  • The developmental cytopathology of Prunus persica Batsch. and P. avium L. infected with X-disease and Albino disease respectively

    Creator:
    Florance, E. R.
    Abstract:
    In 1967, Doi et al. proposed the hypothesis that 'yellows type diseases' are caused by mycoplasma. Since then more than 60 yellows diseases have been associated with mycoplasma-like bodies (MLB) (Maramorosch, 1973). The majority of these associations are based upon electron microscopic observations of mycoplasma-like bodies in situ. However, little...

  • Patterns in coastal marsh vegetation of the Juneau area, Alaska

    Creator:
    Stone, Catherine S.
    Abstract:
    A vegetation study was made of four coastal marshes near Juneau, Alaska. Results confirmed earlier studies' findings in southeast Alaska that communities or assemblages of species can be identified but from marsh to marsh these assemblages appear to have no consistent relationship to each other or to environmental "factors" such...

  • Physiological and organism level endpoints in the beetle pterostichus oblongopunctatus (Coleoptera: Carabidae), inhabiting a gradient of heavy metal pollution

    Creator:
    Stone, David
    Abstract:
    Pollutant body burdens, ability to tolerate supplementary stressors, and biomarkers of physiological stress were investigated in the ground beetle, Pterostichus oblongopunctatus (Coleoptera: Carabidae), inhabiting a gradient of heavy metal contamination in Poland. The central question was to determine if beetles inhabiting polluted habitats incurred costs compared with beetles in less...

  • DNA recovery and identification from stone tool microcracks

    Creator:
    Shanks, Orin C.
    Abstract:
    The studies described here introduce a model for residue preservation on stone tools. They simulate stone tool manufacture in order to define parameters important for the study of DNA residues. Microscopic examination of stone tools has identified microcracks that trap DNA and protein from animal blood cells. Thorough investigation of...

  • Theory and application of vector space similarity measures in computer assisted conceptual design

    Creator:
    Poppa, Kerry R.
    Abstract:
    A number of computational tools now exist to aid in developing conceptual solutions based on a functional description of a design problem. A key limitation of these tools is the way results are organized for presentation to the user. In general, results are an undifferentiated mass of potential solutions. Analysis...

  • A contribution to the development of wide band-gap nonlinear optical and laser materials

    Creator:
    Stone-Sundberg, Jennifer L.
    Abstract:
    The primary focus of this work is on examining structure-property relationships of interest for high-power nonlinear optical and laser crystals. An intuitive and simply illustrated method for assessing the nonlinear optical potential of structurally characterized noncentrosymmetric materials is introduced. This method is applied to materials including common quartz and tourmaline...

  • Essays on behavioral economics

    Creator:
    Cao, Zheng
    Abstract:
    This dissertation consists of two essays that address behavioral economics issues. In first chapter we analyze the effects of psychological pressure on performance using National Basketball Association (NBA) free throw data from the 2002-2003 through 2009-2010 seasons. We find evidence that players choke under pressure – they shoot on average...

  • A design framework for identifying automation opportunities

    Creator:
    Nagel, Robert Lewis, 1982-
    Abstract:
    Since the Industrial Revolution, automated systems have increasingly become a part of everyday life. Automated systems range in scale and scope from simple assists to complete robotic replacements. Inexpensive integrated circuits, sensors and microprocessors have allowed automated systems to become smaller, cheaper and more prevalent. Identifying appropriate opportunities for automation,...
