PREDICTIVE EVALUATION OF THE EXPECTED RICE YIELD IN THE KUBAN REGION IN 2016-2020

abstract 1201606083 issue 120 pp. 1250 – 1265 30.06.2016 ru 574
The article presents the analysis of variation of daily mean temperatures for the period 1977-2015. Clear tendency for their increasing in pre-sowing and especially in growing period is found. Heat supply of separate months in pre-sowing period increased in the row: April-February-January-December-March, and that of growing period – in a row: May-Juny-JulySeptember-August. Presence of slight correlation (from -0,256 to 0,268) of temperatures in winter-spring months with heat supply of coming spring summer months is found. It is shown that correlation of rice yield with temperatures of pre-sowing (DecemberApril) and growing (May-September) periods varies from weak to average (from 0,016 to 0,524) with a tendency to increasing from winter months to summer ones. Use of analog method made it possible to estimate roughly the nature of t upcoming growing season of rice in the current 2016: after the abnormally warm winter one should expect the value of heat supply of summer months to be close to normal. In the physiological sense, such distribution of summer temperatures is favorable for rice. Use of one of the most effective forecast methods – smoothing the time series (method of «moving decades») – made it possible to evaluate medium-term rhythms of heat supply of rice growing season and yields. It was found that after an abnormally high level of heat supply of the growing season, marked during last decade, we should expect a decrease in spring and summer temperatures - the next attack of the "cold" cycle. If this hypothesis is confirmed, then up to 2020, and later a natural tendency for decrease in rice yields, arising from the adverse factors of temperature, will continue which should also affect the economic efficiency of the industry as a whole

INVESTIGATION OF NOISE AND VIBRATION OF CUTTING CIRCULAR SAWS

abstract 1221608026 issue 122 pp. 357 – 365 31.10.2016 ru 574
The article presents the results of theoretical studies of noise cutting circular sawing machines. Practical calculation of the noise spectra is based on the determination of the dependency of the sound pressure of the noise sources of the object of study. In the sound system, circular sawing machines sound energy is emitted by the following sources: disc cutter and the mandrel. Therefore, the dominant noise sources should be allocated to the technological subsystem "tool – mandrel” with a bit less rigidity than the carrier system of the machine and directly receives the cutting forces when milling. Thus, it is possible to reduce sound pressure levels in almost two ways: by increasing absorption production facilities and (or) decrease in sound pressure of the noise source. In this work, we have justified the second way – reduction of the intensity of acoustic radiation of the source

ASSESSMENT OF SMALL BUSINESSES DEVELOPMENT IN THE KRASNODAR REGION AND PROBLEMS OF THEIR FUNCTIONING AND MANAGEMENT

abstract 1221608081 issue 122 pp. 1216 – 1231 31.10.2016 ru 574
Small businesses play a special role in the development of the state economy: the national budget from taxes, increasing the welfare of the population, the question of employment, the formation of competitive environment, cost containment and improving the quality of goods and services. In this regard, become topical issues related to the creation of favorable conditions for the functioning and development of management tools and mechanisms of development of organizations of this segment of the economy. This work aims to identify the key problems of functioning of small business organizations through the assessment of the development of this segment in the economy of the Krasnodar region. For the evaluation of small business development in the Krasnodar region we used basic unit of economic analysis aimed at determining the major trends of change in number of organizations average number of employees, revenues, as well as a number of relative indicators in the whole segment and by major activities. It was determined that the number of small businesses in the Krasnodar region for three years practically did not change, whereas a decrease in the number of workers employed in this segment, revenue has a small tendency to increase. In the structure of the segment is dominated by micro-enterprises, 47% operate in the trade sector. Indicators of development of small business organizations meet the classification criteria in terms of revenue for microenterprises and their share in total number of companies this segment is 1%. The results of the study say the lack of a clear strategy from small businesses, due to unavailability of tools for its development, expressed the high value of the resource and, as a consequence, ignoring this question when organizing the activities of enterprises. Therefore, the question becomes more urgent the development of tools of business modeling and strategic planning adapted to the requirements of this segment

RESULTS OF TEN YEARS BREEDING WORK ON DEVELOPING TOMATO VARIETIES AND F1 HYBRIDS FOR GROWING IN THE OPEN FIELD IN THE KUBAN REGION

abstract 1241610043 issue 124 pp. 684 – 694 30.12.2016 ru 574
Tomato is one of the most popular vegetables in Kuban. Every year, the area under this crop in the region occupies more than 11 thousand ha. Currently the State Register of Breeding Achievements approved for use in Krasnodar region, includes more than 90 tomato varieties and hybrids, however, the need for new, more productive varieties is not reduced. The important task of breeding is development of varieties and F1 hybrids with stable realization of the potential, with high level of yield ability, resistance to adverse environmental factors. In the southern regions of Russia for tomatoes, especially during flowering and fruit ripening, the most unfavorable abiotic environmental factors are excessive heat (air temperature 35 - 45 ° C or higher) and high solar radiation. Adverse temperature conditions often act as a deterrent in obtaining high yields, due to the flowers and fruits drop. The article presents the results of breeding activities of the last ten years (2007 - 2016) on development of new tomato varieties and F1 hybrids for different purposes As a result of studies there were developed four tomato varieties and one F1 hybrid that meet the requirements of production and are adapted to abiotic conditions of cultivation in open field in Kuban

MATHEMATICAL EQUATIONS ANALYSIS OF ACOUSTIC AND ELECTROMAGNETIC FIELDS ARE CREATED BY ACOUSTIC MAGNETIC DEVICE AND DETERMINATION OF SIMILARITY CRITERIA FOR THE CREATION OF NEW CONSTRUCTIONS OF ACOUSTIC MAGNETIC DEVICES DESIGNED FOR USE IN HYDROPONIC SYSTEMS

abstract 1171603031 issue 117 pp. 500 – 527 31.03.2016 ru 575
Conditions in which the work of acoustic magnetic device proceeds are complicated because of the number of interconnections. Solving problems under such conditions analytically is difficult because of many variables and complexity of some dependencies. The article describes the conditions in which the work of acoustic magnetic device, designed for nonchemical treatment of hydroponic solution, takes place. The criteria, establishing the initial state of the chains, containing mutual inductance, are analyzed. The work establishes the criteria relating the physical parameters of the environment with the output parameters of the device. The similarity of conditions of heat transfer on the surface of the device is provided, and the relation of the scale of temperature and power lost when heating the ferrite and winding machine is determined. The criterion of the heat transfer process is defined. The criterion, determining the relation of the environment temperature to the thermal mode of the acoustic magnetic device, is defined. The criterion of the conditions at the boundaries of the system and cavitating liquid is determined. It is found, that the cavitation area appears in the technological volume of liquid at the work of acoustic magnetic device. The criterial equation for geometric parameters of different types and constructions of the acoustic magnetic device is defined. In accordance with the task based on the third theorem of similarity, the group of criteria that provides the similarity of the model to the proposed original by all existing indicators, is selected
