Exposing Evil: My Lai, The Media, And American Atrocities In Asia, 1941-1975, Joshua Caleb Greer

Master's Theses

In both the Pacific War against Japan from 1941 to 1945 and the Korean War from 1950 to 1953, United States combat troops—emboldened by a combat culture of dehumanization through racism and a military that enacted policies of attrition— committed atrocities against Asian soldiers and civilians. This trend continued into the Vietnam War unabated beginning in 1965. Incidents of atrocities committed by American troops overseas were not publicly discussed until the My Lai Massacre of 1968 was revealed to the American people in 1969. Once the massacre became a national news story published in outlets all over the country, American …

Flexure Strength Enhancement Study In Geopolymer Mortar, Victor Bivens

Master's Theses

This thesis includes the structural enhancement study on the flexible or semi-rigid design of geopolymer mortar (GPM) to address tensile cracking commonly found at the invert of reinforced concrete pipes. Concrete pipes are often subjected to harsh sewer conditions, which eventually spread to the reinforcement skeleton through the resulting cracks and corrode it to cause premature structural failure of the pipe. Therefore, this added flexibility to the pipes’ rigid material will not only serve to limit corrosion of the steel reinforcement within the pipes but will also aid in increasing the structural stability of the pipe in its entirety. The …

In the field of green chemistry, deep eutectic solvents (DES) have seen extensive use and research in the last two decades. Two carboxylic acid-choline chloride DESs were studied using experimental Fourier Transform Infrared Spectroscopy (FTIR) and computational Density Functional Theory (DFT). Geometry optimization, vibrational analysis, and assignment of vibrational frequencies were performed using B3LYP with a DNP basis set. The identified experimental FTIR peaks were found to be close to the calculated vibrations. Vibrations that would be impossible to identify and characterize using experimental methods were identified using DFT simulations. The shifts in wavenumber of FTIR vibrational peaks were studied …

Additive Manufacturing Of Binary Alloy A Phase Field Approach, Manoj Ghosh

Master's Theses

A phase-field approach is pursued to study the solidification of binary alloys, and equations governing the kinetics of the phase transformation are derived. The Ginzburg Landau equation and Cahn Hilliard equation were developed for the binary alloy phasefield model, considering both free energy minimization and conservation of mass. The analytical solutions for a dilute solution alloy are derived. For the thin interface limit, the correlation between the phase-field mobility and kinetic interface coefficient is developed, neglecting the diffusivity at the solid side. For a one-dimensional steady-state condition, along with the diffuse interface, the concentration profile is established as a function …

The Role Of Notch In Adipose-Derived Stem Cell Adipogenesis, Mengcheng Liu

Master's Theses

Obesity is the leading cause of chronic disease and has contributed to significant health problems and complications. In order to solve this increasingly serious social problem, it is particularly important to deepen the understanding of the biological causes of obesity. Obesity is the result of an increased mass of adipose tissue after excessive caloric intake, and adipogenesis is the main strategy through which the body increases the number of adipocytes. However, due to the lack of research, the current understanding of adipogenesis is not enough to yield results in the clinic.

The regulation of adipogenesis is complex, and the role …

The Megaprocessor As An Educational Tool Making The Abstract Concrete, Jonathon Beauregard Ii

Master's Theses

Computer architecture courses can be difficult for students to engage with and learn from. This is because, unlike most core courses for a computer science student, learning architecture is an abstract process. To address this, universities have implemented methods for teaching course material other than purely descriptive methods. This typically means using simulations to model some aspect of a CPU or FPGA (fieldprogrammable gate array) boards for hands-on experimentation in CPU design. However, there are issues with these tools. Simulations can only cover a few topics well, are prone to being abandoned, and introduce additional abstraction layers. FPGAs, while great …

Fast Asymptotic Algorithm For Real-Time Analysis Of Multivariate Systems And Signals By Directed Transfer Function And Partial Directed Coherence Measures Of Connectivity, Farnaz Rezaei

Master's Theses

Connectivity Granger-causality measures in the frequency domain, such as the Directed Transfer Function (DTF) and Partial Directed Coherence (PDC) and their variants, constitute a family 𝜙 of measures that stem from the modeling of multidimensional time series by multivariate autoregressive (MVAR) models. 𝜙 measures have become popular for evaluation of causal interactions in neuronal networks. Surrogate and asymptotic statistical analysis are the two most frequently used methods to quantify the statistical significance of the derived interactions, a critical step for validation of the results. Each method has its own pros and cons, with the recently published asymptotic methodology being faster. …

Local Oxidation Nanolithography Of Highly Oriented Pyrolytic Graphite, Zachary Swart

Master's Theses

In this thesis, the physical and electrical alterations caused by local oxidation nanolithography (LON) on highly oriented pyrolytic graphite (HOPG) are characterized. The LON is an atomic force microscopy (AFM) based technique that applies a positive bias to the sample relative to the AFM tip, leading to an electrochemical oxidation of the sample surface. If these physical and electrical alterations due to LON are well understood, this could yield a higher degree of control over tailoring the surface to become conductive, semiconductive or insulative in nature. The advantages of LON include room temperature operation in a non-vacuum environment, less steps …

The findings of the survey may be helpful in educating early childhood educators and bringing awareness to the misconceptions of stuttering.

Mindful Eating Behavior In Post Surgical Bariatric Patients, Megan Mabery Filer

Master's Theses

Emotional eating and binge-eating behavior in obese individuals and post-surgical bariatric patients are both linked to decreased ability to identify and cope with stress (Mitchell et al., 2016; Urquhart & Mihalynuk, 2011). In turn, obese patients who exhibit greater rates of stress-eating behavior show reductions in levels of mindfulness (Ouwens et al., 2015). The purpose of the study was to investigate the association between mindful eating component scores and selected weight loss outcomes in post-surgical bariatric patients.

Patients from a private bariatric clinic in Shreveport, Louisiana who underwent gastric sleeve or gastric bypass were invited to participate based on specific …

The English Quarrel Of Crown And Mitre: Ecclesiastical Liberties From Thomas Becket To Thomas More, 1170-1535, Matthew Flanders

Master's Theses

Two rival sets of law, canon and common, warred for supremacy in England from 1170-1535. Just as with any battle, casualties followed. Where Becket and Henry II fought the first battle in this clash of legal systems, More and Henry VIII would end it. The deaths of Thomas Becket in the twelfth century and Thomas More in the sixteenth century bear a striking resemblance, but while this superficially indicates a consistency of outcome, it also probes further into a consistency of conditions which made such an outcome likely. The difference between common and canon law, and the feud born therein, …

Optimization Of A Gfp Biosensor For The Discovery Of Novel Antibiotics, Drake Heinz

Master's Theses

In today’s world, there is an urgent need to discover novel antibiotics due to the rise of antibiotic resistance and the lack of new ones being approved. Building off of Hanson et al. and their reduction-oxidation sensitive green fluorescent protein (roGFP)(1), that we yeast codon optimized (2); I wanted to determine if I could create a real-time biosensor that has the ability to respond to ROS produced in the stress response triggered by antibiotics as a platform to identify novel antibiotics. To achieve this, I need to know if it will oligomerize in bacterial cytoplasm due to its two cysteines …

Dispersion Of Spherical Silicon Dioxide Nanoparticles In Poly(Styrene-B-Methyl Methacrylate) Diblock Copolymer Domains, Joshua C. Obinwa

Master's Theses

Polymer-nanoparticle hybrids are nanomaterials in which the unique properties of the nanosized structures can be precisely tuned by choosing an appropriate combination of the polymer and the nanoparticle. However, nanoparticle dispersion in a polymer is challenging due to the aggregation tendency of nanoparticles. To improve nanoparticle dispersion and control the location of nanoparticles in block copolymer assemblies, the nanoparticle surface is modified with surface ligands compatible with the block copolymer. In this thesis, hydroxyl-terminated poly(styrene-b-methyl methacrylate) (PS-b-PMMA) was utilized to functionalize the nanoparticle surface, covalently anchoring the hydroxylterminated end of the polymer onto the silicon dioxide nanoparticles. The silicon dioxide …

Electrochemical Detection Of Reactive Oxygen Species Via A Platinum Microelectrode Array, Victor M. Carriere Jr.

Master's Theses

Oxidative stress, an excess of endogenous or exogenous reactive oxygen species (ROS) in the body, is closely aligned with inflammatory responses. ROS such as hydrogen peroxide, superoxide, and radical hydroxyl ion serve essential functions in fighting infection, but chronic elevation of these species irreversibly damages cellular components. Given the central role of inflammation in a variety of diseases, including Alzheimer’s Disease, atherosclerosis, and rheumatoid arthritis, a low-cost, extracellular, non-invasive assay of ROS is needed.

This work reports the use of a platinum microelectrode array (Pt MEA)-based ceramic probe to detect time- and concentration-dependent variations in hydrogen peroxide (H2O2) production by …

Using Crispr-Cas9 As A Restriction Enzyme, Zack Crawley

Master's Theses

Restriction digests are a commonly utilized process for cleaving DNA at specific, but relatively common sites. Restriction enzymes have widespread use in DNA manipulation. CRISPR/Cas9 is a recently identified endonuclease which utilizes a customizable guide sequence to recognize and cut specific ~20 bp sites located in a DNA sequence. This preliminary research aimed to exploit the potential benefit of DNA restriction using the CRISPR/Cas9 procedure through alterations of different components involved in that system. We sought to refine existing CRISPR/Cas9 protocols and make a budget friendly, user-selectable CRISPR/Cas9 restriction digest protocol. The motivation for this research was to simplify and …

Examining Jack Kerouac's Role In The Beat Generation: Exploring Place In On The Road And The Dharma Bums, Kimberly Ann Tucker

Master's Theses

This examination of two of Jack Kerouac’s roman-á-clefs, On the Road (1957) and The Dharma Bums (1958), illuminates characteristics of Kerouac’s personality and writing that are often ignored by current criticism. I will attempt to enhance current Kerouac scholarship by further analyzing the physical and spiritual journeys that Kerouac’s personas experience in these novels, contrasting Kerouac’s personas’ development with that of his Beat Generation companions. Despite his admiration for Dean Moriarty (Neal Cassady) and Japhy Ryder (Gary Snyder), Kerouac does not present these individuals as American heroes. Indeed, Kerouac’s cynical narration suggests that these Beat characters cannot offer him the …
