#### Spatial differentiation of rural territories in the Kaliningrad region: implications for socio-economic policies

The article analyses the challenges associated with the development of rural areas in the Kaliningrad region. The author analyses trends in the development of agriculture, population **dynamics**, and settlement patterns, while also exploring their interconnectedness and external impacts. The research draws upon comparative-geographical, economic-statistical, and cartographic analyses utilizing official statistical data. The study reveals ...

#### An Attempt to the economic and geographical analysis of the differentiation of the Russian Federation subjects on of the level and **dynamics** of the retail trade development

The level and **dynamics** of development of retail trade in the context of the subjects of the Russian Federation are highly differentiated. Differentiation is influenced both by the income level of the population and by other factors, since there is no functional dependence ...

#### On strengthening the territorial differentiation of the rural population and the agrarian sector of the economy in the Russian Federation

Rural settlement in Russia and its **dynamics** are subject to the general laws of spatial development of the economy and demography, the most important of which is polarization. At the same time, regional settlement systems differ greately due to both physical and economic geographical ...

#### Coastal location as a development factor of the cities in the Baltic region

Population **dynamics** is one of the key categories of socio-economic development of territories. Cities, as the main carriers of innovative potential, need constant influx of human resources. The purpose of this article is to identify the nature of the influence of ...

#### Age-related **dynamics** of competence formation in social work

The article analyses the formation of social competences in the field of education and social work in Kaliningrad. The author identifies performance indicators according to age and the **dynamics** of competence formation in representatives of three age groups. The three age groups analyzed demonstrate significant differences in both the overall competence as such and its individual components. The results of the research can be used in ...

#### Modeling the formation of ion shadows behind a positively charged microsatellite in an oxygen plasma by the molecular **dynamics** method

Results of modeling the formation of ion shadows in a thermal ionospheric plasma consisting of oxygen ions and electrons behind a charged microsatellite are presented. The molecular **dynamics** method was used for modeling. It is shown that in a time of the order of 610-5 s an ionic shadow with a low ion concentration is practically formed.

#### A modeling the interaction of a oxygen plasma with a positively charged microsatellite with the molecular **dynamics** modeling method

The results of modeling the interaction of a single-ion thermal ionospheric plasma consisting of oxygen ions and electrons with a charged microsatellite are presented. The molecular **dynamics** modeling method was used. It is shown that behind the satellite there is a so-called ionic shadow with a low ionic concentration.

#### 2D modeling of ion shadow behind a charged satellite by the method of molecular **dynamics**

It was considered a two-dimensional model of the interaction of a charged micro satellite and thermal plasma. The method of molecular **dynamics** used as a modeling method. Ion concentration distributions near SC were calculated for 10 and 102 protons in cm2 and the two values of relative satellite velocity and plasma were considered — 8 and 20 km s-1, respectively. It is shown that ...

#### Mathematical model of transportation of relativistic electronic beams. Analogy to the equations of gas **dynamics**

Analytical comparison of hyperbolic system consists of four equations for moments of the distribution function of relativistic electron beam (REB), the modeling transportation processes in the gas environment and the equations of gas **dynamics** of ideal polytropic gas was carried out. The found analogy between these models allowed to specify mathematical statement of a problem for REB and to facilitate a choice of edge conditions of the task.

#### Landscape **dynamics** in the Kaliningrad region over a historical period

This article offers a comparative characteristic, based on the data of spore and pollen and radiocarbon analyses, of landscapes **dynamics** in the Subatlantic in three landscapes typical of the Kaliningrad region: the Vištytis upland, the Neman River delta lowland, and the Pregel lake-glacial plain. E. V. Maksimov's 1850-year rhythm model was used for data interpretation.
