Аннотация: This article is devoted to the study of codependence as sociopsychological factor that affects the personality characteristics of coaddicts. Codependence is regarded as a persistent state of insuperable, often painful, dependency, based on relationships with a significant person who suffers from one type of dependence. A distinctive feature of codependence is selfdestructive attachment to a substancedependent substance, accompanied by specific emotional, psychological and behavioral manifestations. To conduct the study codependence as sociopsychological factor that affects the personality characteristics of coaddicts, an applied research was conducted. Object of the study: codependent mothers whose relatives suffer from any kind of dependence. The subject of the study: sociopsychological characteristics of codependence. The purpose of the study: the study of socio psychological characteristics of codependence and its influence on the peculiarities of the occurrence of addictions in the family. 1. Constructivedestructive family (KDS) (E.G. Eidemiller, VV Yustitsky). 2. Methods for determining codependence D. Fisher, adapted by V.D. Moskalenko. 3. IStructural Test of Ammon (ISTA). According to the results of the study, the existence of a relationship between codependence and manifestations of mental states (frustration, aggression, anxiety). In addition, the study showed that destructivedeficit functions predominate in the structure of the personality of coaddicts, which indicates a «contact breakage», i.e. on the severance of relations with himself, with other people, with the world around him

Аннотация: This work is devoted to the study of centrifugation processes, which are one of the most complexprocesses of technology. The use of the action of the centrifugal force field for the separationof heterogeneous liquid systems in a rotor system (centrifuge) is very effective. Separability ofcentrifuged materials, multiphase dispersion, the relationship between phases cause ambiguousprocesses of centrifugation, and therefore it is not always possible to accurately predict and evaluatethe main characteristics of the separation of heterogeneous systems in the centrifugal force field.For a qualitative assessment of the main separation characteristics, such as the angular velocityof rotation, the dependence of the angles of inclination of the glasses on the angular velocity, thesettling time of particles, etc., is created a mathematical model of the vertical rotor system. Therotor represents a round disk on which cups (vial) with a multiphase liquid are symmetricallysuspended. A particular case of a fixed rotor is considered. Nonlinear differential equations ofmotion of the suspension particle, which have no exact solution, are obtained. The research isconducted by analytical and numerical methods. The dependence of the slope angles of the tubesfrom the angular rotational speed of the rotor, sedimentation curves are obtained , which allowestimating the time of particle deposition and the effect of the particle size distribution on theseparation process. The results of this research work allow us to determine with sufficient accuracyall the necessary characteristics of the sedimentation working process, and also, in certain cases,it is possible to exclude the conduct of experimental work. The results of the work confirm thephysical meaning of the process, which can serve as a justification for the use and introduction ofthis mathematical model in industrial production.

Аннотация: The links of high-speed mechanisms and manipulators are deformed under the action of inertiaforces and external loads. These deformations have significantly influence on the accuracy of execu-tion of the required law of motion by the operating point of the mechanism and the positioning ofthe manipulator grip. Accordingly, longitudinal and transverse displacements, angles of rotation ofcross-sections of links under the action of distributed dynamic and external loads are investigatedin this paper. The developed technique allows defining deformations of links of mechanisms andmanipulators and can be applied at their designing. To determine the transverse displacements,the angles of rotation of the cross-sections of the links – the basic differential equation of the elasticline of the beam, to determine the longitudinal displacements of the points of the links – Hooke’slaw and the boundary conditions of the computed scheme of the investigated linkages for elasticcomputation are used. The bending moment in the basic differential equation of the elastic line ofthe beam and the longitudinal force in Hooke’s law were determined by the theory developed bythe authors of the analytical definition of internal forces in the links of planar linkages with stat-ically determinate structures, taking into account the distributed dynamic loads from the massesof links, dead weight and from the acting external loads. According to the developed technique,programs are created in the MAPLE system and animations of the movement of mechanisms arereceived, with the construction on the links the diagrams of transverse, longitudinal displacementsand angles of rotation of the link cross-sections. The developed analytical technique for determin-ing deformations in the cross-sections of links is used to calculate the strength and stiffness ofelements of movable linkages.

Аннотация: This paper is devoted to a numerical study of defining of parameters of dynamical systems arisingin financial and economic problems. The importance of parameters that are difficult to measure isgreat, so defining them will help to make forecasts and a work plan for the future at the govern-mental level. An effective way to restore parameters is to solve the inverse problem. The methodof coefficient recovery using the algorithm of differential evolution, which was proposed by RainerStorn and Kenneth Price, is presented in this paper. On the example of solving the direct prob-lem of the mathematical model of neoclassical economic growth of Robert Solow and the resultsobtained, the inverse problem was solved and unknown parameters were determined. The Solowmodel is based on the Cobb-Douglas production function, taking into account labor, capital andexogenous neutral technical progress. Also, for further calculations, the economic model proposedby Mankiw-Romer-Weil based on the Solow model was considered, but with the addition of hu-man capital, where the number of variables and coefficients that need to be restored has alreadyincreasing. A direct problem was also solved, results were obtained that were applied in the algo-rithm of differential evolution for parameters recovery.

computational grid construction algorithm -- unstructured mesh -- adaptive mesh -- differential elliptic equations -- reversed Beltrami equation
Аннотация: Adaptive generation of computational grids can improve the efficiency of mathematical model-ing by increasing the accuracy of numerical approximations. The paper describes a method forconstructing unstructured grids with adaptation based on differential methods. The applicationof these methods ensures a smooth distribution of the geometric characteristics of the grid, i.e.the appearance of adjacent cells that differ greatly in size and shape becomes unlikely. To achieveproper adaptation in unstructured grids we use the novel approach based on methodology of adap-tive structured grid construction. This approach uses the method of grid construction based onsolving inverted Beltrami equation to create mapping of some sample grid domain to the physicalarea. This mapping is used to construct point set on which the unstructured grid is constructedusing Delaunay triangulation method. Thus, the result is unstructured grid with proper adapta-tion. Adding fault and fractures or other structure elements may be supported by implementingconstrained Delaunay triangulation.

Аннотация: The article analyzes modern problems and trends of development of the system of higher education. The persistent expansion of regulation and uncontrolled growth of bureaucracy increase dependence of regulated areas on private interests of those who have access to the regulatory machine. This tendency has not bypassed the academic sphere, and, in many instances, there is a clear discrepancy between the proclaimed objectives and observed results. The vivid example is the Russian system of higher education, which is the main focus of the present study. We explain this phenomenon through the lens of the institutional corruption theory and argue that the observing evolution of modern academia forms a wrong system of incentives, bringing to the hands of bureaucrats excessive power, which, eventually, distorts the performance of the higher education sphere and undermines the effectiveness of this important institution.

В данной работе предложен простой универсальный метод для определения бродифакума, бромадиолона и дифенакума в твердых брикетах, которые представляют собой смесь парафина, яда и наполнителя, в качестве которого могут быть использованы зерно, мука и тому подобное. Сложность в анализе приманок, содержащих парафин, заключается в том, чтобы от него избавиться. Для этого мы предлагаем использовать экстракцию в системе гексан-ацетонитрил. Парафин растворяется в гексане, в то время как бродифакум, бромадиолон и дифенакум – нет. Образующуюся двухфазную систему разделяли с помощью делительной воронки и собирали нижнюю фракцию. При наличии в пробе каких-либо наполнителей их отфильтровывали до разделения смеси, остаток промывали ацетонитрилом. Перед вводом пробы в хроматограф ее дважды фильтровали с помощью PTFE-фильтров пористостью 0,45 мкм. Наилучшее разделение компонентов смеси было достигнуто при использовании колонки Thermo Acclaim® Surfactant в качестве подвижной фазы был взят ацетонитрил и 0,1 М водный раствор ацетата аммония (рН 5,4) в режиме градиентного элюирования. Детектирование всех трех ядов проводили при длине волны 264 нм. Данный метод обладает чувствительностью 0,028 мг. Диапазон линейности от 0,00067 до 0,01 %. Коэффициент извлечения для бромадиолона составляет – 94 %, для бродифакума – 98 %, для дифенакума – 90 %.
