AN ELECTRIC MODEL OF A CITY TRANSPORT NETWORK
DescriptionThe main characteristics of a transport network are the intensity of the traffic flow, speed and density of its traffic. Comfortable driver's traffic density is determined by the rule of the traffic police, which is "clearance between cars on the road should be a tenth of the speed of movement." We have built a reference curve of the density function of the flow of vehicles on its speed, which is basic when simulating a traffic flow. The article describes a model of electrical city transport networks, allowing calculating traffic flows, their speed, the density and the number of traffic lanes by means of laws of electrical engineering. We have also compared electrical concepts (current, resistance, electro-motive force, etc.) and transportation (of intensity-flow lane road, transport driving force, etc.). For the transport network there are methods of calculation of electrical circuits - a method of Kirchhoff's laws, loop currents, etc. We have confirmed the correctness of electric models and the possibility of its use for the calculation of transport networks; as well as we have presented an example of the calculation

EXPERIMENTAL STUDY OF NOISE AND VIBRATION OF THE BAND SAW FRAME SAWS AND WOODWORKING MACHINES
DescriptionThe article presents the results of experimental studies of band noise generation and multirip woodworking machines. The studies have shown that saw woodworking group, as well as metal, are general patterns in the formation of the spectral composition that allows to approach the development of practical recommendations to reduce sound pressure levels in the work area to the operators of sanitary norms. Of particular note is the fact that elevated levels of noise generated by the cutting tool. The effect of changes in process parameters, in particular, the depth of cut and feed to levels of noise generated by the tool. For example, increasing the depth of cut in half leads to an increase of sound pressure levels at 5.8 dB (theoretically obtained value is 6 dB), and supplying a halving of the sound pressure levels reduces by 5 dB. High enough for engineering purposes convergence of theoretical and experimental sound pressure levels and the fact that the calculated values above experimental, allows the calculation and design of the system to reduce the noise under consideration in the machine is, only in service but also in their design

EXPERIMENTAL RESEARCH OF HYDRODYNAMICS SOURCE CYLINDRICAL COLLECTORS OF HEAT EXCHANGERS
DescriptionIn this article, we represented the scheme and parameters of a pilot model of a source cylindrical collector of the heat exchanger. Influence to a field of velocities on withdrawal from a collector of various nonuniformities of submission of a cost of the heat-carrier on an input of a collector, and influence of a hydraulic resistance on withdrawal from a collector on uniform of a stream of the heat-carrier is experimentally established

Description
The article provides an overview of the phytosanitary condition of crops for 2011-2014 g in the Krasnodar region. In recent years, we can observe increasing of the crop losses from pests and diseases of plants. The using of different pesticides in intensive cultivation technologies of winter wheat can’t resist this. Pathogenic microorganisms acquire resistance to drugs used and become more aggressive. This creates a lot of environmental problems. Plants are almost always under environmental stress. However, it is impossible to refuse of pesticides. And they are not able to observe the immune system of the plant, and in some cases inhibit it. The present level of development of science has led to the emergence of new methods of plant protection, which is based on increasing of the capacity of the immune plants, rather than the destruction of pathogens, as in the case of the use of pesticides. We propose to apply so called "agrochemical cocktails"

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

Description
In the article we present questions of digital process control of heated air for drying seeds; it is shown that the change in the load of the heat source slightly changes the dynamics of the system for stabilizing the temperature of hot air, making it almost invariant with respect to perturbations. It is proved that the use of digital controller with dual differentiation significantly improves the performance of the automatic control system, excluding the increase astatism of the management system
