The Electronic Instrumentation For Atmospheric Laser Propagation Studies, Clyde Manford Brown Jr.

Dissertations and Theses

The use of laser radiation in atmospheric communication systems is revealing new forms of signal degradation not previously encountered with lower frequency transmitting sources. The coherence and directivity of the laser which is responsible for its increased signal capacity is degraded by the effect of atmospheric distortion. Random fluctuations in the index of refraction (turbulence), Rayleigh scattering, aerosol scattering and other atmospheric effects create fluctuations (boiling, breathing, dancing, attenuation, transit-time dispersion, etc.) within the beam cross section, which when received produce random fluctuations in the receiver output signal. The two systems which are described, are designed to investigate the effect …

William Morris: Esthetic For Community, F. Eloise Taggart

Dissertations and Theses

This paper analyzes and evaluates William Morris’s esthetic for community. He presented this esthetic in lectures, letters, newspaper articles, and the dream novel of a happier future England, News from Nowhere. At the age of forty-three, after becoming an eminent poet and a well-known decorative design artist, he began to devote most of the last twenty years of his life to generating an interest in the better community. First, he worked with people of the upper and middle classes, then he turned his attention to the working men. I divide the analysis and evaluation of this work of William Morris …

Production Of A Thousand Clowns, Clifford John Sowle

Dissertations and Theses

The project chosen for partial fulfillment of the requirements for the degree of Master of Arts in Teaching in the field of Theater Arts was the production of Herb Gardner’s comedy, A Thousand Clowns. This particular play was chosen because it met production requirements more closely than any other script considered for the project. The project involved, after selection of the script, casting the characters, a six-week rehearsal period, consulting with the technical staff on matters of lighting, setting, and costumes, four performances at the Portland State College Idea Theater, two performances at the Oregon State Penitentiary, and the compiling …

Search For Quantum Oscillations In Field Emission Current From Bismuth., Donald Dean Casey

Dissertations and Theses

An experimental search based on previous published theoretical work was made for de Haas-van Alphen-like quantum oscillations in field emission current. The study was motivated by the possible applicability of de Haas-van Alphen measurements to the study of Fermi surfaces near real surfaces, Field emitters were fabricated from bismuth single crystals grown from the melt by a modified Bridgeman technique. Field emission current was measured with the field emitter cooled by contact with a liquid helium bath. Most measurements were made at 4.2° K, although a few measurements were made at 2.02°K; Fowler-Nordheim plots of the experimental current-voltage data were …

Precision Measurements Of The Mössbauer Fraction Of Fe⁵⁷ In Pt, Pd And Cu, Wilbur Lee Nees

Dissertations and Theses

Precision measurements of the Mössbauer fraction of the 14.4 kev Fe⁵⁷ transition were made using the black, wide absorber technique. The Fe⁵⁷ was diffused, as a dilute Mössbauer impurity, into 99.995% purity single crystal chips of Pt, Pd and Cu. By comparing the Debye form of -ln f, corrected for anharmonicity, with our data, we extracted a high and low temperature Debye theta, as well as an anharmonicity coefficient, є, for the three materials. We estimated the accuracy of our data to be ± 1%. From the data we concluded that the Fe⁵⁷ in Cu has stronger force constants and …

In-Service Education For Teachers Of Family Life Education From A Sociological Viewpoint, Helen M. Running

Dissertations and Theses

Harmony is found between a specific area of professional family life literature and the results of several surveys from within a particular metropolitan area. Revealed is a teacher inadequacy to the task of family life education in the primary and secondary schools. Deterrents are found to be a lack of both pertinent knowledge and skill.

Having shown consensus that the stated problem exists the further purpose of the thesis is to propose an aid to its remedy. Three factors require attention. Teachers need additional information from both the social and physical sciences. They need an opportunity to become aware of …

Bacterial Degradation Of Methyl Dehydroabietate, Burl C. Carter

Dissertations and Theses

Bacteria (Arthrobacter sp.), isolated from lodgepole pine (Pinus contortus), are capable of utilizing methyl dehydroabietate as the sole source of carbon. Degradation products of methyl dehydroabietate have been obtained by manually extracting the cell-free supernatant solution of a liquid growth medium with methylene chloride. Gas chromatography (G. L. C.) was used for separation of the neutral products. The acid products were converted to their methyl esters diazomethane and then separated by gas chromatography. Structures have been proposed for two G. L. C. fractions (V, II) on the basis of infrared (I.R.) and mass spectral (M. S.) data. …

The Identification Of The Inorganic Components In The Calcareous Corpuscles From Mesocestoides Corti, Larry M. Kegley

Dissertations and Theses

The inorganic components in calcareous corpuscles from Mesocestoides corti have been identified by use of powder x-ray diffraction and emission spectroscopy. Difference methods were compared for the isolation of the calcareous corpuscles from the residual tissue of the Mesocestoides corti. Previously reported and newly developed methods for the isolation are discussed.

Analyses by powder x-ray diffraction for in vivo samples which had been heated at various temperatures ranging from room temperature to 1000°C are reported.

The qualitative emission spectrographic analyses for in vivo and in vitro corpuscles are reported for normal systems and systems designed to study the ion …

Verbal Accessibility Between Marital Partners As Studied In A Court Of Domestic Relations, Patricia Walker

Dissertations and Theses

This study investigated the concept of verbal accessibility in marriage. It is an example of the interactional approach to the study of marriage, which is concerned with the on-going socialization process in marriage. Verbal communication is one component of the socialization process and also of problem solving in marriage.

Interpersonal communication is influenced by many variables--personality, culture and social situation. Polansky (1965) conceptualized verbal accessibility as the degree of readiness to communicate verbally and to participate in communication about determinant attitudes. Determinant attitudes are those which have the most far reaching influence on other attitudes and on behavior.

One of …

Assessment Of Subjective Experiences Of Boys Entering The Community From A Correctional School, Thomas W. Dejardin

Dissertations and Theses

The purpose of this study was to explore, classify, and evaluate the personal experiences of juvenile offenders following release from a state training school.

During a two month period beginning in the fall of 1967, a group of twenty-three releasees from the MacLaren School for Boys in Woodburn, Oregon were interviewed on a weekly basis in the Portland metropolitan area. The boys, ranging in age from thirteen to seventeen were contacted in their homes, schools, and other settings to learn of positive, negative, and critical experiences encountered in the community.

Open ended questions based upon a twenty- seven item schedule …

The Development Of A Clay Body With Compatible Glaze Formulae, Nancy Travers

Dissertations and Theses

There are two aims in this thesis: the first is to ascertain something of the physical and chemical properties of clay and glazes and how to handle and control them. A project such as the development of a clay body and glaze formulae serves to isolate the various functions of the materials and give a clear understanding as to their use and potentials. This enables one to visualize and manipulate materials creatively with a reliable prediction as to their behavior. Spencer Moseley in Art Education supports this, saying: "The quality of a man’s production depends upon (1) the idea, the …

Theoretical Calculations Of Kinetic Isotope Effects, Paul Chien-Wei Chang

Dissertations and Theses

Treating the activated complex for unimolecular dissociation as uncoupled fragments simplifies the calculation of transition-state frequencies in the quasi-equilibrium-theory formulation of an isotopic rate-constant ratio. The general method is applied to the specific case of the intramolecular kinetic isotope effect in decarboxylation of malonic acid. The fragment models are further simplified by means of the “cut-off” approximation of Sterm and Wolfsberg. These model calculations are in agreement with the presently available experimental results. Applicability to reactions involving simultaneous multiple bond rupture or formation is noted.

The Gaussian Mode In Optical Resonators With A Radial Gain Profile, Lee W. Casperson, Amon Yariv

Electrical and Computer Engineering Faculty Publications and Presentations

The dependence of the parameters of the Gaussian mode in laser resonators on the properties of the medium in the cavity is studied. Experimental verification of the theoretical results is presented. It is found that the modes in a high‐gain laser may differ widely from the usual free space resonator results. Also, resonator configurations which in free space are unstable may, with a suitable medium, support low‐loss Gaussian modes.
