A study of low molecular weight asphaltic hydrocarbons
(1965)
Hydrocarbon fractions from three road building asphalts were isolated. The first step was precipitation of the asphaltenes with n-pentane. The petrolenes were then treated with sulfuric acid, followed by chromatography of ...
Bioassay of residues of endrin, diazinon, carbaryl, and naled on sorghum grain
(1965)
The objective of the study was to evaluate the efficiency and suitability of biological analyses of residues of endrin, diazinon, naled, and carbaryl insecticides on sorghum grain. Two methods of biological assay were found ...
The influence of calcium, sulfur, moisture, and temperature on the fiber development of snap beans
(1965)
Two different greenhouse experiments were conducted to determine the influence of some environmental factors on the increment of the fibrous sheath in the green snap bean pod, using Wade variety. Fiber was determined by ...
The effects of epithermal neutron flux anisotropy on cadmium correction factors
(1965)
The effects of epithermal neutron flux an isotropy upon the cadmium correction factor F[subscript cd] have been determined both theoretically and experimentally for indium foils in a water medium. Spencer's and Fano's ...
Absorption of resonance scattered gamma-rays as a method of measuring nuclear level widths
(1965)
A novel method for determining nuclear level widths is used in this investigation. Neutron capture gamma-rays from iron bombard a lead target. The incident 7.285 Mev gamma-rays cause resonance fluorescence of the Pb²⁰⁸ in ...
