Authors: Abdulkerimova S. M. , Kulikova A. A. , Dashtieva M. Yu. 
Published: December 2021

Relevance. Today, dental composite materials are very popular among dentists. The composite material is a filler in the form of particles of various sizes immersed in a polymer matrix. Polymer composites are used for direct filling of all groups of teeth and at different depths of the lesion. Composite materials have optimum mechanical, aesthetic and functional properties. They are simple and easy to use, provide long-term restoration service, and also have a wide price range. All these qualities allowed composite materials to firmly gain a foothold in the practice of dentists around the world. In this regard, clinicians and researchers are constantly trying to significantly improve their physical, mechanical, adaptive and aesthetic properties.Aim. Conduct a systematic assessment of the available scientific data on the effect of accelerated aging of the composite on its physicochemical properties.Materials and methods. In the course of a systematic review of the literature, a study was made of publications in electronic databases such as Google Scholar, PubMed, Research gate, Elibrary. The search results are formatted using the Prisma diagram.Results. Dental composites inevitably age over time and under the influence of environmental factors. To predict the long-term service life of composite restorations, scientists and clinicians are studying the aging behavior of the material. To simulate the clinical conditions of the oral cavity, various methods of artificial aging of dental composite materials have been developed.Conclusions. A study of scientific papers published over the past 10 years on the topic of artificial aging of dental composite materials has shown its unambiguous effect on the mechanical and morphological properties of polymers. The use of methods for simulating clinical conditions made it possible to reduce the study time and analyze the changes obtained.

Relevance. The effect of a tissue engineering construct based on synthetic octacalcium phosphate activated with plasmid DNA with vascular endothelial growth factor gene on bone morphogenesis at the jaw defect sites of patients was studied. It is shown that the studied osteoplastic material stimulates osteosynthesis pathways already at early stages, and xenogenic hydroxyapatite, triggers osteogenesis processes with considerable delay and does not have time to form a full-fledged bone structure by 6 months.Aim. Evaluate the dynamics of reparative osteogenesis based on the results of histomorphometric diagnostics in patients with defects in the jaw bones of various configurations and lengths with an implanted bone matrix based on synthetic octacalcium phosphate activated with plasmid deoxyribonucleic acid with genes of vascular endothelial growth factor.Materials and methods. Histomorphological examination of bone tissue biopsy of jaws was carried out in 50 patients of both genders, who needed additional volume of bone tissue to install dental implantation. Patients were divided into 2 groups by type of grafted material. 6 months after the surgery, bone biopsies were taken from the bone sites at the stage of implant placement. Histomorphological patterns and histomycrophotograms were studied in bone biopcies.Results. In bone tissue biopsies of patients implanted with a tissue engineering construct based on synthetic octacalcium phosphate activated with plasmid DNA with vascular endothelial growth factor gene, it was revealed that after 6 months there was prevaluation of mature bone tissue (42,71%), with the proportion of differentiated plate bone tissue being < 90%.Conclusions. Histomorphometric analysis showed that in patients implanted with a tissue engineering construct based on synthetic octacalcium phosphate activated with plasmid DNA with vascular endothelial growth factor gene, after 6 months, early rearrangement of bone tissue into a mechanically dense and highly mineralized structure was detected.

Published: December 2021

Постановка задачи. Модернизация систем изоляции инженерных сооружений, в том числе и трубопроводов и промышленных объектов, направлена как на решение общих задач энергоэффективности, так и частных задач теплосбережения и экологической безопасности. В связи с этим разработка и применение связующего, отверждаемого при значительно меньших температурах и не содержащего фенолы, является актуальной задачей. Результаты. Эксперимент, проведенный для оценки влияния на адгезию к различным поверхностям комплексного связующего, отверждаемого в температурном интервале от 80 до 140 С, позволил определить оптимальные расходы латентного компонента и модификатора, которые составили соответственно 3,6-4,0 % и (2,6 ± 0,1) % по массе связующего при оптимальной температуре тепловой обработки 100 С. Расчетом установлено, что при переходе от тепловой обработки при 250 С к тепловой обработке при 100 С прямые затраты тепла снижаются на 60 %, а энергетические затраты на изготовление минераловатных цилиндров на 20-30 %. Выводы. Теоретически обоснована и экспериментально подтверждена возможность применения эпоксидного клея на латентных отвердителях в качестве связующего для высокопористых систем с распределением и отверждением этого связующего на тонких минеральных волокнах. Определены характеристические параметры процесса отверждения, длительность которого уменьшается с повышением температуры и содержания латентного отвердителя.
Statement of the problem. The modernization of insulation systems of engineering structures, including pipelines and industrial facilities, is aimed both at solving general problems of energy efficiency, as well as the particular tasks of heat saving and environmental safety. Therefore the development and use of a binder that cures at much lower temperatures and does not contain phenols is an urgent task. Results. An experiment conducted to assess the effect on adhesion to various surfaces of a complex binder cured in the temperature range from 80 to 140 °C allowed us to determine the optimal flow rate of the latent component and modifier, which were 3.6-4.0 % and (2.6 ± 0.1) % respectively by the weight of a binder at an optimal heat treatment temperature of 100 °C. The calculation suggests that when switching from heat treatment at 250 °C to heat treatment at 100 °C, direct heat costs are reduced by 60 %, and energy costs for the manufacture of mineral wool cylinders by 20-30 %. Conclusion. The possibility of using epoxy glue on latent hardeners as a binder for highly porous systems with the distribution and curing of this binder on thin mineral fibers has been justified theoretically and confirmed experimentally. The characteristic parameters of the curing process have been identified whose duration decreases as temperature and the content of latent hardener increase.

Authors: Попов И. И. , Левченко А. В. 
Published: December 2021

Постановка задачи. Работа посвящена экспериментальному определению внутреннего трения в таких материалах, как каучуковые бетоны (каутоны) на основе низкомолекулярного полибутадиенового каучука смешанной микроструктуры марки ПБН и цис-полибутадиенового низкомолекулярного каучука марки СКДН-Н, с помощью метода импульсного воздействия. Результаты. Установлено, что каутон на основе каучука марки ПБН обладает более выраженными вязкоупругими свойствами по сравнению с аналогичным материалом на основе каучука марки СКДН-Н. Введение стальной фибры снижает внутреннее трение в материале, в то время как полимерная фибра дает обратный эффект. Это связано с тем, что волокнистая пропиленовая фибра служит дополнительным демпфирующим материалом, усиливающим диссипацию энергии при динамическом нагружении. Выводы. Впервые измерено внутреннее трение для каутона и фиброкаутона. Полученные данные являются дополнительными микроструктурными характеристиками материалов, описывающими их вязкость. Определены реальные значения исследуемых величин, которые позволяют применять модели с дробными производными при расчете строительных конструкций из каутона и фиброкаутона на динамические воздействия с учетом явления вязкоупругости.
Statement of the problem. The paper is devoted to the experimental identification of damping for such materials as butadiene rubber (BR) and cis-butadiene low-molecular weight rubber (SKDN-N) based concrete and fiber-reinforced rubber concrete by means of the Impulse Excitation Technique (IET). Results. It was found that BR based concrete with or without fiber-reinforcement shows more obvious viscoelastic properties than the corresponding materials based on SKDN-N rubber. The addition of steel fiber reduces internal friction in the material, while propylene fiber has the opposite effect. This is due to the fact that the fibrous propylene acts as an additional damping material, which enhances energy dissipation under dynamic loading. Conclusion. The internal friction in the rubber concrete and fiber-reinforced rubber concrete has been measured for the first time. The obtained data are the additional microstructural characteristics of polymer concrete, which describes its viscosity. The actual values of the investigated quantities have been determined, which makes it possible to use the models with fractional derivatives in the calculations of building structures made of rubber concrete and fiber-reinforced rubber concrete for dynamic loads taking into account the phenomenon of viscoelasticity.

Статья посвящена рассмотрению педагогических аспектов исправительного воздействия в отношении осужденных, совершивших особо опасный рецидив, как сложного социального феномена, детерминирующего эффективность реализации уголовно-правовых отношений. Раскрывается сущность и содержание понятия исправительного воздействия в отношении осужденных, рассматривается педагогический потенциал мер исправительного воздействия, которые в большей степени носят воспитательный характер, не связаны непосредственно с преступлением и не имеют характера возмездия. Авторами статьи анализируется сложившаяся практика реализации исправительного воздействия в отношении осужденных, совершивших особо опасный рецидив, на примере ФКУ ИК-29 УФСИН России по Самарской области, являющегося исправительной колонией особого режима, в которой отбывают наказание осужденные, неоднократно совершавшие тяжкие и особо тяжкие преступления. На основании результатов опроса сотрудников ФКУ ИК-29 УФСИН России по Самарской области и осужденных, отбывающих наказания в указанном исправительном учреждении, делается вывод об эффективности отдельных мер исправительного воздействия, в том числе «встреч с родными и близкими» и «встреч со священнослужителями». Формулируются рекомендации по повышению эффективности мер исправительного воздействия в отношении осужденных, совершивших особо опасный рецидив преступления.
The article is devoted to the consideration of the pedagogical aspects of corrective treatment in relation to prisoners committed especially dangerous repeated offences, as a complex social phenomenon that determines the effectiveness of the implementation of criminal law relations. The essence and content of the concept of corrective treatment in relation to prisoners is revealed, the pedagogical potential of corrective treatment measures that are not directly related to the crime, do not have the nature of retribution, and, to a greater extent, are of an educational nature, are considered. The authors of the article analyze the existing practice of implementing corrective treatment in relation to prisoners committed especially dangerous repeated offences, using the example of a correctional colony with special regime № 29 of the Federal Penitentiary Service of Russia in Samara Region, where prisoners committed repeated felonies and especially serious crimes are held. Based on the results of a survey of employees of the correctional colony № 29 of the Federal Penitentiary Service of Russia in Samara region and prisoners serving sentences in this correctional institution, a conclusion is drawn about the effectiveness of certain corrective measures, including «visits relatives and friends» and «visits priests».

Published: December 2021

В данной статье приводятся примеры исторического искажения некоторых правовых институтов возникновения семейных правоотношений между чеченцами и возникшего в результате заблуждения. Выдающиеся российские кавказоведы второй половины XIX века относят широкое распространение левирата у чеченцев как одну из основных форм брака. Основным из посылов научного исследования будет являться постижение данной проблематики с учетом более глубокого критического изучения и анализа уже существующих работ в области кавказоведения, а также через прямые векторы информации - через непосредственных носителей информации, самих представителей традиционного общества.
This article provides examples of the historical distortion of some legal institutions of the emergence of family legal relations between Chechens and the resulting delusion. Prominent Russian Caucasian scholars of the second half of the 19th century consider the widespread use of levirate among Chechens as one of the main forms of marriage. The main message of scientific research will be the comprehension of this problem, taking into account a deeper critical study and analysis of already existing works in the field of Caucasian studies, as well as through direct vectors of information - through direct carriers of information, representatives of traditional society themselves.

Authors: Korshikov Ivan 
Published: December 2021

Aim. Analysis of the chronological sequence of involvement of woody plants in landscaping of the city of Kryvyi Rih to develop conceptual foundations for their more effective use. Methods. Chronology of species implementation of woody plants in landscaping of the city were studied until the year 2000 on the basis of archival documents, scientific publications, as well as studies of the dendroflora of Kryvyi Rih. Results. In total, 185 species and forms of woody plants belonging to 82 genera were used in the landscaping of the city until the year 2000. In the period between 1870–1910, only 26 species were involved. In the postwar period (1945–1950), the number of species planted in the city was already 38 species, it increased significantly up to 78 species in the 1960s, and the maximum number of species - 90 was used in the landscaping of the city in the 1970s. In the first half of the twentieth century the most common species were members of the genus Acer L., among them A. negundo L., as well as Robinia pseudoacacia L.; species of the genera Ulmus L. and Fraxinus L. 1970–1980 years can be called the era of species of the genus Populus L. Conifers were solitarily planted in the city in the 1950s and 1960s, these are species of the genus Thuja L.and Juniperus L. In the late 1970s and 1980s, species of the genera Picea A. Dietr., Pinus L. and Taxus L. were massively introduced in the city. Today, such species as Picea pungens Engelm., as well as forms of P. pungens f. coerulea and P. pungens f. glauca is most represented among conifers in plantations, slightly less – Pinus pallasiana D. Don and P. sylvestris L. At this time and in the following years, Juniperus sabina L. is widespread in the city. Conclusions. In the urban environment of the XX century, the species, with a high level of vitality, primarily among deciduous Acer, Betula L., Catalpa Scop., Crataegus L., Fraxinus, Gleditsia L., Malus Mill., Morus L., Padellus Vass., Populus, Prunus L., Pyrus L., Quercus L., Rhus L., Sophora L., Tilia L., Ulmus proved to be stable and among coniferous — species of the genera Picea, Pinus, Taxus, Juniperus and Thuja, which are promising for further use.
