Mathematical modeling of thermal stabilization of vertical wells on high performance computing systems

Temperature stabilization of oil and gas wells is used to ensure stability and prevent deformation of a subgrade estuary zone. In this work, we consider the numerical simulation of thermal stabilization using vertical seasonal freezing columns. A mathematical model of such problems is described by a time-dependent temperature equation with phase transitions from water to ice. The resulting equation is a standard nonlinear parabolic equation. Numerical implementation is based on the finite element method using the package Fenics. After standard purely implicit approximation in time and simple linearization, we obtain a system of linear algebraic equations. Because the size of freezing columns are substantially less than the size of the modeled area, we obtain mesh refinement near columns. Due to this, we get a large system of equations which are solved using high performance computing systems.Comment: 9 pages, 5 figure

Socially efficient entry barriers?

Stagnation of the Russian economy lends a new urgency to the question of whether reserves of competition incentives can be used to overcome the current negative economic tendencies. The lowering of entry barriers is traditionally considered a universal instrument of promoting competition. However, lower entry barriers can be mistakenly associated with bringing the market closer to the state of the so-called "perfect" competition. The authors aim to show that the absence of entry barriers does not improve competition in certain markets. On the contrary, it may result in a decrease in social welfare. This is particularly true of capital-intensive goods, for instance, large diameter pipes for gas pipelines. Lack of proper competition in such sectors of the market necessitates entry barriers, for they help to achieve a separating equilibrium at the market. Since there are costs associated with creating a separating equilibrium, it is necessary to assess both costs and benefits of the pooling and separating equilibria

Mode of Understanding the Terms "Concept" and "Folklore Concept" in Modern Humanities

The urgency of the study is explained by the importance of a thorough study of typology and classification of concepts in terms of modern cognitive linguistics, linguoculturology, history, ethnolinguistics, philosophy and psychology, including folklore concept as a set of signs that form a semiotic model of national and cultural experience and allow in-depth study of cultural processes in the light of historical and national factors. The aim of the article is to try to comprehend the concept and folklore concept from the standpoint of modern researchers working in various fields of humanities, to analyse, compare the main aspects of studying the problem, considering industry specific features. The main research method is a theoretical method that involves analysis, synthesis, generalisation of the theoretical basis on this topic, and the subject of study – the term concept as a tool of scientific analysis, mental construct and unit of consciousness. The article identifies the main structural and classification features of concepts, diversity of views on the problem of folklore concept from the standpoint of scholars from different fields of humanities and representatives of different cultural strata, the specific features of Ukrainian folklore are considered in detail on the example of texts of thoughts, historical songs, songs-chronicles, wedding songs, carols, Christmas carols, ballads. The materials presented in this paper will help to clarify the specific features and breadth of the mode of understanding certain cultural, folklore and historical phenomena at the intersection of various humanities and social sciences

Design and implementation of adaptive technology for teaching mathematics to school children based on integrated diagnostic approach to subject preparation and competence development

The development of school teaching  systems to enable effective adaptive communication of information requires specific pedagogical solutions to several important theoretical and methodological problems .These include 1) the discernment of basic characteristics needed to diagnose and improve the quality of subject preparation for schoolchildren, 2) clarifying the role of the teacher in the structure of adaptive learning  process, and  3) finding ways to integrate adaptive content into the framework of courses on mathematics. The purpose of our study was to determine theoretical and methodological foundations of teaching mathematics to schoolchildren taking into account their level of ability with the consequent development of appropriate adaptive content. The basic characteristics that underpin the concept of adaptive learning which contributes to both individual profiles of student ability to learn and subsequent success outcomes are: proficiency, motivation to learn and level of mathematical knowledge. The evaluation of individual profile structure of schoolchildren determines the choice of methodologies for presentation of adaptive content in ways allowing development and motivation. The system of educational process management developed in this way includes both content-methodical and procedural-technological components. This makes it possible to automatically evaluate the level of each students' mathematical training (knowledge, motivation, development) and to ensure continuous improvement. This system can also be used by secondary teachers of mathematics as a part of extracurricular activities, or as a distance learning support. In addition, the recommendations for structuring multi-level problem material can be used by mathematics teachers to self-construct adaptive sets tasks at various stages of teaching mathematics. As a result, students have the opportunity to improve their own profile of learning success, particularly by solving a chain of tasks

Cell wall functional activity and metal accumulation of halophytic plant species Plantago maritima and Triglochin maritima on the White Sea littoral zone (NW Russia)

The presented study supplements the knowledge on ion-exchange capacity, swelling capacity (elasticity) of the plant cell wall, and the accumulation of heavy metals in halophytic species Plantago maritima and Triglochin maritima in the tidal zone of the White Sea western coast. The littoral soils of the coastal territories are sandy or rocky-sandy, medium and slightly saline with poor content of organic substances, Mn, Zn, Ni, and Pb. Studied soils are considered as uncontaminated by heavy metals because they contain background amounts of Fe and Cu. Sea water is significantly polluted by Fe (3.8 MPC) and Ni (55 MPC), has poor content of Zn and Cu and background level of Pb and Mn. The coastal dominant plant species P. maritima and T. maritima were characterized by intensive metals accumulation which was reflected in the coefficient of biological absorption (CBA) of metal by a whole plant. For P. maritima the following metal accumulation series was obtained: Cu (3.29)> Zn (2.81)> Ni (1.57)> Pb (1.30)> Mn (1.21)> Fe (0.97), and for T. maritima: Ni (3.80)> Fe (2.08)> Cu (1.91)> Zn (1.84)> Pb (1.51)> Mn (1.31). Roots accumulated 50–70% of Ni, Cu, Zn, Pb and Mn of the total metal content in the plant while leaves and stems contained 30–50%. Fe was allocated mainly in the roots (80%). The ion-exchange capacity of the plant cell wall for P. maritima and T. maritima was established as follows correspondingly: 3570–3700 and 2710–3070 μmol g-1 dry cell weight per leaf; 2310–2350 and 1160–1250 μmol g-1 dry cell weight per root

Developing Databank as an Instrument for the Elder People Wellbeing Analysis

Recent researchers succeed in well-being measuring of elder people life.Russian scientists have to run after the leaders investigating the official statistics data and analyzing the trends of indices. Within the project in Evaluation and enhancement of social, economic and emotional wellbeing of older adults we designed the model of older generation well-being measuring and the database to calculate objective and subjective indices according to this model. This paper is focused on the database created to elder people well-being research. The information system' structure is subscribed. It is consisted of database and web-interface. Either the results of its application for elder people well-being assessing are presented. Using the information system we defined some trends in indices dynamics for Tomsk region at 2000 - 2013. We found the next results: the employed pensioners' number increases significantly, the rural pensioners number is declining. The elder people's availability for using IT grew from 5.56 per cent to 78 per cent of the respondents during 2007-2013. There is a positive dynamics in all analyzed social objects visiting availabilities for elder people. More than 80 per cent of respondents can visit medical clinic, department store, pharmacy and the bank office on foot. The social care and Pension Fund nearness is less

μ-Oxalato-bis­[(2,2′-bipyridyl)­copper(II)] bis(perchlorate) dimethyl­formamide disolvate monohydrate

The title compound, [Cu2(C2O4)(C10H8N2)4](ClO4)2·2C3H7NO·H2O, contains doubly charged centrosymmetric dinuclear oxalato-bridged copper(II) complex cations, perchlorate anions, and DMF and water solvate mol­ecules. In the complex cation, the oxalate ligand is coordinated in a bis-bidentate bridging mode to the Cu atoms. Each Cu atom has a distorted tetra­gonal-bipyramidal environment, being coordinated by two N atoms of the two chelating bipy ligands and two O atoms of the doubly deprotonated oxalate anion. Pairs of perchlorate anions and water mol­ecules are linked into recta­ngles by O—H⋯O bonds in which the perchlorate O atoms act as acceptors and the water mol­ecules as donors. Methyl groups of the DMF solvent molecule are disordered over two sites with occupancies of 0.453 (7):0.547 (7), and the water molecule is half-occupied
