The interaction of oppositely charged polyelectrolytes (sodium salt of carboxymethylcellulose (NaCMC), methylcellulose (MC), polyethylenimine (PEI) and polydimethyldiallylammonium chloride (PDMDAAС), and unifloc (UF)) in an aqueous environment was studied using the methods of viscometry, spectrophotometry and macroelectrophoresis. It has been established that the interaction of these polyelectrolytes is accompanied by a significant decrease in reduced viscosity (up to 0.1-0.15 dl/g, which is typical for compacted macromolecules of globular proteins), an increase in optical density and an inversion of the sign of the electrokinetic potential. All this indicates the formation of interpolymer complexes from interacting cationic and anionic polyelectrolytes. Experimental results of studying the properties of water soluble polymers and their polyelectrolyte complexes in aqueous solutions at the water/air interface are described and discussed. It has been shown that complex formation in relatively simple systems is accompanied by changes in the pH of the medium, optical, hydrodynamic, electrochemical and other properties of macromolecules. In the systems we studied, the interaction of the system components is not accompanied by variations in the pH of the medium, therefore, information about the interaction of water-soluble polyelectrolytes in the systems we studied was obtained based on viscometric and spectrophotometric titration data, as well as from changes in the electrokinetic potential of macromolecules. The study of the electrokinetic potential showed that the formation of interpolymer complexes in the systems under consideration is accompanied by significant changes in the electrokinetic potential of macromolecules. A study of the properties of mixtures of aqueous solutions of Na-CMC, MC, UF with polydimethyldiallylammonium chloride and polyethylenimine indicates the formation of interpolyelectrolyte complexes that have a more compact structure than the original macromolecules.

The article reveals the problem of using an online platform as a basis for implementing pedagogical interaction on the Internet using various telecommunication channels with on-line or off-line modes, mass communications, social network services to enhance the cognitive activity of students. The concept of “educational online platforms” is revealed, on which innovative teacher tools for organizing an interactive educational process are located, which are in demand when implementing programs for the study and application of interactive technologies in education, since on their basis it is possible not only to provide theoretical and practical educational materials, but also to implement the very interactive interaction of participants in the educational process. The article describes innovative learning technologies, including types of online platforms and ways of using them in the educational process. Thus, the word interactive - the term interaction refers to the tendency to talk or communicate with someone (a person) or with someone (such as a computer) in an interview manner. Innovative educational work is formulated through the rational introduction of new technologies that adapt the educational process to productive learning. These include modern technologies such as cable and satellite television, video conferencing, teleforums, telethons, portfolios, personal achievements in education and training, and life skills training, including social learning, among which various achievements are mentioned.

The Koshkar-Ata waste storage, which has no natural runoff, has been used for many years to collect chemical and metallurgical products, a chemical hydrometallurgical plant and a sulfuric acid plant, to store transported solid waste, to store seawater, which then turns into steam, \"acidic water\" (untreated running water) was used as a source of reception for household needs of the upper small areas). The technogenic impact of such sources of environmental damage, the ecological danger lies in the pollution of groundwater and the possibility of dense salts and harmful substances with a strong toxic effect entering the sea (in hydraulic connection with the seawater reservoir and district complexes), saving the Koshkar-Ata landfill from dusting beaches from wind erosion, lowering the surface of the water mirrors, which leads to the denudation of the shores, is determined by the factors of transformation of the waste warehouse into a radioactive swamp. Topical issues include measures and studies aimed at preventing evaporation from the surface of the water mirror of the Koshkar-Ata waste storage tank, as well as cleaning bare shores from \"swamp\" waste, re-fertilization of land. To effectively solve the problem of the Koshkar-Ata waste accumulator, various complex methods have been proposed for many years, such as reducing the evaporation of water from the sump, re-fertilizing the coastal territory, but due to the vastness of the Koshkar-Ata waste landfill, it is too early to say that a solution to this problem has been found. Studies have established that a decrease in the water surface of the tailing dump occurs due to the combined impact of a complex of natural factors on the reservoir. These factors include a strong wind (movement of atmospheric layers of air), water temperature, the presence of certain substances in the water (in addition to salts of mineral origin). In any case, there is evaporation of water from the surface of the tailing dump into the atmosphere, shallowing of the coastal zone, and exposure of sands, which causes the formation of fine dust that adversely affects the human body.

In the article, we examined the determination of the degree of soil contamination from two sections of the city. The method we used in our study is the bioindication method. Bioindication methods make it possible to assess the state of the environment with the help of living objects without special expensive equipment, devices and reagents. The relevance of bioindication is also due to the simplicity, speed and low cost of determining the quality of the environment. For example, when the soil is salinized in the city, the linden leaves turn yellow at the edges even before the onset of autumn. You can identify such areas simply by examining the trees. In such cases, bioindication makes it possible to quickly detect the most polluted habitats.Some living organisms are very sensitive to environmental changes, and with their participation, size or developmental features, it is possible to assess natural processes, conditions and anthropogenic changes in the habitat.

This article discusses the poetic works of many poets about the legendary Makhambet, whose life and work is of great value to our history, as a fiery fighter for the freedom of his native land and his people, and as a poet and famous akyn-improviser, who struck the listener with sharpness and passion , wisdom and humanity of the sounding word, which left a bright mark in the national culture. The art of Makhambet is a popular theme in poetry, and many poets dedicated poems to the hero, glorifying the heroism and spirit of the great poet. The courage and heroism of Makhambet is depicted in the works of poets. In their lyrical poems, they skillfully sang the image of the great poet and fighter through the rational use of the best artistic alternative images - images that show the height, intelligence, eloquence, sharpness, individuality, grandeur, depth of Makhambet's poetry. Lyrics in the art of the artistic word is a special genre that leads the poet to the innermost feelings, to the abyss of subtle thoughts. The works in this genre are not limited only to the manifestation of the individuality of the individual, the reflection of the characteristics of each poet in cognition, feeling of the world. At the same time, they allow us to determine the epochal nature of the path of genre changes, growth, prosperity, decline of lyrics in the process of literary development as a whole. The article is devoted to the problem of continuity of traditions in Kazakh poetry, including as a poetic tradition of the militant poet Makhambet Utemisuly, who has passed through the centuries and has reached our days. The manifestations of intertwining literary traditions in the national literature were considered.
