Abstract: A hydrodynamic slide bearing (10, 10?) supports a shaft (14, 14?) that is mounted rotatably. The hydrodynamic slide bearing (10,10?) comprises a plurality of bearing segments (12, 12?) arranged next to one another in the rotation direction (22, 22?). The segment surfaces together form a running surface (16, 16?) for the shaft (14, 14?). At least one bearing segment (12, 12?) has a plurality of grooves (26, 26?) disposed in its segment surface, and the grooves (26, 26?) are orientated substantially transverse to the rotation direction (22, 22?). The rear groove edges (261) in the rotation direction (22, 22?) are orientated obliquely to their respective assigned radial plane (24, 24?) and are undercut in relation to their respective assigned radial plane (24, 24?). The front groove edges (262) in the rotation direction (22, 22?) are not undercut and are orientated obliquely to their respective assigned radial plane (24, 24?).

Abstract: A process for the inactivation and/or elimination of coated and/or noncoated viruses from a plasma protein solution by addition of an ammonium salt at alkaline pHs is described, in which a chromatographically prepurified plasma protein solution is subjected to an incubation at room temperature and at an ammonium salt concentration of 13 to 22% by weight, pasteurized at approximately 60° C. for several hours after separation of the precipitates and removal of the ammonium salt down to a residual content of less than 0.5 mol/l and then processed to give a therapeutically employable plasma protein preparation.
