Characterization Of Nonequilibrium Plasma Discharge In High Water Vapor Concentration, Malik Mohammad Tahiyat

Theses and Dissertations

In recent years, plasma discharge in liquid medium has been a topic of immense interest. Theoretical efforts have been pursued to obtain insight on physicochemical processes being influenced due to trace water vapor either being present as residual or provided at a known concentration. However, studies on discharge at high vapor content are limited. In this study, discharge characteristics of plasma in high water concentration (> 90%) are investigated experimentally for a pressure range of 1 – 15 Torr to maximize vapor loading without condensation. Voltage-current characteristics were obtained over 0- 14 mA of current for each operating pressure; current …

In Vitro And In Vivo Studies Of Mediator Kinase, Lili Wang

Theses and Dissertations

This project addresses the molecular and in vivo activities of transcriptionregulating module CKM, comprised of CDK8 (or CDK19) kinases, Cyclin C, MED12 and MED13. Our lab has found that CDK8/19 potentiates NFkB-induced transcription. In this study, we confirmed that both CDK8 and CDK19 regulate gene expression in kinasedependent manner. CDK8 and CDK19 are not required for NFkB-induced transcription, which also occurs in HEK293-dKO (CDK8 and CDK19 double knockout) cells, but such transcription becomes CDK8/19-dependent upon re-expression of CDK8 or CDK19 in dKO. Surprisingly. pre-treatment with a CDK8/19 inhibitor decreases the effect of CDK8/19 on NFkB-induced transcription.

Comparative Assessment Of The Fate And Toxicity Of Chemically And Biologically Synthesized Silver Nanoparticles Toward Juvenile Clams, Mercenaria Mercenaria, Amar Yasser Al-Rshim

Theses and Dissertations

Engineered nanomaterials (ENMs) with unique nanoscale properties, including novel optical behavior and superparamagnetic, are continually being developed for biomedical and industrial applications. In specific biomedical applications, ENMs are surface-functionalized using polymers, proteins, and other stabilizing agents to facilitate their resistance to salt-induced aggregation. Since their colloidal stability in high ionic-strength matrices, functionalized ENMs are anticipated to be persistent aquatic contaminants. Despite their potential environmental significance, the persistence of surface-functionalized ENMs as individually stabilized nanoparticles in marine environments is largely unknown. Further, few studies have investigated the fundamental factors that influence ENMs uptake and fate/transport processes in ecologically susceptible aquatic biota, …

The Effect Of Emotional Intensity, Arousal, And Valence On Online Video Ad Sharing, Chang Won Choi

Theses and Dissertations

This dissertation examines the effect of emotional factors, such as pleasure, arousal, and intensity, on online video ad sharing. Previous studies found that the emotions evoked by online video ads could influence consumers’ ad sharing intentions. However, it remains uncertain which emotional factors trigger ad sharing behavior. Some researchers argue that positive or high-arousal emotions (e.g., excitement) exert greater influence on ad sharing than negative or low-arousal emotions (e.g., sadness). However, these studies do not explain why video ads that evoke low-arousal or unpleasant emotions are also widely shared on social media. Based on the theory of social sharing of …

Theses and Dissertations

This thesis looks at the development of youth hockey in North Carolina before the coming of the National Hockey League’s Carolina Hurricanes in 1997. Although the American South with its warm weather and lack of snow or ice seemed inhospitable to such a wintry sport, ice hockey found a niche in Charlotte, the Piedmont Triad, and the Research Triangle in the mid- to late- 20^th century through a combination of minor professional teams, local boosters, and northern transplants who all worked together to organize youth and amateur hockey associations as well as advocate for accessible ice rink facilities in …

Juveniles, Transferred Juveniles, And The Impact Of A Criminal Record On Employment Prospects In Adulthood: An Experimental Study, Joanna Daou

Theses and Dissertations

Previous research shows that a criminal record reduces an individual’s employability. The impact of a juvenile record on employability as a young adult, however, has rarely been examined, and no previous studies have estimated the effect of a criminal record when a juvenile was waived to the adult court. The current study seeks to fill these gaps in the literature using an experimental correspondence approach. The results of this research indicate that the effects of a delinquency record on employability for juveniles and young adults are comparable to the effects of a criminal record for adults.

Exploring Genetic Counselors’ Experiences, Language, And Discussion Of Consanguinity In Clinical Practice: A Multinational Perspective, Romy Isabel Fawaz

Theses and Dissertations

Consanguinity, defined as the degree of relationship between closely related individuals, is a widespread historical practice that is not specific to any one religion, population, or region of the world. Genetic counselors regularly ask whether a reproductive couple is consanguineous as part of the review of family history and risk assessment. Couples who are in consanguineous relationship may be subject to negative attitudes and stigma, potentially due to cultural differences and norms at a population level and these attitudes may interplay with questions, answers, and discussions around consanguinity. We hypothesized that genetic counselors may experience some level of discomfort discussing …

A Case Study Of Rural Southern Desegregation: How Black Students In A South Carolina Community Experienced Segregated Schooling And The Integration Process, Margo Mcdowell Gore

Theses and Dissertations

My purpose for this study is to shed light on how the African-American community in a small Southern rural community experienced segregated schools and the long school desegregation process. Conflicts over school integration in urban centers like Little Rock drew the media's attention, but how small communities beyond the glare of the media fared is less well understood and documented. Archival data and contemporary media coverage provide a timeline and context for the experiences of this Black community, and oral history interviews were collected and analyzed to document the range of desegregation experiences.

It’S An Old Song, But We’Re Gonna Sing It Again: The Myth Of Orpheus & Eurydice In Modern And Postmodern Theatrical Performance, Tiffani Brooks Hagan

Theses and Dissertations

Since theatre was established as an art form, productions have adapted myths into performance, creating an array of theatrical texts based on the oral practice of storytelling of ancient civilizations. This concept of adaptation, where playwrights draw from stories of the past in new works, has expanded in recent years to include new scholarship regarding the dramaturgy of theatrical adaptations and what it means to adapt a work, whether originally for theatre or not, into a text meant for theatrical performance. One such myth that has captivated audiences since its first recorded utilization has been the myth of Orpheus and …

“I Like A Fight”: Margaret Sanger And The First Birth Control Clinic In The United States, Rebecca Linnea Hall

Theses and Dissertations

It is nearly impossible to read the news in the United States today without hearing the name Planned Parenthood, but few Americans know about the origins of this organization. Margaret Sanger founded the Birth Control Clinical Research Bureau, the precursor to Planned Parenthood, in 1923, but this was not the first time she opened a clinic. In this paper, I assess Margaret Sanger’s 1916 opening of the Brownsville Clinic, the first birth control clinic in the United States, and the responses to this event from multiple historical perspectives. I use historical newspapers to demonstrate how popular media, legal experts, and …

Assessing Parental Satisfaction Of Current Fragile X Syndrome Resources Provided At Diagnosis, Megan Michalski

Theses and Dissertations

Diagnosis of a child with fragile X syndrome (FXS) is associated with parental anxiety. Existing literature recommends FXS resources, but there has not been a formal assessment of when parents learn about these resources, or their satisfaction with them. Studies have demonstrated negative feelings surrounding the diagnostic experience of FXS. This exploratory analysis assessed the gap in knowledge on parental satisfaction of the recommended resources from healthcare providers during the time of diagnosis. We predicted parents would not be satisfied with the way resources were presented to them. We discussed parental satisfaction or dissatisfaction, utility of the recommended resources, and …

Examining Parental Disclosure To Unaffected Siblings Of Children Diagnosed With Rett Syndrome, Rachel Nicely

Theses and Dissertations

Rett syndrome is a neurodevelopmental disorder that is inherited in an X-linked dominant manner due to pathogenic variants in the MECP2 gene that are almost always de novo. It is one of the most common causes of developmental delay and intellectual disability in females and occurs in about 1 in 10,000 females. While there is valuable literature surrounding the impact of a neurodevelopmental diagnosis on unaffected siblings, there are no articles about the impact of a disclosure of Rett syndrome to unaffected siblings and the needs of parents during this disclosure.

Concurrent Identification, Characterization, And Reconstruction Of Protein Structure And Mixed-Mode Dynamics From Rdc Data Using Redcraft, Hanin Rafiq Omar

Theses and Dissertations

A complete understanding of the structure-function relationship of proteins requires an analysis of their dynamic behaviors and the static structure. However, all current approaches to studying dynamics in proteins have their shortcomings. A conceptually attractive and alternative approach simultaneously characterizes a protein's structure and its intrinsic dynamics⁠. Ideally, such an approach could solely rely on RDC data-carrying both structural and dynamical information. The major bottleneck in utilizing RDC data in recent years has been attributed to a lack of RDC analysis tools capable of extracting the pertinent information embedded within this complex data source.

Here we present a comprehensive strategy …
