    Antimicrobial susceptibility of sixty human fecal isolates ofAeromonas species (1989)
    Springer
    European journal of clinical microbiology & infectious diseases 8 (1989), S. 248-250

    Notes: Abstract The MICs of 21 antimicrobial agents were determined for 60 strains ofAeromonas spp. isolated from human feces. All isolates tested were susceptible to aztreonam, tetracycline, imipenem, moxalactam, pipemidic acid, gentamicin, trimethoprim-sulfamethoxazole, pefloxacin and ciprofloxacin. Resistance to erythromycin and streptomycin was observed in all 60 strains.Aeromonas caviae was less susceptible to cefamandole, cefotaxime, norfloxacin, chloramphenicol, tetracycline, sulfamethoxazole and trimethoprim than was eitherAeromonas hydrophila orAeromonas sobria. It was concluded that cotrimoxazole or one of the newer quinolones can be considered for treatment of aeromonas-associated diarrhea.

    Finite element stream function-vorticity solutions of the incompressible Navier-Stokes equations (1987)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 7 (1987), S. 17-27 
    Details
    ISSN: 0271-2091
    Keywords: Finite Element ; Navier-Stokes Stream ; Function Vorticity ; Engineering ; Engineering General

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: The incompressible, two-dimensional Navier-Stokes equations are solved by the finite element method (FEM) using a novel stream function/vorticity formulation. The no-slip solid walls boundary condition is applied by taking advantage of the simple implementation of natural boundary conditions in the FEM, eliminating the need for an iterative evaluation of wall vorticity formulae. In addition, with the proper choice of elements, a stable scheme is constructed allowing convergence to be achieved for all Reynolds numbers, from creeping to inviscid flow, without the traditional need for upwinding and its associated false diffusion. Solutions are presented for a variety of geometries.

    Finite element solution of the incompressible Navier-Stokes equations by a Helmholtz velocity decomposition (1991)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 13 (1991), S. 135-144 
    Details
    ISSN: 0271-2091

    Notes: Finite element solution methods for the incompressible Navier-Stokes equations in primitive variables form are presented. To provide the necessary coupling and enhance stability, a dissipation in the form of a pressure Laplacian is introduced into the continuity equation. The recasting of the problem in terms of pressure and an auxiliary velocity demonstrates how the error introduced by the pressure dissipation can be totally eliminated while retaining its stabilizing properties. The method can also be formally interpreted as a Helmholtz decomposition of the velocity vector.The governing equations are discretized by a Galerkin weighted residual method and, because of the modification to the continuity equation, equal interpolations for all the unknowns are permitted. Newton linearization is used and at each iteration the linear algebraic system is solved by a direct solver. Convergence of the algorithm is shown to be very rapid. Results are presented for two-dimensional flows in various geometries.

    Finite element method in the solution of the Euler and Navier-Stokes equations for internal flow (1991)
    New York, NY [u.a.] : Wiley-Blackwell
    Numerical Methods for Partial Differential Equations 7 (1991), S. 193-207

    Notes: Finite element solutions of the Euler and Navier-Stokes equations are presented, using a simple dissipation model. The discretization is based on the weak-Galerkin weighted residual method and equal interpolation functions for all the unknowns are permitted. The nonlinearity is iterated upon using a Newton method and at each iteration the linear algebraic system is solved by a direct solver with all unknowns fully coupled. Results are presented for two-dimensional transonic inviscid flows and two- and three-dimensional incompressible viscous flows. Convergence of the algorithm is shown to be quadratic, reaching machine accuracy in very few iterations. The inviscid results demonstrate the existence of nonunique numerical solutions to the steady Euler equations.
