The concept of appropriate technology has been addressed for electricity production in remote areas of developing countries through the solar ORC technology. The selection of working fluids plays an important role in ORC system. R245fa and R134a are recommended for power generation. In addition, R245fa works well for the heat source temperature of the range 100-120°C whereas R134a below 100°C. Vacuum type solar collector is used for obtaining the hot water which can produce the temperature of 120°C. The commercial scroll expander that adopt magnetic coupling has been used in the...

This edited collection investigates the mobilities, resettlement practices, and identities of North Korean defectors who have relocated to the United Kingdom, the United States, Japan, and South Korea. The contributors to this volume examine the complex nature of defection from North Korea, highlighting the ways in which defectors renegotiate their identities in order to adapt and settle in new societies as well as the implications these differing narratives have on future policy decisions.
