Evaluation of the output of lime is made for three options for the use of Ferroalloy gas: when you use the physical heat of the gas; when using the chemical energy of the gas and the location of the reactor after scrubbing; when sharing of sensible heat and chemical energy of the gas. As a result of the calculation of the expected yield of lime, it was found that the use of Ferroalloy gas for the production of lime can fully provide or at least compensate for the deficit of lime in the production of steel. The technology of calcination of limestone with Ferroalloy gas is presented in the form of a cycle synchronized with the smelting of steel, including, in accordance with the gas outlet from the layer and their alternation with pauses of inter-blowing periods. The preliminary technological characteristics of firing obtained as a result of theoretical analysis are used for further experimental and theoretical studies.

The article is devoted to the current problem of differential diagnosis of diseases of viral etiology in farm animals. Viral diseases are currently widespread, occupy a leading role in the infectious pathology of farm animals, causing enormous economic damage. Given the magnitude of animal vaccine prophylaxis, in order to increase the effectiveness of antiepizootic measures, the urgent issue i s the development of methods for the rapid and effective detection and differentiation of field and vaccine strains of the infectious rhinotracheitis virus in cattle. The possibility of using a polymerase chain reaction to identify and differentiate a vacc ine strain from epizootic strains and isolators of the cattle infectious rhinotracheitis virus is considered. In the process of research, a PCR-RFLP analysis method was developed to detect the IRT virus in the test material. The PCRRFLP analysis method was used to identify and differentiate the vaccine strain TK-A form epizootic strains and isolators of the cattle IRT virus. The principle of PCR, based on repeated repetition of DNA cycles, annealing and synthesis, which leads to an increase in the number of specific DNA fragments of the pathogen, allows you to take into account the results of PCR in an agarose gel. Analysis time is about 30 hours. The sensitivity of detecting viral DNA is 1-10 picograms (102 TCD). Due to characteristics such as relative simplicity and reaction rate, high sensitivity, specificity and reproducibility, PCR has recently become widespread in basic and applied research in various fields of biological science, including veterinary virology. The results obtained during the studies show that the use of PCR-RFLP allows to differentiate field and vaccine strains and isolates of the IRT virus with a high degree of reliability. The use of PCR -RFLP analysis increases the efficiency and informativeness of studies in the molecular epizootol ogy of cattle RTI, as it allows not only to identify the DNA of different virus strains regardless of their nature, but also to differentiate between them, including differentiating the strain TK-A used for the production of attenuated vaccines against epizootic strains and isolates of the virus.

The article describes modern pedagogical technologies of teaching a foreign language in primary school and examines their impact on the development of various competencies of primary school students. The authors emphasize that information and communication pedagogical technologies help to implement a student-centered approach to learning, provide individualization and differentiation of learning, taking into account the abilities of younger students, their level of education. And also modern pedagogical technologies as a systemic holistic means of restructuring activities make it possible to improve the quality of the educational process, to solve the problems of personality development. Purpose – analysis of modern educational technologies used in English lessons. The current system of training primary school teachers requires a revision of its structure, organization, relationship with school practice and innovative processes in the education system. Therefore, the article proves that an important part of the educational process should be the use of new pedagogical technologies in improving the quality of training of specialists at the university, providing the possibility of self-development of the teacher's personality, increasing his creative abilities and improving the educational process. The study used a descriptive method, analysis and synthesis methods. The authors of the article call the development of the student's personality (moral and cognitive) and the complex of abilities for successful interaction with the polycultural and multilingual world around him as the goal of foreign language education in primary grades. Therefore, it is important that the future primary school teacher, in accordance with the requirements of the state educational standard, has formed the knowledge, skills and abilities necessary for the application of modern pedagogical technologies. At the present time, when a new education system was created, focused on the world educational space, changes in the educational process changed the paradigm of education, updated the content of education, formed a new approach, new relationships. Keywords: technologies, competencies, multicultural, multilingual, English, modern education.

The article compares modern and traditional pedagogical methods used in the process of teaching a foreign language in primary school, differentiates both the advantages and disadvantages of each of them, and indicates ways to supplement the shortcomings of traditional methods with new methods. Currently, the main methods used in teaching a foreign language are being considered. Among the new innovative methods that have recently appeared in the sphere of teaching foreign languages there are community language learning / counseling learning, the sugestopedic method, total physical response, the method of language teaching using information and communication technologies, consciousness-raising approach, task based learning, neuro- linguistic programming, guided discovery, the test-teach-test method. Their influence on the development of language competencies and creative abilities of primary school students are considered. The authors note that the main and most important condition of modern methodology in the process of teaching foreign languages is the creation of an artificial foreign language environment, i.e. the creation of a natural linguistic environment. The authors comment on the concept of "electronic linguistic environment" based on recent research. They show that "digital" children are completely immersed in the computer world, i.e. they live in an electronic linguistic environment and this allows them to solve the tasks of teaching a foreign language. The purpose of the article is to analyze traditional and modern educational methods used in modern English lessons. Activation of the student as the main figure of the educational process, the ability to work in close contact with other students, giving the student the opportunity to work independently, depending on their physiological, intellectual, psychological characteristics, is carried out using individual, paired, group, classroom and other forms of work. Both traditional methods and the latest modern methods are listed among the named teaching methods. Each method has its own characteristics. Therefore, it is very important to consider them in a comparative plan. Each old and new method has its advantages and disadvantages. Therefore, the methodology of teaching English always requires additions and improvements. They are of great importance for expanding the horizons of students, increasing cognitive activity, improving knowledge, skills and language competencies. The authors used the following methods: the descriptive methods, methods of systematization, analysis, interpretation were used in the course of the study. Тhe authors of the article note that methods of teaching a foreign language are of great importance for the comprehensive development of primary school students, obtaining high-quality education, good command of English, achieving good vital indicators, conclude that every teacher should be able to use best practices, developing their creative research and effectively teaching modern English. The results of learning through new methods, such as differentiated learning, project-based learning, communicative learning, information and communication training, etc., providing the formation of personality, its language competencies, will undoubtedly contribute to the independent development of the child, the formation of his language competence, the development of cognitive, creative abilities of students.
