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 …

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.

The Sasswood Ordeal Of The West Atlantic Tribes Of Sierra Leone And Liberia: An Ethnohistoriographic Survey, Sarah Louise Davies

Dissertations and Theses

The sasswood ordeal of poison presents a divinatory ritual which has been used in criminal cases by the traditional African of Sierra Leone and Liberia. For at least six hundred years, the peoples of these present countries have imposed this strictest of ordeals on their moral transgressors; and the practice has survived, despite the protestations of nineteenth-century missionaries and the encroachment of the western world.

The investigation of the historical evidence of the sasswood ordeal among the West Atlantic tribes of Africa has three basic purposes. First, because of the paucity of interpretive data on the sasswood ordeal, the primary …

A Test Of The Simple Recessive Hypothesis For The Inability To Taste Phenyl-Thio-Urea: A Family Study, Susan I. Wolf

Dissertations and Theses

This thesis is a report on the analysis of family data gathered to test the simple recessive hypothesis for the inability to taste phenyl-thio-urea (P.T.C.). The simple recessive hypothesis states that the inability of a minority of persons to taste high concentrations of P.T.C. is due to the action of an autosomal recessive gene in the homozygous condition.

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.

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 …

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 …

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 …

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 …

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 …
