Polarization Properties Of Millisecond Pulsars: Astrophysical Interpretations And Applications, Haley Megan Wahl

Graduate Theses, Dissertations, and Problem Reports (ETD)

Pulsars are some of the most extreme objects in the universe; their small yet incredibly predictable spin periods coupled with their strong magnetic fields make them ideal laboratories for study. Not only are they interesting objects themselves, but they can also help us probe different astrophysical environments, such as the interstellar magnetic field and the solar corona.

These stars are highly polarized, and that polarization comes into play in various fields of pulsar physics (such as constraining models of pulsar emission), but obtaining that polarization information can be difficult, as the polarization properties of the light can change as the …

Modeling And Optimization Of A Novel Chilled Ammonia Absorption Process And Amine-Appended Metal-Organic Frameworks For Co2 Capture, Ryan Keith Hughes

Graduate Theses, Dissertations, and Problem Reports (ETD)

Post-combustion capture is one of the leading technologies for CO₂ abatement from anthropogenic sources which have contributed significantly to the rise of atmospheric greenhouse gases. Specifically, solvent-based capture post-combustion processes are the industry standard but can suffer drawbacks such as high energy penalties and corrosion. In this work, two possible improvements are investigated which have been recently proposed in the literature. The first is aqueous ammonia as a capture solvent which has been shown to have several advantages including, but not limited to, a lower regeneration energy. The second is a novel solid sorbent, an amine-appended metal-organic framework (MOF). …

A Multi-Method Examination Of The Effects Of Students’ Unconscious Biases On Student Evaluations Of Instructors, Brittany M. Kowalski

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this dissertation, I complete three studies to evaluate potential reactions to target role congruity, especially gender role congruity, through an examination of Student Evaluations of Instructors (SEIs). Target role congruity refers to assessments an observer makes of whether or not the various roles a target person fills “fit” with one another. For example, a woman surgeon may be perceived as being in an incongruent role due to the masculine characteristics associated with the occupation and the continued dominance of men in the field. Researchers utilizing congruity theories has shown that both women and men in roles that are incongruent …

Cross-Kingdom Interactions Shape Soil Biogeochemistry In Natural And Agricultural Ecosystems, Jennifer Lynne Kane

Graduate Theses, Dissertations, and Problem Reports (ETD)

Microorganisms influence life on earth in innumerable ways, including in medical, industrial, environmental, and agricultural contexts. Given the increasingly apparent consequences of climate warming, interest in how to better predict and manage Earth’s carbon sinks has never been greater. Soil, the largest terrestrial carbon sink, harbors an incredibly taxonomically and functionally diverse microbial community. These soil-dwelling microbes govern the fate of soil carbon and nutrients by cycling organic matter as they live, grow, and die. It has only been relatively recently that technological advancement has allowed for in-depth surveys of the vast diversity of soil microbes. High throughput analytical capabilities …

We perform a systematic study of the ear features and propose a taxonomy for them. Also, we investigate the …

Electronic Structure Of Early Transition Metal Complexes Supported By Pyridine Polypyrrolide Ligands, Dylan Connor Leary

Graduate Theses, Dissertations, and Problem Reports (ETD)

A thorough study of photoluminescent molecules involving the pyridine polypyrrole(ide) ligand platform has been conducted. A detailed analysis on speciation of the proligand H₂(^MesPDP^Ph) (H₂^MesPDP^Ph = 2,6-bis(5-mesityl-3-phenyl-1H-pyrrol-2-yl)-pyridine) and its dilithium salt Li₂(^MesPDP^Ph) revealed temperature- and solvent-dependent effects. These molecules, along with the hydrochloric acid adduct [H₃(^MesPDP^Ph)]Cl were found to exhibit short-lived photoluminescence in both tetrahydrofuran and benzene solution. These findings confirm the hypothesis that heavy-atom involvement is crucial for the favorable photophysical properties observed for the Zr(PDP)_{2 …}

Love At First Profile: An Experiment Exploring If Previously Incarcerated Individuals Are Less Desirable While Online Dating, Carina L. Perrone

Graduate Theses, Dissertations, and Problem Reports (ETD)

Incarceration is a rapidly increasing occurrence in the United States with more than 1.4 million people incarcerated and more than 2 million on some form of restricted confinement. While men are incarcerated at a much higher rate than women, women are still at a steady incline of incarceration as well. Also, people of color disproportionately make up a large number of those incarcerated while accounting for a small percentage of the general population. Previous research on people who have been incarcerated focuses on it affects education, employment, and marriage. Little research has attempted to explore how incarceration effects dating, a …

Tumor-Targeted Ph-Sensitive Manganese Oxide Nanoparticle For Enhanced Detection Of Breast Cancer Using Mri, Celia Martinez De La Torre

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the United States, approximately 287,850 new cases of invasive breast cancer will be diagnosed, and over 43,000 women will die because of it in 2022. Currently, mammography is the gold standard for breast cancer surveillance. Although this detection technique is relatively cheap and fast, it misses about 1 in 5 breast cancers in younger women with dense breast tissue, causing a delay in treatment. Compared to mammography, magnetic resonance imaging (MRI) has superior soft-tissue contrast that elucidates structural differences within soft tissue to detect more breast cancers. However, MRI still misses

NEMO particles were produced by synthesizing manganese oxide …

With the push toward lower emissions from transportation vehicles for a cleaner future, the United States of America (US) has incentivized the conversion from the use of conventional fossil fuel, diesel, to lower carbon alternatives. With the increased potential for the use of alternative fuels, an investigation is warranted to understand the differences. This …

The Musashi Rna Binding Proteins Are Regulators Of Alternative Splicing And Protein Expression In Photoreceptor Cells, Fatimah Kh. Matalkah

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Musashi (Msi) family of RNA binding proteins consists of two paralogs, Msi1 and Msi2, that are highly conserved across species. The two paralogs have emerged as factors that promote stem cell proliferation by post-transcriptionally regulating translation. In addition to their expression in stem cells, the Musashi proteins are also expressed in postmitotic neurons, including the photoreceptor cells. The Musashi proteins have been observed to maintain high expression levels in the postmitotic photoreceptors within the eye of both invertebrates and vertebrates. These observations suggest an additional role in the maintenance of terminally differentiated neurons.

Building upon these observations, we investigated …

Decentralized Cooperative Localization For Multi-Robot Systems In Challenging Environments, Eduardo Gutierrez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Multi-robot systems provide more adaptability and robustness than conventional single-robot systems. This is because they have the ability to achieve partial completion of a task in the presence of failures due to the intrinsic inclusion of non-single-point failure. In multi-robot systems, cooperative localization refers to the use of relative measurements to improve the group’s overall localization performance. While centralized architectures in the system may result in unfeasible cases due to the high cost of computation and communication, decentralized methods distribute the computation among the robots in the group, enhancing the performance and making the system more efficient. Achieving a reliable …

Elucidating The Proteasomal Regulatory Mechanism Of Proteasome Activator Pa28Γ /Regγ, Taylor Ann Thomas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Virtually all cellular processes are precisely regulated by the proteasome which is the primary enzyme responsible for the degradation of misfolded, damaged, or no longer necessary soluble proteins. To prevent any untimely degradation of these target protein substrates and protect the cell, the proteasome is tightly regulated via adaptor proteins, known as proteasomal regulators. There are many classes of proteasomal regulators each with their own unique structures, functions, and effects on protein degradation through the proteasome. One such class is the 11S family of proteasomal regulators which are also referred to as PA26/28, or REG. The 11S family are ATP-independent …

Photophysics And Photochemistry Enabled By Ligand-To-Metal-Charge-Transfer: Unusual Carbon-Carbon Bond Formation At A Zirconium Center, P. Minh N. Do

Graduate Theses, Dissertations, and Problem Reports (ETD)

Six Group 4 metallocene derivatives of group 4 incorporating a redox active benzene-1,2-thiolate ligand (bdt) were prepared. These complexes were characterized using one- and two-dimensional nuclear magnetic resonance (NMR) spectroscopy. Additionally, X-ray crystallographic analyses of these complexes, with the exception of Cp₂Zrbdt (Cp = cyclopentadienyl), reveal C_2v symmetric structure in the solid-state. All species display electronic absorption bands that are ligand-to-metal charge transfer (LMCT) in character well into the visible region. Spectroscopic data combine with time dependent-density functional theory calculations showed fluctuation in solution which promotes non-radiative energy loss and leads to the absence of emission in …

Synthesis, Characterization, And Activation Of Pyridine Dipyrrolide Supported Vanadium-Nitrogen Multiple Bonds, Jordan Cruz Martinez

Graduate Theses, Dissertations, and Problem Reports (ETD)

The chemistry of coordination complexes of vanadium supported by pyridine di-pyrrolide pincer ligands was probed via the synthesis and investigation of a variety of compounds from the trivalent starting material, (^MesPDP^Ph)VCl(thf)₂. Under reducing conditions and subsequent addition of terpyridine, a redox transfer series (1-, 0, 1+) stemming from the neutral product (^MesPDP^Ph)V(terpy) was isolated and characterized by X-ray crystallography. The precise bond lengths, in conjunction with bulk magnetic susceptibility, allowed for a detailed study of the redox non-innocence of polypyridyl ligands in these systems.

Probabilistic Space Weather Modeling And Forecasting For The Challenge Of Orbital Drag In Space Traffic Management, Richard J. Licata Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the modern space age, private companies are crowding the already-congested low Earth orbit (LEO) regime with small satellite mega constellations. With over 25,000 objects larger than 10 cm already in LEO, this rapid expansion is forcing us towards the enterprise on Space Traffic Management (STM). STM is an operational effort that focuses on conjunction assessment and collision avoidance between objects. While the equations of motion for objects in orbit are well-known, there are many uncertain parameters that result in the uncertainty of an object's future position. The force that the atmosphere exerts on satellite - known as drag - …

First Responders’ Assumptions: An Exploration Of Emergency Medical Technicians’ Secondary Traumatic Stress And Perceptions Of Substance Users, Glenn Noble

Graduate Theses, Dissertations, and Problem Reports (ETD)

Emergency medical technicians (EMT) and firefighters respond to critical incidents and provide emergent care. As the opioid crisis continues and drug overdose rates increase, first responders administer first aid to substance users, including Naloxone, more frequently. This study examined the influence of repeated exposure to drug-related critical incidents and provision of care to substance users on EMTs' and firefighters' secondary traumatic stress (STS) level, world assumptions, and substance use stigma. First responders' world assumptions, STS, burnout, and exposure to drug-related overdoses were analyzed for their power in predicting substance use stigma. Results suggest that occupational burnout, rather than STS, is …

Assessment Of Electronic Cigarette User Terminology And Knowledge Using Mixed Methods, Margaret G. Childers-Kakos

Graduate Theses, Dissertations, and Problem Reports (ETD)

Electronic cigarettes (ECIGs) have evolved rapidly over the past several years, and it is unclear if terminology used when assessing ECIG knowledge and use behavior has objective and well-understood definitions between consumers, as well as between consumers and the research community. The purpose of this study was to use semi-structured interviews to obtain a better understanding of ECIGs from the perspective of regular ECIG users. One-hour interviews consisted of both open- and closed-ended questions. Questions probed the terminology used by participants to describe both individual and combination device features, as well as ECIG use behaviors. Qualitative data was used to …

“Where Did Your Christ Come From”? Exploring The Significance And Prevalence Of The White Jesus Phenomenon Among Black Baptist Women And Men, Stephanie Marshelle House-Niamke

Graduate Theses, Dissertations, and Problem Reports (ETD)

Berger's theory of religion and world construction fails to consider the critical issue of power and who is allowed to construct their own reality and thus, does not adequately capture the experience of Black Christians and the Black religious experience. I use White Jesus as a case study to analyze this process. Though the White Jesus phenomenon has been more readily explored in theological and historical fields, very little sociological research discusses this phenomenon. I argue that a Europeanized Jesus has had harmful sociocultural effects on Black Christians and Black people, in the form of cultural trauma. Yet, the White …

Influences Of Disrupted Circadian Rhythms On Stroke Outcome, Jennifer A. Liu

Graduate Theses, Dissertations, and Problem Reports (ETD)

The circadian system is composed of a subset of temporal oscillators that function through a transcriptional and post-translational molecular and functional negative feedback loop cycling approximately every 24 hours. The central clock located in the suprachiasmatic nucleus is responsible for entrainment using light as the key timekeeper (zeitgeber); it is responsible for synchronizing and optimizing physiological behavior and function to the environment. Exogenous information, such as day length and light-dark cycles, provide critical temporal cues for adjusting to environmental conditions. Proper alignment to natural light dark cycles and circadian rhythms is optimal for vital health, fitness, and survival in organisms. …

Structure-Dependent Characterizations Of Multistationarity In Mass-Action Reaction Networks, Galyna Voitiuk

Graduate Theses, Dissertations, and Problem Reports (ETD)

This project explores a topic in Chemical Reaction Network Theory. We analyze networks with one dimensional stoichiometric subspace using mass-action kinetics. For these types of networks, we study how the capacity for multiple positive equilibria and multiple positive nondegenerate equilibria can be determined using Euclidian embedded graphs. Our work adds to the catalog of the class of reaction networks with one-dimensional stoichiometric subspace answering in the affirmative a conjecture posed by Joshi and Shiu: Conjecture 0.1 (Question 6.1 [26]). A reaction network with one-dimensional stoichiometric subspace and more than one source complex has the capacity for multistationarity if and only …
