Unstable even-parity eigenmodes of the regular static SU(2) Yang-Mills-dilaton solutions

In this paper we obtain unstable even-parity eigenmodes to the static regular spherically symmetric solutions of the SU(2) Yang-Mills-dilaton coupled system of equations in 3+1 Minkowski space-time. The corresponding matrix Sturm-Liouville problem is solved numerically by means of the continuous analogue of Newton's method. The method, being the powerful tool for solving both boundary-value and Sturm-Liouville problems, is described in details.Comment: 22 pages, 5 figure

The Enrichment of Stale Tailings of Bom-gorhon Tungsten Ore Deposits

The results of mineralogical studies of technogenic tungsten raw material (stale tailings of Bom-Gorhon deposit) are represented. Its particle size distribution as well as tungsten and accompanying element distribution among the fractions were determined. The necessity of grinding the heaps down to 0.2-0.25 mm in size was established. It allows increasing the recovery rate of two or more times in comparison with the traditional pattern of tailing processing

LASER DOPPLER FLOWMETRY IN ASSESSMENT OF SPECIFICS OF SKIN MICROHEMOCIRCULATION IN HYPERTENSIVE PATIENTS AND IN ITS COMORBIDITY WITH 2 TYPE DIABETES MELLITUS

Aim. To reveal the specifics of microcirculation (MC) in patients with arterial hypertension (AH) and AH with diabetes comorbidity (DM) in groups with low and high micro vessel tone.Material and methods. Studying of the skin MC via the method of laser Doppler flowmetry (LDF) underwent 110 patients with AH, 64 patients with 2 type DM and 55 almost healthy persons. All patients were separated to 2 groups: 1 — with low levels of MC tone, and 2 — with high levels of MC tone.Results. Circa the same percentage spread of MC types in studied groups independently from BP level makes it to suggest that there are general physiological principles of circulation variants forming, directed to maintain hemodynamic homeostasis. Also, in the 2nd group of AH patients and especially in AH+DM there was more significant MC constriction, intensification of arteriolar-venular shunting and decrease of tissue hemoperfusion.Conclusion. The data obtained makes it possible to select among the patients with hypertension disease and its comorbidity with DM 2 type with same grade of AH, the higher risk group with probability of more prominent negative influence on target organs

Апикальная гипертрофическая кардиомиопатия: современные представления о распространенности, клинической картине, диагностике и лечении (обзор литературы)

This review presents the last literature data, concerning prevalence, clinical profile, diagnostic and treatment of apical hypertrophic cardiomyopathy (HCM), as less known among «classical» variants of HCM. It is also discussed the rare form of apical HCM — mid-ventricular HCM with apical aneurism formation. Представлен обзор данных литературы, посвященных распространенности, особенностям клинического течения, диагностике и лечению апикальной гипертрофической кардиомиопатии (ГКМП) как наименее изученному варианту ГКМП. Особое внимание уделяется редкой форме апикальной ГКМП — среднежелудочковой гипертрофической кардиомиопатии, осложненной развитием верхушечной аневризмы

Construction of a Narrativeabout Socialist Realism in English-Language Art Criticism Discourse (based on Texts of Matthew Bown)

Based on the texts of the British expert Matthew Bown, the article deals with the issue of constructing a narrative about the Soviet fine arts. The aim of the study is to analyze the patterns of narrative formation and identify its significant elements. The frame CREATING NEW ART serves as the cognitive basis of the narrative. This frame is characterized by variability and has two main configurations, which can be represented as two scenarios. These scenarios differ in the composition of the actors and the content of the tasks they solve. The actors of the first scenario, actualized in the narrative within the framework of the “friend or foe” opposition, are the ideologists of socialist realism, party leaders and representatives of the creative elite. Their tasks include the formation of the ideology and content of the new art. The actors of the second scenario, updated within the framework of the opposition “self / other”, are Soviet artists. Their task is to develop a language of art that meets ideological requirements and at the same time realizes their creative potential. The article substantiates M. Baun’s willingness to see in socialist realism not only an ideological trend, but also a significant artistic direction. This approach contributes to the disclosure of the value component of socialist realism painting and the transmission of the historical cultural memory of this phenomenon to the world community

The Regularities of Sorption of Noble Metal Ions on Modified Polysilsesquioxanes From Hydrochloric Acid Solutions

Изучена статическая сорбция золота (III), палладия (II) и платины (IV) из солянокислых растворов на полисилсесквиоксанах, модифицированных 3-аминопропильными, 2-аминоэтил-3-аминопропильными и дитиооксамидными функциональными группами. Все три сорбента селективно извлекают ионы благородных металлов по сравнению с сопутствующими ионами s- и d-элементов. Определены условия для количественной сорбции ионов благородных металлов в динамическом режиме на дитиооксамидированном полисилсесквиоксане, а также условия частичного разделения золота (III), палладия (II) и платины (IV). Подобраны составы элюентов для отделения золота (III) от ионов платиноидов на стадии десорбции.The static sorption of gold (III), palladium (II), and platinum (IV) from hydrochloric acid solutions on polysilsesquioxanes modified with 3-aminopropyl, 2-aminoethyl-3-aminopropyl, and dithiooxamide functional groups has been studied. All three sorbents selectively extract noble metal ions compared to the accompanying s- and d-element ions. The conditions for the quantitative sorption of noble metal ions in the dynamic mode on dithiooxamidated polysilsesquioxane, as well as the conditions for the partial separation of gold (III), palladium (II), and platinum (IV), are determined. The compositions of eluents for separating gold (III) from platinoid ions at the desorption stage have been selected
