Currently, wax printing is limited to materials that can be processed by a wax printer. Wax transfer printing is a method that allows previously unusable materials to be patterned with wax via an intermediate template. Millipore cellulose, a material too thick to be processed by a wax printer, was patterned...
There are at least fifteen types of upper extremity tendon transfer procedures for combined peripheral nerve injuries that involve re-routing a single donor muscle to multiple recipient tendons. As a result, force and movement across finger joints become coupled, resulting in limited grasping abilities. Quantification and modeling of the donor...
Straw wattles are common erosion control devices used to trap sediment. This
thesis studies the relationship of straw wattles on slope stability through a case study
demonstrating their use on steep slopes (1.5H:1V) for the US20 highway realignment
project. Several surficial slope failures have occurred on these fill slopes, often...
Over-winter growth of juvenile salmonids may be linked to ocean survival and thus species persistence. Diet, growth, and prey available to juvenile coho, Oncorhynchus kisutch, were examined from December 2004 to April 2005 in four tributaries of the West Fork Smith River (WFSR), Oregon. Juvenile coho growth rate and condition...
Field experiments were conducted with cauliflower (Brassica oleracea var.
botrytis cv. Snowball Y ) to determine crop development, yield, quality and
maturity response to various seasonal water levels, and to specific water stress
timing in relation to curd initiation. The effects of nitrogen rate, timing, and
source and the application...
Pacific flatheaded borer (PFB), Chrysobothris mali Horn (Coleoptera: Buprestidae), has recently become a serious pest in newly planted European hazelnut, Corylus avellana L. (Betulaceae) in Oregon. Larvae feeding on the inner bark can lead to girdling, loss of transpiration, and ultimately can cause dieback or death of the tree. Although...
Educational institutions are exposed to a continuously changing environment. As in business, they experiment with their methods and techniques to improve their outputs. Performance assessment, both in education and business is a gray science. It is not just a question of evaluating performance. Performance is comprised of a number of...
This work focuses on the generation and collection of four specific
radioxenon isotopes; xenon-131m, xenon-133m, xenon-133 and xenon-135. These

possible differences between teacher expectancy and child performance
at the first grade level. The Beaverton Public Schools participated
in the study with their first grade children and teachers, using an
examination administered to a random sampling of children and...
Community colleges have long been thought of as the "people's
college." For some thirty years, Oregonians have looked to their 16 community
colleges as the less expensive, more accessible route to a college education.
Oregon's community colleges have traditionally had the broad mission of
providing comprehensive educational opportunities to all...
Surface transient storage (STS) in stream ecosystems serve an important function in retaining nutrients and refugia for aquatic communities. Unfortunately, they can retain contaminants as well. Therefore, it is of importance to determine the residence time distribution (RTD). A RTD of a particular STS zone encompasses the time it takes...
Nitrogen deficiency during the winter where winter wheat
(Triticum aestivum L.) follows wheat and large amounts of straw
have been plowed down has been a factor limiting yield in the
Willamette Valley of western Oregon. Field experiments were
established to determine if an application of N on the stubble or...
Inner-shelf circulation and mechanisms of across-shelf transport of water masses were examined using seven years of observations collected by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) program, a long-term monitoring effort along the central Oregon coast. Since 1998, moored velocity and hydrographic measurements have been obtained during the...
Why are fisheries policies so hard to reform? While there are many examples of successful policy reform in the sector, these tend to be restricted to a few countries or individual fisheries. There remains significant scope for further reform to address pressing economic, environmental and social issues in the sector....
This study characterized the nature and dynamics of interference in mixed red alder
(Alnus rubra Bong.)/Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) stands in the Pacific Northwest, USA. Long-term spatial and tree measurements from the Cascade Head (CH) and H.J. Andrews (HJA) Experimental Forests in western Oregon and Delezene Creek (DC), Washington...
With the advent of next generation reactor systems and new fuel designs, the U.S. Department of Energy (DOE) has identified the need for the resumption of transient testing of nuclear fuels. The DOE has decided that the Transient Reactor Test Facility (TREAT) at Idaho National Laboratory (INL) is best suited...
Equal value gray scales are frequently employed by cartographers to choose gray tone area
symbols. Several researchers have tried to quantify perceived gray tone as a function of percent area inked or
reflectance but results have varied. The influence of pattern and texture on gray tone perception is considered
a...
This paper presents an exposition of the stochastic models
for the Brownian motion. The results of Einstein and Wiener are
presented, together with the Uhlenbeck-Ornstein process which
gives a more realistic model of the Brownian motion of a particle.
Finally, applying a one-one transformation on the forward
Kolmogorov equation we...
The research revolves around membrane-assisted electrolysis to recover caustic soda from alkali processing. This research began with the lab having no experience in electrochemistry and thus conducting initial experiments to begin to understand electrochemical systems. The lab then looked at both gas production and anodic fouling behavior. The lab then...

An ontological categorization, the fundamental research contribution of this work, is created to support both aims of the overall methodology. Providing designers with a customer...
Restrictions on flows of foreign direct investment (FDI) in most sectors of OECD countries have been significantly reduced in recent years. In contrast, FDI in the fish harvesting sectors of OECD countries is still heavily restricted through a range of measures including outright bans on FDI, maximum allowable levels of...
This thesis situates a discussion of Thoreau's later natural history essays in the context of the author's other writings. Beginning with an examination of the writings of Thoreau's friend and mentor Ralph Waldo Emerson, this paper examines Thoreau's relation to and departure from Emerson's understanding of time, place, and pattern...
A Willamette Valley farm cooperative was interested
in evaluating locations for their canning facilities based on
the criterion of minimizing aggregate distance to their contract
farms. This location problem presented an excellent opportunity
for a geographic application project as it was characterized by
one, a spatial distribution of farms and...
Cost recovery has been a fundamental feature of the management of Australia's Commonwealth fisheries since the mid-1980s. The general philosophy of the current Commonwealth cost recovery model, introduced in 1994, is that the beneficiaries of government services should meet the costs of those services in accordance with the concept of...
This historical survey sweeps across a thousand years, divided into five very unequal stages. Over most of the stages property in tide-water fisheries was lost. Fishers lost control of the fishstock and of the markets they served. Governments responded with fishing regulations, which have served as a basis for regaining...
This thesis argues that the first two novels of Cormac McCarthy’s The Border Trilogy mark a sharp turn from the antihumanism of his earlier ‘Southern’ novels to a more affective exploration of posthumanist subjectivity within a world dominated by social discourse and metanarratives. In my examination of All the Pretty...
The Hanford Nuclear Reservation drew public ire during the 1980s and 1990s when activist groups forced the declassification of 19,000 documents and discovered proof of accidental and intentional releases of radioactive materials into the environment. These releases had been kept from the public. Although many locals had for decades wondered...
Variability in the terrigenous (land-derived) fraction of marine sediments,
including pollen and rock fragments, reflects the effects of regional climate change on
continentally derived runoff, ice extent, vegetation and ocean circulation. The transport of
this continental material to the seafloor must be understood in order to interpret the
terrigenous sediment...
Determining age in crustaceans is inherently imprecise because they molt
periodically and do not retain hard structures throughout their lifespan. Morphological
measurements, such as carapace length, are often used to estimate age because
methods for direct ageing do not exist. However, variability in individual growth rate
and molt frequency can...
The major objectives of this study were to ascertain if certain ethnic and racial groups of first-year Oregon State University students are without access to online admission materials, and to determine what students' point of view are about computer access or applying to Oregon State University online.
