ENERGY-LOADING OF DISKS IN FRICTION PAIRS OF “DISC-PAD” OF BRAKING DEVICES IN VEHICLES (part two)
DescriptionIn the materials of the article we mention the regularities of changes in the volume and surface solid temperature gradients and self-ventilated brake discs and illustrate their impact on the main operating parameters of the friction pairs of disk-to-pad brakes of the A 172 bus; the relationship between thermo-physical parameters of polished and matte surfaces with areas of brake discs of various types. The influence of the type of tests on the pairs of loaded with energy friction disk and pad brakes of the vehicle. We have set the intensity of heat exchange processes from the surfaces of the brake discs of various types. It is shown that this leads to increased surface temperature gradient. The volume and the surface temperature gradients of the brake discs were determined with the involvement of the hypothesis of summation of temperatures on the surface when you post the generated electric currents. It was found that in the surface layer of the working surface of a solid brake disc at its pulse heating under the influence of the temperature of the flash nucleate cracks due to the thermal fatigue of the material of the disk. The features of the design of the brake discs were considered as well. On the basis of the calculation and the experimental data we have shown a correlation between the emissivity of brushed and polished surfaces and their areas in the disk-to-pad brakes when using solid and self-ventilated discs

ENERGY-LOADING OF DISKS IN “DISC-PAD” FRICTION PAIRS OF BRAKING DEVICES IN VEHICLES (part one)
DescriptionWe’ve illustrated assessment of energy-loading of disk-pad brakes of the bus A172 in the preliminary stages of tests type I and II according to regulated standards of UNECE and we’ve established regularities of heat exchange processes in the interaction surfaces of solid and self-ventilated brake discs with high-speed currents of washing air

22.00.00 Sociological sciences
DescriptionThe article examines the ethical aspects of online communications in modern social networks. In the course of the study, the function "pumping an avatar", first proposed to users of the social network "VKontakte" on April 1, 2017 as a comic and innovative version of the congratulations on the Day of Laughter of their friends on the Internet, was studied. Some of the ethical aspects of the network innovation under consideration have been identified. The results of a questionnaire survey of students of Kuban State Technical University about the perception of the new online format of the April Fool's Day are given. The factors limiting in 2017 the diffusion of this innovation function among Internet users are considered. The results of the analysis of the reasons for both negative and positive attitude of Kuban State Technical University students to the possibility of making comic visual changes to the account of other users without their knowledge are presented. In the course of the study it was revealed that the individual model of behavior of the respondents on the Day of Laughter in many respects correlated with the model of their friends' behavior on the social network «Vkontakte». There is a hypothesis that if technical barriers to communication are eliminated, the next year may be seen viral effects both in distributing information about the avatar-pumping function itself in the social network, and in distributing content created with it

EFFECT OF ELECTROMAGNETIC FIELD LOW FREQUENCIES IN THE TECHNOLOGY OF DRYING MANGOES AND PAPAYAS
DescriptionThe intensity of drying process depends on the speed of movement of the moisture inside the object and the speed of its removal from the surface. To accelerate the drying process, temperature gradient is often regulated, which causes large power consumption. Currently, they are different methods in used for intensifying the process of drying of plant material which are physical, mechanical, chemical and electrical method. Data of literature review show a lack of data on the impact of synergies of lower frequency on the efficiency of drying plant material. Accelerating the drying process of fruit can be achieved by combining low – temperature of drying with a synergistic lower frequency of electromagnetic field. The results of the studies on the development of technologies to accelerate the drying process of mango and papaya fruit are presented in this article. The role of the electromagnetic field, on the intensification of the drying process and on the inhibition of the microflora of mango and papaya, during drying is studied. Effect of the synergistic electromagnetic fields of different frequencies leading to the death of microorganisms, as well as the drying rate of mango and papaya fruit is analyzed. The optimal technological parameters of low frequency electromagnetic field on drying of mango and papaya fruit are determined. Biochemical changes of mango and papaya fruit during drying are given. Technological parameters of the powder mango and papaya obtained by combining low temperature treatment with the synergy of low frequencies are described
