  • Temperature stress, gene expression, and innate immunity at the onset of cnidarian-dinoflagellate symbiosis

    Creator:
    Schnitzler, Christine E.
    Abstract:
    The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...

  • Techno-economic and Life-cycle Analyses of Glucosamine and Lipid Production from Marine Diatom Cyclotella sp.

    Creator:
    Xiang, Xuwen
    Abstract:
    Currently the production of biofuel from algae is not economically competitive with petroleum fuel. However, co-production of high-value products may be able to justify the cost of large-scale algae cultivation. The basic goal of this study is to develop a techno-economic analysis (TEA) and Life-cycle assessment (LCA) for the production...

  • Functional polymers and proteins at interfaces

    Creator:
    Schilke, Karl F.
    Abstract:
    Functional polymers and proteins at interfaces and surfaces are of fundamental importance for biomaterials, biocatalysis and microreactor applications. Candida antarctica lipase B immobilized on poly-DL-tryptophan tethers showed 30x higher specific activity in aqueous and non-aqueous media than the same enzyme adsorbed or covalently bound directly to the surface. An excess...

  • The growing skeleton : influence of lifestlye and the development of normative data using DXA

    Creator:
    Fuchs, Robyn K.
    Abstract:
    To examine the potential for exercise to build bone mass during growth, objectives of this dissertation included: 1) determine the effects of 7 months of jumping followed by 7 months of detraining on hip and spine bone mass in the prepubertal children; 2) determine variables that best predict bone mineral...

  • Weighted vest exercise improves functional ability in women over 75 years of age

    Creator:
    Protiva, Karen W.
    Abstract:
    The purpose of this study was to determine the effects of long-term weighted vest exercise on hip bone mass, functional ability and static balance in elderly women. This was a within subject exercise intervention study and included a 6-month control period. Twenty-three subjects (age 85 ± 6) were recruited and...

  • New application of crystalline cellulose in rubber composites

    Creator:
    Bai, Wen
    Abstract:
    Rubber without reinforcement has limited applications. The strength of reinforced rubber composites can be ten times stronger than that of unreinforced rubbers. Therefore, rubber composites are widely used in various applications ranging from automobile tires to seals, valves, and gaskets because of their excellent mechanical elastic properties. Silica and carbon...

  • Spatial and temporal dynamics of sediment and wood in headwater streams in the central Oregon Coast Range

    Creator:
    May, Christine L.
    Abstract:
    Channels that were scoured to bedrock by debris flows provided unique opportunities to calculate the rate of sediment and wood accumulation, to make inferences about processes associated with input and transport of sediment, and to gain insight into the temporal succession of channel morphology following disturbance. In an intensive investigation...

  • Vitamin B-6 and pyrimidine deoxynucleoside metabolism in the rat

    Creator:
    Jensen, Christine May
    Abstract:
    Serine transhydroxymethylase (STHM), a pyridoxal 5'- phosphate requiring enzyme is indirectly involved in pyrimidine deoxynucleotide metabolism. A decrease in the activity of this enzyme could lead to altered deoxycytidine (dC) metabolism. This study was undertaken to determine if a vitamin B-6 deficiency affects dC metabolism. The effect of a vitamin...

  • An Exploration on How Institutional Practices and Support Systems Support or Hinder Community College Basic Skills Students Transitioning to Postsecondary Education: A Case Study

    Creator:
    Knighton, Christine M.
    Abstract:
    Many jobs in the United States have shifted to requiring education beyond high school credentials. Many potential workers are enrolled in pre-postsecondary education, or basic skills. A small percentage of students transition from basic skills to postsecondary education. Research identifies key institutional practices and supports have shown to increase transitions,...

    Stephenson, Christine (Christine Gale)
    Abstract:
    This research addressed the role of educational technology associations as change agents within education with particular emphasis on issues of advocacy and leadership. Using a poststructural feminist lens and the metaphor of interview and analysis as storytelling, it explored the perspectives of nineteen individuals belonging to a national level educational...
