The Future Of Nuclear Security: A Medical Physicist’S Perspective, Katharine E. Thomson
The Future Of Nuclear Security: A Medical Physicist’S Perspective, Katharine E. Thomson
International Journal of Nuclear Security
Planning for the future of nuclear security is a vital and complex task, requiring cooperation and contribution from many disciplines and industries. This diversity of expertise should include the medical sector, which faces many of the same challenges as the nuclear industry: controlling access to dangerous material, creating a strong security culture, cooperating with the wider world and engaging the public.
Medical physicists, of which the author is one, oversee all aspects of small-scale radiation use. This paper discusses three key areas increasingly important to both medical and nuclear uses of radioactive materials: public engagement, prevention of nuclear and radiological …
Investigating The Regulation Of Indole-3-Acetic Acid Production By The Plant Associated Microbe Pantoea Sp. Yr343, Kasey Noel Estenson
Investigating The Regulation Of Indole-3-Acetic Acid Production By The Plant Associated Microbe Pantoea Sp. Yr343, Kasey Noel Estenson
Doctoral Dissertations
The auxin indole-3-acetic acid (IAA) plays a central role in plant growth and development and many plant-associated microbes produce IAA. Several IAA biosynthetic pathways have been identified in microbes which use the precursor tryptophan. Pantoea sp. YR343, which was isolated from the Populus deltoides rhizosphere, is a robust plant root colonizer that produces IAA. Using genomic and metabolomics analyses, we predicted that the indole-3-pyruvate (IPA) pathway is the major pathway in Pantoea sp. YR343 for IAA production. To better understand IAA biosynthesis and the effects of IAA exposure on cell physiology, we performed proteomics on Pantoea sp. YR343 grown in …

Description And Practical Application Of The Physiologic Distribution Of 3’-Deoxy-3’-[18f]Fluorothymidine In Companion Animals, Joshua Alan Rowe
Doctoral Dissertations
Access to positron emission tomography (PET), and more recently PET combined with computed tomography (PET/CT), is increasing in veterinary medicine. This molecular imaging technology allows clinicians to map biological functions within patients based on the distribution and selective uptake of specialized positron-emitting radiopharmaceuticals. Although most clinical studies utilize 2-deoxy-2-[18F]fluoro-Dglucose (18FDG), a versatile but relatively nonspecific tracer that interrogates the energy metabolism of tissues, there is a growing need to establish reference values for alternative or adjunct tracers in veterinary species. Among these is 3’-deoxy-3’- [18F]fluorothymidine (18FLT), a thymidine analog that selectively accumulates …

Do Personal Factors And Interpersonal Influences Affect Commitment To A Plan Of Action For Physical Activity Among African-American Women?, Bobbie W. Brown
Doctoral Dissertations
The lack of physical activity (PA) among African American (AA) women is a predisposition to chronic diseases associated with obesity. Women, particularly AA women, who are between 35 and 60 years of age, are particularly noted to be at highest risk for developing obesity-related chronic diseases. Few PA studies have included AA women older than 25 years of age and younger than 65 years of age (Carter-Parker, Edwards, & McCleary-Jones, 2012).
All analyses were conducted using SPSS Version 21 (Armonk, NY: IBM Corporation) and statistical significance was assumed at an alpha value of .05. The assumption of normality for continuous …

The New Parallel: Urban And Agrarian Political, Environmental, And Architectural Landscapes Of The Demilitarized Zone, Robert Vincent Truka
Masters Theses
North and South Korea share the most heavily armed military border in the world. Technically both sides are still at war dating back to 1950. The 38th parallel, also known as The Demilitarized Zone (DMZ) is a 156-mile long by 2.5- mile wide border condition with over two million plus known landmines buried with-in its boundaries. The Juxtapositions of the financial, political, economical, and military modalities could not be more drastically different between North and South Korea. North Korea is a communist autocratic military dictatorship and has one of the worlds lowest Gross Domestic Products (GDP). South Korea is a …
Histomonas Elisa, Jessica L Martinez
Histomonas Elisa, Jessica L Martinez
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Histomonas meleagridis is a protozoan parasite of avians and is the causative agent in Histomonosis, commonly known as Blackhead Disease. Current methods for diagnosing the presence of H. meleagridis are limited to parasite culture or Polymerase Chain Reaction (PCR) to amplify target DNA. This project aims to develop an enzyme-linked immunosorbent assay (ELISA) for faster and more sensitive diagnosis of Histomonas infections. Cultures of H. meleagridis parasites were purified, and surface antigens were extracted using a spectrum of chemical solutions. The various antigen solutions were subjected to an ELISA, with serum from birds immunized for H. meleagridis as positive controls. …
Social Status Modulates Restraint- Induced Neural Activity In Brain Regions Controlling Stress Vulnerability , Sahba Seddighi, Matthew A. Cooper
Social Status Modulates Restraint- Induced Neural Activity In Brain Regions Controlling Stress Vulnerability , Sahba Seddighi, Matthew A. Cooper
Haslam Scholars Projects
Understanding the cellular mechanisms that control resistance and vulnerability to stress is an important step toward identifying novel targets for the prevention and treatment of stress-related mental illness. Dominant and subordinate animals have been shown to exhibit different behavioral and physiological responses to stress, with dominants often showing stress resistance and subordinates often showing stress vulnerability. We have previously found that dominant hamsters exhibit reduced social avoidance following social defeat stress compared to subordinate hamsters, although the extent to which stress resistance in dominants generalizes to non-social stressors is unknown. In this study, dominant, subordinate, and control male Syrian hamsters …
Rural Appalachian Person And Family Decision Making At End Of Life, Mary Lou Clark Fornehed
Rural Appalachian Person And Family Decision Making At End Of Life, Mary Lou Clark Fornehed
Doctoral Dissertations
The dynamics of delivering care to persons at end of life (EOL) have dramatically changed in the last twenty years. Improved management of chronic illness and provision of aggressive life sustaining measures for an illness once deemed fatal are more common, significantly increasing longevity. While it is estimated that more than 40 million persons with life-limiting illness worldwide are candidates for some form of palliative or end-of-life care (EOLC), less than 14% of them will receive it.
When coping with life-limiting illness, people and their families are asked to make many complex and difficult decisions about EOL, palliative, or hospice …

Evaluation Of Increased Targeted Enforcement And Community-Based Outreach And Education Programs To Increase Nighttime Seatbelt Use In East Tennessee, Kwaku Frimpong Boakye
Doctoral Dissertations
According to the National Highway Traffic Safety Administration (NHTSA), motor vehicle crashes are the leading cause of death among people aged 1-54 in the United Sates. In 2015, the number of motor-vehicle deaths on U.S. roadways totaled 35,092, a 7% increase from 2014 (32,744). Though lower gas prices and increased vehicle mileage combined with risky driving behaviors (e.g. speeding, driving while texting) account for the increased fatality rate, seatbelt non-use has been a significant contributory factor. It is estimated that nearly half (48%) of passenger vehicle occupants involved in fatal crashes each year are unrestrained.
In a recent 2014 report …
Using The Suprachiasmatic Nucleus As A Model System To Assess Tolerance And Withdrawal To Alcohol, Jonathan Houghton Lindsay
Using The Suprachiasmatic Nucleus As A Model System To Assess Tolerance And Withdrawal To Alcohol, Jonathan Houghton Lindsay
Doctoral Dissertations
Alcohol abuse induces many disorders including depression, metabolic syndrome, and sleep disturbances. The strong link between alcohol abuse and sleep problems, along with the close connection between sleep and circadian rhythms, led us to investigate ethanol’s effects on the circadian clock. Previous work has shown that acute ethanol blocks photic phase shifts in vivo and glutamatergic phase shifts in vitro. However, neural systems become tolerant to ethanol across different timeframes. Despite both ethanol tolerance and ethanol withdrawal syndrome being listed as criteria for developing alcohol use disorders, little is known about how ethanol tolerance and withdrawal induced hyperexcitability develop and …
A Grounded Theory Inquiry Into Crying In Women Dealing With The Emotional Stress Of Personal Crisis, Mary Bess Griffith
A Grounded Theory Inquiry Into Crying In Women Dealing With The Emotional Stress Of Personal Crisis, Mary Bess Griffith
Doctoral Dissertations
The belief that crying leads to healing is so widely held and of such longstanding that many healthcare professionals—including nurses, physicians, psychiatrists, and psychologists—accept it as fact even though there is little substantiating scientific evidence. Crying is commonly believed to be an essential factor in restoring mind-body equilibrium after physical and/or emotional trauma has been experienced. If, as has been hypothesized by many scientists and healthcare practitioners, emotional crying is a biopsychosocial healing modality, then specifics of its therapeutic praxis, including limitations and ambiguities, should be incorporated into nursing education and practice. In this grounded theory study, the meaning and …

Ampk Activation By Zyflamend: A Novel Pathway Regulating Metabolism And Growth In Prostate Cancer, Amber Frances Macdonald
Ampk Activation By Zyflamend: A Novel Pathway Regulating Metabolism And Growth In Prostate Cancer, Amber Frances Macdonald
Masters Theses
Zyflamend, a select blend of 10 herbal extracts, effectively inhibits tumor growth using preclinical models of castrate-resistant prostate cancer (CR-PCa), mediated in part by activating AMPK, a master energy sensor of the cell. Currently, two predominant upstream kinases are known to phosphorylate/activate AMPK at Thr172: LKB1, a known tumor suppressor, and CaMKK2, a tumor promotor over-expressed in a number of cancers. Thus, the overall objective was to interrogate how Zyflamend activates AMPK and determine the roles of LKB1 and CaMKK2 in this activation, by targeting upstream mediators of both kinases ± Zyflamend using pharmacologic and molecular techniques in CWR22Rv1 (CR-PCa …
Effect Of Ultrasonication On The Physicochemical Properties Of Sorghum Kafirin And Evaluation Of Its Anti-Inflammatory Properties In Vitro, Andrew Cullen Sullivan
Effect Of Ultrasonication On The Physicochemical Properties Of Sorghum Kafirin And Evaluation Of Its Anti-Inflammatory Properties In Vitro, Andrew Cullen Sullivan
Masters Theses
Sorghum is one of the hardiest, most drought resistent cereal grains known to exist, providing the bulk of nutritional content for many semi-arid regions and developing countries throughout Africa and southwestern Asia. It contains dense nutritional value, but due to inhibition factors within the grain, much of these nutrients are indigestible. Access to these nutrients, which have shown to contain high contents of bioactive molecules linked to the decrease of prevalence of chronic disease, must then be facilitated before consumption. In sorghum, these molecules could include complex carbohydrates, proteins and polyphenols. The overall objective of this study was to determine …

Media Coverage Of Tennessee's Amendment 1, Hayley A. Brundige
Baker Scholar Projects
In 2014, Tennesseans went to the polls to vote on a controversial abortion amendment to the state constitution that was years in the making. Two organizations – Yes on 1 and No on One – spent millions of dollars on advertising to insert their rhetoric into the public debate and sway voter opinion. To some, Amendment 1 represented a chance for Tennesseans to take back control over abortion regulations in the state and protect women and girls. To others, the measure went too far and constituted unnecessary government interference into private decisions. For many, the issue set two deeply-held values …
The Effects Of Motivational Interviewing On Heart Failure Self-Care During Transitional Care In An Appalachian Population, Jennifer Lynn Mabry
The Effects Of Motivational Interviewing On Heart Failure Self-Care During Transitional Care In An Appalachian Population, Jennifer Lynn Mabry
Doctoral Dissertations
Research has shown that patients who are successfully engaged in self-care for a chronic illness have a higher quality of life and reduced hospitalizations than those who are not. According to the National Center for Health Statistics, transitional care in the home setting has seen a 51% increase in mortality over the last 15 years (Reeder et al., 2015). This finding contrasts with the reported decline in hospital readmissions for chronic illnesses. With the lack of agreement on best practices for patient discharge education, transitional care has proven to be a weakness in chronic illness care that requires further research. …
