The available data set was checked for compliance with the law of normal distribution. Section 1.2 is devoted to establishing the regularities of the association of cationic polyelectrolytes with alkyl sulfonate anions, and assessing changes in the physical and chemical properties of polyelectrolyte complexes. Section 1.3 discusses the heat capacity of phases from the perspective of the anisotropic crystal model to explain the phenomenon of excess heat capacity of quasicrystalline phases, as well as the fact of stability at higher temperatures of decagonal phases. Section 1.4 analyzes the level of occupational safety in modern production facilities. The influence of artificial lighting on human performance in the course of labor activity was studied. Section 1.5 provides a comparative analysis of modern educational technologies. In Section 1.6, an experimental setup based on Raspberry Pi 3 Model B was developed to measure the current-time and volt-ampere characteristics of dielectric liquids. Section 1.7 is devoted to the development of principles for modeling noise propagation within the airport and adjacent residential areas. Section 1.8 is devoted to the preparation of samples of double lead molybdate crystals, Pb2MoO5, which is promising for use in acousto-optical devices. Keywords: mathematical physics, low-carbon steel, polyelectrolytes, anisotropic crystal, light environment, working conditions, organization of the educational process, educational platform, online resource, learning efficiency, mathematical model, double lead molybdate, Chohralsky method, solid-phase synthesis, dielectric coordinate system, dielectric constant, EPR.
