New Foraminifera-Based Proxies to Trace Changes to the Organic and Inorganic Carbon System Since the Last Glacial Maximum

Creator:: Fritz-Endres, Theresa
Abstract:: 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...

There’s a Long, Long Trail to Tipperary: Soldier Song Investigation and Development During the First World War

Creator:: Delgado, Nolan Schreiner
Abstract:: From 1914-1918 the world experienced humanity’s ultimate affirmation of malice on scales scant seen in the centuries before. The Great War wrought terror on an industrial scale, throwing men headlong unto landscapes rent low by fire and steel. Our collective unconscious image of the war does well to demonstrate this....

Two Sides of a Coin: Adversarial-Based Image Privacy and Defending Against Adversarial Perturbations for Robust CNNs

Creator:: Rajabi, Arezoo
Abstract:: Emergence of highly accurate Convolutional Neural Networks (CNNs) with the capability to process large datasets, has led to their popularity in many applications, including safety/security-sensitive (e.g. disease recognition, self-driving cars). Despite the high accuracy of convolutional neural networks, they have been found to be susceptible to adversarial noise added to...

New Graphite Intercalation Chemistry with Alkaline Earth Metals

Creator:: Xu, Wei
Abstract:: Novel graphite intercalation compounds (GICs) and associated chemistry have been explored, specifically: (1) containing alkyl- substituted imidazolium cations; (2) a series containing alkaline earth metal (Mg, Ca, Sr, Ba) cations with ethylenediamine (en) co-intercalates; (3) showing reversible intragallery M-M bonding and (4) via electrochemical intercalation of Mg cations with potential...

Purification of cyclotron-produced 89Zr for its use in diagnostic radiopharmaceutical labeling

Creator:: Knaus, Clinton W.
Abstract:: Production of 89Zr serves as a crucial preliminary step for exploring Zr-chelates, determining their stability constants, and advancing radiolabeling methodologies for monoclonal antibody based theranostics. 89Zr is typically produced by the irradiation of natural yttrium targets, a process extensively documented in scientific literature. Two primary methods are employed: the 89Y(p,n)89Zr...

A New Record of Planktic Foraminifera Community Response to Marine Heatwaves in the Northeast Pacific

Creator:: M. Kelsey Lane
Abstract:: Marine heat waves are forecasted to increase in frequency and intensity under future climate scenarios, but little is known about the impact of these events on the one of the most commonly used proxies of ocean temperature - foraminiferal assemblages. This research explores the planktic foraminifera community along the Newport...

Regulation of Redox Homeostasis in Skin Cells for the Prevention of UV-Induced Stress and Treatment of Melanoma

Creator:: Carpenter, Evan L.
Abstract:: Melanocytes are dendritic, pigment-producing cells located in the skin and are responsible for its protection against the deleterious effects of solar ultraviolet radiation (UVR), which include DNA damage and elevated reactive oxygen species (ROS). They do so by synthesizing photoprotective melanin pigments and distributing them to adjacent skin cells (e.g.,...

Process Intensification toward Reduced Exergy Destruction in Methane Upgrading

Creator:: Freiberg, Lucas J.
Abstract:: Exergy relates to thermodynamic value or usefulness in the universe. In this dissertation, three methods in the realm of "process intensification" are explored to reduce exergy destruction by equipment and processes that are used to convert and upgrade methane. Thermodynamic efficiency of a virtual heat exchanger is improved with a...

Using Point Clouds for Single Tree Forest Inventory at the Beginning and End of the Rotation

Creator:: Garms, Cory G.
Abstract:: The portability and reduced price of unmanned aerial systems (UAS) in recent years has led to a broad range of new UAS-enabled scientific inquiries, including for forestry. Small, consumer-grade UAS are advantageous for forest measurements due to their portability, ease and safety of deployment, and notably, they are currently the...

Innate behavioral responses to extirpated mammalian apex predators : can fear be utilized to manage populations and protect sensitive habitats

Creator:: Ruch, Zachary
Abstract:: I conducted a field study using gray wolf and mountain lion urine to investigate white-tailed deer and mesopredator behavioral responses to novel predator cues in a natural setting and to see if any changes in wildlife activity correspond to changes in the local biodiversity of a wetland environment. I created...
