A Risk-Informed Approach To Performing The Pre-Closure Safety Analysis For The Deep Borehole Disposal Of Radioactive Waste, Jennifer Elizabeth Leute

Nuclear Engineering ETDs

Deep borehole disposal is an emerging concept which involves disposing of radioactive

waste in boreholes several kilometers deep then backfilling to minimize radionuclide

transport and distribute weight. Unfortunately, little documentation exists on borehole

safety case development, especially for pre-closure operations. This study aims to close

this gap by proposing a graded approach matrix based on consequence, maturity, and

complexity. Two case studies are used to demonstrate this application: Hanford CsCl

capsules and spent PWR assemblies. Simulations are used to predict potential for dose

exposure, revealing CsCl capsules have a much higher potential for being above the 5

Modeling Mineral Redistribution In Biological Tissue Using Apple As An In Vitro Analogue, Daler Djuraev, Ali Algemsh, Halima Alazeb, Zeenia Ahmed

Publications and Research

This project aims to model mineral (ion) redistribution that occurs in human soft tissue after injury or mechanical/thermal stress. Because direct, repeatable in vivo measurements are difficult, we use apples as an in vitro analogue: their mineral content is relatively uniform and the tissue can be cut, dried, and repeatedly imaged under controlled conditions. Using X-ray imaging, we tracked how minerals in apple tissue move toward damaged regions immediately after cutting, and how subsequent drying at room temperature drives a redistribution toward the central core. We also observed that biological degradation (decay) alters mineral density over time, indicating that even …

Extending its analysis beyond Kingsley's experiences of exploration, this edition investigates the forces behind the book’s creation, including Kingsley’s intellectual development, her identity as an independent female traveler and writer, and …

Patient-Derived Ovarian Cancer Models Provide Insight Into Cancer Cell-Intrinsic And Immune Cell-Dependent Effects On Therapeutic Response, Parisa Nikeghbal

Biomedical Sciences ETDs

Ovarian cancer is the most lethal gynecologic malignancy, largely due to late diagnosis and resistance to chemotherapy. This dissertation applies patient-derived organoids (PDOs), xenograft-derived organoids (PDXOs), and humanized xenografts (huPDX) to investigate therapeutic responses and immune interactions. Organoids were shown to retain critical features of the original malignancy. Across platinum-sensitive, -resistant, and -refractory cases, both PDOs and PDXOs exhibited drug sensitivities that aligned with patients’ clinical classifications. Building on this foundation, a drug screen revealed novel strategies. Auranofin restored platinum sensitivity in Notch3-active models, afatinib broadly reduced viability, and adavosertib–gemcitabine and sorafenib–topotecan combinations produced synergy. Extending this work, immune interactions …

Graph Based Planning With Guarantees, Trazon Tyrik Jimerson

Mechanical Engineering ETDs

This thesis presents two graph-based methods with formal guarantees for motion planning and routing. First, the invariant-set motion planner (ISMP), which uses constraint admissible positive invariant (CAPI) sets of closed-loop dynamics, is adapted for spacecraft attitude planning to avoid moving keep-out zones. Contributions include time bounds for maneuvers via exponential stability, a single-stage reachability graph from one-step backward reachable CAPI sets, and its multi-stage expansion to certify node safety over time. Simulations verify safe attitude control with moving obstacles. Second, we formulate a convex optimization problem over a network for evacuation planning with operational constraints such as helicopter capacity and …

Design And Development Of Evacuated Photovoltaic-Thermal Systems For Efficient Cogeneration Of Heat And Electricity, Behnam Roshanzadeh

Mechanical Engineering ETDs

In conventional PV systems, most of the solar energy is dissipated into the environment as heat. Accordingly, hybrid Photovoltaic-thermal systems have been developed to utilize the waste heat from PV cells for various thermal applications. However, most PVT systems suffer from low thermal performance compared to solar thermal collectors, as the absorber plate in PVT systems is partially or fully covered by PV cells. This dissertation focuses on improving the thermal performance of PVT systems by introducing the evacuated PVT systems.

An evacuated-tube PVT system was designed and simulated for domestic hot water supply. The evacuated-tube PVT system demonstrated 40% …

Efficacy Of Oil And Gas Production Site Remediation In U.S. Arid/Semi-Arid Regions, Skye Ontiveros

Architecture and Planning ETDs

Oil and gas production (OGP) is expanding, paralleled by its polluting leaks and spills (LS), and outpaced by its waste. This raises the question: Does remediation of LS occur effectively when needed to protect the environment and public, particularly in major producing regions like arid/semi-arid regions (ASAR), which account for approximately 72% of US oil and 42% of gas production? To answer, a review of the eight largest national remedial laws, sourced from the Code of Federal Regulations (CFR), identified 14 OGP exemptions for remedial determinants (RDs): factors affecting remedial frequency and efficacy (e.g. LS monitoring and chemical disclosure). An …

Nuclear Engineering ETDs

Several studies have been done on the effects of twisted tubes in heat exchangers, including the correlations that relate the flow parameters to the heat transfer and pressure drop experienced. These studies are new, with the earliest being performed in 1982. As such, there are many correlations covering only certain flow parameters and geometrical configurations such as the Reynolds number and modified Froude number.

This thesis attempts to cover flow regimes and tube geometries not yet studied and yield correlations. Data are gathered from heat exchangers featuring twisted tubes with water as the working fluid. It is noticed that the …

Stress During Adolescence: A Characterization Of Anxiety-Like Behavior, And The Mrna Expression Of Neuroimmune Factors, Clock And Stress Genes In Corticolimbic Areas., Annette Fernandez Oropeza, Annette K. Fernandez Oropeza

Biomedical Sciences ETDs

Adolescence represents a critical window of frontal cortex (FC) maturation and corticolimbic circuit refinement that supports stress and emotion regulation. Disruption of these processes by early-life insults such as prenatal alcohol exposure (PAE) or adolescent stress increases vulnerability to anxiety and mood disorders, in part through circadian–immune dysregulation. The circadian transcription factor Bmal1 and the proinflammatory cytokine tumor necrosis factor-alpha (TNFα) have emerged as key regulators of neuroimmune signaling and synaptic communication, yet their interactions across developmental risk contexts remain poorly understood. This dissertation examined the effects of mild adolescent isolation stress, with and without PAE, on anxiety-like behaviors and …

Corporeality In Choral Sound: Elements Of Consonant Diction Shaping Pre-Expressive Presence, Perceived Clarity, And Expression In English-Language Choral Music, Addison Walton

Dissertations, 2020-current

The genesis of this project stems from a lived experience performing with a professional choir, whose sung physical shaping of the English language—its crystalline clarity, profound expressivity, and the pre-expressive elements inherent in the delivery—was deeply and viscerally compelling. This overwhelming reaction was in response to their bodies; specifically, the sound their bodies produced that evoked a sense of corporeality, or tangible bodily presence. There was beauty to be found in the way their mouths physically formed the language, both within and removed from the semantic context.

This study sought to acknowledge those fleeting, pre-expressive moments in choral music and …

Irregularities In The Dynamics Of Large Networks: Cases On Social Networks And The Internet, Dheeman Saha, Abdullah Mueen, Shuang Luan, Afsah Anwar, Yangsun Hong

Computer Science ETDs

Dynamic networks capture evolving relationships among entities, and irregularities in their behavior often signal significant events. This dissertation investigates such irregularities across social and infrastructural networks. First, we analyze Twitter (prior to its rebranding to X) to characterize influencers, introducing a follower-overlap similarity measure that identifies micro-influencers beyond content-based methods.

We then examine election-related irregularities by comparing suspended and non-suspended accounts during the 2020 U.S. presidential election, revealing behavioral patterns linked to misinformation and coordinated manipulation.

Next, we develop an algorithm to infer post-specific diffusion networks, reconstructing who-saw-from-whom pathways for tweets at scale. This method uncovers structural differences in diffusion …

The Pathophysiological Role Of Mitochondrial Acid-Sensing Ion Channel 1a In Hypoxic Pulmonary Hypertension, Megan N. Tuineau

Biomedical Sciences ETDs

Pulmonary hypertension (PH) is characterized by increased pulmonary arterial constriction, pulmonary arterial remodeling, and right ventricular dysfunction. While metabolic and mitochondrial derangements are increasingly recognized as central pathogenic features, the underlying mechanisms and effectors are not yet fully understood. Acid-sensing ion channel 1a (ASIC1a) is a proton-gated cation channel involved in the development of chronic hypoxia (CH)-induced PH. ASIC1a represents a potential candidate involved in metabolic-mitochondrial dysfunction, as metabolic byproducts can act as ligands for ASIC1a. Additionally, ASIC1a has recently been identified as a mitochondrial ion channel involved in neuronal death following oxidative stress. Therefore, we hypothesize that ASIC1a functions …
