Unveiling the evolutionary patterns of Ecistic space in the Saratov region during the latter half of the imperial era (1800–1917)
Abstract
This study delves into the profound transformation of demographic and Ecistic space within the contemporary Saratov region during the latter half of the imperial era (1800–1917). Spatial and temporal trends, as well as the driving forces behind their development, have been meticulously examined. The findings reveal a fascinating process of Ecistic space metamorphosis within the region. This intertwines with the wave-like dynamics of numerous socio-technical innovations (including the emancipation of serfs and the establishment of free land trade, state peasant reforms, the advent of the industrial revolution, and the sweeping Great Reforms). It is evident that the colonization phase of territorial exploration and the establishment of a fundamental hierarchical framework (governorate > district > volost > city > village) within the Ecistic space of the region have reached their culmination.

Intraannual and interannual changes in clouds in Ufa
Abstract
The study of cloud cover and its characteristics (quantity and forms) is of practical interest, especially for large cities. Cloud cover, having a dual effect (albedo and greenhouse), is an important factor in the formation of the thermal regime in the conditions of global climate change. This article presents the results of the analysis of daily, annual and long-term changes in the cloud cover regime in the city of Ufa(Republic of Bashkortostan). Urgent data from long-term observations of clouds (1966–2020) were used for the analysis. The main patterns of the daily course of clouds in the months of the cold and warm period of the year are revealed. The long-term dynamics of cloud cover has shown that its number has a significant upward trend.

Changes in transport use in Russian urban and rural settlements of different population sizes over the period 2014–2022
Abstract
The aim of the study is to examine the dynamics of transport use and transport service in urban and rural settlements of Russia with different population sizes in 2014–2022. The hypothesis of the study is that the dynamics of transport use and transport service in rural settlements repeats the dynamics of transport use and transport service in urban settlements with a certain time delay. With the general growth of transport use, there is a continuing growth in the use of personal passenger cars (including motorbikes) with a simultaneous decrease in the use of public transport. Gradually decreasing differences between urban and rural settlements have been revealed for most of the comparable indicators. In many cases the studied indicators for rural settlements change along the same trajectory (with the same dynamics) as the indicators for urban settlements, with a lag of several years. Transport use and transport services for men and women also tend to approach the same values in all types of settlements. A general pattern is observed: as the population density of a settlement increases, the problems of transport service of the population decrease.

Pilot innovative territorial clusters: Spatial differentiation, patterns of development and efficiency
Abstract
The article is devoted to the study of an important component of innovative infrastructure – pilot innovative territorial clusters. The main stages of their formation were considered, spatial patterns of development, structure and economic efficiency were identified and analyzed. The purpose of the study is to analyze the spatial regularities of pilot innovative territorial clusters functioning to justify the promising directions of the state cluster policy contributing to the effective use of the financial resources of the federal budget by determining priority investment directions and establishing on this basis the recipients of state support in the cluster with the greatest potential in the context of limited financial resources. This is promising primarily for justifying the stimulation of new high-tech industries and enterprises. The study was carried out on the basis of materials from official federal and regional statistics, information and analytical reports of the Association of Clusters, Technoparks and SEZs of Russia, official ratings of regions innovative development, legislative acts of the federal and regional levels. Patterns of functioning and trends in the development of innovative territorial clusters have been identified. The main purpose of the emerging innovative territorial clusters is to saturate the huge domestic market with high-tech goods, services and technologies in order to achieve the country’s technological independence. Promising directions for improving the cluster policy of Russia are formulated.

Principles and methods for studying the structure of metageosystems for designing a pilgrimage-tourist cluster
Abstract
Introduction. The article characterizes the spatio-temporal structure of metageosystems of the pilgrimage-tourist cluster “Sanaksar – Temnikov”, located in the center of the Russian Plain, in the zone of interaction of forest-steppe and forest geosystems. Materials and methods. The structuring of information within the framework of the study is based on the simultaneous use of a natural sequence of involving interrelated principles: genetic, historical, systemic, territorial-structural. The object of study was investigated from the perspective of a geosystem approach, the structure and components of metageosystems were analyzed as spatial formations of different levels of organization, naturally functioning. Research results and discussion. A detailed description of the geosystem model of the tourist cluster “Sanaksar – Temnikov” is given. It has been proven that the sustainable development of metageosystems should be based on multifactor information support, in which the most important condition for the effective economic development of landscapes is realized through the formation of a regional spatial data infrastructure. Based on the analysis of the archaeological map of the Republic of Mordovia, patterns of development of cultural landscapes are identified. The characteristics of the processes and features of the economic development of geosystems and the formation of cultural heritage have been formed. Conclusion. The organization of a pilgrimage and tourism cluster places high demands on information support. Solving the problem of forecasting and monitoring the development of metageosystems for making management decisions is possible using methods and algorithms for processing and analyzing spatial data, designing and implementing project-oriented geoportal systems for distributing spatial data.

Insoluble remains of Lower Permian sylvinite rocks in the western and north-western framing of the Caspian depression
Abstract
The paper presents the results of a study of the insoluble residue of sylvinites and sylvin-halite rocks of the Lower Permian halogen formation, common within the Perelyubsky areas (Western and Eastern), promising for industrial development (Saratov Region) and the Gremyachinsky potash deposit (Volgograd Region). A technique for studying the insoluble residue of sylvinites is presented. The types of insoluble residue are distinguished according to the form of occurrence in sylvinites and its mineral composition is characterized. The conditions for the formation of sylvine-bearing rocks are refined, taking into account the data obtained on the composition of the insoluble residue.

On the role of salty coals in kaolinite transformation into paragonite-type hydromica within the Donbass tonsteins
Abstract
The character of kaolinite hydromicatization within the Donetsk Basin tonsteins in the course of metamorphism depends on the types of enclosing coals: either normal or salty ones. Alongside with terrigenous minerals within the coal-bearing masses and the fossil sea waters, indicator authigenous minerals from salty coals – halite and glauberite – should be specified as the sources of sodium and potassium for kaolinite hydromicatization. The conditions, most favorable for formation of the most stable phase of paragonite-type hydromica in kaolinite interlayers, arise within paralic formations over the areas of alkaline caustobioliths formation in the course of metamorphism. In the case when halite and glauberite from salty coals make the principal source of sodium, brammalite generation begins in matatonsteins during anthracite formation. The process goes on until feldspars and micas begin active supply of potassium into chloride Cl-Ca-Na brine. From this moment on, brammalite in clay interlayers is being rapidly replaced with illite. Eventually, association of paragonite and muscovite-type hydromicas arises within the clay interlayers. If the principal source of the alkaline elements responsible for kaolinite hydromicatization consists of terrigenous minerals from normal (nonsaline) coal-bearing masses (potassium feldspars, micas, plagioclases), exclusively illite develops within metatonsteins.

Irrigation system in the Late Cretaceous Hexactinellids (Porifera, Hexactinellida)
Abstract
Within the skeletal structure of the medium- and the thick-walled Hexactinellids, the active filtration surface area was increased at expense of the elements of the irrigation system. The ostia and the transversal canal structures, the densities of their occurrences correlate with the values of the wall thickness, the skeleton habitus, the level of modular organization; they are in many ways determined by the parameters of the sponge habitats.
