Nitrogen is a contaminant of niobium and tantalum adversely
affecting the workability of the metal. With recent interest in the
refractory metals, one problem the chemical analyst must solve
is the accurate determination of nitrogen in niobium and tantalum
at very low levels. The usual method of assaying for nitrogen...
The catabolism of glucose by proliferating and resting cells of
two strains of Saccharomyces cerevisiae has been examined, with
respect to the nature and participation of concurrent glucose pathways
by means of the radiorespirometric method. The nicotinamide
nucleotide content, and nicotinamide nucleotide oxidase activities
in these cells were also examined....
