Characterization Of Rare-Earth Doped Thermal Barrier Coatings For Phosphor Thermometry, Quentin Fouliard

Electronic Theses and Dissertations

Thermal Barrier Coatings have been extensively used to protect and insulate the metallic components in turbine engines from extreme environments to achieve higher turbine inlet temperatures, resulting in an increase in combined engine cycle efficiency, lowering NOx emissions and fuel consumption. Additionally, as the major failure mechanisms determining lifetime are thermally activated during engine operation, uncertainty in temperature measurements affects lifetime prediction. Early detection of Thermal Barrier Coatings spallation symptoms, associated with local delamination induced temperature changes, can reduce forced engine outages. Further improvements are envisioned with the development of more reliable measurement techniques. For this purpose, Phosphor Thermometry has …

Subjective Measures Of Implicit Categorization Learning, Audrey Zlatkin

Electronic Theses and Dissertations

The neuropsychological theory known as COVIS (COmpetition between Verbal and Implicit Systems) postulates that distinct brain systems compete during category learning. The explicit system involves conscious hypothesis testing about verbalizable rules, while the implicit system relies on procedural learning of rules that are difficult to verbalize. Specifically from a behavioral approach, COVIS has been supported through demonstrating empirical dissociations between explicit and implicit learning tasks. The current studies were designed to gain deeper understanding of implicit category learning through the implementation of a subjective measure of awareness, Meta d', which until now has not been validated within a COVIS framework. …

The Psychosocial Effects Of Solid Organ Transplantation On Living Donors: A Literature Review, Christopher G. Evans

Chronic pain is often treated with analgesics of varying potency, some with serious adverse side effects if used over a long period of time. Exploring the effectiveness of therapies other than medication to treat chronic pain is important to decrease or eliminate the amount to pain medication taken for chronic pain. Hydrotherapy is one therapy that may improve the pain experience for those with chronic pain. A literature search was conducted using the …

Nursing Interventions For Intradialtyic Hypotension: Using Blood Volume Monitoring Guided Ultrafiltration, Suzette S. Cedeno

Honors Undergraduate Theses

Background: Intradialytic hypotension is a potential complication experienced by patients with end-stage renal disease who receive hemodialysis. This complication occurs during the dialysis treatment in 15-30% of all treatments. The multiple comorbidities that exist in hemodialysis patients predispose them to recurrent intradialytic hypotension episodes. Recurrent intradialytic hypotensive episodes can result in negative short-term and long-term clinical consequences. Short-term consequences include complications such as ischemic events (e.g., heart attacks, strokes), clotting of patient dialysis access, or heart rhythm abnormalities. Long-term consequences include end-organ damage, increased cardiovascular morbidity, and a higher mortality rate. Problem Statement: Available nursing interventions used to treat intradialytic …

Metabolic Effects Of 17a-Estradiol Are Growth Hormone Independent And Sex Specific, Silvana Sidhom

Electronic Theses and Dissertations

Aging is a major risk factor for metabolic syndromes and type two diabetes. With growing elderly populations worldwide and increasing incidence of age-related diseases there is a great need to develop pharmacological interventions that would delay aging and protect from age-related diseases. 17-alpha estradiol (17α-E2) is an epimer of the primary female sex hormone estradiol and has been shown to extend lifespan and downregulate markers of age-related metabolic dysfunction in male mice. Because 17α-E2 does not induce feminization in males it holds potential as a novel therapeutic in humans for age-related metabolic dysfunction. Importantly, we have previously shown that 17α-E2 …

Identification And Functional Characterization Of A Long Non-Coding Rna Associated With Prostate Cancer, Md Faqrul Hasan

Electronic Theses and Dissertations

Prostate cancer is the most common cancer in men in the western world. Although early stage prostate cancer is treatable late stage, more specifically, metastatic and drug resistant prostate cancers are mostly incurable. The failure of current treatments obligates the research community to explore novel areas in prostate cancer biology and find better therapeutic targets. Emerging evidences show that non-coding RNAs specifically long non-coding RNAs (lncRNAs) play regulatory roles in various cellular processes and are frequently dysregulated in cancer including prostate cancer. These aberrantly expressed lncRNAs mostly with unexplored genetic information may drive cancer progression. Previous studies done in our …

Teachers' Perceptions Of Safety Regarding School Shootings, Megan Olive

Electronic Theses and Dissertations

As a result of high media attention surrounding school shootings in recent years, it may appear that American public schools are becoming dangerous places (Schildkraut & Elsass, 2016; Elsass, Schildkraut, & Stafford, 2016; Toppo, 2013). Though schools remain to be one of the safest locations for children, various safety measures are discussed and implemented in schools to combat this perceived problem and ensure the safety of school campuses. Discussions of best safety practices spikes directly following a school shooting event from relevant parties, such as school administration, law enforcement agencies, parents, and students, (Crawford & Burns, 2015; Chrusciel, Wolfe, Hansen, …

Development Of A Functional Testing Platform For The Sensory Segment Of The Neuromuscular Reflex Arc, Alisha Colon

Electronic Theses and Dissertations

Investigations of human biology and disease have been hindered by the use of animal models. The information obtained from such studies often results in clinically irrelevant results and drug trial failures. Additionally, several governing bodies have been formulating legislation to move away from animal models and toward more ethical and efficient testing platforms for drug discovery and cosmetic research. As an answer to these issues, "body-on-a-chip" systems have been a rapidly developing field which easily recapitulates in vivo functionality, providing a more relevant, repeatable, and ethical testing platform to better predict biology. These systems can be used as human-based testing …

Approximate In-Memory Computing On Rerams, Salman Anwar Khokhar

Electronic Theses and Dissertations

Computing systems have seen tremendous growth over the past few decades in their capabilities, efficiency, and deployment use cases. This growth has been driven by progress in lithography techniques, improvement in synthesis tools, architectures and power management. However, there is a growing disparity between computing power and the demands on modern computing systems. The standard Von-Neuman architecture has separate data storage and data processing locations. Therefore, it suffers from a memory-processor communication bottleneck, which is commonly referred to as the 'memory wall'. The relatively slower progress in memory technology compared with processing units has continued to exacerbate the memory wall …

Biomass Density Based Adjustment Of Lidar-Derived Digital Elevation Models: A Machine Learning Approach, Khalid Abdelwahab
