    Notes: [Auszug] To help decide between these three hypotheses we have treated eggs of the milkweed bug, Oncopeltus fasciatus, with a juvenile hormone analogue and exchanged larval integument between individuals in the treated and untreated groups. The results demonstrate that there is enough hormone in the treated ...

    Notes: [Auszug] It has often been, suggested that molecules conveying the information necessary for defining the spatial pattern of differentiation may pass from cell to cell via low electrical resistance pathways7-9. There is little evidence to support these ideas, although Dixon and Cronly-Dillon10 have reported ...

    The cold compaction of several mineral powders (1973)
    Springer
    Journal of materials science 8 (1973), S. 770-776 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Four mineral powders with widely different mechanical properties have been studied in prolonged cold compaction. An analysis of the time-dependent deformation has been attempted by splitting the finite strain into two components, one a linear function of time. A single compaction equation has been developed and applied to all four powders. The empirical constants of this equation have been examined, proposals concerning the mechanism of compaction under the prolonged application of pressure have been advanced and a correlation between the empirical parameters and the mechanical constants of the materials has been attempted. Suggestions for future work have been made.

    Notes: Abstract Four mineral powders with widely different mechanical properties have been studied in cold compaction. The effect of final compacting pressure and particle size have been investigated. An analysis of the experimental data indicates that the same basic empirical compaction equation can be applied to the compaction of all four powders. A theoretical model for the compaction process is developed and the empirical parameters are correlated with the mechanical constants of the materials.

    Some theoretical considerations of fibre pull-out from an elastic matrix (1972)
    Springer
    Journal of materials science 7 (1972), S. 1-6 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Previous theoretical work on fibre pull-out from an elastic matrix is briefly discussed and its relation to this present work is indicated. The form of the distribution of shear stress and that of load along the fibre length is determined and its dependence on the elastic properties and fibre length is shown. The theory has been developed to account for the debonding of fibres from the matrix. The maximum fibre load necessary to cause complete debonding and subsequent pull-out is determined and the dependence of the maximum shear stress on the effective embedded fibre length is shown to affect the shear strength calculated from a pull-out test.
