An Analysis Of The Ph Tolerance And Substrate Preference Of Isolated Skeletal Muscle Mitochondria From Bufo Marinus And Rana Catesbeiana, Jeffrey Mark Duerr

Dissertations and Theses

The concept of maximal oxygen consumption (VO₂ max) implies that there is a limit to the amount of oxygen that can be consumed by an organism in a given time. Many attempts have been made to delineate exactly what factor or factors are limiting to VO₂ max. Current models focus on the steps over which oxygen must traverse in order to get from the ambient air to the mitochondria. However, no model has addressed the issue of whether or not carbon dioxide flux may impose a limit to VO₂ max. Impedance of carbon dioxide flux may have …

Chinese Women As Cultural Participants And Symbols In Nineteenth Century America, Tina Michele Landroche

Dissertations and Theses

Chinese female immigrants were active cultural contributors and participants in nineteenth century America, yet Americans often simplified their roles into crude stereotypes and media symbols. The early western accounts concerning females in China created the fundamental images that were the basis of the later stereotypes of women immigrants. The fact that a majority of the period's Chinese female immigrants became prostitutes fueled anti-Chinese feelings.

This thesis investigates the general existence of Chinese prostitutes in nineteenth century America and how they were portrayed in the media. American attitudes toward white women and their images of Chinese women created the stereotype of …

Interpretation Of The Thermal Behavior Of Groundwater In An Alluvial Terrace: Bonneville Dam, Columbia Gorge, Oregon, Richard Stephen Malin

Dissertations and Theses

Groundwater temperature data, collected at an alluvial terrace located on the Oregon shore of the Columbia River downstream from Bonneville Darn, was analyzed in order to characterize and formulate a conceptual model of the thermal data for the groundwater system in the terrace. There is concern that an unlined entrance channel for a new navigation lock, to be located down the middle of the terrace, will widen the range of temperatures in the fish hatchery-groundwater supply. The analysis of temperature behavior in the terrace supports the hydraulic observations derived from analysis of pump test data, but with greater definition of …

Field-Equation Approximations And The Dynamics Of High-Gain Lasers, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

Semiclassical models for laser-dynamics studies typically incorporate a derivative approximation that reduces the second-order wave equation for the electric field to a first-order equation. It is shown here that this approximation and further frequency approximations are not necessary and may lead to significant errors for some high-gain laser systems. A more exact analysis also reveals a partial decoupling of the electric and magnetic fields that occurs with fast transient phenomena. These ideas are illustrated in terms of well-known dynamical effects.

Focal Point, Volume 05 Number 02, Portland State University. Regional Research Institute

Research and Training Center - Focal Point

In this issue of Focal Point we address the special needs of lesbian and gay youth and their families. The United States Department of Health and Human Services' 1989 Report of the Secretary's Task Force on Youth Suicide defines gay and lesbian youth as those who have a primary attraction to members of the same sex for intimate and sexual relationships (4). A variety of explanations have been offered to describe the origins of individual sexual orientation. While homosexuality may involve both elements of nature and nurture, the origins of sexual orientation are generally believed to be established during early …

Reciprocating Transformations, Joyce A. Bryerton

Dissertations and Theses

The paintings in this thesis project began with a study of various representational images, both personal and symbolic. It included the exploration of assorted media and different styles of execution in a search for imagery to represent the scope of my life experience. This search involved a method of working that excluded preconceived images. The original images evolved into an abstract state which alludes directly to the figurative and organic nature of the earlier work.

Rain, Eco-Net

RAIN: Journal of Appropriate Technology

Volume 14, Number 1

Inside: Decentralized Politics; The Natural Economy of Laos; Swiss Origins; The Oregon Experiment Revisited. Scanned from print copy loaned by Tom Bender

RAIN began in October 1974 as a publication of ECO-NET, an environmental education network funded by the Hill Foundation and an Environmental Education grant. Its office was based in the Environmental Education Center at Portland State University. With a focus on the Pacific Northwest, particularly Oregon, RAIN originally described itself as a “bulletin board” with an “emphasis on environmental/energy related and communications kinds of information” and interested in “the evolutionary possibilities of inter-disciplinary connections.”

An Exploratory Analysis Of Certain Characteristics Of Policewomen: A Second Look, Harry Oliver White Jr.

Dissertations and Theses

Female police officers are relatively new to the profession of law enforcement. Prior to 1968, the very few who were employed by police agencies were not permitted to perform the full range of police duties. Subsequent to that time their number has increased so that today they account for approximately 8.3 percent of the total sworn police population. There have been numerous studies which have attempted to identify the sociopsychological characteristics of male police officers. For example, Neiderhoffer reported in 1967 that male officers rate high in authoritarianism, anomia, job dissatisfaction, and choose police work for job security reasons. Very …

The Relocation Of North Bonneville, Washington, By The U.S. Army Corps Of Engineers: A Policy Implementation Study, Cecil Eugene Reinke

Dissertations and Theses

This is a policy implementation case study. The case is the relocation of the Town of North Bonneville, Washington, by the U.S. Army Corps of engineers. Three questions are addressed in this study. One, did the U.S. Army Corps of Engineers, in relocating the Town, accomplish what was intended to be accomplished? Two, how and why were Federal policies applicable to the relocation of this town changed during the implementation process? Three, what can the North Bonneville experience contribute to existent knowledge, understanding, and appreciation of policy implementation? The principal precepts for policy implementation promoted by this study of the …

The Archaeology Of The Longue Durée: Temporal And Spatial Scale In The Evolution Of Social Complexity On The Southern Northwest Coast, Kenneth M. Ames

Anthropology Faculty Publications and Presentations

The emphasis on temporal and geographic scale of the French Annales school of history (cf. Braudel 1980; Baker 1984; Lewthwaite 1988) is the inspiration for this paper. Braudel (1980) divides time into three durations: short term events (days, weeks, months, a few years), medium length conjunctures (years, decades, even major portions of centuries), and long term structures (which may last centuries, even millennia). This last duration is the longue durée. Basic to Annales' thought - and the longue durée - is the idea that to understand historical developments, to explain their causes and dynamics, one must know their temporal and …

Solvent And Substituent Effects On The Redox Potentials Of Several Substituted Tetraphenylporphyrins, Robert Arthur Ransdell

Dissertations and Theses

Tetraphenylporphyrins can be used to absorb visible light and pass on their excitation energy to electron transfer agents. The purpose of this research has been to investigate our ability to understand and control the energetics of porphyrin derivatives in order to use their electron transfer ability to harness the energy of sunlight. Shifts in the redox (reduction and oxidation) potentials of tetraphenylporphyrins result from variations in the substituents attached at the para- position of the phenyl rings of tetraphenylporphyrins, as well as variations in the state of ionization of those substituents, and the solvent in which the reactions are carried …

Development And Applications Of High Resolution Kinetic Atmospheric Pressure Ionization Mass Spectrometry In Atmospheric Chemistry, David Michael Myton

Dissertations and Theses

Much important work has been done to understand reaction pathways and identify products, yields, and reaction rates for atmospheric oxidation processes. Non-methane hydrocarbons (NMHCs) are the most significant of the organic compounds present in the atmosphere from a chemical perspective and are released into the atmosphere from both natural and anthropogenic sources. The oxidation of these hydrocarbons by hydroxyl radical HO generates products that may themselves be toxic, that play a major role in the formation of photochemical smog, and that to a lesser extent contribute to the formation of acid precipitation. NMHCs have chemical reactivities many times that of …

Formation Of Superhexagonal Chromium Hydride By Exposure Of Chromium Thin Film To High Temperature, High Pressure Hydrogen In A Ballistic Compressor, Yi Pan

Dissertations and Theses

The interaction of hydrogen with metals has great environmental significance in problems ranging from the catastrophic failure of materials due to hydrogen embrittlement to safe and efficient storage of hydrogen as a metal hydride. Chromium (Cr) is widely used as an alloying agent to produce materials such as stainless steel and as an electroplated coating on materials to prevent corrosion and to minimize wear. Hydrogen which co-deposits with chromium during electroplating forms hexagonal close packed CrH or face centered cubic CrH2 which cracks the deposit. The behavior of hydrogen in Cr, especially the crystal structure modifications of metal Cr when …

Freeway Control Via Ramp Metering: Development Of A Basic Building Block For An On-Ramp, Discrete, Stochastic, Mesoscopic, Simulation Model Within A Contextual Systems Approach, Mohamed Yaser Alkadri

Dissertations and Theses

One of the most effective measures of congestion control on freeways has been ramp metering, where vehicle entry to the freeway is regulated by traffic signals (meters). Meters are run with calibrated influx rates to prevent highway saturation. However, recent observations of some metering sites in San Diego, CA indicate that metering, during peak hour demand, is helping freeway flow while sometimes creating considerable traffic back-ups on local streets, transferring congestion problems from the freeway to intersections. Metering problems stem largely from the difficulty of designing an integrated, dynamic metering scheme that responds not only to changing freeway conditions but …

Adsorption To Dipalmitoylphosphatidylcholine Membranes In Gel And Fluid State: Pentachlorophenolate, Dipicrylamine, And Tetraphenylborate, Pavel Smejtek, S. R. Wang

Physics Faculty Publications and Presentations

We measured the dependence of electrophoretic mobility of dipalmitoylphosphatidylcholine (DPPC) vesicles on the aqueous concentration of negatively charged ions of pentachlorophenol (PCP), dipicrylamine (DPA), and tetraphenylborate (TPhB). The objective was to determine how the physical state of hydrocarbon chains of lipids affects adsorption of lipophilic ions. The studies were done at 25 and 42 degrees C to determine adsorption properties of DPPC membrane in the gel and fluid state, respectively. From the analysis of zeta-potential isotherms in terms of Langmuir-Stern-Grahame model we obtained the association constant, K, the area of the adsorption site, Ps, and the linear partition coefficient, beta. …

Otitis Media And Language Development In Late Talkers, Timothy Forest Lynn

Dissertations and Theses

While there is agreement in the literature that otitis media is an extremely prevalent disorder among young children, there is disagreement as to the effect that otitis media has on language development. The lack of definitive research attests to the complexity of the issue and to the need for continued research.

This study examined the relationship between an early history of otitis media and the language development of a group of "late talkers". The 28 toddlers in this group, while otherwise normal, were late to begin to speak. Each of the subjects was placed into one of two subgroups, depending …

The Electrokaryotype And Molecular Characterization Of Trypanosoma Cervi Isolates Using Recombinant Dna Techniques, J. Lindsley Bennett

Dissertations and Theses

The distribution of trypanosomes infecting wild ruminants of North America has only recently been investigated. Many isolates have been mensurally studied and were determined to be conspecific with Trypanosoma cervi. Widely divergent forms exist however, between host species and seasonally within a host. To determine the validity of all inclusions in the taxon and the extent of intraspecific variability, trypanosome isolates of moose, reindeer, antelope, muledeer, Roosevelt Elk and two discrete transplant populations of Rocky Mountain elk were characterized and differentiated using recombinant DNA techniques.
