A Hydrogeochemical Characterization Of A Glacial-Drift Aquifer System In Southwest Michigan, Patrick G. Barrese

Masters Theses

A hydrogeochemical investigation of the Schoolcraft Aquifer, an unconfined, glacial-drift aquifer located in southwest Michigan, was undertaken to focus on three topics: (1) the geochemical definition of recharge and discharge zones both vertically and laterally along projected flow paths, (2) the description of the carbonate and redox chemical systems, and (3) groundwater degradation associated with excessive nitrate, ammonium, and chloride concentrations.

The results of the study were inconclusive in defining recharge and discharge zones; however, iron and alkalinity concentrations were identified as possible indices for recharge and discharge conditions. The carbonate analysis indicated that the aquifer is saturated with respect …

Comparison Of Body Assessment Using Bioelectrical Impedance And Skinfold Measurements In The Critically Ill, Elizabeth Mae Gohlke

Masters Theses

This investigation compared two body fat assessment techniques, skinfold thicknesses and bioelectrical impedance, in an elderly population. Ten healthy adults and ten critically ill adults, aged 55-93 years, were tested. The body fat measurements were taken over a two-week period. Electrolyte levels, sodium and potassium, and hydration status were monitored. Intraclass reliability coefficients were calculated using a repeated measures analysis design (ANOVA). Bioelectrical impedance was not found to be a reliable method for estimating body composition in this study; reliability coefficients were R =.83, R =.98, R =.83, and R =.32 for healthy males, healthy females, critically ill males, and …

A Comparison Of Science And Mathematics Achievement, Attitudes, Curricular Experiences, And Career Interest Resulting From Magnet And Traditional High School Programs, Rozana Abdul Razak

Dissertations

The growth of specialized schools that emphasize science and mathematics has raised questions about their efficacy in improving performance in various parameters in mathematics and science. In this study, four different components were compared. A science and mathematics experiences questionnaire determined the type and extent of student experiences in science and mathematics during high school, and student interest in science and mathematics careers. The American College Testing Program (ACT) (ACT Registration) sub-scores assessed scholastic achievement, while the determination of student attitudes towards science used the Scientific Attitude Inventory (SAI) (Moore & Sutman, 1970).

Subjects in the study consisted of three …

Micellar Catalysis Of Hydrolysis Of Substituted Hydroxamic Acids With Perfluorooctanoic Acid, Zhongyuan He

Masters Theses

The work demonstrated the effects of differently located and substituted phenyl groups, as well as aliphatic groups in the hydroxamic acids, on micellar catalysis with perfluorooctanoic acid as the reactive counterion surfactant in aqueous acetonitrile solution.

Kinetic rate constant-surfactant concentration profiles for the decano-, 2,5-dimethylphenylaceto-, 4-isopropylphenylaceto-, 4-phenylbutano-, and 6-phenyl-hexanohydroxamic acids were examined and analysis on the data obtained were reported.

The pseudo-phase ion exchange (PPIE) model has been satisfactorily applied to explain the observed micellar effects.

Further investigation into more appropriately substituted hydroxamic acids is suggested in order to obtain a more complete set of data and further evaluation.

The Effects Of Peer Tutoring On A Direct Instruction Reading Program, Robert Schuyler Brooks

Masters Theses

This study evaluated the effectiveness of peer tutoring with a direct instruction reading program prior to teacher-directed instruction. Six upper level elementary students participated in the peer tutoring program and two students participated in a control group.

The findings from this study indicate that: (a) pre-exposure to direct instruction in reading lessons with peer tutoring improves student reading rate without increasing error rate, and (b) the instructional time for a teacher-directed lesson decreases when peer tutoring is a part of the reading routine. It was concluded that peer tutoring prior to teacher-directed instruction increases student reading rates without sacrificing accuracy …

Location Analysis Of The Recycling Drop Off Program In Knox County, Tennessee, Carol Michelle Donoghue

Masters Theses

This study examines the drop-off recycling program in Knox County, Tennessee, in order to evaluate the convenience of the drop-off site locations. Measures of convenience were distance, level of recycling participation, and location of the site. Surveys were administered to 461 individuals participating in the program at the three Convenience Centers with drop-off recycling facilities. The spatial analysis compared the drop-off locations to the development patterns of the surrounding area.

The survey results indicate that more people are recycling now than before the beginning of the drop-off program. More than half of those surveyed recycle at least once a week …

An Analysis Of Hydrogeologic Factors Affecting Aquifer Vulnerability In Southwestern Michigan, Steven E. Benton

Masters Theses

In southwestern Michigan aquifers are threatened by human activities. Parameter/factor weighting systems are used to rate aquifer vulnerability. Hydrogeologic factors affecting aquifer vulnerability were investigated in this study.

Well records, soil surveys, hydrogeologic reports, and partial chemical analyses were used to obtain data on the aquifers, soil types, glacial sediments, and types of contaminants. Data analysis included comparisons of means and medians, factor analysis, and Pearson and Spearman Correlation analysis.

The results indicate that the aquifers in Kalamazoo County are not protected. Depending on the type of glacial sediment, hydrogeologic factors that protect aquifers are clay thickness and the depth …

Inhibited Spontaneous Emission By Photonic Band Gaps In A Square Lattice Of Periodic Dielectric Medium, Abdullah Al-Ghamdi

Masters Theses

The concepts of band theory for electrons can be employed to describe the behavior of electromagnetic waves propagating in two-dimensional, periodic dielectric structures. These two-dimensional, periodic structures can produce photonic band gaps in which the spontaneous emission by atoms embedded in the structure is prohibited and as a result the performance of many semiconductor devices can be enhanced. The calculations are based on finding the eigenvalues of the algebraic equation for the frequencies of electromagnetic waves moving in a square lattice composed of square dielectric rods with different dielectric constants.

Fractures In The Jacobsville Sandstone And The Precambrian “W” Rocks In Eastern Marquette County, Michigan, Leonard Paul Belliveau

Masters Theses

The major fracture systems in the Jacobsville sandstone likely originated by reverse faulting on the Keweenaw fault and by glacially produced thrusting. Fracture orientations, apertures, and spacings are uniform in the Jacobsville sandstone and Lighthouse Point member of the Mona Schist, and are variable in the Lower member of the Mona schist and Compeau Creek gneiss. Fracture sets in the Compeau Creek gneiss exist in domains separated by metadiabase dikes. The metadiabase dikes relieved the strain produced by the Penokean orogeny by fracturing. Fractures present in inclusions, quartz veins, metadiabase and diabase dikes can be used to temporally evaluate the …

Eta Photoproduction Via 2H(Γη)2H*, Yan Zhang

Masters Theses

The reaction H(γη)²H^* is studied using the impulse approximation. A recent fit to the H(γη)²H^* elementary amplitude is employed in the calculation. The n-p final state is described by Reid's soft core potentials. The calculation shows very different cross sections for the final isospin 0 and isospin 1 break-up channels. The S₁₁ resonance is demonstrated to dominate the eta cross sections in the 740 MeV photon laboratory energy region. Fermi motion in the deuteron does not significantly spread the effect of the S₁₁ . All these results demonstrate that the reaction H(γη) …

The Effects Of Daily And Weekly Supervisor Feedback On The Performance Of University Clerical Staff, Christopher Benjamin Turla

Masters Theses

This study evaluated the effectiveness of a feedback system developed to increase the productivity and job satisfaction of clerical staff in a university unit that admitted and audited students. Weekly and daily feedback were compared. Employees self-recorded the quantity and type of tasks completed throughout the study. In feedback condition 1, the supervisor delivered feedback once a week to two employees and everyday to three employees. In feedback condition 2, feedback frequencies were switched such that employees who first received weekly feedback received daily feedback, and employees who first received daily feedback received weekly feedback. Job satisfaction was measured before …

A Representation Of Chemical Reactions By Labeled Graphs, Héctor Hevia

Dissertations

Graphs can be used to represent the atomic structure of chemical compounds where the vertices of the graph represent the individual atoms and the edges of the graph represent the valence bonds between a pair of atoms. M. A. Johnson (1991) introduced a graph-theoretic way to represent structural changes in chemical compounds. Thus, certain labelings of graphs called transitional labelings can be thought as representing chemical equations. Associated with these labelings, we introduce a new invariant of a graph G called the transitional value of G. The transitional value of a graph G gives an indication of how dramatic a …

Developing Language Through A Musical Program And Its Effect On The Reading Achievement Of Spanish Speaking Migrant Children, Dora Dominguez

Dissertations

The purpose of this study was to investigate the effects of a language development program that uses music as a medium of instruction on the reading achievement of Spanish speaking migrant children. Fifty-one preschool aged subjects from a Title I (Michigan Department of Education, 1987) Summer Migrant Education Program participated in the study.

The subjects were randomly divided into 2 groups. They were provided oral language instruction to help them acquire the language of the basal readers. In other words, the vocabulary and language patterns found in a basal reading program were built into the daily language lessons. In the …

Basement Control On The Development Of Selected Michigan Basin Oil And Gas Fields As Constrained By Fabric Elements In Paleozoic Limestones, Robert Thomas Versical

Masters Theses

Hydrocarbon bearing structures in the Paleozoic section of the Michigan basin possess different structural styles and orientations. Quantification of the direction and magnitude of shortening strains by applying a calcite twin-strain analysis constrains the mechanisms by which these structures may have developed. The calcite twin-strain analysis and fracture orientations in Paleozoic rocks indicate that the mean direction of compression controlling structural development ranged from SE-NW to nearly E-W. This direction of compression nearly parallels the majority of structures in the basin, and provides insight into their origin.

The structural geometries of fields considered in this study can be explained by …

Transformations Of Graphs And Digraphs, Elzbieta B. Jarrett

Dissertations

Some distances defined on graphs depend on transforming one graph into another. Two of these transformations are edge rotation and edge slide. In this dissertation, extensions and generalizations of these transformations are investigated.

Chapter I begins with some preliminary definitions and known results. Then two types of digraph transformations are introduced and their properties are studied.

Some measures of distance between graphs and distance between digraphs are defined in Chapter II. Also distance graphs and digraphs associated with these measures are introduced. Several known results concerning this topic are generalized and new results are presented.

Chapter III is devoted to …

Surgical Techniques For Constructing Minimal Orientable Imbeddings Of Joins And Compositions Of Graphs, David L. Craft

Dissertations

The various cases within the proof of the Heawood Map-Coloring Theorem, which established the genus of the complete graphs, utilized various techniques--some for the first time. This activity spurred interest in determining the genus of various other classes of graphs. However, very few generally applicable techniques have been developed, beyond those used in the proof of this famous theorem. Finding genera of arbitrary graphs remains a very difficult problem.

In this dissertation, we describe two surgical techniques for imbedding graphs. The first construction, called a graphical surface,views an orientable surface as a fattened graph, i.e., vertices become spheres and edges …

Total Blood Cholesterol, Blood Triglyceride, And Blood Hdl Correlation, Rebecca Lynn Babler

Masters Theses

The purpose of this investigation was to determine the relationship between total blood cholesterol levels, blood triglyceride levels, and blood HDL levels in men and women 20 to 80 years of age. All subjects fasted for 12 hours prior to having their blood drawn.

The computer program SPSSX (SPSSX, Inc., 1988) was used along with subprograms CONDESCRIPTIVE, CORRELATION, and ANOVA. Pearson Product Moment Correlations were calculated for all subjects, for male subjects, and for female subjects.

The study revealed a low correlation coefficient between blood cholesterol levels and blood triglyceride levels for all subjects, female subjects and male subjects. There …

Time Delay Neural Networks And Speech Recognition: Context Independence Of Stops In Different Vowel Environments, Gregory Andrew Makowski

Masters Theses

A series of speech recognition experiments was conducted to investigate time-dynamic speech recognition of stop consonants invariant of vowel environment using data from six talkers. The speech preprocessing was based on previous studies investigating acoustic characteristics which correlate to the place of articulation (Blumstein and Stevens 1979). The place of articulation features were statistically abstracted using four moments and the energy level of the speech sample.

Both statistical and neural network pattern recognition methods were used. Statistical methods included linear and quadratic discriminant functions, maximum likelihood estimator (MLE) and K-nearest neighbors (KNN). The neural network approach used was Time Delay …

A Valence Quark Model, Tony A. Forest

Masters Theses

A quark model of the baryons has been developed for calculating properties of nucleons which can be useful in nuclear interactions. A Hamiltonian, motivated by QCD, was diagonalized in a harmonic oscillator basis. In addition to predicting the proton charge radius and Delta-Nucleon mass difference, this work also yields a value of the axial vector coupling constant which compares well with experiment. Electric and magnetic form factors represent the major success of this model. The electromagnetic transitions predicted by this model compete well with other models but are not able to reproduce experimental results completely. The advantage of this model …

Double Ionization Of Helium By Intermediate To High Velocity He+ Projectiles, Jun Forest

Masters Theses

Ionization of helium target atoms by He⁺ projectiles colliding with helium at energies of 0.125 to 3.0 MeV/u is investigated. Cross sections for single and double ionization, and ratios o f double-to-single ionization are determined for each outgoing projectile charge state, and are compared to previous studies. For the lowest energies investigated, the ratios are consistent with the two-step mechanism in which the projectile interacts separately with each target electron. At the highest energies, the ratios reach nearly constant values indicating approach to the high velocity limit. At these high energies, however, the ratios are all higher than the …

Facies Analysis And Diagenesis Of The Lower Engadine Group And The Manistique Group In Manistee, Mason And Oceana Counties, Michigan, Karen S. Mater

Masters Theses

Three lithofacies in the Lower Engadine Group, and four lithofacies in the Manistique Group were identified. Facies patterns suggest a transgression during deposition of the Manistique Group and Lower Engadine Group.

Environments of deposition were determined by analysis of facies found in the Lower Engadine and Manistique Groups using available cores, petrophysical logs, and well cuttings. The diagenetic sequence of events was identified using thin sections.

Diagenesis has greatly altered original fabric and porosity. Hydrocarbon accumulation in these units is dependent on facies distribution, diagenesis, and structural features.

Resonant Electron Transfer And K-Shell Excitation Of FQ+ (Q=6,8) In Collisions With Neutral He And H2 Targets, Konstantinos E. Zaharakis

Masters Theses

Measurements of resonant transfer and excitation (RTE) were conducted for 16.5-38 MeV F⁶⁺ (Li-like) ions colliding with H₂. In the RTE process electron capture and projectile excitation take place simultaneously due to the electronelectron interaction. In previous work, for the same collision system, at the Oak Ridge National Laboratory (Oak Ridge, TN) , the magnitude of the measured RTE cross sections was found to be nearly a factor of two smaller than theory. In order to investigate RTE in F⁶⁺ H₂ collisions more completely, we undertook measurements at Western Michigan University using the EN tandem …
