The formation of M. V. Lomonosov personality is specified due to the peculiarities of the socio-cultural environment of the Russian North. The scientific heritage of the first Russian academician has tragic history and fate. His people’s memory was kept by progressive figures of the region, the priests, who suggested the need to explore the heritage and the biography of the scientist and raise up a monument to him in Arkhangelsk. A significant role in commemoration and exploring the scientific heritage of Lomonosov had his anniversaries: 1865, 1911, 1961, 1986, 2011. The paper first examines the history of popular initiatives of northerners to commemorate the first Russian academician - M. V. Lomonosov. On the basis of historical materials such selfless initiatives as: the perpetuation of the scientist’s name; educational initiatives; support for young people seeking education and science; strategic initiatives are compiled. The article presents, in chronological order, their various forms: fundraising money for scientist monuments; promotion of Lomonosov awards and scholarships; organization of Lomonosov readings; creation of Lomonosov Fund; the formation of the Arkhangelsk region as the university center, etc. The author shows the development of Lomonosov movement in the region as a popular initiative. The paper reveals the perspective popular initiative to create at Lomonosov homeland the historical, cultural and scientific complex “Lomonosov manor”, which branches may be placed in the different areas of the region. © 2017, Butorina T.

The energy lost by fast structural ions in collisions with atoms has been estimated based on the eikonal approximation. Structural ions are ions that consist of a nucleus and a number of its related electrons. It has been shown that taking account of interaction between the ion nucleus and an atom of the target in the eikonal approximation may considerably influence the effective stopping of the ion due to the excitation of its electron shells. © 2017, Pleiades Publishing, Ltd.

At present, the sources of entangled photons have a low rate of photon generation. This limitation is a key component of quantum informatics for the realization of such functions as linear quantum computation and quantum teleportation. In this paper, we propose a method for high intensity generation of entangled photons in a two-mode electromagnetic field. On the basis of exact solutions of the Schrödinger equation, when electrons interact in an atom with a strong two-mode electromagnetic field, it is shown that there may be large quantum entanglement between photons. The quantum entanglement is analyzed on the basis of the Schmidt parameter. It is shown that the Schmidt parameter can reach very high values depending on the choice of characteristics of the two-mode fields. We find the Wigner function for the considered case. Violation of Bell's inequalities for continuous variables is demonstrated. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA.

The moments in the theory of deceleration of fast charged particles colliding with an oscillator have been considered in the dipole approximation. In this approximation, the problem has been solved exactly, and the moment of the oscillator has been determined from the initial state |m> = |0> in the form of the sum of 1D integrals. The method considered here makes it possible to calculate the moments for ion velocities close to atomic velocities (v ~ va). © 2016, Pleiades Publishing, Ltd.

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 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.
