Capiz Reborn: Preserving And Enhancing Traditional Philippine Shellcraft, Destarte A. Prieto

Theses and Dissertations

The capiz shell is a thin, translucent exoskeleton of a mollusk found in the Philippine Sea. Traditionally, capiz shells were made into window panes and home decor, used so widely they became an iconic part of Philippine identity. Today, the influx of cheap, mass-produced merchandise threatens the capiz shell industry. To encourage renewed interest and sustainable revival of this long-standing industry, my research demonstrates new possibilities for the capiz shell.

In reconstituting cast-off bits and shell trimmings to form a new capiz biomaterial, my work is informed by the three traditional techniques used by Philippine capiz artisans—sewing, welding and bonding. …

Exploring The Role Of Senescence In Disuse-Induced Bone Loss And Therapeutic Strategies For Prevention, Steven J. Meas

Theses and Dissertations

Both age-related and disuse-related bone loss result in decreases in bone mineral density, cortical thickness, and trabecular thickness and connectivity. Disuse induces physiological changes in bone similar to those seen with aging. This study compared age- and disuse-related bone loss using C57BL/6J mice of various ages that were hind-limb unloaded (HLU). In male and female mice, HLU induced a bone phenotype between those of 6-month-old and 22-month-old control mice. Gene analysis suggested that HLU leads to mitochondrial dysfunction, while aging primarily downregulates cell cycle processes. Although, the specific response to HLU appeared to be dependent on age. The study identified …

Cellular Metabolism Is A Viable Therapeutic Target For Radiation-Induced Pulmonary Fibrosis, Josly Pierre-Louis Odoom

Theses and Dissertations

Herein, we provide evidence for cellular metabolic reprogramming as a driver of radiation-induced pulmonary fibrosis (RIPF). We are the first to identify a distinct metabolic signature for RIPF in a cohort of patients with radiographic sequela. We also used a RIPF mouse model to detect the metabolic pathways that enrich during pathogenesis. Our previous work highlighted the importance of lactate, a derivative of the glycolysis end-product pyruvate. Consequently, we took a special interest in the effects of radiation on the glycolysis pathway. We learned that radiation accelerates and reprograms glycolysis to an anabolic state in a pyruvate kinase M2 (PKM2)-dependent …

We Built This Country For Free – Using A Phenomenological Approach For (Re) Imagining Mississippi Black Small-Scale Farmers, Destiny Denise Crockett

Theses and Dissertations

By the early 20th century, in 1920, Black farmers owned 14% of US farmland. Today, in the 21st century, Black farmers own less than 2% of US farmland. The demise of Black farmers and Black farmland in US Agriculture is a direct result of social, political, and racial weaponization against their foodways, culture, and livelihoods. The history concerning the plight of Black farmers goes beyond USDA's historical discrimination but enters a position where racism is embedded and perpetuated within the structure of US agriculture. In effect, Black small-scale farmers have reaped the downfall of this system, enduring racial biases and …

Waterbody Size Influences Chemical And Community Characteristics Of North Dakota Prairie Wetlands And Lakes, Julia Renee Hampton

Theses and Dissertations

The Prairie Pothole Region (PPR) of North America is home to dynamic glacier-formed lakes and wetlands that range in size from small intermittent wetlands to large permanently filled basins. Predicting water-related shifts in environmental conditions and biological community responses within these systems has been challenging due to non-linear, scale-specific changes. Furthermore, landscape-level changes in the quantity and distribution of surface water are becoming more frequent. This thesis contributes to our understanding of how waterbody size, and potential size fluctuations, influence chemical and community dynamics of complex PPR glacial lakes and wetlands. We paired remote sensing and discontinuity methods with US …

Climate Change And The Shifting Geography Of Coral-Reef Development, Victor Rodriguez-Ruano

Theses and Dissertations

Coral-reef development is modulated by growth processes that deposit calcium carbonate onto the reef, such as calcification, and destructive processes that remove calcium carbonate from the reef, such as bioerosion. Wherever calcification rates exceed bioerosion rates, there is a net accretion of the reef through time, but where bioerosion rates exceed calcification rates, there is a net destruction of the reef through time. A reef’s framework is the legacy of the interaction of these processes throughout a reef’s history. Studying the fossil frameworks of reefs can shed light on the environmental factors that have controlled reef development in the past, …

A Definition Of Reliable Water Supply For Public Water Systems, Easton Hopkins

Theses and Dissertations

"Reliable water supply" does not have a universal definition in Utah, or the Western United States, where water resources are limited and such a definition would be especially useful. Utah's three water agencies and 500 public water systems have no consistent method to define, evaluate, and report it, potentially leading to an inability to meet regulatory water demands. We propose a unified definition of reliable water supply for Utah's public water suppliers that can also be used elsewhere. The qualitative definition we propose is necessary to precede quantitative evaluations, set policy, and provide consistency to water resources management in Utah. …

Adapting Deep Learning Techniques For Geologic Investigations Of Hydrothermal Venting At Seafloor Spreading Ridges Using Auv Surveys, Isaac Keohane

Theses and Dissertations

Locating hydrothermal chimney sites unlocks research into their correlations with geology, lithospheric cooling, and deep-sea biogeography at seafloor spreading ridges. High-resolution bathymetry and sidescan sonar collected by Automated Underwater Vehicles allows for chimneys, only a few meters wide and tall, and fissures, only a few meters wide, to be resolved across large areas (>100 km2). We developed a Chimney Identification Tool (CIT) that utilizes a Convolutional Neural Network (CNN), a Machine-Learning model able to classify based on shapes and textures, to identify chimneys in 1m-gridded bathymetry. We then utilized the CIT to identify many potential off-axis chimney structures at …

Structure V-1: A Mississippian Mica Workshop In Kershaw County, South Carolina, John Mclellan Dodge

Theses and Dissertations

This thesis reanalyzes the pottery assemblage of Structure V-1 at the Mulberry site (38KE12). Because Structure V-1 was originally hypothesized to be evidence of a late seventeenth century occupation at the Mulberry site, the framework I use for this research focuses on identifying evidence of community coalescence after Mulberry’s initial occupation ended. However, new evidence from both the pottery and radiocarbon analysis conclusively dates the structure to around the sixteenth century Mulberry I phase. With that new date in mind, I explore the role mica craft production within Structure V-1 might have had in linking the community at Mulberry to …

Channel Morphology Of A Leaky Coastal Plain River: The Congaree River, Sc 1884-2022, William Nicholas Logan

Theses and Dissertations

Downstream changes in river planform can be associated with changes in geologic controls and often signal changes in channel geometry, bed slope, or bed material grain size. While previous studies documented downstream trends in channel geometry and planform for a variety of rivers, there is a gap in the literature on spatial and temporal trends in channel geometry on the fluvial part of Coastal Plain rivers, i.e., the not-tidally influenced part. The literature highlights the existence of crevasse splays in natural levees that allow floodplain inundation below bankfull conditions as unique feature of channels and floodplains in the Coastal Plain. …

A Comparative Measure Of Judicial Legitimacy, Rahul Hemrajani

Theses and Dissertations

In the Federalist papers, Hamilton emphasized the vulnerability of courts as the weakest branch of government, lacking both the power of the "purse" and the "sword." Consequently, courts can secure compliance with their decisions only if people believe in the legitimacy of their actions. Courts that are seen as legitimate by the public can better prevent governmental overreach, enhance the rule of law, and protect democratic rights. However, there is no consensus on how to validly measure the legitimacy of courts. Additionally, existing research on legitimacy focuses on courts in the United States; we know little about judicial legitimacy in …
