Growth Of Selenastrum Capricornutum Printz In Natural Waters Treated With Copper Sulfate, Gerald Eugene Schulz

Dissertations and Theses

The green alga, Selenastrum capricornutum Printz, was used in an algal bioassay to determine the toxic properties of copper in various natural lake waters of Oregon. Lake water was collected and brought back to the laboratory where it was treated with various copper concentrations and inoculated with a cell suspension of the test alga. Growth of the alga was determined by direct cell counts. The copper ion activity, pH, and absorbance of the test cultures were also determined. The growth of the alga was found to depend upon the water tested and also upon the copper concentration used.

Ernst Cassirer And The Synthesis Of The Past: A Paradigm In The History Of Ideas, Mart Stewart

Dissertations and Theses

The problem of a method of historical analysis played an integral part in the scholarship of Ernst Cassirer, German philosopher and historian. An Essay on Man, the work for which he is best known in the United State, includes his most lucid discussion of the tasks and aims of the historian. The historian must reconstruct the past, infusing it with the immediacy of a living expression. "Rebirth of the past" gives man a better view of his potentialities, a freedom to see beyond the demands, characteristics, and contingencies of the moment.

This view of history and the historian's task …

Two Delivery System Contexts For The Elderly:The "Institutional" Approach And The "Community" Approach., Mary Sarita Freer

Dissertations and Theses

Theoretically every society has some institutional means which seeks to prevent and alleviate personal misfortune and illness "Institutions are standardized solutions to collective problems." The increasing population rate of older persons, many of whom suffer from chronic diseases and disabilities, does pose a collective problem for society. Formerly, the "institutional" approach developed to address the needs of chronic aging patients and society. Today the "community" approach, by which community service agencies whose goal is to help older adults remain independent of total institutional care by supplying supportive services, is achieving recognition .

This thesis is an exploratory study to assess …

The Origin Of Property In Land: Paul Vinogradoff And The Late Xixth Century English Historians, Caroline Phillips Stoel

Dissertations and Theses

One of the problems which has intrigued English historians for over a hundred years is that of the position of the common man in early England. Was he a freeman working land held communally by the village, or was he a serf laboring upon the land of an overlord? Since this question of freedom is inextricably interwoven with landholding concepts the problem may also be stated another way: Did private property in land exist from the earliest times, or is that institution the result of centuries of appropriation by individuals of land originally belonging to the commmunity as a whole? …

Contributions Of Peter Pallas To Science And Exploration In Russia, Robert C. Parker

Dissertations and Theses

This thesis presents an account of a prominent eighteenth-century European naturalist, Peter Pallas (1741-1811), in the setting to which he contributed his scientific talents--the St. Petersburg Academy of Sciences. A complete outline of Pallas' life is presented for purposes of continuity, but the heart of the thesis is presented in chapters four and five, which combined, relate the major features of Pallas' career in Russia. These two chapters are set against pertinent background material, most of which is involved with the institution itself which supported Pallas. The St. Petersburg Academy of Sciences is surveyed in its origin and development in …

Response Of Orthotropic Bridge Decks To Highway Loadings, Harry Morris Rexin

Dissertations and Theses

This thesis documents the fabrication, testing techniques, and response of a plastic scale model of an orthotropic bridge deck. To economically investigate a two-lane steel bridge deck, plastic Acrylic^R was used as a modeling material. Welds were simulated with dichloromethane, a capillary action solvent, and PS-30, a polymerizable cement. Deflections were measured with laboratory dial guages while strains were monitored with strain guages mounted on the deck.

The response of the deck to AASHO vehicle axle loads was compared with a discrete element computer program used to analyze orthotropic bridge decks continuous over flexible supports. Results indicate good correlation …

A Theory Of The Creativity-Intelligence Interaction: An Environmental Suppressor Variable, Lynda L. Mcdonald

Dissertations and Theses

In a commonly held view, creativity and intelligence interact in a mutually enhancing way. Their interaction, however is assumed to be slight and relatively unimportant, and to find its ceiling at a certain IQ level. Beyond this IQ ceiling, no interaction is believed to occur, and the two variables are assumed to be independent. It is suggested that this view and those theorists who hold it do little to explain the reason for the ceiling effect.

An attempt is made to devise a theoretical system which accounts for a explains the ceiling effect, as well as providing new ground for …

Possible Avian Influences In The Distribution Of Dwarf Mistletoe, Paul James Zilka

Dissertations and Theses

The goal of this investigation was to determine the potential of birds as vectors for the movement of dwarf mistletoe seeds and the means by which such movement could occur. Birds would greatly speed the rate at which these parasites move horizontally or vertically through the forest. Five areas in Oregon, heavily infected by six species of Arceuthobium were studied. Observations of avian behavior point to 13 species whose general behavior make them potential vectors in the distribution of these parasites. More specifically, the roosting and subsequent bathing behavior of most forest birds proves a very important means of potential …

The Doctrine Of Experience In The Philosophy Of Jonathan Edwards, Puritan Divine, Joseph S. Trachtenberg

Dissertations and Theses

A number of basic themes suggest themselves as focal points for a study of the thought of Jonathan Edwards. The dissertation is an attempt to argue that experience is one of them, and that an attentive eye to the doctrine of experience will reveal it as the unifying theme of his philosophy. Specifically, at the center of Edwards' aesthetic and religious vision there lies a rich and profound sense of experience, and of the relation of all things to some form of perception.

The evidence is to be found in Edwards' extensive published and unpublished writings. Among the several editions …

Between Words And Actions: The Problem Of Motivation In Symbolic Interactionism, Robert Scott Broadhead

Dissertations and Theses

The development of a theory of motivation in symbolic interactionism is traced, with particular reference to the work of G.H. Mead, Kenneth Burke, C.W. Mills, Nelson Foote, and Ernest Becker. Specific attention is focused on comparing the original theoretical assumptions of particularly Mead and Burke to the varying formulations of the problems of motivation that were later developed by symbolic interactionists. Specifically, it is argued that, primarily due to Burke's analysis, the traditional practice of deterministically explaining human action as being the result of variously imagined motives "in" people is, in fact, no explanation at all but simply a variety …

Purification And Characterization Of Dihydroorotase From Clostridium Oroticum, A Zinc-Containing Metalloenzyme, William Edward Balch

Dissertations and Theses

Dihydroorotase (4,5-L-dihydro-orotate amidohydrolase, EC 3.5.2.3) which catalyzes the reversible cyclization of N-carbamyl-1-aspartate toL-dihydro-orotate has been purified from orotate-grown Clostridium oroticum by a combination of streptomycin sulfate fractionation, DEAE-Sephadex chromatography, and hydroxylapatite chromatograpy. The enzyme has been shown to be omogeneous when subjected to polyacrylamide gel electrophoresis. Thin-layer gel chromatography with Sephadex G-200 indicated the enzyme to have a molecular weight of 110,000 ± 10,000. Sodium dodecyl sulfate gel electrophoresis using two different buffer systems indicate the enzyme to be composed of two identical subunits with a molecular weight of 56,000 ± 5300. Dihydroorotase has been shown to be a zinc-containing …

A Study Of The Problems Of Translation, Rhetorical Analysis, And Translation Of A Speech Of Mohammed Mossedeq, Gholamhosain Janati-Ataie

Dissertations and Theses

Through the translation and analysis of a major speech, the political thought and rhetorical devices of Mohammed Mossedeq, former Prime Minister of Iran (1951-1953), are examined. Just as cultural and philosophical differences account for many problems in such a translation, so have they led to Mossedeq's being largely misunderstood in the West. The study therefore presents a more positive view of Mossedeq, emphasizing his nationalism, which has inspired countless movements toward independence among the Third World nations. Chapters deal with the background of the study, problems of translation (including the semantic and lexical nonequivalences between languages, as well as cultural …

An Investigation Of Handedness And Its Relationship To The Site Of Contact Ulcers, Colleen S. Colleary

Dissertations and Theses

This investigation attempted to determine the relationship of the site of contact ulcers and subject’s handedness. Literature concerned with contact ulcers has indicated that cerebral dominance tends to determine the site of the lesion. Four research questions were posed, two questions were presented in the form of the null hypothesis. The questions were: (1) Is the proportion of right-handed subjects with left-sided ulcers equal to the proportion of left-handed subjects with left-sided ulcers? (2) Is the proportion of right-handed subjects with right-sided ulcers equal to the proportion of left-handed subjects with right-sided ulcers? (3) Will the site of contact ulcers …

Effects Of Speaker-Sex-Difference On Listeners' Perception Of Vocal Roughness In Normal Vowel Productions, Patsy J. Phillips

Dissertations and Theses

The purpose of this study was to investigate the effects of speaker-sex-difference on listeners' perception of vocal roughness in the vowel [ӕ] produced by normal male and female speakers. In a previous investigation by Wendahl (1963) it was found that when listening to two synthesized vowels, of equal aperiodicity, judges tended to rate the lower pitched vowel as being more vocally rough. If this is true for listeners' perception of human vowel productions as well then it might be advantageous for voice clinicians, when making vocal roughness assessments, to regard male and female speakers as two separate populations in view …

Granulometric Analysis Of Recent Sediments Of Tillamook Bay, Oregon, Gennaro William Avolio

Dissertations and Theses

The author has sampled the recent bottom sediments in Tillamook Bay, Oregon. Sediment distribution is assessed in relation to sediment source areas and related to sedimentary environments. Particular attention was directed to the precision with which granulometric data can be stated. It was found that variance is quite high for granulometric parameters of the bay sediments.

Sediment distribution using different measures are displayed on charts of the bay. Size distributions of sediments at any given location are examined for geologic significance. Plotting of size distribution on graph paper using probability ordinate is shown to increase the ease of geologic interpretation. …

The Diplomatic Stalemate Of Japan And The United States: 1941, David Hoien Overby

Dissertations and Theses

This thesis contends from the time of September 1940 to the Japanese attack on Pearl Harbor, the United States and Japan offered each no workable concessions that might have deterred war. A stalemate was finally established between the two countries. The position of the Japanese nation was to expand and control "Greater East-Asia," while the position the United States held was one that claimed all nations should uphold certain basic principles of democracy, that all nations should honor the sanctity of treaties," and that they should treat neighboring countries in a friendly fashion.

This thesis also contends that Yosuke Matsuoka …

An Experimental Study And Analysis Of Saudi-Arabian - American Proxemic Behavior As Observed In Homogeneous And Heterogeneous Dyadic Interactions, Gary D. Robinson

Dissertations and Theses

This thesis is an attempt to refine the analysis of an empirical study in intercultural proxemic behavior research conducted by Watson and Graves and is, as well, a partial and modified replication of that study. The hypothesis of this, study is that Arabs will exhibit significant differences in proxemic behavior from Americans, with Arab's being closer and more direct in their proxemic, behavior than Americans. To test this hypothesis eighteen Saudi-Arabian and eighteen American male students were observed as two groups of nine homogeneous dyads and as one group of eighteen heterogeneous dyads.

Seven-minute dyadic interactions in a controlled, laboratory …

Family Variables Which Are Associated With Achievement Of Community Tenure By Persons Released From Psychiatric Hospitalization, Thomas Mack Chambers

Dissertations and Theses

The pattern of frequent discharges and readmissions which characterizes most psychiatric hospitalization in this country today was described, and it was argued that the costs of this "revolving door" outweigh such benefits as might be derived from it. An alternative stepwise progression model of aftercare was proposed. This model identified community tenure as the most appropriate goal for initial aftercare efforts.

Attempts to identify correlates of the establishment of community tenure by mental hospital releasees were reviewed. It was found that the ex-patient's ability to remain in the community is not highly correlated with the extent to which he manifests …
