High-frequency wave phenomena present a great deal of interest as one of the possible candidates to contribute to the energy input required to heat the corona as a part of the AC heating theory. However, the resolution of imaging instruments up until the Solar Orbiter have made it impossible to resolve the necessary time and spatial scales. The present paper reports on high-frequency transverse motions in a small loop located in a quiet Sun region of the corona.The oscillations were observed with the HRIEUV telescope (17.4 nm) of the EUI instrument onboard the Solar Orbiter. We detect two transverse oscillations in short loops with lengths of 4.5 Mm and 11 Mm. The shorter loop displays an oscillation with a 14 s period and the longer a 30 s period. Despite the high resolution, no definitive identification as propagating or standing waves is possible. The velocity amplitudes are found to be equal to 72 km/s and 125 km/s, respectively, for the shorter and longer loop. Based on that, we also estimated the values of the energy flux contained in the loops -the energy flux of the 14 s oscillation is 1.9 kW • m −2 and of the 30 s oscillation it is 6.5 kW • m −2 . While these oscillations have been observed in the Quiet Sun, their energy fluxes are of the same order as the energy input required to heat the active solar corona. Numerical simulations were performed in order to reproduce the observed oscillations. The correspondence of the numerical results to the observations provide support to the energy content estimates for the observations. Such high energy densities have not yet been observed in decayless coronal waves, and this is promising for coronal heating models based on wave damping.

The SSI rates are significantly higher than previously reported. Although this finding may be attributable to inadequate antibiotic prophylaxis, local infection control and surgical practices may also be contributors. Use of antibiotic prophylaxis should be encouraged and the effect of local practices further investigated. Active SSI surveillance should be expanded to other parts of the Russian Federation.

Introduction. In modern Russian society, the requirements for the general level of the school educational process have resulted not only from the demands related to the content of educational programmes, but also from sufficiently high requirements for a teacher personality. A modern teacher has to build up a holistic and harmonious image, ranging from stylish and modern appearance to a high level of professionalism. The image of a teacher directly or indirectly influences the effectiveness of the mutual action of the members of education. Therefore, the reflection of various aspects, which form the image of the teacher in order to correct it in accordance with the existing school realities, is a relevant direction of psychological research.The aim of the present research is to identify the most significant and preferred characteristics of the image of a modern teacher in the perceptions of high school students.Methodology and research methods. The methodological framework of the research is based on psychosemiotic approaches in social psychology: the concept of modern psychosemiotics of communication by E. A. Petrova and theoretical positions of objective and subjective psychosemantics by E. Yu. Artemyeva, V. F. Petrenko and A. G. Shmelev. The selection of psychodiagnostic methods was based on three-factor models of imageological space organisation. The perceptions of high school students about such characteristics of the image as the appearance of the “ideal” and “bad” teacher were studied using a projective technique. The method of free semantic survey, supplemented by the method of “Factor Space of the Teacher Image” by E. A. Petrova, was used to study personal, professional and communicative features. Such method allowed the authors to structure the students’ ideas about the image of the teacher by categories related to personal characteristics: attitude to own profession, attitude to students and educational activities. The images of teachers of different types were created through the psychosemantic technique developed by D. Peabody in A. G. Shmelev’s adaptation. The non-parametric criterion of differences – Mann-Whitney U-test was employed to identify the differences in high school students’ ideas about the image of the modern “ideal” teacher depending on gender.Results and scientific novelty. It was established that the attitude of high school students to the teacher mostly depends on teacher’s professional and personal qualities. School students especially highlighted the following aspects: the high level of mastery over the subject taught; teachers’ ability to interest students in educational material; cooperation with students and objective assessment of their knowledge. Significant positive personality characteristics included the ability to interact constructively and kindly with each student, as well as the high level of activity and positive energy of the teacher. The students think that a teacher’s appearance does not play a determining role. However, the respondents noted that it is important for them that the teacher prefers the business style of clothing and looks modern and neat.Practical significance. The research results can be applied in the practice of school psychological service and in coaching activities in order to inform the teaching staff and interested teachers about the role of image when building effective interactions in the system “teacher-student”.

This article presents the results of multivariate correlations between regional governance system performance indicators and key indicators of socioeconomic territorial development based on modern economic and mathematical tools. The representation of the socioeconomic system of the region as a space of key variables of socioeconomic territorial development and regional authorities' performance indicators allows the use of canonical correlation analysis tools. The analysis is performed on the indicators calculated for the regions of the Russian Federation for the period of 2008-2010. As a result, weak correlation was found between subject-object variables of meso-level economic systems. A visible correlation in two sets is observed between economic territory development and indicators of executive authorities' performance such as the average monthly wage of civil servants of executive authorities of the Russian Federation constituent entities, tax and non-tax share of municipalities budget income in total municipalities budget income and the number of employees in the executive branch of the constituent entities of the Russian Federation. The lack of correlation between performance indicators of regional governance systems and socioeconomic territorial development requires a revision of the existing formal approach to this evaluation.

Pinus sibirica and P. pumila are Asian five-needle pines with vast geographic distributions that are partially overlapping. Natural hybrids with intermediate morphology have been found previ­ously, but there is a lack of evidence of ongoing introgression. The goal of our study was to elucidate the genetic structure of P. sibirica and P. pumila populations growing in the north-east of their sympatry zone (Aldan plateau) using cytoplasmic DNA markers. All studied P. sibirica and P. pumila trees had usual spe­cies-specific growth habits. Using nad1 intron2 of mitochond­rial DNA (mtDNA) and trnV of chloroplast DNA (cpDNA) we found that trees morphologically identified as P. sibirica had pumila-specific mtDNA. Moreover, some of them also had pumila-specific cpDNA. P. pumila trees were typical and had pumila-type cytoplasmic DNA markers. These results suggest that interspecific hybridization took place long ago and lead to introgression and cryptic hybrids with P. sibirica appearance and P. pumila mtDNA

In this paper, the authors propose a comprehensive monitoring system for the quality of life of the population in the Russian regions, including methodological assessment tools and information-analytical system using Data Mining methods, allowing public authorities to justify and adjust programs aimed at its improvement. The comprehensive monitoring system includes: descriptive and comparative analysis of statistical and analytical materials for a certain period of time, characterizing the quality of life of population in the Russian Federation regions; the rationale and implementation of choosing the most important basic components of this assessment; development of a system of indicators to measure the quality of life of population in the Russian regions; the choice of a particular method of synthesis of partial indicators into a single integrated index. The information and analytical system for monitoring the quality of life of the population in the Russian Federation regions is based on a data warehouse containing statistical indicators and an analytical platform that allows to evaluate data using Data Mining processing technologies: multidimensional data presentation; rating analysis; cluster analysis of the quality of life of the population in the Russian regions using the Kohonen learning rule. At the final stage of monitoring, the priority strategic directions for improving the quality of life of the population in the Russian regions are identified.
