    The article presents the results of scientific research and industrial experiments aimed at the development of technology to reduce the production cycle of high-strength hull steel. The technology includes an improved reduced heat treatment of ingots made using rare-earth metals and uphill teeming of large sheet ingots. The proposed technology for the preliminary heat treatment of ingots eliminates the high-temperature phase re- crystallization operation, which is unnecessary, according to the authors, since it does not allow partial crushing (grinding) of the metal dendritic structure and homogenization. When using the proposed technology of reduced pre- treatment, phase and structural stresses are sharply reduced. Experiments have shown that the modification of steel with rare-earth metals has a positive effect on the crystallization of ingots, changing the macro- and microstructure of alloy steel. The developed manufacturing technology of high-strength hull steel provides a high level of sheet quality and a reduction in the production cycle time by 10-12 %

    Extraintestinal manifestations and complications of inflammatory bowel disease currently represents one of the most mysterious phenomenon in gastroenterology. Special interest is caused damages of liver, biliary system and pancreas, as constituent organs of the digestive system and first responders not only to inflammation of the intestinal mucosa, but also for medicines taken by patients for induction and maintenance of remission

    Intestinal and Extraintestinal Manifestations of Inflammatory Bowel Disease

    The problem of inflammatory bowel disease draws constant attention not only of gastroenterologists but also surgeons - coloproctologists and other doctors. These related to the growing incidence of this pathology in the world, as well as the diversity of clinical manifestations, including severe extraintestinal manifestations and complications, which in clinical practice, faced not only gastroenterologists. In most cases, inflammatory bowel disease leads to permanent disability cases, which makes this problem not only medical but also socially relevant

    Structure-Sensitive Mechanism of Nanographene Failure

    The response of a nanographene sheet to external stresses is considered in terms of a mechanochemical reaction. The quantum chemical realization of the approach is based on a coordinate-of-reaction concept for the purpose of introducing a mechanochemical internal coordinate (MIC) that specifies a deformational mode. The related force of response is calculated as the energy gradient along the MIC, while the atomic configuration is optimized over all of the other coordinates under the MIC constant-pitch elongation. The approach is applied to the benzene molecule and (5, 5) nanographene. A drastic anisotropy in the microscopic behavior of both objects under elongation along a MIC has been observed when the MIC is oriented either along or normally to the C-C bonds chain. Both the anisotropy and high stiffness of the nanographene originate at the response of the benzenoid unit to stress.Comment: 19 pages, 7 figures 1 tabl

    The article relevance. Modern concepts of education development, recognition of the uniqueness and self-worth of human individuality have led to the search for ways to socialize individuals with disabilities, to the development of new pedagogical strategies aimed at developing ideas of independent life for this category of the population. The research purpose is to study the features and identify ways to improve the quality of inclusive education. Research methods: as a research method, we used a questionnaire survey as a method of collecting primary information, which allows us to identify various aspects related to the problems of formation and perception of inclusive education by participants in the educational process. Research results: the article describes the peculiarity of the current stage of inclusive education development, analyzes the social mechanisms for improving the quality of inclusive education. The novelty and originality of the research lies in the fact that for the first time the correspondence of the existing model of inclusive education to the needs of a significant part of the educational process subjects was investigated. It is shown that, from the point of view of educational services’ consumers, a significant obstacle to improving the quality of inclusive education is the orientation of the education system on results, and not the educational process. It is revealed that the main functions of an inclusive school are educational, career-oriented, educational, and integrative. It is shown that relationships with teachers are a significant factor of psychological stress in inclusive classes. It is found that inclusive classes are sufficiently distanced from interaction with the local community. It is shown that teachers lack the skills of teamwork and confident behavior of the teacher in the presence of another adult in the classroom. It is revealed that the inclusive school is currently characterized by a high level of internal unity, but is not focused on external relations with the local community.  It is shown that parents, unlike students, note the creation of an accessible environment only for certain categories of children with disabilities (including children with musculoskeletal disorders), but not for children with sensory disorders (vision and hearing). Practical significance: the data Obtained in this work can be used in psychological research, pedagogical Sciences, age psychology, as well as for further theoretical development of this issu
