  • 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...

  • Indirect effects of fishing on predators and their prey

    Creator:
    Stallings, Christopher Derek
    Abstract:
    Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...

  • Selected risk factors contribute to homelessness among youth : a comparative study of Chile and the United States

    Creator:
    Minks, Kelly and Minks, Kelly K.
    Abstract:
    Youth who are at-risk of homelessness are placed into jeopardizing situations because they are often pushed toward the outer edges of society, disconnected from healthy support networks, involved in illegal activities, and their chances of having successful futures are, in turn, diminished. The goals of this project were to: review...

  • Social change and children’s well-being in Chile

    Creator:
    Iwanaga, Kanako
    Abstract:
    Chilean society has been changing rapidly for the last few decades during a time of rapid economic growth. Some sociological and economical analyses state that when a nation grows, inequality between the rich and poor grows too, leaving the poor behind. The Chilean economy is the most rapidly growing in...

  • 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...

  • Human gait analysis by gait pattern measurement and forward dynamic model combined with non linear feedback control

    Creator:
    Ko, Seung-uk
    Abstract:
    Normal gait of human is believed to be an adapted motor control result of optimal behavior of individual. Normal gait would be altered by aging or injury without being perceived. Subtle changes in gait which is not easy to detect, can cause many serious problems including joint pains and even...

  • Barriers to Community Involvement across Rural and Urban Communities

    Creator:
    Torgerson, Melissa
    Abstract:
    Many communities emphasize participatory involvement in local development or reinvention efforts. Recognizing barriers among specific groups could help community leaders identify what may be constraining underrepresented groups from joining in. Utilizing data from the Social Capital Benchmark Survey, this research examined identified “barriers” to community involvement among individuals in rural...

  • Efficacy of electrolyzed oxidizing water and ozonated water for microbialdecontamination of fresh strawberries (Fragaria x ananassa)

    Creator:
    Udompijitkul, Pathima
    Abstract:
    The objectives of this project were to evaluate the efficacies of electrolyzed oxidizing (EO) and ozonated waters as antimicrobial agents for enhancing the microbiological safety of fresh strawberries (Fragaria x ananassa). The influence of sodium chloride (NaCl) concentrations used for preparing EO water was evaluated on their bactericidal activities against...

  • 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...
