Animal Experiment (Rabbit) To Demonstrate Changes In Trabecular Bone Mechanical Properties Over Time Using Finite Element Analysis., Shuo Yang 1974-

Electronic Theses and Dissertations

Decreased strength of trabecular bone is a direct effect of osteoporosis, which can be evaluated by finite element analysis. However, computational limitations have restricted previous trabecular bone analyses primarily to the linear domain. In addition, previous work was largely invasive and the corresponding finite element models were typically homogeneous. Nonlinear heterogeneous finite element analysis was used to calculate trabecular bone apparent strength directly from in vivo micro computational tomography (micro-CT) scans. Through a series of validation experiments, it was shown that this nonlinear modeling is more accurate in evaluating trabecular bone mechanics in osteoporosis than previous work. A parameter driven …

China's globalism promotes a version of Western neoliberalism, including tropes such as efficiency, individuality, and freedom, to underwrite inequality, consumerism, and masking of surplus labor/value. While an ostensible boon for China's marginalized, China's globalism continues to increase the gap between wealthy and poor. Chapter One introduces the project with an overview of theoretical and disciplinary responses to globalization. This chapter demonstrates how the discourse of transnational capital supports consumerism, competition, and simultaneous "universality/difference" worldwide. Chapter Two offers a rhetorical …

The Effect Of Modular Tapered Fluted Stems On Proximal Stress Shielding In The Human Femur., Justin Steve Conway

Electronic Theses and Dissertations

Modular hip implants are currently being used in total hip arthroplasty revision procedures because it is common to have little or no bone left in the proximal region of the femur and it is difficult to accurately size implants based off of radiographs or other medical imaging techniques. The effect of modular systems using tapered fluted stems on proximal stress shielding in the human femur is the focus of this study. Seven modular implants were press-fit into seven femurs, where there was little or no contact between the modular body and the test femur. Finally, hydroxyapatite bone cement was added …

Seasonal Territoriality In The Carolina Wren, Thryothorus Ludovicianus, To Visual And Vocal Stimuli., Mark Allen Dunaway

Electronic Theses and Dissertations

Carolina Wrens, Thryothorus ludovicianus, are permanent residents throughout their range. They form pair bonds at a young age, maintain these bonds for multiple years, and defend feeding/breeding territories year round. Male Carolina Wrens use songs in territorial defense and have been shown to countersing regularly to both neighbors and intruders. They use various song characteristics to determine the location of another bird and whether its territory has been invaded.

Wrens often approach playbacks silently in apparent searching behavior. In some cases, birds will investigate the playback but fail to countersing. I wanted to determine whether or not wrens would …

Positioning Guglielmo Marconi's Wireless : A Rhetorical Analysis Of An Early Twentieth-Century Technology., Aaron Antonio Toscano 1976-

Electronic Theses and Dissertations

This dissertation is a rhetorical analysis of Guglielmo Marconi's wireless. Texts surrounding the invention reveal intersections between technology and society and communicate information about the wireless through tropes of progress. The wireless was seen as a monumental early twentieth-century technology that would change the world by extending communication potential. This dissertation demonstrates that the wireless was created rhetorically before it existed as a black-box technology. Marconi's technical texts, popular press articles, and F. T. Marinetti's reinscriptions are discourses where the wireless existed rhetorically. To borrow Charles Bazerman's definition, the rhetoric of technology deals with the ideology surrounding "objects of the …

Regulation Of Angiogenic Factors By Pituitary Tumor Transforming Gene (Pttg) In Tumorigenesis., Mohammad Tariq Malik

Electronic Theses and Dissertations

Pituitary tumor transforming gene ( PTTG ), also known as securing, is a novel oncogene that is expressed at high levels in most of the tumors analyzed to date. Overexpression of PTTG in mouse fibroblast(NIH 3T3) cells increases cell proliferation, induces cellular transformation and promotes tumor formation in nude mice. PTTG is a multi-domain and multifunction protein. Some functions of PTTG include inhibition of pre-mature sister chromatid separation, activation of transcription of c-myc oncogene, cell cycle regulation, and DNA repair. In some cancers such as thyroid, pituitary, esophageal, and colorectal tumors, high PTTG expression correlates with metastasis and poor prognosis. …

Besides having a high ratio of power to weight and flexible control of movement, it also exhibits many analogical behaviors to natural skeletal muscle, which makes them the ideal candidate for applications of anthropomorphic robotic systems. In this dissertation, a new phenomenological model of pneumatic muscle developed in the Human Sensory Feedback Laboratory at Wright Patterson Air Force Base is investigated. The closed loop stability of a one-link planar arm actuated by two pneumatic muscles using linear …

Using Auditory Evoked Brain Responses To Detect Anxious Vulnerabilities In Neonates., Kyle William Harvison

Electronic Theses and Dissertations

Anxiety disorders are prevalent in both adult and child populations, and are associated with significant economic and psychosocial costs. There are clearly familial patterns of transmission within the anxiety disorders, and the inherited risk is likely a non-specific vulnerability toward negative affect, with a biological-environmental interaction leading to specific manifestations within the anxiety disorders. Among the vulnerabilities toward anxiety may be information processing biases that predispose individuals to be more vigilant to novelty, processes that may be specifically associated with the right cerebral hemisphere. The current study utilized auditory event related potentials (ERPs) to explore the degree to which such …

Conjugative Transfer Pathways Of High-Level Mupirocin Resistance And Conjugative Transfer Genes In Staphylococcus., Danielle Barnard

Electronic Theses and Dissertations

To combat widespread infections caused by Staphylococcus aureus, mupirocin was introduced at the Veterans Affairs Medical Center, Mountain Home, Tennessee. Soon after introduction, high-level mupirocin-resistance emerged. The rapid emergence was hypothesized to be due to conjugative transfer of the mupA resistance gene from S. epidermidis to S. aureus. Results have shown that transfer of high-level mupirocin-resistance from S. aureus donors commonly occurs. However, transfer from naturally-occurring S. epidermidis donors was not attainable. Staphylococcus epidermidis transconjugants, however, were capable of serving as donors. Further examination of non-transmissibility included PCR analysis of conjugative transfer genes (tra genes) in capable …
