Nonthermal Plasma Jet Efficacy On Candida Kefyr, Amber Marie Mattson Jackson

Electrical & Computer Engineering Theses & Dissertations

The inactivation abilities of a nonthermal plasma jet were investigated with the yeast C. kefyr, a pathogen with increasing importance in healthcare. The plasma is generated using a microhollow cathode discharge (MHCD) geometry operated with a DC voltage of 2 kV and a current of 30 mA using air as the operating gas at an airflow rate of 8 SLM. The plasma discharge approaches room temperature at a few mm away from the plasma jet allowing for the use on heat sensitive surfaces. Dry air and humid air were used as the operating gas to see if humidity plays …

Multilevel Analysis Of Physical Activity Among Us Adults Across Us Census Regions: The Role Of Environmental Contexts, Sariyamon Tiraphat

Health Services Research Dissertations

This study uses nationally representative data to explain the variation in physical activity among U.S. adults across four geographic regions of Northeast, Midwest, South, and West. The purpose of the study is to investigate whether environmental conditions inclusive of natural amenity, built environment, urbanization, crime, and social economic neighborhood are associated with physical activity and whether these associations are modified by geographic region. The study also investigates whether the influences of environmental contexts vary by subgroup and whether they are modified by geographic region. Determining regional factors that influence physical activity is essential to planning appropriate physical activity interventions.

Identification Of Persistent Long Range Interactions In GA95 And GB95 Through Thermal Unfolding Simulations, Milen Redai Tesfamariam

Chemistry & Biochemistry Theses & Dissertations

For over five decades, different experiments have been performed to research how proteins attain their native three dimensional structures. However, the folding problem continues to be a puzzle in modern science. The design of two proteins that have maximal sequence identity but different folds and functions is one method that is being used to study the relationship between protein structure and amino acid sequence. In particular, mutant proteins of Streptococcus protein G, G_A and G_B, have 95% sequence identity and a 3a helix fold and β4/a fold, respectively. Molecular dynamics simulations of G_A95 …

Alternative Therapy And Treatment Of Type 2 Diabetes, Carmine R. Grieco

Human Movement Studies & Special Education Theses & Dissertations

The rise in prevalence and incidence of type 2 diabetes mellitus (T2D) in the developing world continues unabated. Current treatment strategies, however, fall short of achieving optimal glycemic control. The aim of project I was to investigate the effect of an acute bout of a yogic breathing exercise on heart rate variability (HRV) in individuals with T2D. Project II was designed to assess the effectiveness of the neurohormone melatonin in lowering short- and long-term glucose levels, lipids and oxidative stress in T2D. Project III investigated the differential effects of two different styles of aerobic exercise on postprandial glycemia, mood and …

The Influence Of Interlimb Differences On Anterior Cruciate Ligament Injury Risk Factors In Female Collegiate Soccer Athletes, Eric Kevin Greska

Human Movement Studies & Special Education Theses & Dissertations

Female collegiate soccer athletes suffer anterior cruciate ligament (ACL) injuries at a rate of 0.31 per 1000 athlete-exposures, with 67% of injuries expected to be from a non-contact mechanism. As well, previous studies have demonstrated dissimilarity in non-contact ACL injuries relative to dominant and non-dominant legs; with the non-dominant leg being the involved side in 48-67% of reported incidents. The aim of this study was to examine lower extremity neuromechanics relative to leg dominance during an unanticipated sidestep cutting task, with differing states of fatigue and training.

Twenty female collegiate soccer players performed three valid trials for both the dominant …
