Long wave propagation, shoaling and run-up in nearshore areas

This paper discusses the possibility to study propagation, shoaling and run-up of these waves over a slope in a 300-meter long large wave flume (GWK), Hannover. For this purpose long bell-shaped solitary waves (elongated solitons) of different amplitude and the same period of 30 s are generated. Experimental data of long wave propagation in the flume are compared with numerical simulations performed within the fully nonlinear potential flow theory and KdV equations. Shoaling and run-up of waves on different mild slopes is studied hypothetically using nonlinear shallow water theory. Conclusions about the feasibility of using large scale experimental facility (GWK) to study tsunami wave propagation and run-up are made.Alexander von Humboldt foundationRFBR/14-02-00983RFBR/14-05-0009

Mutations designed to modify the NS gene mRNA secondary structure affect influenza A pathogenicity in vivo

The influenza A virus genome consists of eight segments of negative-sense RNA that encode up to 18 proteins. During the process of viral replication, positive-sense (+)RNA (cRNA) or messenger RNA (mRNA) is synthesized. Today, there is only a partial understanding of the function of several secondary structures within vRNA and cRNA promoters, and splice sites in the M and NS genes. The most precise secondary structure of (+)RNA has been determined for the NS segment of influenza A virus.  The influenza A virus NS gene features two regions with a conserved mRNA secondary structure located near splice sites. Here, we compared 4 variants of the A/Puerto Rico/8/1934 strain featuring different combinations of secondary structures at the NS segment (+)RNA regions 82-148 and 497-564. We found that RNA structures did not affect viral replication in cell culture. However, one of the viruses demonstrated lower NS1 and NEP expression levels during early stage cell infection as well as reduced pathogenicity in mice compared to other variants. In particular, this virus is characterized by an RNA hairpin in the 82-148 region and a stable hairpin in the 497-564 region.The influenza A virus genome consists of eight segments of negative-sense RNA that encode up to 18 proteins.

THE PROBLEM OF THE IMAGE OF PUBLIC SERVANTS IN RUSSIA

The formation of a favorable image is an integral part of the professional growth of public servants. Modern society imposes special demands on the image of public service employees. In this regard, their image should consist of a set of certain characteristics that emphasize the effectiveness and professionalism of their activities. To effectively create the image of public servants, it is necessary to pay attention to their personal characteristics, as well as to properly organize a PR company. A positive image is one of the main tools for the formation of communication between the state and society with the placement of significant priorities. The formation and development of a positive image is a multi-level, complex and responsible process, which requires hard work so that a public servant can inspire confidence and meet the expectations of citizens. Despite the fact that today the image is one of the most important tools of influence and management, its essence should be exclusively in the pursuit of good goals. It should be aimed at identifying and subsequently solving the main problems of citizens, as well as an active dialogue with society

TECHNOLOGIES OF IMAGE FORMATION ON THE EXAMPLE OF CIVIL SERVANTS OF DIFFERENT LEVELS AND TYPES

The process of forming the image of a civil servant should be carried out in two directions: influencing the external environment – public opinion, using the media, and the internal environment – the formation of a personal image. The rationale for the need to form a stable positive image of a civil servant has been presented in the article. The most popular image formation technologies, their concepts, characteristics and goals, as well as their application methods have been considered. The use of image formation technologies has been studied on the example of Russian civil servants at the Federal and regional levels, as well as civil service and military service. The features of the direction in forming the image of each of these types have been analysed

Foundation of psychological support in the emotional experience of professional identity crisis by teachers

The background of the researched problem is determined by the psychological and pedagogical science’s and practice’s need to supplement the ideas about teachers’ professional development and about the course of their getting through the emotional experience due to difficulties of this process; as a result, it is necessary to study psychological foundations of building of psychological support programs in the process of school teachers’ getting through a professional crisis under conditions of permanent changes in the educational system. The main approach to studying this problem is the interview and phenomenological method that allows to identify and justify psychological basis of building of teacher support programs. The theoretical analysis allows to identify the nature of the support process, its goals and objectives, and to justify the methodological basis of the support program realization. The empiric results demonstrated that the process of teachers getting through the professional identity crisis goes hand in hand with the value-semantic transformation of a person and with “launching” of reflexive processes which, in turn, justifies resorting to them as to the psychological basis of building of teacher support programs. The research results expand the understanding of the nature of professional identity crisis phenomenon, the process of coming through it and supplement the data of the basis of building of teacher support programs. © 2018 by the authors

Specifics of defense and coping behavior among teachers experiencing a professional identity crisis

The issues addressed in the article are of particular relevance due to the necessity to provide research background for creating the system of psychological and pedagogical support for the professional development of teachers in the conditions of permanent changes in the system of education. The aim of the article is to describe specific interrelations between the reflection and the parameters of the teacher's axiological sphere (in particular, life-purpose orientations). The following research methods were used: theoretical analysis of psycholog-ical and educational literature, phenomenological method, questionnaires, and methods of mathematical and statistical data processing (descriptive statistics, comparative analysis (the Mann-Whitney U test). The results of the theoretical and empirical research provide ade-quate grounds for the conclusion that there is a definite interrelation between the parameters of reflection and the parameters of life-purpose orientations. It is proved that in the conditions of a professional identity crisis the teachers experience a significant reduction in the levels of life-purpose orientations, which in turn leads to intensification of reflection processes. At the same time, the obtained results suggest that the teachers can successfully overcome their professional crisis in case of formation of the cognitive component of the biographical reflection, aimed at the analysis of actions and means of understanding and organizing their life events. Implications of the research results. The research results expand our understanding of the essence and emotional experience of the professional identity crisis. They can be used in the designing the process of psychological support for the activities and professional development of teachers. © 2018 Authors

Statistical analysis of the spatial distribution of impurities in the snow cover in the vicinity of copper mine in the Middle Ural of Russia

Statistical analysis of the monitoring data of industrial enterprises influence zones is an important part of the researches related to natural environment changes. In present study, a cluster analysis of the elemental composition of the snow cover in the vicinity of a copper mine was carried out. The data were obtained as a result of the chemical analysis of the snow samples collected during annual environmental monitoring in the region of Rezh town (the Middle Ural of Russia), where Safyanovsky Copper Mine and Rezhevsky Nickel Plant are located. The elements identified by chemical analysis were grouped according to the strength of the correlation bond. The cluster analysis of these groups made it possible to identify and separate the influence zones of the Plant, Mine and other industrial objects located in the area. The obtained results became the basis for adjusting the snow cover monitoring scheme. © 2018 Author(s).The research is supported by the project of the Ural Branch of Russian Academy of Sciences No. 18-5-2345-56

Aromaticity in a Surface Deposited Cluster: Pd4_4 on TiO2_2 (110)

We report the presence of \sigma-aromaticity in a surface deposited cluster, Pd$_4$ on TiO$_2$ (110). In the gas phase, Pd$_4$ adopts a tetrahedral structure. However, surface binding promotes a flat, \sigma-aromatic cluster. This is the first time aromaticity is found in surface deposited clusters. Systems of this type emerge as a promising class of catalyst, and so realization of aromaticity in them may help to rationalize their reactivity and catalytic properties, as a function of cluster size and composition.Comment: 4 pages, 3 figure
