About Grid Generation in Constructions Bounded by the Surfaces of Revolution

For constructions bounded by the surfaces of revolution, structured grid generation technique is presented. Its technology has been elaborated within the variational approach for constructing optimal grids satisfying optimality criteria: Closeness of grids to uniform ones, closeness of grids to orthogonal ones and adaptation to a given function. Grid generation has been designed for numerical solution of the differential equations modeling the vortex processes of multi-component hydrodynamics. In the technology, the three-dimensional construction in which it is required to construct a grid is represented in the form of the curvilinear hexahedron defining its configuration. The specific feature of the required configurations is that some faces of a curvilinear hexahedron lie in one plane and along edges of adjoining faces grid cells degenerate into prisms. Grid generation in the considered constructions has started to be developed by the elaboration of algorithms for the volume of revolution which has become the basic construction. The basic construction is obtained by the rotation through 180° around the axis of a generatrix consisting of straight line segments, arcs of circles and ellipses. Then the deformed volumes of revolutions are considered along with the generalizations of the volume of revolution which represent constructions obtained by the surfaces of revolution with parallel axis of rotation. The aim of the further development of the technology is to consider more and more complicated constructions and elaborate the technology for them. In the presentation, the current state of the development of the technology is given. Examples of generated grids are supplied. © 2021 Institute of Physics Publishing. All rights reserved

Neurotic states at students with a hypodynamia

Mental health of the person depends on his physical state. Need of sports exists throughout human life. Restriction of motor activity of a body, lack of physical exercises negatively influences both physical health, and the mental healthПсихическое здоровье человека зависит от его физического состояния. Необходимость занятия спортом существует на протяжении жизни человека. Ограничение моторной деятельности тела, недостаток физических упражнений отрицательно влияет как на физическое здоровье, так и на психическо

Cardio-and Neuroprotective Effects of Corvitin and 2-Oxoglutarate in Rats with Pituitrin-Isoproterenol-Induced Myocardial Damage

Heart diseases, especially acute coronary syndrome (ACS), are among the most severe illnesses that often lead to death. Despitesignificant advances in the prevention and treatment of ACS, the incidence of the disease and its complications are very serious. +eimbalance between pro- and antioxidant systems, the formation of active carbonyl compounds, and the end products of glycation inthe blood and tissues are the key moments in the development of heart and neurological disorders leading to a change of behavioralresponses. So, the search for antioxidants with cardio- and neuroprotective effects is an urgent task. +is study was aimed atevaluating the effects of Corvitin and 2-oxoglutarate on physiological parameters, heart histology, and markers of carbonyl/oxidativestress of rats with pituitrin-isoproterenol-induced myocardial damage (PIMD). Increased sweating, tachycardia, significantly decreasedlocomotor and exploratory activity, changes of ECG, heart histology, and biochemical changes were observed in the PIMDgroup.+e administration of Corvitin or 2-OG led to the recovery of locomotor and cognitive activities of the rats, improvement inheart histology, a decrease in the levels of thiobarbituric acid reactive substances, advanced glycated end products, and variouschanges in the activity of the antioxidant enzymes, 6 days after PIMD. So, Corvitin and exogenous 2-OG show cardio- andneuroprotective effects through the decrease of carbonyl/oxidative stress and regulation of the activity of the antioxidant system

The algorithm for generation of structured grids in deformed volumes of revolution

For the volume of revolution deformed by another volume of revolution, a grid generation algorithm is suggested. The algorithm is designed for multimaterial hydrodynamic simulation and for solving other physical and engineering problems. The algorithm represents the non-stationary procedure generating three-dimensional structured grids in domains with moving boundaries. The algorithm is developed within the variational approach for constructing optimal curvilinear grids. The volume of revolution is obtained by the rotation about the axis through 180° of a plane generatrix curve consisting of straight line segments and arcs of circles. The non-stationary algorithm is the iterative process at each stage of which the deformation of a grid and then its optimization are carried out. The deformation of a grid is implemented within the geometrical approach, and the optimization of a grid within the variational approach. Iterations are continued until the necessary deformation is reached. The algorithm is realized in the computer code written in C++. © Published under licence by IOP Publishing Ltd

Modern Means of Personal Protection of People from Bloodsucking Arthropods

The review focuses on the means of personal protection of people from blood-sucking arthropods, mainly from Ixodidae ticks. Individual (personal) protection of humans is an important component of nonspecific prevention of natural-focal vector-borne diseases. The paper considers statistical data describing the level of significance and relevance of the information about the infections transmitted by ticks, for instance, tick-borne viral encephalitis, tick-borne borreliosis etc. Presented are the characteristics of different groups of personal protection means: insectoacaricidal, repellent, and insectoacaricidal-repellent ones. Indicators of their effectiveness are assessed; their practical use, as well as the features of special protective clothing and the necessity of its application is described. The toxicity of protective clothing is reduced through a lining fabric, local inserts of fabric with insectoacaricidal impregnation and the use of underwear. Different interpretation of the term “repellent” in the domestic and foreign literature, and also two different approaches (“Eastern” and “Western”) to the design and manufacture of personal protection means for people against attacks of blood-sucking arthropods, including Ixodidae ticks, in Russia and Western Europe countries and the USA is discussed. The paper highlights the effect of different pyrethroid groups on the behavioral reactions of ticks. It is shown that in the Russian Federation the use of permethrin is prohibited for the treatment of protective clothing against blood-sucking arthropods, in particular against the taiga tick Ixodes persulcatus, which is the main vector of dangerous infections across the major part of the country (in the east of the European part, the Urals, Siberia and the Far East)
