Geochemistry And Petrology Of The Cold Springs Breccia Formation, Wichita Mountains, Oklahoma, Dana Marie Vidrine

Masters Theses

"In the Wichita province of southwestern Oklahoma the Cold Springs Breccia Formation, exposed in a 15 km² area in Kiowa County, is characterized by blocks and pillows of microdiorite surrounded by pink granite. Intimately associated with this mixed zone are sill-like bodies of intermediate rocks, granodiorites and tonalites. The intermediate rocks have been interpreted as hybrids produced by assimilation of microdiorite by granitic magma, and the mixed zone has been interpreted as an intrusion breccia formed at the margins of the hybrid sills.

Major, minor and trace element data have been obtained on a suite of granites, intermediates, and …

Mineralogy And Chemistry Of The Tuff On Pritchards Station, East-Central Nevada, Stanley Christopher Hatfield

Masters Theses

"The Tuff of Pritchards Station in east-central Nevada is a little-known ash-flow tuff of limited areal extent. A detailed study of this tuff was conducted to determine if it is a distinctive unit which can be correlated from one locality to another.

Mineralogical and chemical data indicate that the Tuff of Pritchards Station displays significant lateral variability. Lateral variations in mineralogy include changes in total crystal content and the amount and grain size of individual minerals present over the area studied. Chemically, the tuff is a quartz latite to rhyodacite in composition. However, certain elements, most noteably titanium, show considerable …

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 …

Revision Of The Argenta-Oreana Faculty Handbook, Grades K-8, Ralph J. Lutz Jr.

Masters Theses

The development of a faculty handbook for the Argenta-Oreana School District grades K-8 was the subject of this field study. A faculty handbook had been issued previously, but it was outdated, lacking in detail, and had not been distributed for almost ten years. The high school had a recently revised faculty handbook, but the distinct differences between the high school and the lower grades would not permit the use of the same handbook by all teachers in the district.

The creation of this handbook was brought about mainly to answer the numerous questions the faculty had about board policies, grading, …

Dreamworlds And The Art Of Illustration, Donna Crotchett

Masters Theses

While I was growing up, illustrations made deep impressions upon me. An illustration is a picture that explains and adds interest to the written part of a printed work such as a book. Often overlooked by others, for various reasons, this means of communication played a significant part in my life and art.

The history of illustration is a history of men and women, serious artists, who have produced an enormous amount of high-quality work. Many of their illustrations had their origins in fine art such as early religious painting and mythological themes. A large number of fine artists have …

Noncompetitive Effects Of Morning Glory On Growth Of Soybeans, D. R. La Bonte

Masters Theses

Competitive effects of weed infestations in soybean fields can severely reduce yields. Noncompetitive factors (allelopathy) may also be involved. Soybeans (Glycine max (L.) Merrill, Asgrow A 3127 mid group 3) show a marked reduction in growth due to root exudation, leaf leachate and total plant extracts from white-flowered morning glory (Ipomoea lacunosa L.).

Analysis Of The Surface Polysaccharides Of R. Trifolii Su843 And Its Sym Plasmid Alterated Mutants, Jauh-Lin Duh

Masters Theses

The Rhizobium trifolii polysaccharides from SU843 and mutants--HC843(pBR1AN), HC843, 8002--in which the sym plasmid is replaced, absent, or mutated by transposon Tn5 were isolated. The surface polysaccharides of genetically altered mutants were compared quantitatively and qualitatively with one another and with the parent strain. The interpretation of these results is discussed in relation to the function of Rhizobium surface polysaccharides in the symbiotic process. The symbiotic ability of SU843 and mutant strains is as follows: (a) SU843, nod⁺, fix⁺; (b) mutant 8002, roa⁺ (still attaches to root hair), hac^-, nod^-; (c) …

Raw Water Quality In The New Charleston, Illinois Pump Storage Reservoir, Kevin G. Lookis

Masters Theses

Charleston, Illinois, a city located in east-central Illinois, recently implemented a new concept in a raw water system. Due to storage capacity-sedimentation problems in the old Lake Charleston-Embarras River raw water supply, the Charleston Pump Storage Reservoir was constructed. The new system involved building a dike separating the Lake Charleston impoundment from the Embarras River. Water to increase the storage capacity of the reservoir can now be selectively pumped into the impoundment from the river.

Raw water quality in the reservoir was monitored on a weekly basis for a full year from August, 1981 to August, 1982. The levels of …

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 …

Observed Changes In The Largemouth Bass Population Since Construction Of A New Pump Storage Reservoir At Charleston, Illinois, Lawrence B. Durham

Masters Theses

Lake Charleston, Illinois was electrofished to determine the status of the largemouth bass (Micropterus salmoides, Lacepede) population after its reconstruction into a pump storage reservoir. The changes observed were an increased rate of growth of the initial year class, increased average growth increment of older bass, and a more abundant bass population. Factors which may have influenced increased growth were decreased turbidity, alkalinity, and increased water level. There is a possibility the increase in water level led to an increase in terrestrial invertebrates as a food source, and increased spawning substrate and cover due to submerged terrestrial vegetation. …

Residual Phytotoxicity Of Mon-097 In Sludge Enriched Soils, Jennifer A. Woods

Masters Theses

Aerobically and anaerobically digested sludges were added to soil at concentrations of 0, 1, 5, and 10% (v/v). Dry weights of Avena sativa var. Noble plants, harvested 28 days after planting, were greater with increased sludge concentrations. Plant dry weights were consistently greater with aerobically than with anaerobically digested sludge. MON-097, an acetanilide herbicide, was applied to these soil/sludge mixtures at concentrations of 0, 0.5, 1, 2, 4, 8, 16 and 32 ppm. Residual phytotoxicity of MON-097 was not significantly affected by sludge concentration. These results suggest that increased concentrations of sludge in the soil do not contribute to detoxification …

Sintering was conducted at temperatures between 695° and 925°C for isothermal dilatometric shrinkage measurements for time intervals of 6000 seconds or less. Weight loss, shrinkage, density and porosity measurements were conducted on samples isothermally sintered between 690° …

Analyzing And Predicting Natural Circulation In A Snupps's Pwr Using "Retran-01", Roger Lee Boyer

Masters Theses

"The purpose of this project is to predict the natural circulation start-up test for the Standardized Nuclear Unit Power Plant System (SNUPPS). In order to make this prediction, a best-estimate, thermal-hydraulic computer code called RETRAN-01 is used.

The start-up test procedures require the simultaneous tripping of all four reactor coolant pumps (RCPs). Natural circulation is confirmed when the three test acceptance criteria have been met. Since this transient is symmetrical, a one-loop approximation of the Nuclear Steam Supply System (NSSS) is normally considered adequate in the nuclear industry. However, there is a concern over how to model the four actual …

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 …

Christianity And Delinquency: A Study Of Religiosity And Delinquency Involvement, Brenda T. King

Masters Theses

Much of the previous research on the relationship between religiosity and juvenile delinquency suggests that religiosity does not deter its adherents from moving toward anti-social behavior. Using a quite narrow definition of Christian, this conclusion was tested. Three questions were posed: (1) Does knowledge of religious status aid in predicting delinquency?: (2) Do Christians engage in less delinquency?; and (3) Do Christians with higher levels of religious commitment engage in less delinquency? The answer to each question is "No." There is very little difference between Christian and non-Christian delinquency patterns. The only significant difference uncovered was with life time delinquency …

The Effects Of Behaviorally Anchored Rating Scales As Antecedent And Consequent Stimuli Upon Instructional Behaviors In A Special Education Setting, Dennis L. Van Hartesvelt

Masters Theses

The present study was an attempt to determine the effects of the Behaviorally Anchored Rating Scale (BARS) upong three distinct instructional behaviors when presented before instructional sessions and when presented after instructional sessions. A multiple baseline design across behaviors was used with four subjects with a reversal element used with one of those subjects. A slight positive effect of BARS presentation upon instructional behaviors occurred. No significant differences were observed between preinstructional and postinstructional BARS presentation. The relevance of the present study is explored in relation to previous BARS studies, along with the implications of the present study.
