Hydrogeochemical Delineation Of A Groundwater Flow System, Berrien County, Michigan, Patrick J. Bartnik Apr 1995

Hydrogeochemical Delineation Of A Groundwater Flow System, Berrien County, Michigan, Patrick J. Bartnik

Masters Theses

The objective of this study was to examine the possibility of determining groundwater flow directions from natural variations in groundwater chemistry. Groundwater samples were analyzed for major cation and anion concentrations. These data were to have been contoured and then compared with groundwater flow maps generated by conventional methods. The purpose was to determine whether a correlation could be drawn between the two methods. However, the results of the study did not allow for this comparison.

The plotted major cation and anion data did not lend themselves to contouring, which suggests that greater control may be required during the selection …


Structural Effects On Micellar Catalyzed Hydrolysis Of Hydroxamic Acids With Perfluorooctanoic Acid As Surfactant, Xing Zhang Apr 1995

Structural Effects On Micellar Catalyzed Hydrolysis Of Hydroxamic Acids With Perfluorooctanoic Acid As Surfactant, Xing Zhang

Masters Theses

This thesis demonstrated the structural effects on micellar catalyzed hydrolysis of hydroxamic acids with prefluorooctanoic acid as the reactive counterion surfactant in aqueous acetonitrile solution.

For different hydroxamic acids, the observed pseudo-first order rate constant-surfactant concentration profiles were obtained and were used in the determination of critical micellar concentrations (cmc).

The micellar catalytic effect was satisfactorily explained by the pseudo-phase ion exchange (PPIE) model. The PPIE model was successfully applied in the determination of the reaction rate constants both in the water phase and in micellar pseudo-phase.

Further investigation into more appropriate hydroxamic acids is suggested in order to obtain …


An Analysis Of The Primordial Soup Hypothesis With Respect To Dna Structure And The Genetic Code, Jennifer A. Hart Mar 1995

An Analysis Of The Primordial Soup Hypothesis With Respect To Dna Structure And The Genetic Code, Jennifer A. Hart

Masters Theses

The primordial soup hypothesis is currently the most popular origin of life theory. This hypothesis suggests that DNA and self-replicating organisms were formed out of a warm, aqueous environment on the surface of the prebiotic earth. However, recent studies have shown that the primordial soup hypothesis is not only lacking in factual support, it is also internally flawed. The primordial soup hypothesis is statistically impossible, and it does not adequately account for the origin of the specified complexity of the genetic code. The very nature of the genetic code requires an intelligence source. Universal experience shows that specified complexity is …

Factors Associated With Underachievement In Eighth-Grade Children, Barbara A. Moore Jan 1995

Factors Associated With Underachievement In Eighth-Grade Children, Barbara A. Moore

Masters Theses

This study investigated characteristics of underachieving adolescents. The Iowa Tests of Basic Skills (ITBS; Hieronymous, et al., 1990) and grade point averages provided the basis for selection of 83 eighth grade students into achiever and underachiever groups. Results indicated that underachievement was significantly related to males, number of absences, and number of discipline referrals, but not to race and notice of special education records. Overall self-esteem, as measured by the Self-Esteem Index (SEI; Brown & Alexander, 1991), and the subscale measure of perceptions of weak academic competence were positively related to level of underachievement/overachievement. Composite measure of behavioral/emotional problems, as …

Novel Compounds (Including Transition-Metal Complexes) Based On 1,10-Phenanthroline-5,6-Dione, Hui Zhou Jan 1995

Novel Compounds (Including Transition-Metal Complexes) Based On 1,10-Phenanthroline-5,6-Dione, Hui Zhou

Masters Theses

This thesis describes the synthesis of the transition metal complex [(bpy) 2OsII (pptd)] (PF6)2·2H2O, an analog of [(bpy) 2RuII (pptd)] (PF6)2·2H2O. Spectroscopic and electrochemical data on this complex are reported here. It was found that the electronic communication between the metal center and the pteridinedione portion of pptd did not appear to be enhanced in the Os(II) complex relative to its Ru(II) analog. The increased ability of Os(II) to undergo backbonding appeared to affect only the 1,10-phenanthroline portion of pptd.

A useful …

Pynchon, Dionysus And America: In Search Of The Pig That Got Away, Andreas Gerling Jan 1995

Pynchon, Dionysus And America: In Search Of The Pig That Got Away, Andreas Gerling

Masters Theses

This work seeks to analyze Western thought as a system. As a case study representative of this system, I have chosen the United States of America, as it started as a strange experiment in purely Apollonian thought, which has largely remained a closed system and has become the primary engine of cultural change in the twentieth century. As the tools for my analysis, I have chosen the dialectic represented in the mythical opposites Dionysus and Apollo and the counter cultural reaction by a number of post World War II authors, most notably Thomas Pynchon, to the "American Dream."

America began …


A Brief Discussion Of The History, Role, And Function Of The School Psychologist In The Former Soviet Union And Russia, Todd W. Knutson Jan 1995

A Brief Discussion Of The History, Role, And Function Of The School Psychologist In The Former Soviet Union And Russia, Todd W. Knutson

Masters Theses

School psychology in the former Soviet Union and Russia had its beginnings as the field of Pedology which thrived in the early 1900s in Europe and in the former Soviet Union. School psychological services, in Western psychometric sense, have been virtually dormant since Pedology's downfall following ideological conflicts with Communist leaders in 1936 when standardized testing was banned in the U.S.S.R. This paper sketches a brief history of school psychology in the former Soviet Union and Russia, outlines the educational system, reviews the Soviet research on mental retardation, and calls for the sharing of general information related to international school …


Investigation Of The Relationship Between Language & Mathematics In Regards To Problem Solving, Heather A. Grant Jan 1995

Investigation Of The Relationship Between Language & Mathematics In Regards To Problem Solving, Heather A. Grant

Masters Theses

While previous research has established language as a component of mathematical performance (Kintsch, 1988; Simon, 1985), none have identified a relationship between language and mathematics. This study was conducted to examine the relationships between language and mathematical abilities, specifically problem solving abilities and concept knowledge.

The subjects consisted of 29 fifth-grade students selected from an elementary school in central Illinois. These students were not receiving special education services.

A Neural Network Thrust Force Controller To Minimize Delamination During Drilling In Graphite Epoxy Laminates, Robert B. Stone Jan 1995

A Neural Network Thrust Force Controller To Minimize Delamination During Drilling In Graphite Epoxy Laminates, Robert B. Stone

Masters Theses

"Delamination is a well-recognized problem associated with drilling in fiber-reinforced composite materials (FRCM). The most noted problems occur as the drill enters and exits the FRCM. Since drilling is often a final operation during assembly, any defects introduced in parts by drilling represent an expensive loss. Studies based on linear elastic fracture mechanics theory have proposed critical thrust forces in the various drilling regions that will prevent crack growth or delamination. Using these critical thrust force curves as a guide, a thrust force controller was developed to minimize the delamination while drilling in graphite epoxy laminates. A neural network control …

Eigenproperties Of Nonclassically Damped Dynamic Systems, Daniel Patrick Malone Jan 1995

Eigenproperties Of Nonclassically Damped Dynamic Systems, Daniel Patrick Malone

Masters Theses

"This thesis develops perturbation series solutions for the eigenvalues and eigenvectors of nonclassically damped dynamic systems for the case where the unperturbed system has repeated eigenvalues. The case of repeated eigenvalues is much more complicated than the case of perturbing a system with distinct eigenvalues. Because of this difficulty, only a specific category of dynamic systems with repeated eigenvalues is addressed. Namely, only those systems that when perturbed have series solutions of the form of a power series. This category of systems can be easily identified by an a priori check developed in the application section of this thesis. The …
