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

Project Assignments Assessment in the Content-Integrated Language Course: Stages, Forms, and Online Tools

Today, according to various educational documents, a university teacher must be able to control the learning process not only in order to compare the level achieved by students with a certain minimum of requirements laid down in the curriculum on the basis of competent and transparent assessment criteria and to record changes in the general level of preparedness of each student and the dynamics of his successes, but for the diagnosis of problems that arise among students in the learning process (formative assessment); for the development of reflection skills; skills of self-assessment and peer-assessment by students of their achievements. Unfortunately, at the current stage, peer-assessment, reflection and self-assessment are a weak point in the educational process, since usually the student does not participate in control and assessment, he is not involved in the process of developing or choosing assessment criteria, in peer and self-assessment, in reflective activity after completing the project assignment or taking a course. The article examines control and feedback as important components of the methodological system: the stages of control, assessment methods, control and reflection tools. The purpose of this article is to develop the approaches for assessing professionally oriented projects within the framework of a content-integrated language course (CLIL). The article analyzes the didactic potential of feedback during project activities and the conditions for providing effective feedback. The stages of web projects’ assessment, the pre requisites for the successful implementation of the activity in blended learning are described as well as online tools and mobile applications that allow to ensure effective feedback, reflection and assessment in a content-integrated language course

The influence of Holstein crossbreeding on the reproductive qualities of Black-and-White cows

The purpose of the research was to study the main indicators of the reproductive ability of Black-and-White cows, depending on the proportion of Holstein genes. As the material for the research there were taken the data of breeding and zootechnical records of cows of Black-and-White breed of CJSC Semenovsky Breeding Plant of the Mari El Republic. The results of the research showed that with an increase in the proportion of thorough-bredness on the Holstein breed the reproductive ability of cows improved. Thus, the first-calf heifers with a low proportion of Holstein genes (up to 12.5 %) had the latest age of the first fruitful insemination and the first calving (21.9 months and 32.3 months). With an increase in thorough-bredness up to 87.6 % and more, the age for the first insemination decreased by 7.7 months (31.8 %), the age of the first calving - by 7.4 month (21.8 %), fertility index increased by 5.8 (14.6 %). At the same time, the duration of the service period in high-blooded animals increased by 18.8-26.4 days (15.8-23.8 %). The duration of the calving interval in all genetic groups exceeded the optimal time and changed in accordance with the change in the service period. The longest calving interval was in cows with the thorough-bredness degree of 87.6 % (13.8 months), which was 0.1-0.7 months longer than in animals of other genetic groups. There was a low coefficient of reproductive ability of the studied animals of all genetic groups ‒ 0.91-0.93. The significant influence of Holstein genes on the age for the first fruitful insemination (ɳ2 = 9.57 %), the first calving (ɳ2 = 8.80 %) and the fertility of cows (ɳ2 = 1.98 %) (P≤0.05) was established. The effect of the genotype on the duration of the service period and calving interval was weak (ɳ2 = 0.09 % and ɳ2 = 0.26 %) and unreliable

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 magnetic properties of mechanically alloyed Fe3-xAlCrx powders

Mixtures of elemental powders of Fe3-xAlCrx composition, where x ∈ (0.8 -1.2) were mechanically alloyed in the AGO-2U planetary ball mill. Obtained powders consist of particles with median size of 0.5-1.6 µm; increase in the Cr content results in the decrease in the size of particles. According to the X-ray data, all of the as-milled alloys possess a single-phase disordered b.c.c. structure. Increase in Cr content results in the decrease in the grain size of alloys, whereas the dependence of the lattice parameter on the chemical composition is not conclusive. Mössbauer spectra for most of the alloys shows that iron atoms in this alloys, in spite of the fact that only one phase was detected using the X-ray diffraction, exist both in ferromagnetic and non-ferromagnetic conditions

ORGANIZATIONAL SUBCULTURAL DYNAMICS IN DIGITAL TRANSOFORMATION PROJECTS

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

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
