Study of human skin radiation in the terahertz frequency range
The radiation of human skin in the terahertz frequency range under the influence of mental stresses has been studied in the current work. An experimental setup for observation of changes in human skin radiation, which occur under the influence of psychological stresses, by means of a superconducting integrated receiver has been developed. More than 30 volunteers participate in these studies, which allows us to verify presence of correlation between the signals from the superconducting integrated terahertz receiver and other sensors that monitor human mental stress.
Objectives. Arterial blood pressure and serum blood glucose concentration, and the level of anxiety, as determined by the Spielberger test, as physical and psychological markers of stress under “modernization”, were studied in groups of native Siberians: the Khanty and the Mansi.
Results. The fraction of respondents with a high level of anxiety is 64% of the total sample. The average values of systolic and diastolic blood pressure are higher among natives living in large than in small “national” settlements (p<0.05). The arterial blood pressure of town dwellers is even higher. The same patterns are seen in the blood serum glucose concentrations in female samples. The average arterial blood pressure (in males and females) and the blood serum glucose concentration (in females) increases as people diverge from “traditional” lifestyles.
Conclusions. The results demonstrate that “modernization” and urbanization have a serious stressing influence on the aborigines of North Siberia.
The monograph is devoted to the assessment of population health indicators and comprehensive analysis of the factors influencing on the health of indigenous people of Russian North.
The article deals with the emotional burnout syndrome as a problem of personality psychology despite the tradition in Russian psychology to regard it as a result of continuous professional stress and professional deformation. Basing on the analysis of different approached to emotional burnout problem in Russian and foreign works it was concluded that they lack explanatory potential and there is a demand for investigating this syndrome in a broader paradigm. The author provides systemic methodological outlook of the problem and defines its theoretical status. Syndrome of emotional burnout is treated as violation of value-meaning personal regulation that hampers experiencing of higher order values and leads to dissolution of meanings in practical and professional activities. This approach proves promising for explanation of the specific nature of this syndrome as well as for elaboration of preventive measures.

The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
