Bioluminescence as noise in an underwater optical surveying device
(1965)
The effect of a pulsed light in the stimulation of bioluminescence by organisms at the 700 meter depth in the Northeast Gulf of Mexico has been studied. The instrument consisted of pulsed xenon lamp source and a photomultiplier ...
Far infrared and nuclear magnetic resonance spectra of molecules with internal rotor groups
(1965)
The torsional frequencies for 1,2-butadiene, methyl phosphine and 1-chIoro-1, 1-difIuoroethane were observed in the far infrared at 153.9, 207 and 246 cm⁻¹ respectively. The corresponding barriers to internal rotation were ...
A characterization of the lipids of the organisms which make up the main bulk of a coral reef with particular emphasis on the hydrocarbons
(1965)
The lipid extracts of a series of living and fossil reef organisms were subjected to analysis by a variety of techniques. Initial column chromatography over silicic acid gave a series of fractions: 1. Saturated and monenoic ...
Transient thermal stresses in liquid metal cooled reactor fuel elements
(1965)
A numerical solution for two-dimensional transient thermal stresses in a liquid metal cooled nuclear reactor fuel element is presented. The method consists of first determining the two-dimensional transient temperature ...
Correlations between structure and nuclear magnetic resonance (N.M.R.) spectra for aliphatic esters
(1965)
The n.m.r. chemical shift for 18 acetate esters, CH₃COOR', and 16 methyl esters, RCOOCH₃, have been measured neat and in carbon tetrachloride solution. The n.m.r. chemical shifts of acetate esters, CH₃COOR', are controlled ...
A search for double-minimum potential functions in excited states of bent triatomic molecules
(1965)
The spectra of the 3700-Å absorption system of SO₂, the 2491-Å absorption system of NC₂ and the 1340-Å system of SO₂ are investigated. The principal aim of this study is to find evidence for double-minimum potential ...
A comparison of two techniques of teaching engineering descriptive geometry
(1965)
Statement of the Problem: The purposes of this research were to determine: (1) the effectiveness of self-scoring as an immediate reinforcement to learning using six selected principles of descriptive geometry, (2) which ...
A study of kinetin in plants
(1965)
Since the discovery of kinetin in 1954, the translocation pattern of this plant growth regulator had remained obscure. On the basis of general observation, it has been assumed that kinetin is largely immobile in plants. ...
