The response on the continental shelf of a baroclinic ocean to
driving by an alongshore coastal wind stress and by barotropic and
baroclinic wind forced interior motions is studied as a function of
latitude. The relative excitation of continental shelf waves and
internal Kelvin waves is studied.
The response of...
Studies were conducted over a two year period to evaluate alternative
finishing methods for spring and fall-born beef cattle. Management
alternatives from birth to slaughter included season of calving, lactating
cow nutrition, preweaning calf nutrition, weaning age, calf and
yearling winter nutrition, range and irrigated pasture supplementation,
grazing practice, range...
Local adaptation in plants may hold the key to understanding the level of resilience of an ecosystem and probability of persistence of a species in the face of rapid anthropogenic changes in climate and disturbance regime. Clonal species are especially important in wetlands, one of our most productive and vulnerable...
This was an experimental study designed to compare the effectiveness
of computer-assisted laboratory instruction to teacher-assisted
laboratory instruction based on student achievement in Elementary
Business Statistics. Computer-assisted laboratory materials and an
Elementary Business Statistics achievement test were evaluated.
Procedures
The setting of this experiment was at Southern Oregon State
College,...
The F13L protein is the major envelope antigen of vaccinia virus, the prototypic member of the Orthopoxvirus genus. F13L is 372 residues in length and is essential for the formation of wrapped forms of virus. F13L contains a number of potential functional domains including a palmitylation site, a phospholipase domain...

This study is a synthesis of the available ethnographic and relevant archaeological data pertaining to the Native American groups who formerly occupied the upper Rogue River drainage of southwestern Oregon. The information presented in this synthesis concerns the material, social and religious aspects of aboriginal life as practiced by the...
Factors that influenced the uptake, storage, and elimination of dietary quinoline by rainbow trout (Salmo gairdneri) were studied to obtain an understanding of the mechanisms affecting the bioaccumulation of dietary contaminants in teleosts. Rainbow trout readily absorbed ¹⁴C-quinoline from pelleted food (1% ration at 138 ug quinoline/g food) and most...
A post-failure investigation of a highway embankment constructed
over organic and sensitive subsoils was made with a series
of field vane tests. The results indicated that the embankment was
quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...
Eight scale characters of known hatchery and wild coho salmon
(Oncorhynchus kisutch) were compared, and a linear discriminant
function was used to determine if hatchery and wild adult coho
salmon could be correctly identified by their scales. Eighty-two
percent of the hatchery and 89% of the wild fish were correctly...
Vacuum evaporated dielectrics for use in MOS structures
were studied in this research project. Dielectric
films were deposited on substrates by electron bombardment
evaporation of sapphire and quartz source materials.
These deposited films were studied using infrared spectroscopy,
index of refraction, density, and dielectric constant
measurements. Etching tests were also...
Urban forests are fundamental to the health and sustainability of urban communities. In 2012, the U.S. Forest Service launched the Vibrant Cities, Urban Forests: A National Call to Action initiative which posed a variety of recommendations to advance urban forest management and programs throughout the country. In response to that...
Describes the symptoms and damage caused by silver scurf, a fungal disease of potatoes. Includes color photos of symptoms. Discusses sources of inoculum and the disease life cycle. Suggests management practices (seed selection, crop rotation, seed treatments, management of die-down, sanitation, harvest, and storage) to minimize disease problems.
The number of drones and genetic diversity among drones are
essential components to a well mated queen. Varroa destructor
preferentially parasitizes drone brood, and is thought to be
responsible for the loss of feral populations that once provided
additional drones for honey bee mating areas. It is necessary to
use...
Data were taken from 47 animals consisting of five
breeds: Border Cheviot, Columbia, Dorset Horn, Suffolk,
and Willamette. Both sexes were represented in each breed,
although in unequal numbers. The pituitaries were assayed
for gonadotropic and thyrotropic hormone content by injecting
a suspension of the macerated gland in saline into...

The objective of this study was to investigate the effect of inorganic
and organic components of molasses on the laxative problem
encountered when molasses makes up a large portion of livestock
rations. In a series of four trials 280 male Long Evans rats weighing
approximately 50 grams each were placed...
Direct measurements of vertical water motions were made in
the Oregon coastal region during the 1972 summer upwelling season.
The instruments used were the Webb-Voorhis vertical current meters
which are freely drifting neutrally buoyant floats capable of sensing
vertical motion. It was found that in the region studied, water tended...
