A Critical Discussion on Bath-tub Curve
The typical bathtub curve and its “standard”shape have been widely accepted as an engineering tool in reliability management and training. However, some recent researches reveal that the typical theory of ‘bathtub curve’is not so convincing in some situations. Therefore, a critical discussion is developed to research the bath-tub curve along three significant periods of bath-tub; i.e. infant mo...
متن کاملStudies on Tubercle Bacillus-histiocyte Relationship
Studies of passive transfer of cellular resistance, as manifested by refractoriness to necrotization with virulent tubercle bacilli, have shown that immune histiocytes or immune lymphocytes were effective transferring agents; immune polymorphonuclear leucocytes and immune serum as well as comparable cells from normal animals lacked this capacity. Comparisons of immune histiocytes and immune lym...
متن کاملStudies on Tubercle Bacillus-monocyte Relationship
Studies of the conditions necessary for maintenance of constant cell populations in vitro in the Mackaness type of culture chamber have indicated the importance of preliminary trypsinization of cells and the beneficial effect of 40 per cent rabbit serum in Tyrode's solution. Under these optimal conditions, uninfected suspensions of monocytes exhibited little change in cell numbers over a period...
متن کاملCatalytic studies on tryptophanase from Bacillus alvei.
Tryptophanase from Bacillus alvei exhibited the expected spectrum of pyridoxal-5'-phosphate-dependent reactions. It exhibited l-serine dehydratase, S-alkyl-cysteine lyase, and cysteine desulfhydrase activities, as well as the classic tryptophanase reactions (all beta elimination reactions). It also acted as a tryptophan synthetase (beta replacement reactions) using indole plus l-serine or l-cys...
متن کاملStudies on Bacillus Typhosus Toxic Substances
A phenomenon of local skin reactivity to B. typhosus culture filtrates is described in this report. The reactivity was induced by skin injections of the filtrate followed 24 hours later by an intravenous injection of the same filtrate. The local response consisted of severe hemorrhagic necrosis and was fully developed 4 to 5 hours after the second injection. About 78 to 79 per cent of the rabbi...
