Nine west-northwest-trending faults on the continental margin of
Oregon and Washington, between 43° 05'N and 470 20'N latitude, have been
mapped using seismic reflection, sidescan sonar, submersibles, and swath
bathymetry. Five of these oblique faults are found on both the Juan de Fuca
and North American plates, and offset abyssal...
Interspecific predation and cannibalism and associated rates of oviposition were
assessed for adult female Metaseiulus occidentalis (Nesbitt) and Typhlodromus pyri
Scheuten when provided non-limiting amounts of either eggs, larvae, protonymphs, or
deutonymphs. Tests with all four stages of phytoseiids and larvae of Tetranychus urticae
Koch were carried out at 25°C....
Six experiments were carried out with Single Comb White Leghorn laying chickens to
assess the effect of feeding a source of direct-fed microbials (Lactobacillus; Lacto) and its
carrier [condensed cane molasses solubles (CCMS)] on the retentions of fat, nitrogen and
several minerals; on the status of the pH of the...
A synthetic approach toward the two major fragments of cathedulin K-19,
euonyminol (4) and dimethyl cathate (69), was investigated. Synthesis of
dimethyl cathate was accomplished in 3 steps starting from 73. Efforts directed
towards the synthesis of euonyminol, a highly oxygenated dihydroagarofuran
sesquiterpene, was advanced to a stage in which...
Bidirectional reflectance is a fundamental property
used for the analysis of radiative heat transfer. It is a
form of reflectivity in which the spectral and directional
dependencies of both the beam incident on a surface and the
beam reflected from the surface are specified.
A new system has been designed...
More than 30,000 potential Superfund sites have been identified. Heavy metals are contaminants at many of these Superfund sites. The average cost of cleanup a single-typical Superfund site currently stands at $20 million, and it is expected that the cost may escalate to $50 million within the next decade. Problems...
An oscillating plasma glow discharge detector for gas
chromatography is used to obtain fingerprint information
about an analyte by combining both the average cell
current and oscillation frequency signals. Five homologs
each of the n-alkanes, 1-alkenes, 1-alkynes, 2-ketones and
aldehydes are studied. Although triplicate determinations
had some scatter due to...
The purpose of this study was to determine if the inferences derived from
the Kingore Observation Inventory as a screening device are sufficiently valid for
the identification of potentially gifted youngsters. Differences in predicting the
WISC-III Full Scale IQ scores and/or percentile ranks using the KOI were
assessed.
The value...
The purpose of this study was to describe and explain significant mentor/protege
relationships in professional ministry education. Through an exploratory, naturalistic inquiry,
the mentoring phenomenon was studied inductively, culminating in a descriptive theory that
illuminated the variables and their interrelationships on the ministerial campus.
The multiple case study design accommodated...
The probing behavior and feeding activity of green peach aphid, Myzus persicae
Sulzer, on Bacillus thuringiensis ssp. tenebrionis- transgenic potatoes, insecticide
treated potatoes, and host plants with different preference were electronically
monitored. I found that first, transgenic potatoes had no effect on green peach aphid
probing suggesting that transmission of...
The study examined dimensions of the family context associated
with variations in parent involvement and parent perceptions of children's
school achievement using data from 1,085 male and 2,239 female
respondents with a child between the ages of 5 and 18 years collected in the
1987-88 National Survey of Families and...
The thesis analyzes the demographic, attitudinal and
behavioral characteristics of animal rights activists,
placing them in the context of resource policy. It is
argued that the animal rights movement combined the
Victorian critique of empiricism with a reaction to
modernity that was characteristic of other contemporary mass
movements. Animal rights...
This paper presents two applications of empirical microeconomics
based on choice theoretic optimization principles. The first topic
explores the determinants of subsistence time allocation in a utility
theoretic model of household production. The second topic examines firm
pricing behavior in a deregulated, but concentrated industry setting.
The first part of...
The groundfish trawl fishery operating off the coasts of Oregon
and Washington 1985-1987 caught six major assemblages of species
which could be treated as units in developing mixed-species
management plans. Eighty-one percent of the tows observed on
commercial vessels were consistently placed in one of the assemblage
designations using three...
Families of remarriage constitute a growing number of
American families. The spiraling divorce rate of the 1970s
was accompanied by a concomitant increase in the number of
remarriages. Forty percent of American families today
contain at least one spouse that has been previously
married, thus studying relationships within families of...
Quality Capability Self-diagnosis is a convenient and
economical way to assess the performance of an operating
quality system, as well as a basis for initiating necessary
corrective actions essential to quality improvement and
preparation for certification. This paper describes the
research leading to the development of a cost-effective and
systematic...
Stochastic analysis procedures have been recently applied to analyze nonlinear
dynamical systems. In this study, nonlinear responses, stochastic and/or chaotic, are
examined and interpreted from a probabilistic perspective. A multi-point-moored
ocean structural system under regular and irregular wave excitations is analytically
examined via a generalized stochastic Melnikov function and Markov...
When large disturbances occur in interconnected power systems, there exists the danger
that the power system states may leave an associated region of stability, if timely corrective action
is not taken. Open-loop remedial control actions such as field-forcing, line-tripping, switching of
series-capacitors, energizing braking resistors, etc., are helpful in reducing...
Two epidemiological studies, designed to expand our knowledge of morbidity and
mortality indicators concerning malaria and Bacillus Calmette-Guerin vaccination in the
Hospital Albert Schweitzer health district located in Central Haiti's Artibonite Valley, are
presented. The hospital serves a rural population of 190,000 in its 610 square mile
district. A large...
Studies investigating the effects of feeding diets
containing the yeast, Saccharomyces cerevisiae var.
boulardii (SCB), and a yeast culture (YC) containing S.
cerevisiae were conducted in market turkeys and Medium White
turkey breeder hens.
Increased utilization of dietary gross energy, N, Ca,
P, B, K, Mg, and Mn were observed...
Accurate determinations of body composition, fat mass (FM) and fat-free
mass (FFM) are of interest to scientists as well as many individuals
who serve as health and fitness practitioners. Currently, researchers and
practitioners use a variety of indirect methods to determine body
composition. Traditional methods of estimating percent body fat...
This study examined the teaching experiences of six elementary student
interns from Oregon State University, Corvallis, OR during fall and winter quarters,
1991. The primary intent of the study was to examine critically the roles and
effects of mind styles as applied in actual classroom instruction and learning, in
terms...
The Delton Silent Reading Test, Forms A and B, was
developed as an alternate test for the Schonell Silent Reading
Test which is currently used for screening the reading
comprehension of special students. The aim of the Delton
Silent Reading Test is to achieve greater consistency in mid-year
and mid-program...
This study investigated the relative effectiveness of
three instructional strategies on the learning of an overarm
throw among preadolescent females. Subjects were randomly
assigned to one of the following instructional strategies:
a correct model supplemented with verbal cues, a learning
model supplemented with verbal cues, and verbal cues only.
The...
Many divorcing persons turn to treatment programs hoping for assistance in
managing the process of divorce. Treatment programs include individual as well as
group process models. One of the goals of most group process programs is to
generate peer support which in turn is hoped to facilitate the process of...
The purpose of this case study was to explore the
perceptions of school district administrators and members
of the community about the influence of school-based
activities had on voter behavior. The case study focused
on a school district in the Willamette Valley of Oregon.
Interviews were held with the school...
