The article is devoted to the analysis of various theoretical approaches to the study of labor relations formed in the post-Soviet Russian sociology of labor. The need to study new market labor ...relations that arose in the late 1980s, as well as the discussion in this regard about their subject and priority areas of research, were implemented within the concepts of sociological realism and nominalism in the first 20 post-Soviet years. In the 1990s, systemic and conflict approaches (including Marxist and pluralist paradigms) dominated alongside studies carried out using the "case study" strategy (biographical, ethnographic and monographic methods). Since the beginning of the 2000s, neoinstitutional and cultural (including civilizational) approaches that are close to each other have been formed. The shift of the research focus from the study of stable labor relations in industry to the study of their precarious forms in organizations of the non-industrial sector, which occurred in the mid-2010s, was accompanied by the formation of resource and neo-Marxist approaches, as well as their synthetic forms (interdisciplinary approach called "new working class studies"). These synthetic forms are close to the methodology of sociological constructivism. Based on the results of the analysis, conclusions are drawn about the need to revise existing interpretations of labor relations and develop a new approach, based on the domestic methodology of the sociology of life. This new methodology can make it possible to study the real meanings of labor relations and the world of work for each of the groups of hired workers.

We present the first Thomson scattering (TS) measurements of electron temperature in the lower divertor of the Globus-M2 tokamak. The divertor TS diagnostics is designed for local measurements of the

= 24 cm and covers areas of the inner leg, vicinity of separatrix and private flux region. Along probing chord of 110 mm, 9 spatial points were realized. Advanced filter polychromators were used to analyze Thomson scattering spectra.
The possibility of the application of high-uranium self-irradiation-damaged metamict zircon for U-Pb geochronological studies (ID-TIMS) after preliminary high-temperature annealing and acid treatment ...was demonstrated using zircon from the Li–F granites of the Turga massif (Eastern Transbaikalia). Optimal conditions of high-temperature annealing and acid treatment of zircon with high self-irradiation α-dose can be selected to remove completely a metamict phase and preserve sufficient quantities of the mineral for U-Pb (ID-TIMS) studies.
Thomson scattering of the core edge and divertor plasma regions of a tokamak with reactor technologies is discussed. The rationale and choice of technical solutions are given, the composition of the ...Thomson scattering diagnostic complex is discussed, as well as an estimate of the accuracy of measuring both electron temperature and density. Particular attention is paid to ensuring the functionality of the proposed diagnostics in the reactor mode of the tokamak operation and the results of testing diagnostic equipment in the experiments on Globus-M2 tokamak.
Giant cerebral aneurysms are diagnosed more often in children than in adults. Treatment of giant aneurysms is carried out both by endovascular and microsurgical methods. Literature information on ...combination of microsurgical and endovascular operations of cerebral aneurysms at children is little. A clinical case of the combined treatment of a giant bicameral fusiform partially thrombosed aneurysm of the right vertebral artery at a 12-year-old patient and a literature review on this topic are presented. The patient underwent several complex neurosurgical interventions during two operations: 1) microsurgery including revascularization of the right posterior lower cerebellar artery, thrombectomy and trapping of the larger chamber of fusiform aneurysm of the right vertebral artery, and 2) endovascular, which consists in the installation of redirecting stent from the left vertebral artery to main artery. The uniqueness of the case which we presented lies in the fact that the tactics of stage combined treatment for a complex aneurysm at child was originally planned and successfully implemented. The treatment allowed to ensure a complete shutdown of aneurysm and to exclude postoperative cerebral complications.
The typological analysis of the first-year students' educational strategies in the conditions of experimental learning within individual learning pathways have been considered in the article. Using ...the heuristic potential of the typological approach in relation to the data of a mass questionnaire survey of first-year students at the Tyumen State University, two parts of type-forming features were identified and the corresponding empirical indicators were formed. Using the methods of factorial and cluster analysis, three modal typological groups of first-year students have been discerned, and each of them has its own educational strategy at the university. Conclusions have been drawn about the expediency of building such a typology at the beginning of the student's educational pathway, as this enables to make timely management decisions on the development of desirable and correction of undesirable learning strategies, as well as the possibility of further monitoring measurements.
Surgical treatment of patients with cerebral aneurysms still remains one of the most important issues of cerebrovascular neurosurgery, which is associated with both complexity of treatment and risks ...posed by the disease. The purpose of this publication is to discuss the recommendations and algorithms adopted at the Neurosurgical Institute for choosing surgical treatment of patients with single and multiple intracranial aneurysms based on the clinical course of disease and anatomical morphological classifications of aneurysms. The study was based on a large clinical material: we analyzed treatment outcomes in 1,621 patients (2009-2017); of these, 966 (59.5%) patients were operated on using microsurgical techniques, and 655 (40.4%) patients underwent endovascular surgery. Surgical treatment of patients with cerebral aneurysms has been performed in close cooperation between two vascular (microsurgical and endovasal) departments, using the latest technical innovations.
