Acid deposition and repeated biomass harvest have decreased
soil calcium (Ca) availability in many temperate forests worldwide, yet
existing methods for assessing available soil Ca do not fully characterize
soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it
has been hypothesized that the highly insoluble biomineral Ca...
OBJECTIVE: To evaluate the effectiveness of a 3-month treadmill desk intervention in eliciting changes in physical activity and sedentary behavior among overweight/obese office workers. METHODS: A randomized controlled trial was conducted among overweight/obese office workers (n=41; mean age = 40.1 ± 10.1 years) at a private workplace. Participants were randomly...
A radioactive particulate release experiment to produce a near-field ground deposition representative of small-scale venting from an underground nuclear test was conducted to gather data in support of treaty capability development activities. For this experiment, aCO₂‐driven “air cannon” was used to inject ¹⁴⁰La, a radioisotope of lanthanum with 1.7‐d half-life...
Four charges of S-inch paper roll plugs of Oregon maple were kiln-dried at various temperatures and humidities. The charge with the most desirable combination of short drying time and low degrade was dried to 12 per cent moisture content in lit hours, using a dry-bulb temperature of 160 degrees F...
BACKGROUND: In the prenatal period, women can have sustained contact with nurses and other clinicians, forming relationships that are likely to be health enhancing both for the woman and her unborn child. Yet first trimester care use in Oregon dropped noticeably over the past decade. In comparison with Washington State,...
OBJECTIVE: Pharmacokinetic interactions exist between combined
oral contraceptives and protease inhibitors (PI). However, such
information is lacking for progestin-only oral contraception. We
sought to define the steady-state pharmacokinetic interaction between
norethindrone (NET) and PI in HIV-infected women.
METHODS AND DESIGN: We conducted an open-label, prospective,
nonrandomized trial to characterize the...
Checking was influenced b drying conditions. This influence was greatest before average moisture content reached 20 per cent, but tension in surface layers caused checking even below this point.
Neither high initial dry-bulb temperature nor initial conditions of high equilibrium moisture content were conducive to checking.
High temperature and high...
In this thesis I explore the ways in which twenty-first century Americans have access
to Geoffrey Chaucer and his works. I look at issues surrounding Chaucer within the
canon debate, high school history and literature textbooks, and Chaucer in popular
culture, such as in movies like A Knight's Tale. I...
My thesis, entitled “The Clerk’s Tale: Literal Monstrosities and Allegorical Problems,” argues that Chaucer’s Clerk is engaging both sides of a binary system. The Clerk has situated himself in a precarious position between two major schools of thought in the medieval culture, Franciscan and Dominican; the former promotes the will...
The Pigeon Guillemot (Cepphus columba) is now the only species of marine bird in Prince William Sound (PWS), Alaska that is listed as "not recovering" on the Exxon Valdez Oil Spill (EVOS) Trustee Council's Injured Resources List and has shown no sign of population recovery. During the 20 years since...
In this memoir, by alumnus and Zoology Department instructor William J. Gilstrap, the author details various aspects of his life, including: childhood in Missouri, student experience at Oregon Agricultural College (OAC) in the 1890s, and his medical practice in various Oregon locales. Gilstrap also describes in this narrative the origins...
Thomas Stearns Eliot’s 1922 modernist poem The Waste Land presents itself as an alternative to the decaying society Eliot found himself inhabiting. It begins as a personal means of pulling together one’s fragmented consciousness, but in doing so Eliot manages to present a solution to a world of selfishness—looking beyond...
Gothic literary works are characterized as such by their ability to represent and evoke terror. The form this representation takes is varied; often terror originates in the atmospheric effects of settings, in the appearance of mysterious, supposedly supernatural phenomena, and, perhaps most significantly, in the behavior of villainous characters. Shakespearean...
Over recent decades, the marine ecosystems of Prince William Sound (PWS), Alaska have experienced the concurrent effects of a major anthropogenic disturbance, the 1989 Exxon Valdez oil spill (EVOS), and a dynamic atmospheric-oceanic environment. Studies of top marine consumers can provide insights into processes of ecosystem change. Using data collected...
The essays in this collection do not cluster about a specific theme, nor do they present a single unified interpretative approach to issues in the history of American foreign policy. Above all, William Appleman Williams is a teacher. And good teachers are disappointed with conformity. No one would ever come...
The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...
Dedicated to the preservation and promotion of many of the nation’s most threatened and endangered species, the W.L. Finley National Wildlife Refuge is highly invested in the management of some of the last remaining upland prairies once prevalent throughout Oregon's Willamette Valley. More than a century of land fragmentation, fire...
The Modern era, roughly the time between 1860-1930, brought about a significant restructuring of artistic mediums. From the canvas to the page, artists of the twentieth century turned towards collaboration as a means by which they could reconfigure their works. Painters, writers, and dancers, borrowed aesthetic techniques from one another...
The study of the question of why Shakespeare's Hamlet delays killing
Claudius in revenge for his father's murder is examined in light of the major
critical theories from neo-classical to modern scholarship. An expanded
treatment of the works of Fredson Bowers, Eleanor Prosser, Bertram Joseph,
and Roland Frye, is provided...
Atrazine, atratone and ametryne are asymmetric s-triazine
herbicides used pre- and post-emergence on many crops. Under
conditions unfavorable for microbial activity, these compounds
may persist in the soil for long periods of time.
This study was conducted to determine the influence of the
soil microflora upon atrazine, atratone and ametryne...
Three experiments whose objectives were to investigate cover
crop kill by winter freeze, weed suppression by 'Micah' barley and
other spring cereals, and allelopathic potential of cereal covers
were conducted at the Vegetable Research Farm and in the greenhouse
and growth chamber facilities at OSU in 1989/90. Kill by winter...

Potato (Solanum tuberosum L.) is one of the most productive and nutritious food crops. Due to its adaptability to cool climates, production in Sri Lanka has been restricted to erosion-prone highlands. Vast potential exists for expansion of potato cultivation in the lowlands while production areas in the highlands are limited...
Detailed bathymetric survey data were collected along the Peruvian
continental margin and were compiled by the author and other
investigators to construct a new bathymetric map for the area between
6° to 18°S latitude. Based on this map and individual bathymetric
profiles, the continental shelf topography is essentially flat. Four...
The pigeon guillemot (Cepphus columba) population in Prince William Sound has failed to recover from declines that occurred both before and after the Exxon Valdez Oil Spill (EVOS). Post-spill studies of pigeon guillemot breeding biology have identified three potential factors limiting recovery: (1) predation on eggs and nestlings; (2) declines...
Breeding habitat of Harlequin ducks (Histrionicus
histrionicus) was studied in eastern Prince William Sound,
Alaska, during 1991 - 1993. Streams in Prince William
Sound were surveyed for Harlequin ducks and monitored with

breeding streams were compared to those of 24 streams not
used...
Detailed surveys of several segments of the Peru Trench show
that the region between 6° to 10⁰ S is an area of recent deformation.
Seismic reflection records across the axis of the trench show faulting,
uplift, and tilting of the sedimentary fill and the acoustic basement.
Uplift of the acoustic...
During his lifetime C. S. Lewis chose to speak to Christians in plain and simple language that they could understand. Lewis taught and defended truths that he felt were discernible through reason. Morality, free will, and the divinity of Jesus Christ were fundamental to his core beliefs and teachings. His...
The phenomenon of phantom limb pain has been well documented for centuries, but little clinical work has been done to alleviate it. Physician and neuroscientist Vilayanur S. Ramachandran began researching this condition nearly two decades ago, and has discovered a promising alternative treatment: mirror-box therapy. This therapy is not yet...
Within The Lamplighter, a novel written in 1854, Maria
Susanna Cummins defines a version of the sentimental novel
that significantly differs from the prescriptive analysis
male critics have offered for the genre. This thesis
argues that feminist theory and recent rhetorical theory
have caused a critical paradigm shift that has...
