The inhibition of phosphoribosyl-pyrophosphate amidotransferase activity by cordycepin monophosphate
(Elsevier, 1964-09-18)
1. 1. Cordycepin monophosphate has been shown to inhibit the activity of phosphoribosyl-pyrophosphate amidotransferase (ribosylamine-5-phosphate:phyrophosphate phosphoribosyltransferase (glutamate-amidating), EC 2.4.2.14) ...
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 ...
Autoradiography with acrylamide gel slab electrophoresis
(Elsevier, 1969-04)
A method for electrophoresis and autoradiography with a multisample gel slab system has been described. The method obviates slicing of the gel, retains the high degree of resolution of bands in the autoradiogram, and enables ...
Force fields for nitriles
(Elsevier, 1968-11)
A valence force field for nitriles based on the force field obtained for hydrocarbons is found to give very good agreement with the observed bands for several mono- and di-nitrile molecules. The average deviation between ...
Studies on the estimation of deoxyribonucleic acid and ribonucleic acid in rat brain
(Elsevier, 1963)
A method for the estimation of DNA and RNA in rat brain is described. The principal modifications of preexisting methods involve initial lipid extraction with chloroform-methanol and continuous stirring during alkaline ...
Thermal cracking of ethane and ethylene in a stock tube
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1962-05)
The rates of decomposition of ethane and ethylene were measured at temperatures between 1,250° and 2,800°K. and pressures between 0.25 and 2.0 atm. by exposing the gases to high temperature during the interval between the ...

Photosynthetic membrane development in Rhodopseudomonas spheroides: Incorporation of bacteriochlorophyll and development of energy transfer and photochemical activity
(Elsevier, 1969-10-21)
1. 1. Bleached cells of Rhodopseudomonas spheroides, obtained by aerobic growth in the light, rapidly synthesize bacteriochlororphyll and carotenoids when transferred to 4% oxygen in the dark. Fluorescence excitation spectra ...
