Theoretical Studies Of Few-Body Problems, Uttam Chowdhury

Doctoral Dissertations

"Heavy ion collisions with atomic and molecular targets produce many outcomes. The Schrödinger equation is not analytically soluble for more than two mutually interacting particles. As a result, theory must resort to using approximations, the validity of which is determined by comparison with experiment. This work is focused on finding better approximations to describe ionization and capture processes in proton collisions.

Proton-impact ionization of molecular hydrogen is treated as a 3-body problem. Usually the target is treated as an atomic target and the results are multiplied by an ad hoc factor to account for the molecular structure. Measured cross sections …

Underground Mine Fire Simulation Using Multiscale Modeling Approach, Xichen Zhang

Doctoral Dissertations

"Underground mine fires have always been a major concern. Past events show that fire poses a severe safety hazard to mine workers, and causes tremendous economic loss to the mine and surrounding communities. A good understanding of the interaction between a mine fire and the mine ventilation network is crucial for effective fire emergency planning and hazard control. Unfortunately our understanding of a fire is still limited due to the complex nature of mine fires and a lack of adequate resource for studying them.

A new multiscale modeling approach coupling conventional 1D and 3D techniques has shown to be a …

Sobuz, Rashidul Haque, Kaisar A. Talukder, Shahida Qureshi, Anita K. M. Zaidi, Doris M. Haverstick, Eric R. Houpta

Department of Paediatrics and Child Health

Diarrhea can be caused by a range of pathogens, including several bacteria. Conventional diagnostic methods, such as culture, biochemical tests, and enzyme-linked immunosorbent assay (ELISA), are laborious. We developed a 7-plex PCR-Luminex assay to simultaneously screen for several of the major diarrhea-causing bacteria directly in fecal specimens, including pathogenic Aeromonas, Campylobacter jejuni, Campylobacter coli, Salmonella, Shigella, enteroinvasive Escherichia coli (EIEC), Vibrio, and Yersinia. We included an extrinsic control to verify extraction and amplification. The assay was first validated with reference strains or isolates and exhibited a limit of detection of 10(3) to 10(5) CFU/g of stool for each pathogen as …

Mitchell, Evans Afriyie-Gyawu, Nii-Ayi Ankrah, Jonathan H. Williams, Jia-Sheng Wang, Pauline E. Jolly, R. J. Nachman, Timothy D. Phillips

Environmental Health Sciences: Faculty Publications

Fumonisin B1 (FB1) is often a co-contaminant with aflatoxin (AF) in grains and may enhance AF’s carcinogenicity by acting as a cancer promoter. Calcium montmorillonite (i.e. NovaSil, NS) is a possible dietary intervention to help decrease chronic aflatoxin exposure where populations are at risk. Previous studies show that an oral dose of NS clay was able to reduce AF exposure in a Ghanaian population. In vitro analyses from our laboratory indicated that FB1 (like aflatoxin) could also be sorbed onto the surfaces of NS. Hence, our objectives were to evaluate the efficacy of NS clay to reduce urinary FB1 in …

The Influence Of Federally Qualified Health Centers On Selected Ambulatory Care Sensitive Conditions In Georgia, Mary W. King Mathis

College of Graduate Studies: Theses & Dissertations

Author's Abstract: Ambulatory care sensitive conditions (ACSCs) resulting in hospitalizations make up a substantial proportion of health care costs, but should not because these conditions are manageable in quality primary care settings that promote prevention in an effort to avoid exacerbations that can lead to hospitalization. The use of emergency departments (EDs) as a safety net for ACSCs has increased the burden on hospitals because patients who do not regularly utilize primary care often resort to the use of EDs for treatment of ACSCs. Federally qualified health centers (FQHCs) are designed to provide consistent, high-quality primary care to all people, …

"...Bless Her Little Heart!": The Culture Of Honor And Emotion Recognition, Forrest J. Rackham

College of Graduate Studies: Theses & Dissertations

Author's abstract: Some researchers assert that cultural display rules may explain differences in perceiving emotions (Matsumoto, Yoo, & Chung, 2010). The current study examined the display rule of masking within the Southern culture of honor. It was hypothesized that masking within the culture of honor negatively affects emotion perception sensitivity, particularly in the speed and accuracy of recognizing anger. Southern undergraduate students were primed with the culture of honor and then presented with the Emotional Expression Multimorph Task. Participants chose one of the six emotions (i.e., sad, happy, surprise, fear, disgust, or anger). It was hypothesized participants in the masking …

Children have even less control and feel the effects of additives and chemicals more than adults. Many of the effects of bioengineered foods are unknown at this time. My dissertation will be a theoretical exploration of biotechnology in food using a bioethical critical perspective. I use my personal experience and research to examine the effects of processed and genetically engineered foods on people, especially …

Academic Optimism Of Schools And Student Achievement, Pamela J. Mckinnon

College of Graduate Studies: Theses & Dissertations

The pressure to perform well on high stakes testing may have caused many educational leaders to shift their focus away from developing a healthy organization that may enhance and possibly even predict student achievement to simply focusing on test scores. Hoy, Tarter and Hoy (2006) suggested that high levels of Academic OptimismAO (including collective teacher efficacy-CTE, faculty trust in parents and students-FT, and academic emphasis-AE), when controlling for SES, is a strong force in predicting academic achievement. This study attempted to support previous research findings and to provide educational administrators with a framework for improving school organizational health for the …

Social Emotional Competence And Teacher Stress, Leslie Carole Forcina

College of Graduate Studies: Theses & Dissertations

Teacher stress and continuing high attrition rates for the teaching profession have significant multiple impacts, although arguably the most important is student achievement. Research indicates that as teacher stress increases to high levels, teacher effectiveness decreases. Attempts to reduce stress have historically focused on organizational or systemic change with minimal success. There remains a clear and distinct call to pursue individual factors that may influence teachers’ abilities to moderate stress. Social emotional competence (SEC) is a set of skills that allows individuals to understand themselves, their emotions, the social context as well as relationships and decision making. Existing research has …

Curriculum Circus: Juggling Curriculum, Science, And The Arts, Domenica Devine

College of Graduate Studies: Theses & Dissertations

Education should open the door to better lives and better jobs. The fact is that it does not. In part, there are many causes including rigidity, political interference, and the separation between disciplines that we teach without context and without dialogue with our students. Specifically, I think that we should use education as a way to help students make better choices and have a better life. One way we can do it is by reconciling science with the other disciplines. And that is what is at the heart of curriculum studies.

There is a pervasive belief that the Western ideology …

Factors Associated With Adult Literacy Student Outcomes In Campus-Based Versus Community-Based Programs, Charles Hall

College of Graduate Studies: Theses & Dissertations

In Georgia, the Technical College System of Georgia (TCSG) formally trains over 100,000 adult literacy students each year free of charge at a variety of campus-based and community-based programs located at community centers, churches, libraries, or businesses. A common, yet unproven, assumption among senior administrators and adult literacy faculty members at TCSG colleges is that adults who attend literacy classes embedded in the traditional college campus environment have better academic outcomes than those who attend only community-based programs. However, a gap currently exists in the literature with respect to a clear understanding of which student outcome variables are impacted when …

Evaluating Relationships Between Mercury Concentrations In Air And In Spanish Moss (Tillandsia Usneoides L.), Kathryn T. Sutton

College of Graduate Studies: Theses & Dissertations

Mercury is a potent neurotoxin that is transported globally in vapor form. A major source of mercury contamination to soil, water, and biota is atmospheric deposition. Therefore, comprehensive monitoring of atmospheric concentrations is important. Limitations of conventional atmospheric measurement techniques include high cost and lack of temporal or spatial integration. Bioindicators, however, may serve as an integrative tool to add to conventional mercury measurement techniques. Spanish moss (Tillandsia usneoides L.) is a potential bioindicator of atmospheric mercury concentration in the southeastern United States because it is an abundant epiphyte that absorbs and accumulates atmospheric pollutants. A study was conducted in …
