A development of the low power engine for work on a krypton
... propulsion appears to be an undisputed alternative for the chemical thrusters. Also, even the best solutions provided by electric propulsion technology still require optimization despite its more than of half a century history. Currently xenon is the propellant of choice for ion and Hall effect thrusters, however xenon is very expensive, that’s why different cheaper propellants appears as an alternative fuel for advanced electric propulsion thrusters

Military and political cooperation between Germany and Lithuania in the late 2010s to early 2020s
Since the mid-2010s, Germany has significantly adjusted its approaches to the use of the Bundeswehr, pivoting its strategic focus from regions distant from the Euro-Atlantic community to those within or near it. This has underscored the pressing need to address issues related to securing steadfast allies in Eastern Europe and enhancing cooperation with them. This article aims to explore the current evolution of German-Lithuanian relations in both political and military domains. The approach of...
Three Russian Baltic regions in the context of confrontation between Russia and the West
This study examines the features, limitations and development prospects of three Russian territories bordering the Baltic Sea — St. Petersburg, and the Leningrad, and Kaliningrad region — amid the sharply heightened confrontation between Russia and the West, which has affected the Baltic region. The time frame spanning from 2014 to 2023 was chosen for the study. This period encompasses the sanctions imposed by Western countries and their associations, primarily the EU, in response to the return...
Geography of the mobile internet in the border and interior regions of Russia
... availability of 4G (and in the future, 5G) internet connectivity facilitates more extensive utilization of digital technologies by individuals and businesses, resulting in a substantial increase in the volume of digital data and information flows, thus propelling economic and social activities forward. The surge in the number of mobile subscriber devices is not solely attributable to new users among the region’s residents but also correlates with the diversification of their technical devices that ...

Creation of the effective cathode jack for the micro-SPD
... challenges which are faced in development and manufacturing of the cathode-compensator dedicated for micro-SPTs, and possible ways of how to overcome them. As compared to standard models, such a cathode shall be smaller in dimensions, shall have a lover propellant flow rate, as well as lover heater power and power consumption when self-operated; and it shall be able to operate in the current range of 0.3…1A or lower.
