This thesis discusses the African American authors Richard Wright and James Baldwin, and their views regarding how literature should be written. These views are examined as laid out in a selection of each author‟s essays, as well as through an analysis of the characters Bigger Thomas and Rufus Scott in...
Arctic sea ice concentration and volume have declined due to greenhouse gas radiative forcing and an overall positive climate feedback. At the same time, there have been noteworthy weather and climate circulation anomalies both within the Arctic and extending through the midlatitudes and even into the tropics, leading some studies...
This study was conducted to determine if there were

Product development efforts are extremely important to a company's success in today's global competitive business environment. Yet, these highly consequential efforts are terribly nebulous to a point that past experiences are inherently underutilized. This thesis demonstrates a methodology to quantify past product development efforts in an attempt to better utilize...
Sand dunes are used as indicators of wind
power potential and examples are presented of their application
as a prospecting technique at four study sites in

This thesis presents methods for treating annihilation photon pairs in deterministic pulse height distribution (PHD) simulations. The methods are applied in PHD simulations for monoenergtic sources of 1.6 and 2.6 MeV photons incident on 5 and 10 cm 1-D slabs of germanium, sodium iodide, and lead and the results are...
Current frameworks for analyzing forest carbon offset projects in disturbance-prone western forests often fail to address the dynamic nature of carbon pathways through time. They do not account for the probability of loss due to wildfire, which can influence the prediction of carbon storage at the end of a planning...
The work described herein details the synthesis and application of
biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents

from inexpensive commercially...
The ability of the resin to deform plastically can be an

Twenty- six mountain goats (Oreamnos americanus), located between the Lostine River drainage and the East Fork Wallowa River drainage of the Wallowa Mountains, were monitored from June 1972 through June 1973.

Diffusion in a fissured medium with absorption or partial saturation effects leads to a pseudoparabolic equation nonlinear in both the enthalpy and the permeability. The corresponding initial-boundary value problem is shown to have a solution in various Sobolev-Besov spaces, and sufficient conditions are given for the problem to be well-posed.

An industry panel tasting of wine from the 1987 Pinot noir maturity trials (see previous article by Watson et al this issue) was conducted at OSU in April, 1988. Thirteen winemakers participated in the half-day tasting which involved both the description of the aroma and flavor of the wines and...
Calculation of vector winds from spaceborne fan-beam scatterometers requires that backscatter measurements from different antennas be relatively calibrated to high accuracy. A method is developed to perform postlaunch antenna calibration using global mean ocean backscatter measurements in conjunction with estimates of the statistical distribution of near-surface wind velocity and the...

Motivation: The goal of any parentage analysis is to identify as many parent-offspring relationships as possible, while minimizing incorrect assignments. Existing methods can achieve these ends, but require additional information in the form of demographic data, thousands of markers, and/or estimates of genotyping error rates.

Water vapor transport in the vicinity of imbibing saline solutions was investigated in two-dimensional (2-D) chambers using a light transmission technique. Concentrated NaNO3 solutions (brines) were applied as point sources to the surface of homogenous packs of prewetted silica sand for four different sand grades. The same solutions were applied...
Retrievals of cloud properties from satellite imagery often invoke the assumption that the fields of view are overcast when cloud-contaminated, even though a significant fraction are only partially cloud-covered. The overcast assumption leads to biases in the retrieved cloud properties: cloud amounts and droplet effective radii are typically overestimated, while...
Ambiguity in wind direction has long been an impediment to applications of wind observations from the Seasat scatterometer (SASS). Three months of unambiguous global SASS vector winds (7 July-10 October 1978) have recently become available from the Goddard Space Flight Center(GSFC) Laboratory for Atmospheric Sciences. The directional ambiguities were removed...
A high-resolution upper-ocean survey of a cyclonic jet meander and an adjacent cyclonic eddy in the California Current region near 38°N, 126°W was conducted as part of the summer of 1993 Eastern Boundary Currents program.

Acetylene is a slow-binding inhibitor of the Ni- and Fe-containing dimeric hydrogenase isolated
from Azotobacter vinelandii. Acetylene was released from hydrogenase during the recovery from inhibition.
This indicates that no transformation of acetylene to another compound occurred as a result of the interaction
with hydrogenase. However, the release of C2H2...
Bench scale column studies were used to examine the partitioning of microorganisms between groundwater

Six 40-year-old red alders (Alnus rubra Bong.) were harvested from a mixed stand of A. rubra and big-leaf maple (Acer macrophyllum Pursh) in the Oregon Coast Range to evaluate variation in their wood characteristics at two heights. Because the trees had a slight lean (4 to 14°), we sampled along...
In order to analyze the variation in wood properties within and between trees of an underutilized tree species, we sampled six Oregon white oak (Quercus garryana Dougl.) trees from an 80-year-old mixed stand of Q. garryana and Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) in the Coast Range of Western Oregon, USA....
Understanding the association between growth rate and wood properties is of practical importance to maximizing and sustaining wood and fiber production.

Of all Pacific salmonids, Chinook salmon Oncorhynchus tshawytscha display the greatest variability in return times to freshwater.
