The influence of the industrial complex on the atmospheric air in the Sverdlovsk region

The work is dedicated to studying the level dynamics of polluting substances emissions into the atmosphere of Yekaterinburg city and the Sverdlovsk region in the period of 2012-2016. In the process of our work we found out an insignificant reduction of main indicators values such as SI, HR, and IPA to estimate the atmospheric air quality. Nevertheless, the level of the air pollution in Yekaterinburg city remained high in the stated period. We also suggested some methods to reduce enterprises emissions in the article, which will lead to improving the air quality. In the result of our work it was established that the main pollutants are suspended particles, nitrogen dioxides, phenol, and benzene. Moreover, the connection between the atmospheric air pollution degree and the Sverdlovsk region population's health was determined. © 2018 Institute of Physics Publishing. All rights reserved

Frameworks for Formation and Stability of Kurgan Regional Arboretum Phytocenosis

The article is devoted to solving the problem of biodiversity conservation in the framework of increasing sustainability of natural plant communities in arboretum being an artificial protected area. Research and application have accumulated significant knowledge on various aspects of the above problem, specifically, preserving biodiversity including vegetation, monitoring biodiversity and preserving phytocenosis, plant interaction in phytocenosis, causes of disturbed biodiversity and reducing phytocenosis stability, etc. The research objective is to theorize the frameworks for phytocenosis formation, identify the factors influencing phytocenosis stability, conduct observations and experimental research on the factors affecting the formation and stability of the Kurgan regional arboretum phytocenosis. The models of the way different factors influence the resistance mechanisms of the Kurgan regional arboretum phytocenosis are built as a result of studying research materials and differ from the theoretical model in the fact that the proven distinctions were found in the ratio of limiting and background factors reflecting their regional character

Transfer of technology of “Green chemistry” in education

Работа посвящена проблемам «зеленой химии» и внедрению технологий «зеленой химии» в образование. Ученые и преподаватели Уральского федерального университета предлагают раскрыть значимость химии для школьников и студентов бакалавриата и магистратуры, способствовать поддержке талантливой молодежи, будущего нашей науки и производства. Обсуждается один из способов достижения этой цели – реализация проекта «Зеленая химия». Работа в этом направлении с использованием дистанционных технологий обучения позволит увеличить интерес молодежи к химическим наукам.The work deals with the problems of “green chemistry” and the introduction of technology “green chemistry” in education. Scientists and teachers of Ural Federal University offer to reveal the importance of chemistry for high school and undergraduate and graduate students, to help support talented young people, which are the future of our science and industry. One way to achieve this goal is the implementation of the project “Green Chemistry”. The work in this direction with the use of distance learning technologies will increase the interest of young people in the chemical sciences

Method of technical and operational risks evaluation in the process of endoscopes reprocessing

Purpose of the study: Analysis and evaluation of technical and operational risks of flexible endoscopes reprocessing. Materials and methods: Statistical 2016-18yy data of technical and chemicals reprocessing endoscopy rooms equipment and partially data of endoscopes technical service and repairing of Sverdlovsk regional medical facilities have been analyzed. Mathematical analysis has been performed with universal multiply sectioned Bayesian network. Results: Analysis of availability of equipment and chemical consumables evaluated that 85% of endoscopic units use manual reprocessing, which with careful competent approach shows relatively small (22,75%) technical operational risk. Most endoscopy units - 89%, use non enzymatic cleaning solutions and evaluate middle close to high (49,94%) technical operational risk due to potential fixation of micro residual organics, when aldehydes are using for high level disinfection leading for biofilms, which evidently (evidence level A) can destroy endoscopic channels. Aldehyde sare using in 82% endoscopy units, oxygen containing agents based on peracetic acid in 18%. It can be considered as relatively small (24,3%) technical operational risk if use after proper cleaning and exposure modes compliance. Conclusion: Generalized flexible endoscopes reprocessing technical operational risk can be evaluated by analysis of three main criteria: method - manual or automatic, processing chemicals - for cleaning: enzymatic or nonenzymatic, for high level disinfection: aldehydes or oxygen peracetic acid based solutions. Considered risk can be reduced from middle to small (25% and lower) by enzymatic cleaning solutions priority use.Цель исследования: Проанализировать и оценить технико-эксплуатационные риски, связанные с обработкой гибких эндоскопов. Материалы и методы: Проанализированы статистические отчетные данные медицинских организаций Свердловской области за 2016-18гг по оснащению техникой для обработки гибких эндоскопов, обеспечению расходными химическими средствами для обработки и, частично, данные по сервисному обслуживанию и ремонту гибких эндоскопов за данный период. Анализ материала был проведен путем математической обработки данных с построением многоуровневой вероятностной байесовской цепи. Результаты: Анализ обеспеченности техникой для обработки гибких эндоскопов показал, что в настоящее время 85% эндоскопических подразделений применяют ручной способ обработки эндоскопов, что при бережном, грамотном подходе и соблюдении условий обработки представляет относительно низкий (22,75%) технико-эксплуатационный риск для эндоскопической аппаратуры. Большинство подразделений (89%) используют неэнзимные средства для очистки, что несет средний, близкий к высокому (49,94%) риск для техники из-за фиксации мельчайших остатков органических соединений при применении альдегидов на этапе дезинфекции высокого уровня и формировании биопленок, которые, в свою очередь, могут доказано приводить к повреждению каналов эндоскопов. Альдегиды используют для дезинфекции высокого уровня и стерилизации в 82% эндоскопических подразделений, кислородсодержащие средства на основе надуксусной кислоты - в 18% подразделений, что при правильном применении, качественной предварительной и окончательной очистке и соблюдении режимов экспозиции показывает относительно низкий (24,3%) технико-эксплуатационный риск. Заключение: Суммарный технико-эксплуатационный риск при обработке гибких эндоскопов может быть оценен по трем основным критериям: применяемый способ обработки: ручной или автоматический; средства для очистки: энзимные или неэнзимные; средства для ДВУ и стерилизации: кислородсодержащие или альдегиды. Снижению данного суммарного риска от среднего до низкого (25% и ниже) может способствовать выбор средств для очистки на основе энзимов
