The article presents the results of the study of interhemispheric asymmetry among 28 men and 33 women of the elderly age. Interhemispheric asymmetry was assessed by DC-potential level difference between symmetrical areas of the brain. The DC-potential were recorded, processed and analyzed using a 12-channel hardware and software diagnostic complex "Neuroenergometr -KM in the unipolar leads. The resulting distribution characteristics DC-potential were compared with the average standard values for the corresponding age period incorporated into the complex software. It was revealed that interhemispheric interaction among the elderly living in the North was changed in comparison with normative data that is expressed in the individual variability of the hemispheric differences in the group of men and women. Smoothing hemispheric asymmetry was observed among men living in the North in the frontal leads and among women in central ones and hemispheric dominance in the central leads of men. In both groups, there is left-hemisphere dominance in the parietal and frontal leads of women.

The article presents the results of studies of the behavioral response in 53 elderly people (60-65 years of age). The purpose of the study is to compare physiological parameters of a behavioral response in men and women in old age. Indicators of decision-making strategies in a free, probabilistic and deterministic environments were assessed through a computer complex for psychophysiological researches KPFK-99 «PSIHOMAT», which includes a test computer system «Binatest». It was found that older people behavior strategy in a free environment has the character of a random search. Stereotype of choice, which is important to adapt to changing environmental conditions and to organize complex behavioral programs, is typical for men between the age of 60-65. Manifestation of impulsivity, as well as lower rates of operations thinking when analyzing the situation and making the right decision, indicating incomplete digestion of probabilistic structure are seen in women between the age of 60-65. In a deterministic environment, when increasing the rate of activity, there was a decrease of accuracy of the assignment in men. It is noted that in tasks where you need to quickly perceive the details and often switch attention, women show greater efficiency.

The issue of atmospheric air pollution in the Arctic is of global nature and concerns the entire humanity. The fragile nature of high latitudes is extremely vulnerable to human impacts. The negative effects are caused not only by plants and factories located in the northern latitudes but also by far away plants in Central Europe, America, and Asia. As a result, pollutants migrating to the Arctic significantly affect the environmental situation in the northern regions of the planet. In order to improve the environmental situation in the Arctic, environment quality has to be managed properly in all regions of the world. This article is focused on the analysis of the situation in the Arctic region of Russia, namely in the North of the Russian Plain. Starting from the 1980's, Russia has conducted environmental monitoring of the snow cover to determine critical pollutant loads on natural ecosystems across the country. A large amount of data has been accumulated allowing to carry out an in-depth analysis of the pollution of atmospheric precipitations and snow cover with acid-forming compounds. This article summarizes the results of research conducted from 1982 to 2013, including: 1) pollutant emission trends compared to available atmospheric air monitoring data, 2) spatial distribution of acidified precipitation occurrences, 3) neutralization probability, 4) calculation of sulphur deposition loads compared to the reference values proposed as critical loads by the European Monitoring and Evaluation Program (EMEP). © 2015, Olga Trubitsina.

Energy loss straggling of fast charged particles colliding with atoms have been considered in the eikonal approximation. The result is represented in the form of the Fano formula with a nonperturbative correction. The known nonperturbative Titeica formula (which is transformed to the Fano formula when perturbation theory is applicable) is obtained only under certain approximations in eikonal calculations. It has been shown that straggling calculated with allowance for nonperturbative effects at large charges of the projectile can be significantly different (by an order of magnitude) from the results obtained by Titeica, Fano, and Bohr. Energy loss straggling of fast highly charged ions on hydrogen and copper atoms have been calculated. The latter results are compared to experimental data. © 2012 Pleiades Publishing, Ltd.

The processes of reemission of attosecond electromagnetic pulses by systems in nonstationary states have been considered. The probabilities of the reemission of attosecond electromagnetic pulses at the resonance charge exchange of a proton on a hydrogen atom and at the decay of a quasistationary state, as well as the probabilities of the reemission of attosecond pulses by a system in a resonance external field, have been calculated as examples. The developed method can be applied to more complex targets, including targets in the collision state, and to various chemical reactions. © 2014 Pleiades Publishing, Inc.

The processes of reemission of ultrashort electromagnetic pulses by linear chains consisting of isolated multielectron atoms have been considered. The developed method makes it possible to accurately take into account the spatial inhomogeneity of the field of an ultrashort pulse and the momenta of photons in reemission processes. The angular distributions of reemission spectra have been obtained for an arbitrary number of atoms in a chain. It has been shown that the interference of the photon emission amplitudes leads to the appearance of characteristic "diffraction" maxima. The results allow standard generalization to the cases of rescattering from two-dimensional (graphene-like) and three-dimensional lattices, as well as to the case of the inclusion of thermal vibrations of the atoms of lattices. © 2012 Pleiades Publishing, Ltd.

A theory of the reradiation of ultrashort electromagnetic pulses by arbitrary polyatomic systems of isolated complex atoms has been developed. The technique used allows the spatial inhomogeneity of the field of an ultrashort pulse and photon momenta in reradiation processes to be accurately taken into account. The angular distributions of the reradiation spectra have been obtained for an arbitrary number of atoms in the system. The processes of interference between the photon emission amplitudes are shown to give rise to characteristic "diffraction" maxima. We consider one-dimensional, two-dimensional, and three-dimensional rectangular lattices as examples as well as planar and cylindrical structures as models of planar nanosystems and nanotubes. © 2013 Pleiades Publishing, Inc.

The paper represents new results of structural-semiotic analysis on syntactics, semantics and pragmatics of ritual-mythological «texts», which are included in subject-problem field of traditional mental ecology and sacred ethnomedicine of peoples living in the European North of Russia. The main purposes of the paper are investigation of ritual process of sacred space’ creation (hierotopy) of temples built for one day in the North of Russia, revelation of «healing» («saving») mythopoetic semantics of the phenomenon of «one-day» temples building within folklore-ethnographical discourse, church archaeology and Russian religious-philosophical knowledge. Data base of the investigation is composed with «rituals of disasters», related with menace of epidemics, epizooties, social and natural cataclysms. Subject field of them may be determined as «ritual medicine of catastrophes». The main attention is paid to investigation of ritual technologies of sacred space’ creation (hierotopies) within the process of one-day building of votive wonder-working temples on the Russian North. The motivation analysis of ritual one-day technologies reveals their relation to crisis, marginal situations, «troublous times», when all foundations of the universe is being destructed and chthonic forces of unhuman world, bearing diseases and death, bad harvest and famine, fires and natural disasters are rushing into human world. Special occasional rites (as sort of «ritual medicine of catastrophes») were performed to restrain the forces of chaos. Building of one-day temples was considered to be the most important technology of renovation of the universe. © 2016, Springer New York LLC. All rights reserved.

The paper shows the study results of a brain electrobiological activity in elderly women with various level of cognitive impairment. Importance of early diagnostic of cognitive disorders and applicability of methods of functional brain imaging in revealing disorders in higher cortical functions are shown in the paper. To assess cognitive functions we applied express-method of evaluating of cognitive functions during normal aging. According to the test results three groups were formed: 1 - women without cognitive disorders, 2 - with mild cognitive impairment, and 3 - with moderate cognitive impairment. The EEG was registered for all participants by means of 128-channel system GES-300. Absolute spectral power for all bands was calculated. According to the spectral analysis it has been revealed that higher power of the slow-wave rhythms is characteristic of groups with disorders of cognitive functions. Prevalence of a delta rhythm in the general EEG has been also stated. These changes are perhaps caused by dysfunction of the activating cholinergic systems and cortical structures, and also both dyscirculatory and structural changes of brain matter. © 2016, Springer New York LLC.
