Oxidation Energies of Chromium and Tungsten Substituted Ni (111) Surfaces

Creator:: Roth, Anika
Abstract:: The corrosion and heat resistance properties of nickel alloys are hallmarks of their importance in infrastructure and industrial catalysis processes, but these properties are highly dependent on the chemical composition of the alloy surface. Density functional theory was used for analysis of surface oxidation of four combinations of chromium and...

Public Policy Barriers to Carbon Capture and Storage in California

Creator:: Andrews, Kathleen M.
Abstract:: Many industries in California are difficult to decarbonize, making carbon capture and storage (CCS) essential to reach net zero. California has committed to deliver an enormous 100 thousand tons per year of carbon storage by 2045. Despite much interest in carbon sequestration, there are currently no active geologic carbon capture...

Hearing Inequality: A Sonification of the Gender Disparity in Computer Science and Engineering

Creator:: Cohen, Elyse
Abstract:: Sonification, or the “technique of rendering sound in response to data and interactions” [1], is an alternative to visual graphs and has the potential to make data more interpretable and accessible. As a combination of the arts (music) and the sciences (data), sonification is an interdisciplinary tool for connecting people...

Urban Forests Role in Ecosystem Services in the 24:1 Community and the Normandy Schools Collaborative of St. Louis County, Missouri: A Study in Environmental Justice

Creator:: Templer, Amanda L.
Abstract:: The 24:1 Community is a growing community with ongoing concerns over historical residential segregation, minority-exposure to environmental hazards, and sparse tree canopy coverage. This paper presents a comprehensive review of the current state of the community’s urban forest through an assessment of the urban forest. It also highlights the need...

Removing Residual Lane Markings to Reduce Driver Confusion

Creator:: Weber, Jane B.
Abstract:: When pavement markings on roadways are removed, scarring can occur leaving behind traces of where the marking used to be called ghost lines. These ghost lines can confuse drivers on the roadway and divert their attention from the correct lane markings leading them into the false lane. Previous research has...

Bees of the Pacific Northwest : key to Lasioglossum species for females of the subgenera Hemihalictus, Sphecodogastra, and Evylaeus in Oregon (Hymenoptera : Halictidae)

Creator:: Engler, Joseph D., Gorman, Mark, Cappaert, David, Stanton, Marek, Best, Lincoln R., and Jackson, August S.
Abstract:: The following taxonomic keys are adapted in part from the subgeneric and species descriptions and keys produced by McGinley (2003), Gibbs et al. (2013) and Gardner and Gibbs (2022). Additional identification information was provided by Jason Gibbs, Thilina Hettiarachchi (University of Manitoba), and Joel Gardner (Washington State University). While these...

Greening a Red State: Understanding the Complexities of Environmental Policy in Florida

Creator:: Dearden, Grace
Abstract:: In some legislative bodies, the use of terms like climate change and global warming is frequently seen as taboo. In the United States, voters who identify as right-leaning have reported little concern about the environment or climate change. This lack of interest is mirrored by Republican legislators who often publicly...

Public Engagement with Science at Luquillo-Long-Term Ecological Research Program: Results from a Case Study

Creator:: Archibeque, Ben, O'Connell, Kari, Delgado, Isabel, Nytch, Christopher, Merlo, Nancy, and Ortiz Franco, Emily
Abstract:: The goals of this work are to a) understand community perspectives related to public engagement with science and the Luquillo Long Term Ecological Research (LUQ-LTER) program, b) enhance existing relationships within these communities, and c) illuminate opportunities for establishing new relationships between the LUQ-LTER program and its surrounding community. We...

Spatiotemporal Variability in Benthic-Pelagic Coupling on the Oregon-Washington Shelf: An Investigation of Bottom Water and Benthic Flux Data

Creator:: Hughes, Anna R.
Abstract:: Continental shelf sediments are sinks for dissolved oxygen and sources of many major and minor nutrients required for oceanic surface primary production, resulting in a strong coupling between benthic and pelagic biogeochemical cycling. However, the influence and spatiotemporal variability of benthic remineralization on bottom-water chemistry and the supply of nutrients...

Intensification of Solvent Extraction in an Additively Manufactured Microfluidic Separator

Creator:: Touma, Jad George, Coblyn, Matthew, Freiberg, Lucas Joseph, Kowall, Cliff, Zoebelein, Avaline, and Jovanovic, Goran Nadezda
Abstract:: Solvent extraction is an integral chemical and biochemical separation process that is drastically intensified in microfluidic systems. A novel high-throughput micro-separator was additively manufactured for the intensification of liquid–liquid separation. The micro-posts array within the flow plate generated a capillary pressure gradient on the non-wetting organic phase, enabling continuous, membrane-free,...

Drought response in herbaceous plants: A test of the integrated framework of plant form and function

Creator:: Funk, Jennifer L., Larson, Julie E., Blair, Megan D., Nguyen, Monica A., and Rivera, Ben J.
Abstract:: 1. Multidimensional trait frameworks are increasingly used to understand plant strategies for growth and survival. However, it is unclear if frameworks developed at a global level can be applied in local communities and how well these frameworks—based largely on plant morphological traits—align with plant physiology and response to stress. 2....

Supporting merge comprehension when resolving merge conflicts

Creator:: Nelson, Nicholas
Abstract:: Distributed version control allows developers to manage software evolution among distributed development teams. But it does not eliminate all consistency and concurrency issues, and instead introduces additional complexity when merging code. And resolving merge conflicts is nontrivial when automated merging fails. In such cases, developers are forced to inspect the...
