Description
Sunflower is one of the most important oilseed crops, which are of great economic importance in Russia and in the world. It is very adaptive crop in terms of climatic conditions range, for that reason it is cultivated on a vast territory of the Russian Federation in various weather conditions. Sunflower oil has high nutritional and taste qualities, it is used numerously in food and is applied in various fields of food industry. The biologically active linoleic acid, phosphatides and fat-soluble vitamins A, D, E and K, which are of great nutritional value to humans, are contained in the oil. According to its calorific capacity, sunflower oil is on the first place among vegetable oils. Due to biological characteristics of sunflower, the Krasnodar region is the most favorable region of the Russian Federation for obtaining high and stable yields of this crop. However, here the drought is observed during the summer period and it affects adversely the productivity and quality of sunflower seeds. The increasing of resistance to unfavorable weather conditions is possible only based on detailed study of physiological features of productivity formation and seeds quality that is highly important task in view of the current geopolitical situation in Russia. One way of solving this issue is the appliance of the growth regulators, possessing anti-stress activity that improve the quality of sowing seeds and increase the productivity and plant resistance to stressful environmental factors. These drugs include growth regulator called Furolan, which was created in KubGTU and is certified for use in Russia. It is not toxic and is used in nano-dozes, there is no its residual quantities in the products and environment. Furolan has a positive effect on physiological and biochemical processes, improves the productivity of plants, their resistance to unfavorable growing conditions by increasing the resistance to dehydration as well as to the risk of fungal diseases

CLARIFICATION OF A MODEL OF A BALANCING ROBOT BY LOGICAL AND EMPIRICAL METHODS
01.00.00 Physical-mathematical sciences
DescriptionThis work studies the mathematical model of the object “inverted pendulum” on the example of the unstable electromechanical devices which is balancing robot on wheel couple. Unfortunately, many details of object model are unknown. Logical and empirical method offers hypotheses about the difference between the actual object model from its mathematical approximation based on logical analysis with subsequent refinement of this model and testing of the hypothesis with modeling of the systems with the updated model. As a result, the amendments to the model have been found containing nonlinear components. With the help of these amendments, the dynamic characteristics of the actuator, filters, friction and the tendency of the object to fluctuations are better taken into account

GENERAL FACTORS INFLUENCING THE EFFICIENCY OF IMPLEMENTATION OF EGOVERNMENT
DescriptionThe article discusses the development of e-government concept and the key factors that have a major impact on this process. In this study, the external environment is defined and we have specified the inner enlarged structure of the system. The influence on the development of the concept is exploring with factors of external and internal environment. The influence of factors on the formation of the paradigm of egovernment is showing on the example of historical development. Further, successful practice in the establishment of e-government are analyzed and then are noted some problems arising in this process. The accumulated international and local experience is studied in this area, that is reflected in list of practical experiments and theoretical studies by group of scientists. E-government is examined not only as the management structure, but also as the information technology system. Key trends are analyzed and the impact of factors is discovered in relation to selected components of the system of e-government. The article reveals the factors responsible for the success of egovernment implementation and the factors that increase the risk on the project. Low-level factors are grouped on its subjects to identify the basic and secondary groups of factors, which affect selected elements of the system. It defines the elements of egovernment affected with the general impact

MECHANIZATION OF HARVESTING AND PROCESSING OF TOMATOES
DescriptionThe article has a research character which is expressed through the analysis of ways and means of mechanization for harvesting of solanaceous vegetables, and also endurance from works of scientists on the studied subject. Vegetable growing is an important branch of agricultural production. From a set of vegetable plants the increasing significance is attached to cultures which production contains physiologically active agents. Solanaceous vegetables belong to these cultures. In Russia, vegetables on an industrial basis are cultivated in the south of the country. Everywhere in Russia crops of vegetables are reduced. It is explained by high costs of production, especially on harvesting that at the general deficiency of manual skills leads to reduction of the areas, violation of technology of cultivation and harvesting and, respectively, to decrease in productivity. In conditions import substitution of foreign agricultural production and increase in the areas of landing of vegetable cultures in the Russian Federation for creation of a safety cushion food in the conditions of food embargo, undoubtedly, will be required the maximum mechanization of technological process of cleaning of vegetables. The most important results of types of designs of machines for vegetables and, problems of use of modern machines for cleaning of vegetable cultures are given. Our own design for harvesting solanaceous vegetables is offered

DETERMINATION OF ACUTE TOXICITY OF ROKSATSIN
DescriptionIn this article, the authors have defined the acute toxicity of Roksatsin preparation, which represents a 20 % aqueous solution of polyhexamethylene guanidinehydrochloride (PHMG). The acute toxicity of Roksatsin in the first series of experiments was studied on white mice upon intragastric administration. In the second series of the experiments, Roksatsin was administered subcutaneously to white rats and in the third series of experiments the preparation was administered intracisternally to cows. The results of the first series of experiments showed that Roksatsin by the internal method of appointment is slightly toxic to white mice. In this experiment not been a single case of acute intoxication and death of animals. Experiments to determine the acute toxicity of the preparation for white rats were performed in triplicate. In the first series of experiment, the LD50 was 4.8 ml/kg. It is found, that the calculated coefficients LD50 for other two series were close to the first one: the second - 4.2 ml/kg and the third - 4.5 ml/kg. Therefore, the authors found that the Roksatsin preparation upon subcutaneously administration according GOST 12.1.007-76 is a low-toxic compound (4th class of danger). As a result of the third series of the experiments, it was found that the intracisternally administration of Roksatsin preparation to cows in a dose of 5 ml is not toxic to the animal organism. Intracisternal administration of Roksatsin does not have a significant impact on the morphological and biochemical indices of blood. On this basis, Roksatsin preparation with different routes of administration is low-toxic and it can be recommended for clinical researches

EFFICIENCY OF ROKSATSIN IN AEROSOL DISINFECTION OF THE LIVESTOCK BUILDINGS
DescriptionThe authors briefly describe the properties of polyhexamethyleneguanidine hydrochloride (PHMG), which refers to a broad-spectrum biocide and has antimicrobial activity against Gram-negative and Gram-positive bacteria, viruses and fungi. PHMG has a deodorizing effect, gives the treated surfaces long bactericidal effect, which can be stored depending on the surface and other external factors from 3 days to 8 months. The authors have presented data about the level of bacterial and fungal contamination of air in the dispensary before and after aerosol treatment of Roksatsin. Bacterial contamination of air dispensary determined via the sedimentation method (Koch Method), which is settling microflora (in air), under gravity, on the surface of a growth medium. For the determination of total bacteria and fungi in 1m3 of air the authors make calculations of total aerobic microbial count (TAMC) according to the formula that was proposed by V.L. Omelyanskii. Bacterial contamination of air was evaluated before disinfection. Accounting quality of aerosol disinfection performed by sedimentation microflora on Petri Dishes through 30, 60 and 120 minutes of exposition. In the analysis of the data the authors defined that Roksatsin as a disinfectant has a negative effect on pathogens, namely significantly reduced the content of pathogenic and conditionally pathogenic bacteria and fungi in the air, so it can be used for preventive and compelled aerosol disinfection of air in the livestock buildings
