Seismic refraction, reflection and gravity data obtained
across the Peru continental margin and Nazca Plate
at 9° S. permit a detailed determination of crustal structure.
Complex structures normal to the profile require the
development of a ray trace technique to analyze first and
later arrivals for eleven overlapping refraction lines....
From my personal experiences, I’ve noticed that Latinx students and families are most receptive to college-related information communicated as anecdotes. Latinx students are among the most poorly represented demographic at universities nationwide, which I believe can be mitigated through calculated efforts to increase collegiate literacy and understanding. This project is...
Wheat (Triticum aestivum) is a highly valuable crop that makes up a large portion of the world’s food. However, breeding for improved varieties with desirable characteristics can be a challenge. This research examined two different issues wheat breeders deal with throughout the selection process all the way to production of...
Marine sediments are one of the largest habitats for microbial life on earth. These microorganisms play critical roles in biogeochemical cycling both within the subsurface and between the sediment and water columns. However, microbial communities in sediments are highly heterogeneous and the factors defining microbial community structure and metabolic function...
The enactment of the Patient Protection Affordable Care Act (ACA) in 2010 marked a critical moment in American healthcare history. The ACA introduced Medicaid expansion, a policy designed to extend healthcare coverage to a larger population of low-income Americans. This policy quickly became a topic of debate and led to...
The Cascadia subduction zone has been characterized as a typical Chilean-type
subduction zone based on qualitative comparisons of plate age and convergence rate, with
simple forearc structure. However, the discovery of unusual structural styles of
deformation, variations in the morphology of the forearc, and its absence of seismic activity
suggest...
In this thesis we define two nxn matrices T and S to be isoconjunctive if there exists an nxn nonsingular hermitian matrix H such that T = HSH. We then proceed to establish necessary and sufficient conditions that two nxn matrices T and S be isoconjunctive in the case where...
The production of carbon and export to deep ocean sediments is linked to carbon partitioning between the ocean and atmosphere and is a key driver of climate change over the glacial-interglacial transition. Yet conflicting reconstructions create barriers to understanding changes to the carbon system over this important climate transition. Production...
