The bioavailability and pharmacokinetics of theophylline
in rabbits were determined following both oral and
intravenous administration of the drug. Serum theophylline
concentrations were determined using high pressure
liquid chromatography. Pharmacokinetic parameters were
determined and verified by computer analysis. The overall
mean Beta disposition constant was 0.089 hr⁻¹ which corresponds
to...

how well programs of cooperative education are functioning in meeting
the needs of pupils and the community through a survey of those
programs in selected high schools in Oregon, and (2) To develop

In the study of gas chromatography a model is presented to simulate
a capillary gas chromatographic system. The model was developed
to study the concentrations of sample gas as a function of time and
space as it travels through the capillary column. The molecular migration
was approximated by elementary diffusion...

Pre-harvest foliar desiccation of Yellow Globe Danvers onions was
investigated as a means to improve harvest procedure and to reduce
storage losses. Foliar desiccation tended to increase storage disease
and sprouting incidence versus the untreated controls. Paraquat
approximately doubled storage disease in both years. Stoddard solvent
and ethephon increased disease...
