  • Jerking behavior among phytoseiid mite species (Acari: Phytoseiidae)

    Creator:
    Blackwood, J. Scott
    Abstract:
    Jerking, which we defined as a pronounced and often repeated lunging of the entire body, was studied in larvae among seven species of phytoseiid mites, and in the nymphal stages of Neoseiulus fallacis (Garman). This behavior was observed in all active immature stages of N. fallacis, and in larvae of...

  • Evaluation of total hip arthroplasty research in the US and Europe

    Creator:
    Simmons, Marcy J.
    Abstract:
    Background: Hip replacements are considered routine operations which improve the quality of life in patients by reducing pain and restoring function. There are many variations in prostheses with varying benefits and disadvantages. Methods: Literature from the United States and Europe was collected on total hip replacements between 2001 and the...

  • Prey-stage preference in phytoseiid mites

    Creator:
    Blackwood, J. Scott
    Abstract:
    Knowledge of how individual organisms behave in their environment can provide a greater understanding of population dynamics. In a predator-prey system, the choices made by predators when foraging for prey are important aspects of behavior. Particularly in the case of a stage-structured prey population, how the predator selects prey stages...

  • Functional imaging reveals modest strain concentrations associated with implant micromotion using modified BAK interbody cages

    Creator:
    Berry, Daniel J.
    Abstract:
    Interbody fusion cages are increasingly used in the treatment of spinal disease and injury in order to stabilize movement and promote arthrodesis of the vertebral bodies, but the micro-mechanics of the interaction between the cage and the adjacent host bone is not fully understood. This information has bearing on post-surgical...

  • U(VI) transport in subsurface materials: is two-site, one-species modeling sufficient?

    Creator:
    Harrington, Stephanie J.
    Abstract:
    Uranium adsorption to Hanford sediment was studied for various pH, total inorganic carbon concentrations, and total U(VI) concentrations. Both batch and transport studies were done in an attempt to understand the adsorptive trend of U(VI) on Hanford sediment, and the changes in adsorption as both pH and total inorganic carbon...

  • Factors associated with the implementation fidelity of a school-based social and character development program : findings from the Positive Action program, Hawai’i

    Creator:
    Beets, Michael W.
    Abstract:
    Implementation fidelity (dosage, adherence, quality of delivery, responsiveness, program differentiation) is the degree to which a program was carried out to its original intent. The following three studies examined the implementation fidelity of a school-based health promotion social and character development (SACD) program. The, Positive Action (PA) program was a...

  • Sources of flow maldistribution in microreactor-assisted synthesis of ceria nanoparticles

    Creator:
    Tseng, Chih-Heng
    Abstract:
    Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...

  • Biological control of spider mites (Acari: Tetranychidae) on grape emphasizing regional aspects

    Creator:
    Prischmann, Deirdre A.
    Abstract:
    During summer of 1998 and 1999, 34 and 10 vineyard sites, respectively, were sampled to assess spider mite pests and associated biological control by phytoseiid mites. Vineyards studied spanned five major valleys in western Oregon where grape production occurs. Leaf samples were taken from site perimeters and centers. One leaf...

  • Thermal hydraulic analysis of the Oregon State TRIGA Reactor using RELAP5-3D

    Creator:
    Marcum, Wade R.
    Abstract:
    Oregon State University has recently conducted a complete core conversion analysis as part of the Reduced Enrichment for Research and Test Reactors Pprogram. The goals of the thermal hydraulic analyses were to calculate natural circulation flow rates, coolant temperatures and fuel temperatures as a function of core power for both...

  • An internal convective heating technique for diffusion bonding highly parallel microchannel architectures

    Creator:
    Bose, Sumantra
    Abstract:
    Diffusion bonding cycle times can be a large cost factor in the production of metal microchannel devices. The challenge is to significantly minimize this cost by reducing the bonding cycle time through rapid and uniform heating and cooling within the bonding process. Heating rates in diffusion bonding processes are typically...
