The diffusivities of volatile hydrocarbons in semi-solid Athabasca bitumen were determined by a technique which involves diffusion of hydrocarbon from a bitumen-hydrocarbon solution into a flowing stream of nitrogen. The diffusion method developed is new and can be used for the determination of the

โฆ Synopsis
Rejuvenation of polluted stream beds or muds is important not only for bringing a once healthy stream back to life, but also for the aquatic life and humans that directly or indirectly are exposed to it. The study reported here deals with an experimental study of diffusivities through soils and calculation of hindrance factors. Such information provides a basis for predicting rejuvenation rates of polluted muds.

A modified method for determination of diffusivities of low molecular substances in non-Newtonian liquids described by the power-law model has been proposed. It is based on the dissolution of Geiss body, with a parameter m = 1/3 rotating in an infinite fluid. In this case, the solution of the differ
