Adsorption of vapors by silica gels of different structures
(Elsevier, 1952-02)
1. 1. Isothermals were obtained at 25[deg]C. for the adsorption of the vapors of methyl alcohol, ethyl alcohol, n-propyl alcohol, benzene, carbon tetrachloride, hexane, and water by silica gels of different apparent ...
The structural development of a bacterial virus
(Elsevier, 1952)
Bacteriophage precursors have been studied by breaking open infected bacterial cells and examining the intracellular material under the electron microscope. Bacterial breakage was accomplished by means of explosive ...
Mammalian tyrosinase: Effect of ions on enzyme action
(Elsevier, 1952-04)
1. 1. The univalent cations Li+, Na+, K+, and NH4+ have no effect on tyrosinase action.2. 2. The anions, fluoride, chloride, acetate, and oxalate, consistently inhibit the tyrosine-tyrosinase and dopa-tyrosinase reactions. ...
Sarcosine oxidase activity of rat liver tissue: Effect of folic acid deficiency and induced hyperthyroidism
(Elsevier, 1952-11)
The sarcosine oxidase content of hepatic tissue from rats made deficient in folic acid was similar to that of normal rats. This is taken as evidence that sarcosine oxidase activity is not dependent upon the presence of ...
