  • A nonlinear shallow water wave equation and its classical solutions of the cauchy problem

    Creator:
    Crow, John A.
    Abstract:
    A nonlinear wave equation is developed, modeling the evolution in time of shallow water waves over a variable topography. As the usual assumptions of a perfect fluid and an irrotational flow are not made, the resulting model equation is dissipative due to the presence of a viscous boundary layer at...

  • Characteristics of soil organic matter in two forest soils

    Creator:
    Crow, Susan E.
    Abstract:
    Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...

  • John Fiske's philosophy of science : the union of science and religion through the principle of evolution

    Creator:
    Lester, Jacob Franklin
    Abstract:
    Modern science was produced by a Christian society, and although science has had an effect on Christianity, it could not itself remain unaffected. In the second half of the nineteenth century, the subject of evolution was as much a religious as a scientific issue. The battle line was drawn and...

  • John Archibald Wheeler : a study of mentoring in modern physics

    Creator:
    Christensen, Terry M.
    Abstract:
    This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

  • John Wesley Powell : science and reform in a positive context

    Creator:
    Zernel, John Joseph, 1945-
    Abstract:
    John Wesley Powell worked actively for public land system reform while a director of geographical and geological surveys in the West from 1869 to 1894. Although this has won him acclaim as a conservationist, the basis of Powell's linkage of reform with scientific work is poorly understood. A study of...

  • Influences of riparian canopy on aquatic communities in high desert streams of eastern Oregon

    Creator:
    Tait, Cynthia K.
    Abstract:
    Because riparian canopy controls most energy inputs to stream ecosystems, it directly affects the structure of aquatic food webs and the ecological processes that govern interactions among trophic levels. This study addresses the interdependence among riparian canopy, benthic community structure, and the carrying capacity of high desert streams for salmonid...

  • Ecological relationships of birds in forests of western Oregon

    Creator:
    Anderson, Stanley H.
    Abstract:
    The avifaunal composition of ten western Oregon forest stands located at the eastern base of the Coast Range was examined on a seasonal basis. The stands were dominated by Oregon white oak, Douglas fir or western hemlock, Avian populations were sampled monthly from January 1968 to January 1970, using permanent...

  • Reconstructing the paleobiology of the dinosaurs

    Creator:
    Geist, Nicholas R.
    Abstract:
    Dinosaurs represent one of the most successful evolutionary radiations of terrestrial vertebrates, with a myriad of forms that dominated the terrestrial environment for over 180 million years. Despite the fact that dinosaurs are the focus of extensive popular and scholarly investigation, relatively little is actually known of their biology. The...

  • Nasal turbinates and the evolution of mammalian endothermy

    Creator:
    Hillenius, Willem J.
    Abstract:
    Although endothermy is one of the most significant evolutionary developments in the vertebrates, its origins among extinct taxa have traditionally been difficult to determine. Endothermy is primarily an attribute of the "soft anatomy," and its key features, such as complex lungs, elevated blood oxygen carrying capacity and mitochondrial density, do...
