  • Arsenic methylation by marine cyanobacteria Prochlorococcus and Synechococcus

    Creator:
    Lee, Mikaela
    Abstract:
    Our experiments aimed to investigate responses of the marine cyanobacteria Prochlorococcus and Synechococcus to toxic arsenic species, such as arsenate, and to understand cellular mechanisms that contribute to arsenic tolerance. We used two strains of Prochlorococcus, a high-light adapted MED4 and low-light adapted MIT9313, both axenic, for cultivation experiments. For...

  • Investigating physical drivers of phytoplankton bloom initiation in the Northern Gulf of Alaska

    Creator:
    Ballantine, Kaleigh
    Abstract:
    The spring bloom is a key oceanic phenomenon in the Northern Gulf of Alaska (NGA), where it supports the regional ecosystem, fisheries, and CO2 sequestration. Despite its significance, mechanisms that trigger NGA blooms are still debated, largely due to a lack of sufficient data from late winter through spring. New...

  • Numerical Analysis of Experimental Impacts on Wind Turbine Blades

    Creator:
    Fleiger-Holmes, Kahlan
    Abstract:
    Wind energy is one of the fastest growing renewable forms of energy in the United States and the world. However, interactions between wind turbines and wildlife have the possibility to injure animals such as birds and bats. Strategies to assess and minimize wind turbine interactions with wildlife are critical for...

  • Developing a Method For Quantitation of Organic Acid Exometabolites Released By Streptococcus mutans Biofilm Grown Under Oral Cavity-like Conditions

    Creator:
    Akmal, Ryaan
    Abstract:
    Tooth decay in the form of dental caries and cavities is estimated to be among the most common health conditions globally, with treatment of these oral diseases resulting in a massive, world-wide economic burden. The cause of this demineralization of teeth is rooted in the action of complex microbial biofilms...

  • Sensorless Localization for Robots and Wheelchairs

    Creator:
    Subramanian, Ashwin
    Abstract:
    Despite an increase in the number of people who rely on manual wheelchairs, there are still substantial economic barriers to affordable and accessible localization systems. As a result, there is a pressing need to build a versatile yet low cost localization system for manual wheelchairs. Such systems allow users to...

  • Validation of Design For Additive Manufacturing Heuristics for Aperiodic Structures through Application to Regular Structures

    Creator:
    Schipper, Paxton
    Abstract:
    Aperiodic structures cause significant challenges to subtractive manufacturing methods due to the common features such as inaccessible voids within the structure. Additive man- ufacturing presents an appealing alternative for this purpose. The aim of this research is to test analysis heuristics for validity through application to periodic structures. First, a...

  • Does Athleticism Moderate Reactions to Diverse Images?

    Creator:
    Gregory, Charlotte
    Abstract:
    There is significant evidence that an increase in social media usage causes changes to mood and feelings about the self. It has also been found that there is a significant relationship between the extent of social media usage consumption and self-perception. Mimicking social media exposure, I focused on how participants...

  • Electrical Conductivity of Ceramic Material at High Temperature

    Creator:
    Kangsathein, Parm
    Abstract:
    The electrical conductivity data of ceramic material at high temperatures can be useful in the application of modeling, solid oxide fuel cell (SOFC), and magnetohydrodynamic (MHD). The existing data is considerably lacking at extreme temperatures. Our research focuses on bridging this gap by reporting the electrical conductivity measurements of sets...

  • 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...

    Abstract:
    The “why” of any situation is one of the most important questions to ask. Inventors have ideas every day. Some ideas are the brilliant ideas that lead to a better tomorrow. To protect these ideas, inventors turn to patents, a governmental grant of the right to stop others, for a...
