    Notes: Summary. In a prospective, randomized, cross-over study, 14 postmenopausal women completed 9 months of treatment with conjugated equine oestrogens, 1.25 mg daily. Seven women added dydrogesterone 20 mg daily for 12 days during months 2, 3 and 4, and then 10 mg daily for an identical time in months 5,6 and 7. The other seven women added the two dydrogesterone doses in reverse sequence. No dydrogesterone was taken during months 8 and 9. Lipids and lipoproteins were measured before treatment and at the end of months 4, 7 and 9. Lipids were also estimated in an untreated (reference) group of eight postmenopausal women on two occasions 6 months apart; these showed significant changes in HDL2- and HDL3-cholesterol. In the treatment group, HDL-cholesterol and apolipoprotein (apo) Al were significantly higher and LDL-cholesterol and apo B were significantly lower at months 4, 7 and 9 compared with baseline values. Triglyceride levels were increased significantly over baseline values, but remained within the normal range. No significant differences between the two dydrogesterone doses were observed on any lipid and lipoprotein fraction, nor were there any differences between the oestrogen-only and oestrogen/dydrogesterone treatment phases. Dydrogesterone appears to cause little, if any, lipid and lipoprotein changes and assessment in a larger population of postmenopausal women is warranted.

    Noncontacting microwave coupling to a cryogenic gravitational radiation antenna (1993)

    Notes: Gravitational radiation detectors must detect extremely small displacements, and thus require elaborate vibration isolation systems to attenuate the surrounding environmental noise. Contacting electrical leads can provide a direct path that will short circuit the vibration isolation, and degrade the antenna Q factor. Noncontacting microstrip transceivers provide a practical means of electromagnetically coupling to a resonant bar gravitational antenna when a microwave transducer is used as a signal readout system. Two microwave patch antennas now operate as transceivers on the University of Western Australia's 1.5 tonne niobium bar gravitational radiation antenna and are described in detail in this paper. This system allows improved vibration isolation without degradation of the acoustic Q factor of the niobium bar. Combined with a cryogenic amplifier, this system should achieve a reduction of 57 dB in the series noise power. This corresponds to a factor of 700 reduction in the effective displacement noise when referred to the transducer, from 2×10−16 to 3×10−19 m/(square root of)Hz.

    Notes: A modified version of the microwave signal processing system for the 1.5 tonne niobium bar gravitational radiation antenna at the University of Western Australia has been developed and tested during preparations for long-term observation. Among the new features of the system are a noncontacting microwave coupling to the motion transducer, cryogenic low-noise amplification, and automatic carrier suppression with improved long-term stability.

    Predicted, actual and optimal precompetition anxiety in adolescent track and field athletes (1992)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Anxiety was assessed in younger and older adolescent athletes in an attempt to test aspects of Hanin's zone of optimal function theory. Sixty-five participants in a track and field camp completed anxiety inventories at baseline and were instructed: 1) to recall how anxious they felt prior to their best performance and 2) to predict how anxious they would feel prior to an informal meet to be held 4 days later. Actual precompetition anxiety was assessed 1 h prior to the meet. Predicted precompetition anxiety was significantly higher than baseline and actual precompetition anxiety. Mean actual precompetition anxiety was not elevated above baseline. However, 34% (22/65) of the sample experienced high levels of precompetition anxiety, and the majority of these (17/22) reported performing optimally with high anxiety. Significant correlations between predicted and actual precompetition anxiety occurred for boys, but not for girls. The differences between predicted and actual precompetition values tended to be smaller in boys than in girls. Based on this sample, it is concluded that: 1) in accordance with the zone of optimal function theory, young athletes display considerable diversity in actual and optimal precompetition anxiety values; and 2) young athletes tend to overestimate the level of anxiety they will experience prior to an easy competition.

    Notes: Kinematic X-ray and electron scattering factors, found with the use of relativistic Hartree–Fock atomic fields, are tabulated for 76 atoms and ions. Parametric fits to these are given in the range of sin θ/λ from 0.0 to 2.0 Å−1. A method is developed to obtain the electron structure factor for forward scattering for a crystal containing ionized atoms.

    Reciprocity in electron diffraction and microscopy (1968)

    Notes: The Reciprocity Theorem of scattering theory is shown to hold generally for electrons scattered elastically in an absorbing medium, and also for inelastically scattered electrons, to a certain approximation. Two scattering symmetry conditions are defined by applying the theorem to crystals having mirror symmetry parallel to the crystal surface, and to centrosymmetric crystals. These are general forms of conditions demonstrated by Fukuhara (J. Phys. Soc. Japan (1966), 21, 2645). A number of symmetry effects observable in electron microscope images of crystals result from one or other of these conditions. The variation of intensity of diffracted beams as a function of angular deviation from the Bragg condition is considered in detail. The symmetry of bright-field images of defects lying at equal distances from the crystal surfaces was first explained by Howie & Whelan (Proc. Roy. Soc. (1961), A 263, 217); such symmetry properties can be conveniently classified and explained by the reciprocity theorem. A method of obtaining high-resolution dark-field images, due to Cowley, is based on the use of the reciprocity theorem. Examples of its application for both Bragg and diffusely scattered electrons are given.

    The effects of n-beam dynamical diffraction on electron diffraction intensities from polycrystalline materials (1969)

    Notes: Calculations based on n-beam dynamical diffraction theory have shown that the intensities of rings and arcs in diffraction patterns from polycrystalline materials are strongly dependent on the experimental conditions. For arc patterns from BiOCl, calculations confirm a revised formula for the intensities from very thin crystals and indicate dependences on the distributions of orientation, thickness and bending of the crystals which are sufficient to account for the wide deviations of recent experimental results from the predictions of the primary extinction formula, based on the two-beam approximation. Inferences regarding the possible errors in electron diffraction analysis of crystal structures, especially for materials containing heavy atoms, are drawn from calculations relating to the intensities of arc patterns from AgTISe2. It is suggested that n-beam calculations should be made in order to avoid serious error in the refinement stages of a structure analysis.
