Species associations of fifteen major commercial groundfish species in the
northeastern Pacific ocean and their spatial and temporal characteristics were studied
using Oregon bottom trawl logbook data, 1987 to 1993. Screening procedures were used
to remove questionable data from the original logbook files, which resulted in the
exclusion of information...
This was a study designed to determine the occurrence of recovery
from radiation damage in Taricha granulosa. Irradiation with either
gamma or x-ray sources in the range of 96-10,000 rads was given. (The
mean or median survival times were determined.) Doses were fractionated
and the survival times for the same...
Effects of light intensity, exposure to desiccation, reduced
salinity, and thermal elevation on the functional and structural characteristics
of marine benthic diatom communities were investigated
in a laboratory model ecosystem and a respirometer chamber.
Measurements of biomass (dry weight and ash-free dry weight)
and chlorophyll a were made for each...
The thesis area includes 44 square miles of the Centennial
Range in Beaverhead County, Montana, and Clark County, Idaho.
The rocks exposed in the area range in age from Precambrian
to Recent and have been divided into 23 mapped units. Pre-Belt
metamorphic basement rocks are overlain unconformably by 3,433
feet...
Marine fish are subject to direct and indirect oceanographic variations operating at short and long time scales. In this study feeding habits and long-term growth condition of several groundfish species of the Pacific Northwest are examined to understand the relationship between variations in the fish's biological and life history components...
Leptarctia californiae (Walker) was studied on clear and semi-forested southern slopes in the Coast Range Mountains of Benton County, Oregon. The spring of 1965 had an unusually long warm period (21 days) resulting in adult emergence approximately 25 days earlier than in the cooler spring of 1966. Peak flight activity...
Malonaldehyde, a three carbon dialdehyde, is one of the numerous
carbonyl compounds associated with oxidative deterioration of
food lipids. It is assumed to be formed as a product of lipid autoxidation
occurring according to the generally accepted free radical
mechanism. This compound is of great interest because of its potential...
Flat, laminar, premixed hydrocarbon-air flames were stabilized
on a porous-plate burner. In addition to temperature profiles,
concentration profiles were measured for methane, ethane, ethylene,
propane, acetylene, propylene, carbon monoxide, carbon dioxide and
oxides of nitrogen. Dead space thickness, luminous flame zone
thickness and hydrocarbon disappearance point responses were also
monitored....
This dissertation focuses on the life of Dixy Lee Ray as it examines important developments in marine biology and biological oceanography during the mid twentieth century. In addition, Ray's key involvement in the public understanding of science movement of the 1950s and 1960s provides a larger social and cultural context...
Recently, switched-current circuits have received great
attention because they offer potentially better performance in terms
of speed, low voltage power supplies, and accuracy in mixed-mode
analog-digital signal processing. In this thesis, the distortion
characteristics, DC offset and AC gain errors induced by the threshold
voltage, channel width, channel length, and...
NAND flash based solid state drives (SSDs) require out-of-place updating due to the characteristics of flash memories. In addition, due to the mismatched granularity between read/write and erase operations, a cleaning policy involving garbage collection and wear leveling has to perform data migration incurring high overhead. Another challenge is that...
This research explores the consequences and effects for men
enrolled in introductory Women Studies courses at Oregon State
University. Men are enrolling in the feminist classroom in larger
numbers due to institutional changes allowing Women Studies to
provide credit for baccalaureate core curriculum. The intention of
this study is to...
Since its introduction in the early 1990s, the quick growth of the World Wide Web
(WWW) traffic raises the question of whether past Local Area Network (LAN) packet
traces still reflect the current situation or whether they have become obsolete. For this
thesis, several LAN packet traces were obtained by...
The purpose of this study is to critically analyze whether India’s National Population Policy of 2000 represents a paradigm shift in terms of how the nation-state conceptualizes and address population growth through formal population policy. Analyzed through transnational feminist theory, this study employed political discourse analysis as the research method....
This thesis focuses on performances of masculinity by British Royal Flying Corps (RFC) airmen in the charged landscape of the First World War prisoner of war (POW) camp. I examine how captive airmen coped with imprisonment by reasserting the familiar homosocial communities of pre-capture squadron life, particularly through practices associated...
Dynamic multithreaded processors attempt to increase the performance of a single
sequential program by dynamically extracting threads from sources such as loop
iterations. The scheduling of instructions in such a processor plays a vital role in the
amount of thread level parallelism that can be extracted and thus the overall...
The AE32000 processor core, developed by Advanced Digital Chips Inc., Korea, is used primarily in the embedded processing environment. The AE32000 simulator models this embedded processor core having high code density. An enhanced simulator was developed to study the performance of the present Instruction Set Architecture after comparison with the...
