direct contact membrane distillation (dcmd) which emerges as an alternative separation technology can effectively perform a colloidal separation process under thermal driven force. dcmd is capable of extracting pure water from aqueous solutions containing non-volatile nanoparticles through the hydrophobic microporous membrane when a vapour pressure difference was established across the membrane...

The cliassical conditioning explanation of the McCollough effect was extended by investigating blocking and allied phenomena predicted by the Rescorla-Wagner (1972) equations. The subjects were first exposed to colored gratings or moving spirals and then were tested after induction with a compound of both types of stimuli. The effects appeared to be additive, and the stronger stimuli overshadow...
