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 ...
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 ...
Polymerization of vinylcyclohexane with TiCl 3 –Al(C 2 H 5 ) 3 catalysts
(John Wiley & Sons, Inc., 1965-12)
The polymerization of vinylcyclohexane was followed dilatometrically in cyclohexane and n -heptane solvents with TiCl 3 –Al(C 2 H 5 ) 3 as catalyst. In n -heptane constant rates were obtained, while in cyclohexane a ...
Heat transfer to evaporating refrigerants in two-phase flow
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1965-11)
Flow regimes occurring during evaporation of Freon-12 (dichlorodifluoromethane) and Freon-22 (monochlorodifluoromethane) inside five tubes were investigated. Two flow models are proposed, one each for vertical and horizontal ...
Vibrational spectra and assignments for (CH3)2NPF2
(Elsevier, 1965-07)
Infrared and Raman spectra of dimethylaminodifluorophosphine have been obtained for the gaseous and liquid states at room temperature and for the solid at low temperature. Vibrational assignments are proposed based on a Cs, model.
Some properties of nucleic acids extracted with phenol
(Elsevier, 1965-02-08)
Preparations of nucleic acids obtained by extraction of mouse liver, HeLa cells and cell fractions with phenol and deoxycholate have been characterized with regard to the differential solubility of ribonucleic acid and ...
Isolation and separation of inositol phosphates from hydrolysates of rat tissues
(Elsevier, 1965-06-01)
1. 1.An electrophoretic method for the rapid separation of the phosphate esters of inositol is presented.2. 2.It is used, together with ion-exchange chromatography, to establish the presence of inositol di- and triphosphates ...
The production of a linear density gradient by means of a propertioning pump
(Elsevier, 1965-04)
Dynamics of bullet shaped bubbles encountered in vertical gas liquid slug flow
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1965-07)
A theoretical analysis is presented of the liquid film flowing around long, bullet shaped, gas bubbles which characterize the slug-flow regime in two-phase flow through vertical pipe. Integral mass and momentum balances ...
