In the article, the pedagogical skills of pedagogues in the process of teaching physics, and the psychological characteristics of young people in mastering physics are widely covered. The 21st century, as an age of intellectual potential, thinking and spirituality opens up new horizons for humanity and also creates acute problems that we have not seen or faced before. In the course of solving the problems arising in the field of education, pedagogues should, in addition to providing education to young people in today's complex times in the spirit of the times, think about the tomorrow of humanity, our Motherland and our people, and carry out educational work aimed at encouraging young people to virtue, honesty, kindness and tolerance. is required. The successful solution of educational issues in the teaching of physics requires teachers to know the psychological laws of the process of personality formation, the abilities of young people and individual differences in psychological development, the direction of the student's personality, the qualities of will and emotions, the characteristics of cognitive activity and mental development. due to this, opinions were expressed about the continuity of school and higher education in teaching science. If teachers manage to get young people to know the concepts and ideas of modern physics from the beginning, there will be no need for them to read them again. if it is compiled and applied to the lesson process, it will be of great importance in increasing the effectiveness of education. This is the level of development of society and the modern state requirements imposed on the existing education system, and based on them, it includes state measures to guide schoolchildren to the profession. ensures that he chooses his career path and finds his place in life according to the essence of his work.

The paper offers a theoretical examination of approaches for identifying hazardous and risky elements in the working environment. Four typical study methodologies have been identified for identifying risks in labor processes. The norms for classifying working conditions are analyzed, and findings are provided, depending on the variables of unsafe production at work and the factors of harmful production, in fact, how much has increased from the norms.

Many owners of small food enterprises industry, as well as owners of small and medium-sized grocery stores, weigh and pack their products by hand. Especially owners of small and medium-sized food processing plants such as Chiwda have to carry out the process of weighing, filling and packaging manually. The sealing process is carried out using candles. This process requires a lot of time and effort and therefore limits their production and business.

In this work, a mathematical model of the concentration distribution of gallium and antimony elements theoretically doped into silicon by diffusion method was studied using the MathCad program. The essence of theoretical calculations and mathematical modeling of the diffusion process is not to waste experiments, to determine in advance the depth of penetration of the impurity atoms into silicon from diffusion, and to plan the experiments and increase the productivity of the results.

Statistics have indicated that industrial accidents of ammonium nitrate were primarily caused by uncontrolled external fires where heating was dominantly controlled by radiation, and yet existing studies at milligram scale cannot fully simulate the real fire scenarios. To explore the pyrolysis behavior in typical fires, this study conducted thermal radiation experiments using pure ammonium nitrate, and its mixtures with copper oxide and sulfuric acid. Different from the pyrolysis process identified in milligram scale tests, the bench-scale pyrolysis of ammonium nitrate under radiation consisted of four stages. Pyrolysis structure model of each stage was built to reveal the differences in dominated thermal behavior. Results indicated that two additives had different thermochemical effects on pyrolysis of ammonium nitrate. Sulfuric acid accelerated the reaction rate of each stage by generating catalytic nitric acid; copper oxide reduced the number of reaction stages into three via surface absorptions. The time and mass loss rate of different stages were determined. Recommendations on effective emergency response were made to prevent the transition of slow decomposition into fast decomposition, and thus to intervene the fire-induced domino effect of ammonium nitrate. This study helps to understand the pyrolysis behavior of ammonium nitrate under fire exposure, and provides insights for pyrolysis modeling and firefighting in industry of interest.
