-Planck and Poisson to calculate the electric power. These researches have multiple limitations because of the computational complexity the mathematical simulation. Thus, there is an actual problem of the asymptotic solution of boundary value problems for the two-dimensional systems of equations of NernstPlanck and Poisson without these restrictions. These researches we derived in simplified models of electroosmosis in galvanic dynamical mode using the decomposition method. We have created a hierarchical system of two-dimensional mathematical models of ion transport of salt and electroosmosis in micro- and nanochannels formed by selective ion-exchange membranes

TENDENCIES OF THE DEVELOPMENT OF THE BANKING SECTOR AND THE INTERBANK COMPETITION IN RUSSIA
DescriptionThe modern banking system is one of the most important and integral structures of market economy that is on a threshold of high-quality changes and owing to what the competition in the market of banking services increases. Relevance of this subject is caused by the need of definition of current trends of development of the interbank competition in Russia. In the article, the general dynamics of number of the operating banks of Russia for the last 8 years is analyzed and conclusions that the essential number of banks is concentrated in the European part of the country, and a small amount of regional banks beyond the Urals are drawn. It is revealed that the main criteria influencing a choice of bank the natural person are: the term of existence of bank in the market, availability of ATMs, favorable rates on deposits and the credits. Factors of the interbank competition are analyzed and basic methods of realization of competitive strategy of banks are presented. The main reasons for insufficient development of the banking sector of Russia are defined: opacity and high concentration of a banking system, macroeconomic instability, low capitalization, institutional problems, etc. Recommendations for strengthening of competitive advantages of domestic banks are offered: development of new financial services, association with other banks and participation of banks in the organization of projects together with the enterprises which business can be considered the most interesting and perspective

06.00.00 Agricultural sciences
DescriptionThe article discusses the various technologies of cultivation of winter barley at two ways of main tillage (recommended and zero-level) with different backgrounds of soil fertility, fertilization rates, protection from weeds, pests and diseases. Consistent improvement of soil fertility and other fertilizers resulted in an increase in crop productivity. Nutrition is the basis of life of a living organism, including plants. The value of crop yield and its chemical composition depend on the conditions of nutrition. It is achieved with the optimum combination of light, heat, air, water, food, etc. In this connection, in the development of methods of cultivation of this crop, we may not only increase the yield of grain, but also pay due attention to the quality of cultivated products. Thus, studies in the experiment showed that the intensification of cultivation technology of one phenomenon substantially and significantly affects the productivity of the given culture

APPROBATION OF MULTIPLEX SSRANALYSIS FOR DNA-FINGERPRINTS OF RICE VARIETIES
DescriptionResults of testing of multiplex sets SSR-markers for genotyping of rice varieties are presented in the article. Two sets of SSR-markers were formed: 1: RM1+ RM11+ RM70+RM122; 2: RM164+RM167+RM168. The optimal combination of DNA markers in the multiplex sets and PCR conditions allowed obtaining accurate, easily interpretable results when performing fragment analysis on automated genetic analyzer ABIprism3130. Using multiplex sets, genotyping was performed for several varieties of rice: domestic breeding and one variety – IR36 from the breeding of IRRI (Manila, Philippines). For all the studied varieties specific SSR-fingerprints were obtained. RM 168 marker showed in domestic varieties a low level of polymorphism - one allele of 97 bp. However, at the same time, the variety IR-36, showed a second type of allele 107 bp. In addition, the loci of RM1, RM11, RM167 and RM164 have unique alleles in this variety. It is consistent with significant genetic differences of these varieties and the rest of the varieties in studied sample. The proposed SSR multiplexes are promising for use in DNA certification of rice varieties and assessment of genetic diversity
