The polarographic diffusion coefficient of cadmium ion in 0.1 M potassium chloride
(Elsevier, 1964-04)
The diffusion coefficient of cadmium ion in 0.1 M potassium chloride at 25[deg] was determined by an absolute method. Straight calculations using the equation derived by Jost yielded values which were too high when compared ...
Phospholipid metabolism in the developing liver : I. The biosynthesis of choline glycerophosphatides by liver slices from fetal, newborn and adult rats
(Elsevier, 1969-07-29)
1. 1. The biosynthesis of choline glycerophosphatides was evaluated in fetal, neonatal and adult female rat liver. The two main pathways were assessed by studying the rates of incorporation of [Me-14C]choline and ...
The interplay of steric and electronic factors affecting geometrical isomerism of diaryl ketimine derivatives
(Elsevier, 1960)
The evidence bearing on the mechanism of the Schmidt reaction with ketones is critically reexamined. It is shown that dehydration of an initially formed azidohydrin (I) to a ketiminodiazonium ion (II), which may or may not ...
Lewis acid-base titrations employing megacycle-frequency oscillators : Part III. Preparation, isolation and characterization of some adducts predicted from titration curves
(Elsevier, 1963)
Adducts of stannic chloride with thirteen oxygen bases, isolated as solids from benzene or heptane solution, were characterized by analysis and melting point behavior; several of these are new compounds. Diethyl ether, ...
Carbamyl phosphate synthesis in Neurospora Crassa II. Genetics, metabolic position, and regulation of arginine-specific carbamyl phosphokinase
(Elsevier, 1965-08-24)
The sole demonstrated enzyme of carbamyl phosphate synthesis in Neurospora appears to serve only the arginine pathway. The enzyme is completely absent in arg-3 mutants, which require arginine. While pyrimidine synthesis ...
A proton magnetic resonance study of the system: Di-(2-Ethylhexyl) Sodium Sulfosuccinate--water-n-Octane
(Elsevier, 1968-09)
Proton magnetic resonance (pmr) has proved to be a useful technique for following the behavior of water in the complex equilibria produced when water is added to solutions of di-(2-ethylhexyl)sodium sulfosuccinate, (Aerosol ...
The biological oxidation of 2,2-dimethyloctanoic acid
(Elsevier, 1965-06-01)
The administration of 2,2-dimethyl [1-14C]octanoic acid to rats results in the urinary excretion of four 14C-labeled polar metabolites. Three of these have been identified as 2,2-dimethyladipic acid, 2,2-dimethyl-7-hydroxyoctanoic ...
Predictions of the particle size distribution changes in emulsions and suspensions by digital computation
(Elsevier, 1969-03)
The fundamental Smoluchowski flocculation rate equations including the effects of polydispersity and particle-particle potential energy barrier have been solved for any initial particle size distribution. The procedure for ...
