  • Enhanced sensors for vehicle dynamics evaluation

    Creator:
    Baratange, Francois
    Abstract:
    Vehicle dynamics evaluation is divided in two domains: ride quality and handling. The evaluation of characteristics related to both of these domains requires the knowledge of the vibrations developed by the vehicle. Vibrations can be described by acceleration, velocity or displacement (linear or angular). The inertial properties of large vehicles...

  • Production and export of biogenic silica in the Southern Ocean

    Creator:
    Sigmon, Daniel E.
    Abstract:
    Dissolved silicic acid (Si(OH)4) and biogenic silica (BSiO2) concentrations were measured on four different cruises in the Southern Ocean along 1700 W from late October 1997 to mid-March 1998. These data were used to construct a vertically integrated Si budget in the surface layer from 58° to 68° S. Throughout...

  • Individual Tree Detection and Measurement from Terrestrial Point Cloud

    Creator:
    Qi, Chu
    Abstract:
    Remote sensing forest inventory gained increased attention in the last decade triggered by the decrease in the price of sensors and the explosion of data availability and formats. Evermore, the constant advances in the hardware processing the data emphasized the necessity to develop algorithms to extract forest relevant information from...

  • A study on the effects of enhanced pCO2 on open ocean diazotrophic assemblages

    Creator:
    Gradoville, Mary Rose
    Abstract:
    Biological di-nitrogen (N₂) fixation is a key process in open-ocean ecosystems, where the new nitrogen (N) provided by marine diazotrophs can support a large fraction of primary productivity and carbon (C) drawdown. Recent laboratory studies have shown that elevated pCO₂ enhances the rate of N₂ fixation by select laboratory isolates...

  • Phosphorus availability in biosolids-amended soils

    Creator:
    Choate, Jeff
    Abstract:
    Quantifying labile phosphorus (P) pools in biosolids is needed to manage biosolids for both agronomic and environmental purposes. Phosphorus indices originated in an effort to protect surface water quality from-non-point-agricultural P inputs. The objectives of this research were to: (1) evaluate soil test components of the western Oregon P index...

  • Regulation of inositol phospholipid hydrolysis by extended treatment with angiotensin II in human aortic smooth muscle cells

    Creator:
    Niibori, Yoshiko
    Abstract:
    Long-term stimuli of many systems leads to decreased cellular responsiveness, or desensitization. We characterized the desensitization of angiotensin II (Ang 11)-mediated inositol phospholipid (IP) hydrolysis in cultured human aortic smooth muscle cells (HASMC). Although it has been suggested that the desensitization induced by long-term Mg II exposure may result partially...

  • Maturity and stability evaluation of composted yard debris

    Creator:
    Brewer, Linda J.
    Abstract:
    Compost maturity is an important determinant of end use for composted municipal yard debris, and generally refers to the effect the compost has on plants. The rate of microbial respiration is an indicator of compost stability. The objectives of this research were to: i) determine whether continuous aeration resulted in...

  • Susceptibility of golden chinquapin (Chrysolepis chrysophylla) to Phytophthora cambivora

    Creator:
    Saavedra, Angel Luis
    Abstract:
    In early 2000, unusual mortality of a native North American tree, golden chinquapin, was reported by the USDA-Forest Service. Dying trees exhibited girdling cankers in the inner bark of the lower bole, branch flagging and defoliation. Isolations from necrotic tissues and soil associated with diseased or killed trees yielded Phytophthora...

  • The inhibitory effect of cryteine on Streptomyces griseus phage reproduction

    Creator:
    Nishikawa, Sumie Suzuki
    Abstract:
    Cysteine inhibition of phage multiplication in Escherichia coli has been described by a number of workers. More recently cysteine has been found to lower the yield of Streptomyces griseus phage. The present study sought a more complete description of the "cysteine effect" as it has been noted in the S....
