As a violist, holding the viola is a lifetime issue because of the weight, and the variety of shapes and sizes of the instrument. These factors can cause more difficulty …

Nox Formation In Syngas/Air Combustion, Nazli Asgari

Theses and Dissertations

Syngas is a reliable energy source derived from the gasification of coal and other solid fuels. The feedstock type and the production process of syngas can affect the composition of syngas. Gas turbines utilizing high hydrogen content (HHC) fuels like syngas for power generation applications need to meet stringent pollutant emission standards, particularly with respect to nitrogen oxides (NOx). For gas turbine conditions, reliable experimental data, especially at high-pressure, is necessary for both generating accurate NOx prediction models and improving reaction pathways regarding the NOx chemistry. In this study, NOx formation in post-flame gases of syngas combustion at different conditions …

Role Of Mammary Microenvironment In Promoting Left-Right Differences In Tumor Progression, Metastasis, And Therapeutic Response, Huda Issa Atiya

Theses and Dissertations

Metastasis is the main cause of death in breast cancer patients; however, there are currently no treatments available to treat or prevent metastasis. This is in part because regulators of metastasis are not yet fully understood. Over the past century researchers began to study metastasis regulators by different hypotheses, such as the seed and soil hypothesis which focuses on studying the role of cancer cells, the seeds, and the tissue microenvironment, the soil, in regulating metastasis. Although lots of studies have focused on the microenvironment of metastatic sites and their roles in regulating metastasis, limited studies have focused on the …

The Effect Of Mindful Practices On The Independent Learning Process Of Third-Grade Montessori Students, E. Simone Mori

The Effects Of Modifiable Lifestyle Behaviors On Lipoprotein Particle Concentration And Size, Ryan R. Porter

Theses and Dissertations

Lipoprotein concentrations are well established biological markers associated with cardiovascular disease (CVD) risk. Recent research has placed great importance on the various functions of the different lipoprotein subfractions (small and large low-density lipoprotein particles [LDL-P]; small, medium and large high-density lipoprotein particles [HDL-P]). Modifiable lifestyle behaviors such as exercise, diet, and sleep have been shown to have direct effects on CVD risk, in part by altering blood lipid and lipoprotein profiles. The overall goal of this dissertation was to determine if specific modifiable lifestyle behaviors were associated with the concentration and size of lipoprotein subfractions.

Two studies, both utilizing a …

Regulation Of Cytoplasmic Dynein By Lis1 And Adenomatous Polyposis Coli, Timothy Joshua Hines

Theses and Dissertations

Cytoplasmic dynein 1 (dynein) is a microtubule motor that plays a role in mitosis, cell migration, and minus-end directed microtubule-based transport. The lissencephaly protein, Lis1, and its binding partner, Ndel1, are critical regulators of cytoplasmic dynein (Niethammer et al., 2000). In humans, haploinsufficiency of Lis1 leads to lissencephaly, a devastating developmental neurological disorder characterized by severe brain malformation, leading to cognitive and motor defects, and progressively worsening seizures (Dobyns et al., 1993). While Lis1 is known to play a role in regulating dynein-dependent functions such as neuronal migration and mitotic spindle orientation during development, the protein is still highly expressed …

State Specific Poverty Thresholds Adjusted For Cost Of Living Differences, Melissa Gentry

Theses and Dissertations

While poverty is undoubtedly one of the most widely used domestic indicators of social wellbeing, its measurement has a critical shortcoming. Using national poverty thresholds ignores the potential differences in the cost of living across states. States use the national poverty threshold when conducting poverty research and assessing community demographics. Theoretically price level differences between states could mean that, if poverty thresholds were adjusted for cost-of-living by state, the adjusted poverty rate could be different than the official poverty rate Using data specific to individual states that can be found in the Census Bureau’s American Community Survey, geographically specific thresholds …

How Do Health System Employees With Established Musculoskeletal Complaints Decide On Their Treatment Pathway? A Qualitative Approach, Noor Alshareef

Theses and Dissertations

Purpose: Non-pharmacologic treatment such as physical therapy (PT) are advocated for musculoskeletal pain for decreasing opioid use. Early access to PT has been shown to decrease costs and improve outcomes through direct access via self-referral. Although self-referral to PT is permitted in the majority of U.S states, health insurance coverage has been identified as a barrier preventing some patients with musculoskeletal complaints from using it. There are few studies examining patient factors related to early access to physical therapy via self-referral. The purpose of this study was to identify the factors outside of insurance that influence the choice to access …

A Comprehensive Reengineering Of The Hospital Emergency Triage System, Nicholas D. Boltin

Theses and Dissertations

Hospital emergency triage and specifically Mass Casualty Incidents (MCIs) are of major concern with regard to treatment and patient outcomes. Traditional emergency department triage models are oversimplified and often lead to over/under triaging of patients. Furthermore, triage models do not account for the full spectrum of different types of MCIs which often results in misclassification. In this thesis, we begin by looking at traditional triage models currently being used in hospital systems and identify several shortcomings of using these models within the context of a chemical related MCI. I will then move to describe a new approach to creating a …

Assessment Of An Educational Intervention To Increase Knowledge And Intention To Take Hpv Vaccine And Cervical Cancer Screening In Nigeria, Chigozie Anastacia Nkwonta

Theses and Dissertations

Nigeria has some of the highest rates of cervical cancer morbidity and mortality in sub-Saharan Africa. Both the human papillomavirus vaccine (HPV) and cervical screening are effective prevention strategies against both HPV infection and cervical cancer. Lack of awareness, limited knowledge, limited decision-making agency, lack of spousal support and stigma are barriers to uptake of these preventive measures. Given patriarchal structures and norms through which men control family resources and dominate decisions, male involvement in initiatives aimed at improving sexual and reproductive health is necessary. Community-based health education is an effective intervention to improve knowledge and reduce stigma. The aim …

Calibration Of An Accelerometer For Measurement Of Very Light Intensity Physical Activity In Children, Joseph S. Gorab

Theses and Dissertations

Obesity prevalence is continuing to rise in children in the United States. Decreased physical activity has long been thought to be a cause of this trend. As such, much of the accelerometer study has been focused on moderate to vigorous physical activity (MVPA). More recently, time spent in sedentary behavior has received much attention as well. There is an abundance of time spent in light intensity physical activity, and yet comparatively little focus has been placed on it in the field of accelerometer study. The purpose of this study was to generate an accelerometer count cut-point for the ActiGraph GT3X+ …
