The postindustrial economy did not take the place of previous types of economy. More than that, by definition, it hasn't become “post”-industrial in point of fact: relations with regard to the production of tangible goods define the imperative of industrialism, yet with a modern science and technology stage of development. The present-day production becomes increasingly automated, leading to the absence of demand for psychophysiological properties of man and labor in general. At the same time, highly qualified personnel who are able to control complex information management systems come to the fore. New types of energy and manmade materials appear; socioeconomic human living environment becomes more complicated. These processes are an objective phenomenon. However, the technological revolution is manifested differently in the “central” and “peripheral” countries. In the Russian Federation, formation of the innovational takes place in the conditions of integration of the resource model and opposition of the institutes that fund it. The crisis stimulates the conceptual search and does not deny the scientifically based classics.

After the collapse of the USSR, Eurasian integration projects, proposed by Russia, Kazakhstan and Turkey, began to develop in the post-Soviet space. Hence, there is growing interest in Eurasianism as an ideology. In this context, the study of the use of the Eurasianism's ideas in practice becomes relevant. The argument of this article is that Russia, Turkey, and Kazakstan have their own interpretations of Eurasianism's ideas to develop the ideological basis of their own integration projects. The purpose of the article is to answer the question: How is the Eurasianism used in integration projects of Russia, Turkey and Kazakstan?

The concept of Eurasianism has been viewed in terms of constructivism. On the basis of the principles of social constructivism, and in particular the works of constructivist ideologue Alexander Wendt, a comparative analysis was made. The ideas of Eurasianism in the integration processes of Russia, Kazakhstan and Turkey has been carried out based on the criteria such as the role of common ideas, identity, consciousness, memory and culture. The examples of mentioned countries were compared, to consider the development of the ideas of Eurasianism in practice.

The ideas of Eurasianism have a significant impact on the integration processes of the post-Soviet space. Eurasianism advocates for important factors such as respect for cultural and civilizational differences between different nations, their equality in the overall union and common development opportunities. Such factors are undoubtedly important for the success of integration projects. The reflection of many individual thoughts of classical Eurasians and Neo-Eurasians can be seen in the statements of various ministers and leaders of Russia, Kazakhstan and Turkey. The initiatives of these countries in creating integration projects also show the influence of the Eurasian concept.

In the 1990s, the study of Eurasianism gained new significance in academic circles. Articles and periodicals devoted to this concept were published. However, all parallels between variations in concepts of Eurasianism have been conducted on a theoretical level. The importance of this article lies in the fact that conceptual differences are compared in practice. Researchers had not previously considered the study of the relevance and productivity of Eurasianism in practice by comparing examples and experiences from different countries. The novelty of this article lies in its attempt to solve this problem.

The use of explicit finite difference schemes for low Stefan number problems with moving interface was largely abandoned because they require small time intervals (large CPU time) to obtain accurate non‐oscillatory solutions. This paper uses these type of schemes for better estimations of the dynamics of the solid—liquid interface. The scheme in which time and radial intervals are constant, uses a local, continuous, time‐dependent radial coordinate to define the instantaneous location of the interface. Taylor series expansions which result in a polynomial fit are used for forward and backward interpolation of temperatures of nodal points in the vicinity of the interface. A distinction is made between the left and right position of the interface relative to the closest nodal point. The algorithm handles accurately and effectively the non‐linearities near the interface thus producing accurate stable solutions with relatively low CPU time. The scheme which obviously may be applied to large Stefan number problems, is also suitable for time dependent boundary conditions as well as temperature dependent physical properties. The results obtained by the scheme were in excellent agreement with ones derived from an approximate analytical solution which is applicable in the low Stefan number range.

The purpose of this paper is to consider a procedure of water-water energetic reactor (WWER) reactor pressure vessel (RPV) lifetime prediction at the stages of design and lifetime extension using the standard irradiation embrittlement parameters as defined in regulatory documents. A comparison is made of the brittle fracture resistance (BFR) values evaluated using two criteria: shift in the critical brittleness temperature ΔT_c or shift in the brittle-to-ductile transition temperature ΔT_p and without shifts (T_c and T_p).

The radiation resistance was determined using the following three approaches: calculation based on standard values ΔT_c and T_c0 or ΔT_p and T_p0 (a level of excessive conservatism); calculation based on standard value ΔT_c and actual value T_c0 or actual values ΔT_p and T_p0 (the level of realistic conservatism); or calculation based on actual values of T_c and T_c0 or T_p and T_p0 (the level of actual conservatism). The BFR was evaluated based on the results of testing the specimens subjected to irradiation in research reactors as well as surveillance specimens subjected to irradiation immediately under operating conditions.

The excessive conservatism in determining the actual lifetime of nuclear reactor vessel materials can be eliminated by using the immediate values of critical brittleness temperature and ductile-to-brittle transition temperature.

Obtained results can be applied to extend WWER vessel operating time at the stages of designing and operation due to substantiated decrease in conservatism. And it will allow carrying out a statistical substantiated assessment of the resistance to brittle fracture of the RPV steels.

Managing complex construction projects is a challenging task because it involves multiple factors and decision-making processes. A systematic evaluation of these complex factors is imperative for achieving project success. As most of these factors are qualitative or intangible in nature, decision makers often rely on subjective judgements when comparing and evaluating them. The hybrid techniques that integrate fuzzy set theory and the analytic hierarchy process (AHP) are able to deal with such problems. This chapter discusses various hybrid techniques of the fuzzy AHP and presents an application of these techniques to the evaluation of transportation project complexity, which is essential for prioritising resource allocation and assessing project performance. Project complexity can be quantified and visualised effectively with the application of the fuzzy AHP. This chapter enhances the understanding of construction project complexity and fuzzy hybrid computing in construction engineering and management. Future research should address the calibration of fuzzy membership functions in pairwise comparisons for each individual decision maker and develop computational tools for solving optimisation problems in the constrained fuzzy AHP. In the area of construction project complexity, future research should investigate how scarce resources are allocated to better manage complex projects and how appropriate resource allocation improves their performance.

Under current conditions, strong sustainable socio-economic development of major metropolitan areas in separate regions and separate countries comparable to them in size is possible with the optimal management of a set of anti-epidemic measures to combat the COVID-19 pandemic. This chapter constructs the first numerical model of the quasi-periodic dynamics of the COVID-19 pandemic. It was created based on the innovative model of the Kondratiev waves developed by the authors in their previous works. The authors found a close approximation between the model and the actual data for the four waves of development of the COVID-19 pandemic in Moscow. It was also noted that this model applies to small countries close in population to Moscow when comparing the correlation and autocorrelation curves. The data calculated by the models indicate the possibility of the practical application of the developed model for metropolitan areas and small countries comparable to them in size and population. Additionally, the model showed the accuracy of the results for such large countries as Russia and the United States.

The main purpose of the chapter is to analyze social research data on divorce in the USSR and Russia. The main method is literature review of statistic data on divorce since WWII and the results of representative opinion polls and local surveys, including author’s data.

The central conclusion is that methodological level, theoretical basis and continuity in empirical divorce research has been lacking in the last 25 years in the USSR and Russia (it concerns research techniques never piloted before; lack of clear definition and operationalization of variables when studying different aspects of divorce, etc.).

The chapter offers original research framework of divorce analysis – socially maladaptive family. It is includes external contexts of family functioning (changing legal norms concerning divorce and public opinion on it) and three aspects of “reproduction of human being” in family (material means for living; quantitative reproduction of the population, including birthrate; and qualitative reproduction of the population, including personal characteristics of family members and relationships between them).

Acquaintance with the content of the chapter will be useful for researchers of the family (especially who are interested the problems of divorce and quality of marriage) as foreign as Russian.
