  • Crop and tree response to planting patterns in alley cropping systems

    Creator:
    Seiter, Stefan
    Abstract:
    Growing trees as a green manure crop together with an annual food crop is a new technology for farmers in Oregon. To promote farmer participation and to acquire a broad knowledge of the processes involved in species interactions, three feasible alley cropping and two sweet corn monocrop planting patterns were...

  • Soil temperature suppression on growth and yield of potato (Solanum tuberosum L.) in warm climates of Sri Lanka

    Creator:
    Tharmarajah, S. K.
    Abstract:
    Potato (Solanum tuberosum L.) is one of the most productive and nutritious food crops. Due to its adaptability to cool climates, production in Sri Lanka has been restricted to erosion-prone highlands. Vast potential exists for expansion of potato cultivation in the lowlands while production areas in the highlands are limited...

  • Cereal residue effects on weeds and cucumbers

    Creator:
    Peachey, Ronald Edward
    Abstract:
    Cereal residues suppress the development of small seeded, summer annual weeds. The focus of this study was to determine whether cereal residues can be used to suppress weeds in cucumber production systems in the Pacific Northwest. In the first of three experiments, cereal residues of fall-planted, spring-killed cover crops suppressed...

  • Multiple pest suppression with cover crops in strawberry

    Creator:
    Datta, Braja Bandhu
    Abstract:
    The experiment was conducted to compare multiple pest (weed, soil arthropod and diseases) suppression by cereal cover crops in 'Selva' and 'Totem' strawberry. In addition, perlite was used to compare improvement of soil and root aeration which might modify strawberry black root rot complex. Small-seeded summer annual weeds were suppressed...

  • On-farm inquiry and assessment of tillage and cover cropping for white mold control in snap bean production

    Creator:
    Harrison, Elizabeth Langham.
    Abstract:
    Cultural practices in snap bean production were evaluated at the Oregon State University Vegetable Research Farm Corvallis, Oregon. In addition, decision-making in snap bean production was assessed on five farms in the Coburg-Junction City-Harrisburg regions of the Willamette Valley, Oregon. A field experiment with cover crop and tillage techniques was...

  • Managing growth and competition of a perennial ryegrass (Lolium perenne L.) living mulch in a vegetable cropping system

    Creator:
    Wiles, Lori Jeannine
    Abstract:
    Vegetable production with a living mulch may reduce soil erosion and compaction, increase organic matter levels, and decrease the requirement for chemical inputs. Competition between the vegetable and mulch, however, has limited the development of successful living mulch systems to realize these benefits. In a field study, interference between pak...

  • Patient Compliance Effects on Simulated Ebola Medical Care Delivery with a Telepresence Robot

    Creator:
    Brian, Makenzie M.
    Abstract:
    When treating highly infectious diseases, patient compliance with caregiver recommendations is crucial. Many patients who contract Ebola Virus Disease have symptoms including vomiting and severe diarrhea and die from the resulting dehydration if they do not drink enough fluids. Telepresence robots are useful in the context of Ebola treatment for...

  • Destabilization of a Stratified Shear Layer by Ambient Turbulence

    Creator:
    Li, Lin
    Abstract:
    A small eddy viscosity or mass diffusivity that varies with height has been found to have unexpected effects on the Kelvin-Helmholtz (KH) instability of a stably stratified shear layer near the neutral stability boundary. In particular, varying viscosity can increase the growth rate of the instability in contrast to the...

  • Initial Designs for Improving Conversations for People Using Speech Synthesizers

    Creator:
    Nguyen, Duy M.
    Abstract:
    This thesis aims to determine the impact that Augmentative and Alternative Communication (AAC) devices have on social interactions, and then improves the AAC user experience through a user focus design process. AAC devices enable people who cannot speak to communicate with others. Unfortunately, they are tedious to use and make...

  • Robots Against Infectious Diseases : A Technologically Grounded, Human-Centered Exploration

    Creator:
    Kraft, Kory
    Abstract:
    Robots have the potential to protect health care workers, provide patient care, and ultimately save lives in infectious disease outbreaks. Nevertheless, infectious disease outbreak scenarios present unique technological and social challenges for robotics. This work explores what robots can and should do in the fight against infectious diseases. We present...
