The Life and Vegetating
No full textFor several years, A.V. Suvorov has been doing mailing lists for like-minded colleagues and friends. Each of the letters is a scientific and journalistic text on philosophical, psychological, pedagogical, and life topics. A.V. Suvorov signed his letters "Hedgehog" - that's how he called himself, meaning not only prickly, but also the desire to isolate himself for a while, shrink, withdraw into himself from the world, so that he could then turn to him with something important. We bring to your attention his latest essay, or rather, the last revision of the text that he wrote almost a quarter of a century ago. The author reflects on how to overcome universal, collective and individual, personal nonsense as a way of existence. In his opinion, didactics is intended to provide a means of understanding existence.</p

No full textThe article concerns ways of teaching argumentation to foreign students learning Russian as a foreign language. The author characterizes extracts of A.V. Vampilov's “The Elder Son” where different verbal persuasive means showing menthality, specifiс way of thinking and world perception of the Russians are presented
Large-eddy simulation of turbulent channel flow using the explicit algebraic subgrid-scale model
No full textLarge-eddy simulation (LES) of turbulent channel flow are performed with a new subgrid-scale (SGS) stress model. The simulations show that with this model we can well predict turbulent wall flows at coarse resolutions and moderately high Reynolds numbers. The commonly used dynamic Smagorinsky model fails at coarser resolutions
Explicit algebraic and differential Reynolds stress model application to homogeneously sheared and compressed turbulence
No full textAn explicit algebraic and differential Reynolds stress models (EARSM and DRSM) are used to investigate the influence of homogeneous shear and compression on the behaviour of turbulence in the limit of rapid distortion theory (RDT). EARSM is shown to give realizable results and to preserve RDT regime, unlike the eddy-viscosity model (EVM). The DRSM version of our model is in reasonable agreement with RDT theory
Generalissimo A.V. Suvorov: General’s Persona in Memory Politics of Early 20th Century Russian Empire
No full textThis article addresses the utilization of heroic imagery from the past within the memory politics of the early 20th century Russian Empire. The author provides a detailed analysis of the commemoration of A.V. Suvorov’s feats during the reign of Nicholas II. It is demonstrated that the centenary of Suvorov’s death catalyzed a resurgence of interest in this heroic figure. Based on archival documents and periodical press, the study shows that efforts to immortalize the general continued after the centennial anniversary. The research establishes that Victorian themes occupied a central position in the symbolic politics of autocratic power throughout this period. The author concludes that the state actively employed the heroic image of A.V. Suvorov to legitimize the existing order and unify the empire’s populace. It is emphasized that, in the early 20th century, key instruments for shaping the memory landscape included the construction of a pantheon of national heroes, the establishment of museums, the organization of celebratory ceremonies, and the execution of educational initiatives, alongside monumental commemoration. The author asserts that narratives from military history were instrumental in creating cultural infrastructure both within and beyond the state’s borders. This article is of particular interest to researchers exploring issues related to historical memory and memory politics in the early 20th century

This article summarizes the data on carotenoids and their role in retinal antioxidant protection. The relevance of lutein and zeaxanthin complexes and criteria for their choice are discussed. Data on the relationship between low carotenoid levels in the fovea and age-related macular degeneration (AMD) are available. There are several lutein and zeaxanthin complexes which formulations were developed according to the AREDS2. Clinical trials demonstrate that lutein and zeaxanthin complexes improve both retinal functional activity and morphological parameters and are effective to prevent AMD development and progression. They are recommended for unbalanced diet, gastrointestinal disorders, psychoemotional stresses (e.g., drivers or professional athletes), intensive ultraviolet (e.g., welders, lighters or mountain tourists), myopia, accommodation cramp, inflammatory and degenerative ocular disorders. Optimal dosing is 1 tablet per day for at least 3 months twice a year.
Key words: lutein, zeaxanthin, carotenoids, antioxidants, age-related macular degeneration.

Sense of “Axial time” in A.V. Semushkin and M.K. Mamardashvili’s creativity
No full textIn the article considers the concept of “axial time”, developed by K. Jaspers. Through a prism of A.V. Semushkin and M.K. Mamardashvili’s creativity opens its essence determined as “spiritual revolution”. Defined its specific features, as consequence of this “break to transcendent”: universalism, an opportunity of the communication, birth of philosophy, world religions and sciences; history, person and morals. Degradation the modern culture, expressing in growth of conflicts and wars, communicate the author with deviation from revelations of “axial time” that threatens mankind with self-destruction
The influenza A virus NS genome segment displays lineage-specific patterns in predicted RNA secondary structure
No full textBackground: Influenza A virus (IAV) is a segmented negative-sense RNA virus that causes seasonal epidemics and periodic pandemics in humans. Two regions (nucleotide positions 82-148 and 497-564) in the positive-sense RNA of the NS segment fold into a multi-branch loop or hairpin structures. Results: We studied 25,384 NS segment positive-sense RNA unique sequences of human and non-human IAVs in order to predict secondary RNA structures of the 82-148 and 497-564 regions using RNAfold software, and determined their host- and lineage-specific distributions. Hairpins prevailed in avian and avian-origin human IAVs, including H1N1pdm1918 and H5N1. In human and swine IAV hairpins distribution varied between evolutionary lineages. Conclusions: These results suggest a possible functional role for these RNA secondary structures and the need for experimental evaluation of these structures in the influenza life cycle. © 2016 The Author(s)
A.V. CHAYANOV ON THE WAY TO THE THEORY OF NON-CAPITALIST ECONOMY
No full textAlexander V. Chayanov (1888-1937) is a famous Russian economist, theorist of the organization of economy, a brilliant representative of the generation of the “golden age” of the economic science in Russia. One of the key elements of his scientific legacy is the theory of non-capitalist forms of economy, and one of its aspects - international agrarian studies of the features of the organization of agriculture in different countries. The organizational-production school developed a theory of labor economy and came close to the general theory of non-capitalist forms of economy; however, its studies were inter-rupted by the repressions of the 1920s. The article considers the international studies of A.V. Chayanov to clarify and develop some findings of the today’s scholars (I.A. Kuznetsov, A.M. Nikulin, T.A. Savinova). The author proposes a new interpretation of the organizational-production school as having a dualistic character. The works of Alexander N. Chelintsev (1874-1962), Nicholay P. Makarov (1886-1980) and other colleagues of A.V. Chayanov from the organizational-production school focused on both theoretical issues such as the fundamental laws of functioning and development of agriculture, and practical issues of scientific management of an individual farm and agriculture in general. The author considers the orga-nizational-production school as dualistic: it studies both theory and management of peasant economy at micro- and macro-levels proceeding from the analysis of the individual farm structure to the issues of the optimal production location and optimal management of ‘a mass of peasant farms’. The system approach to the organization of economy, cooperation, zoning and economic policy developed by the organizational-production school is still relevant for the contemporary use
