  • Science and technology in cutting-edge agricultural biotechnology research

    Creator:
    Xia, Yin
    Abstract:
    The genetic engineering made possible by the discovery of recombinant DNA has played an increasingly important role in agricultural research. The present study employs a knowledge production model to assess the efficacy of, and relationship between, basic and applied research in agricultural biotechnology, allowing for both complementarity and substitutability between...

  • In search of ecological advantages : Mycorrhizal facilitation of big huckleberry Vaccinium membranaceum (Doug.)

    Creator:
    Stocking, Peter
    Abstract:
    Temperate evergreen forests of the Pacific Northwest support big huckleberries (Vaccinium membranaceum) despite their nutrient impoverished soils. Acquisition of nitrogen and phosphorous are the major nutrients limiting V. membranaceum. The plant’s access to these resources is linked to their mycorrhizal symbiosis. To learn more about the symbionts of eriaceous plants...

  • Contributions to Collaborative Filtering Research

    Creator:
    Nong, Shuzhen
    Abstract:
    In this report, I first introduce three areas of interest to collaborative filtering researchers, namely: (a) how to solve the sparsity and scalability problems in recommendation systems; (b) how to rapidly develop and test collaborative filtering algorithms; and (c) how to apply collaborative filtering to unbounded numeric preference data. In...

  • Communicating the wildland fire message : an investigation of agency outreach strategies

    Creator:
    Toman, Eric Lee
    Abstract:
    Wildfire impacts have increased in recent years. The management response outlined by recent policy initiatives (e.g., the National Fire Plan, Healthy Forests Restoration Act) emphasizes the use of prescribed fire and mechanized thinning to reduce the risk of future fire events. These policies also call for an unprecedented level of...

  • Stability of reporter gene expression and RNAi in transgenic poplars over multiple years in the field under vegetative propagation

    Creator:
    Li, Jingyi
    Abstract:
    Stable expression of transgenes is required for commercial uses of genetically engineered trees. To better understand the stability of transgene expression under field conditions, we studied transgene expression and RNA interference (RNAi)-induced transgene suppression in 2,480 transgenic poplars (460 transgene insertion events) over three years. Stability of expression was assessed...

  • The ecological legacy of Indian burning practices in southwestern Oregon

    Creator:
    Carloni, Kenneth R.
    Abstract:
    Two research questions are posed: (1) How have ecosystem conditions changed through time in southwestern Oregon? (2) How have culture-driven and climate-driven processes contributed to ecosystem change in southwestern Oregon? A brief introduction to the Little River study area is followed by a cultural and ecological history of the watershed....

  • Gas injection consolidation of miniature natural fiber beams

    Creator:
    Kim, Jae-Woo
    Abstract:
    The internal structure of natural fiber composites can be manipulated by controlling the spatial distribution of fiber orientation and internal chemical and thermodynamic conditions during their consolidation. Objects highly tailored to specific service demands may thereby be produced. Techniques to form miniature structural beams from oriented hemp and random wood...

  • Micropropagation of Douglas fir (Pseudotsuga menziesii) in a double-phase culture medium

    Creator:
    Gross, Leah M.
    Abstract:
    The timber and Christmas tree industries are important components of the Pacific Northwest economy. A goal of both industries is to produce high quality trees with high growth rates. Accomplishing this requires increased genetic quality of the trees grown. Tissue culture provides the most promise for propagating these superior genotypes....
