The benefits of information technology for children with disabilities' academic development are covered in the article. Information technologies may be used to help teach children with hearing impairment the principles of developmental education, improve the ways in which the educational process is organized, and make the transition from mechanical assimilation to the mastery of real skills that allow one to independently acquire new knowledge. The article analyzes the structure and technology support of the development of vocational education for students with hearing impairment. Particularly, the instructional and rehabilitation technologies of the aforementioned group of students' contents have been mentioned.

In accordance with the requirements of the International Organization for Standardization and other organizations, standards are used in order for manufacturers to enter consumer markets or foreign markets and increase their competitiveness. For international standards and national standards of foreign countries, as well as for models of international rules and norms, the installation, parameters, dimensions and quality of the normative unit also includes production technology, testing and control methods, product placement, design and storage. Product certification is carried out to assess the conformity of product characteristics, to verify the product's compliance with the technical and legal requirements of the relevant market.

A copolymer of styrene and α-methylstyrene was obtained by the method of emulsion copolymerization in the presence of an ammonium persulfate initiator and various emulsifiers at a mass ratio of the initial monomers of 70 : 30. The emulsifiers were used as ionic (sodium oleate, potassium oleate, potassium stearate, a mixture of oleate and potassium stearate), and non-ionic emulsifiers (OS-25 and OS-50). The yields of the copolymer in the case of using ionic emulsifiers were 74–85%, and the maximum yield was observed only when using a mixture of potassium oleate and stearate (1 : 1). When using nonionic emulsifiers OS-25 and OS-50, the yields of the copolymer were 75–90%, the highest yield was obtained when using emulsifier OS-50. The molar ratio of styrene and α-methylstyrene units, determined by 1H NMR spectroscopy, was 8 : 3. It was found by IR spectroscopy that the copolymer of styrene and α-methylstyrene obtained using potassium stearate has minimal residual amounts of emulsifier due to its low adsorption by the resulting copolymer . In the case of using sodium or potassium oleates and their mixtures, very weak characteristic frequency bands appear, which are characteristic of the carboxyl group of emulsifier molecules, which indicates their inclusion in the synthesized polymer chains as comonomers. In the case of using nonionic emulsifiers OS-25 and OS-50, the copolymer cannot be washed away from them, despite the fact that the emulsifier molecules are not covalently bonded to the copolymer. The good adsorption of emulsifier molecules on the hydrophobic surface of the copolymer is associated with the presence of hydrophobic alkyl and ethylene fragments in the structures of the molecules of these emulsifiers and the inability to ionize the terminal OH groups under normal conditions.

The study was designed to screen individual Azotobacter genera bacteria strains for a wide spectrum of properties and several physiological properties related to plant growth during experiments. In the experiments, the antagonistic properties against five different pathogens were tested. Studies were conducted against isolates of these five types of pathogens F oxysporum f sp vasinfectum, Fusarium oxysporum f sp lycopersici, Rhizoctonia solani. It showed a positive result in broad-spectrum biocontrol of isolated strains resistant to the development of five different pathogens. In the extended antagonist test, these strains were observed together with bacteria of the Azotobacter genus as a biological control against major plant pathogens such as F oxysporum f sp vasinfectum, Fusarium culmorum, Fusarium graminearum, Fusarium oxysporum f sp lycopersici, Rhizoctonia solani.

The article highlights the essence of Avesta dualism and the problems of its manifestation in all aspects of material and spiritual life. In particular, in Avesta, the religious and philosophical teachings of ideas about the material and spiritual world are described in the form of personification. The evolution of Zoroastrianism is not limited to the fantasy of animism, but also includes a gradual reflection on the origin and end of life. In the article, the dualistic worldview characteristic of Zoroastrianism is analyzed in the context of a person's naive immersion in fantasy, rising to the level of rational perception of nature and mental phenomena. In fact, in Zoroastrianism and the Avesta, the material and spiritual world is not only a matter of thought (consciousness), but rather, it is one of the special features of Zoroastrian religion as a vision of the division of the whole material world and the world of spirits, ruled by Ahura Mazda and Anhra Mainyu.
