Elaborating Religious Guidelines for Technological Development

Abstract
Some philosophers and thinkers have made serious criticisms of modern technology, considering it the cause of major problems. These critiques and problems have motivated some philosophers to think of alternatives for technology. Andrew Feenberg, one of the scholars seeking alternatives for technology, argues that the modern technical system is derived from the values of capitalism and serves a select few. As a diagnosis, Feenberg considers the capitalistic values to be the root of modern technological crises and as a prescription, he recommends a “democratic technological design system”. Feenberg has proposed no criteria for evaluating the values that could be incorporated into the...

Abstract
The mechanism of surfactants in surfactant-in situ chemical oxidation (S-ISCO) coupled process for trichloroethene (TCE) degradation was firstly reported. The performance of TCE solubilization and inhibition of TCE degradation in three nonionic surfactants (TW-80, Brij-35, TX-100) in PS/Fe(II)/citric acid (CA) system was compared and TW-80 was evaluated to be the optimal surfactant in S-ISCO coupled process due to the best TCE solubilizing ability and minimal inhibition for TCE degradation (only 31.8% TCE inhibition in the presence of 1 g L−1 TW-80 surfactant). The inhibition mechanism in TCE degradation was also demonstrated by comparing the strength of ROSs and PS utilization. In the...
