The early work of Fineberg and Greenberg 128) as well as that of Drysdale and Monroe 129) indicate that oral or intramuscular administration of iron enhances the rate of ferritin synthesis in the intestinal mucosa as well as other tissue. Drysdale and Monroe foimd little effect of actinomycin, an inhibitor of RNA synthesis, on iron-induced ferritin synthesis and suggested that the apoferritin was stabilized by being bound to the iron core. Recently Yoshino et al. 130) using higher concentrations of actinomycin were able to inhibit markedly the induced synthesis of ferritin. The mechanism for iron induction of ferritin is certainly not clear at this time.

A novel method for generating semidione radicals has recently been reported by Monroe, Weiner, and Hammond 178) who found that the quantum yield for photoreduction of camphorquinone in 2-propanol was markedly enhanced when benzophenone was added and the solution irradiated at wavelength 3660 A where most of the light was absorbed by benzophenone. Instead of benzpinacol formation, the dione underwent photoreduction. Similar enhancement was not observed with jw-methoxy-acetophenone which does not abstract hydrogen from 2-propanol. The conclusion was that the ketyl radical, formed in the efficient H-abstraction reaction of benzophenone, transferred a hydrogen atom to camphorquinone to generate the semidione radical. It was suggested that this phenomenon be called "chemical sensitization .

The case kpem 1 corresponds to the situation when the overall water transport is limited by interfacial vaporization exchange. For kpem 1. bulk water permeation in the PEM is the limiting process. For a given type of membrane, a critical thickness IpEM can be defined, which marks the transition between these two regimes, as will be shown below. As noted in Monroe et al. (2008), the condition kpem 1 does not imply that absorbed water at the surface of the PEM attains equilibrium with water vapor in the gas.
