Wintering Areas of the White-Tailed Eagle in Southern Kazakhstan
No full textThe White-Tailed Eagle (Haliaeetus albicilla) is a rare species with declining numbers listed in the Red Book of Kazakhstan. In the Turkestan Region it is present during migration and wintering periods with the earliest sighting on September 10 (2018), and the latest on March 23 (2021) (Koksarai Reservoir, Gubin, 2020). Since 2003, wintering birds have been regularly observed on water bodies. Initially, counts were conducted in December–February, but starting from 2006 – in mid-January. The participants included S.N. Erokhov from 2003 to 2005, O.V. Belyalov in 2003 and 2004, F.F. Karpov in 2004 and 2006, A.V. Kovalenko from 2005 to 2014 (Kovalenko, 2015), S.A. Kravchenko in 2005 and 2006, B.M. Gubin from 2016 to 2018 (Gubin, 2020), and the author together with A.Zh. Abayev and M.A. Yaganin in 2014, 2020–2022
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

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
Lutein and zeaxanthin complex: ophthalmologists’ choice

LLC “Three-Z-Moscow”, Moscow, Russian Federation
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.

The strategy was developed by the Working Group consisting of I.V. Karyakin (Chairman of the Working Group), A.V. Kovalenko, A.N. Barashkova, I.E. Smelansky, E.G. Nikolenko. Preparing the Strategy the recommendations and proposals provided by O.A. Goroshko, R.A. Medzidov, M.V. Pestov, V.N. Pimenov, A.V. Saltykov were taken into account.
The Draft Strategy was approved by the participants of the international scientific-practical conference “The Eagles of the Palearctic: study and conservation” (Yelabuga, Republic of Tatarstan, Russia, September 20–22, 2013) and of the Ministry of Natural Resources and Ecology of the Russian Federation.
Strategy of the Steppe Eagle conservation in the Russian Federation is published in Russian and English.
Action plans for the conservation of the steppe eagle in the three pilot regions of the UNDP/GEF/MNR Steppe Project (Republic of Kalmykia, Orenburg region and the Trans-Baikal (Zabaikalskiy) Kray) have been published as an annex to the Strategy

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
