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

Economic and social aspects in the Republic of Tatarstan

The urgency of the problem under study is conditioned by the need to study the state of interethnic and interreligious relations in polyethnic and poly-confessional regions of Russian Federation. The aim of the article is to analyze the situation in the sphere of interethnic and interreligious relations in the Republic of Tatarstan in 2016. The leading approach to the study of this problem is the poly-paradigm methodology. The article gives the description of interethnic and interconfessional relations in the Republic of Tatarstan in 2014-2016, the comparative data on the largest cities of the republic are given. A particular attention is paid to the analysis of migrant perception peculiarities by the local population. The materials of the article can be useful for ethnologists, social and cultural anthropologists, political scientists, as well as for the representatives of the bodies and structures responsible for the issues of interethnic interaction.peer-reviewe

The boundary integral theory for slow and rapid curved solid/liquid interfaces propagating into binary systems

The boundary integral method for propagating solid/liquid interfaces is detailed with allowance for the thermo-solutal Stefan-type models. Two types of mass transfer mechanisms corresponding to the local equilibrium (parabolic-type equation) and local non-equilibrium (hyperbolic-type equation) solidification conditions are considered. A unified integro-differential equation for the curved interface is derived. This equation contains the steady-state conditions of solidification as a special case. The boundary integral analysis demonstrates how to derive the quasi-stationary Ivantsov and Horvay–Cahn solutions that, respectively, define the paraboloidal and elliptical crystal shapes. In the limit of highest Péclet numbers, these quasi-stationary solutions describe the shape of the area around the dendritic tip in the form of a smooth sphere in the isotropic case and a deformed sphere along the directions of anisotropy strength in the anisotropic case. A thermo-solutal selection criterion of the quasi-stationary growth mode of dendrites which includes arbitrary Péclet numbers is obtained. To demonstrate the selection of patterns, computational modelling of the quasi-stationary growth of crystals in a binary mixture is carried out. © 2018 The Author(s) Published by the Royal Society.

Integrative Approach in Teaching English for Professional Purposes

The article discusses the need for an integrative approach in teaching Business English, aimed at forming and developing professional competencies of a future graduate in the field of management. The applied aspect of the integrative approach means implementing the principle of integration in all parts of the educational process. In this study, it concerns the formation of professional competencies during the process of learning a foreign language. The basis of the successful implementation of an integrative approach at all levels is adding a reflective component, forming of reflective position of a student. It helps analyze and order all the elements and stages of the studying activity from goal setting to result achieving; it also helps students realize themselves as active participants of the studying process. Today, due to various factors and reasons, the potential of the discipline “Business Foreign Language” in forming professional competencies often remains unrealized. The course developed allows to fully reveal its opportunities of forming professional competencies for a future manager. The course is focused on developing skills in a foreign language and professional training of students in such field of study as “Management”. This contributes to the students’ personal and professional growth. This is achieved due to the course’s content and structure, when the general concept of management and its functions being considered sequentially and logically. Including the reflective component into the studying process allows not only the teacher but also the students themselves follow the level of progress and the degree of achieving the goals set by them

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

Modern Imaging Techniques and Their Role in Contact Radiation Therapy (Brachytherapy) Planning

The paper considers an algorithm for the diagnostic study of patients with cancer of different localization, the possibility and feasibility of involving imaging techniques in radiation therapy and brachytherapy (BT) planning. The most widely used ultrasound in BT planning does not exclude a subjective assessment of the boundaries of the tumor and organs at risk, as well as the inaccuracies caused by endostatic devices. Magnetic resonance imaging (MRI) provides a high level of achievement of the criteria necessary for BT planning, but it has financial constraints and the need for individual selection of research conditions. Computed tomography (CT) is the most effective technique for visualizing the tumor, endostatic devices, and organs at risk for BT 3D planning. The involvement of MRI and positron emission tomography with CT in BT planning is a promising area that requires equipping with a mathematical tool for double and triple contouring of the tumor and organs at risk and for defining protection priorities. The prescribed and used focal dose should be controlled by direct dosimetry methods to ensure quality assurance

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
