Vocal Pitch Range And Habitual Pitch Level: The Study Of Normal College Age Speakers, Patricia Jo Huss

Masters Theses

The purpose of this study was to compare the relationship between the habitual speaking pitch levels and the total pitch ranges.of 15 male and 15 female normal young adults and to compare these relationships to those which have been reported previously for male and female superior speakers. The difference between normal male and normal female speakers was significant, as was the difference between normal male speakers and superior male speakers. The difference between normal female speakers and superior female speakers was non-significant.

Non-Equilibrium L-Shell Effects On K-Shell X Rays For 20-54 Mev S+C Collisions, Donald Solon Shippy

Masters Theses

Projectile K x-ray yields have been measured as a function of target thickness (2.0-150 μg/ cm²⁾ for 20-54 MeV S^q+ ions incident on this carbon foils using the WMU EN tandem Van de Graaff accelerator. The measured K x-ray yields were fond to increase for thicknesses < 15 μg/cm² and decease for thicknesses > 15 μg/cm² . The increasing yield is attributed to L-Shell non-equilibrium as the ion traverses the foil, while the decreasing yield is attributed to K-shell non-equilibrium. Analysis of the data was performed by modifying the "two-component" model of Betz et al. to include the effect of …

Environment Of Deposition Of The A-1 Carbonate, Salina Group, Michigan Basin, Barbara June Leonard

Masters Theses

The lower Salina Group of the Michigan Basin is composed of a cyclic succession of carbonate and evaporite units. The lowermost Salina unit is the A-1 unit which consists of a lower A-1 evaporite and an upper A-1 carbonate. The A-1 unit is underlain by Niagara Group carbonates. The transition from Niagaran carbonates to A-1 evaporite to A-1 carbonate has not been thoroughly understood and previous models have not satisfied some of the evidence. This paper sets forth the hypothesis that the A-1 carbonate was deposited in a non-marine lake environment rather than an isolated marine environment. Findings supporting this …

Identifying Jungial Personality Type By The Instrument Of Self-Report, Charles Clay Livingston

Masters Theses

This paper examines the instrument of self-report and its use in identifying and measuring the elements of the personality as defined by C. G. Jung. Jung's theory of personality is briefly explained, and self-report as a general instrument of personality assessment is critically examined. Selected research on the construction and use of self-report tests is reviewed and critically evaluated. The author asserts that the bipolar assumption that is often implicit in the construction of test items is not representative of the personality as Jung portrayed it. The author suggests revisions in the construction of test items and a scoring gradient …

A Microprocessor Controlled Pulsed Hollow Cathode Lamp For An Atomic Absorption Spectrometer, James B. Schilling

Masters Theses

A Jarrell-Ash Atomic Absorption/Flame Emission 82-360 Spectrometer was interfaced to a Heathkit ETA-3400 microprocessor. The microprocessor is used to pulse the hollow cathode lamp from a "steady" current to a "peak " current during the opening of the chopper. The current from the photomultiplier-tube is converted to a proportional voltage which is supplied to a sample-and-hold circuit. A successive approximation routine is used to convert the voltage to a representative digital value. Digital values are obtained for the "blank" and "sample" and are used to calculate percent absorption values. The system can also be used to obtain emission values.

The Creationist Movement: Science, Religion And Ideology, George M. Bevins

Masters Theses

A sample of literature produced by participants in the "creationist movement" is examined in an effort to delineate the ideology of the movement. This ideology is seen as a repertoire of images of science, evolution and society which is used by creationists in their efforts to propagate their movement. Based on this literature, an "ideological substructure of belief" within the creationist movement is described, consisting of their belief in a created normative order in the world and of their fear that this order is breaking down. It is argued that the various particular aspects of the creationists' social ideology, their …

Sedimentation Rate Of Salt Determined By Micrometeorite Analysis, James Matthew Barnett

Masters Theses

The sedimentation rate of the A-l Evaporite of Michigan was determined by analysis of micrometeorites found as inclusions in the halite deposit. The samples were obtained from the Dow Chemical Company salt well number eight. The residue from the dissolved salt was magnetically separated and later analyzed by Particle Induced X-ray Emission (PIXE), X-ray diffraction , and microprobe techniques. The amount of extraterrestrial material was determined from the quantity of nickel present.

A sedimentation rate of .01 to .4 centimeters per year was calculated for the salt based on a constant influx rate of meteoritic material of 1 x 10 …

The Geology And Geochemistry Of The Summit Creek Molybdenum Prospect, Custer County, Idaho, Thomas Murray Hanna

Masters Theses

The Summit Creek stock, a molybdenum prospect located in the Pioneer Mountains of central Idaho, is a 46.7 m.y. old medium grained, slightly porphyritic quartz monzonite, which has intruded the late Ordovician Phi Kappa formation. Trend surface analysis shows that the stock is the product of one intrusive event. Pervasive mineral alteration usually associated with such porphyry (stockwork) molybdenum deposits is not present in this pluton, and the alteration that is present is confined to local faults and fractures.

Geochemical and petrographic evidence suggest that the pluton is a felsic differentiate from a melt which originated at a depth of …

Electrical Resistivity Survey Near The "Kl" Avenue Landfill, Kalamazoo County, Michigan, David W. Hall

Masters Theses

The KL Avenue Landfill near Kalamazoo, Michigan has recently become an area of ground water contamination. As of April, 1979, the landfill was closed due to contaminated wells to the west. This area was chosen to study because preliminary electrical resistivity surveys indicated that the approximate areal extent and depth of the contamination may be located without the additional cost of drilling wells. It is the intent of this study to use the Schlumberger Vertical Electrical Sounding method to construct a hydrogeologic model for this area.

This study is a rather critical test of the Schlumberger VES method in a …

Lithofacies Analysis Of The Roubidoux Formation, South Central Missouri, Michael William Harbaugh

Masters Theses

"Lithologic and thickness data of the Lower Ordovician rocks of the Roubidoux Formation, south central Missouri, were interpreted from sample logs. Maps included are based on structure, thickness and lateral and vertical lithologic variability. Sand distribution in the Roubidoux is represented by a "sand percentage" map, a "sand isolith" map, and a "tripartite sand distribution" map. The Roubidoux Formation consists of a sequence of dolomite, sandy dolomite, sand and chert. It is believed that the Roubidoux was deposited on a stable marine platform receiving a supply of elastics from the north and northeast. The sands were deposited by longshore or …

A Theoretical And Experimental Investigation Of Single Phase Flow Through A Small Centrifugal Pump In Three Quadrants Of Operation, Lee Charles Cadwallader

Masters Theses

"The operating characteristics of a conventional centrifugal pump have been investigated, both theoretically and experimentally, in three modes of operation with single phase liquid water at atmospheric pressure and room temperature.

Simple one-dimensional theory has been used to evaluate the theoretical pump performance, and these evaluations are compared to actual experimental data. The actual data shows the degradation effects of flow friction and shock losses that the theory does not take into account. The comparison of the curves illustrates these differences.

The data obtained compares well to and reinforces data from experiments found in the literature review.

Based on the …

Investigation Of Important Surface Characteristics Of A Finned Tube Heat Exchanger, Bobby Dale Stafford

Masters Theses

"Surface characteristics of a finned tube heat exchanger were examined to help predict the contact geometry between metal surfaces. These characteristics were the surface roughness and waviness and the material hardness. A scanning electron microscope was used to observe the surface topography of the fins as well as examining the contact between the aluminum fin and the copper tube.

Comparisons of the surface roughness were then made between heat exchangers having different fin numbers (20, 14, and 6) with the result that as the fin number decreased, the roughness also decreased. For a given fin number, it was discovered that …

A Technique For Obtaining Very Efficient Dynamical Equations For On-Line Computation Of Joint Forces Of Robotic Mechanisms, Dennis A. Dohogne

Masters Theses

"In order to increase the operational speed and positional accuracy of robotic mechanisms, on-line force control has been proposed. Because of the complexity of exact dynamical formulations, real-time computation of joint forces may be too slow.

Since force control is accomplished with a dedicated computer, unique, dedicated sets of force equations are justified. An efficient force computation technique based on the algebraic expansion and recombination of exact dynamics formulations is presented. Developments of the robotics matrix notation and of a Lagrangian dynamics formulation are also presented. A generalized three link manipulator model is used to compare the computational complexities of …

The Perception Of Coincidence: Artistic Symmetry In The "Wandering Rocks" Episode Of James Joyce's Ulysses, James A. Scruton

Masters Theses

James Joyce's Ulysses, the most influential novel of the twentieth century, has often been criticized for its fragmentation and complexity. Impenetrable to some readers, misunderstood by others, Ulysses bears within its eighteen episodes a symmetry of subject and form that at once clarifies and multiplies the meanings to be found there. Richard Ellmann calls Joyce's theory of art "the perception of coincidence," a theory best exemplified by "Wandering Rocks," the central episode of Ulysses. The use of "symmetrical coincidence" in ''Wandering Rocks" can be seen in two ways: 1)the internal structure of the episode, and 2)its location among …
