The dehydrochlorination of 1 , 1 , I-trichloro-2,2-bis(p-chlorophenyl)ethane to its nontoxic, ethylenic analogue, DDE,* by extracts of DDT-resistant houseflies (1Musca domestica) was first demonstrated by Sternburg et al. (I). It was shown that this system was GSH-dependent and that no DDT dehydrochlorinase could be detected in DDT-susceptible flies by the means then available. The titer of DDT...

The clutch temperature rise characteristics in successive shifting conditions are crucial to its thermal stability and safety. In the present paper, a comprehensive numerical model is proposed investigate change of separator discs during with consideration convection heat transfer disengaged friction pair gaps, which validated by repeated experiments on SAE#2 test bench. Since second disc near ...
