    Towards a unified description of the AMOB2O5 (A = K, Rb, Cs, Tl; M = Nb, Ta) family of compounds (2000)

    Notes: Single-crystal X-ray diffraction data (Mo Kα radiation) are used to re-refine the structure of RbNbOB2O5, rubidium niobium oxo pyroborate. The structure is refined as an incommensurate modulated structure with superspace group symmetry Pmn21(0,0.4,0)s and lattice parameters a = 7.406 (2), b = 3.939 (2) and c = 9.475 (2) Å. Refinement on 3242 unique reflections converged to R = 0.031, while a previous conventional superstructure refinement led to R = 0.090. This lowering of the R factor goes hand-in-hand with a substantial reduction in the number of refined parameters. The refinement strongly suggests that the structure is effectively incommensurately modulated, despite an apparently rational magnitude of the primary modulation wavevector and overlap of satellite reflections.

    Gel permeation chromatography: On the shape of the calibration plot and molecular size separability (1967)
    New York : Wiley-Blackwell

    Notes: Data obtained from the calibration of GPC columns of different permeabilities with standard polystyrenes are reported. For single columns the logarithm molecular weight-elution volume plot is linear for approximately one and one-half decades in molecular weight. GPC separations are such that the separability of two samples of similar molecular weight improves as their mean molecular weight decreases. Because of this the analysis of high molecular weight polymers can best be accomplished on a series of columns in which each column has a high permeability limit. The elution volume for columns in series is shown to be the sum of the elution volumes of the individual columns. As higher molecular weights are eluted a pronounced tailing effect is observed.

    Rib development in chick embryos analyzed by means of tantalum foil blocks (1969)
    New York, NY [u.a.] : Wiley-Blackwell
    American Journal of Anatomy 126 (1969), S. 127-149

    Notes: Rib development in chick embryos, with special emphasis on the origin of ribforming cells, has been analyzed by inserting tantalum foil blocks parallel to certain somites of the prospective rib-forming level. Intact edges of bent pieces of foil the width of 4-6 somites were inserted through the somatopleure at stage 14-16 either (1) immediately lateral to the nephrotome, (2) between proximal and distal portions of the lateral plate or (3) within the distal lateral plate. Edges of similar pieces of foil containing a triangular notch the width of 2 somites were likewise inserted through the somatopleure of stage 14-16 embryos (4) immediately lateral to the nephrotome or (5) between proximal and distal portions of the lateral plate.On the basis of the modified rib pattersn studied in toto after 11 days of incubation it was concluded that the (1) original somatic mesoderm does not participate in formation of vertebral rib components, (2) original somatic mesoderm plays some role in formation of sternal rib components (ribs 3-7) but probably does not contribute chondroblasts for this purpose, and (3) distalmost somatic mesoderm is not involved in rib formation. Consistent types of modified wings are described and also modifications of the body wall, breast and ventral feather tracts of the right side.
