    Notes: [Auszug] AN article in NATURE for August 18 deals aptly with the question of testing for colour-vision. It is to be hoped that the committee at present inquiring into the matter will advocate that testing should be carried out in future in conditions resembling as nearly as possible those on which ...

    Plant gene expression in effective and ineffective root nodules of alfalfa (Medicago sativa) (1987)

    Notes: Abstract Expression of plant genes involved in the symbiosis between alfalfa (Medicago sativa) and Rhizobium meliloti has been studied by comparing root and root nodule mRNA populations. Two-dimensional gel electrophoretic separation of the in vitro translation products of polyA+ RNA isolated from either roots or effective root nodules has allowed us to identify thirteen nodule-specific translation products, including those corresponding to the leghemoglobins (Lb). These translation products, representing putative nodulin mRNAs, are first detected between 9 and 12 days after inoculation, a result which has been confirmed for Lb mRNA by Northern blotting and hybridization with a Lb cDNA probe. Analysis of three different types of ineffective root nodules arrested in different stages of development has led to the following conclusions. (i) The transcription of eleven nodule-specific genes, including the Lb genes, is independent of nitrogen-fixing activity. (ii) Differentiation of the primary nodule structure does not require the transcription of any of these genes but can be correlated with a dramatic reduction in the level of at least five transcripts present in the root. (iii) There is enhanced expression of certain plant genes in the case of nodules elicited by an Agrobacterium strain carrying the symbiotic plasmid of R. meliloti.

    Analysis of dynamic mixed-mode isochromatics (1985)
    Springer
    Experimental mechanics 25 (1985), S. 344-353

    Notes: Abstract The mixed-mode, elastodynamic state of stress in the neighborhood of a constant-velocity crack tip is used to generate numerically unsymmetric isochromatics. Unsymmetry associated with the third-order terms of a mixed-mode stress field, with and without the Mode II singular stress term, is also investigated. In extractingK I from an unsymmetric isochromatic pattern, errors in the Mode I fracture parameters due to the assumed presence ofK II in aK I stress field were found to be significant when data are taken more than 4 mm from the crack tip.

    DeterminingK and related stress-field parameters from displacement fields (1985)
    Springer
    Experimental mechanics 25 (1985), S. 399-407 
    Details
    ISSN: 1741-2765
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract A general algorithm is presented that computes the stress-field parameters for opening-mode crack problems in a least-squares sense from full-field moiré or speckle-displacement fringe patterns. The algorithm can be used in the presence of rigid-body rotation and does not require absolute fringe numbering. Extensive numerical experiments were conducted with the algorithm to determine the sensitivity of the method to experimental errors. Small random position errors in locating the fringe maxima were found to have a negligible influence on the stress-intensity-factor calculation when the number of data points was about ten times greater than the number of unknown stress-field parameters. It was also found that systematic position errors due to an incorrectly specified crack-tip location could be minimized by assuming various crack-tip locations in the vicinity of the actual crack tip and selecting the best fit results. Bothu andv fields were found to be equally suitable for determination of the stress-intensity factor.
