Processing of chloride-containing productive solutions after uranium in situ leaching by ion exchange method

The uranium sorption from productive solutions containing chloride ions using anion-exchange resins was investigated. The VPAE ion exchanger had the highest values of the sorption capacity, which for the experiment in the static mode was 13 kg U m -3 , and for the experiment in the dynamic mode, it was equal to 36 kg U m -3 . The use of VPAE anion exchanger will make it possible for uranium recovery from productive solutions with an increased content of chloride without sacrificing the productivity of the sorption plant. The process of saturated resins regeneration by various reagents was investigated. The use of ammonium nitrate solution with sulfuric acid ensured maximum value of uranium recovery from the saturated resin phase (76-97%). © 2019, Gadjah Mada University. All rights reserved

Effect of transplantation of allogeneic multipotent mesenchymal bone marrow stromal cells on regeneration of liver after extended hepatectomy (experimental study)

© 2018 Human Stem Cell Institute. All rights reserved. Multipotent mesenchymal stromal cells can be a drug for treatment of acute liver failure. The purpose of this study was to assess the effect of multipotent mesenchymal stromal cells on the proliferative, mitotic activity of hepatocytes and morphometric criteria for the regeneration of liver parenchyma after 68 % partial hepatectomy in rats. The number of mitosis, PCNA positive cells, diameter of nucleus of hepatocytes, size of hepatocytes, nuclear-cytoplasmic ratio (NCR), the area of hepatic lobules were evaluated on 1, 2, 4, 14 days after surgery. The results of the study showed that intravenous administration of allogeneic mesenchymal multipotent stromal cells from bone marrow after extended hepatectomy increase the number of proliferating hepatocytes (PCNA positive cells), but does not affect the number of mitoses, the diameter of the nucleus, the area of hepatocytes, NCR and hepatic lobules. Probably, at this time, regeneration proceeds primarily through an intracellular mechanism

Conditions for the formation of a non-autonomous phase at the structural deformation of complex vanadium oxides

Received: 02.03.2018. Accepted: 10.04.2018. Published: 10.05.2018.A new previously unknown effect of a reversible transition from a singlephase system to a heterophase system containing a non-autonomous phase was observed during thermal and chemical deformations of the Zn2–2xCd2xV2O7 structure.The role of local symmetry in the formation of the non-autonomous phase is shown on the basis of X-ray diffraction studies in situ and a comparative crystal-chemical analysis of the structural deformations of isoform monoclinic solid solutions of zinc and copper pyrovanadates with zero volumetric thermal expansion.The work was supported by UB RAS (project 18-10-3-32)

Structure and properties of the intercalation compound FexTiTe2

The FexTiTe2 system, which belongs to the class of materials with the electronic spectrum containing below the Fermi level the band of localized states with a strong temperature dependence of the band width, has been investigated experimentally. Heating of the material leads to a broadening of the band of localized states. When the top of this band crosses with the Fermi level, the effect of retrograde solubility is observed in the system; i. e., the metal precipitates to the composition ensuring the absence of increase in the Fermi energy during heating. The influence of the band of localized states on the structure of the material and its magnetic and electrical properties has been analyzed. © 2013 Pleiades Publishing, Ltd

ОЦЕНКА ЭКОНОМИЧЕСКИХ ЭФФЕКТОВ ОТ КАСТОМИЗАЦИИ ПРОДУКЦИИ РОССИЙСКИХ ПРОМЫШЛЕННЫХ ПРЕДПРИЯТИЙ

The development of digital production technologies, taking place within the framework of the global fourth industrial revolution, creates conditions for increasing the level of customization of industrial production, i.e. the ability to manufacture products that reflect the preferences of small groups of consumers and even individual customers. Product customization, as one of the most important aspects of the fourth industrial revolution, is of great interest for researchers and has been becoming one of the promising trajectories for the development of new production technologies and methods of organizing production. But at the same time, the economic effect of increasing the customization of products remains not fully understood. This study is aimed at identifying various economic effects arising from customization in industrial enterprises, and their quantitative assessment in relation to the manufacturing industries of the Russian industry. Using a systematic review of available scientific research and analytical reports, the study quantifies the economic effects of customization in various sectors of the Russian economy. The results show the colossal effect of further customization in Russian enterprises. The authors conclude that the annual effect of revenue growth in all industries, even under the most pessimistic scenarios and estimates, is 1.9 trillion rubles, and the effect of cost reduction – 1.4 trillion rubles. The results obtained can form the basis of government measures to stimulate the customization of products of Russian industrial enterprises.Развитие цифровых технологий производства, происходящее в рамках глобальной четвертой промышленной революции, создает условия для повышения уровня кастомизации промышленного производства, то есть способности создавать продукцию, отражающую предпочтения небольших групп потребителей и даже индивидуальных клиентов. Кастомизация производства как один из важнейших аспектов четвертой промышленной революции вызывает огромный интерес со стороны исследователей и становится одной из перспективных траекторий развития новых производственных технологий и методов организации производства. При этом экономический эффект от повышения кастомизированности продукции остается не до конца изучен. Настоящее исследование направлено на выявление различных экономических эффектов, возникающих от кастомизации на промышленных предприятиях, и их количественную оценку применительно к обрабатывающим отраслям российской промышленности. С помощью систематического обзора имеющихся научных исследований и аналитических обзоров в исследовании производится количественная оценка экономических эффектов от кастомизации различных отраслей российской экономики. Результаты свидетельствуют о колоссальном эффекте от дальнейшей кастомизации производства. В результате расчетов авторы приходят к выводу, что годовой эффект от роста выручки по всем отраслям промышленности даже при самых пессимистических сценариях и оценках составляет 1,9 трлн руб., а эффект от снижения затрат – 1,4 трлн руб. Полученные результаты могут лечь в основу государственных мер по стимулированию кастомизации продукции российских промышленных предприятий

ВНУТРИОРГАНИЗАЦИОННАЯ СУБКУЛЬТУРНАЯ ДИНАМИКА В ПРОЕКТАХ ЦИФРОВОЙ ТРАНСФОРМАЦИИ

The article aims to investigate the negative impact from organizational subcultural dynamics in digital transformation projects on number of conflicts and quality of communications and to elaborate proposals how to improve cross-subcultural communications within the projects. The methodology of the study includes participatory action research and case study. The network model of project culture helped to identify two cultural coalitions and their values. The model of the subcultural coalitions and their values helped to formulate the scope of communicational trainings and changed in the project communication system. The focus of the measures was on the preservation of the existing subcultures and on the improvement on the cross-subcultural communications. Comparing the number of conflicts within project before implementation of the measures based on the research and after it showed significant positive impact of these measures. The main findings show that in multidisciplinary and complex projects, such as digital transformation projects, subcultural dynamics can lead to formation of different coalition that do not share common values. This can be the source of the conflicts and low quality of communications. However, using the knowledge of coalitions’ structure and values the management of companies can enhance cross-subcultural interfaces without decreasing positive effect from subcultural diversity. Цель исследования состояла в изучении негативного влияния субкультурной динамики внутри проектов цифровой трансформации на уровень конфликтов и качество коммуникаций и выработке решений по конструктивному использованию разнообразия организационных субкультур. Основной методологией выступало партисипаторное исследование действием и исследование конкретной ситуации. Была построена сетевая модель организационных субкультур, которая позволила выявить наличие устойчивых коалиций внутри проектных команд и их ценностные установки. На основе модели субкультур были разработаны коммуникационные тренинги и внесены изменения в систему проектных коммуникаций. При этом акцент делался на сохранении субкультурного разнообразия и повышении эффективности кросс-культурных коммуникаций. Сравнительный анализ количества конфликтов и качества коммуникаций до и после предложенных мероприятий показал их высокую эффективность. Полученные результаты позволяют сделать вывод, что в мультидисциплинарных и организационно сложных проектах цифровой трансформации субкультурная динамика может проявляться в возникновении устойчивых коалиций, культурные ценности которых плохо согласованы. Но знание структуры коалиций и их культурных ценностей позволяет оптимизировать их взаимодействие без потери положительного влияния от субкультурного разнообразия на эффективность и креативность команд
