Direct Current-Excited Cw Co² Metal Waveguide Laser, Fahad S. Al-Mashaabi, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

A novel design for a dc-excited cw CO₂ metal waveguide laser has been developed in which a slotted hollow cathode also doubles as a metal waveguide for the cavity modes. This design has been implemented in a compact structure that produces over 1 W of cw 10.6-µm radiation. The discharge characteristics, laser gain, and laser output have been studied as functions of various discharge parameters. The advantages of the transverse discharge of the slotted hollow cathode geometry include low voltage, positive impedance, rugged structure, and high optical gain. Overall efficiency is comparable with that of conventional longitudinal CO² lasers. The …

Decay Of Molecules At Corrugated Thin Metal Films, P.T. Leung, Young Sik Kim, Thomas F. George

Physics Faculty Publications and Presentations

The problem of the decay rate for molecules at corrugated thin metal films is considered theoretically via a classical phenomenological approach by generalization of a previous theory for a single rough surface. In particular, numerical results are worked out in detail for grating films with various possible arrangements of the two grating surfaces, and for both cases with a supported and a free-standing film. Effects due to cross coupling into the long- and short-range surface plasmons are observed, and correlations to recent experiments performed by Gruhlke, Holland, and Hall are made. It is suggested that fluorescence experiments with pulsed-laser excitations …

Disability Rights Mandates: Federal And State Compliance With Employment Protection And Architectural Barrier Removal, Stephen Percy, United States Advisory Commission On Intergovernmental Relations

Office of the President Publications and Presentations

The findings of this study indicate that the existence of national mandates does not necessarily eliminate the need for citizen groups to be attentive to state capitols and city halls. Ironically, one factor in the rise of regulatory federalism has been the desire of interest groups to concentrate their resources on one government, namely, the national government, rather than 50 different state governments. Yet, success in the national arena is often only partial, and sometimes only largely symbolic. It is the implementation of national rules that takes one back to states and localities.

The findings of this study also suggest …

The Effects Of Bandwidth Limiting Tuning Elements On A Synchronously Pumped Mode-Locked Dye Laser, Bahram Zandi

Dissertations and Theses

In this study an improved description of the bandwidth limiting tuning filters has been introduced into a semiclassical model for a synchronously pumped mode-locked dye laser system. This model is an improvement over the traditional rate equation approach since it has detailed representations of the energy levels, rotational distribution, and coherence effects. The new set of equations has been solved numerically using the best available values for the various parameters, and autocorrelations have been computed for a range of different length detuning and bandwidth limiting elements. In the experiments, an acousto-optically mode-locked argon ion laser is used to synchronously pump …

An Analysis Of The Relationship Between Learning Style Perceptual Preferences And Attitudes Toward Computer-Assisted Instruction, Mary Brambilla Mcfarland

Dissertations and Theses

The purpose of this investigation was to identify the perceptual learning style preferences of nursing students and to examine the relationship, if any, among students whose learning style perceptual preferences were identified as being auditory, tactile or visual and their attitudes toward the use of computer-assisted instruction (CAI) in the areas of comfort, creativity and function. The relationships between nursing students' perceptual learning style preferences and the following were also examined: (a) the amount of time they spent using the computer program, Cardiac Exam Bingo; (b) whether the use of the computer program added to their learning the content about …

The Use Of Efficient Information Systems For Information Acquisition By The Hearing Impaired: A Case Study, William L. Nicolay

Dissertations and Theses

This paper presents an exploratory case study focusing on the acquisition of information, through technologically efficient systems, by the hearing impaired. The multiple-case study was conducted during one school year with seven students participating.

While a central question and propositions derived from that question guide the data collection and analysis, this is a hypothesis-building study. The purpose of the study was to generate questions to focus further research of a descriptive or explanatory format.

One question, and the propositions generated by it, dominated this research: How do efficient acquisition systems in the classroom effect academic and social behavior, independent activities, …

Teacher Perceptions Of Evaluation As An Agent For Teacher Growth And Improvement Of Instruction, Beverly Ann Hobson

Dissertations and Theses

The purpose of this study was to measure the perceptions of teachers regarding their most recent evaluation experience and to determine whether teachers perceive any significant relationships between attributes of teacher evaluation and its quality and impact on teacher growth. The study also considered whether there are significant differences between elementary and secondary teachers, as well as between classroom and nonclassroom teachers, in their perceptions of evaluation.

The suburban school district in this study serves approximately 22,000 students. The subjects included 402 elementary and secondary teachers who were randomly selected from 1,081 permanent teachers.

The Teacher Evaluation Profile (TEP) instrument …

Fluorinated [Beta]-Sultones As Precursors To Fluorinated Sulfonic Acids, And New Fluorosulfonyl Containing Monomers/Polymers, Javid Mohtasham

Dissertations and Theses

Sulfur trioxide (SO₃) adds to fluoroolefins of the form RCF=CF₂, (where R = F, SF₅, CF₃, CF₃OCF₂, CF₂=CF(CF₂)₂, CF₃(CF₂)₃O, CF₃O(CF₂)₂OCF₂, or CH₂ClCHClCH₂), yielding the fluorinated [beta]-sultones, RCFCF₂OSO₂. In the case of CF₃(CF₂)₃OCF=CF₂, a reverse addition occurs, giving the sultone, CF₃(CF₂)₃CF₂2OCFCF₂SO₂O. The fluoro [beta]-sultones are capable of undergoing different reactions, such as rearrangement, hydrolysis, esterification, and polymerization. These reactions, will result in the formation of compounds containing the fluorosulfonyl grouping (SO₂F); it is this group that yields the corresponding sulfonic acid upon base/acid treatment.

The addition of sodium bisulfite to CF₃CF= CF₂ and CF₃(CF₂)₄CF=CF₂ in the presence of (C₆H₅CO)₂O₂ and Na₂B₄O₇·10H₂O …

Commercial Activities And The Geography Of Movement In A West African Urban Market: A Study Of Market-Stall Traders In Onitsha With Implications For Transport Policy, Krys Chukwuma Ochia

Dissertations and Theses

The purpose of this study is to understand the non home-based travel behavior of urban market traders in Onitsha, Nigeria, where 58-70% of the labor force is engaged in trading.

Relevant trip-inducing variables--gender, location, a means of personal transportation, size of stall and, type of good sold--were selected to assist in theorizing about the travel behavior of traders. Using a systematic sampling methodology, 246 stalls were selected and the MLR model was applied in data analyses.

The results show that a typical stall is occupied by either one or two traders. There are three male traders for every female trader …

Analysis Of Ferredoxin And Flavodoxin In Anabaena And Trichodesmium Using Fast Protein Liquid Chromatography, Karen Lorraine Jones

Dissertations and Theses

Iron is an essential nutrient for growth of photosynthetic microorganisms such as cyanobacteria and algae. Iron is required for proteins involved in the important processes of carbon and nitrogen assimilation. Low concentrations of iron in cultures or natural waters can lead to iron limitation which affects many aspects of algal metabolism. In natural waters, iron limitation can have effects on the patterns and rates of primary productivity.

The cellular content of certain proteins can be affected by media iron concentrations. Methods have been used that assay components of the cell as an indirect measure of iron nutritional status. For example, …
