Modes Of A Laser Resonator With A Retroreflecting Corner Cube Mirror, Guosheng Zhou, Anthony J. Alfrey, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

The self-consistent integral equation for the field distribution of the resonant modes in a resonator with a tilted retroreflecting corner cube mirror is solved. The corner cube acts like a convex lens with radius of curvature -L cot²Ө in the rotation direction (L is the cavity length and Ө the rotation angle) and like a flat plane in the direction of the rotation axis. The field distribution can be described in terms of Hermite-Gaussian functions, and these results have been confirmed experimentally using an Ar-ion laser. The equivalent beam matrix for a reflecting corner cube is also found.

RAIN began in October 1974 as a publication of ECO-NET, an environmental education network funded by the Hill Foundation and an Environmental Education grant. Its office was based in the Environmental Education Center at Portland State University. With a focus on the Pacific Northwest, particularly Oregon, RAIN originally described itself as a “bulletin board” with an “emphasis on environmental/energy related and communications kinds of information” and interested in “the evolutionary possibilities of inter-disciplinary connections.”

Teaching Figure Drawing To Adolescents Within The Context To [I.E. Of] Imaginative Compositions, As A Means Of Increasing Artistic Confidence And Abilities, Christine Flavell Turner

Dissertations and Theses

This thesis describes a process of teaching figure drawing to adolescents which places importance on the subjective experiences of the students. Traditional figure drawing methods emphasizing the development of visual perceptual skills are integrated with activities which are designed to secure emotional participation, and develop awareness of art as a means of expression and communication. This approach seems to motivate students and to reduce the anxiety usually experienced by adolescents when they are drawing the figure.

Speech Intelligibility As A Function Of The Propositionality Of Background Noise, Gail Swanstrom

Dissertations and Theses

The purpose of this investigation was to measure the ability of young normal hearing listeners to perceive speech in the presence of a background noise which varies in the relative intensity of its semantic content. The Speech Perception in Noise test was mixed with a two-component competing noise complex in which the narrative-to- speech noise ratio varied in 2 dB increments from -2 dB Na/SpN to +8 dB Na/SpN. These stimuli were presented at an overall +8 dB signal-to-noise ratio to thirty young normal hearing adults through the soundfield system. The differences between the mean error scores and standard deviations …

Kinetics Of Proton Transport In Lipid Membranes Induced By Some Chlorinated Phenols, Ananda Ranjith Jayaweera

Dissertations and Theses

This dissertation represents an attempt to understand the mechanism of the action of pesticides derived from chlorinated phenols (pentachlorophenol, pentachlorobenzenethiol, and 2,4,5-trichlorophenol) in lipid membranes; specifically, the kinetics of pesticide induced hydrogen ion transfer in lecithin-cholesterol membranes and its relationship to uncoupling activity in energy transducing membranes. Information on pesticide induced charge transport in membranes was obtained from the measurements of steady state and transient membrane conductance and membrane potentials as a function of the composition of the aqueous phase surrounding the membrane and of membrane composition. In addition, a systematic theoretical study of a series of membrane transport models …

Iron Acquisition By Cyanobacteria: Siderophore Production And Iron Transport By Anabaena, Peter James Lammers

Dissertations and Theses

The cyanobacterium Anabaena sp. (PCC #6411) is known to produce the siderophore, schizokinen, in response to iron limitation. Environmental factors which influence schizokinen production have been examined utilizing a bioassay method based upon the stimulation of growth of the siderophore-requiring bacterium Arthrobacter flavescens JG-9. Schizokinen production by Anabaena increased in low-iron media and was stimulated approximately five-fold media containing one millimolar citric acid. Growth of Anabaena under nitrogen-fixing conditions reduced extracellular schizokinen concentrations 3-4 fold, in late growth phase, compared to cells grown on nitrate. Cells grown in ammonium-containing medium yielded intermediate concentrations of schizokinen. The Csaky assay, which is …

A Study To Determine The Relationship Between Interest As Measured By A Student Interest Inventory And Recreational Nonfiction Books Checked Out Of The Library Media Center By Intermediate Grade Students At Sunnyside Elementary School, North Clackamas School District Number 12, Clackamas, Oregon, Larry Charles Leedy

Dissertations and Theses

The purpose of this study was to determine if a correlation existed between the selection of recreational nonfiction books from a school library media center by elementary school students in grades four through six and the measured interest, as generated by the Student Interest Inventory, of the students. Data for this study was collected during the period September, 1982 and April, 1983 at Sunnyside Elementary School, North Clackamas School District Number 12, Clackamas, Oregon. The raw data for the measured interest and recreational nonfiction books checked out were arranged by Dewey Decimal Classification tens. By using the Pearson product-moment correlation …

Trouble In River City: An Analysis Of An Urban Vice Probe, Joseph S. Uris

Dissertations and Theses

This dissertation is an historical case study of a highly publicized investigation of vice and official corruption which took place in Portland, Oregon from 1954 to 1958. Three major relevant areas of social science literature are reviewed. These are: historical material on American reform and corruption, criminology and political science. This literature suggests both the ubiquity and usefulness of vice and corruption in the urban situation.

A set of propositions regarding vice, corruption and reform was developed from these works. These propositions were then examined in terms of the vice probe and political situation in Portland, Oregon.

The triangulation method …

Electromagnetic Modes Of An Inhomogeneous Sphere, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

In many cases the electromagnetic modes of a sphere can be obtained exactly. Special simplifications occur when the conductivity, complex permittivity, and complex permeability vary only in the radial direction, and static and time dependent examples are discussed. With quadratic or Coulomblike permittivity variations, the wave functions resemble the quantum mechanical harmonic oscillator or hydrogen atom wave functions, and similar angular momentum operators are obtained.
