Examining Metabolism in Seagrass Meadows: Trends in Respiration and Non-Dissolved Gas Ebullition

Ieva Juska
Seagrass meadows provide many valuable ecosystem services, including carbon sequestration and storage of ‘blue carbon’. Enhancing carbon cycling through seagrass restoration can thus act as a nature-based solution for climate change, as these ecosystems naturally remove carbon dioxide from the atmosphere through their high rates of productivity. Estimated metabolic values such as Gross Primary Productivity (GPP), Respiration (R), and Net Ecosystem Metabolism (NEM) are used in quantifying in situ carbon sequestration in seagrass meadows and...

Compton Polarimetry for Neutral Weak Form Factor Measurements in 208Pb and 48Ca

Allison Zec
Atomic nuclei contain a number of protons and neutrons. Most heavy nuclei contain more neutrons than protons in order to remain stable. The nuclear proton distribution can be measured via elastic scattering of charged particles, but the neutron distribution remains poorly constrained. Nuclear structure theory also predicts a "neutron skin" ΔRnp where the mean radii of neutrons in the nucleus exceeds that of protons. Two experiments were run in 2019 and 2020 to measure the...

Identification of MHC-Associated Peptides and Phosphopeptides Presented in Various Diseased Cells by Tandem Mass Spectrometry

Xi Peng
Major histocompatibility complex (MHC) class I and II molecules are involved in the presentation of antigens to T cells, which can initiate an immune response upon recognition of abnormal peptide sequences and modifications. Specifically, phosphopeptides resulting from aberrantly increased protein phosphorylation in cancer are proposed as potential cancer-specific targets for developing novel immunotherapeutic treatments. However, it remains as a challenge to accurately identify these peptide sequences and to localize modification sites due to factors including...

Brass rank and gold rings : class, race, gender, and kinship within the Army community

Margaret Cecchine Harrell
Under traditional United States military system, officers were married men whose wives were expected to perform considerable unpaid labor, while enlisted men were assumed to be young unmarried men. To the extent that enlisted men, even the more senior enlisted personnel, were married, their wives and families were not generally acknowledged or supported by the Army; and they were separated from the officers' families by a considerable barrier of social class. In contrast, officers' wives...

Leveraging Proteomic Strategies to Analyze Post-Translational Modifications and Membrane Proteins

Maria Panepinto
This dissertation details three projects that apply tandem mass spectrometry to analyze purified proteins. There are three strategies that can be used to approach proteomic analysis: intact, limited digestion, and traditional digestion. All three of these projects are unified in that at least two of these strategies was required to achieve their goal. This dissertation demonstrates that these approaches are much more powerful and provide more information in combination than they do alone. The first...

All Y'All: Queering Southernness in Recent US Fiction

Heidi Siegrist
“All y’all” is redundant, but it describes a greater inclusiveness than “y’all” might accommodate. The South has long been considered the nation’s “queer” region; and yet it has also been considered a space inhospitable to queer life. Even so, popular interest in “the South” has long centered on ideas of otherness and backwardness; affective states of alienation and loss; and failure to adapt to, or refusal to participate in, the mainstream—the same preoccupations of major...

Place-Based Racial History to Inform Just Design

Bethany Gordon
Enhanced designs of the built environment are particularly urgent for frontline communities, who experience the “first and worst” of climate change. A climate adaptation approach that prioritizes need-based distributive justice, the allocation of resources to meet the basic conditions necessary for continued community existence, may empower frontline communities in the resource allocation process. Need-based distributive justice is often viewed as a supplement to other universal principles of distributive justice, such as merit — the allocation...

Ethics Training: Cultivating an Ethical Engineer Identity

Elaine Englehardt, Michael Pritchard, Kingsley Reeves, Grisselle Centeno, Michelle Hughes-Miller & Susan LeFrancois
There is limited research regarding the impact of current engineering ethics programs on the development of engineers. Indeed, most of the literature on this topic does not discuss ethics insofar as it functions as a part of how engineers regard their identify as engineers. Our 4-year NSF funded project directly addresses this oversight by assessing the impact of integrating engineering ethics education with student internships. This is being conducted jointly at Florida Polytechnic University (FPU)...

Resistance of Neisseria gonorrhoeae to nutritional immunity protein-mediated zinc limitation during epithelial infection

Jocelyn Ray
Neisseria gonorrhoeae (Gc) is an obligate human pathogen that infects mucosal epithelia to cause the common sexually-transmitted infection (STI) gonorrhea, and antimicrobial-resistant Gc is an urgent public health threat. Gonorrhea has the potential to cause serious sequelae when untreated, especially in women, who may be asymptomatic and unaware that they are infected. The initial site of infection of the female reproductive tract is usually the cervix. In order to establish infection, Gc must attach to...

The role of Notch signaling in regulating neural stem cell quiescence and termination during development

Chhavi Sood
Multipotent cells called neural stem cells (NSCs) proliferate to produce a functional adult neural circuitry and maintain tissue homeostasis during development and in adulthood. NSCs can divide either symmetrically to increase stem cell numbers or asymmetrically to produce different types of progenies. During development, most NSCs terminate their proliferation and neurogenesis becomes restricted and in the adult tissue, NSCs are maintained in a state of quiescence in neurogenic niches. The NSC proliferation versus quiescence decisions...

Method for Thoracic Injury Risk Function Development for Human Body Models

Shubham Kulkarni
Introduction: In recent years, finite element human body models (FE-HBMs or HBMs) have been developed as an evaluation tool for restraint system and safety assessment in virtual simulations. However, for HBMs to be truly useful as a tool, standardized methods need to be developed for translating the outputs from HBM simulations into predicted risk of injury. An important body region of interest for such standardization is the thorax. Although the thorax was one of the...
