    A determination of the absolute values and signs of the 111 and 222 structure factors of silicon (1974)

    Notes: The thickness fringes of a silicon wedge at the Bragg positions for 111 and 222, and at the symmetric position for hhh were observed with the electron microscope at 100 and 392 kV. The ratios of the measured fringe distances were analysed by the many-beam dynamical theory in electron diffraction assuming the theoretical values for the structure factors of orders higher than 333. As the result, the crystal structure factors are derived as F111 = 59.87 ± 0.46 and F222 = - 1.85 ± 0.85 at 293 °K.

    EFFECTS OF NOISE ON HUMAN PLACENTAL LACTOGEN (HPL) LEVELS IN MATERNAL PLASMA (1977)

    Notes: The levels of human placental lactogen (HPL) in the serum of expectant mothers both subjected to and not subjected to aircraft noise were measured. The HPL levels in the quiet reference area and in the noise area were similar before the 29th week of pregnancy. However, the HPL levels of subjects in the noise area tended to be lower than those in the reference area after the 30th week of pregnancy and the difference became significant after the 36th week of pregnancy. The lower HPL levels were associated with lower birth weight for infants of mothers who lived in the noise area.

    X-ray diffraction phenomena in elastically distorted crystals (1970)
    Copenhagen : International Union of Crystallography (IUCr)
    Applied crystallography online 3 (1970), S. 74-89 
    Details
    ISSN: 1600-5767

    Topics: Geosciences , Physics
    Notes: Diffraction phenomena in diametrically compressed single-crystal plates of silicon were systematically studied by topographic methods of the traverse and section types with Cu, Mo and Ag radiations. Black and white contrasts in the traverse topographs depend on the magnitude of the strain gradient, absorption, the sign and the order of the reflection vector, and the crystallographic orientations of the specimens. The results were interpreted in terms of the diffraction theory for a constant strain gradient. The distribution of the strain gradient was calculated under the assumptions of plane stress and isotropic elastic constants. Qualitative agreement was obtained between the theory and experiments. The behaviour of the contrast, including the departure from Friedel's law, is due to Borrmann absorption in distorted crystals. The quantitative discrepancy is explained by anisotropy of the elastic constants. The departure from a constant strain gradient is detectable by the asymmetry of the intensity distribution in section topographs.

    An anomalous beam observed in X-ray diffraction topographs (1970)
    Copenhagen : International Union of Crystallography (IUCr)

    Notes: In X-ray diffraction topographs for nearly perfect crystals including a local heavy distortion, an anomalous beam was sometimes observed outside the ordinary section topograph. Experimentally, it was confirmed that the beam is due to the Bragg reflection of Kα2 and continuous components included in the incident radiations.

    Notes: Based on the Lagrange multiplier's concept, a superposition method of analytical and finite element solutions has been developed to solve efficiently various non-linear and/or time-dependent problems in structural mechanics. According to the theory, the transient creep behaviour of a cantilever beam is analysed as an expository example.
