In order to help validate the free-living roundworm, C.e., as a simple model to study the mechanism of general anesthesia, we demonstrated that homologous series of alcohols and alkanes produced a reversible "anesthetic" effect in these worms as in o

By means of temperature-dependence studies of e.s.r. spectra it has been found possible to distinguish between the wool signal and the dye signal when dyed wool is subjected to ultra-violet irradiation. Two different observable patterns of behaviour

After a study of the photochemistry of wool keratin, a mechanism is proposed for the reactions that lead to the sunlight yellowing of wool. The involvement of singlet-excited oxygen is confirmed by both direct and indirect methods.

The e.s.r. spectra obtained by 310 nm irradiation of a range of dyes of different chemical structures in nylon film was found to be due entirely to the dye. From an examination of the temperature dependences of these e.s.r. responses it has been dedu

The photochemical behaviour of four reactive-azo dyes, (two dyes with poor wet light fastness and two dyes with normal wet light fastness) was examined to elucidate the mechanisms by which some reactive azo dyes, applied to cellulose, fade more rapid

— By comparing the photochemical behaviour of tryptophan and N'-methyl tryptophan, both in the free state and protein bound, evidence has been obtained which indicates that indole N—H bond fission is a primary photochemical reaction during the ph

The proportion of disordered (amorphous) material in wool may be assessed by exposing a sample of known dry weight to saturated deuterium oxide vapour and expressing the gain in dry weight, duo to the hydrogen deuterium exchange reaction, as a fracti

The yellow discoloration produced by drying wool containing alkali at elevated temperatures has been shown to be dependent on the the time and temperature of drying and the presence of strong alkali. The presence of mild alkali, such as sodium carbon
