    Effects of temperature on food ingestion rate and absorption, retention, and equilibrium burden of phosphorus in an aquatic snail, Goniobasis clavaeformis Lea (1975)
    Oxford, UK : Blackwell Publishing Ltd
    Freshwater biology 5 (1975), S. 0

    Topics: Biology
    Notes: The effects of sublethal temperatures on feeding rates and phosphorus dynamics of a freshwater snail, Goniobasis clavaeformis Lea, were determined and feeding rates were measured at four temperatures. The food source was aufwuchs labelled with radioactive phosphorus. A model was developed to elucidate the results of this type of study. Food ingestion rate increased with increasing temperature up to 14°C and then decreased at temperatures above 14°C. The elimination rate of absorbed phosphorus increased with increasing temperature throughout the entire range of experimental temperatures, 10-19.3°C. Mean retention times of absorbed phosphorus i n Goniobasis were estimated to be 34, 24, 10, and 6 days at 10, 13.8, 15, and 193°C, respectively. Mean retention time of unabsorbed 32P in the gut of this species as a function of temperature followed the same temperature relationship as that of ingestion rate.The absorption efficiency of phosphorus was estimated to be constant at about 39% for ail experimental temperatures, although the data suggest that the absorption ePRciency may have been related inversely to the rate of gut clearance or directly to the residence time of food in the gut. The equilibrium body load of phosphorus at each experimental temperature was estimated based on concentrations of stable phosphorus in the food source and the kinetics of 32P in Goniobasis. The equilibrium body burden of phosphorus in Goniobasis increased with increasing temperatures up to a maximum at 11–12°C and then decreased at temperatures above 12°C.

    Laser Doppler measurement of turbulence parameters in a two-dimensional plane wall jet (1994)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 6 (1994), S. 3116-3129

    ISSN: 1089-7666

    Topics: Physics
    Notes: A computer-controlled data acquisition system has been designed and constructed to automate measurement of turbulent velocity correlations in a two-dimensional turbulent wall jet. Measurements are made with a single component laser Doppler velocimeter system in a flow of air on a flat plate with stagnant surroundings. Measurements of a number of turbulence parameters have been completed and compared with existing hot-wire data. The measurements are made at two downstream locations at a Reynolds number, based on slot width, of 14 000. Earlier hot-wire data for a two-dimensional turbulent wall jet in stagnant surroundings show much scatter in the outer region where local turbulence intensities range from 40% to 70%. The laser Doppler velocimeter gives repeatable values and eliminates the bias in hot-wire measurements due to reversing flow and errors in corrections for high turbulence effects. The measured turbulent normal stresses are somewhat higher than those previously reported throughout the flow field. The turbulent shear stress is in good agreement with previous hot-wire results near the wall. Hot wires are shown to indicate low values of the Reynolds stress in the turbulent outer regions where they are affected by strong flow reversals. The new measurements agree well with predictions based on momentum integral methods.

    Electronic structure of the NaN2 and NaC2H2 collision complexes: Experiment and theory (2001)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The electronic structure of the NaN2 and NaC2H2 collision pairs is probed by optical excitation. Based on polarization experiments, we measure the alignment tensor of the electronic transition dipole moments. We compare the experimental data with the results of a quantum chemical calculation. The different geometric properties of the electronic wave functions of the two collision pairs are directly visible in the experimental data. © 2001 American Institute of Physics.

    A MODEL FOR THE BEHAVIOUR OF MATERIALS WITH CRACKS UNDER HYDROGEN EMBRITTLEMENT CONDITIONS (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Fatigue & fracture of engineering materials & structures 20 (1997), S. 0 
    Details

    Notes: Abstract— We consider the slow growth of normal tension cracks as quasi-brittle behaviour under hydrogen embrittlement conditions. Experiments show that the cracking resistance of a material in such cases is not a constant of the material, but is characterized by some function that relates the rate of crack growth to the stress intensity factor. We propose a numerical method for the calculation of opening mode crack growth when the kinetics are controlled by the gas diffusion into the material. The problems under consideration model the fracture phenomena inherent to structures (e.g. pressure vessels, pipelines) that operate in an aggressive medium and in particular a hydrogen environment.In such problems it is necessary to calculate the pressure variation inside a crack as a result of gas diffusion and crack growth under the action of this pressure. Hence it is necessary to solve problems of diffusion theory and elasticity theory for a cracked medium together with some additional conditions that provide the link between these two fundamental problems.We study the case of an infinite medium containing a crack which occupies a plane domain of arbitrary shape. To avoid difficulties related to the three-dimensionality of the problems, we reduce them to two-dimensional integro-differential equations for the crack domain. The integro-differential equation of the elasticity problem of the crack is solved on the basis of the Boundary Element Method (BEM). The crack kinetics are calculated using a scheme previously introduced by one of the authors and then the BEM is used to solve the integral equation for the diffusion-into-the-crack problem similar to the analogous problem of filtration of the fluid into a crack.

    Integrity of pressurized components with localized corrosion under internal pressure and transient thermal loading (2003)
    PO Box 1354, 9600 Garsington Road , Oxford OX4 2XG , UK . : Blackwell Science Ltd

    Notes: This paper is devoted to the modelling and analysis of the problem of the safety and residual lifetime of pressurized components (e.g. pressure vessels, apparatus, pipelines) with zones of local corrosion damage. Corrosion damage is the most common form of structural material degradation in service conditions, in particular, in the chemical and gas, and oil industries. Attention is paid to nonstationary regimes of the component operation, e.g., start-stop regimes. It is shown that the critical parameters calculated taking into account the nonstationary loading can be lower compared with ones determined for the stationary regimes, e.g., on the basis of the ASME Code B31G.
