The Ring Goes to Different Cultures: A Call for Cross Cultural Studies of Religious Horror Films

Within the field of religion and media, the study of horror films has always been treated as a minor topic, and cross-cultural comparative studies of such films are even rarer. Furthermore, such comparative projects that involve East Asian contexts, despite their influence on the genre of horror, are yet more difficult to find. By attempting a brief American & East Asian comparative analysis of the Ring series as an example and also proposing an empirical comparative audience research, I call for more cross cultural studies of religious horror films

Enhancement on Radon Adsorption Property of GAC using Nano-size Carbon Colloids

Granular activated carbon (GAC) is well-known as an efficient adsorbent against a number of gaseous pollutants. Radon is one of those pollutants, and radon has been classified as the second leading cause of lung cancer in USA. This study was to enhance the radon removal efficiency with applying nano-technology. Nano-size carbon colloids (NCC) was produced through electrolysis which is simple and cheap. NCC was used for impregnation with activated carbon. Surface areas of both NCC-treated and non-treated activated carbon did not show a significant difference. However, the results of radon removal efficiency show that impregnated carbon with NCC could capture about 1.3 ~ 2 times of more radon gas compared to non-treated activated carbon. It is assumed that nano-size carbon colloids might have filled up meso-pores, and meso-pores turned into micro-pores eventually. Because meso-pores initially accounted for large portion of whole pores, more radon could be captured to NCC-impregnated activated carbon. Keywords: Radon, Nano-Size Carbon Collid, Activated Carbo
