    Notes: Summary. A multicentre trial was conducted to compare the efficacy and side-effects of an intramuscularly administered PGE2 analogue and vacuum aspiration in women with a delay of up to 21 days in the expected onset of menses. A total of 473 such women were randomly allocated to treatment with either 16-phenoxy-W-17, 18, 19, 20-tetranor PGE2 methyl sulfonylamide (three intramuscular injections of 0.5 mg at 3-h intervals) or vacuum aspiration, and the outcome of therapy assessed 1, 2 and 6–8 weeks later. Retrospective analysis of hCG levels indicated that 419 (88.6%) women had been pregnant at the time of treatment. With few exceptions, administration of the PGE2 analogue induced vaginal bleeding in both pregnant and non-pregnant women but the duration and subjectively perceived amount of bleeding were greater than after vacuum aspiration. Both treatments were equally effective. In pregnant women the overall frequency of complete abortion was 91% for prostaglandin treatment and 94% for vacuum aspiration. If non-pregnant women were included, the respective success rates (i.e. percentages of women not pregnant 2 weeks after treatment) were 92% and 95%. Gastrointestinal side-effects and lower abdominal pain requiring intramuscular analgesia were more common after prostaglandin therapy than following vacuum aspiration in both pregnant and non-pregnant women.

    Electrical and optical properties of Li-doped LiBO2 and LiNbO3 films (1994)

    Notes: Li-doped LiBO2 and LiNbO3 thin films have been studied and their optical and electrical properties determined. With doping the ionic conductivity of the films was found to increase substantially. The highest conductivity obtained with the doped films was about 4.5×10−6 S cm−1. All the films exhibited a high degree of transmission in the spectral region from 350 to 2500 nm. The remarkable increase in the ionic conductivity coupled to the preservation of a high optical transmission makes this doping technique highly attractive for devising ion conductors that can be used in transmissive solid-state electrochromic systems or the so-called "smart windows.''

    Electrical and optical properties of thermally evaporated LiBO2–LiF composite films (1995)

    Notes: Optical and electrical properties of the LiBO2–LiF composite thin films prepared by thermal evaporation have been studied for their use as ion conductors in solid-state electrochromic (EC) systems. All the LiBO2–LiF films exhibited a high degree of optical transmission (over 90%) and the best lithium ion conductivity attainable was about 8×10−7 S cm−1, a value considerably higher than that for the ionic conductivity of LiBO2. A typical activation energy of 0.545 eV was found for the composite film. The films obtained thus have a good potential for use as ion conductors in EC devices. © 1995 American Institute of Physics.

    Approaches to 1H-Cyclopropa[l]phenanthrenes. Eliminations with 1a,9b-Dihydro-1H-cyclopropa[l]phenanthrene Derivatives (1986)

    Notes: Base-induced elimination of the sulfonium salt 2i in the presence of furan affords the addition products 7 and 8, derived from 1H-cyclopropa[l]phenanthrene (1) and the isomeric cyclopropene 5a (Scheme 3). Upon oxidation, the selenide 2c yields phenanthrene-9-methanol (9), presumably via 1. No evidence for the intermediate 1 is obtained from sulfoxide pyrolysis with 2e, which leads to products formed by radical pathways (Scheme 5). Reductive elimination of the disulfone 3b gives half-reduction to monosulfone 2g and complete reduction to cyclopropane 2 as well as 9-methylphenanthrene (15), but no evidence for the intermediate 1.
