Alumina-Catalyzed Cope Rearrangement, Paul Jhy-Shing Wang

Dissertations and Theses

The alumina-catalyzed Cope rearrangements of meso- and dl-3,4-diphenylhexa-1,5-diene were examined in detail, following up a preliminary observation by H. Berg at Portland State University. Commercial column-chromatography grade alumina was employed, and was further activated before use by heating at 650-700° for four hours.

Using a ratio of 20 mg of dl-3,4-diphenylhex-l,5-diene to 1 g of alumina in heptane, the Cope rearrangement was complete within 15 minutes at room temperature to give exclusively trans,trans-1,6-diphenylhexa-1,5-diene. This was identified.by melting point, infrared spectroscopy and vapor phase chromatography.

The catalyzed rearrangement of meso-3,4-diphenylhexa-l,5-diene was run using the same diene …

A Study Of Rna Bacteriophage 7s Infection Of Pseudomonas Aeruginosa, Deanne Benson

Dissertations and Theses

A study was conducted to find the effect of magnesium, calcium, manganese and zinc ions on the infection of Psudomonas aeruginosa strain 1C by RNA bacteriophage 7s. When an 18 hour progeny experiment was performed, it was found that magnesium, calcium and manganese had different effects on bacteriophage production and was dependent on the bacterial growth conditions. RNA bacteriophage 7s progeny production was significantly enhanced by the addition of magnesium to cultures of Psudomonas aeruginosa 1C grown in a magnesium deficient medium. Under these environmental conditions there was a slight increase in progeny in the presence of calcium. When Psudomonas …

The Effects Of Pentachlorophenol On The Electrical Conductivity Of Lipid Bilayer Membranes, William Harvey Perman

Dissertations and Theses

The effects of pentachlorophenol (PCP), a widely used pesticide, on the electrical characteristics of lipid bilayer membranes has been studied. When a small amount of PCP (even at a concentration of a few micromoles per liter) is present in the electrolytic solution surrounding the membrane, the electrical conductivity of the membrane significantly increases. The present work was concerned with detailed measurements of the changes in the conductivity caused by PCP under chemically controlled conditions. The experimental results were analyzed to determine the permanent species in the membrane, and an attempt was made to correlate the data with existing models of …

The Historical Imagination Of Francesco Petrarch: A Study Of Poetic Truth And Historical Distortion, Sally Scholz

Dissertations and Theses

In the continuing debate among historians over the nature, if not the actual existence, of the Italian Renaissance, the life of Francesco Petrarch has played a major role. Petrarch was an outspoken critic and commentator on the state of fourteenth-century society. His opinions have been cited by all scholars interested in the origins of the "Renaissance Mind."

The concern of this paper will be to discuss the sources, development, and purpose of Petrarch's historical imagination. By tracing the course of Petrarch's life I have tried to expose the various factors bearing on his psychological development. His "exile" from Italy, early …

Eutamias Minimus And E. Amoenus: Morphological Cluster Analysis, Sandra Elaine Anderson

Dissertations and Theses

Cluster analysis of a large body of data on 180 Oregon specimens of Eutamias minimus and E. amoenus suggest that overall length of skull, basal length of skull and length of palate are taxonomically critical. If their sum is less than 71.3 millimeters the animal is E. minimus. If the sum is greater than 72.7 millimeters the animal is E. amoenus. If the sum is between 71.3 and 72.7 millimeters, other factors must be considered before the animal can be identified. Of the 180 specimens, there were 60 E. minimus, 114 E. amoenus, 2 hybrids, 2 …

Enzyme Reactions Using Ureidosuccinate As A Substrate During Pyrimidine Biosynthesis And Degradation In Cl. Oroticum, Penny Amy

Dissertations and Theses

Cells of Clostridium oroticum, an anaerobic bacterium, were grown on orotate as a carbon and energy source. Ureidosuccinase, an inducible enzyme in the pathway for pyrimidine degradation has been shown to convert ureidosuccinate to aspartate, CO₂ and NH₃ as reported by Liebenmm and Kornberg (7). Aspartate and CO₂ were formed in approximately a 1:1 ratio from ureidosuccinase activity.

Ureidosuccinase was found to be a Mn+² requiring enzyme with a pH optimum of approximately pH 6.5. Enzyme activity is labile to O₂, temperature, pH, dilution and high ionic strength. The optimum conditions for storage …

A Historiography Of The Elizabethan Poor Laws: Late Xixth And Xxth Century Historians, Susan C. Mcnaught

Dissertations and Theses

The Elizabethan poor laws stand as a great work from a dynamic period. How and why they were formulated have been questions which historians have asked for centuries. The discussions of these questions have varied, depending on the personal values and biases which each historian brought to this study. It is generally agreed that a very important function of the historian is interpretation. The study of history is not only a study of the events, but a study of the historians and their differing interpretations of those events.

In the past one hundred years, numerous historians have devoted themselves to …

James Butler And The Royalist Cause In Ireland, 1641-1650, Monica A. Brennan

Dissertations and Theses

On June 19, 1647 Ireland's Lord Lieutenant, the Marquis of Ormond, unconditionally surrendered the city of Dublin to the parliament of England. Ormond's biographer, Thomas Carte, records that in January of this year the marquis received a private dispatch clearly indicating Charles I's pleasure -- if it were impossible to hold Dublin and the other royalist garrisons in his name they were to be surrendered to the English rather than the Irish. The loss of the major royalist stronghold in Ireland proved, in effect, to be the turning point of the war in that kingdom; its loss has given Ormond's …

The Correlation Between Specific Curiosity And Intelligence In Adults, Charles R. Schwenk

Dissertations and Theses

Previous studies done on the correlation between specific curiosity and intelligence have been inconclusive. In the present study, a test of state specific curiosity and a test of intelligence were administered to 76 Ss from two introductory psychology courses. Three hypotheses were tested. These were, (a) that a significant specific curiosity-intelligence correlation would exist, (b) that the specific curiosity-verbal subscale correlation would be higher than the specific curiosity-abstraction sub-scale correlation, and (c) that there would be a sex difference in the specific curiosity-intelligence correlations. The data did not support hypothesis (a) or (b). However, they did support hypothesis (c). …

Probability Driven Heuristic Nets, Lynn Robert Carter

Dissertations and Theses

Let a probability driven switch be defined as a switch of three input paths and three output paths. The status of the input paths defines a probability for each output path (as to whether it will generate a signal or not.) One output path is linked to one input path, so the results of the switch at time t can affect the switch at time t+1. A switch so constructed can be defined (by the probabilities) to take on the function of the standard logic gates (AND, OR, …) A net constructed of these switches can be “taught” by …

Chicanos In Oregon: An Historical Overview, Richard Wayne Slatta

Dissertations and Theses

Spaniards were the first Europeans to explore the Pacific Northwest coastline, but the only evidence of these early visits is a sprinkling of Spanish place names commemorating the intrepid voyagers. The more than four centuries of recorded history since that time are nearly devoid, of references to Spanish-speaking people, especially Mexicans and Americans of Mexican descent (Chicanos). Even the heavy influx of Chicano migrant farm workers in the 1950's and 1960's failed to attract the attention of historians or social science researchers. By 1970, the Spanish-language population had become Oregon's largest ethnic minority and was exerting influence in most areas …

An Investigation Of Infection Mechanisms Of Arceuthobium Campylopodum, Annabella Jaramillo Garcia

Dissertations and Theses

Wound periderm is formed by Juniperus occidentalis and Calocedrus decurrens in resistance to infection by the dwarf mistletoe Arceuthobium campylopodum. The pattern of wound periderm formation suggests that chemical as well as mechanical factors are involved. The concentration of hydrolases in the radicular apex of the parasite suggests that they may facilitate the penetration process by which dwarf mistletoes infect their hosts. Emzymatic assistance may also provide a partial explanation for the specificity with which dwarf mistletoes are adapted to given hosts. These resistance responses by the the non-host species were compared with the normal infection process Pinus ponderosa …

Gutzkows Novelle Der Sadduzäer Von Amsterdam Verglichen Mit Seinem Drama Uriel Acosta Und Eine Englische Übersetzung Der Novelle, Clarice Solberg Kitteleson

Dissertations and Theses

The same theme of one unorthodox man opposing a self-appointed authoritative religious institution is interpreted in two different ways in two related works by Karl Friedrich Gutzkow: his Novelle, Der Sadduzaer von Amsterdam (1834), and in his drama, Uriel Acosta (1846). Both works fictionalize the life Uriel Acosta (1585-1640), an unorthodox Jew who fled the Spanish Inquisition in Portugal to the relatively tolerant country of Holland. Acosta's problems were not with the government of Holland, however, but with his own orthodox Jewish temple authorities. He opposed the written interpretations of the Talmud and attempted to question the very idea of …

Infection Of Smallmouth Bass And Goldfish By Two Species Of Saprolegnia, Cheryl A. Mcginley

Dissertations and Theses

This study consisted of several experiments designed to compare the ability of two species of fungi, Saprolegnia ferax and S. parasitica to grow on two species of fish, smallmouth bass (Micropterus dolomieui) and goldfish (Carassius auratus), and to determine the criteria necessary for the development of these infections.

The results indicate that water in the fish tanks must be slightly acid (pH 6), warm (22°C), nonmoving, and that the fish must be wounded in order for fungal infection to occur. Cool water (18°C) and moving water, caused by aeration and filtration, are detrimental to fungal colony …

The basic question posed was: What sources of information are most commonly utilized by a sample of Oregon’s population in obtaining ideas and information concerning the wildlife resource and do the proportions of various sources utilized compare with those indicated by college students as sources of anti-hunting sentiments?

Additional questions …

Effects Of The Nerve During The Dedifferentiative Phase Of Limb Regeneration In The Mexican Axolotl, Ambystoma Mexicanum, Roberta Gail Wald

Dissertations and Theses

It is known that nerves are particularly critical during the early or dedifferentiative phase of limb regeneration. During this period in the innervated limb, cells just proximal to the amputation surface dedifferentiate, migrate to the limb tip, and undergo mitosis. These processes give rise to a population of undifferentiated mesenchymatous cells capable of redifferentiating into the missing components of the newly forming regenerate. The consequences of denervation stand in stark contrast to the normal events occurring in the innervated limb, because neither a blastema nor a regenerate forms.

Results from this study indicate that during the early portion of the …

Partisan Voting In The Oregon Legislature, Tom Lee Mason

Dissertations and Theses

The thesis examines the role of partisanship in two sessions of the Oregon Legislature. Both the Oregon Senate and the Oregon House of Representatives were examined for the 56th (1971) and the 57th (1973) session. Indicies of partisanship, or party cohesion were developed for both parties in both houses during both sessions. Each legislator was also assigned an index of partisanship. The indicies of partisanship for the parties were the average percentage of the members of the two parties voting together on those issues which underwent "party votes." A party vote was defined as any vote on which the majority …

Negotiation Within The Therapist-Client Interview, Rhoda Elaine Estep

Dissertations and Theses

This thesis combines a theoretical perspective and a methodological technique in order to clarify the concept of negotiation. The theoretical perspective represents a merging of a formal analysis as suggested by Georg Simmel and Erving Goffman and an interactional emphasis upon reciprocity of actions as proposed by Herbert Blumer. Accordingly, a methodological scheme was constructed to examine negotiations in terms of their forms and content.

Differential Measurement Of A Language Concept Presented Via Video Tape Playback To First Grade Students, Richard Warren Trullinger

Dissertations and Theses

Educational television began in 1932 at the State University of Iowa. Until 1952, the potential of its contributions to education were not fully recognized. In 1952, however, the Federal Communication Commission created non-commercial television station. From that point in time, educational television has mushroomed.

This study tested the hypothesis: At least 80 percent of a given first grade population will respond accurately to the post-testing of a language concept, after the concept has been presented to them via a video tape playback using puppetry as the teaching method. In essence, the study was designed to determine whether or not an …

The focus of this research is the relationship between the supply of registered nurses and the rate of return on the educational investment to become a registered nurse. Is this rate of return a determining factor in the supply, past, present, and future? Since 98. 8 percent of all registered nurses are women, an integral part of this study is a survey of the data on women in the labor force.

The empirical data, statistical, was obtained from government sources and non-government associations, The American Nurses Association, The American Hospital Association, and the educational institutions. The data indicates the following: …

Danish Day Care As A Social Institution, Albert Sessions Belais, Ellane L. Kibel

Dissertations and Theses

A study of the social and cultural aspects of day care in Denmark. The thesis hypothesizes that experiences in the development of Danish day care are relevant to the future development of day care in the United States.

Interest in Danish day care was stimulated by the reports of Drs. Marsden and Mary Wagner (1970) which found Danish day care provided an intimate and innovative standard of care for young children.

Twenty centers of widely varied types were visited in Denmark. Information was gathered largely through unstructured interviews with child care staff and non-participant observation. Special attention was paid to …

The Background And Development Of The 1871 Korean-American Incident: A Case Study In Cultural Conflict, Robert Ray Swartout Jr.

Dissertations and Theses

This study is an attempt to combine the disciplines of Asian history and United States diplomatic history in analyzing the 1871 Korean-American Incident. The Incident revolves around the Low-Rodgers expedition to Korea, and the subsequent breakdown of peaceful negotiations into a military clash of arms.

To describe the Incident as merely another example of American "imperialism,'' or as a result of narrow-minded Korean isolationism, is to oversimplify its causes and miss the larger implications that can be learned from it. A basic premise of this paper is that the 1871 Incident is an example of East-West cultural conflict. As such, …
