At the Kaz-Metiz LLP plant, there has long been a problem of insufficient drums cooling due to the scale formation, which led to the need for frequent production stops to cool them. To solve this problem, simulation modeling of cooling drums with and without scale was carried out to investigate the heat spread over the body. The results of the stationary analysis in the Ansys application showed the heat propagation across the cross-section of the drum and proved that the resulting scale, having a low thermal conductivity, significantly reduces the heat exchange from the drum wall to water, as a result, the surface of the drum is significantly overheated. Subsequently, the improved drum cooling system was implemented in «Kaz-Metiz» LLP. 2024-01-01T00:00:00Z http://e.biblio.bru.by/handle/1212121212/45336 Современные тенденции и направления развития научной коммуникации Дуктова, Л. Г.; Шарапова, Е. В.; Duktova, L. G.; Sharapova, A. V. В статье рассмотрены два аспекта научной коммуникации. Во-первых, изучается коммуникация по апробации результатов научного исследования и формированию репутационного капитала ученого внутри профессионального сообщества. В числе основных тенденций, влияющих на развитие научной коммуникации, - цифровизация, с которой связано появление и функционирование электронных библиотек, создание профилей ученых в электронных базах данных, использование возможностей искусственного интеллекта для популяризации научного знания, мониторинг развития глобального пространства университетской науки с помощью рейтингов (например, ARWU, THE WUR, QS World University Rankings, Webometrics, Ranking Web of Repositories), рост проектов, связанных с реализацией такого направления корпоративных стратегий компаний, как социальная ответственность (патронирование исследований молодых ученых) и др. Вовторых, изучается научная коммуникация, связанная с популяризацией научных исследований и формированием имиджа ученого для массовой аудитории. Среди основных направлений работы структурного подразделения научной организации (учреждения), связанного с PRдеятельностью, - работа с журналистами, организация, проведение и освещение научных мероприятий, специальных мероприятий, управление коммуникативными ресурсами организации, являющимися источниками информации и площадками для коммуникации в научной коммуникации и др. The article deals with two aspects of scientific communication. First, the communication on approbation of research findings and formation of the scientist’s reputational capital within the professional community is examined. The main trends affecting the development of scientific communication include digitalization, which is associated with the electronic libraries emergence and functioning, the creation of profiles of scientists in electronic databases, the use of artificial intelligence to promote scientific knowledge, monitoring the development of the global space of university science through ratings (e.g., ARWU, THE WUR, QS World University Rankings, Webometrics, Ranking Web of Repositories), an increase in the number of projects related to the implementation of such a direction of corporate strategies of companies as social responsibility (patronizing the research of young scientists), etc. Secondly, science communication related to the popularization of scientific research and the formation of a scientist’s image for mass audiences is investigated. The main directions of work of a structural unit of a scientific organization (institution) related to PR-activities include cooperation with journalists, organization, holding and coverage of scientific events, special events, management of communication resources of organizations as sources of information and communication platforms in scientific communication, etc. Мақола ду ҷанбаи иртиботи илмиро баррасӣ мекунад.

В. This paper presents a study of transverse and longitudinal arithmetic average roughness of carbon fiber-reinforced plastic (CFRP) material slotted with three micrograin carbide knurled tools: fine, medium, and coarse toothings. By transverse (respectively longitudinal) arithmetic average roughness, we mean roughness measured perpendicular to the advance direction (respectively in the advance direction). The purpose of this work is to implant a theoretical model of transverse arithmetic average roughness highlighting his dependence on only tool geometry, to validate it experimentally and to define an empirical model of longitudinal arithmetic average roughness for each knurled tool. From the results of ANOVA, it is concluded that feed per tooth makesthehighest statistical and physical influence on surface roughness. Experiments show that knurled tool fine toothing is the suitable tool for slotting of CFRP because it produces less damage to the laminate plate. 2016-01-01T00:00:00Z
