Electromagnetic Radiation Influence on the Transversal Conductivity of the Graphene Superlattice
The transversal conductivity of the graphene superlattice under electromagnetic radiation and constant
electric field applied along the superlattice axis was calculated. The cases of sinusoidal and cnoidal
electromagnetic waves are considered. Conductivity dependences on the electromagnetic wave amplitude
and on the longitudinal electric field intensity were investigated. Such dependences were shown to have
the character of oscillations.

Electron States and Quasienergy Spectrum of the Graphene Exposed to the Electromagnetic Wave
The effective spectrum and wave functions of electron states in graphene under the electromagnetic wave with circular polarization are found. The band gap in the graphene spectrum induced by the electromagnetic wave is calculated. Occurrence of such gap is shown to have the nature of the parametric resonance. The effective energy of the electron state in graphene is proved to be the energy averaged over the period of the electromagnetic wave.

Effect of high-frequency laser radiation on the graphene current-voltage characteristic
The effective spectrum of electron states of graphene taking into account the action of high-frequency
laser radiation with elliptical polarization was calculated. Band gap was shown to arise in the graphene
spectrum in conditions of high-frequency electromagnetic wave. The current-voltage characteristic of the
graphene exposed to such radiation was studied. Effect of high-frequency electric field on the electron
magnetotransport in graphene was discussed
Emotional Personality Characteristics of Patients Diagnosed with Meningioma with Severe Post-Traumatic Stress
The results of the study on post-traumatic stress rates and individual indicators arising in response to the diagnosis of a life-threatening disease are being analyzed. The participants of the study are the patients of Burdenko National Medical Research Center of Neurosurgery, Ministry of Health of the Russian Federation (n = 25) diagnosed with meningioma. It has been shown that one of the psychological consequences of the diagnosis of “meningioma” is post-traumatic stress of different intensity rates. Increased depression, shyness and emotional lability are associated with high post-traumatic stress rates. The comparison of the triad of emotional-personal characteristics, social support indicators (according to the Psychological Safety Questionnaire) and basic assumptions (according to the World Assumptions Scale) made it possible to verify the research hypothesis. It has been revealed that high rates on depression and shyness scales (according to the Freiburg Personality Inventory) do not reflect the tendency to avoid social contact, but indirectly indicate the presence of auto-aggression or introverted orientation directed to oneself in people diagnosed with this disease

ASSESSMENT OF STRESS RESISTANCE OF EMPLOYEES OF THE CONSTRUCTION INDUSTRY IN THE ARCTIC CONDITIONS OF NORILSK
Proceedings of the XXV ISUF International Conference “Urban Form and Social Context: from Traditions to Newest Demands” (Krasnoyarsk, July 5–9, 2018)The list of professions engaged in the chain of construction activities includes a wide range of management and executive positions
THE IMPACT OF CONSTRUCTION INDUSTRY ON THE CONTENT OF HEAVY METALS IN THE AIR ENVIRONMENT OF KRASNOYARSK CITY
Proceedings of the XXV ISUF International Conference “Urban Form and Social Context: from Traditions to Newest Demands” (Krasnoyarsk, July 5–9, 2018)The construction industry has a significant role in the environmental situation of the city of Krasnoyarsk providing the population with residential, industrial and road construction facilities. A necessary component of construction activity is the enterprises for the production of building materials using a wide range of chemical compounds that annually enter the atmosphere, water bodies, groundwater, soil in the form of industrial emissions, affecting the environmental situation. The construction industry is also impossible to imagine without the use of vehicles, the operation of which is impossible without fuel that absorbs oxygen and emits exhaust gases containing heavy metals in their composition. From the environment dangerous substances enter the human body through the skin, inhaled air, food and eventually cause its functional changes. Exceeding the maximum permissible concentrations heavy metals can have a toxic effect on the human body, so it is necessary to measure their concentration in the air of Krasnoyarsk city regularly. The most common heavy metals entering the atmosphere as a result of industrial emissions include lead, mercury, cadmium, zinc. Lead has a toxic effect, it accumulates in kidneys, liver and other vital organs, gradually leading to disruption of the entire body functioning. Mercury has a toxic effect on the human body, animals and natural components; it is widely used in various industries and a part of a number of pesticides. Cadmium is a chemical element with toxic properties exceeding the properties of lead. It easily passes from soil to plants. Zinc is widely used in the production of paint products, medicine and printing. In case of excessive intake by the body it has a carcinogenic effect
Data Of Daily Blood Pressure Monitoring In Patients With Rheumatoid Arthritis
The aim of present work is to study the frequency of hypertension and the peculiarity of 24-hour blood pressure monitoring in patients with rheumatoid arthritis. We studied 584 patients with rheumatoid arthritis. Daily blood pressure monitoring was carried out in 46 patients with arthritis and 18 patients with essential hypertension. Frequency of hypertension was higher in patients with arthritis then in general population. Elevation of systolic blood pressure, heart rate and arterial blood pressure adequate decrease at night were developed to associate with advance of the disease
Feature of the individual style of Vasily Vasilyevich Rozanov
The present article analyzes the individual style of the famous Russian philosopher, writer, prose writer, and journalist, Vasily Vasilyevich Rozanov. It is proved that the writer's idiostyle is unique in Russian literature of the late 19th and early 20th centuries. The formation of an individual style took place in three stages. At the first stage, the philosophical treatise "On Understanding" was created, in which the categories of knowledge, wisdom, etc. were subjected to philosophical analysis. At the second stage, Rozanov's individual style, the critic, was formed. In this period, the individual style is characterized by inconsistency. At the third stage, Rozanov's individual style is formed, a prose writer, the key characteristics of whose style were unsystematic, contradictory and antinomic
About professional-communicative competence development among students-foreigners at practical lessons in Russian as a foreign (using the example of the lesson "Tasks and functions of Public Relations")
The development of professional and communicative competence is the most important university task. That is why the training of foreign students in a university should be focused on practical knowledge of the Russian language. This article provides the fragment "Tasks and functions of public relations" of the textbook "Training of professional activity in Russian for foreign students studying Public Relations" (by L.V. Adonina, S.V. Lazarev, S.V. Smirnova, O.S. Fisenko)" [12]
