The Analysis Of The Deflection And Containment Of A Hot Plume By Side Draft Exhaust Hooding, Douglas H. Macgowan

Dissertations and Theses

A common industrial ventilation and pollution problem results when a thermally buoyant polluted plume of air must be exhausted away from a work area to allow achievement of air pollution standards. Generally, a close fitting canopy hood is one of the most effective means of exhaust containment; however, physical restrictions or the operation itself often prevent such an arrangement, and a hood located to the side of the operation is required. This arrangement requires the exhaust to bend and contain the vertically rising plume with a horizontal sweep of exhaust air across the surface of the operation.

A review of …

Series Of Drawings And Paintings, William Dyas Garnett

Dissertations and Theses

At the beginning or the program my work was strongly oriented toward the individual objects used in the paintings and lacked any cohesive means or unification. Collage was used as an attempt for unification but more was still needed. It was not until I let go or observed or preconceived images and allowed the image to develop from the free now or washes and lines that I was able to allow the picture to give ideas back to me. The pictures were now growing from themselves and from the ideas suggested to me, without having to force the image prior …

The Chromosome Constitutions Of A Hybrid Salmonid And Its Parental Types: Salmo Gairdneri And Salmo Clarki, Peter Bruce Valentine Jacky

Dissertations and Theses

A study was undertaken to investigate the application of tissue culture and histochemical banding techniques normally used in mammalian studies to fish cells and to examine the mechanisms of chromosome evolution and speciation in salmonids by comparing the chromosomes of the hybrid to those of the parental types. The application of banding techniques was generally unsuccessful in revealing bands, though quinacrine staining did reveal the presence of two fluorescent spots in the vicinity of the centromere. These were thought to be heterochromatic blocks, possibly related to the high incidence of centric fusion or fission in salmonids. Results of chromosome analysis …

Bayesian Inquiry: An Approach To The Use Of Experts, King G. Yee

Dissertations and Theses

Subjective information is a valuable resource; however, decisionmakers often ignore it because of difficulties in eliciting it from assessors. This thesis is on Bayesian inquiry and it presents an approach to eliciting subjective information from assessors. Based on the concepts of cascaded inference and Bayesian statistics, the approach is designed to reveal to the decision-maker the way in which the assessor considers his options and the reasons he has for selecting particular alternatives. Unlike previous works on cascaded inferences, the approach here focuses on incoherency. Specifically, it employs the use of additional information to revise and check the estimates. The …

The Design Of An Automatic Electronic Preanodizer, Armen C. Grossenbacher

Dissertations and Theses

The topic of this thesis is the design of an automatic preanodizer to be used to preadjust precision tantalum resistors by anodizing their surfaces. The purpose of the preanodizer is to generate a controllable voltage ramp to be applied to a set of tantalum resistors which are immersed in a suitable electrolyte. The slope and maximum value of the voltage ramp are set to produce the current required for proper anodization of the resistors. The rate of anodization determines the rate of change of the resistor value. This thesis covers the design of an electronic device to meet a set …

Clinical Application Of The Midi-Mult, Barbara Hendricks

Dissertations and Theses

The MMPI is used as a diagnostic tool in clinical settings. However, its length is a detriment. Various attempts have been made to develop shortened versions of the standard MMPI. One of the widely used short forms is Kincannon's Mini-Mult, but its validity scales are less accurate than the full MMPI.

Dean's Midi-Mult is a more recent short form of the MMPI designed to approximate more closely the scores on the validity scales and clinical scales of the standard MMPI.

Assessment Of Hearing Sensitivity By Use Of The Acoustic Reflex In The Geriatric Population, Donna Elvira Gilham

The Effect Of Natural Childbirth Classes On Anxiety In Pregnant Women, Kitty M. Wilkinson

Dissertations and Theses

A study was conducted to investigate the claim made by proponents of the natural childbirth method that attendance in the program results in a decrease of the anxiety commonly associated with pregnancy and delivery. Seventy-two pregnant women filled out the A-State and A-Trait forms of the STAI twice in their obstetricians' offices at points which approximated 6.5 and 8.5 months along in their pregnancies. Subjects who elected not to attend natural childbirth classes evidenced significantly higher state and trait scores as compared to those scores of subjects who did attend classes. Implications for dealing with these differences are discussed in …

A total of forty-five normal second, third, and fourth grade subjects were individually administered the Auditory Memory Test Battery (AMTB) which consisted of five tape-recorded tests of recall for digit sequences, unrelated word sequences, related word sequences, nonsense word sequences, and sentences. The subjects responded verbally to the randomly presented subtests. …

Listener Perception Of Fluent, Breathy, And Imprecisely Articulated Speech Of Stutterers, Diane Carol Campbell

Dissertations and Theses

Because communication involves both a sender of messages, each person could influence the other’s feelings about speaking and listening. The reactions of each member of this communication network will determine how communication will flow in the future. With an understanding of the feedback system between speakers and listeners, researchers have designed management programs which allow the speaker who stutters to develop a new pattern of speech which does not hinder his communication efforts. Fluency is the primary consideration, and normalcy of speech is second. One such program has been devised by Casteel (1974).

In Casteel’s stuttering management program a person …

Mary's River Kalapuyan: A Descriptive Phonology, Yvonne P. Hajda

Dissertations and Theses

The thesis is an attempt to apply procedures of descriptive linguistic analysis to a body of material phonetically transcribed by Leo J. Frachtenberg in the Mary's River dialect of the central Kalapuyan language. In 1913-14 Frachtenberg collected thirteen volumes of myth texts in Mary's River, twelve from William Hartless and one from Grace Wheeler; in addition, there were notes to the texts, three volumes of grammatical notes, and some ethnographic material. The phonetic transcription was carried out in the pre- phonemic tradition of recording everything the speaker said as accurately as possible. There was no attempt to elicit forms in …

Revolutions: A Comparative Study, Thomas E. Gill

Dissertations and Theses

The purpose of this thesis is to describe and then to compare common descriptive characteristics (uniformities) evident within three historical events: the Paris Commune of 1871, the Zapatista Movement of the Mexican Revolution between 1910 and 1919, and the Spartacist Rebellion of 1919. One such uniformity is the fact that all three are abortive social revolutions.

The Geology Of The Castle Rock Area, Grant, Harney And Malheur Counties, Oregon, John David Wood

Dissertations and Theses

The geology of the Castle Rock area aids in the understanding of Cenozoic volcanic stratigraphy and structures in an area where these volcanic rocks thin near the margins of the pre-Tertiary basement rocks and structural trends are overlapping. The Castle Rock area is unique in several aspects and is important in understanding and interpreting the geology in adjacent regions which have all been studied, at least on a regional basis. Intrusive ash-flow bodies of the Dinner Creek Ash-Flow Tuff, well-exposed sections of complexly interstratified volcanic rocks and well-exposed faults, and of high amount of erosional relief are features which make …

The Circulation Of Elites In Twentieth Century American History: The New Deal As Case Study, Diane Theresa Volk

Dissertations and Theses

Reviewing the scope and credibility of C. Wright Mills' provocative study, The Power Elite, for a seminar on U. S. in the Sixties prompted my interest in the validity of assessing the historical process by means of the elitist perspective. This coupled with my belief that the New Deal era ushered in a new chapter in the political history of the United States precipitated an investigation of the elitist perspective and how that perspective illuminated the conditions of historical change effected by the New Deal.

The Chemistry Of Chromium (Vi) And Chromium (V) Oxide Fluorides, Patrick Jay Green

Dissertations and Theses

New preparative routes to chromyl fluoride were sought. It was found that chlorine monofluoride reacts with chromium trioxide and chromyl chloride to produce chromyl fluoride. Attempts were made to define a mechanism for the reaction of ClF and Cr0₃ in light of by-products observed and previous investigations. Carbonyl fluoride and chromium trioxide react to form chromyl fluoride and carbon dioxide. A mechanism was also proposed for this reaction. Chromium trioxide with MoF₆ or WF₆ reacts to produce chromyl fluoride and the respective oxide tetrafluoride.
