  • The influence of an elevated incubation temperature on the expression of clubbed down in Coturnix embryos

    Creator:
    Charbonneau, Jack R.
    Abstract:
    Hatchability of the fertilized avian egg is impacted by factors which can be categorized as being either genetic or environmental in nature. An elevated incubation temperature, > 100 F reduces development time (time, days to hatch), but increases embryonic mortality and lowers the numbers of fertile eggs that will hatch....

  • Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

    Creator:
    Lee, James E.
    Abstract:
    Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...

  • Evaluating Stiffness Metrics for Predicting the Cost of Chemical Kinetics Integration

    Creator:
    Alferman, Andrew Thomas
    Abstract:
    Simulations of combustion and reacting flows often encounter stiffness in the equations governing chemical kinetics. Explicit solvers for these ordinary differential equations offer low computational expense, but typically cannot efficiently handle stiff systems. In contrast, implicit methods demand greater expense but offer unconditional stability—as a result, most reactive-flow solvers rely...

  • Generalized Preconditioning to Accelerate Simulations with Large Multiphase Chemical Kinetics Models

    Creator:
    Walker, Anthony S.
    Abstract:
    Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...

  • Understanding Signals of the South Pole Ice Core: Chronology, Climate, and Firn Processes

    Creator:
    Epifanio, Jenna A.
    Abstract:
    The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...

  • An Exploratory Study on Family Group Use of a Multi-touch Table Exhibit at a Public Marine Science Center

    Creator:
    East, Jennifer L.
    Abstract:
    Museums, aquariums, and technology centers are informal learning environments that facilitate the understanding of scientific phenomena while supporting self-motivated learning. Families are a social group that frequently visits these sites. There are multiple opportunities for adults and children to engage in independent sense-making and collective discussion about their experiences with...

  • Communicating science : developing an exhibit with scientists and educators

    Creator:
    Lemagie, Emily
    Abstract:
    Outreach is a small, but significant component to modern research. Developing an exhibit for public display can be an effective way to communicate science to broad audiences, although it may be a less familiar method to scientists than writing papers or giving presentations. I outline the process of developing an...

  • The impacts of ionization chemistry on hydrocarbon detonation

    Creator:
    Zaiger, Matthew F.
    Abstract:
    As carbon emissions are negatively impacting ecosystems across the globe, researchers are in a race against time to provide cleaner and more eÿcient power. Detonation engines can help meet the increasing demands for cleaner and more eÿcient power generation by providing an alternative means to use oxy-fuel combustion for carbon...

  • Kinetic analysis of avian sarcoma virus integrase in the presteady-state

    Creator:
    Bao, Kogan K.
    Abstract:
    Integrase catalyzes insertion of a retroviral genome into the host chromosome. Following reverse transcription, integrase binds specifically to the ends of the duplex retroviral DNA, endonucleolytically cleaves two nucleotides from each 3'-end (the processing activity), and inserts these ends into the host DNA (the joining activity) in a concerted manner....

  • Dynamics of the Laurentide Ice Sheet

    Creator:
    Carlson, Anders Eskil
    Abstract:
    This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...
