  • Properties and conformation of P-form DNA

    Creator:
    Zehfus, Micheal H.
    Abstract:
    Work is presented which explores the properties and nature of the P-form of DNA. Initially the P-form represented an unknown state of DNA which occurred when this molecule was in a solvent of 47.5% methanol, 5% water, and 47.5% ethanol, and which showed properties of both native and denatured conformations....

  • On sequential/parallel matrix array languages

    Creator:
    Wang, Patrick Shen-Pei
    Abstract:
    A new system called sequential/parallel matrix grammars for two-dimensional pattern processing is introduced and studied. Miscellaneous language operations such as union, catenation (row and column), Kleene's closure (row and column) and substitutions are investigated. The equivalence of sequential/parallel matrix languages and finite-turn repetitive checking automata is established. Hierarchies for both...

  • Point and nonpoint source mercury pollution of Oregon Reservoirs

    Creator:
    Park, Jeong-Gue
    Abstract:
    Two Oregon reservoirs contaminated by different mercury sources were compared for mercury distribution in sediment and bioaccumulation by fish. The average mercury concentration in the sediment of Cottage Grove reservoir (0.67 ± 0.05 μg/g dry wt) was higher than for Dorena Reservoir (0.12 ± 0.01 μg/g dry wt). Sediment mercury...

  • Temperature-modulated 7,12-dimethylbenz(a)antheracene carcinogenicity in rainbow trout

    Creator:
    Zahr, Camille Reda
    Abstract:
    Temperature influences the incidence of chemically induced cancer in fish, with warmer temperatures being associated with higher cancer incidence. The mechanisms of temperature-modulated chemical carcinogenesis in fish, however, have not been described in detail. Therefore, one primary objective of this study was increased understanding of how temperature-modulated genotoxicity of 7,12-...

  • Human Alteration of a Neotropical Landscape Drives Long-term Changes in its Forest Bird Communities

    Creator:
    Curtis, Jenna R.
    Abstract:
    Human alteration of natural landscapes leads to biodiversity loss, often from a combination of area effects and fragmentation effects. Smaller habitat patches support fewer species than large ones and incur additional consequences from isolation. Efforts to preempt biodiversity loss from insular habitat fragments are complicated by individualistic species responses and...

  • Approaches to the synthesis of polyketides. Vermiculine

    Creator:
    Kirkemo, Curtis Lee
    Abstract:
    An approach to the generation of polyketides was investigated, which involved ozonolysis of 6, 7 cyclopenteno -1> 4, 5, 8 -tetrahydromethoxy- 3-methylnaphthalene (26), to produce what is believed to be polyketide 27. Compound 26 was formed by the following sequence: Die ls -Alder addition of 1, 2 -dim.ethylenecyclopentane and 2...

  • Light detection and ranging (LiDAR) : what we can and cannot see in the forest for the trees

    Creator:
    Edson, Curtis B.
    Abstract:
    Recently concerns over anthropogenic carbon pollution have received increased global attention and research in forest biomass and carbon sequestration has gained momentum. Light Detection and Ranging (LiDAR) remote sensing has in the last decade demonstrated forest measurement and biomass estimation potential. The project objective was to compare LiDAR forest biomass...

  • Evidence for the involvement of a mitochondrial permeability transistion in a victorin-Induced cell death

    Creator:
    Curtis, Marc James
    Abstract:
    Production of the host selective toxin victorin is causal to pathogenesis of Cochliobolus victoriae on oats. The dominant Vb gene confers oat sensitivity to victorin, and is genetically inseparable from Pc2, which confers resistance to Puccinia coronata f. sp. avena. Victorin induces apoptotic-like cell death, and cell death is a...

  • The fine structure of the arthrobranch of the crayfish, Pacifastacus leniusculus Dana, with special reference to active ion uptake

    Creator:
    Morse, Howard Curtis
    Abstract:
    The gills of an Oregon crayfish, Pacifastacus leniusculus Dana, were examined with histological and histochemical techniques and their fine structure was investigated by electron microscopy. Special attention was given to the structural basis of active ion uptake. The histology of these gills was the same as that of other crayfish...
