The competition or rivalry for the use of water resources
among economic sectors of the Pacific Northwest and among geographical
regions of the western United States has intensified in recent
years. This rivalry and the long run prospects for water shortages
have increased the demand for research concerning the productivity...
Past research has implied that differences in blender performance
between commercial and laboratory particleboard blenders
may not be attributed to resin distribution between screen fractions,
as is commonly believed in the industry today, but to which particles
within a screen fraction have resin and which do note
To test this,...
This thesis is an attempt to develop a theoretical microeconomic
model which can be used to examine the short-run demand for the
timeliness of farm machinery repairs. This analysis focuses on
the timing of the repair after a breakdown has occurred.
The nonstochastic model developed allows the incorporation of
the...
The objectives of this study include: (1) analysis of Chamaecyparis
lawsoniana, C. taiwanensis, and C. formosensis forests including
the structure, composition, and dynamics of plant communities and
their environmental relationships; and (2) comparison of the temperate
Chamaecyparis forests of Taiwan and the Pacific Northwest with emphasis
on structural and successional...
The Oregon sockeye salmon virus (OSV) was isolated from
diseased sockeye salmon (Oncorhynchus nerka) fingerlings in 1958
by J. L. Fryer. Experimentation performed prior to the research
reported herein indicated that the OSV contained essential lipids, was
100 to 300 mμ in size, and possessed RNA (presumptively identified
by 5-bromodeoxyuridine...
The study resulted from a desire and interest to include computer
simulation techniques in the design of educational practices.
The purposes of the study were (1) to develop a computer model which
would simulate the service functions of a counseling center by tracing
students through the center and (2) to...
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...
Porapak Q, Chromosorb 102, and Tenax GC, three porous
polymers commonly used as adsorbents in headspace analyses were
investigated. The retention times of various low-boiling compounds
relative to water were measured on the collection columns to determine
which compounds would be lost during the water removal step
employed after sampling...
