A Study Of The Adsorption Of Some Atmospheric Gases On Soils Of The Willamette Valley River Basin, Thomas R. Quale

Dissertations and Theses

Recent work indicates that microorganisms present in soils can remove carbon monoxide from the atmosphere and as such constitutes a major sink. B.E.T. adsorption studies were carried out on representative soils from the Willamette Valley River Basin in order to determine their adsorptive characteristics for carbon monoxide and other gases. Attempts were made to isolate, through a non-soildestructive sterilization, the adsorptive characteristics of the soil microorganisms as well as of the test soil.

The carbon monoxide studies show physical adsorption equivalent to the coverage of a few per cent of the surface area at 25.0° and 76 cm-Hg. Adsorption studies …

Experimental task 2 contained two word picture sets of high, moderate, and low SAS words, and experimental task 3 contained three word picture sets of high, moderate, and low SAS words. Subjects heard one, two, and three word verbal sequences …

Differences Between Supervisor And High And Low-Rated Employees' Perceptions Of Job Performance Ratings And Importance Of Job Factors, Harvey Edward Mcgowan

Dissertations and Theses

This study was an attempt to gain insight into differing conceptions of job performance and job performance factors held by supervisors, employees in general, and of employees rated high and low on overall job performance by their supervisors. The discrepancy in the perceptions of job performance is an element in a general pattern of a well-documented discrepancy in the perception of subordinates' wants, needs and desires by superiors.

To assess employees' perceptions about their own job performance, self-ratings were taken, along with estimate ratings of how employees thought their supervisors would rate them. A graphic rating scale was used, Format …

French-Indian Relations (1672-1701): An Economic, Political And Military Study, James Duncan Biggs

Dissertations and Theses

This paper concentrates on the political, economic, and military policies of New France (French Canada) towards the Indian tribes inhabiting and bordering New France during the period 1672-1701. It was a period of intensive exploration coupled with the fur trade, principally beaver, both of which activities spurred France to compel its "province" of New France to make alliances with the Indians and to block penetration of the French-claimed area by the English colonists to the south (New York and New England) and to the north (Hudson's Bay area).

Any research must be concerned with many interacting and conflicting factors: the …

A Study Of The Speech Philosophy Of Alexander Campbell And The Application Of That Philosophy, Rudy L. Morrow

Dissertations and Theses

A great religious Awakening was taking place in 1805 until the end of the Civil War. Religious debates became the order of the day, and were at least equal in importance to the political debates. Alexander Campbell was one of the leading debators of the period. He was born September 12, 1787, in Ireland, but moved to America in 1809, settling in western Virginia. In 1812, Alexander and his father, Thomas Campbell, launched what they called "The Restoration Movement", in which they were seeking for the unity of all Christians on the basis of the Bible.

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.

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 …

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 …

A Tectonic Study Of A Part Of The Northern Eagle Cap Wilderness Area, Northeastern Oregon, Kenneth Gordon Neal

Dissertations and Theses

Upper Triassic metavolcanic and metasedimentary strata in the study area are intruded by the Hurricane Divide and Craig Mountain Plutons of the Late Jurassic-Cretaceous Wallowa Batholith. The Clover Creek Greenstone is overlain by the Martin Bridge Limestone, which is in tum overlain by the Hurwal Argillite; although the sequence is in normal stratigraphic order, contacts are generally tectonic. Concurrent with Early-Middle Jurassic regional deformation, during intermediate to mafic dikes, emplacement of the plutons of the Wallowa Batholith began. The plutons intruded vertically through the greenstone and limestone and then horizontally above the greenstone. This resulted in intense penetrative plastic deformation …
