In-situ, low dose rate, total ionising dose test of the cooling performance of a thermoelectric module
This work presents and discusses the design and fully automated total ionising dose test of a thermoelectric cooling module. The goal was to develop a reliable test method which can be used to measure potential total ionising dose induced degradation of the cooling performance and demonstrate this method in a long term, low dose rate experiment. Details of the tested hardware and fully automated test system are published in this work, including preliminary test results and lessons learned.
A total ionising dose, in-situ test campaign of DS18B20 temperature sensors
Comprehensive tests are being performed to identify if the Dallas DS18B20 smart digital temperature sensor is i) a potential solution for temperature monitoring during in-situ gamma irradiation tests and ii) a suitable candidate for commercial low cost space applications. This work presents and discusses an applied test methodology for total ionising dose (TID) irradiation using a cobalt-60 gamma source. Preliminary test results are also published in this paper.
Socioeconomic and Security Implications of Chinese Migration in the Russian Far East
Several dimensions of migration from China into bordering areas of the Russian Far East (primarily Primorskiy Kray) are subjected to critical assessment: scale of migration economic impacts (for migrants and host regions) attitudes of the host-region population and regional security implications. The analysis suggests that the Russian Far East generally has limited economic attraction for Chinese migrants despite the importance of migration for cross-border relations and trade. The study is based on data from Russian statistical border and migration services; extensive interviews and on-site observations; review of regional newspapers; and a large (N= 1010) opinion survey of the local population.
