Microencapsulation As An Alternative To Emulsification For Preparing As A For Use In Papermaking, William J. Corriveau

Masters Theses

The sizing chemical ASA is emulsified to make i t compatible with the papermaking process. Unfortunately, emulsified ASA is chemically reactive with water at the elevated temperatures found in papermaking systems. As an alternative, encapsulated ASA was made and investigated for its stability towards water at elevated temperatures.

A handsheet procedure was developed to analyze emulsified and encapsulated ASA. It was concluded that the procedure gave statistically reproducible results. Investigations with the procedure revealed important variables concerning the laboratory and m ill application of ASA. Evidence indicated that retention of ASA was critical to sizing development.

One County's Experience With Community Corrections: An Assessment Of The Harm, Charles C. Crider

Masters Theses

Most correctional systems include pre-parole community placements. This study followed 114 inmates released to halfway house placement in one Michigan county over six years to determine the harm these inmates inflicted on the host community through new crime during halfway house placement and for three years following parole. Their criminal behavior was compared to statistical expectancies of criminal behavior for similar risk parolees. In a second analysis, the volume and seriousness of their criminal behavior was compared with non-comparable parolee controls. In both analyses, the extent and seriousness of crime by experimentals were comparable to that of controls. Criminal activity …

Synthesis Of Pyridine Nucleosides By Cycloaddition Reactions And Synthesis And Condensation Reactions Of 4-Aryl-2-Oxytetronimides, Glenn L. Heise

Masters Theses

Experiment 1: The reaction of various glutaconaldehyde salts (Na⁺ or K⁺) with glycosyl isothiocyanates has resulted in the formation of a novel class of compounds. Relatively mild conditions were utilized for the synthesis which occurs in four steps, and in good yield, starting from glucpseptentaacetate. These reactions were found to be regiospecific.

A Gravity Investigation Of Mountain Flank Thrusting And Normal Faulting, Madison And Tobacco Root Ranges, Montana, Stephen Thomas Wigger

Masters Theses

Gravity modeling of west-dipping, Laramide mountain flank thrusts which involve Archean metamorphic rocks in the western Tobacco Root and northern Madison Ranges supports the idea that these thrusts are gently dipping.

The thrusts provided a favorable location for normal faulting during Neogene extension. The Neogene faults on the eastern portions of the Madison and Jefferson Basins are interpreted to be listric, and merge with the Laramide thrusts. Basin development occurred along a series of such faults, which dropped hanging wall blocks of the thrust sheets to progressively greater depths. The maximum depth of the Madison basin, near Ennis, was found …

The Wiedergeburt In The Religion Of The Zoarites, Elizabeth Siber White

Masters Theses

In 1817 a little-known group of German Separatists fled religious persecution in Wurttemberg and took up residence in America. Eventually known as the Zoarites, they founded a religious commune in the northeastern Ohio wilderness in 1819, which they called Zoar, and continued to live the common life there until 1898, at which time they voted to disband.

What sort of religious beliefs led them to endure persecution in Germany and then to establish a religious commune in Ohio? This study was undertaken in part to answer just such questions. Relying primarily on the unpublished, largely untranslated discourses of J. M. …

The Trend In Canopy Composition In A Young Mesic Forest, Zhenchang Li

Masters Theses

Brewer Woods, a young disturbed mesic sugar maple-beech (Acer saccharum-Fagus grandifolia) forest in Kalamazoo Co., Michigan, was investigated by point-quarter and transition matrix methods. The results indicate that this forest is dominated by sugar maple in both canopy and understory composition. Beech is the second most important species. Fourteen species were found as canopy trees or replacements. The hypothesis that a young forest is more diverse than comparable climax forests such as Warren Woods and Hueston Woods was supported. Its successional trend is that sugar maple will become more abundant at the expense of the other species. Beech is a …

The Effect Of Word Abbreviation On Decoding Speed And Accuracy, Frances Piccione

Masters Theses

An experiment was conducted to verify the existence and determine the magnitude of the human response latency differential between words and their abbreviations in a decoding task. Forty-eight Naval Officer Candidates learned a set of abbreviations obtained from operational aircraft cockpits. Abbreviations and corresponding words were divided into easy and hard difficulty levels. Subjects responded by saying the correct whole-word for both stimulus types. Response times measured by a voice key revealed a mean of 0.534 seconds for words and 0.662 seconds for abbreviations. An analysis of variance produced significant main effects (p < .05) for stimulus types and difficulty levels; the interaction effect was not significant. Also, t-tests for correlated scores revealed significant differences (p < .05) between difficulty levels within stimulus types.

A Seismic Study Of An Impact Feature In Cass County, Michigan, Mancheol Suh

Masters Theses

A geophysical investigation, including a seismic study, of the subsurface structure of the Calvin-28 oil field, Cass County, Michigan, indicates that the structure's origin may be related to an impact event. The structural closures in the time structure maps and drilling results both show a central uplift. The fault system in the Trempealeau Formation shows a structure similar to other proven astroblemes. Undisturbed layers just beneath the central uplift also provide evidence of an impact structure. The result of mathematical modeling of the central uplift under the assumption that the structure is an impact structure corresponds well with the drilling …

The Pauli Operator Correction In The Effective Λn Interaction, Jaleh Owliaei

Masters Theses

Hypernuclear structure calculations performed for ⁶_ΛLi, ⁷_ΛLi, and ¹⁶_Λ0 have reproduced the 1_Λ=1 levels inferred from the recent (k, Π) reactions. However the 1_Λ=0, groundstate of ¹⁶_Λ0 is overbound by 6 MeV in these calculations, indicating a density dependence in the effective ΛN interaction in the interior of the heavier system. In this work corrections to the ¹⁶_Λ0 effective interaction are introduced in terms of a Brueckner-Goldstone G-matrix with a modified Pauli operator. The G-matrix of ¹⁶_Λ0 derived from that of ⁶_ΛLi …

An Investigation Of The Effectiveness Of Study Aid Formats, Mary Anne Saint

Masters Theses

The effectiveness of matrix organizational format versus outline organizational format versus self-structured study notes was tested with high school subjects. Contrary to predictions, results of a multiple choice and essay question posttest revealed a nonsignificant study aid effect, F (2, 53) = 1.17, p > .05. An interaction between passage order and subject sex was significant, F (2, 53) = 4.68, p < .05. An analysis of recall, application and analysis levels of learning again revealed a nonsignificant study aid effect, F (2, 68) = 1.53, p > .05. A difference among recall, application and analysis posttest scores was significant, F (2, 4) = 93.25, p < .05. It was noted that the mean of the Matrix Group was somewhat greater than other groups across all five measures. The probability of one of three groups outscoring other groups across five analyses would result in a chance level of occurrence of .0039. It is speculated that additional experimentation will demonstrate a significant difference in the effectiveness of study aid formats.

Automated Evaluation Of Reservoir Parameters Applying Pressure Transient Theory, Steven Robert Homoky

Masters Theses

"This study presents an investigation to automatically evaluate reservoir parameters using pressure transient theory. Methods will be introduced to numerically fit the well test data in the real (time) domain (specifically the pressure change as a function of test time). The numerical fit and known fluid, rock and well properties will be used to evaluate the dimensionless storage coefficient. The theoretical dimensionless pressure (being a function of skin factor, permeability, and dimensionless storage coefficient) is obtained by Laplace Inversion. The ability to evaluate the dimensionless storage coefficient thus reduces the parameters of the pressure equation by one. Varying the skin …

An Evaluation Of Magnetic Field Shielding And Cross Talk For Various Cable Configurations, Amir Hossein Nafar

Masters Theses

"The effect of shield grounding on magnetic field coupling in coaxial and twisted pair cables, was studied for various positions of the ground connection at 50 KHz. For the case of only one end of shield grounded the attenuation was about 60 dB. Furthermore, the effect of frequency from 50-500 KHz was considered on three cases. Thus it was concluded that attenuation increases as frequency increases. A combined experimental and analytical investigation was also conducted to characterize the mechanism of cross talk between wires of ribbon cable and traces on printed circuit boards. Inductive and capacitive coupling were studied in …

Industrial Simulation With Animation, Edward T. Hammerand

Masters Theses

"This thesis examines and evaluates the new simulation language PCModel.
