Abstract

A well‐mixed biological reactor with continuous addition of biological solids was subjected to sinusoidal variations in inlet substrate concentration. The phase lag between inlet and outlet concentrations increased with increasing frequency. The deviation of measured substrate concentrations from initial steady‐state concentrations was observed to have a maximum near a frequency of 1 cycle per residence time. Measured concentrations of substrate and biomass in the reactor differed significantly from concentrations predicted by the Monod kinetic model.

The performance of a packed-bed biological reactor has been analysed under sinusoidal variations of substrate concentration and temperature for zero-order, first-order and Michaelis-Menten kinetics. The model equations were solved by the method of orthogonal collocation. The results show that the cy

The effects of concentration and dose volume on the nasal bioavailability and biological response to desmopressin [DDAVP; 1-(3-mercaptoproprionic acid)-8-D-arginine vasopressin] were investigated in humans. A nasal formulation of 300 micrograms of desmopressin was administered using a premetered spr
