    Notes:
    In this article we report the first detailed study of electrochemical capacitance-voltage profiling of ZnSe. An electrolyte consisting of 1 M sodium hydroxide and 1 M sodium sulphite has been developed that does not deposit selenium while etching the surface of n-type ZnSe during C-V profiling. The dissolution number of the electrolyte/ZnSe system is a function of the strength of electrolyte and the etching current and in order to obtain an accurate etching depth a constant etching current mode was used. A wide range of doping concentrations including both uniformly doped and staircase structures have been measured demonstrating that the electrochemical C-V profiler can now be a routine tool for assessing the growth parameters of ZnSe.

    Notes:
    We have directly measured the damping of wake-field deflection modes in a slow-wave accelerating structure consisting of a dielectric-lined waveguide with segmented conducting boundaries wrapped with rf absorbing material. Such damping of deflection modes is desired to prevent beam breakup instabilities. Attenuation e-folding times of 246 ps were recorded for deflection modes at the Advanced Accelerator Test Facility while the quality of the desired accelerating mode remained unaffected.

    Notes:
    The density of occupied interface states as a function of energy in nonohmic polycrystalline Bi-doped ZnO was obtained using photocapacitance measurements. Peaks in the interface states' densities were observed at depths of 2.46 and 2.79±0.08 eV from the bottom of the conduction band. The combination of these two states was found in photoconductance measurements on Bi-doped samples of ZnO and not found in undoped samples; thus, these states were assumed to be related to interface states that arise from doping with Bi.

    Notes:
    Plasma jets have been produced by the pulsed laser ablation of bulk ZnSe targets. Electrical measurements show that a sudden increase in ion yield occurs at a threshold pulse energy density of 210 mJ cm−2 pulse−1. The plasmas obtained do not exhibit overall electrical neutrality, but have a net positive charge, while the ZnSe target develops a corresponding negative charge. The initial ion translational kinetic energies are also found to be very low, 〈1 eV. These observations suggest that the ablation process is the result of a buildup of photogenerated holes at the semiconductor surface sufficient to result in disintegration of the lattice and rapid vaporization at low thermal energies.

    Objective To measure the plasma levels of corticotrophin-releasing hormone and corticotrophin-releasing hormone binding protein in normal pregnancy and in pregnancies complicated by pre-eclampsia.Setting John Radcliffe Hospital, Oxford and St Thomas's Hospital, London.Subjects One hundred and twenty pregnant women sampled prospectively throughout gestation, of whom 91 experienced a normal pregnancy and eight developed pre-eclampsia; in a second study, 10 women with severe pre-eclampsia, presenting at a range of gestational ages, were sampled once and compared with appropriately matched normal pregnant women.Main outcome measure Plasma levels of corticotrophin-releasing hormone determined by immunoradiometric assay. Plasma levels of corticotrophin-releasing hormone binding protein measured by direct radioimmunoassay.Results In the prospective study, plasma samples from women with pre-eclampsia exhibited higher (390.2 versus 292.7 pmol/l at 36 weeks) levels of corticotrophin-releasing hormone and significantly lower (5.24 versus 8.14 nmol/l at 36 weeks, P 0.002) levels of corticotrophin-releasing hormone binding protein than normal controls. In the second, single time point study a significant elevation in CRH (P 〈 0.002) and reduction in CRH-BP (P 〈 0.001) was found in pre-eclamptic pregnancies compared with controls.Conclusions In human pregnancies complicated by pre-eclampsia there is an elevated level of corticotrophin releasing hormone whilst there is less corticotrophin-releasing hormone binding protein; therefore there is a net increase in free potentially bioactive hormone which may play a role in the pathology of the disease.
