No full textStrength and Stability Analysis of Load-bearing Structures of Evolution Tower with Allowance for Actual Positions of Reinforced Concrete Structural Members
No full textAbstractThe distinctive paper is devoted to strength and stability analysis of loadbearing structures of Evolution Tower (high-rise 54-storey building) with allowance for actual positions of reinforced concrete structural members (columns and walls). Finite element method (FEM) is used for structural analysis. The authors present formulations of problems, governing equations, information about basic three-dimensional finite element models (so-called “design” (ideal) model, the first “actual” model (taking into account the deviations of positions of columns from the project) and the second “actual” model (taking into account the deviations of positions of walls from the project)) of the coupled system “Evolution Tower – foundation” within ANSYS Mechanical software and their verification, numerical approach to structural analysis and corresponding solvers. Finite element models include mainly 4-node structural shell elements (suitable for analyzing foundation slabs, floor slabs and load-bearing walls) and three dimensional 2-node beam elements (suitable for analyzing beams and columns), special spring-damper elements and multipoint constraint elements. Detailed finite element mesh on the bottom foundation slab is agreed with the location of piles. The advanced model of Prof. Yu.K. Zaretsky is used for approximation of soil behavior. Construction sequence and various types of nonlinearities are taken into account. The results of modal analysis, static and dynamic analysis with various load combinations (gravity load, façade load, dead (constant) loads, temporary loads, wind load, snow load, crown load etc.) are considered, the results of the regulatory assessment of the strength of structures (obtained with the use of corresponding software in accordance with design codes of the Russian Federation) are under consideration as well. The corresponding displacements, stresses, natural vibration frequencies can be used for research and development of the correct monitoring method of the foundation and load-bearing structures of a high-rise building
Monetary and fiscal policy measures during the COVID-19 economic crisis in Russia
No full textThe author examines how monetary and fiscal policy influences the shocks facilities in the Russian economy caused by the coronavirus pandemic. The article aims to provide an economic assessment of the monetary measures by the Central Bank and the Government of the Russian Federation to overcome the consequences of the COVID-19 crisis. The author exploited the methods of content analysis, benchmarking, and logical analysis. The study covers the period of March - July 2020 and relies on the analysis of data from international organizations, analytical centers, mass media, official data sources of the Government of Russia and the Central Bank of the Russian Federation. The literature review and the analysis of the Mundell-Fleming model contribute to the better understanding of monetary policy of countries in its connection with fiscal policy. The author analyzed the monetary and fiscal measures against the COVID-19 crisis in Russia and other countries. The study provides the assessment of the COVID-19 shocks and the remedial actions. The conclusion is that when most economic activity is prohibited, lower interest rates cannot stimulate it in the short term. More visible are the efforts to maintain liquidity in the economy, as financial institutions often have troubles. During the analysis, the work focuses on the theoretical foundations of monetary policy and its connection with fiscal policy, as well as provides a number of stylized facts of its implementation in Russia during the coronavirus pandemic. This can be useful for further empirical research and practical recommendations in the field of monetary and fiscal policy in the Russian Federation. © Zaytsev Yu.K, 202

Lithuanian folk songs in V. Ivanov’s translation
No full textThe study is devoted to the publication of Vyacheslav Ivanov’s Russian translation for Lithuanian folk songs, made for unpublished collection of Lithuanian literature (“Sbornik litovskoj literatury,” Petrograd, [1915–1917]; ed. by Iu. Baltrushaitis, M. Gorky). Around the same time, Baltrushaitis was the editor-compiler and translator of the collection of Lithuanian folklore at the publishing house of M. Sabashnikov. This project was also not implemented. Ivanov’s work on Lithuanian translations is chronologically close to his participation in other collections of national literatures. In an extensive introductory article, the author reconsctucts the history of the creation of translations from Lithuanian, using the correspondence of V. Ivanov, Y. Baltrushaitis, M. Sabashnikov. The research shows that Ivanov’s work on translations for the Lithuanian collection stretched from the beginning of 1916 to the summer months, when the poet’s family lived in a village near Sochi. The preamble also contains information about the first publication of an incomplete collection of these translations, made in 1973 by Yu. Tumyalis using unauthorized typescript from the Manuscript Department of the Institute of Lithuanian Literature and Folklore (Vilnius). In this publication, the texts of Ivanov’s translations are given by autographs from the Manuscript Department of the Institute of Russian Literature (Pushkinskiy Dom) of RAS and the Roman Archive of Vyach. Ivanov. The textual comments describe the currently available sources of Ivanov’s translations, such as correspondence of Iu. Baltrushaitis, epistolary materials of others, Ivanov’s preparatory materials, manuscripts, translations from the archival storages of St. Petersburg, Moscow, Rome, Vilnius. Кeywords: V.I.

Ophthalmic risk factors for primary open angle glaucoma
No full text
Primary open angle glaucoma (POAG) is a chronic progressive optic neuropathy, characterized by morphological changes in the optic nerve head and retinal nerve fiber layer. This review analyzes the development of the risk factors for POAG over several decades. The role of systemic diseases as a risk factor has been proven, and ophthalmological factors contributing to the progression of glaucoma are currently being actively studied. The most studied of these is ocular hypertension. A number of studies have shown an effect of both the average increase in the level of intraocular pressure (IOP) and its peak rises during the day on the progression of glaucomatous optic neuropathy (GON). Pseudoexfoliation syndrome and pigment dispersion syndrome, which are characterized by changes in the structures of the eye that increase the sensitivity of the nervous tissue to IOP level differences, can lead to increased IOP levels. An increase in the axial length of the eye associated with myopia is also considered to be a risk factor for the POAG development. In myopia, especially when high severity, there is a stretching of the fibrous tunic of the eye and changes in the structures of the fundus. These changes may be mistakenly diagnosed as glaucomatous, and may also contribute to the GON development. This review provides a summary of current data on the ophthalmic risk factors for the POAG development, which will improve the diagnosis of this disease.
Keywords: primary open angle glaucoma, risk factor, ocular hypertension, pseudoexfoliation syndrome, pigment dispersion syndrome, myopia, myopic refraction.

Conflicting patterns of thought in the Russian debate on transition: 2003-2007
No full textThis article is a continuation of two essays by the same author on Soviet/Russian economic debates between 1987 and 2002 published in Europe-Asia Studies in 2006 and 2007, so now the series of articles covers 20 years of Soviet/Russian discussions on economic reforms. Should Russia strive to become a 'Western' country marked by democracy and a market economy serving the individual interests of its citizens, or was it more important to become a great power again? Are Western patterns of political and economic life suitable for Russia or is the attempt to import foreign institutional structures doomed for failure, making it necessary for Russia to find her own way? This type of question, going far beyond the realm of economics, was and still is at the heart of the debate among Russian economists, which shall be discussed here, on the basis of a qualitative content analysis of the most important economic journals and selected monographs. --
From the Allerød to the mid-Holocene: Palynological evidence from the south basin of the Caspian Sea

A relatively sharp lithological change at 0.86 m depth reflects a shift from detrital silts to carbonates-rich fine silts. From this depth upwards, a Holocene chronology is built based on ten radiocarbon dates on ostracod shells and bulk carbonates. From the vegetation point of view, the Late Pleistocene deserts and steppes were partially replaced in the most sheltered areas by an open woodland with Pinus, Juniperus-Hippophae-Elaeagnus and even Alnus-Quercus-Pterocarya and Fraxinus, related to the Allerød palynozone. This was interrupted by the Younger Dryas palynozone when Artemisia reaches a maximum in a first instance followed by a very dry phase with only a slight return of Pinus and Quercus and the rare presence of Ulmus-Zelkova. From 11.5 to 8.4 cal. ka BP, an open landscape dominated by shrubs such as Ephedra and progressively increasing Quercus appeared. The final spread of diverse evergreen and deciduous trees is delayed and occurs after 8.4 cal. ka BP. It is suggested that this delay is caused by an arid climate in the Early Holocene linked to high insolation and perhaps to a lake effect. The dinocyst assemblages fluctuate between slightly brackish (Pyxidinopsis psilata and Spiniferites cruciformis, 7 psu and lower) and more brackish (Impagidinium caspienense, ∼13 psu). In the Lateglacial (Khvalynian highstand), the assemblages remained dominated by relative low salinity taxa. A late and brief increase of salinity occurred prior to 11.2 cal. ka BP associated with the Mangyshlak lowstand. It is suggested that it was caused by a brief drop in meltwater flow from both the north and the southeast (Uzboy) and a likely evaporation increase. This lowstand occurs quasi at the same time as the end of a longer lowstand in the Black Sea. The freshest waters are then inferred as having occurred between 8.4 and ≤4.4 cal. ka BP, linked to a connection with the Amu Darya and the melting glaciers on the Pamir Mountains. The Caspian Sea is a sensitive environment, easily perturbed by global climatic changes, such as the Allerød and Holocene warming, and the Lateglacial and Younger Dryas cooling, as well as by regional changes in its hydrography, such as shifts in the Eurasian meltwater and the Volga and Amu Darya inflows.Centre National de la Recherche Scientifique, Franc
