In the article presents the results of studies on the effect of temperature and pressure on the chloride sublimation of zinc and lead from converter dusts of steel production. Currently, an objective necessity is the development of dust utilization technologies for converter steel production, with its further use in production and production of by-products. The use of dust allows not only to save natural raw materials, but also increases production efficiency and improves the environmental situation. The content of non-ferrous metals in dusts makes it difficult to process and use them in agglomeration or in blast furnace production, while the iron content in converter dusts (sludges) makes it possible to use them as promising metallurgical raw materials. Therefore, for a more complete processing of dusts, extraction of non-ferrous metals from them is proposed. The purpose of this work was to determine the possibility of extracting zinc and lead from sludges of the converter production by the method of chloride sublimation. We used dust containing: 86,3 % Fe2O3, 3,5 % FeO, 0,9 % Al2O3, 1,6 % CaO, 0,9 % MgO, 1,1 % MnO, 0,8 % SiO2, 4,4 % ZnO, 0,5 % PbO. The study was conducted in the temperature range 200-1600 degrees C and pressures of 0,01; 0,1 and 1 bar based on a complete thermodynamic analysis using the HSC – 5.1 software package. Finnish metallurgical company Outokumpu, based on the principle of minimum Gibbs energy. According to the results of the studies, it was found that, at normal pressure, lead chloride sublimationbegins at a temperature of 600 degrees С, and zinc - at 900 degrees С: a decrease in pressure to 0,01 bar reduces the temperature to 500 degrees С and 700 degrees С, respectively; lead chloride sublimation under equal conditions is more complete than zinc; To achieve zinc chloride distillation at the level of 90-96 %, the process must be carried out at 1145-1200 degrees С and pressure from logP = -2 to 1,2 bar, while the degree of lead chloride distillation is 99,8-100 %.

The widespread introduction of information technologies makes significant changes in various spheres of human activity. The education sector is no exception. In this regard, in this article, the author considers the actual problem of developing electronic textbooks and is one of the most relevant and promising areas of informatization of the educational process. The analysis of the works of scientists A.A. Andreev, A.I. Bashmakov, T.I. Koval, V.M. Kukharenko, E.S. Polat, P.I. Serdyukov, S.S. Sysoeva, A.Yu. Uvarova was conducted. These works contain requirements for the development of electronic textbooks. Based on the results of the analysis, the author described the stages of developing electronic textbooks, the principles that they should correspond to, and also provided a list of modules that should make up an electronic textbook. From the existing variety of software packages, the author distinguishes CourseLab, Smart Builder, MOS Solo, Google Sites, iSpring Suite, TurboSite, Adobe Animate, HTML5. The development of electronic textbooks based on the technology presented by the author of the article and their subsequent application in the educational process will help to organize the educational and cognitive activities of students at a more effective level. Purpose is the description of the technology for the development of electronic textbooks, taking into account existing requirements. The article uses methods of analysis, synthesis and deduction. The analysis of requirements and principles of development of electronic textbooks is carried out on the basis of the descriptive-analytical method. The practical result of the proposed technology is the developed electronic textbook "Development of mobile applications". The results of the study, in addition to their theoretical significance, also have practical significance, which consists in the positive dynamics in resolving the contradiction between the continuously increasing flow of information and the limited opportunities of students to assimilate it. The conscious use of electronic textbooks in the educational process is one of the fundamental ways to improve the quality of education by changing the methods of teaching used in the direction of individualization and focus on the student.

The development of extraction techniques of medical plants aims to maximize the bioactive compounds production. Тechnologies in this area of industry have not high enough еfficiency factor. In some cases, it reaches only 40-50 %. Therefore, development of new methods to effectively extract different compounds from plant material and their input into large-scale industry is of great importance. The goal is to determine an effective and suitable technology for extracting bioactive compounds from medical plant. This is a narrative review paper which focuses on different extraction methods of medical plant. To find relevant articles for this narrative review, 73 articles were reviewed. Of these, 14 irrelevant documents were discarded. This review analyses various extraction processes to guide the selection of suitable methods for various types of medical plants and applications. This is done by outlining traditional and modern methods of extraction techniques, exploring the importance of solvents for extraction, and comparing novel and alternative methods of extraction. In conclusion, based on the current knowledge, solvent extraction is the most common method for medical plants extraction. Enzymatic hydrolysis and supercritical extraction are advanced techniques with high yield of compounds. However, more research is needed for some modern extraction methods.

Injuries among domestic animals account for 50-70 % of all non-communicable diseases. Fractures of bones, mainly limbs, occur in 44.5 % of cases. The main goal of fracture treatment is to restore normal function and movement of the limb, and the ways in which this is done are varied. Preference is given to methods that do not constrain the movement of the limb, allowing the animal to use it during the treatment period. Purpose: This article discusses the method of bone osteosynthesis, which has proven itself in the treatment of bone fractures, and is relevant today in veterinary medicine. The main study was conducted on the basis of the veterinary clinic "Shans" in Pavlodar. For osteosynthesis, plates for osteosynthesis and screws made of titanium alloy were used. This is due to the fact that when in contact with each other, the metal that fixes bone fragments can oxidize. Animals come to the clinic as a result of injuries that lead to fractures. The most common causes include falls from a height, motor vehicles, careless or rough handling of animals, and contact with other animals. When a fracture is established by obvious signs or if a fracture is suspected, such patients are preliminarily sent for x-rays. Upon receipt of an X-ray image and with the consent of the owner of the animal, osteosynthesis is performed. When accessing bone fragments, the incision was made along the muscle fibers. Osteosynthesis was performed according to the method described by V.M. Shapovalov (2009). The general condition of the animals after osteosynthesis was restored after 3-5 days. All animals, after bone osteosynthesis, completely relied on the limb. Contractures of adjacent joints and muscle atrophy were not determined. Plain osteosynthesis of the femur, in the presence of the necessary instrument and consumables, is not very difficult to perform. Performing bone osteosynthesis in the early stages makes it possible to include the limb in the locomotory act, as a result of which the animal actively uses the limb during the rehabilitation period.
