ИНТЕГРАТИВНЫЕ ОСНОВЫ АЛЕКСИТИМИИ

The aim of the study was to show the interrelation between the gradually increasing alexithymia traits and the integrative self regulation style of emotional, personal and cognitive interaction with the environment. The Toronto Alexithymia scale was used for examination of 356 students of a medical university. The students were divided into 4 groups in accordance with the alexithymia degree (69 - 94 scores for a high degree). The integral methods of estimation of an individuality were: Temperament Traits Accentuation, Differential estimation of Personal anxiety, Property Concept Discrimination and Copying Strategy. We noticed that the higher was the alexithymia degree the more marked was accentuation of asthenic temperament traits (emotional instability, social and objective passivity) and of personal anxiety (neural-psychic excitability and shyness). There was prevalence of inadaptive copying strategies and abstractive self-controlling style of intellectual activity. Alexithymia is the integral psychological phenomenon combining emotional, volutional, personal and mental parameters of an individuality as a whole. The structure of the phenomenon allows existence of different variants of the components and hence of its typology - the fact of scientific and practical value.Цель работы: выявить взаимоотношения между нарастающими градациями алекситимии и интегральными параметрами индивидуальности, проявляющимися в стиле саморегуляции эмоционального, личностного и когнитивного взаимодействия с реальностью. 356 студентов медицинского университета оценивали по Торонтской шкале алекситимии и разделили на 4 группы по степени ее выраженности, при высокой с числом баллов 69 - 94. Применены интегральные методы исследования индивидуальности - тесты акцентуации свойств темперамента, дифференцированной оценки личностной тревожности, дискриминации свойств понятий и определения копинг-стратегий. Установлено, что чем выше степень алекситимии, тем больше выражена акцентуация астенических свойств темперамента (эмоциональная нестабильность, социальная и предметная пассивность), а также уровень личностной тревожности (особенно факторов нервно-психической возбудимости и застенчивости в ее структуре). Отмечено также нарастание числа неадаптивных копинг-стратегий и предпочтение абстрактного стиля саморегуляции интеллектуальной деятельности. Алекситимия - интегральный психологический феномен, сопрягающий эмоционально-волевые, личностные, ментальные параметры индивидуальности в единое целое. В структуре этого феномена можно предполагать существование различных вариантов соотношения компонентов и, следовательно, его типологии, что может иметь научное и практическое значение

Hippocampal neurogenesis in the new model of global cerebral ischemia

The study aimed to evaluate the changes of hippocampal neurogenesis in a new model of global transient cerebral ischemia which was performed by the occlusion of the three main vessels (tr. brachiocephalicus, a. subclavia sinistra, and a. carotis communis sinistra) branching from the aortic arch and supplying the brain. Global transitory cerebral ischemia was modeled on male rats (weight = 250–300 g) under chloral hydrate with artificial lung ventilation. Animals after the same surgical operation without vessel occlusion served as sham-operated controls. The number of DCX-positive (doublecortin, the marker of immature neurons) cells in dentate gyrus (DG) and CA1-CA3 fields of hippocampus was counted at the 31st day after ischemia modeling. It was revealed that global cerebral ischemia decreased neurogenesis in dentate gyrus in comparison with the sham-operated group (P<0.05) while neurogenesis in CA1-CA3 fields was increased as compared to the control (P<0.05)

Study of the Hydrocarbon-oxidizing Activity of Bacteria of the Genera Pseudomonas and Rhodococcus

The selective activity of hydrocarbon-oxidizing microorganisms with regard to the degradation of alkanes, cycloalkanes, arenes was presented. The hydrocarbon-oxidizing activity of microorganisms of the genera Rhodococcus and Pseudomonas such as heptane, cyclohexane, toluene within the hydrocarbons destruction was determined. The growth rate for various hydrocarbons differs. Thus, the average specific growth rate of hydrocarbon-oxidizing microorganism (HOM) of the genus Rhodococcus is twice more than these substrates

Anomalous Behavior near T_c and Synchronization of Andreev Reflection in Two-Dimensional Arrays of SNS Junctions

We have investigated low-temperature transport properties of two-dimensional arrays of superconductor--normal-metal--superconductor (SNS) junctions. It has been found that in two-dimensional arrays of SNS junctions (i) a change in the energy spectrum within an interval of the order of the Thouless energy is observed even when the thermal broadening far exceeds the Thouless energy for a single SNS junction; (ii) the manifestation of the subharmonic energy gap structure (SGS) with high harmonic numbers is possible even if the energy relaxation length is smaller than that required for the realization of a multiple Andreev reflection in a single SNS junction. These results point to the synchronization of a great number of SNS junctions. A mechanism of the SGS origin in two-dimensional arrays of SNS junctions, involving the processes of conventional and crossed Andreev reflection, is proposed.Comment: 5 pages, 5 figure

Resource-efficient methods for predicting and selecting heat-resistant alloys

The power plant resource efficiency is largely dependent on heat-resistant alloys and is limited by the standard turbine operating temperature, which is slightly greater than 1000°C. These temperature limits are dependent on the characteristics of the heat-resistant alloys used in power plants. The current research aimed to discover new heat-resistant alloys using computer-based models to simulate the various properties of such materials. The first-principle methods were initially used in this study. These methods can determine the most important properties of alloys with a high degree of accuracy. This study presented an overview of the software used for first-principle simulation. Using RuAl as the demonstration alloy in this study, we provided step-by-step instructions on how to effectively study the properties of the heat-resistant alloys. Using the first-principle methods, the phonon spectrum and density of the phonon states of B2 RuAl were assessed. We use the parameters of the phonon spectrum to calculate the Grьneisen constant, volume coefficient of thermal expansion, Debye temperature, and temperature dependence of the heat capacity to estimate the melting temperature. Based on the RuAl alloy, the bulk moduli of the elasticity and equilibrium values of lattice parameters were calculated. The simulated results showed good agreement with the experimental data. The calculated parameters of RuAl were compared with those of the NiAl heat-resistant alloy. Using these results, we presented a method for selecting an alloy based on the replacement of ruthenium with nickel in the RuAl alloy. Selection was performed by analyzing the bulk modulus of elasticity and the electron structure of the Ru(Ni)Al alloy

Observational Evidence for the Associated Formation of Blobs and Raining Inflows in the Solar Corona

The origin of the slow solar wind is still a topic of much debate. The continual emergence of small transient structures from helmet streamers is thought to constitute one of the main sources of the slow wind. Determining the height at which these transients are released is an important factor in determining the conditions under which the slow solar wind forms. To this end, we have carried out a multipoint analysis of small transient structures released from a north-south tilted helmet streamer into the slow solar wind over a broad range of position angles during Carrington Rotation 2137. Combining the remote-sensing observations taken by the Solar-TErrestrial RElations Observatory (STEREO) mission with coronagraphic observations from the SOlar and Heliospheric Observatory (SOHO) spacecraft, we show that the release of such small transient structures (often called blobs), which subsequently move away from the Sun, is associated with the concomitant formation of transient structures collapsing back toward the Sun; the latter have been referred to by previous authors as "raining inflows." This is the first direct association between outflowing blobs and raining inflows, which locates the formation of blobs above the helmet streamers and gives strong support that the blobs are released by magnetic reconnection.Peer reviewe

Proximity effects and Andreev reflection in mesoscopic SNS junction with perfect NS interfaces

Low temperature transport measurements on superconducting film - normal metal wire - superconducting film (SNS) junctions fabricated on the basis of 6 nm thick superconducting polycrystalline PtSi films are reported. The structures with the normal metal wires of two different lengths L=1.5 $\mu$m and L=6$\mu$m and the same widths W=0.3$\mu$m are studied. Zero bias resistance dip related to pair current proximity effect is observed for all junctions whereas the subharmonic energy gap structure originating from phase coherent multiple Andreev reflections have occurs only in the SNS junctions with short wires.Comment: ReVTex, 4 pages, 4 eps figures include
