College Football Or Abortion Education? An Examination Of The University Of Arizona’S 1974 Stadium Bonds Bill, Emma Masterson

History ETDs

In 1974 the University of Arizona renovated their football stadium through a bonds bill passed by the state legislature. The renovations allowed the university to increase the stadium’s capacity by 17,000 seats. While in the state house, an Arizona Congressman attached a rider to the bonds bill banning the university’s medical school from performing abortions in most circumstances, effectively barring the university from teaching the medical students how to perform the procedure as well. This thesis seeks to position the University of Arizona football stadium renovations and abortion ban within the larger histories of American higher education and Arizona. This …

Optimizing Distributed Boundary Exchanges For Benchmarks, Solvers And Sparse Matrix Operations, Gerald Collom

Computer Science ETDs

Boundary exchanges dominate the cost of both stenciled codes and those that rely on sparse matrix operations. The performance of large boundary exchanges is limited by synchronization overheads and injection bandwidth limitations. Irregular boundary exchanges incur additional overheads due to the large number of required messages. This thesis investigates multiple methods for improving the performance and scalability of both Cartesian and irregular boundary exchanges. Since boundary exchanges are typically performed iteratively, persistent communication presents an opportunity for optimization by sharing and amortizing setup costs. Partitioned communication is also explored to increase asynchrony, reducing bottlenecks from synchronization overheads and data congestion. …

Secured Through Stone: The Power, Monuments, And Memory Of Thyra Danmarkarbót And The Jelling Dynasty, Jacquelyn Truitt

History ETDs

Sometime in the mid-tenth century on the Jutland peninsula of Denmark, the Viking Age Queen Thyra (d. ca. 958/9) passed away and the epithet Danmarkarbót—Denmark’s Adornment—was skillfully carved onto her memorial runestone. Yet Thyra’s story has been clouded by few and unreliable textual sources, by differing assessments of her familial background that have emerged from those sources, and by misrepresentations of the material culture relating to her. This thesis explores Thyra and her place within the Viking Age Jelling dynasty through textual and material evidence and considers how the construction of both medieval and modern memory work and memorialization …

This data will be used as guidance for the linear and constant model. The performance of this model was compared with the curve number model for a hypothetical 100-year design storm. Results showed that gravel mulch increased infiltration rates by 66% and reduced erosion on steep and …

The Nature Of Anthropogenically Driven River Drying: Spatiotemporal Causes And Consequences, Eliza Inez Gilbert

Biology ETDs

Streambed drying naturally occurs in over 60% of rivers and streams worldwide. Climate change and human regulation of surface and groundwater have increased drying in naturally intermittent systems and caused perennial systems to transition to intermittency, impacting water security, water quality, and biodiversity. To understand human-induced drying dynamics, we used 12 years of daily drying data along a 154-km regulated reach of the Rio Grande. We conceptualized river drying as a regime analogous to the natural flow regime paradigm and quantified drying magnitude, rate of change, and duration. Although linear models predicting drying magnitude and rate of change were uninterpretable, …

Nitrogen Addition Additively Boosts Climate-Driven Salsola Tragus (Russian Thistle) Invasion Into Southwestern Usa Grasslands, Melissa A. Bacigalupa

Upcycling Of Polydicyclopentadiene (Pdcpd) Via Dynamic Bonds, Catherine Biju

Biomedical Engineering ETDs

Thermoset polymers are valued for their exceptional mechanical strength and thermal stability, but suffer from irreversibility due to permanent covalent crosslinks, limiting recyclability. Polydicyclopentadiene (pDCPD), a widely used thermoset, exemplifies this limitation despite its excellent mechanical properties. In this study, we report an upcycling strategy for pDCPD through the incorporation of dynamic imine bonds. The successful integration of imine bonds was confirmed by ¹H NMR spectroscopy. Mechanical testing revealed that the modified pDCPD (pDCPD-imine) exhibits enhanced tensile strength and maintains its performance across multiple reprocessing cycles. Moreover, the dynamic nature of the imine bonds imparts healability to the network. This …
