Unseen Warriors: A Phenomenological Study Of Female Veterans' Post Military Experiences In Central Texas, Natasha D. Smith

Doctoral Dissertations and Projects

The purpose of this phenomenological study was to describe female veterans' post-military experiences in Central Texas. Female veterans faced challenges post military service, including reintegrating into society, seeking resources through veteran and community programs, maintaining overall well-being, building relationships, and establishing their identities as veterans. Although programs and services were implemented to address barriers such as the lack of gender-specific healthcare, difficulties navigating community support systems, limited information about resources, and persistent social stigmas continued to exist. The goal of this phenomenological study was to understand female veterans’ lived experiences by using Alfred Schuetz’s Homecoming theory and Nancy Schlossberg’s Transition …

Multivariable Optimal Control For Hemodialysis: A Physiologically-Grounded Simulation Study, Redemtus Heru Tjahjana, Ratna Herdiana, Zani Anjani H.S.M. Rafsanjani, Yogi Ahmad Erlangga

All Works

This study introduces a novel multivariable optimal control framework for hemodialysis, which uniquely integrates five physiological states (blood urea concentration, fluid volume, blood pressure, electrolytes, and hemoglobin) with three clinically adjustable inputs (ultrafiltration rate, blood flow, and dialysate composition). By employing the limited-memory Broyden-Fletcher-Goldfarb-Shanno-B (L-BFGS-B) algorithm with patient-specific box constraints, the model enforces patient-specific physiological safety limits while dynamically balancing clinical targets. Numerical simulations demonstrate the stabilization of key parameters within ±5% of clinical benchmarks (e.g., KDIGO guidelines), though deviations in the hemodynamic responses underscore the need for adaptive control in real-world scenarios. Urea clearance trajectories align with efficacy patterns …

Curses & Versus: A Soldier's Life In Verse, Robert M. Haynes

A Tragedy And A Miracle: Trauma Medicine During The U.S. Civil War, Maxwell Bailey

Masters Theses

The Civil War, in many ways, hangs in the balance between the modern and premodern, with some historians calling it the first modern war, and others calling it the last pre-modern war. This historical dilemma extends to battlefield trauma care, where the modern and the archaic exist hand in hand. While the Civil War did not represent the birth of modern trauma care, it is certainly where modern American trauma care was conceived. The advancements in the medical field during this time prepared the way for germ theory to truly develop trauma care into a modern medical science. The groundwork …

The Regulars: Joseph Russell Knowland And The Roots Of Contemporary Republican Conservatism, Ron Cook

Doctoral Dissertations and Projects

The “regular” Republicans were the conservatives within the reform-dominated Republican Party at the dawn of the twentieth century. Heirs of the Republican “stalwarts” of the Gilded Age, they were the “machine,” “establishment,” and “old guard” Republicans in the Age of Theodore Roosevelt. Overall, they preferred traditional, “patron-based” and “service-oriented” party organization over the “issue-driven coalitions” of progressive reformers. Across most of the nineteenth century, American politics was rooted in simple party identity, and this traditional “politics of organization.” In the early twentieth century, however, progressives ushered in what historian Arthur Schlesinger, Jr., later called a “politics of ideology,” grounded not …

Physics & Astronomy Faculty Publications

Phase-change materials (PCMs) are essential for achieving tunability of metasurfaces. However, they frequently face limitations in the long-wave infrared range because of their lossy behavior. Here, we experimentally demonstrate a thermally tunable mid-infrared nanocavity resonance from coupled surface plasmon-phonon polaritons that are supported within a trilayer structure of metal-PCM layer-polar dielectric (Au-VO2-SiC). The top metal structures configure the Fabry-Perot cavity resonance near 840 cm−1 (11.9 µm), which is sensitively tunable and reversible with small changes in the VO2 refractive index ∆n near below its insulator-to-metal phase transition temperature where the loss is small. The maximum resonance shift of 7.7 cm−1 …

More than 1 in 4 men will undergo surgery for inguinal hernia, which is commonly associated with fibrotic degeneration of the lower abdominal muscle (LAM) in the groin region. Utilizing a male mouse model expressing the human aromatase gene (Aromhum), previous studies showed that locally produced estradiol acting via estrogen receptor α in LAM fibroblasts leads to fibrosis, myofiber atrophy, and hernia development. Here, we found that upregulation of progesterone receptor (PGR) in a LAM fibroblast population mediates this estrogenic effect. A PGR-selective progesterone antagonist in Aromhum mice decreased LAM fibrosis and atrophy, preventing hernia formation and stopping progression of …
