Determination of rhodium by thermal neutron activation analysis using g-ray spectrometry
(Elsevier, 1962)
Trace amounts of rhodium have been determined by thermal neutron activation analysis using both destructive and non-destructive methods. With a neutron flux of 1012 n cm-2 sec-1 the lower limits of detection are about 0.1 ...
Carbamyl phosphate synthesis in Nuerospora crassa I. Preliminary characterization of arginine-specific carbamyl phosphokinase
(Elsevier, 1965-08-24)
An enzyme from Neurospora crassa which catalyzes carbamyl phosphate formation is reported. Carbamyl phosphate formation by the enzyme is hown to be dependent upon ATP, ammonia, bicarbonate, and magnesium ions. Glutamine ...
The steady-state relaxation time and the product at equilibrium
(Elsevier, 1967-07-11)
1. 1. According to and his co-workers, the steady-state relaxation time (i.e. the reciprocal of the first-order process by which an enzyme reaction reaches equilibrium) determines, in part, the apparent metabolic flow ...
The effects of the administration of sodium benzoate and diethylstilbestrol disulfate on the hepatic levels of several glucocorticoid-sensitive enzymes in adrenalectomized rats
(Elsevier, 1967-11-14)
1. 1.|In a previous study the administration of benzoate, [alpha]-naphthoate, diethyl-stilbestrol disulfate and various aromatic carboxylic acids to adrenalectomized rats was shown to increase hepatic tyrosine transaminase ...
Technetium chemistry, oxidation states and species
(Elsevier, 1967-03)
Pertechnetic and perrhenic acids behave as very strong acids, Ka ~ 108. Their extensive dehydration to M2O7 in such media as 7 M sulphuric acid complicates a spectrophotometric comparison of acid strengths. Chloroform ...
The integral Hellmann-Feynman theorem applied to hydrogen peroxide
(Springer-Verlag, 1967-01)
Polarographic reduction of pyridinium ion in pyridine tetraethylammonium perchlorate as background electrolyte
(Elsevier, 1966)
Tetraethylammonium perchlorate, compared to lithium perchlorate as background electrolyte for the reduction of pyridinium ion in pyridine, is effective over a wider potential range, but is more difficult to obtain in a ...
