The major purpose of this study was to examine relationships
among biographical characteristics, psychological characteristics,
motives for returning to school, and the need for student support
services among Reentry Women.
Primary objectives were to:
(1) examine biographical and psychological characteristics of
Reentry Women to determine if significant relationships
existed among...
Thermal decomposition of several di-p-toluenesulfonylhydrazones
was studied. It was found that the carbene decomposition
of tetramethyl-1,3-cyclobutanedione, di-p-toluenesulfonylhydrazone
gave two products resulting from
rearrangement. One was identified as 2,5-dimethyl-1,3,4-hexatriene. A tentative structure for the second was
proposed. During the course of the study, a more convenient
procedure for thermal decompositions was...
The overall objective of this research project was to evaluate
the metabolism of benzo(a)pyrene (BaP) by the European flat oyster
(Ostrea edulis)-bacteria system. Individual oysters exist in nature
as "systems" with commensal microorganisms and should be recognized
as such when the metabolism of a specific environmental contaminant
is being studied....
An increasing number of children care for
themselves (self-care) while their parents are employed
outside the home. A literature review suggested a
connection between child care concerns and employed
parents' increased stress, role overload, and lower
productivity. This study evaluated the impact of an
educational training program for families with...
Oregon Department of Fish and Wildlife trout broodstocks from Alsea, Cole Rivers, Klamath, Leaburg, Oak Springs, Roaring River and Willamette Fish Hatcheries were examined for the presence of myxosporidans. Wild fish collected from waters above these hatcheries were also examined. Seven species of myxosporidans were observed in the hatchery broodfish:...
Over the past 42 years clay smoking pipes have been excavated from two U.S. army posts, Fort Hoskins (35BE15) and Fort Yamhill (35PO75) and curated at Oregon State University. These two forts were established in Western Oregon in 1856 and by 1866 both had been decommissioned. Numerous theses have focused...
Distribution and characteristics of soils were determined across
a series of six coastal terraces in Curry Co., Oregon.
Classification of soils and interrelationships of properties were
determined. Soil-landscape relationships were examined and soil
profile development related to relative ages of terraces. Ten pedons
were sampled from five terraces of Pleistocene...
A structural model of the Pacific halibut fishery is developed. Hypothesis tests
are developed within the framework of the "new empirical industry organization" for
the exertion of market power by Pacific halibut processors in both the exvessel market
and the wholesale market. The relationship of market power exertion and IPHC's...
Seasonal polyphenism demonstrates an organism's ability to respond to predictable environmental variation with alternative phenotypes, each presumably better suited to its respective environment. However, the molecular mechanisms linking environmental variation to alternative phenotypes via shifts in development remain relatively unknown. Here we investigate temporal gene expression variation in the seasonally...
This is the first data report of a program designed to study physical
processes in Oregon shelf waters by means of moored instrument arrays.
Various statistics and plots of smoothed data are presented for time
series of current velocity and of temperature. Data were collected in
July, August, September, and...
Next-generation DNA sequencing (NGS) approaches are rapidly surpassing Sanger sequencing for characterizing the diversity of
natural microbial communities. Despite this rapid transition, few comparisons exist between Sanger sequences and the generally
much shorter reads of NGS. Operational taxonomic units (OTUs) derived from full-length (Sanger sequencing) and pyrotag (454
sequencing of...
The Conference Program for IIFET, held July 10-14 in Corvallis, Oregon. Program lists the sessions by date and time and includes the session titles, speakers and paper titles.
Focus on Forestry is published by Oregon State University College of Forestry. Our goal is to keep Forestry alumni, friends, faculty, staff, and students informed about the College of Forestry and its many activities and programs.
A significant proportion of the population of the United States suffers from chronic pain, a category of disease that is not yet well understood by healthcare professionals. A majority of this group is made up of women; individuals who often have to convince healthcare professionals that their symptoms are real...
The War Production Board issued limitation order 85 in April 1942 in order to conserve fabric and manpower needed for the war effort. The L-85 order froze the silhouette so no major style changes in women's wear would occur during the war. It is clear that on the one hand...
This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....

Reversion of resistance to the organotin (OT) acaricide
cyhexatin was documented for the twospotted spider mite,
Tetranychus urticae (Koch), by laboratory isolation of a
field resistant colony. After 22 generations of no
selection the colony reverted back to susceptible.
Studies were conducted in 1985 and 1986 on susceptible
and resistant...
A compartmental modeling approach is presented to route nitrate retention along a cascade of stream reach sections. A process transfer function is used for transient storage equations with first-order reaction terms to represent nitrate uptake in the free stream and denitrification in the storage regions. In the context of a...
Site 35JA42 represents the first protohistoric village
complex excavated in Southwest Oregon. Analyses of animal
bones recovered from the site offer the first significant
insights into human subsistence behaviors in this region.
Although the faunal assemblage is extremely fragmented,
detailed zooarchaeological analysis indicates that deer were
the primary meat resource...
To study the combined effects of seedling quality and fertilization at the time of planting, three experiments were established in western Oregon during the winter of 2000. The first experiment investigated the effect of preplanting rootvolume and fertilization rate on the field performance of 1+1 Douglas-fir seedlings during two growing...

In 1967, Doi et al. proposed the hypothesis that 'yellows type
diseases' are caused by mycoplasma. Since then more than 60
yellows diseases have been associated with mycoplasma-like bodies
(MLB) (Maramorosch, 1973). The majority of these associations are
based upon electron microscopic observations of mycoplasma-like
bodies in situ. However, little...
Through this dissertation, the quality of freely available physical activity promotion web articles that lay adults would likely locate online was critically appraised and theoretically analyzed. Three broad categories were considered. They were 1) message consistency with national health guidelines for physical activity; 2) suitability for health-related communication; and 3)...

The Champoeg townsite first developed due to its ideal settlement and trade location within the Willamette Valley, becoming the ‘legal birthplace of Oregon’ in 1843. However, by 1860 Champoeg’s significance had begun to decline, and in December of 1861 a devastating flood wiped out the townsite. Archaeological excavations took place...
Persistent and uncontrolled inflammation is the root cause of various debilitating diseases. Given that interleukin-1 receptor–associated kinase 4 (IRAK4) is a critical modulator of inflammation, inhibition of its activity with selective drug molecules (IRAK4 inhibitors) represents a promising therapeutic strategy for inflammatory disorders. To exploit the full potential of this...
A gene's duplication relaxes selection. Loss of duplicate, low-function DNA (fractionation) sometimes follows, mostly by deletion in plants, but mostly via the pseudogene pathway in fish and other clades with smaller population sizes. Subfunctionalization — the founding term of the Xfunctionalization lexicon — while not the general cause of differences...
Haiti is far from achieving the UN goal of sanitation access for all; 20% Haitians have no sanitation access, and less than 0.1% of urban excreta is safely managed. Container-Based Sanitation (CBS) may be a key tool for achieving equitable sanitation coverage in Haiti’s cities. CBS is a sanitation strategy...
