The erythrocyte membrane proteins of patients with pseudohypoparathyroidism type l and healthy volunteers were analysed by two-dimensional polyacrylamide gel electrophoresis in combination with a sensitive silver staining method. Electrophoretograms from patients were invariably different from control separations with respect to at least three protein spots. The possible relationship with the r...

Fermentations provide an alternative to fossil fuels for accessing a number of biofuel and chemical products from a variety of renewable and waste substrates. The recovery of these dilute fermentation products from the broth, however, can be incredibly energy intensive as a distillation process is generally involved and creates a barrier to commercialization. Membrane processes can provide a lo...

The nominal directivity for uniformly spaced broadside parallel half-wave dipoles associated with a uniform excitation is evaluated. The amplitude distribution for an optimized directivity is then obtained for different numbers of elements with the separations between the dipoles as a variable. The optimum and nominal directivities are compared for different spacings of the elements. While thes...

In several processing industries, separation of different components from a mixture is an important unit operation. Sometimes the separated component is an important product, and in some instances it is a waste product. There is a variety of technologies available for use in separations, each operating based on physical and chemical properties of the mixture. One of the fundamental separation p...

Hydrophobic thickness mismatch between integral membrane proteins and the surrounding lipid bilayer can produce lipid bilayer thickness deformations. Experiment and theory have shown that protein-induced lipid bilayer thickness deformations can yield energetically favorable bilayer-mediated interactions between integral membrane proteins, and large-scale organization of integral membrane protei...
