The problem definition is executed and ways of improvement of a control sys-tem by university and market policy are offered. Re-sults of the analysis of external impacts on an university as social and economic system, the maintenance of an exit of system, relationships of cause and effect of an exit and a system entrance are given
The article covers the basics of reproduction industry based on regional and industry characteristics (for example, the coal industry of the Rostov region). We have also considered the current status of coal mining enterprises and defined their role in the regional economy. We have examined and detailed the three main phases of the concept of long-term program of development of the coal industry till 2030. We have analyzed the first steps of its implementation, which had been not as successful as expected. We have also defined the measures to stabilize the coal industry for the coming year and developed areas of scientific, technical and innovation policy for the further development and promotion of the world market for coal products
The existing settlement modes of loading of wheels of cars are defined for the conditions which are closest to road service conditions and are reflected in the existing standards. However these standards can't be applied to an assessment of functional qualities of systems of cushioning the cars which are operated in the conditions of agricultural production. The small step of roughnesses, change the cushioned characteristics under the influence of operational factors lead to emergence of the off-design modes of the movement. The purpose of the work was the research of loading of wheels of the car when moving on mulch of grains. For the purpose of obtaining characteristics of the roughnesses influencing car wheels we have recorded a smoothed microprofile of the field and got the statistics, rated autocorrelated function, spectral density of influence of a microprofile. For carrying out the researches the known mathematical model of a car road system was accepted. Influence of speed of the movement, normal rigidity of springs and tires, coefficients of damping of a suspension bracket and tires on vertical fluctuations and loading of wheels of forward and back axes of the car is investigated. The executed researches showed that the movement of the car is followed by fluctuations of indicators of loading of running system with obviously expressed periodic components. The change of the coefficient of damping of a passive suspension bracket and tires in possible limits has no essential impact on loading of wheels. Values of normal roughness of springs of forward and back axes of the car, normal rigidity of tires at which dynamic load of wheels of the car is minimum are established
We consider the economic essence and general rules of the reproductive process in dairy cattle breeding. We have analyzed a modern condition of subsector: change in the numbers of livestock, breed and numerical structure of evaluation dates cattle, the volume of generation of raw milk, the profitability of its production and realization. We have also analyzed the balance of resources and use of milk, level of consumption and dynamics of imports dairy products in Russia. Reduction of volumes of raw milk has resulted into a deficiency of food of its own production, an increase in of import deliveries of milk and of dairy products. As a result of the conducted research we revealed some tendencies, that have a negative impact on the reproductive processes of in dairy cattle breeding: a long period of reproduction, disparity of prices on milk and the products industrial organizations, the destruction of permanent integration ties, high degree of deterioration of the equipment, strengthening of the process technological degradation, non-observance of technology of feeding and livestock, poor use of the genetic potential of animals, monopoly processing and trade organizations, weak susceptibility subsector to innovative technologies. Perfection of reproductive process in the subsector assumes growth of solvency of economic subjects at the expense of reduce the level of disparity in prices, optimization of interbranch of mutual relations, development of cooperation and of agroindustrial integration
The phase transition for US(3) gauge field (without quarks) is considered. It is shown that the phase transition is due to the fact that at high temperatures the partition function should be calculated as for a gas of gluons, whereas at low temperatures as the sum over energy levels of correlated quantum states of SU(3) gauge field. A correlated quantum state for strongly interacting fields is defined as a nonperturbative quantum state of strongly interacting fields. The energy spectrum of these quantum states are discrete one. A lower bound of the phase transition temperature by comparing of the average energy for the perturbative and nonperturbative regimes is estimated (for glueball being in thermal equilibrium with the thermostat). It is shown that this quantity is associated with a mass gap. In a scalar model of glueball its energy is calculated. It is shown that this energy is the mass gap. If we set the glueball mass ~ 1.5•10³MeV then it is found that the corresponding value of coupling constant lies in the nonperturbative region
The article submits a mathematical dynamic model of varying pressure of the steam, depending on fuel supplying in the boilers
We have special demands to the planting of the tilled crops. Unlike grain crops, the tilled crops are sowed in a line with the certain step, which permits to provide the rational placing of the plants on the feeding areas. Due to this, the necessary conditions were made for their further growth and getting of big crops. For planting of the tilled crops all over the world people apply pneumatic precision drills with vacuum seed-sowing mechanisms and the quality of realization of the operation depends on their work greatly. The process of work of the vacuum seed-sowing mechanism can be divided on basic stage, the process of catching a single seed and carrying it out of the layer of the others with the drawing hole is the most responsible among them. The analyses of the work which has been done let conclude that the influence of the agitator on the layer of the seeds in the zone of their catching with the drawing holes increases the efficiency of this process. With an aim of the activation of the working process of the central agitator the authors offer to make its blades in such a way that their working sides would be turned in the direction of rotation of the agitator and the plane of the feed disk. All this let use the agitator not only for activation of the layer of seeds but for their push to the drawing holes of the feed disk. The proof of the offered construction is presented in the article, the results of the comparative experimental researches of the serial and the modernized vacuum seed-sowing mechanisms and the analyses of obtained data are shown, conclusions have been formulated
Черешки листьев, взятых из растений ин витро, девяти межвидовых гибридов винограда: подвоев Берландиери х Рипариа ‘Кобер 5ББ’, Рипариа х Рупестрис ‘101-14’ и сортов (cvs): 'Бианка', 'Зигфридребе', 'Подарок Магарача’, ‘Первенец Магарача’, ‘Цитронный Магарача’, ‘Интервитис Магарача’ и гибридной формы ‘Магарач 100-74-1-5' культивировали на твердой среде NN, содержащей различные концентрации 2,4-D и BА в различных сочетаниях. Для того, чтобы инициировать рост клеточных суспензий, проэмбриогенные каллусы пересаживали в жидкую среду NN, дополненную 1.0 мг/л 2,4-Д и 0,2 мг/л BА. Субкультивирование этих суспензий в жидкую среду NN, дополненную 2 мг/л NAA и 0,1 мг/л BА, привело к развитию агрегатов эмбриоидов, а пересадка в жидкую среду с 0,5 мг/л BА вызвала развитие единичных глобулярных и сердцевидных эмбриоидов. Проэмбриогенные клеточные суспензии, состоящие из преимущественно отдельных клеток, могут быть использованы в трансформации генов и селекции на клеточном уровне с целью уменьшения вероятности появления химерных растений
