Juvenile coho salmon (Oncorhynchus kisutch) were orally
immunized against the bacterium Flexibacter columnaris (formerly
Chondrococcus columnaris), the causative agent of columnaris disease
in fish, with a vaccine-food preparation containing formalin-killed
cells. Fish immunized for 1, 2, 3, and 4 months were challenged
with selected concentrations of F. columnaris by exposure...
Mathematicians have been concerned with population growth
and movement since the days of Leonhard Euler and Thomas Malthus.
Chapter i of this paper sketches the history of the development of the
modern population theory.
In Chapter II, a partial differential equation is derived which
governs the growth and movement of...
This thesis describes a Mossbauer effect and electron
paramagnetic resonance study of iron (III) tetraphenylporphyrinatobenzenethiolate
benzene thiol, an analog compound
for bacterial cytochrome P-450. The compound is unusual in
that it provides a model for the two ferric reaction states
of cytochrome P-450. The iron in the model compound exhibits...
Few Americans are aware of the tremendous
recreation potentials along the banks of the Intracoastal
Waterway, mainly because they are unaware of
the existence and extent of the toll-free Waterway.
This study attempts to categorize and locate some of
the attractions that can be explored along the two
thousand miles...

and Willamette Rivers in Polk and Marion Counties, Oregon,
It is situated on a peninsula supporting riparian and lower
terrace vegetation and associated wildlife. Former use
included forestry and agriculture. Present and proposed use...
The physical characteristics and spatial location of
land are hypothesized to be significant inputs to its
valuation. This research evaluates the influence of
locational, economic, and physical site variables on the
assessed value of real property.
Evaluation of such influences is based on a stratified
systematic sample of land parcels...
