  • Hydrogel Immobilizations for Anammox Enrichment

    Creator:
    Stein, Grant
    Abstract:
    Long delays in reactor startup due to high biomass washout have hindered the development of efficient and cost-effective wastewater treatments based on the anammox process. This can be remedied with efficient biomass retention systems. In the following study, anammox bacteria were successfully enriched in hydrogel immobilizations of polyvinyl alcohol (PVA)...

  • Anammox Enrichment and Kinetics

    Creator:
    Kannan, Rahasudha
    Abstract:
    Anammox (Anaerobic Ammonium Oxidation) is a significant biogeochemical process carried out by certain bacteria, generally referred to as anammox bacteria. These bacteria have the ability to anaerobically oxidize ammonium (NH4+) with nitrite (NO2-) to form nitrogen gas (N2) without an organic carbon source. While anammox bacteria are found in a...

  • Analysis and Modeling of Kinetic Parameters for Urea Hydrolysis by Bacteria for Use in Calcium Carbonate Precipitation in Aquifers

    Creator:
    Neighbor, Christopher J.
    Abstract:
    The use of ureolytic bacteria for the remediation of contaminated groundwater aquifers by inducing calcium carbonate precipitation is being studied in order to establish a better understanding of the modeling and prediction of how the bacteria will act in situ. This research has pursued the use of various ureolytic bacteria...

  • The Dynamics of Random Pulse-Coupled Oscillator Networks

    Creator:
    Kadhim, Kyra L.
    Abstract:
    The pulse-coupled oscillator model is widely used to simulate the dynamics of neural systems. For networks with particular internal (Mirollo-Strogatz) dynamics, I will define three broad patterns of collective behaviors found in literature in terms of inter-spike interval (ISI) statistics. These patterns are i) temporally-regular, characterized by all oscillators in...

  • Developmental effects of micro- and nanoscale tire particles and recycled rubber on zebrafish

    Creator:
    Mottern, Taylor H.
    Abstract:
    Plastics have become an essential part of everyone lives, found in almost every product made today. Tires only make up a fraction of these products but as their use increasing so does the microplastics that flake off. Many studies have evaluated the toxic effects of tire particles on aquatic environments...

  • Investigating the Hemocompatibility of Blood-Contacting Biomaterials

    Creator:
    Hummel, Madeleine H.
    Abstract:
    Surface-associated thrombosis is a critical concern in medical device development. Current extracorporeal circulation units require systemic anticoagulation to avoid thrombosis, which can cause adverse effects such as thrombocytopenia, hypertriglyceridemia, and hyperkalemia. To address this issue, we combine the technology of polydopamine (PDA) functionalization with slippery liquid infused porous surfaces (SLIPS)....

  • Activation and Nuclear Translocation of the Transcription Factor Nrf2 by the MAP Kinase Family

    Creator:
    Nguyen, Ngan H.
    Abstract:
    Eukaryotic cells have developed elaborate biochemical processes to counteract oxidative stress, electrophiles, or carcinogens due to environmental insults. One of these important cellular defense mechanisms is mediated by the transcription factor Nrf2 that have been shown to have decrease activity with age. While the process of which Nrf2 is involved...

  • Biomechanical Modeling of Isometric Muscle-Tendon Force Generation Through Tendons Coupled in Parallel and a Passive Differential Mechanism

    Creator:
    Le, Anthony H.
    Abstract:
    There are at least fifteen types of upper extremity tendon transfer procedures for combined peripheral nerve injuries that involve re-routing a single donor muscle to multiple recipient tendons. As a result, force and movement across finger joints become coupled, resulting in limited grasping abilities. Quantification and modeling of the donor...

  • Disability to Super-Ability: Issues Along The Human Enhancement Spectrum

    Creator:
    Oakes, Ian R.
    Abstract:
    Advancements in the field of medical and computer technology promise a new age of human enhancement technology (HET). These technologies may be aptly applied to existing Assistive Technology (AT), which was created to ameliorate disability, moving one up the spectrum of ability. This study aimed to determine how these technologies...
