Determination of metal cyanide and thiocyanate complexes by kjeldahl-gunning and carius sealed tube digestion methods
(Elsevier, 1960)
Small amounts of metal cyanide and thiocyanate complexes can be determined using either the Kjeldahl-Gunning or Carius sealed tube digestion method. The results obtained by the Kjeldahl-Gunning method are somewhat low and ...
Detonation characteristics of hydrogen-oxygen mixtures at high initial pressures
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1960-09)
Detonation velocities of hydrogen-oxygen mixtures were measured for initial pressures from 14.4 to 1,000 lb./sq. in. abs. and compositions from 40 to 80 mole % molecular hydrogen. Detonation and impact characteristics were ...
Activation-analysis of trace cobalt in tissue using 10.5-minute 60m-cobalt
(Elsevier, 1960-01)
Microgram amounts of cobalt from vitamin B12 have been analyzed by rapid activationanalysis in rat kidney tissue as well as in vitamin preparations. A 15-minute radiochemical separation procedure coupled with gamma-ray ...
The destruction of indoleacetic acid. III. Relationships between peroxidase action and indoleacetic acid oxidation
(Elsevier, 1960-03)
The indoleacetic acid (IAA)-oxidizing enzyme preparation from Omphalia flavida exhibits peroxidase activity on pyrogallol with an optimum at pH 3.5-3.7, like that for the IAA-oxidizing activity. It shows no polyphenolase ...
