CALCULATION OF THE UNSTEADY WATER LINE IN THE KRASNODAR SUBURBAN CHANNEL FOR WATER MEASUREMENT
DescriptionLow level of water accounting and poor control in water distribution in the irrigation system are the main negative factors of industrial influence on irrigated natural complexes. Complex ecosystem way to control water resources involves qualitative improvement and optimization of all parts and elements of irrigation system, from the headwater pool, main channels to local water distribution channels. In this regard, when engineering, constructing, using some new and reconstructed old irrigated systems, the most important problems are the optimization of water use from natural water resources, development and use of highly efficient water-saving and energy-saving technologies of water distribution and water use in the irrigation system. The problem of economical and efficient consumption of water resources on the studied water complex cannot be solved successfully without any related consideration of water accounting and water consumption questions based on system principles. System principles are supposed to collect, analyze and use the information, with the help of complex technical means, which are used for water measurement in conditions of water charges, and for the purpose to control the technological processes of water supply and water drainage, when the needs of water users are satisfied and the environment get less damage. In the work, we study the mathematical calculation of the unsteady water line in the Krasnodar suburban channel for water measurement. The imitated research of hydraulic processes were carried out on the mathematical model of water measurement, based on the characteristic methods, with the use of analytical solution of ordinary differential equations of the initial characteristics. The use of the considered method of water measurement in irrigation channels with the use of analytical solution of ordinary differential equations of initial characteristics will allow to optimize the processes of water measurement and to minimize idle and non-technological discharges of water from the system

CONTROL OF MEDIUM MOVEMENTS OF ULTRA PRECISE DC ELECTRIC DRIVE WITH ELASTIC SHAFTING
DescriptionControl of the movement and positioning are the most intensive tasks of automatic control and regulation. However, these problems must be solved in the automation objects such as assembly and production lines, manufacturing machines, conveyors, hoisting machines, packaging machines, filling lines for liquids, metal-working machines. One problem lies in the fact that all the real drives are connected to the actuators with not perfectly tough shafting, but has some elasticity. This leads to the difficulty of motion of the executive body of the drive automatic control systems which consists of signal source generating signal due optimum speed diagrams for medium movements of electric drive’s actuating device and automatic regulation system, which allows to work out optimum speed diagrams for medium movements of electric drive’s actuating device with ultra-precision. In this article were developed optimum speed diagram for medium movements of ultra-precise electric drive with elastic shafting. Were identified all parameters of diagrams and its range of existence. Also developed device for generating the optimum speed diagram for medium movements of ultra-precise electric drive with elastic shafting. Implementation of the proposed hardware software complex will significantly improve the accuracy of motion actuators of various ultra- precise DC drives

DescriptionBased on the analysis of the nature of some flowering test crosses which have been resulted in the hybridization with purposely chosen sterile sources (analyzers), the new self - pollinated lines of maize have been identified according to the content of fertility-restorer genes of ‘C’ type of CMS. Genotype of the line RD 257 - rf4rf4rf5rf5Ff6Rf6 (class II), genotype of the line RD 245 - rf4 rf4 Rf5 Rf5 rf6 rf6 (class III), genotype of the line RD 274 - rf4rf4Rf5Rf5Rf6Rf6 (class V), genotype of the line RD 231 - Rf4Rf4rf5rf5Rf6Rf6 (class VI ) genotype of the line RD 261 - Rf4Rf4Rf5Rf5Rf6Rf6 (class VII). The identification of the content of the alleles of fertility - restorer genes allows forecasting the nature of flowering hybrid progeny resulted in the hybridization with a known genotype. We have created a catalog of self - pollinated lines of maize according to the fertilityrestorer genes, which consists of 18 lines, which have been studied in all the years of research. We have identified the lines belonging to classes I, II, III, V, VI, VII and VIII. During the transfer of maize hybrids on a sterile basis the lines of classes I and VIII are those ones which have been of great interest. The self - pollinated lines KV 204, SP 286 (class I) are the reliable fixers of «C» type of CMS. The progeny resulted in the hybridization with any sterile lines is characterized by complete sterility. The new self - pollinated lines KV 498, KV 272, KV 227, SP 357, RD 261 (class VIII) are constant natural fertility-restorers. They are able to fully restore fertility in hybridization with any sterile lines and in any growing conditions

FEATURES OF REGENERATIVE ABILITY IN CUTTINGS OF TECHNICAL VARIETIES OF BIANCO, VIORICA AND RITON
DescriptionThe article presents the results of three years of studies on regenerative processes in technical white one-bud cuttings of resistant varieties of grapes Bianca, Viorica and Riton. The studies were conducted in greenhouse experiments at the Department of Viticulture of Kuban State Agrarian University. It was found, that the cuttings of Viorica varieties had achieved the best ripening, and the worst was Bianca. Varieties of Viorica and Ryton which have rather good level of ripening of the cuttings, had starch in carbohydrates and Bianca variety had sugar. Earlier blooming of buds characterized the cuttings of Ryton. Blooming of the buds of Bianca somewhat delayed. Maximum length of the shoots characterized the cuttings of Bianca, and the lowest – Viorica. The shortest pre-root period (26.3 days) was observed in Ryton, and the longest (29.3 days) – in Bianca. Viorica was characterized by the highest yield of cuttings with 3 roots and more (81.3%), this indicator was a bit less (72.5%) for Ryton. For Bianca it was minimal and it was 26.3%. A similar pattern was observed for the average number of cuttings formed at the roots: the variety Viorica - 9.4 pc.,Ryton - 8.1 pc. and Bianca - 4.3 pc. Thus, cuttings of the varieties of Viorica and Ryton belong to a group with a very high root growing activity and Bianca has an average activity

01.00.00 Physical-mathematical sciences
DescriptionThe article presents the theory of the electromagnetic type of rocket motor. The apparatus consists of a magnetron and a conical cavity in which electromagnetic oscillations are excited. We explain the mechanism of trust in such a device based on Maxwell's theory and the Abraham force. We built a dynamic model of the motor and calculated the optimal parameters. It is shown, that the laws of conservation of momentum and energy for the rocket motor of electromagnetic type are true, taking into account the gravitational field. In simulation, the movement used the theory of relativity. The source of the motion in an electromagnetic drive is the mass conversion in various kinds of radiation. The optimization of the operating parameters of the device is done, namely by the excitation frequency, the magnitude of heat losses of electromagnetic energy by thermal radiation in the IR spectrum, the parameters of heat transfer and forced from the temperature dependence of the resistance of the material of the cavity walls. It was found that the effective conversion of electromagnetic energy in the trust force necessary to minimize the deviation of the excitation frequency of the primary resonance frequency of the cavity. The mechanism of formation of trust under change the metrics of space-time, taking into account the contribution of the Yang-Mills theory and electromagnetic field tensor of energymomentum has been proposed

Description
To increase the productivity of the cattle it is demanded simultaneous distribution of all types of animal feed in the form of balanced feed mixture with a given nutritional value. Balanced feeding of animals can improve their productivity, reduce feed wastage, and include alternative components of feed mixtures in their diets, which have nourishing properties and high digestibility; make and adjust feeding rations. Researches conducted by Russian and foreign scientists, proved the prospects of full feeding of complete feed mixtures, which allow to increase the productivity of animals to 9-30 % and reduce the feed consumption in the calculation of 1 с of milk by 7-8 %. The composition of complete feed mixtures includes sunflower cake, silage, root crops and forage. The process of preparation and distribution of feeds for large horned livestock is the issue of all the necessary components of the feed mixture with a given nutritional value. Saturation of the feed product with extra energy goes during its interaction with the working bodies of technical means for preparation and distribution (TMPD) of different types of food. For preparation and distribution of components of the feed mixture it is necessary to have following facilities, provided with reducing energy intensity and improving the qualitative indicators of processes: for grinding beet fodder and sunflower cake we need disk shredders; for shredding silage and roughage – bearnie and rotor shredders, respectively; for dispensing of beet fodder and sunflower cake – belt conveyor, for dispensing silage and roughage we use disc and drum dispensers, respectively; for mixing sunflower cake - rotary mixers, and for silage, beet fodder and for-age we may use paddle mixers; for distribution of sunflower cake we use rotary feeders, for silage and beet fodder – bin distributors, and for coarse feed we should use conveyor dispensers
