  • Optimal soaring by a small autonomous glider

    Creator:
    Kyle, Jason A.
    Abstract:
    Extending the flight time of an autonomous unmanned air vehicle by soaring is considered. A suboptimal controller is developed and successful static soaring is demonstrated with a 6 degree of freedom glider model. Altitude gain rates of between ¼ and ½ m/s are achieved with this simple implementation. A hybrid...

  • Predicting the effects of climate change : effects of thermal stress on seaweeds in the Galapagos rocky intertidal

    Creator:
    Harris, Alyssa L.
    Abstract:
    Because global warming is predicted to increase the severity of El Niño events in the future, understanding how warmer temperatures affect seaweed growth and the animals associated with seaweeds is important for predicting how marine ecosystems will change. The Galapagos Islands of Ecuador are considered a living laboratory for studying...

  • Effects of teaching games for understanding on game performance and understanding in middle school physical education

    Creator:
    Harvey, Stephen
    Abstract:
    Most students arrive at game-focused physical education (PE) with neither the skills nor the tactical knowledge to be successful (Metzler, 2000). Although the Teaching Games for Understanding (TGFU) approach can enhance both on- and off-the-ball skills in game play performance (Griffin et al., 1995; Harvey et al., in review, Harvey...

  • A phenomenological inquiry into the experience of reflection by older adults in adventure-based experiential education

    Creator:
    Brennan, L. A.
    Abstract:
    This phenomenological inquiry explored dimensions of reflection for older adults in a developmental oriented adventure education experience. Data were gathered from emergent interviews with four individuals while participating in a multi-day, self-contained experiential education program conducted in a rugged environment, and led by a Navajo leader. Two principle research questions...

  • Publicly Funded, Privately Assisted : The Role of Giving in Oregon K-12 Education

    Creator:
    Sattem, Jennifer L.
    Abstract:
    In Oregon, property tax revolts and school equalization measures have led to increasingly unstable and more non-discretionary public funding for schools. As a result, public schools are turning to private donations to provide both basic and supplemental educational opportunities. Some schools and districts are raising hundreds of thousands of dollars,...

  • Transcriptional repression by CTIP2, a C2H2 zinc finger protein

    Creator:
    Topark-Ngarm, Acharawan Khamsiritrakul
    Abstract:
    CTIP2, a novel C2H2 zinc finger protein, is a transcriptional repressor that functions by at least two mechanisms. CTIP2 interacts with and stimulates transcriptional repression mediated by COUP-TF family members. CTIP2 also represses transcription independently of COUP-TF proteins by direct, sequence-specific DNA binding activity. CTIP2 has been implicated in lymphoid...

  • Formation and modification of enduracididine, a nonproteinogenic amino acid

    Creator:
    Tan, Ying
    Abstract:
    Molecular genetic and enzymological techniques have been employed to study antibiotic biosynthesis. In this thesis, we studied the formation and modification of the nonproteinogenic amino acid enduracididine (End), which exists in two important antibiotics, mannopeptimycins (MPPs) and enduracidin. Sequence analysis of the MPP gene cluster revealed that the product of...

  • Spatial and temporal variability of carbon dynamics in a tropical forest of Colombia

    Creator:
    Sierra, Carlos Alberto
    Abstract:
    Despite the importance of tropical forest ecosystems in the global carbon cycle, there have been few studies of carbon dynamics in this biome. The magnitude of carbon stocks in the tropics and their changes over time are poorly known since ground-based observations are lacking. In this study, total carbon stocks...

  • Activation, incorporation and modification of capreomycidine during viomycin biosynthesis

    Creator:
    Fei, Xiaobo
    Abstract:
    Molecular genetic and enzymological techniques have been employed to study antibiotic biosynthesis. The nonproteinogenic amino acid capreomycidine is the signature residue found in the tuberactinomycin family of antitubercular peptide antibiotics and an important element of the pharmacophore. Recombinant VioG, a single module peptide synthetase from the viomycin gene cluster cloned...

  • The Oregon Coast Aquarium : A case study

    Creator:
    Van Zwalenburg, Kim P.
    Abstract:
    The following paper traces important decision processes connected with initiating and constructing a coastal environmental facility. There is a brief review of the early history and summaries of the preliminary studies completed as of April 1986. Particular focus is placed on the Oregon State University/Oregon Coast Aquarium cooperative study. Finally,...
