Development of the Adolescentsβ Communicative Culture in the Context of Digitalization of Additional Education
In the era of digitalization of education and economy and the development of artificial intelligence, adolescents appear highly competitive compared with other generations in understanding digital technologies, acquiring expertise, and mastering modern means of communication, which normally causes intergenerational conflicts and the loss of an adultβs personal and functional authority. The aim of this research was to develop and test a model for developing adolescentsβ communicative cultures in an institution of additional education. The research emphasizes the significance of personality-oriented, interactive-communicative, and cultural approaches and conducts a comparative analysis of the sources. Methodologically, the study relies on a quantitative method with primary sources. Besides, the findings of the study contribute to the existing limited stress on the importance of adolescentsβ communicative cultures from the perspective of the digitalization of additional education. The study finds that the use of digital options in education has reduced social interaction among students. However, the students prefer to use digital methods of learning as they find them more convenient for communication. Therefore, the digital communication culture has high potential in the educational sector. The findings are novel as this study is one of the few recent studies that examined how communicative culture has transformed due to digital means in education.Β Doi: 10.28991/ESJ-2022-SIED-019 Full Text: PD

The nanocomposites hydrogenation was carried out both in the process of synthesis and under pressure (6 MPa) for 20 minutes. Dehydrogenation process was fulfilled by heating to 700 Β°Π‘ at a rate of 1 Β°Π‘/s. Magnesium hydride formation occurred only in the composite of Mg-Ni-C for nanocomposites which were hydrotreated under synthesis. The decomposition of this hydride was took place under the 644 Β°Π‘. In case of nanocomposites, hydrogenated under pressure, the magnesium hydride decomposition start temperature in the Mg-Ni-C was 300 Β°Π‘, in the Mg-Ti-C β 450 Β°Π‘. Thus, the nanocomposite Mg-Ni-C provides the best conditions for the hydrogenation / dehydrogenation of hydrogen

Efficiency of industrial crossing of meat, dairy and combined cattle
The scientific article presents the results of a scientific experiment conducted to study the quality indicators of beef obtained from interbreeding of cattle of meat, dairy and combined breeds in the conditions of the Volgograd agricultural enterprise JSC "Berdievsky Elevator". The resulting crossbred bulls at the age of 9 months were divided into 4 groups of 10 heads each according to the principle of pairs of analogues: I experimental group of Β½ crossbreed (Kazakh white-headed x Russian brown), II experimental group of Β½ crossbreed (Kazakh white-headed x Aberdeen-Angus), III experimental group of Β½ crossbreed (Aberdeen-Angus x red steppe), IV experimental group of Β½ crossbreed (Simmental x red-mottled). The formed groups of animals were put on fattening up to 16 months of age. The growth dynamics of bulls and the qualitative characteristics of beef were evaluated
