  • Studies on the metabolism on n-propyl N, N-di-n-propyl thiolcarbamate in legumes

    Creator:
    Bourke, John Butts
    Abstract:
    The absorption, translocation and metabolism of a new herbicide, n-propyl-C¹⁴ N, N-di-n-propyl-thiolcarbamate (PDPC), were studied in both peanut and soybean plants. These studies were carried out on plants of different ages and treated at two rates of application. The residue content of the plants was also determined from germination to...

  • Some biochemical studies of phenylmercuric acetate and mercuric acetate toxicity in rats

    Creator:
    Ellis, Robert William
    Abstract:
    Biochemical studies of phenylmercuric acetate (PMA) and mercuric acetate toxicity in rats carried out during this investigation were (1) the metabolism of ²⁰³Hg(Ac)₂ and ²⁰³Hg-PMA within kidney and liver tissues following oral ingestion, (2) the effect on some soluble enzyme activities and determinations of ²⁰³Hg binding in the enzyme fractions,...

  • Nonlinear oscillations, bifurcations and chaos in ocean mooring systems

    Creator:
    Gottlieb, Oded
    Abstract:
    Complex nonlinear and chaotic responses have been recently observed in various compliant ocean systems. These systems are characterized by a nonlinear mooring restoring force and a coupled fluid-structure interaction exciting force. A general class of ocean mooring system models is formulated by incorporating a variable mooring configuration and the exact...

  • Stochastic analysis of a nonlinear ocean structural system

    Creator:
    Lin, Huan
    Abstract:
    Stochastic analysis procedures have been recently applied to analyze nonlinear dynamical systems. In this study, nonlinear responses, stochastic and/or chaotic, are examined and interpreted from a probabilistic perspective. A multi-point-moored ocean structural system under regular and irregular wave excitations is analytically examined via a generalized stochastic Melnikov function and Markov...

  • Deterministic and stochastic behaviors of a piecewise-linear system

    Creator:
    Mha, Ho-Seong
    Abstract:
    The (nonlinear) response behavior of a piecewise-linear system is investigated under both deterministic and stochastic excitations in this study. A semi-analytical procedure is developed to predict the system behavior by evaluating the joint probability density functions of the Fokker-Planck equations of the stochastic piecewise-linear system under random excitations via a...

  • Seismic protection of flexible rotating machines using base isolators

    Creator:
    Su, Wen-Chyi
    Abstract:
    Base isolation is an alternative seismic design strategy in which the primary structures and their internal components are uncoupled from the potentially damaging horizontal components of an earthquake by base isolators which attenuate the transmission of horizontal acceleration into the system. Rotating machines are among the key internal components of...

  • Stochastic analysis of complex nonlinear system response under narrowband excitations

    Creator:
    Shih, I-Ming
    Abstract:
    Response behavior of a nonlinear structural system subject to environmental loadings is investigated in this study. The system contains a nonlinear restoring force due to large geometric displacement. The external excitation is modeled as a narrowband stochastic process possessing dynamic characteristics of typical environmental loadings. A semi-analytical method is developed...
