USING RATINGS TO ASSESS THE CREDITWORTHINESS OF BANKS

abstract 1271703022 issue 127 pp. 340 – 352 31.03.2017 ru 399
The article is devoted to the study of rating the creditworthiness of banks. The concept and the process of ranking have been revealed. The authors give a retrospective analysis of the development of views on the formation of ratings in the banking sector. Particular attention is paid to the methodology of Moody's, the largest rating agency, which is based not only on the study of the set of key performance indicators of the company at the micro and the macro level, but also takes into account the quality of company management and current trends in the industry. On the basis of gradation we made a comparative analysis of methods of ratings by Standard and poor's, and Moody's rating agencies, which allows identifying the unity of their approaches to evaluating the creditworthiness of companies. Along with international experience rating, we have studied Russian experience. We have considered the legal basis for the activities of Russian ratings agencies and documents that are the primary source of data for the evaluation of companies. We study ratability particularities in domestic practice; in particular, we have presented criteria for Rating Agency called Expert RA. The authors presented the forecasted values of key indicators of the economy of the Russian Federation, which affect the country's credit rating, such as GDP, inflation rate, the key rate, unemployment rate, exchange rate of the ruble. It was concluded that there was a need to move from quantitative to qualitative assessment when examining the organizational effectiveness of the banking sector

USING REAL-TIME PCR HYBRIDIZATION PROBES, ON THE EXAMPLE, OF A MARKER OF THE TMV RESISTANCE GENE IN A TOMATO CULTURE

abstract 1582004012 issue 158 pp. 168 – 180 30.04.2020 ru 10
The article discusses the method of selection using markers in the selection of parent pairs for hybridization, in the selection process and in the subsequent evaluation of parent lines, used in linear and backcross selection of tomatoes. The work was performed on tomato hybrids that combine resistance genes to tomato mosaic virus (ToMV) or tobacco mosaic virus (TMV) in their genome. The research used seeds of foreign F1 tomato hybrids recommended by the manufacturer as resistant to the tobacco mosaic virus. Most of the tomato hybrids were Dutch selection, such leading firms as De Ruiter Seeds, Enza Zaden, Rijk Zwaan. The aim of the work was to test a system of hybridization probes designed to identify a gene for resistance to the tobacco mosaic virus. The study of the genotype of tomato plants was carried out in the laboratory of molecular diagnostics of plants , equipped with modern devices for PCR analysis on the basis of NIIOZG (Krymsk). Plant material was collected in different phases of plant vegetation. pre-numbered 1.5 ml test tubes (SSI-1200-00), plastic tablets, tweezers, and distilled water were used to collect plant samples. The collected samples were stored in a refrigerator until the plant DNA was isolated. During the study, collectible tomato samples were studied, including 8 F1 hybrids and 2 lines used as controls. According to the results of genetic analysis using the marker of the TMV resistance gene, it was found that all hybrids and one control line # 175/14 have a resistance gene in their genotype, and the analysis also showed the state of the gene – homozygous or heterozygous. The results of artificial infection confirmed the results obtained by PCR analysis. At the same time, using genetic research, it is possible to determine the exact state of the gene in the plant, which cannot be determined by methods of artificial infection, since no visual differences were found between plants with a heterozygous and homozygous state of the gene. The created marker and PCR analysis method can be recommended for wide application in the selection process of tomato culture. As a result of research, it was found that modern tomato hybrids have a gene for resistance to tobacco mosaic virus (TMV) in their genotype. This was determined by genetic analysis and confirmed by a test using artificial infection

USING ROZENBLATT-PARZEN APPROXIMAION FOR RECOVERING A CUMULATIVE DISTRIBUTION FUNCTION OF CONTINUOUS RANDOM VARIABLE WITH A BOUNDED SINGLE-MODE DISTRIBUTION RULE

abstract 0921308076 issue 92 pp. 1127 – 1140 31.10.2013 ru 1210
In this report we have compared an approximation accuracy of distribution function of continuous random variable in a bounded region calculated with Rozenblatt-Parzen method and imaginary sources method. The comparison has been performed with theoretical distribution rule. We have explained the reasonability of using imaginary sources method in case of continuous random variable with single-mode distribution rule

USING SORBENTS IN FEEDING FOR INCREASING ENVIRONMENTAL AND FOOD VALUE OF BROILER MEAT

abstract 1011407167 issue 101 pp. 2508 – 2518 30.09.2014 ru 854
The article presents the results of two researches and production experiments conducted on broiler chickens grown in the area with high technological background in feed heavy metals and at the risk of aflatoxicosis. Experimental data obtained during the first experiment suggests that in order to optimize biology and agro-food value of meat with excess of heavy metals and the risk of aflatoxicosis it is advisable to grow broiler chickens of the domestic cross-country of "Smena -7" In the barley-wheat-sunflower-type animal feed of broiler chickens of this cross one should include the formulation of a mold inhibitor of methoxy - phenyl. During the second research and production experience for broiler chickens of “Smena-7” cross it has been found that with the joint supplements in animal feed to the high background of heavy metals and aflatoxin B1 preparations of beet pectin and methoxy - phenyl having absorption properties, there is an increase of slaughter and meat qualities. At the same time, the meat of poultry has increased its protein-quality score and decreased the concentration of heavy metals in the meat , which helps to improve consumer properties of poultry products

USING TECHNOLOGIES OF EXPERT SYSTEMS FOR SECURITY IN INFORMATION SYSTEMS

abstract 1101506119 issue 110 pp. 1818 – 1825 30.06.2015 ru 609
The article is devoted to the expert systems technology using to monitor the correct operation of the software and databases. It is noted that the main issues of security management in critical information systems is a process of observation and collection of information in a computing environment. Observation results should be evaluated and processed by an expert on security and then recorded in the database of expert systems. One of the possible options for security management of distributed computing network - creating a security machine. It will ensure: minimum response time to external perturbations; the accuracy of the audit protected by S-interface and independent decision-making process of the state of the controlled elements of information systems. After that, the agent is completely worn out; it is destroyed and replaced by a new one. This aging mechanism protects agent from analyzing and from external attacks
