چکیده
Recently a reciprocity theorem has been derived from the transport-relaxation equations for a simple system, consisting of one medium (Ref . ' ) . With a composite system, consisting of two immiscible media in contact, a plausible generalized reciprocity scheme, here called universal reciprocity postulate, is suggested now. It leads to an equivalent reciprocity requirement at the interface between both media and thus decisively restricts — in form of provable Onsager relations — the possible constitutive laws connecting the thermodynamical forces and fluxes at the interface. For the formulation of these ideas, some mathematical tools are developed in advance. Finally, heat conduction is treated, as the most simple example, first in the direct way, then according to the more sophisticated mathematical tools.

A rigorous non-existence proof for runaway solutions in the finite-size model of the electron is given. Since a consistent point limit, such as the Lorentz-Dirac equation claims to be, should not exhibit features which are completely missing in the more general theory of finite extension, it is proposed that the point-like approximation of the finite-size theory be the integrodifferential formu...

A tobacco-like odorous compound isolated from a bloom of the blue-green alga M icrocystis w esenbergii and a laboratory culture of M. aeruginosa was analysed by gas-liquid chromatography and mass spectrometry. Its structure was determined as /?-cyclocitral. No other monoterpenes have been detected in these and in other blue-green algae. The hydrocarbon content was 0.10 — 0.18% of the dry weight...

(Z. Naturforsch. 31a , 1 3 0 [1976 ] ; received November 14, 1975) During collisions of heavy ions with heavy targets below the Coulomb barrier, adiabatic molecular orbitals are formed for the inner electrons. Deviations from adiabaticity lead to coupling between various states and can be treated by time-dependent perturbation theory. For high charges ( Z 1 + Z 2 60) the molecular electrons are...
