The occurrence and distribution of fish viruses in Oregon were
determined by the examination of anadromous and fresh water salmonids.
Infectious pancreatic necrosis virus (IPNV) was isolated and
identified from asymptomatic adult coho (Oncorhynchus kisutch) and
chinook (0. tshawytscha) salmon returning to the Columbia River
system. Infectious pancreatic necrosis virus...
The morphology and genesis of soils of the Willamette series
and of some Willamette-associated soils and their relationships to
geomorphic surfaces were studied in an area near McCoy, Polk
County, Oregon. Influences of regional extent, such as climate and
parent material, were related to the soils and landforms. The soils...
The purpose of this study was to investigate the relationship
between a measure of anxiety and academic achievement of freshmen
women enrolled in the University of Northern Colorado (U.N.C.).
One thousand and eighty women, eighty-seven percent of the
freshmen women, were included in this study. All subjects completed
the American...
The substantial increase in resin costs due to the recent energy
crisis, increased public awareness to the problem of free formaldehyde
from boards bonded with urea-formaldehyde resins, and a projected
increase in the production of exterior board have emphasized the need
for new and substitute adhesive systems. One new development...
Nonlocal theories of continuum mechanics are used to model the
fracture behavior of particleboard in tension perpendicular to the plane
of the board. Classical theories of fracture are examined in comparison
to a nonlocal crack solution which has removed the stress singularity
at the crack tip. With the removal of...
Concern over the need to provide open space in communities
for recreation and other uses and to estimate the public values
involved is apparent to regional planners. This need, particularly
evident in natural resource planning, indicates that more sophisticated
analytical techniques be developed.
The primary thrust of this study is...
The effect of soil temperature and soil water suction on the rate
of phosphorus uptake and growth rate of wheat (Triticum aestivum
VILL. ,
Host) was studied.
Plants were grown in perlite slabs
separated from an osmotic solution by a semi-permeable membrane.
Measurements were made at temperatures of 10.0, 18.3,...
The effect of oral contraceptives on urinary and plasma vitamin
B₆ as well as erythrocyte transaminase activities was investigated in
women. Five women who were taking oral contraceptives and four
who were not using these drugs served as subjects. They were
apparently healthy and free from any known metabolic disorder....
