Based on a sociological survey conducted among residents living in mining areas of the Tyva Republic (Tuva), this article examines the impact of industrial development on the region’s socio-economic advancement, particularly focusing on the environmental situation and the well-being of the population. The study identifies the sectors significantly affected by the economic exploitation of the territories and establishes the foundation for sustainable growth in these mining areas. By employing cluster analysis, we categorize the development districts into three equilibrium states: indifferent, unsustainable, and sustainable. The research distinguishes the Tandinsky and Dzun-Khemchiksky districts as they remain unaffected by mining enterprises. In contrast, the Todzhinsky District demonstrates environmental degradation due to active mining operations. The Kyzylsky District is currently approaching a sustainable equilibrium state, with mixed changes observed across all three dimensions: economic, social and ecological. While negative assessments exist, positive ones prevail overall. The article also reveals divergence in collective assessments. Although clusters of values align closely on certain issues such as improving electricity supply, road quality, and increasing air pollution, opinions diverge on other aspects. The most notable divergence occurs in the assessment of wages and the local population’s purchasing power.

In today’s context, there is an urgent need to find new mechanisms for fostering domestic tourism. To formulate effective strategies for developing the tourism potential of specific territories, it is necessary to gather data on the tourist preferences and tastes of both visitors and residents. This study aims to create an applied tool for tourism design by utilizing a netnographic analysis of social networks. Through it, we identify the most appealing locations in Volgograd. The findings of this research can be used to optimize the allocation of tourism resources among these territories. The proposed consumer content analysis method, devised by the author, enables precise identification of each tourist cluster and optimization of its boundaries, thereby providing more comprehensive insights into tourist distribution in space and preferences.

This article examines the evolution of cost-benefit analysis methods in line with advancements in science and technology. It proposes a comprehensive set of interconnected models that combine an expanded financial and economic model as their basis, an optimization multiregional input-output model, along with detailed financial and economic models for individual subprojects and econometric models for some public effects. These models are utilized to evaluate the efficiency of large-scale investment projects. The study then focuses on four scenarios of technological changes and presents the calculation formulas for each key stage. Using these methods, the research assesses, for the first time, the performance indicators of “Akademgorodok 2.0, " a large-scale real project with a 2013-2030 timeline and an investment of 299 billion rubles. When considering constant 2013 prices, a cost-benefit analysis reveals a net discounted income of800 billion rubles at a 7% discount rate, or 1964 billion rubles without discounting. These figures demonstrate that the project’s financial, economic, and budgetary efficiency indicators align with evaluations of similar mega science installations in Europe.

In the new geopolitical and economic landscape, the transformation of cross-border relations and the strengthening of integration processes with Central Asian countries, particularly in the so-called “eastern vector, " hold significant importance for the development of Russia and the Eurasian Economic Union. Within this context, Siberia’s role in fostering such interactions, with a specific focus on collaboration among regional scientific, educational, and innovation ecosystems, is increasingly vital. This article examines the potential of cross-border cooperation in science, technology, the training of highly skilled professionals, and various approaches to advancing such cooperation. Specifically, it focuses on the dynamic Republic of Kazakhstan and Novosibirsk, which has emerged as the primary scientific and innovative hub for Eurasian cross-border interactions in Asian Russia. By exploring the establishment of a branch of Novosibirsk State University and an Akademgorodok in the city of Konaev, Kazakhstan, the article illustrates the steps involved in Russian-Kazakh scientific, technological, and educational cooperation, as well as the expected outcomes of these collaborative efforts.

This article assesses the role of Transbaikalia in the Russian economic space and explores its development potential in the new geopolitical landscape. Transbaikalia, identified as a key geostrategic region, serves as a vital link between the Far East and the rest of Russia. Moreover, it acts as a gateway to the primary land corridor extending deep into the Asian mainland. The study explores the trade and financial interactions of Transbaikalia with China and Mongolia, particularly within the China-Mongolia-Russia economic corridor, as well as its own potential for development through increased business activities with neighboring countries. The analysis draws upon customs data, banking information, and business statistics. It highlights a lower level of economic activity within local communities in Transbaikalia when compared to partners along the economic corridor. Furthermore, it emphasizes the peripheral position of Transbaikalia in federal strategies for macroregional development and the prevailing pattern of interaction in the northern direction, i.e., from China to Russia. This raises the issue of prioritizing the development of this region at the federal level, which is crucial for ensuring economic security amid the intensifying Asian direction of the country’s global engagement.

The study’s relevance is substantiated by the strategic goal and practical significance of economic cooperation and integration, as well as the advancement of cultural and political collaboration between neighboring states. The research involves analyzing socioeconomic data of cross-border territories and zoning the Kazakhstan-Russia border area. This comprehensive study can serve as a foundation for detecting border security risks and examining the stability of the Kazakhstan-Russia border. The findings reveal the existence of four socioeconomic regions within the Kazakhstan-Russia cross-border area: Western, Central, Northern, and Eastern, each with its specifics. The Western and Northern regions are identified as having predominantly developed territories, whereas the Central and Eastern ones exhibit lower levels of development and economic prosperity. Interestingly, a consistent pattern emerged, indicating significant developmental asymmetry between adjacent border areas in the more developed territories, whereas such disparities were minimal in the less developed regions. Overall, the research findings demonstrate notable differences in socioeconomic parameters across the Kazakhstan-Russia cross-border region.

This article investigates how structural, institutional, and spatial factors influence business performance in Novosibirsk Oblast. The study utilizes data from the SPARK-Interfax database for the years 2019-2020, focusing on enterprises in the region. The empirical analysis employed regression models and an extended production function approach to examine how various factors influence enterprise revenue and profit. In addition to assets and labor remuneration, the study assessed the impact of factors such as industry affiliation, firm age, ownership form, and distance to the regional capital. The findings reveal that private businesses and young firms demonstrate higher productivity and profitability, underscoring the importance of supporting entrepreneurship and new ventures in the region. Furthermore, industrial and service businesses outperform the agricultural sector, suggesting targeted assistance for agriculture may be warranted. The analysis highlights the significant contribution of agglomeration effects to firm performance in Novosibirsk Oblast, comparable to national averages.

This paper presents the results of an experimental study of flames propagating with a sign-variable speed, in methane-air and coal-methane-air mixtures in a vertically located closed pipe at coal dust concentrations of 0.10 ÷ 0.42 kg/m³. The results of the study can be useful for developing combustion models and assessing dynamic and thermal effects during combustion of methane-air suspended coal in coal mines.

Experimental studies of combustion stability to a local excess of a component in a dispersed mixture of titanium and carbon powder are presented. The influence of the spreading of a melt of a fusible or liquid reaction product on the stability of the combustion transition through a solid and perforated carbon powder barrier is considered. The direction of melt movement with respect to the direction of front propagation has been studied. It is shown that the stability of the combustion transition through the barrier is determined by the thermal interaction between the combustion wave and the barrier and is not directly related to the convective heat transfer by the melt.
