Veils of Oppression: An Exploration of Paul Fitzsimmons Eve and His Impact on Enslaved Black Women\u27s Lives
Get PDFThis thesis contributes to the ongoing study of gender, race, and medicine in the United States, focusing on Dr. Paul Fitzsimmons Eve and his practices. By examining the experiences of enslaved black women subjected to his surgical procedures and experiments, medical racism, harm, and exploitation become visible
A Computational Study on Impact Performance of Concrete Barriers for Protecting Transportation Assets
Get PDFHighway safety is a major concern as roads accommodate increasing numbers of vehicles, including large trucks and tractor-trailers. Concrete barriers are commonly used along highways and bridges to prevent accidents by redirecting vehicles and protecting important structures like bridge piers. However, their effectiveness depends on how well they withstand vehicle impacts, how they perform after being damaged in previous crashes, and how they protect bridge piers when space is limited. This research examines these issues using advanced computer simulations to better understand barrier performance and improve roadway safety.
The first part of this study reviews how researchers and engineers use computer simulations to test concrete barriers instead of relying solely on costly and time-consuming full-scale crash tests. These simulations performed using finite element analysis software, help predict how barriers behave in different impact conditions and guide safer barrier designs.
The second part of the study focuses on how barriers hold up after multiple impacts. In real-world scenarios, a barrier may be hit more than once before being repaired or replaced. This research simulates crashes with large trucks striking barriers in sequence and finds that barriers may weaken significantly after an initial impact, increasing the risk of failure in subsequent crashes. The findings help transportation agencies determine when a barrier is still safe to use and when it should be repaired or replaced.
The third part examines how barriers can better protect bridge piers from large vehicle impacts, especially in space-limited areas. Barriers placed too close or attached to piers may transfer impact forces directly to the structure, increasing the risk of damage, while barriers placed too far away may fail to fully prevent vehicle intrusion. This study explores how barrier height, placement, and spacing affect their ability to shield bridge piers, leading to recommendations for improving national bridge safety guidelines.
By advancing the understanding of barrier performance in real-world crash conditions, this research helps engineers, policymakers, and transportation agencies improve road safety standards. The findings contribute to developing stronger, more effective barriers that enhance highway and bridge safety for all road users
Reliability of Novel Morphological Features of the Auditory Brainstem Response
Get PDFPure-tone audiometry can detect hearing loss but does not determine specific site-of-lesion. It is not sensitive to many disorders, especially neural disorders that impact hearin
Effects of Self-Control Variables on Nicotine Vaping in a Pre-Clinical Model
Get PDFTobacco use is the leading cause of preventable death in the United States, and nicotine compounds in tobacco products perpetuate this issue (Reitsma et al., 2021; United States Department of Health and Human Services [USDHHS], 2014). Although nicotine use began to decline along with the use of cigarettes, nicotine consumption has started to increase dramatically since the introduction of electronic cigarettes and vaping
Tiny Fixers, Big Impact: Can This Bacteria Replace Your Fertilizer?
Get PDFIf cultured on a media lacking available nitrogen, then our isolated bacteria will continue to proliferate through the assimilation of nitrogen available in the air
Exercise and Its Effect on the NAD Content of Tissues in Niacin Deficient Mice With Free Choice Running Wheels
Get PDFNicotinamide adenine dinucleotide (NAD) content of tissues decreases over time during aging. In our study, we determine if physical exercise has an effect on the NAD content in tissues of transgenic mice that were NAD- deficient because of vitamin B3-free diet. The underlying hypothesis of this study is that exercise can prevent NAD decline and maintain higher level of NAD in tissue. A potential impact of this study is that exercise could be used to lengthen healthspan compared to individuals not participating in any physical exercise
Are Logan Police Officers Equipped to Deal With Domestic Disturbances Effectively
Get PDFIf officers do not have proper training to deal with domestic violence, then they become ineffective tools to help the public. We as the public need officers to keep the peace but if there is improper training they are ineffectiv
Anti-Transgender Legislation and State Legislature Demographics
Get PDFIntroduction
Anti-transgender legislation has been introduced in state legislatures at exponentially increasing rates over the past five years. 85 bills were introduced in 2020, climbing rapidly to 692 in 2024. As of April 3, 2025, 830 bills have already been introduced in 2025.*
Studies show that this legislation is harmful to the LGBTQ+ community, especially transgender youth, even if bills are only introduced. This project seeks to understand the demographic factors of legislatures introducing and passing this legislation to assist advocates in electing legislators who will fight this legislation
Who Supports Democracy in the Post-Arab Spring Maghreb?
Get PDFBackground
During the Arab Spring in 2011, youth became the backbone of protests and a force for democratic change. Particularly in Tunisia – the heart of the Spring– youth had a dominant role in starting protests and toppling regimes. Extant literature\u27s mixed findings on wealth’s positive association with democratization processes suggest democracy’s support depends on public opinion and age. Building off fieldwork and interviews with students in Tunisia, my study focuses on economic development and its impact on public opinion.

Fast Computation of the Friction Stir Welding Process With Model Order Reduction
Get PDFFriction stir welding (FSW) is a manufacturing process used to join materials through intense heat and pressure. To better understand and optimize this FSW process, mathematical models incorporating non-Newtonian Navier-stokes equations for large plastic deformation and heat equation for the heat transfer are used to simulate the FSW process. However, solving these coupled and nonlinear equations with high accuracy requires significant computational power and time. This thesis has applied model order reduction, more precisely the Proper Orthogonal Decomposition (POD) and Discrete Empirical Interpolation Method (DEIM), to efficiently solve the FSW system in low-dimensional space. Slight modifications are made regarding the POD and DEIM treatment: (1) preconditioner matrices are used on the original full model system before applied the POD and DEIM to avoid large condition number for the POD and DEIM low-dimensional coefficient matrices, and (2) indicator matrices are used in the full model system to deal with different regions and used to generate the nonlinear data for the DEIM. The results show that this approach dramatically reduces computation time, e.g., over 250 times smaller for the DEIM compared with full model, while maintaining accuracy. This makes simulations of friction stir welding more accessible and easily combined with other machine learning techniques in future study
