Nickel Subsulfide Can Protect Human Fibroblasts From The Mutagenic Effect Of Benzo[A]Pyrene Diolepoxide, Samir M. Hamdan

Masters Theses

Cancer researchers are interested in identifying the environmental causes and synergistic influences of different carcinogens. It is important to examine the combined effect of multiple carcinogens since this is a more realistic representation of the true environmental situation in which we are exposed daily. Our study has reported that pretreating human fibroblasts with nickel subsulfide followed by the simultaneous treatment with both nickel subsulfide and benzo[a]pyrene diolepoxide (BPDE) can protect human fibroblasts from the mutagenic effects of BPDE. These results correlate well with our previous chromium-BPDE co-treatment work, suggesting a transition metal dependent protective effect. This protective effect was dependent …

An Analysis Of Texture Resulting From Thermomechanical Processing Of Ti-6al-V, David J. Brock

Masters Theses

An investigation of texture and microstructure formation in Ti-6Al-4V after thermomechanical processing and heat treating was performed. X-ray diffraction was used to measure prismatic and pyramidal pole figures. These pole figures were used to calculate basal pole figures, which showed significant changes in texture from heavy rolling and near or above β-transus heat treatments. Primary texture components were found to be strengthened by near β-transus heat treatments. For heavily rolled material, above β-transus heat treatments were found to reverse the primary texture components order of dominants. Heavy rolling was found to reduce the RD component and strengthen the TD.

The Effects Of Phonological Awareness Activities On At-Risk First Grade Readers, Kimberly L. Van Belois

Masters Theses

The purpose of this study was to look at a variety of phonological awareness studies and their impact on students with reading difficulties and to implement a program to develop student's reading abilities and look at its impact on student's knowledge of vowel and consonant recognition, vowel sounds, and sight words. Phonological awareness can be defined as one's sensitivity to, or explicit awareness of, the phonological structure of words in one's language. A number of researchers (eg., Libennan, Shankweiler, & Liberman, 1989) have concluded that adequate awareness of the phonological structure of words helps to make learning to read words …

Community Empowerment And Social Policy Design: A Case Study Of The Creation Of A School-Based Health Center, R. Ian Costello

Masters Theses

Studies of community empowerment have shown the benefits of involving recipient communities in the process of designing and implementing social aid programs. One of these benefits is the empowerment of previously disenfranchised individuals and communities. Through qualitative ethnographic research, this thesis shows how residents of one low-income community in South-West Michigan have become more empowered through their involvement in the design and implementation of a school-based health center.

The Lost Treasure Of Valencia: Fugitive Muslims From The Kingdom Of Valencia 1290-1410, Michael A. Ryan

Masters Theses

The fourteenth century, an epoch infamous for war, disease, famine, and devastation across the whole of Europe, also saw an increase in the number of fugitive Muslims from the Christian kingdom of Valencia. Due to the reconquest of Valencia in the thirteenth century, an immense Muslim populace found itself subject to a dominant Christian minority. These Muslims had been either enslaved outright for resisting the Christian domination, or had been placed into a semi-free status. The members of this latter group were known as the Mudejars, and like the Muslim slaves, fled when their social and political standings were in …

Delectatio Et Utilitas In Hrotsvit Of Gandersheim's Resuscitatio Drusianae Et Calimachi, Mary Maxine Browne

Masters Theses

Hrotsvit of Gandersheim (935-1002 A.D.) wrote her play, Resuscitatio Drusianae et Calimachi, as the other five plays which Hrotsvit composed, as an adaptation of a hagiography from the apocryphal Acta Johannis. Written in the spirit of the tenth-century didactic esthetic delectatio et utilitas, Hrotsvit adapted the narrative of the legend to the Terentian comedic form, that she might instruct her monastic audience according to the delectatio et utilitas esthetic.

This discussion focuses on the sources and backgrounds of Hrotsvit's play, followed by Hrotsvit' s adaptive treatment of the characters in Resuscitatio Drusianae et Calimachi with a …

This study also assessed the ability of the Arousal Predisposition Scale to predict treatment outcome. Subjects received treatment for snake, spider, rat, mouse, or crawling insect phobia. Three groups were utilized (treatment, phobic control and non-phobic control). The treatment session included both behavioral and self-report measures of anxiety. Almost all treatment subjects showed dramatic improvement on both of these types of measures during posttest and one-month follow-up. The treatment and non-phobic control groups were …

Improvement Of Epa Method 8330: Complete Separation Of Explosives Using A Two Phase Approach, Michael J. Lang

Masters Theses

A wide range of primary and secondary contaminants is found in environmental matrices containing explosive residues. HPLC methodology for the detection of explosive is now standardized in EPA Method 8330, and represents the most common method currently used for explosive analysis. However, co-elution of some of the analytes occurs even using method 8330. As a result, explosive analysis using HPLC have required the use of a confirmation column in an additional analysis step.

In the current work, all of the compounds in the EPA 8330 explosives list were resolved using a single HPLC separation. While the EPA 8330 HPLC conditions …

The second experiment was designed to determine maximum acceptable task frequencies (MAF) for males performing a simulated pouring operation at …

Mechanism By Which Insulin And Its Mimetics, Selenate And Vanadate, Regulate Glucose-6-Phosphate Dehydrogenase Gene Expression, Sanjay M. Jivraj

Masters Theses

Glucose-6-phosphate dehydrogenase (G6PDH) is a key enzyme of the pentose phosphate pathway. It controls the carbon flow through this pathway, producing reducing equivalents in the form of NADPH to meet the cellular need for reductive biosynthesis and the maintenance of the cellular redox state. Hepatic expression of G6PDH has been shown to be regulated by hormones, nutrients and some growth factors, however the mechanism by which these factors regulate G6PDH gene expression has not been characterized. Here we investigate the mechanism by which insulin and its mimetics, selenate and vanadate, regulate G6PDH gene expression.

Insulin exerts its tissue specific affect …

Image Processing Based On A Fuzzy Logic Edge Detection Algorithm, Jamshid Khazaai

Masters Theses

One of the major problems in image processing is that of efficient edge detection. This is because the automated determination of an edge requires a subjective interpretation of just what the image author intended to be an edge. By training an edge determination algorithm to be sensitive to edges in a consistent manner, efficiency can be improved. This is the central idea of this thesis in which I define edge occurrences for the intensity (monochrome) images using fuzzy sets.

Edge characteristic functions are proposed for detecting edge pixels within a desired block of an (intensity and binary) image based on …

Stage-Dependent Expression Of Target-Derived Influences Stimulates Axon Outgrowth In Hirudo Medicinalis, Tina M. Harik

Masters Theses

Our lab has been investigating the development of neuronal phenotype and circuitry in Hirudo medicinalis. Early in embryogenesis the heart excitor (HE) motor neuron selectively extends multiple arbors into the body wall prior to heart tube (HT) formation. HE contact with HT primordium at later stages of development results in remodeling such that arbors are elaborated on the HT, while those in the body wall are retracted. HT-derived cues are necessary for HE remodeling (Jellies, 1995. Am. Zool. 35:529; Jellies and Kopp, 1995. Invert. Neurosci. 1:145). HT and body wall explants were co-cultured to investigate the possible influences of …

The Implementation Of Group Mentoring Between At-Risk Teenage African American Males And Successful Adult African American Men, Cornell Mathis

An investigation of the composite reduction provides the foundation for establishing the following definition of the group mentoring experience. The mentees are drawn to the mentors by mutual respect developed through the use of a special language. Availability leads to bonding between the mentees and mentors. The relationships are fostered by the authenticity of both individuals while producing social enlightenment …

Glucose Mediated Effects On Glucose-6-Phosphate Dehydrogenase Expression, Daryl Arkwright

Masters Theses

Circulating high glucose levels are believed to cause oxidative stress which is implicated in a number of pathological conditions such as cancer, aging, and diabetes. Oxidative stress regulates the expression of glucose-6-phosphate dehydrogenase (G6PDH), the key enzyme in the pentose phosphate pathway which provides reducing equivalents in the form of NADPH. These reducing equivalents are also required by fatty acid synthase (FAS), the enzyme which catalyzes fatty acid biosynthesis. We examined whether glucose, a known inducer of oxidative stress, could regulate either G6PDH or FAS activity in primary rat hepatocytes. We tested the effects of glucose alone or in combination …

The Effects Of Reminiscence Therapy On The Elderly Client's Satisfaction With Nursing Care, Nancy Strong

This study tested if reminiscence therapy would improve client satisfaction with nursing care. An experimental post test only design was used on 39 clients in a moderate sized home care agency in the Midwest. Ages ranged from 65 to 98. A single, one-on-one reminiscence session was done with 22 subjects in their homes after a routine nursing visit. The control group subjects did not receive the reminiscence intervention. The groups were homogeneous except for the number of hospitalizations experienced in the past year. The control group had a significantly higher number.

The Forbes Patient Satisfaction Questionnaire, modified for the home …

The Relationship Of Hardiness And Perceived Social Support To Nurses' Appraisals Of Stress, Susan A. Groesser

Masters Theses

Lazarus' Stress and Coping Theory was used to examine the relationship between hardiness, social support, and nurses’ appraisal of stress as a threat or challenge. This descriptive correlational design used a convenience sample of 40 registered nurses on orientation at a large West Michigan hospital.

Hardiness and social support were dichotomized by splitting them at the median. The proportion of the sample viewing orientation as a challenge versus threat was not significantly different regardless of their hardiness or social support status. The results were limited by lack of variation in stress appraisal (77% challenge) and hardiness levels, sample size, and …

The Contemporary Migration Of Russian-Germans From Russia And Kazakhstan To Germany: A Case Study In Migration Geography, Jacquelin K. Tylzynski

Masters Theses

Since the collapse of communism in Central Europe and the former Soviet Union in the late 1980's/early 1990's over two million ethnic Germans have migrated to Germany (predominantly from Russia and Kazakhstan). Ethnic Germans are descendants of Germans who migrated to Central Europe and to Russia centuries ago who are returning to their historic roots since they have been allowed to leave. The reason ethnic Germans are migrating to Germany stems from a strange law written into West Germany's post-World War II constitution (in 1949) that promised ethnic Germans and their descendants the "right to return" to Germany; however, the …

Simulation Of The Hybrid Fuzzy-Boolean Finite State Machine (Hfb-Fsm), Hamed Shakouri

Masters Theses

Several models of fuzzy finite-state automata have been proposed in the literature. One model which benefits from the existing algorithms for designing Boolean finite-state machines, has been proposed by J. L. Grantner [8]. This model, which is called Hybrid Fuzzy-Boolean Finite State Machine (HFB-FSM), along with its algorithmic design procedure, can be used for implementing dynamic linguistic systems [7,8,13]. In this thesis we have developed a simulation program for the HFB-FSM model using C++ programming language. In order to simulate a HFB-FSM model, the user provides the information defining the system's behavior. Based on the algorithm proposed in [8], the …
