    Renal cadmium content in the West of Scotland (1983)
    Springer
    Urological research 11 (1983), S. 285-290 
    Details
    ISSN: 1434-0879
    Schlagwort(e): Trace metals ; Cadmium ; Kidney cortex ; Ischaemic heart disease ; Medulla
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary The trace element content of kidneys has been documented in very few international centres. Significant differences can be demonstrated between the cortical and medullary levels of calcium, zinc and cadmium. For the West of Scotland the values for the latter are similar to those found in Scandinavia. There are significantly higher cadmium contents in subjects who smoke and who have evidence of ischaemic heart disease.

    The effects of treatment on the hypercalciuria of chronic cadmium poisoning (1979)
    Springer
    Urological research 7 (1979), S. 285-289 
    Details
    ISSN: 1434-0879
    Schlagwort(e): Cadmium ; Iron ; Bendrofluazide ; Hypercalciuria Hyperzincuria ; Treatment
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary Cadmium induces a variety of effects on kidney tubules including hypercalciuria. This is accompanied by hyperzincuria. The present work shows that both of these biochemical abnormalities can be corrected but where a state of cadmium-induced-anaemia exists urine zinc and calcium excretion do not follow the expected parallel course in response to iron therapy as they do with bendrofluazide.

    Histological and ultrastructural changes in rat kidney following cadmium injection (1977)
    Springer
    Urological research 5 (1977), S. 15-20 
    Details
    ISSN: 1434-0879
    Schlagwort(e): Cadmium ; Kidney ; Ultrastructure
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary Cadmium injection in rats affects the genito-urinary system. The renal effects are generally considered to be mainly tubular. Light microscopy of 29 specimens confirms cellular damage in the glomeruli with changes in glomerular capillaries. Electron microscopic changes in the glomeruli confirm changes in the podocytes, thickening of the basement lamina, the occurrence of electron dense deposits in association with the capillary endothelium with platelet and polymorphonuclear cell accumulations which suggests opening of the endothelial junction of the glomerular vessels.

    APPLICATION OF TOPOLOGICAL OPTIMIZATION TECHNIQUES TO STRUCTURAL CRASHWORTHINESS (1996)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 39 (1996), S. 1383-1403 
    Details
    ISSN: 0029-5981
    Schlagwort(e): crashworthiness ; homogenization ; topology design ; automotive structure optimization ; Engineering ; Engineering General
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Mathematik , Technik allgemein
    Notizen: The topological optimization of components to maximize crash energy absorption for a given volume is considered. The crash analysis is performed using a DYNA3D finite element analysis. The original solid elements are replaced by ones with holes, the hole size being characterized by a so-called density (measure of the reduced volume). A homogenization method is used to find elastic moduli as a function of this density. Simpler approximations were developed to find plastic moduli and yield stress as functions of density.Optimality criteria were derived from an optimization statement using densities as the design variables. A resizing algorithm was constructed so that the optimality criteria are approximately satisfied. A novel feature is the introduction of an objective function based on strain energies weighted at specified times. Each different choice of weighting factors leads to a different structure, allowing a range of design possibilities to be explored.The method was applied to an automotive body rear rail. The original design and a new design of equal volume with holes were compared for energy absorption.

    Rapid shearing in a rate-type soil surrounding a cylindrical cavity (1984)
    New York, NY [u.a.] : Wiley-Blackwell
    International Journal for Numerical and Analytical Methods in Geomechanics 8 (1984), S. 141-155 
    Details
    ISSN: 0363-9061

    Thema: Architektur, Bauingenieurwesen, Vermessung , Geologie und Paläontologie
    Notizen: The stress and deformation resulting from rapidly applied axial traction on the face of a cylindrical cavity in a saturated soil are analysed. A simple rate-type constitutive model is used for the effective stress response.

    Rapid expansion of a cylindrical cavity in a rate-type soil (1984)
    New York, NY [u.a.] : Wiley-Blackwell
    International Journal for Numerical and Analytical Methods in Geomechanics 8 (1984), S. 125-140 
    Details
    ISSN: 0363-9061
    Schlagwort(e): Engineering ; Engineering General

    Thema: Architektur, Bauingenieurwesen, Vermessung , Geologie und Paläontologie
    Notizen: An analytical solution for rapid (undrained) expansion of a long cylindrical cavity from initially zero radius is presented. A simple rate-type soil model possessing the salient features of the modified Cambridge critical state model is used. Application of the solution to determination of the stress field surrounding a pile immediately after driving is discussed.
