A series of four trials were conducted to determine the influence
of selenium supplementation of a selenium- and vitamin E-deficient
basal diet on the absorption, excretion, tissue distribution
and placental transfer of a single dose of tritium-labeled α-tocopherol
in the rat.
In the first trial, the effect of supplementation of...
As the management of range lands is intensified or as improvement
activity is increased, a critical need is seen to refine the
understanding of the ecology of these lands. If soil surveys on range
lands are to be meaningful and useful, the relationship between the
fundamental ecological units and the...
The objective of the thesis was to determine the effects of
isolated coumestrol on the growth, carcass characteristics and
certain organs of wether lambs. The first of two trials was conducted
over an eight week period with two groups of heavy wether
lambs. Trial two was conducted over an 11...

The purpose of this study was to develop means to facilitate
the detection of staphylococcal enterotoxin and to elucidate factors
that influence enterotoxin formation. It was found that semipurification
flat-gel electrophoresis in a water-cooled apparatus
was more efficient than CM-cellulose and Sephadex column chromatography
currently used to separate toxin from...
The taxonomic placement of Gadopsidae is discussed and an evaluation of its osteological relationships with related families is given. Similarities to the more primitive genera of the trachinoids, notothenioids, and uranoscopoids are noted and the inclusion of Gadopsidae in the Trachinoidae is recommended. A description of the geological history of...
The diffusion coefficients of several chlorinated hydrocarbons
in air were determined by using an Arnold cell. The chlorinated
hydrocarbons used were carbon tetrachloride, chloroform, 1, 2-
dichloroethane and dichloromethane. To determine the reliability
of the experimental method, diffusion coefficients were obtained
for benzene and ethanol. These were compared with diffusion...
