  • Electro-magneto-hydrodynamics : the processes of electric arc steelmaking

    Creator:
    King, Paul E. (Paul Everson), 1962-
    Abstract:
    Because of competition from abroad, the U. S. Steel industry has begun research into the processes involved with electric arc steelmaking. This paper addresses the mathematical background of these furnaces and the electro-magneto- hydrodynamical effects used to melt the large quantities of steel. A classical approach to the derivation of...

  • Accident analysis of traffic accidents involving radioactive materials (RAM)

    Creator:
    Humphries, Larry LaRon
    Abstract:
    The extensive and expanding use of radioactive materials (RAM) in the production of power, industry, the healing arts, and various branches of research has inevitably resulted in a sizable increase of hazardous material transportation in the state of Oregon. The location of the Hanford facility just north of the Oregon...

  • Hydrophobicity of Cindery Typic Cryorthents

    Creator:
    Evans, Lynn B.
    Abstract:
    The hydrophobicity of soils of the Deschutes National Forest was studied. The soils are Cindery Typic Cryorthents, formed in cinders and ash from Mt. Mazama. Ponderosa pine is the dominant overstory vegetation. Of particular interest was the effect of prescribed burning on hydrophobicity. Fire has been shown to cause a...

  • A relationship between wave dispersion and fracture strength for a composite material

    Creator:
    Ilcewicz, Larry Bert
    Abstract:
    Wave dispersion and fracture are phenomena that involve. mechanisms triggered at the scale of a material's internal structure. Experiments were performed with a candidate material to judge the hypothesis that wave dispersion measurements can be used to nondestructively predict fracture strength. Wood-based particleboard was chosen as the candidate material because...

  • Simulation and field validation of heat and water flow during soil freezing and thawing

    Creator:
    Pikul, Joseph Lawrence
    Abstract:
    Freeze/thaw cycles are numerous in agricultural soils of the Pacific Northwest. Potential loss of soil by erosion is high whenever a soil thaws from the surface creating a saturated soil overlying an impermeable frozen layer. Field studies were conducted to investigate the effect of surface residue on soil freezing. Residue...

  • Turbulent structure in the bora and stable boundary layer

    Creator:
    Frank, Helmut P.
    Abstract:
    An eigenvector analysis of the velocity-temperature correlation matrix is applied to clear-air turbulence measured by aircraft in the Bora. The eigenvectors are identified with the main eddies of the turbulence. This study attempts to infer the three-dimensional structure of these eddies. The results are compared with turbulent structures in the...

  • Structure of turbulence in stratified flow : aircraft data from SESAME and ALPEX

    Creator:
    Gamage, Nimal K. K.
    Abstract:
    Several horizontal flight segments from SESAME and ALPEX are studied using structure functions and specral analysis methods. Theoretical analysis of the relative errors in structure function and correlation function in the presence of large scale wave activity is presented. The effect of stratification and shear on the -5/3 inertial subrange...

  • Diffusion of oxygen and carbon dioxide through soil with temperature and water content effects on sink/source strength

    Creator:
    Ying, Ouyang
    Abstract:
    Gaseous diffusion equations which describe the diffusion of oxygen and carbon dioxide through soil have been studied by several investigators. However, these efforts seldom considered gaseous diffusion through soil together with the effects of soil environmental factors such as soil temperature and soil water content on sink or source strength....

    Creator:
    Tobbi, Belgacem
    Abstract:
    The purpose of this study was to use computer analysis of soil and rainfall data to predict the possible occurrence of soil erosion in Central Tunisia. Analysis was done with the program OR-NATURE (M.Ungs et al, 1985) . Central Tunisia was subdivided into northern, central, and southern subzones. Data about...

  • Stability analysis of homogeneous shear flow : the linear and nonlinear theories and a Hamiltonian formulation

    Creator:
    Hagelberg, Carl R.
    Abstract:
    The stability of steady-state solutions of the equations governing two-dimensional, homogeneous, incompressible fluid flow are analyzed in the context of shear-flow in a channel. Both the linear and nonlinear theories are reviewed and compared. In proving nonlinear stability of an equilibrium, emphasis is placed on using the stability algorithm developed...
