    Поступила в редакцию: 01.06.2021. Принята к печати: 12.10.2021.Submitted: 01.06.2021. Accepted: 12.10.2021.В статье, основанной на материалах экспертных и атрибуционных исследований, проводимых автором на протяжении разных лет, рассматриваются историко-архивные документы, свидетельства и факты, использованные в ходе проведения экспертизы и атрибуций произведений станкового и театрально-декорационного искусства Николая Константиновича Рериха (1874–1947), а также выявляется роль и значение для экспертизы документов из фондов отделов рукописей Государственного Русского музея, Государственной Третьяковской галереи, Российского государственного архива литературы и искусства, Центрального государственного архива кинофотофонодокументов Санкт-Петербурга и других учреждений, что имеет значение для уточнения и изучения художественного наследия мастера. Цель статьи состоит в рассмотрении отдельных примеров проведения экспертизы и атрибуций произведений Н. К. Рериха с помощью разного рода историко-культурных и бытовых документов, фактов и свидетельств, получивших отражение в опубликованных и неопубликованных искусствоведческих текстах, эпистолярных и мемуарных источниках, в надписях на оборотах картин и на полях типографских оттисков выставочных каталогов и произведений искусства Рериха, т. е. всего того, что содержит важную для эксперта информацию, входящую в понятие «историко-архивные аспекты». В статье приведены примеры искусствоведческих, культурологических и технико-технологических методов, применяемых при проведении экспертизы и атрибуций художественных произведений, и их результат, получивший отражение в «заключениях эксперта», атрибуциях, в выверенном и уточненном описании произведений и истории их бытования, что имеет важное значение для понимания искусства художника, дальнейшего анализа его творчества и, как следствие, появления новых научных и просветительских изданий.Based on the materials of expert and attribution studies carried out by the author over the years, this article examines the historical and archival documents, evidence and facts used in the course of the examination and attribution of works of easel, theatrical and decorative art of Nicholas Roerich (1874–1947). Also, the author examines the role which documents from the funds of the departments of manuscripts of the State Russian Museum, the State Tretyakov Gallery, the Russian State Archives of Literature and Art, the Central State Archive of Film and Photographic Documents of St Petersburg, and other institutions play in the examination process, which is important for clarifying and studying the artistic heritage of the master. The purpose of the article is to consider individual examples of the examination and attribution of N. K. Roerich’s works with the help of various kinds of historical, cultural, and everyday documents, facts, and evidence reflected in unpublished art history texts, epistolary and memoir sources, in inscriptions on the reverse of paintings and on the margins of typographic prints of exhibition catalogues and works of art by Roerich, i.e. everything that contains important information for an expert included in the concept of “historical and archival aspects”. The article provides examples of art history, culturological and technical and technological methods used in the examination and attribution of works of art, and their result, which is reflected in the “expert conclusions”, attributions, verified and refined description of works and the history of their existence, which is important for understanding the artist’s work, further analysis of his work and, as a result, the emergence of new scholarly and educational publications

    X-ray films were exposed inside the ionization calorimeter under 74g/sq cm of carbon and 5 cm of lead. The X-ray film chamber area is 35 sq. m. Moving X-ray films were used, 50% of the events, which succeeded to determine incidence time, were identified with corresponding extensive air showers (EAS). For such events the size spectrum of associated EAS was derived. Two methods of energy measurement using X-ray films and ionization calorimeter were compared. The energy transfer from selected hadron to electromagnetic component is illustrated. It is found that in cascades with high energy release into electromagnetic components the hadron component is practically absent

    Postdocs in Russia: Peculiarities of Employment and Incentives

    The article presents the results of the author’s research aimed at identifying the peculiarities of employment of postdocs, a relatively new labor category for the Russian academic labor market. Due to several difficulties associated with forming a sample of postdocs (difficulty in identifying key persons responsible for the development of postdoctoral programs; direct, but not always justified, refusals to provide data, difficulties in identifying potential respondents due to their occupation of various scientific positions in Russian universities), the “snowball” method was used. As a result, the empirical basis of the study was formed based on the results of an online survey of 44 postdocs. As part of the study, tasks related to compiling a socio-economic portrait of a postdoc based on economic, socio-demographic characteristics and indicators of research efficiency, identifying the characteristics of the employment and placement experience of postdocs, objective factors and individual motives for making decisions in the field of choosing postdoctoral programs were solved, as well as diagnostics of tools and channels for young researchers to search for vacancies. The authors distinguish between types of academic mobility (educational and labor) and consider postdoctoral studies as a promising form of external labor academic mobility aimed at attracting and retaining high-potential young researchers planning a long-term career in the academic labor market.Shifting the emphasis from the inbreeding model of university development (internal labor mobility) to the model of external labor academic mobility of young specialists allows those universities that can effectively manage the flow of academic human capital to receive additional socio-economic preferences and return on investment. There are very few similar empirical studies that analyze the features of the development of postdoctoral institutions in Russia and abroad and are based on quantitative and qualitative data from surveys of direct participants in external labor academic mobility – postdocs, which determines the scientific novelty and practical value of the proposed results

    Studies on the formation of groundwater levels have been carried out on open and closed drainage systems in the natural and climatic conditions of the Novgorod region for more than 30 years at 2 pilot production sites. On the first site there are 4 structures of closed drainage: shallow with a depth of 70 cm; medium-deep drainage (drainage depth 110 cm) with various options for filling the drainage trench-wood chips and sand-gravel mixture; two-tier drainage (drainage depth 110 and 60 cm). On the second site there are four open drainage structures: channels; hollows – without hydro-reclamation structures; with drainage along the bottom-tubular and strip-free. The average long-term data on groundwater regimes on experimental structures were obtained and conclusions were drawn that the average seasonal groundwater level formed by closed drainage systems is 18 cm lower compared to open drainage systems; the most favorable groundwater regime is formed by drainage systems of two-tier drainage. The dependences of groundwater levels formed during the most intense periods of operation of drainage systems (May – 1st decade of June) on the amount of precipitation for previous periods are analyzed. It was revealed that the closeness of the relationship between groundwater levels and the amount of precipitation in the open drainage variants is less close (r2 = 0.01-0.30) compared with the closed drainage variants (r2 = 0.02-0.54). The closest relationship on closed drainage systems is observed between the groundwater level of the third decade of May and precipitation for May: during this period, with an increase in precipitation by 1 mm, groundwater rises by 0.3 cm – in the variant with chip filling and by 0.6 cm – in the variants of shallow and two-tier drainage

    This article contains results of experimental research of polytetrafluoroethylene (PTFE) deformation and creep under linear and plane stresses. During the tests predetermined values of real stresses considering current deformation were constant. The equation of mechanical states considering instant elastic, viscoelastic, instant plastic and viscoplastic components of total deformation was obtained. The equation is used for the description of PTFE deformations (F-4, F-4D, F-4D0) under stationary and non-stationary cyclic loads in flat stress condition with an application of material constant volume condition, condition of similarity of deviators of stresses and deformations and with the input of parameters which are functions of the form of stress deviators. The results of PTFE creep investigation under real stresses reaching ultimate values are relevant and unique

    Background. Yellow rust (Puccinia striiformis West.) is a harmful disease of cereal crops. Significant yellow rust in cidence has systematically been registered on VIR’s experimental fields in Derbent (Dagestan) and Pushkin (North western Russia). Resistance assessment and subsequent selection of resistance sources for breeding require proper monitoring of the virulence in the pathogen’s local populations. The purpose of this work was to characterize the virulence of P. striiformis on VIR’s experimental fields in Derbent and Pushkin, and use molecular markers to find out whether the studied P. striiformis isolates belong to any of the most dangerous invasive groups PstS1 and PstS2.Materials and methods. In Derbent, leaves with uredinio pustules were collected from bread and durum wheat accessions; in Pushkin, from bread wheat and triticale plants. The pathogen’s virulence was analyzed in the laboratory using the world and European sets of differential cultivars, and isogenic Avocet Yr lines. In 2020, the resistance of differential sets was tested in the field in Derbent under a high natural infection pressure. SCAR markers were used to identify the invasive PstS1 and PstS2 isolates. Results and conclusion. A total of 18 phenotypes (races) of striiformis were identified (4 in Derbent, and 14 in Pushkin). The Yr5, Yr10, Yr15, Yr17, Yr24 and Yr26 genes manifested high effectiveness in both locations. In the field, immune responses were observed in the Avocet lines with the Yr5, Yr7, Yr8, Yr10, Yr15, Yr24 and YrAR genes, and in the differential cvs. ‘Vilmorin 23’, ‘Moro’, ‘Reichersberg 42’, ‘Heines Peko’, ‘Nord Desprez’, ‘Compare’, ‘Carstens V’, ‘Spaldings Prolific’ and ‘Heines VII’. Moderate resistance was recorded for the line Jupateco 73R (damage up to 5%), and cvs. ‘Heines Kolben’ and ‘Strubes Dickkopf’ (5–10%). Using molecular markers, 2 isolates from the invasive group PstS2 were identified in the Pushkin collection of P. striiformis
