Molecular Dynamics Simulations Of Nano-Scale Impact Icing On Graphene Substrates, Amir Afshar Nov 2020

Molecular Dynamics Simulations Of Nano-Scale Impact Icing On Graphene Substrates, Amir Afshar

Theses and Dissertations

In the atmosphere in the height of 18000ft to 25000ft, there are some metastable droplets called supercooled liquid water in the temperature range of 0◦C to 40◦C. When these droplets impinge on the wings of an airplane, a very thin layer of ice is formed on the surface. This natural phenomenon calls “impact icing”. In this research, I studied the nanoscale impact icing on structured graphite surfaces, as the substrates at the atomistic scale using Molecular Dynamics (MD) simulations. This research focuses on the first steps of the development of a predictive multiscale strategy for molecular simulations of impact ice …

Evaluating The Effects Of Perceived Student Race On Preservice Teachers’ Perceptions Of Situation Severity And Requests For Student Assistance, Nashedra Barry Nov 2020

Evaluating The Effects Of Perceived Student Race On Preservice Teachers’ Perceptions Of Situation Severity And Requests For Student Assistance, Nashedra Barry

Theses and Dissertations

There is currently a gap in research related to the potential effects of student race on school consultation and teacher help seeking behavior. It is well documented in the existing research that racial/ethnic bias exists in education at many levels. These biases lead to negative systemic effects such as achievement gaps, disproportionality in discipline, and disproportionality in special education referrals. Biases can also have negative effects on classroom interactions between teachers and students. It seems plausible that if biases exist in other domains of education, that they may also exist in the school consultation process. The purpose of the current …

Investigations On Mechanisms Of Survival And Pathogenesis Of Mycobacterium Ulcerans In Polymicrobial Environments, Laxmi Dhungel Nov 2020

Investigations On Mechanisms Of Survival And Pathogenesis Of Mycobacterium Ulcerans In Polymicrobial Environments, Laxmi Dhungel

Theses and Dissertations

Buruli ulcer disease (BUD) remains a ‘mysterious disease’ due to the unknown mode of M. ulcerans transmission and pathogenesis. To understand these, it is important to determine the reservoir of the organism in its natural environments, and stress response and interactions of M. ulcerans in its natural niche and during infection of a host. The major virulence factor of M. ulcerans is mycolactone, a lipid cytotoxin that is encoded on a giant plasmid pMUM001. Genetic analysis suggests that plasmid pMUM001 was acquired by M. ulcerans during evolution from its progenitor, M. marinum. Coincidental evolution of virulence hypothesis suggests that many …
