  • Factors influencing metribuzin use in strip-planted wheat

    Creator:
    Zeghida, Ali
    Abstract:
    Equipment for strip-till planting is under development in wheat-fallow rotations in the Columbia Basin of Oregon. This involves the absence of tillage during the fallow season. At planting time, the strip-till planter creates a narrow band into which the wheat seed is placed. The area between the rows is undisturbed...

  • Evaluation of alternative information signs in Oregon

    Creator:
    Neill, Justin Michael
    Abstract:
    The number of international inbound tourists to the United States has risen steadily. To serve these and other tourists best, traffic signs need to communicate information correctly across a potential language barrier. Of particular interest is the traffic sign intended to communicate directions to Tourist Information centers. While the general...

  • Personalized information management systems with tutorial capabilities

    Creator:
    Oman, Paul W.
    Abstract:
    Technological advances of the last three decades have caused an enormous increase in the amount of published and unpublished information generated by our society. This inflation has created the need for improved information management systems. Existing systems are inadequate primarily because they are discipline-oriented and lack the flexibility that is...

  • Fluid forces on and flow configurations around a circular cylinder near a plane boundary

    Creator:
    Tavolacci, Don
    Abstract:
    The flow configurations around and the forces acting on a circular cylinder with its axis parallel to a nearby plane boundary and subjected to a uniform flow were investigated. The flow conditions, which were perpendicular to the cylinder axis and parallel to the plane boundary were investigated experimentally and theoretically....

  • Structural stability effects on adsorption of bacteriophage T4 lysozyme to colloidal silica

    Creator:
    Tian, Minghua
    Abstract:
    Circular dichroism (CD) spectra were obtained for bacteriophage T4 lysozyme and three of its mutants in the presence and absence of colloidal silica nanoparticles. Mutant lysozymes were produced by substitution of the isoleucine at position 3 with tryptophan, cysteine and leucine. Each substitution resulted in an altered structural stability, quantified...

  • Theoretical physics takes root in America : John Archibald Wheeler as student and mentor

    Creator:
    Christensen, Terry M.
    Abstract:
    John Archibald Wheeler (09 July 1911- ) is a familiar name to physicists and historians of physics alike. Among his many contributions to the corpus of knowledge, in 1939 John Wheeler and Niels Bohr co-authored the first paper on the generalized mechanism of nuclear fission. Beyond that seminal work, Wheeler...

  • Nature in chains : the effects of Thomas Jefferson’s rectangular survey on a Pacific Northwest landscape

    Creator:
    Schweickert, Tina K.
    Abstract:
    Understanding the impact of humans on the environment has long been a topic of scholarly interest and debate. As environmental problems mount, accounts of historic ecological conditions and the factors of change become increasingly useful. This study considers competing schools of interpretation about human impacts on ecological landscapes and develops...

  • In the midst of a revolution : science, fish culture, and the Oregon Game Commission, 1935-1949

    Creator:
    Hahn, Linda
    Abstract:
    This thesis will address the transformation of biological sciences during the 1930s and 1940s and it effects on fisheries science. It will focus on Oregon State College and specifically the Department of Fish and Game Management and the interaction with the Oregon Game Commission. Support for mutation theory and neo-...

  • Geographic information systems : some considerations for use in geographic research and analysis

    Creator:
    Herstrom, Andrew A.
    Abstract:
    The major considerations for acquiring and using a geographic information system (G..I.S.) for regional or national geographical research and analysis are examined in this paper. After defining what a G.I.S. is, some of the more practical and useful functions of a G.I.S. in day-to--day geographical work are outlined. Finally, the...

    Abstract:
    The purpose of this study was to propose recommendations for improved diffusion of clothing information to orthopedically limited adults. A sample of 180 orthopedically limited adults residing in the Willamette Valley of Oregon was selected using mailing lists from the Oregon Governor's Conference for the Handicapped, from Oregon State University...
