## Abstract A new apparatus for the determination of vapor permeability of volatile liquid substances through polymer membranes has been described. The permeability of the vapor is calculated from the measurements of the depression rate of the liquid meniscus in a calibrated capillary tube. The con

## Abstract The biocompatibility and high gas transfer characteristics of gas‐permeable membranes have led to their use for total and supportive cardiopulmonary bypass. The gas transfer rates, particularly of oxygen, have previously been measured with sophisticated apparatus and this has restricted
## Abstract Two methods for estimating the microsecond–millisecond dynamics in proteins from only two ^15^N relaxation parameters at one magnetic field strength are investigated. Thus, the chemical exchange contribution, __R__~ex~, to the transversal relaxation rate, which contains the dynamics inf
A new fluorescence method has been developed to measure simultaneously and independently the release of fluorophores from two vesicle populations. Calcein and sulforhodamine B were used as a probe couple: the leakage of these probes from vesicles can be recorded independently since they can be excit
