ABC & XYZ – ANALYSIS OF ASSORTMENT OF ENTERPRISES OF BAKERY INDUSTRIES OF CONSUMER COOPERATIVES
Description
To develop detailed and effective business model of bakery enterprises of consumer cooperation it is necessary to have knowledge on strategic goods displayed on a busy segment of the market, not only in volumetric terms, but in the parameters that characterize the stability of sales or consumption. The particular relevance of this study reveals in modern conditions of functioning. The outcome of the baking enterprises of consumer cooperatives is more than 760 tons per day, distributed between 41 baking enterprise producing more than 300 kinds of products. Of course, the information on quantitative and qualitative characteristics of the strategic positions of the range will be a key in making managerial decisions about the production of the program, resourcing, turnover, etc. To solve the problem we have chosen the method of ABC - and XYZ-analysis of assortment of production, based on the criteria of ease of use and breadth of the resulting information. As a result of the application of the methods of ABC and XYZ-analysis and combining the obtained results, we present a classification of the range of the baking enterprises of consumer cooperation product based on the criteria of the contribution of commodity positions in revenue and stability of sales

Description
The organization of animal feeding in the summer and procurement of fodder for the winter are of great importance. The sowings of sugar sorghum can become a reliable and stable source of fodder even in the regions with insufficient humidity. It is a unique drought tolerant crop, which can be used as green mass, hay, silage, grain, mono fodder, briquettes. The article gives the study results of green mass and absolutely dry substance, and the assessment of cultivation efficiency of such sugar sorghum varieties and hybrids grown in FSBSI ‘I.G. Kalinenko ARRIGC’ as ‘Zernogradsky yantar’, ‘Debyut’, ‘Listvenit’, ‘Zersil F1’, ‘Elisey F1’. The productivity of green mass and dry substance of the new variety ‘Listvenit’ and the hybrid ‘Elisey’ exceeded the standard variety on 7,0-5,0 t/ha and 2,30-0,74 t/ha respectively.

Description
Grain is of strategic importance and is the basis for food security. The gross national product share of grain and its products is about 10-15%. It always stands out from other types of raw materials, as it is used to produce the most popular daily foods. According to the characteristics of management in agriculture, it should be emphasized that the absence of objective and timely information at all stages of production of the plant-breeding, and as a result, non-optimal choice of technology of cultivation of agricultural crops, might result in the fact that the cost of labor and material resources increases significantly, the company does not receive profits, and sometimes suffers losses. When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the process of adaptation and the possibility of using the model and the method of binary matrices to solve the problem of the choice for cropping technology

MODERN QUESTIONS OF POTATO HARVESTING EQUIPMENT PERFECTION
Description
Potato 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

APPROBATION OF MULTIPLEX SSRANALYSIS FOR DNA-FINGERPRINTS OF RICE VARIETIES
Description
Results 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

INTERCONNECTION LIMIT THEOREMS AND MONTE-CARLO METHOD
01.00.00 Physical-mathematical sciences
Description
The purpose of mathematical statistics is development of methods for the data analysis intended to solve applied problems. Over time, approaches to the development of data analysis methods have changed. A hundred years ago, it was assumed, that the distributions of the data have a certain type, for example, they are normal distributions, and on that assumption they developed a statistical theory. The next stage, in the first place in theoretical studies there are limit theorems. By "small sample" we mean a sample, which can not be applied to conclusions based on the limit theorems. In each statistical problem there is a need to divide the final sample sizes into two classes - those for which you can apply the limit theorems, and those for which you can not do it because of the risk of incorrect conclusions. To solve this problem we often used the Monte Carlo method. More complex problems arise when studying the effect on the properties of statistical procedures for data analysis of various deviations from the original assumptions. To study such impact, we often used the Monte Carlo method as well. The basic (and not solved in a general way) problem of the study of the stability of the findings in the presence of deviations from the parametric families of distributions is the problem of choosing some distributions for using in modeling. We consider some examples of application of the Monte Carlo method, relating to the activities of our research team. We have also formulated basic unsolved problems

BIOHUMATE EFFECTS ON SOIL BIOTA
Description
The article represents the results of the experiment on biohumate «Vermistar» (which was obtained by vermiculturing) and its effects on mycological soil composition. Humic preparations are interesting in the way of detoxication of soil. When humic compounds are active, herbicides and pesticide decompose faster and concentrations of heavy metals are lowered. Adding humic fertilizers affect the physical properties of water-Soil: increases capillary and light soil field capacity (an average of 20-30%) and heavy water permeability, improves the structure and its water stability, reduced soil density. It was noted, that low doses of humic fertilizer contributes to water-stable aggregates, and high - change the ratio of the structural units in favor of agronomically valuable fractions. This, in turn, is accompanied by changes in the humus state, and biological characteristics of the soil. Moreover, increased microbial activity was observed in the first year of application of fertilizers and as an aftereffect. The maximum total number of microorganisms established in the initial phases of plant development. The increase in the number of microorganisms is enhanced and the enzymatic activity of the soil which in turn increases the mobility of soil nutrients
