Evaluation of the current state of aquatic ecosystems and the problems of the protection of biological resources during development of kruzenshternskoye gcf

The results of studies of the current state of freshwater ecosystems and their biotic components in the western part of the Yamal Peninsula are presented in the article. Based on the evaluation of the structure of communities of phytoplankton, zooplankton, benthos, and whitefishes, the range of problems related to the protection of biological resources during the development of the Kruzenshternskoye gas field is defined. The data on species composition and quantitative indicators of hydrobionts of different types of waterbodies and watercourses in the lower reaches of the Mordyyakha and Naduyyakha Rivers basins is the basis for environmental monitoring of water objects during development and exploitation of the Kruzenshternskoye gas field. Estimation of the fish fauna state and their food base in the territory of the Kruzenshternskoye GCF according to the monitoring program is present. The river delta zones are the most important feeding areas of the salmonid and whitefishes valuable fish species in the territory of Kruzenshternskoye GCF. In cases where water bodies and watercourses are not completely demolished for the construction of GCF facilities, changes of quantitative and qualitative characteristics of communities of hydrobionts after the end of operations are reversible. River ecosystems are restored within a shorter period of time in comparison to lacustrine ones. Proposals for the protection of fisheries resources and monitoring of aquatic ecosystems on the basis of comprehensive studies are reported. Recommendations on reducing the anthropogenic impact on aquatic ecosystems in the development period are present. The results of the investigation were used in the development of the environmental protection part of the Kruzenshternskoye deposit project. Anthropogenic disturbances present now on the gas deposit territory of Kruzenshternskoye does not influence the aquatic ecosystems.The article have been prepared within the Project of the Presidium of the Russian Academy of Sciences № 12-P-47-2013 and "The Arctic" Project of the Presidium of the Ural Branch of the Russian Academy of Sciences № 12-4-3-012

Competition of Mesoscales and Crossover to Tricriticality in Polymer Solutions

We show that the approach to asymptotic fluctuation-induced critical behavior in polymer solutions is governed by a competition between a correlation length diverging at the critical point and an additional mesoscopic length-scale, the radius of gyration. Accurate light-scattering experiments on polystyrene solutions in cyclohexane with polymer molecular weights ranging from 200,000 up to 11.4 million clearly demonstrate a crossover between two universal regimes: a regime with Ising asymptotic critical behavior, where the correlation length prevails, and a regime with tricritical theta-point behavior determined by a mesoscopic polymer-chain length.Comment: 4 pages in RevTeX with 4 figure

Scaling and Crossover to Tricriticality in Polymer Solutions

We propose a scaling description of phase separation of polymer solutions. The scaling incorporates three universal limiting regimes: the Ising limit asymptotically close to the critical point of phase separation, the "ideal-gas" limit for the pure-solvent phase, and the tricritical limit for the polymer-rich phase asymptotically close to the theta point. We have also developed a phenomenological crossover theory based on the near-tricritical-point Landau expansion renormalized by fluctuations. This theory validates the proposed scaled representation of experimental data and crossover to tricriticality.Comment: 4 pages, 3 figure

Probing structural relaxation in complex fluids by critical fluctuations

Complex fluids, such as polymer solutions and blends, colloids and gels, are of growing interest in fundamental and applied soft-condensed-matter science. A common feature of all such systems is the presence of a mesoscopic structural length scale intermediate between atomic and macroscopic scales. This mesoscopic structure of complex fluids is often fragile and sensitive to external perturbations. Complex fluids are frequently viscoelastic (showing a combination of viscous and elastic behaviour) with their dynamic response depending on the time and length scales. Recently, non-invasive methods to infer the rheological response of complex fluids have gained popularity through the technique of microrheology, where the diffusion of probe spheres in a viscoelastic fluid is monitored with the aid of light scattering or microscopy. Here we propose an alternative to traditional microrheology that does not require doping of probe particles in the fluid (which can sometimes drastically alter the molecular environment). Instead, our proposed method makes use of the phenomenon of "avoided crossing" between modes associated with the structural relaxation and critical fluctuations that are spontaneously generated in the system.Comment: 4 pages, 4 figure

Integration of engineering education and business education as a driver of the development of national economies of post-Soviet countries

На основі аналізу даних соціологічного дослідження, проведеного в рамках міжнародного науково-дослідного проекту БРФФД-ДФФДУ на тему «інтеграція інженерної освіти і бізнес-освіти в технічних університетах України і Білорусі як фактор розвитку національних економік», виявлено високий рівень мотивації і готовність студентів інженерних спеціальностей Національного технічного університету України «Київський політехнічний інститут ім. Ігоря Сікорського» (Київ) і білоруського національного технічного університету (Мінськ) займатися промисловим підприємництвом. Обґрунтовується, що технічне студентство країн колишнього радянського Союзу може бути соціальною базою переходу до ринкової інноваційної економіки, за умови здійснення інтеграції інженерної освіти і бізнес-освіти в технічних університетах для підготовки інженера-підприємця (подібна інтеграція вже існує в західних країнах). Аргументується (з урахуванням відповідного міжнародного досвіду), що існує висока потреба в підготовці інженера-підприємця в пострадянських країнах, оскільки дана соціальна фігура є ключовою в комерціалізації технічної творчості – глобального тренду, запущеного в західних країнах в ході розвитку промислового капіталізму і обґрунтованого в концепції інноваційної економіки видатного австрійсько-американського економіста Й. Шумпетера. Публікація містить результати досліджень, проведених за грантової підтримки Державного фонду фундаментальних досліджень України за конкурсним проектом Ф73/24456 «Інтеграція інженерної освіти і бізнес-освіти в технічних університетах України та Білорусі як фактор розвитку національних економік».The article is based on the analysis of sociological data from a survey carried out within the framework of the BRFFR-SFFRU international research project entitled «The integration of engineering and business education in technical universities of Ukraine and Belarus as a factor of national economic development». The research demonstrates a high level of motivation and readiness of students specializing in engineering in National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute" (Kiev) and Belorussian National Technical University (Minsk) to engage in industrial entrepreneurship. The study convincingly proves that the technical students of the former Soviet countries can be a social base for the transition to a market-based innovation economy subject to the integration of engineering education and business education in technical universities for the training of entrepreneur-engineer (such integration already exists in Western countries). Taking into account the relevant international experience, it is argued that there is a high need for training an engineer-entrepreneur in the former Soviet countries, since this is a key social figure in the commercialization of technical creativity – a global trend launched in Western countries during the development of industrial capitalism and grounded in the concept of innovative economy by a famous Austrian-American economist, J. Schumpeter. The publication contains the results of studies conducted with the grant support of the State Fund for Fundamental Research of Ukraine on the competition project F73 / 24456 "Integration of engineering education and business education in technical universities in Ukraine and Belarus as a factor in the development of national economies.На основе анализа данных социологического исследования, проведенного в рамках международного научно-исследовательского проекта БРФФИ-ГФФИУ по теме «Интеграция инженерного образования и бизнес-образования в технических университетах Украины и Беларуси как фактор развития национальных экономик», выявлены высокий уровень мотивации и готовность студентов инженерных специальностей Национального технического университета Украины «Киевский политехнический институт им. Игоря Сикорского» (Киев) и Белорусского национального технического университета (Минск) заниматься промышленным предпринимательством. Обосновывается, что техническое студенчество стран бывшего Советского Союза может быть социальной базой перехода к рыночной инновационной экономике при условии осуществления интеграции инженерного образования и бизнес-образования в технических университетах для подготовки инженера-предпринимателя (подобная интеграция уже существует в западных странах). Аргументируется (с учетом соответствующего международного опыта), что существует высокая потребность в подготовке инженера-предпринимателя в бывших советских странах, поскольку данная социальная фигура является ключевой в коммерциализации технического творчества – глобального тренда, запущенного в западных странах в ходе развития промышленного капитализма и обоснованного в концепции инновационной экономики выдающегося австрийско-американского экономиста Й. Шумпетера. Публикация содержит результаты исследований, проведенных при грантовой поддержке Государственного фонда фундаментальных исследований Украины по конкурсному проекту Ф73/24456 «Интеграция инженерного образования и бизнес-образования в технических университетах Украины и Беларуси как фактор развития национальных экономик

Consensus position of endocrinologists and pathologists on coding causes of death in patients with diabetes mellitus (expert opinion)

Coding of the causes of death of patients with diabetes mellitus (DM) in the Russian Federation is one of the long-discussed problems, due to the comorbidity of diabetes and cardiovascular diseases (CVD) and a number of contradictions in the key regulatory documents regulating the statistics of mortality in this category of patients, which acquires particular relevance in the context of the coronavirus pandemic, due to its negative impact on the outcomes of the course of COVID-19 and mortality risks. In pursuance of the decisions of the Minutes of the meeting of the working group under the project committee of the National Project «Health» on identifying patterns in the formation of mortality rates of the population dated January 20, 2021 No. 1, chaired by Deputy Prime Minister of the Russian Federation T.A. Golikova, experts of two directions - endocrinology and pathological anatomy, prepared a Draft of agreed recommendations on the Rules for coding the causes of death of patients with diabetes, causing the greatest problems in terms of the use of ICD-10 when choosing the initial cause of death, including in the case of death from CVD and COVID-19

Успешное применение комбинированной экстракорпоральной поддержки жизнеобеспечения при лечении новой коронавирусной инфекции, осложненной развитием полиорганной дисфункции у беременной

Pregnant and postpartum women are at a higher risk of infection with SARS-CoV-2 as well as a higher risk of adverse outcomes for the mother and fetus. Standard approaches to the management of COVID-19-associated multiple organ dysfunction may not always be implemented in this category of patients. In the clinical case of a patient, who developed multiple organ dysfunction syndrome (severe ARDS, coagulopathy) associated with COVID-19 in the postpartum period, we demonstrate the successful use of combined extracorporeal life support that included veno-venous extracorporeal membrane oxygenation, therapeutic plasma exchange and renal replacement therapy with the universal oXiris set.Беременные и родильницы подвержены более высокому риску заражения новой коронавирусной инфекцией и неблагоприятным исходам как для матери, так и для плода. Стандартные подходы к ведению полиорганной дисфункции, ассоциированной с COVID-19, не всегда могут быть осуществлены в этой группе больных за счет измененной физиологии дыхательной системы у беременных и неблагоприятного влияния на плод. На примере пациентки, у которой на фоне COVID-19 развился синдром множественной органной дисфункции (острый респираторный дистресс-синдром тяжелой степени (PaO2/FiO 2 96), коагулопатия), продемонстрировано успешное применение в послеродо­вом периоде комбинированной экстракорпоральной поддержки жизнедеятельности, сочетающей в себе вено-венозную экстракорпоральную мембранную оксигенацию, терапевтический плазмообмен и заместительную почечную терапию с использованием универсального сета oXiris
