The purpose of this study was to develop a profile
of Christian College physical education faculty members
regarding their academic preparation, professional
experience, and selected duties, as well as to identify
important components of graduate preparation at the
doctoral level for future faculty at these
institutions.
A survey instrument was...
This paper records a series of experiments conducted furing a one-year period to determine the effects of boron upon the growth and fruiting of Marshall and Corvallis strawberries, two of the leading commercial varieties in Oregon. The problem was approached in four ways: (1) applications of dry borax and borax...
The purpose of this study was to examine various host and microclimatic influences affecting the survival and development of the flatheaded fir borer, Melanophila drummondi (Kirby) in Douglas fir, Pseudotsuga menziesii (Mirbel) Franco residues. It also expands current knowledge of the biology, bionomics, life history, ecology, and biotic potential for...
Seedling root fluorescence (SRF) has been used as a test in the USA since 1941 to discriminate Italian ryegrass (Lolium multiflorum Lam.) from perennial ryegrass (L. perenne L.). Generally, roots of Italian ryegrass fluorescece when exposed to ultraviolet light, while roots of perennial ryegrass do not. Presence of fluorescent seedlings...
This thesis reports on the growth and characterization of p-type
pseudomorphic A1GaAs /InGaAs /GaAs modulation doped field effect transistor
(MODFET) structures. A series of different p-type MODFET structures were grown
with a systematic variation of the indium mole fraction and quantum well width of
the InGaAs channel region. Extensive characterization...
Several biochemical tests were studied to determine their
correlation with coagulase activity. The lysozyme test was in perfect
agreement with the coagulase test for the strains studied.
Mannitol fermentation and egg yolk lipase tests were in agreement
with the coagulase test for 96% of the coagulase positive strains.
Sheep red...
A study was made of the infrared absorption spectrum for
cyanate ion in KCl and KBr host lattices containing small amounts of
calcium or barium ion. Both pellets and single crystals were
scanned during the course of this study. The spectra of the barium
or calcium doped crystals contained many...
A theoretical study of the heat and momentum transfer resulting
from a flow of power plant condenser effluent discharged vertically to
shallow, quiescent coastal receiving water is presented. The complete
partial differential equations governing steady, incompressible, turbulent
flow driven by both initial momentum and buoyancy are solved
using finite-difference techniques...
The central purpose of this comparison was to determine the
congruence or difference between two teaching techniques, the television
method and the conventional lecture method as used in teaching
General Hygiene on the freshman college level at Oregon State University.
Sub-problems associated with this study were, (a) the development
of...
An examination of the technical and historical literature
concerning the discovery and development of antibiotics suggests the
possible existence of an era of discovery. This era appears to have
a well-defined beginning (about 1940) and a well-defined close (about
1960). It is the purpose of this dissertation to examine the...
The genus Lopidea Uhler is revised for America north of
Mexico. The relationship of Lopidea to other orthotyline
genera is discussed and it is proposed that the genus
Ilnacora Reuter is the sister group of Lopidea.
Forty-eight species of Lopidea are recognized in North
America, one of which is described...
This publication deals with the development of integrated pest management of insect and mite species that attack pears in southern Oregon. Since about 1900, when the pear industry became firmly established in this area, losses from arthropod pests have been an important and occasionally limiting factor to the continuous production...
Elevated hepatic expression of fatty acid elongase-5 (Elovl5) induces
FoxO1 phosphorylation, lowers FoxO1 nuclear content and suppresses expression of
genes involved in gluconeogenesis. In this report we define the molecular and metabolic
basis of Elovl5 control of FoxO1 phosphorylation. Adenoviral-mediated (Ad-Elovl5)
induction of hepatic Elovl5 in diet induced obese-glucose intolerant...
This dissertation focuses on the behavior of security returns around certain events that occurred in the Saudi stock market. In the first study, we measure and analyze the reaction of security returns around a major horizontal merger that occurred in the banking industry in Saudi Arabia. The objective of this...
Fungal mitospores may function as dispersal units and/ or spermatia, and thus play a role in
distribution and/or mating of species that produce them. Mitospore production in
ectomycorrhizal (EcM) Pezizales is rarely reported, but here we document mitospore production
by a high diversity of EcM Pezizales on three continents, in...
Moderate wine consumption, particularly pigment-rich red wine, is thought by many to be beneficial for the cardiovascular system. Both ethanol and phytochemicals are thought to contribute to this cardioprotective property. Metabolic disturbances associated with overconsumption of food are related to the initiation and progression of many chronic diseases, and cardiovascular...
The effect of four basic liquid fertilizers: Solution 32, 10-34-0-.9, Thio-Sul, and Potash solution; and one commercial liquid fertilizer, Feast 9-18-9, on germination, emergence, and seedling growth of wheat (Triticum aestivum L.) were evaluated under laboratory, greenhouse, and field conditions. Experiments included: 1) preliminary study of basic fertilizer sources to...
The reduction in mechanical load imparted on the body during spaceflight presents unique physiological challenges. One detrimental and seemingly unavoidable response to microgravity is rapid bone loss. This adaptation is hazardous not only to astronaut health, but to the success of long-duration exploration-class missions. Skeletal adaptation to spaceflight in astronauts...
After three-quarters of a century of introduction of 152 conifer and broadleaf species,
no promising candidate exotic was found for the Douglas-fir region. Growth curves
spanning 50 years or longer are figured for many species. Firs, pines, larches, spruces,
hemlocks, and cedars originating in northwestern North America had superior growth...
During summer 2007, perennial sea ice in the Beaufort Sea, Arctic Ocean, experienced an unprecedented amount of basal melt. It has previously been shown that this basal melt was linked to an increase in open-water fraction, increasing absorption of solar radiation into the ocean. GPS ice drifters, deployed around the...

The recent focus on transition from school to working
life has created a growing concern in Oregon about teachers
with elementary certification as their initial certification
who earn a special education certificate and teach students
with disabilities in secondary settings. Thus, the purpose
of this study was to investigate the...
Hydrocarbon solvents are widely used in the production of paints, adhesives, dyes, polymers, plastics, textiles, printing inks, agricultural products and pharmaceuticals. While the neuropathic potential of aliphatic solvents was shown in the 1970s, little is known about the neuropathic potential of aromatic solvents. The present study examines such solvents, 1,2-diethylbenzene...
Previous research has shown a gap between chemistry students' conceptual
and computational understandings of chemistry topics such as gas laws,
equilibrium, and reactions. This qualitative study examined the conceptual and
computational understandings of stoichiometry of college students enrolled in a
large lecture Introductory Chemistry course. Factors that might influence students'...
This study was designed to determine the common personal finance
competencies needed by graduating high school students in Oregon as
perceived by personal finance teachers from the subject matter areas
of business education, home economics, mathematics, and social studies
and the business community. Two other purposes were to (1) determine...
This investigation was designed to analyze change in critical .
thinking between students in laboratory-centered and lecture-demonstration-centered patterns of instruction in high school biology.
Twenty biology classes were randomly selected from the four
senior high schools in the Salt Lake City School District. Class enrollment
ranged from nine students in...
