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. Source

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 of fast charged particles colliding with an oscillator is considered in the dipole approximation. In this approximation, the problem is solved exactly and the energy loss of the oscillator from the initial state |m〉 = |0〉 is found in the form of the sum of single integrals. It is shown that passing to the limit, the Bethe theory for an atom with small perturbations can be obtained, and in the case of strong fields, the correction to the Bethe theory, analogous to the Bloch correction, can be calculated; in addition, a classical limit coinciding with the Bohr formula is possible. © 2015, Pleiades Publishing, Ltd.

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. Source

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. Source
