  • The detection of ilarvirus (subgroup B) by enzyme-linked immunosorbent assay

    Creator:
    McMorran, Jeffrey P.
    Abstract:
    The reliability and sensitivity of enzyme-linked immunosorbent assay (ELISA) in the detection of ilarvirus (isometric labile ringspot virus) subgroup B and prune dwarf virus (PDV) isolates in Prunus and Malus species has been well established. To use this technique in large scale virus indexing programs more information was required on...

  • Effect of intervention strategies on specific verbal feedback of volunteers and its secondary effect on qualitative motor performance

    Creator:
    Gately, Jeanne E.
    Abstract:
    The purpose of this study was twofold. First, to determine if planned interventions could increase untrained undergraduate students' use of positive and specific skill feedback while a teaching fundamental motor skill to children who are disabled. Second, to qualitatively assess the effect of specific verbal feedback on student motor performance....

  • Performance and graphics enhancement of the LOGSIM mechanized log harvesting system simulator

    Creator:
    Moss, J. Alexander
    Abstract:
    The focus of this research concentrates on enhancement of the LOGSIM mechanized log harvesting system simulator. Enhancement of software focuses on overall improvement of the user environment as well as improvement of the performance and capabilities of the simulation package. An enhanced version of the front-end interface program is developed...

  • 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...

  • FeagaJeff2004.pdf

    Feaga, Jeff
    Abstract:
    The Willamette Valley of Oregon has high rates of winter precipitation that cause leaching losses of residual fertilizer nitrogen (N) as nitrate (NO₃). Cover crops may have potential to mitigate N loss. Shallow groundwater was sampled for 11 years from plots planted in summer vegetables with and without winter cover...

    Abstract:
    The Upper Devonian Fenstermaker Limestone is a thickening-upward sequence of interbedded sandy intrapelsparite and subordinate calcareous siltstone and mudstone which averages 190 ft (58 m) thick in the northern Antelope Range. The Fenstermaker Limestone is revised and restricted herein to include only those rocks above a basinal shale sequence of...

  • Fiber optic sensors and spectrometry for the detection of volatile gem-polyhalogenated hydrocarbons

    Creator:
    Louch, Jeff
    Abstract:
    A fiber optic fluorometer utilizing a double-fiber optic probe was constructed. The absolute fluorescence signal and effective collection efficiency are approximately one fifth those of typical cuvette fluorometers and agree with those predicted by theory. A quinine sulfate calibration curve shows linearity from a detection limit of 10 pg/mL to...
