    Notizen: Examination of a nase Chondrostoma nasus, that was carrying an implanted telemetry transmitter for 7 months, showed that the external trailing antenna of the transmitter had migrated c. 3 cm to the posterior edge of the incision. The absorbable sutures were still present, and there was epithelial tissue within the granulation encapsulating the transmitter. This tissue may have grown down from the surface along the antenna providing a potential entryway for pathogens.

    Notizen: Thirty one mirror carp Cyprinus carpio were implanted with telemetry transmitters. Several large scales were removed from the incision area of two mirror carp before implantation of transmitters. When the fish were recaptured after 4 months, the mirror carp from which scales were removed showed severe tissue necrosis at the incision site whereas intact fish did not.

    Notizen: Abstract About 160 mutants of Schizosaccharomyces pombe with altered activity of the nonspecific acid phosphatase located on the cell surface were isolated. The following kinetic parameters were determined by automatic techniques on the mutants: (1) residual activity vs. wild type, (2) K m , (3) V max , (4) optimal pH, (5) percent pH curve. The ability of the various parameters to discriminate between genetic variants was investigated by applying to the results a suitable statistical quantitative index, R (resolving power), previously defined by us. The last two parameters had least resolving power, whereas the first three had about equal resolving power. This was found to be consistent with current concepts of enzyme and protein structure. These results could serve as guidelines in the choice of biochemical parameters for the study of polymorphisms in systems not previously investigated. Moreover, they provide information about the relative effects on the various parameters of mutations which give rise to the genetic variants and also about the molecular nature of mutations occurring at different loci involved in the control of acid phosphatase in S. pombe.

    Beschreibung / Inhaltsverzeichnis: Securing screws of stainless steelsThe author emphasizes the importance of screwed connections in technology and discusses the conclusions which must be drawn from existing standards with respect to the utilization of stainless steel screws. Examples are shown to demonstrate the corrosion resistance of such connections (tests in sea water, 3% NaCl, tap water, salt spray) giving prominence to the problems resulting from the use of spring elements (crevice corrosion danger).
    Notizen: Der Verfasser betont die Bedeutung der Schraubenverbindungen in der Technik und erörtert die Folgerungen, die sich aus den bestehenden Normen für die Anwendung von Schrauben aus nichtrostenden Stählen ergeben. Anhand won Beispielen wird die hohe Beständigkeit solcher Verbindungen demonstriert (Versuche in Meerwasser, 3% NaCly Leitungswasser, Salzsprühnebel), wobei besonders die Probleme aufgezeigt werden, die sich durch die Verwendung federnder Elemente ergeben (Spaltkorrosion).
