Internal Rotation Effects And Nuclear Hyperfine Structure In The Microwave Spectrum Of Propyne-Hf, Roger E. Bumgarner

Masters Theses

The microwave spectrum of the weakly bound propyne-HF/DF complex in the region between 6 and 16 GHz was analyzed. The spectrum was characteristic of a distorted T-shaped asymmetric top exhibiting torsional splitting caused by a low barrier to internal rotation of the methyl top relative to the propyne-HF frame. Deuterium substitution of HF confirms that the acid proton of HF is located between the F atom and the propyne triple bond. The spectroscopic constants given below are consistent with the fluorine atom being displaced toward the methyl group from a line perpendicular to and bisecting the propyne triple bond, suggesting …

A review is given for the case of very large principal quantum numbers N; then the binary collision method is detailed for low transitions (N ≤ 6) where the computed values are in very good agreement with the experimental results obtained by Krebs and Schearer.¹ This method breaks down at larger N. Next, a modification …

Freedom At Midday: Elements Of Existentialism In The Works Of Ambrose Bierce, Sharon A. Winn

Masters Theses

Ambrose Bierce exhibited a number of elements of existential thinking both in his life and in his writing. But he was ambivalent about his philosophical stance, and it is difficult to know whether he was the utter pessimist he has been called, or whether his attitude toward the universe admitted a certain optimism.

Much of Bierce's thought parallels modern existentialism, which has three main tenets: a belief that there is no God and the universe is, therefore, irrational; a descent into despair; and a choice of life or death.

Bierce insisted that the universe is irrational, and he repeatedly discussed …

Four of five teachers showed rapid comprehension of classroom programs when the use of diagramming was compared to written narratives. College students described antecedent events present in familiar educational systems at a higher percentage of accuracy and total information presented almost doubled when diagrams were utilized. Training public school students in drawing state diagrams was initially successful. This …

Increasing The Work Rates Of Visually-Impaired, Mentally Retarded Adults Through The Treatment And Prevention Of Overselectivity (Overshadowing) And Masking, John Schwade

Masters Theses

In Experiment 1, three legally-blind, mentally retarded adults were given 10 to 12 applications of discrimination training between pairs of sequential compound stimuli with immediate tactile and delayed (3- 3.5 sec) visual elements. Sorting responses were brought under the control of these stimuli. In 29 of 33 applications, discrimination training resulted in reduced sorting rates concommittant to overselectivity (overshadowing), such that stimulus control was acquired by only delayed visual elements. Single-stimulus discrimination training (SSDT) between the previously-overshadowed immediate tactile elements produced expression of stimulus control by those elements of compound stimuli in 5 of 6 cases. SSDT with novel stimuli …

Religious Education In South Australian Public Schools, David I. Kumnick

Masters Theses

In 1972 the Education Act of South Australia was revised so as to make compulsory the teaching of religion in public schools. The major church leaders in South Australia held pro-Christian views about the form the new religious education should assume. Certain factors, most obviously a vigorous humanist campaign conducted during 1974 and 1975, wrought a dramatically different religious education syllabus. Convinced that the Christian religion was not being accorded its proper place, the church leaders finally lodged a united complaint with the Education Department of South Australia in 1979. The problem confronting all concerned South Australian Christians in 1982 …

Temporal Pattern Of Gluconeogenesis In Diabetic And Non-Diabetic Chinese Hamsters, John P. Ofenstein

Masters Theses

Gluconeogenesis is a normal physiological response of an individual to low blood glucose levels by which proteins are utilized in order to synthesize new glucose. Gluconeogenic rates in diabetic and normal Chinese hamsters were measured, on four different occasions over a 24 hour period, by injecting a radio-labelled precursor (¹⁴C-lactate) into the animals. Then blood was tested for incorporation of the label into glucose. In the fed state, gluconeogenesis shows a circadian change in nondiabetic hamsters as well as in diabetic hamsters, with the diabetic hamsters showing a significantly greater gluconeogenic rate than the non-diabetic hamsters for every …

A Comparison Of The Effects Of Two Different Respiratory Valves On Maximal Oxygen Uptake And Heart Rate Response Of Selected Distance Runners, Jeffry Phillip Morgan

Masters Theses

This study compared selected cardiorespiratory responses obtained from two different respiratory valves, the Modified Otis-McKerrow and the Speak Easy, a mask-type valve, during maximal graded exercise testing of eleven distance runners. The results indicated that both maximal oxygen uptake and minute ventilation were significantly different. Values for maximal VO₂ and V_E were lower with the Speak Easy by 24 and 19 percent, respectively. Further analysis revealed that those differences were significant at submaximal levels as well. The trends in those responses show that the differences increase with increasing workload. However, maximal and submaximal heart rates were not significantly …

Intelligibility Of Speech Produced With An Artificial Larynx At Various Frequencies, Sandra Arlene Merritt

Masters Theses

Word intelligibility scores of 21 listeners were used to test the hypothesis that speech intelligibility will vary systematically across speakers and fundamental frequency of electrolarynx vibration.

Twenty-one listeners transcribed audio recorded lists of CVC utterances produced with an electrolarynx by 3 speakers at each of five fundamental frequencies.

Comparative analysis of scores across frequencies and speakers were discussed in terms of:

a) source transmission characteristics of "electrolaryngeal" speech, b) implications for diagnosis/therapeusis of alaryngeal speakers.

Results indicated that intelligibility scores were significantly different between speakers and between frequencies within speakers. Maximum intelligibility scores were more highly correlated with certain frequencies …
