Description
The modern level of development of the industry requires creation of more difficult and high-precision systems of an electric actuator allowing executing precisely and correctly the given technological processes. As these devices, we may consider hybrid or cascade systems of an electric actuator. However, for creation of such devices we require new design approaches, or specification and improving of the existing theories and methods of design of classical systems. The main difficulty in calculation consists in determination of parameters of electromagnetic system. In this article, new approach is given in finding of electromagnetic parameters of components of an asynchronous controlled cascade electric actuator taking into account real geometry. This approach was formed during creation of the program complex, which is a part of a system of automatic design

EFFICIENCY IMPROVEMENT IN THE NATIONAL RICE BREEDING AND SEED PRODUCTION
DescriptionThe article reviews economic aspects of efficiency improvement of the national breeding capacity in rice growing. It is noted that there are no foreign rice varieties in the RF State Register of Breeding Achievements approved for use. However, only 2 - 3 leading rice varieties cover more than half of the rice acreage and thus reducing the efficiency of the existing varieties potential of the economic sub-sector. The critical importance of breeding and the wide-spread introduction into production of rice varieties resistant to disease is highlighted. The cyclic and growing occurrence frequency of blast as the most harmful disease of rice is shown. The data are provided on the increase of the annual cost of the rice crop and fungicide treatment and reduced yields of different varieties of rice during epiphytoties. A refined formula is proposed for calculating the annual economic effect of the introduction of new rice varieties. The formula takes into account changes in yield components, grain quality, the cost of breeding and introduction of new varieties, as well as the potential cost savings due to rice resistance to blast. The seeds of domestic long-grain rice varieties and exclusive varieties resistant to blast are available for the Russian market. For a wider introduction into production of all local bred rice varieties, it is necessary to actively develop seed production, improve market research as well as the management efficiency in plant breeding and seed production

DescriptionImproving the quality of Russian cognac is of great national importance. It should be noted that about 80% of Russian foreign brandies made from aged cognac distillates. To obtain high-quality products necessary technical-chemical control of production starting from the vine and the conditions of its growth. For a comprehensive evaluation of the totality of important factors: climate, relief, soil and variety. It is important to add that this grading must be accompanied by the release of environmental macro zones with viticulture specialization. In this regard, there has been conducted a soil-cartographic survey of lands of ACE "Fanagoria" in the Temryuk district of the Krasnodar region. Evaluation took place in view of all 4 factors, notably the soil factor; and the content of lime in the soil and the degree of salinity of soils. Soil analyzes were carried out in FGBNU Anapa ZOSViV SKZNIISiV using the latest equipment generally accepted methods for determining indicators of soil characteristics. The purpose of the research - to give a detailed description of the survey area, as well as highlight the boundaries of environmental macro zones for the cultivation of grapes brandy. During the research, it was found that for the selection and evaluation of raw material zones for brandy production we must take into account soil and climatic optimum performance to get quality brandy raw materials

Description
The authors have developed and manufactured a large number of different designs of relative helical drums for mixing animal feed. We have conducted 749 field experiments with the drums of the 10 different designs with different parameters modes of operation. In all experiments, we measured the quality of the feed mixture. However, directly based on empirical data, rational choice of design features and parameters of the operation modes of the reels is not possible. For this, you must first develop a model reflecting these empirical data. The construction of meaningful analytical models of different types of drums is a difficult and demanding scientific task, the complexity of which is due to the large variety and complexity of forms of drums and their mode of usage, a large number of diverse physical factors affecting the processes in the drum. As a consequence, the development of analytical models associated with a large number of simplifying assumptions that reduce their versatility and reliability. Therefore, it is important to search of a mathematical method and software tools provide a quick and simple for the user to identify and influence the design of the drum and the parameters of the operating modes on the quality of the feed mixture directly on the basis of empirical (experimental) data. The work proposes a solution to this problem with the use of a new universal innovative method of artificial intelligence: automated system-cognitive analysis (ASC-analysis) and its programmatic Toolkit – universal cognitive analytical system called "Eidos". In the system of "Eidos" we have implemented a software interface that provides direct input into the system large amounts of empirical data from Excel file. Created on their basis in the system of "Eidos" system-cognitive model allows the visual form to reflect the effect of the structure of the drum and the parameters of the operating modes on the quality of the resulting feed mixture and to develop on this basis the science-based and appropriate recommendations for the rational choice of design features and parameters of the modes relative to the screw drums. We have also given a numerical example

SEED GERMINATION OF SPECIES RANUNCULACEAE OF YAKUT FLORA
DescriptionThe work was done based on the collection of the natural flora of the Yakut Botanical Garden. The object of research was the seeds of 22 species of the family Ranunculaceae. It is known that the seeds of many buttercup characterized morphophysiological tranquility associated with hypoplasia of the fetus (Nikolaeva, 1988; 1999), due to what delayed the germination of their seeds. Laboratory germination of seeds of the studied species varies from 0 to 100%. Among them, we have not found the kinds seeds which have explosive or fast germination (1 type of seed germination). The germination of the studied seeds states ranging from 6-7 days or more. The studied seeds were evenly distributed between 2 (12 species), and 3 types of seed germination (10 species). Type 2 is characterized by slow germination, type 3 - poor germination or lack of it

Description
The results of the study of amino acids of white table wines depending on the yeast strain, continuous contact of wine with yeast biomass and the presence of lees stirring are presented. The dynamics of amino acids, which affect wine organoleptic characteristics and the formation of wine defects, specifically, tyrosine, methionine, threonine and lysine is shown. Conducted researches made it possible to divide the amino acids into three groups depending on the carrying out the batonnage or lack of it. The first group consisted of amino acids, the concentration of which practically has not changed in the presence or lack of stirring. The second and third groups include amino acids, the concentration of which increased and decreased, respectively during batonnage. The stirring of the wine with yeast biomass facilitated to the activation of mass transfer processes between cell and medium, and the access of air lead to oxidation of some amino acids and the change of its concentration. The absence of stirring influenced to a slight increase in the concentration of such amino acids as cystine, cysteine, β-phenylalanine, serine, α-alanine, leucine and glutamic acid. The experimental data allowed to arrange amino acids in a row depending on the speed of release into the medium: ά-aminobutyric acid > glutamic acid > α-alanine > leucine

SOUND EFFECTS INFLUENCE ON THE OPERATOR’S ORGANISM IN PRODUCTION CONDITIONS
DescriptionHere we present a brief survey of noise effects on human’s organism in production conditions, including noise effects on operators of machines and technical devices. It is well known, that any biological organism exists in balance with its environment. However, noise effects being stress factors knock the operator of machines and technical devices out of the working rhythm and cause different kinds of health disorders such as blood pressure increase, fatigue, disorders of the central nervous system and gastrointestinal tract and the like. All this may lead to accident situations, reduction of labor productivity and quality of work. Frequently health disorders start with hearing impairment which leads to disorientation in the threedimension space and malfunction. It is because the hearing apparatus as biological system provides the organism with sensory information and ensures selfpreservation. In the noise conditions, these characteristics are conflict: on one hand, the hearing organ should possess high enabling capability to receive positive signals, and on the other hand, in order to adapt to the sound hearing and sensitivity will decrease. The duration of noise exposure and the number of years spent under influence of the noise are also of great importance. Thus, it is obvious that control of the noise and prevention of harmful effects of the noise on machine operators are important components of production process in the agrarian sector
