## Abstract An apparatus based on a differential gasβchromatographic detection system was designed in order to obtain information about the average permeation coefficient for pervaporation (PVAP) of pure liquids through isotactic poly(propylene) (iβPP). The nonβideal concentration dependence of dif

Crystallization of drugs in metastable, supersaturated adhesive polymeric matrices in transdermal drug delivery devices can be avoided by determination of the solubility of the drug in the adhesive polymer. A novel method is described to determine the solubility of the drug in polymeric matrices. Un
## Abstract Soil cores from river marginal wetlands from the Torridge and Severn catchments in the UK were collected to study rates of soil denitrification at different sites and at two stations (levee and backplain depression) at the river margin. Half the cores were sterilized prior to flooding t
## Indirect Mothods of Calculating Ternary Diffusion Matrix We siimmarised, in part one of this paper, procedures of measuring diffusion matrix in thrce-component single phase alloys direct from the concentration-distribution profiles in infinite diffusion couples. In this paper (Part XI) some pro
## Abstract A new experiment for the singleβscan measurement of diffusion coefficients is presented. The principle is to introduce a spatial variation in the parameters of a conventional pulse sequence, so that all of the scans required to determine some physical parameter can be recorded simultane
