Base Effects on the Thermal Decomposition of Sec-butyllithium Solutions

Base Effects on the Thermal Decomposition of Sec-butyllithium Solutions

Date: June 1966
Creator: Adams, George Michael
Description: The pyrolysis of sec-butyllithium in solution was studied in an attempt to understand the loss of stereo-specificity and the atypical kinetics that have been reported. Additionally, the effect of added lithium alkoxides was studied to determine their effects on the highly reactive sec-butyllithium substrate.

A Two-Dimensional Model Study of Elastic Waves

A Two-Dimensional Model Study of Elastic Waves

Date: 1955
Creator: Fulton, Thomas K.
Description: In seismic field operations complex problems often arise which cannot be solved mathematically. In recent years investigators in both the commercial and academic fields have begun to approach the problems of elastic wave propagation by the use of seismic scale models. This thesis discusses the results measured from simulated seismic activity on a scale model built by the researcher.

Experimental Determination of the Scattering Cross-section of Ogives and Prolate Spheroids at Microwave Frequencies

Experimental Determination of the Scattering Cross-section of Ogives and Prolate Spheroids at Microwave Frequencies

Date: 1956
Creator: Rhoads, Wayne C.
Description: Because of the great difficulty of obtaining exact numerical values of cross-section, and because of the inherent uncertainties in interpreting and evaluating the approximate methods, accurate experimental cross-section data would be extremely useful to the radar engineer. It was with this purpose in mind that the present long-range research program in microwave scattering was undertaken. Of immediate interest were the scattering properties of the prolate spheroid, the ogive (formed by rotating the minor segment of a circle around the chord), and, for comparison, the long cylinder.
