Light Scattering Studies Of Hyaluronate Solutions, Tim Mcnutt

Theses

The results of light scattering experiments on aqueous solutions of sodium hyaluronate are reported. Hyaluronate is an important component of the eye lens vitreous and many other connective tissues. The dependence of the light scattering on sodium hyaluronate molecular weight is studied and compared with a renormalization group model of polymer solution free energies. The results for the molecular weight and concentration ranges investigated fall on or near a universal scaling relationship provided by the model. This work extends previous comparisons of polyelectrolyte solutions to the same scaling relation.

An Analytical Method To Detect And Quantify Ll-37 In An In Vitro Co-Culture Of Activated Thp-1 Cells And Staphylococcus Aureus, Staphylococcus Epidermidis, And Pseudomonas Aeruginosa, Victoria Hunter

Graduate Theses and Dissertations

Healthcare-associated infections (HCAIs) affect 1.7 million hospitalized patients each year, resulting in over 98,000 deaths and anywhere from $28.4 to $45 billion in treatment costs. Furthermore, it has been established that more than 80% of these infections are caused by biofilms While HCAIs can be bacterial, viral, fungal, or parasitic, there are between 12 and 17 species cause 80 to 87% of all HCAIs. Among the most commonly isolated microorganisms are Pseudomonas aeruginosa (P. aeruginosa) and Staphylococcus aureus (S. aureus). Thus, biofilms are of importance not only due to their prevalence in HCAIs but also due to the increased antibiotic …

Genomic Analysis And Metabolic Potential Of Myxobacteria, Hanan Albataineh

Electronic Theses and Dissertations

Myxobacteria are known for their large genomes that bestow them with a distinct lifestyle that is characterized by fruiting body formation, gliding motility, social interactions, predation, and secondary metabolite production. The powerful combination of whole-genome sequencing and bioinformatics-driven analysis of sequence data has delivered unexpected insights into myxobacterial microbial communities. We applied these two approaches to investigate the chemical space and biosynthetic potential of myxobacteria. Mining different myxobacterial genomes for biosynthetic gene clusters led us to the discovery of a cryptic acyl-homoserine lactone (AHL) synthase encoded in the genome of the myxobacterium Archangium gephyra. Bioinformatic analysis of this AHL synthase …

Evaluating The Effects Of Thermal Cycling On Bone (Cold-Blooded Vs Warm-Blooded), Parker Reed Brewster

Electronic Theses and Dissertations

Thermal cycling, a global threat that is increasingly becoming more real, is a stressing event that can drastically change material properties. Thermal cycling can be used for material strengthening and optimization, but more often than that, thermal cycling is a nuisance that weakens the integrity of structures and coatings. To understand and build better designs that resist the effects of thermal cycling, we look to nature. Though warm-blooded animals regulate their body temperatures within an exceptionally tight range, cold-blooded animals experience relatively extreme temperature fluctuations, and oftentimes, in less than a 5-hour time period. In other words, cold-blooded animals experience …

The Self Compassionate Side Of Awe: The Relationship Between Awe And Self-Compassion Via Self-Diminishment And Connectedness, Rachael Marie Cavallaro

Electronic Theses and Dissertations

Given that having a self-compassionate attitude is linked to positive psychological functioning, it is important to identify factors that promote self-compassion. Several self-transcendent experiences and emotions, which perceptually blur the lines between the self and others, predict self-compassion. Awe, a mixed-valance emotion defined by vastness and need for accommodation, seemed a likely candidate to promote self-compassion, as it is also a self- transcendent emotion with intra and interpersonal functions (e.g., increased humility, openness, and connection) that theory and empirical research has linked to self-compassion. Thus, we hypothesized that awe would promote self-compassion both directly and indirectly via boosted feelings of …

Design And Fabrication Of Additively Manufactured Arm Cast Using Topology Optimization, Tereza Janatova

Electronic Theses and Dissertations

The traditional approach to casting non-operative arm fractures involves fully covering a large portion of the forearm, often including a portion of the palm. The use of gypsum plaster and plaster materials often results in cutaneous problems or in more severe cases swelling, pressure sores, or deep vein thrombosis. Other disadvantages include the weight, time it takes to harden, or the damage in contact with water. The objective of the project is to create a durable but breathable custom-made design for an arm brace that will replace the traditional solutions by overcoming their disadvantages. Several research groups and companies provide …

Empirical Essays In Law And Economics, Bright Addiyia Osei

Electronic Theses and Dissertations

I examine the effect of laws and policies regulating the use of drugs onthe decision making of economic agents. In the first paper, I estimate the effects of legalized recreational marijuana on entry into the foster-care system by exploiting state-level variation in legalization and its timing, I estimate that legalization decreases foster-care placements by at least 10%, with larger effects in years after legalization. I find even larger decreases in admissions due to parental drug and alcohol abuse, implying that substitution towards marijuana from other substances is an important part of how legalization affects admissions. I find similar effects for …

Emotion Regulation In Migraine, Tracy Protti

Electronic Theses and Dissertations

Migraine is the third most common medical condition across the globe and a leading cause of years lived with disability due to its considerable burden. The burden is further compounded by the high prevalence of psychological comorbidities and the influence of other psychological factors on functioning. Examinations of migraine within the fear-avoidance model suggest that fear of pain (FOP) promotes maladaptive avoidance and escape behaviors, which contribute to headache-related disability. Limited research demonstrates that those with migraine engage in avoidant emotion-regulation (ER) strategies but has overlooked ER abilities beyond acceptance. The current study aimed to investigate ER in individuals with …

Protein Redesign And De Novo Design Approaches To Create Artificial Nickel-Dependent Metalloenzymes, Dhanashree Selvan

Electronic Theses and Dissertations

Energy crisis, energy demand and climate change are the major challenges of this century. As we face these challenges, it’s important that we depend on alternate energy forms like renewable energy sources and at the same devise ways to tackle the greenhouse effect. Therefore, it is important to move towards a carbon neutral energy economy where we can convert atmospheric carbon dioxide back into organic carbon and depend on clean energy sources like Hydrogen. These energy concerns can be tackled well if we understand the role of enzymes responsible for various biological reactions.Metals play a variety of unexpected roles in …

Bridging Souths: Interdisciplinarity And Knowledge Production In Southern Studies, Matthew David Streets

Electronic Theses and Dissertations

This thesis examines the viability of southern studies, a regional studies project on the study of the U.S. South, as an academic field of study and institutionalized site of multi-, inter-, and transdisciplinary knowledge production. Southern studies has undergone numerous turns and paradigm shifts since its institutionalization in the 1970s. These ontological, epistemological, and methodological developments have reoriented the objectives of interdisciplinary knowledge production. Despite the present permeability of disciplinary boundaries, the institutional structure and its racial, capitalist, and disciplinary hierarchies hinder communication and collaboration across disciplines and fields and between the “ivory tower” and “real world.” Understanding the impact …

Do Individuals With Functional Gastrointestinal Symptoms Experience Emotions Differently? An Examination Of Emotional Responding During A Series Of Emotion Induction Tasks, Sara Witcraft

Electronic Theses and Dissertations

Functional gastrointestinal disorders (FGIDs) are disorders of the brain-gut axis characterized by physiological and emotional disturbances, including heightened comorbidity with psychiatric disorders. Individuals with FGIDs experience difficulties with emotional processing, including the awareness, identification, and regulation of emotions. Although emotional processing is implicated in the maintenance and exacerbation of FGID pathology, literature examining these associations is limited. The current study aimed to enhance understanding of the emotional processing of individuals with FGIDs. We recruited individuals with and without FGID symptoms and examined the: (1) association between gastrointestinal distress and psychopathology; (2) association between gastrointestinal distress and emotional and physiological responsivity; …

English Language: The Subtle Force Behind The Demise Ofmozambican Higher Education Academic’S Aspirations, Ricardo Pinto Mario Covele, Patricio V. Langa, Patrick Swanzy

Journal of Comparative & International Higher Education

It is contended that Lusophone universities are to a certain degree deprived access to American and European scholarships in the 21st century. We examine the validity of this statement, focusing on the barriers scholars often face when accessing scholarships using English. To explore the constraints English language imposes on Mozambican lecturers pursuing international scholarships, the study employed qualitative research methods using structured interviews. The sample of interviewees included university lecturers from Eduardo Mondlane University. The discussions of the study were guided by two dominant themes: language coloniality and academic oppression (Lack of accessibility). Participants had their unique experiences while attempting …

When Experts Become Novices: A Mixed-Methods Exploration Of International Scholars’ Experiences At A Us University, Masha Krsmanovic

Journal of Comparative & International Higher Education

The experiences of international scholars in the United States who are part of short-term or exchange programs remain vastly under-investigated compared to their full-time, tenure-track, and tenured peers. Guided by Blau’s (1964) social exchange theory, this study investigated professional and social experiences of exchange scholars at a large public research university in the southeast United States. A mixed-method exploration was conducted through surveys and interviews with international scholars who participated in an exchange program in the spring of 2020.

Exploring Generativity In Young Adults: A Grounded Theory Study, Addison Sellon

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

Generativity expresses one’s level of care and concern for the next generation (Erikson, 1950, 1963). Initially established as a middle adulthood phenomenon, generativity has long been rooted in a middle adulthood framework both conceptually and through its psychometric dimensions. However, many studies have found generativity to be present in other stages of life, particularly young adulthood. This then raised the question of whether the traditional model used for generativity’s manifestation represents young adults’ experiences. This study sought further to explore generativity’s manifestation in a way that is specific to young adults. Applying traditional grounded theory techniques, the present research reanalyzed …

Impacts Of Physical Parameterization Schemes And Soil Moisture Initialization On Boundary Layer Evolution In The Weather Research And Forecasting (Wrf) Model, Grace Cutting

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Numerical weather prediction (NWP) models have become a necessary addition to the atmospheric research community over the last several decades, and atmospheric modeling has been used internationally for numerous operational and research purposes. NWP models contain a vast number of combinations of physical and dynamical parameterization schemes; however, they are not always accurate in forecasting weather phenomena at a particular location, as different combinations of parameterization schemes represent differing conditions. Weather Research and Forecasting (WRF) model simulations were run to explore which of the commonly used planetary boundary layer (PBL) schemes best represented upper-air data (as well as PBL evolution) …

A Latent Class Analysis Of Personality Traits With Educational Attainment, Tyler Minter

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The five-factor model of personality (extraversion, agreeableness, conscientiousness, neuroticism, openness to experience) is an empirically based personality model that has been utilized in multiple psychological assessments. Recent works have found Block & Block’s (1980) three personality profiles (resilient, overcontrolled, undercontrolled) within the context of the five-factor model. This study performed a latent class analysis using a short FFM assessment from the SAPA project, a free online personality test. The intention of this study was to replicate the three personality profiles within the five-factor model. Four latent classes were included in the final solution. Two of the three personality profiles emerged …
