Neutron flux and gamma-ray dose have been measured in the
experimental facilities of the Oregon State TRIGA reactor.
Thermal neutron flux measurements utilized foil activation
techniques.
The gamma-ray dose was measured with a thermoluminescent...

In the arid western United States, wildlife water developments, or ‘‘guzzlers,’’ are important water sources
for wildlife, and consist of impermeable roof structures designed to intercept precipitation and small tanks for
storing water. Guzzlers...

During a study of the abnormal dienone-phenol rearrangement
discovered by Marvell and Geiszler, Imel (1960) found that 4-oxo-3,3-dimethyl-3,4-dihydrophenanthrene rearranged slowly to a phenol
which was tentatively identified as...

A cytogeographic study, the relationship between chromosome
number and geographical and ecological distribution, was made of the
tetraploid and hexaploid chromosome forms of Achillea millefolium L.
in western Oregon. Principal objectives of the...

The fishes of Upper Klamath Lake appeared to distribute
themselves in three general groups during the summers of 1964
and 1965: (1) the chubs--unrestricted as to distribution with slight
seasonal variations; (2) rainbow trout and yellow perch --...

The regulation of ergosterol biosynthesis in yeast has been
studied. The system has been examined for the presence of an end-product inhibition. Both anaerobically and aerobically grown cells
have been examined for this effect. A feedback...

Abundant conidial and sclerotial production occurs on iris
plants infected with Botrytis convoluta Whetzel and Drayton during
the cool moist months of the year. Experiments were designed to
study the survival and inoculum potential of conidia and...

In response to a question raised by Knox
Lovell, we develop a method for estimating directional
output distance functions with endogenously determined
direction vectors based on exogenous normalization constraints.
This is reminiscent of the...
