  • Gene expression, genome organization, and evolution of the Orgyia pseudotsugata multicapsid nuclear polyhedrosis virus

    Creator:
    Leisy, Douglas J.
    Abstract:
    The genome of the multicapsid nuclear polyhedrosis virus of Orgyia pseudotsugata (OpMNPV) was mapped by examining overlapping Hindlll fragments from cosmid clones which had been constructed from partial Hindlll digests of viral DNA. Five OpMNPV cosmid clones containing fragments encompassing the entire OpMNPV genome were hybridized to blots of DNA...

  • Hypervelocity spectroscopy from impacts in polymeric materials

    Creator:
    Buettner, Douglas J.
    Abstract:
    Stacked sheets of polyethylene terephthalate andpolystyrene provide a means for recovering projectiles travelling at hypervelocities. The transparency of these multiple diaphragms is utilized so that light generated from hypervelocity impacts can be studied. A method for gathering visible as well as ultraviolet light from less transparent polymer foams has been...

  • Using p-adic valuations to decrease computational error

    Creator:
    Limmer, Douglas J.
    Abstract:
    The standard way of representing numbers on computers gives rise to errors which increase as computations progress. Using p-adic valuations can reduce error accumulation. Valuation theory tells us that p-adic and standard valuations cannot be directly compared. The p-adic valuation can, however, be used in an indirect way. This gives...

  • Determinants of off-farm labor supply among farm households in the north Willamette Valley

    Creator:
    Doyle, Douglas J., 1963-
    Abstract:
    Financial stress in agriculture has been a concern over the past century. Agrarian values and "love of the land" seem to yield public conclusions for the support of the industry. Much of this support is in the interest of preserving a viable food producing sector in an volatile world climate....

  • Measure-equivalence of quadratic forms

    Creator:
    Limmer, Douglas J.
    Abstract:
    This paper examines the probability that a random polynomial of specific degree over a field has a specific number of distinct roots in that field. Probabilities are found for random quadratic polynomials with respect to various probability measures on the real numbers and p-adic numbers. In the process, some properties...
