Electronic Theses and Dissertations Archive

This dissertation discusses the of method development, optimization, and results of trace analysis of complex matrix samples of sodium hypochlorite solutions and environmental samples for contaminants using mass spectrometry bases methods. Sodium hypochlorite solutions are analyzed for the presence and concentration of haloacetic acids (HAAs). These HAAs are possible carcinogens to humans and regulated disinfectant byproducts. HAAs are the result of chlorination of water containing natural organic matter. The regulation of HAAs require the need to quantify and identify them as well as determine their sources. These sources could include formation by reactions or from contamination of treatment chemicals used …

Monte Carlo Generation Of Localized Particle Trajectories, Ivan Ahumada, James P. Edwards

School of Engineering, Computing and Mathematics

We introduce modifications to Monte Carlo simulations of the Feynman path integral that improve sampling of localized interactions. The algorithms generate trajectories in simple background potentials designed to concentrate them around the interaction region, reminiscent of importance sampling. This improves statistical sampling of the system and overcomes a long-time undersampling problem caused by the spatial diffusion inherent in Brownian motion. We prove the validity of our approach using previous analytic work on the distribution of values of the Wilson line over path integral trajectories and illustrate the improvements on some simple quantum mechanical systems.

Landau-Khalatnikov-Fradkin Gauge Transformations For The Propagator And Vertex In Qed And Qed2, James Edwards

School of Engineering, Computing and Mathematics

The non-perturbative Landau-Khalatnikov-Fradkin (LKF) transformations describe how Green functions in quantum field theory transform under a change in the photon field's linear covariant gauge parameter (denoted ξ). The transformations are framed most simply in coordinate space where they are multiplicative. They imply that information on gauge-dependent contributions from higher order diagrams in the perturbative series is contained in lower order contributions, which is useful in multi-loop calculations. We study the LKF transformations for the propagator and the vertex in both scalar and spinor QED, in some particular dimensions. A novelty of our work is to derive momentum-space integral representations of …

Modeling Of Functional Gene Regulation Through Machine Learning And Deep Learning Methods, Yuhao Chen

McKelvey School of Engineering Graduate Student Theses & Dissertations

Genes are specific sequences of nucleotides within the genome that undergo transcription to generate products that can diffuse throughout the cell. These gene products can take the form of either proteins or RNAs and play crucial roles in virtually all cellular functions, encompassing structural support, enzymatic activities, and signaling functions. An essential focus of contemporary biological research revolves around unraveling the functions of genes and their resulting products across different organisms. One primary means to conduct this research is through the regulation of gene expression. MicroRNAs (miRNAs), short single-stranded non-coding RNAs, play vital roles in gene expression regulation. Both computational …

A Quantitative Analysis Of Preschoolers’ English Consonant Spellings: Teasing Apart The Influences Of Frequencies, Phonetics, And Children’S Own Names, Jayde Elizabeth Homer

Arts & Sciences Graduate Student Theses and Dissertations

Before children are formally taught how to use letters to symbolize speech sounds, they know quite a bit about both. In three studies, I explored competing predictors of the quality of preschoolers’ spellings of the first phoneme of words—the first phoneme of a word being the most likely phoneme that a 3-, 4-, or 5-year-old attempts to spell. Frequency-based predictors included how common a word is or how often caregivers talk about certain letters. Phonetic-based predictors included segmenting the phonemes within a consonant cluster, how long a word is, the extent to which a letter name gives clues to the …

Following The Paper Trail: An Ethnoecology Of Hand Papermaking Traditions, James Ojascastro

Arts & Sciences Graduate Student Theses and Dissertations

Plants and their fibers have served as simple yet incredibly versatile raw materials for innovation for as long as humans have been on the planet. As the principal structural building blocks of plant cell walls, these hollow, cellulosic fibers have been co-opted by cultures around the world to meet diverse structural, absorptive, motile, and thermoregulatory needs—especially as textiles and paper. Despite (or because of!) this versatility, fibers vary considerably in physiology, and ethnographic records show that very few plant species have been chosen by tradition for use in fiber products. Surprisingly, no fiber ethnobotany study to date has attempted to …

Clawhammer: Vincent A. Witcher And Guerrilla Warfare In Civil War Southern Appalachia, Melanie Greer Storie

Doctoral Dissertations and Projects

Vincent A. Witcher, the subject of this dissertation, is largely unknown to Civil War historians. He is rarely mentioned, and when he is, it is primarily in connection with J.E.B. Stuart’s cavalry on the third day of the Battle of Gettysburg. Without the 1886 New York Times article and the resulting lawsuit, Witcher might have faded away as a historical footnote for his minor role at Gettysburg. However, this dissertation argues that his libel suit represents a microcosm of the complicated nature of guerrilla warfare during the Civil War. Through a lens of memory and regional history, the Witcher case …

Teacher Perceptions Of The Benefits Of Duets In Private Trumpet Lessons: A Qualitative Survey Study Of University Teachers In South Carolina, Todd Edison Jenkins

Doctoral Dissertations and Projects

While research exists surrounding trumpet pedagogy and utilizing duets in piano and string lessons, no studies currently focus on teachers’ perceptions of employing duets in private college trumpet lessons.

Tears Of Anger: The Compositional Function And Theology Of Imprecation In The Book Of Lamentations, Christopher William Peters

Doctoral Dissertations and Projects

Since the rise of redaction criticism as an area of scriptural exploration, much scholarship has centered on the composition of discrete biblical texts. Recently, research has expanded into treatments of canonical composition, determining how individual books unite into the larger Old Testament, New Testament, or biblical corpus. Given the lacuna surrounding these areas of research into the Old Testament Writings, this dissertation will explore compositional strategy and theology in the book of Lamentations. The thesis of this dissertation proposes that the imprecations of the book of Lamentations function textually as compositional seams to unite the poems into a cohesive whole …

How Successful Middle School Band Directors Display Supplemental Illustrations, Instructions, And Reference Material In Their Classrooms, Christopher Ryan Kristich

Doctoral Dissertations and Projects

Although presenting visual information is commonplace in a learning environment, many music educators could do this more effectively. This grounded theory project aimed to determine how successful middle school band directors display supplemental illustrations, instructions, and reference material in their classrooms. School administrators often require teachers to exhibit material related to the curriculum. Music educators are typically permitted autonomy with their wall displays if they maintain the educational parameters. Despite the potential benefits of displaying quality visual information, not all middle school band directors ensure that the auxiliary material presented in their room is relevant and constructive.

Retaining Students After Graduation With Biblical Servanthood, Carlos Henrique De Freitas

Doctoral Dissertations and Projects

This thesis addresses the inadequate understanding of the biblical concept of servanthood among high school students (grades 9-12) within the congregation of Macland Baptist Church in Powder Springs, Georgia. As a result of this problem, students gradually distance themselves from their faith, discontinue church attendance, and cease participating in church service activities. The thesis of this paper is that exposing these high school students to various dimensions of biblical servanthood will significantly impact their understanding of this concept. The underlying assumption posits that a profound understanding of biblical servanthood, coupled with knowledge and service opportunities, will cultivate Christlike character in …

Faculty, Staff and Students Publications

The prognosis of childhood medulloblastoma (MB) is often poor, and it usually requires aggressive therapy that adversely affects quality of life. microRNA-211 (miR-211) was previously identified as an important regulator of cells that descend from neural cells. Since medulloblastomas primarily affect cells with similar ontogeny, we investigated the role and mechanism of miR-211 in MB. Here we showed that miR-211 expression was highly downregulated in cell lines, PDXs, and clinical samples of different MB subgroups (SHH, Group 3, and Group 4) compared to normal cerebellum. miR-211 gene was ectopically expressed in transgenic cells from MB subgroups, and they were subjected …
