    Notizen: Abstract Continuous pathways must pierce the cell membrane to be used by water during osmotic equilibration between proximal straight tubular cells and the external medium, because a) the water osmotic permeability coefficient of the basolateral plasma membrane,P os cb , is high; b) its activation energy,E a, is as that of free water movement and c) pCMBS inhibits markedly (but reversibly)P os cb and increasesE a to values similar to those observed in lipid bilayers without pores. d) Preliminary measurements ofP d the water diffusive permeability coefficient using NMR indicate thatP os cb /P d is near 4–5. The following two observations indicate that a significant paracellular water flow must exist in leaky epithelia. Namely, a) large extracellular solutes are dragged by water in four leaky epithelia: gall bladder, Necturus proximal tubule, rat proximal tubule andRhodnius malpighian tubule. b) The transcellular water osmotic permeability coefficient is smaller than the transepithelial values available in the rabbit proximal straight tubule. This requires a significant paracellular permeability.

    Notizen: A simple transition probability formula is applied to the core hole ionization in CO, satisfactorily predicting the ratio between the intensity of the two inner-shell peaks. The formula is also applied to the full ESCA spectra of water and methane; the theoretical results agree reasonably well with the experiment.

    Notizen: The study of the structure of the electrode-solution interface usually involves the measurement of the differential capacity-potential characteristics of the system. In order to obtain the double-layer parameters from these data, integration and differentiation procedures are required and, for this purpose, the use of computational methods is of great value. Two computer programs have been written for the treatment of data for the adsorption of neutral molecules on electrodes. The programs use the charge density and the electrode potential as the electrical variable, respectively, and, in both cases, the differentiation procedures have been optimized by the use of an adequate numerical function. The advantages of doing a simultaneous analysis on both electrical variables are pointed out.
