This paper is devoted to analytical and experimental modeling of the method of ultrasonic purification of recycled exhaust gases of internal combustion engines. The scheme of the experimental stand ...and the procedure for conducting the experiment are given. The data on determination of the coagulation coefficient are presented.
A brief analysis is given of the modern instrumental methods of monitoring the ash content of coal. Their particulars and drawbacks are examined. A neutron gamma-method of monitoring the ash content ...is proposed on the basis of integrated use of prompt γ-radiation accompanying inelastic scattering of fast neutrons and radiative capture of thermal neutrons by nuclei of the primary elements comprising the organic and mineral components of coal. The instrumental-methodological parameters of monitoring (sizes of the analyzed samples, energy intervals of the detected gamma radiation) making it possible to the increase the sensitivity of the method with respect to the ash content and to minimize the impact of the variability of the moisture content of coal on its material composition, are optimized. The method has been certified and recommended for representative monitoring of the quality of coarse coal.
The methodological features of determining the ash content in coal using scattered gamma radiation are considered in the present study. Theoretical and experimental studies have shown that the ...integral intensity of secondary (scattered and fluorescent) radiation can serve as an instrumental signal depending on the quality of coal. To achieve a more unambiguous relationship between the integral radiation intensity and the ash content in coal of variable material composition, a compensation technique has been proposed consisting in artificial attenuating secondary radiation. The laws governing the integral intensity of radiation depending on the inverse thickness of the filter are studied, and the results are found to be invariant with variations in the ash composition. A model has been developed to optimize the filtering parameters of secondary radiation by considering the regularity of changes in the filter inversion thickness depending on the ash content.
The aim of the article is a comprehensive approach to addressing the digitalization of education in the Republic of Kazakhstan based on identifying problems in this area, forming priority tasks and ...possible ways to solve them. Implementation of IT-programs in the learning process making serious additions to the pedagogical requirements, ethics, and discipline of students also the content of the disciplines. All these aspects are becoming especially relevant today when the quality of education is becoming a strategic task and the key to the successful development of the country’s economy in the digital era. The article touches on the problems of the modern “digital” generation, its dependence on communication in social networks and instant messengers, the impact of this dependence on health and the level of knowledge. The algorithm for educational technologies will be the main educational goals: the ability to think outside the box, be creative in solving problems, and develop logic and intelligence. Therefore, to formulate requirements for training ICTs, it is necessary to implement measures to assess the effectiveness of implemented programs based on experimental data. Such studies are being conducted today to improve the quality of the educational process, which means that they can be used for ICT. In conclusion, if to base on the results of the survey, the main problems were identified and a number of tasks were set for a deeper study, a general idea was formed on the scope of the forthcoming work and the goals for its achievement.
