چکیده
Measurements of the transport properties of cellulose membranes for the mixtures methanolwater and formamide-water are reported. The measured approach of the mole fractions of the nonelectrolyte to its equilibrium value are interpreted in the framework of linear irreversible thermodynamics in a novel way. The permeabilities of the membranes of the different substances are discussed in terms of phenomenological coefficients. It is shown that these depend on the equilibrium mole fraction in an essential way. A discussion of this effect is given.

Fr. Kaiser and M. Wagner Institute of Theoretical Physics, University of Stuttgart (Z. Naturforsch. 32a, 375-382 [1977] ; rceived March 17, 1977) The Peierls-Boltzmann transport equation for phonons is re-formulated and modified by means of sequences of transport and statistical postulates. The transition probabilities within the collision term are expanded in a comprehensive way. The resulting...

Transport-relaxation equations for seventeen moments are derived from the linearized Boltzmann equation for a monatomic gas. Besides the well-known thirteen moments (i. e. density n, tempera ture T, velocity v, heat flux q, friction pressure tensor p), one additional scalar A and one ad ditional vector A are taken into account. In steady state, differential equations for T, v, A and constitut...

The Method of Model Microfields proposed by Brissaud and Frisch is applied to calculate Stark broadened profiles of hydrogen lines in the static ion approximation. Numerical results for L-a, H-a, and H-ß are found to be in good agreement with those derived from the unified theory by Vidal, Cooper, and Smith over a wide range of plasma densities and temperatures. This demon strates that reliabl...
