    Transport and the Environment: Effects of Organic Pollutants on Water Quality (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 11 (1997), S. 0

    Notes: The eighteenth report of the Royal Commission on Environmental Pollution made no reference to any potential environmental impacts resulting from runoff pollution associated with transport activities. This paper identifies the magnitude and extent of pollution associated with discharges from various transport sources and identifies solids, metals, hydrocarbons, herbicides and de-icing agents as the principal contaminants of environmental concern. The impacts of these pollutants on the receiving water are reviewed. They are primarily associated with highways which have a high traffic density, and herbicides are considered to be the only potential and widespread hazard to groundwaters. Highway and airport runoff are shown to have both acute and chronic effects on biotic diversity and organism mortality rates, although these effects appear to be largely confined to reaches immediately downstream from the discharge outfalls.

    Helium atom scattering study of the frustrated translation mode of CO adsorbed on the Cu(001) surface (1995)

    Notes: The structure and vibrational modes of CO adsorbed on Cu(001) have been investigated by helium atom scattering (HAS). Below coverages of θ=0.13, CO adsorbs as isolated molecules, and the time of flight (TOF) spectra of helium atoms scattered from the surface are characterized by energy losses and gains of 3.94 ± 0.07 meV. With the aid of isotope shift measurements, this mode is unambiguously assigned to the frustrated translation mode of the adsorbed CO. In the c(2×2) structure (θ=0.5) this mode is found to show dispersion in both the 〈100〉 and 〈110〉 azimuths with frequencies ranging from 3.9 meV at the zone origin to 5.6 meV at the zone boundary. A simple force constant model with a single nearest neighbor force constant within the layer is found to be sufficient to describe the dispersion. For coverages slightly less than θ=0.5 the angular distributions of scattered helium atoms show features characteristic of vacancies in the overlayer. In the TOF spectra an additional nondispersive mode at about 4 meV is also seen and assigned to the frustrated translation of CO molecules adjacent to the vacancies in the c(2×2) overlayer. The Rayleigh mode is clearly observed in the c(2×2) structure but is found to decrease slightly in frequency while the longitudinal resonance, which is especially prominent on the clean surface, disappears completely. The results are interpreted with the aid of slab calculations. © 1995 American Institute of Physics.

    Ontogenic changes and sexual dimorphism in the head, mouth and teeth of the lesser spotted dogfish (1995)

    Notes: Male Scyliorhinus canicula possess a longer and narrower mouth than females resulting in pronouced sexual dimorphism with respect to the mouth length/mouth width ratio (0.49 and 0.43, respectively). Significant sexual differences in the girth of the head and pre-oral, pre-branchial and head lengths were also recorded. Males were found to have longer teeth than females. Reasons for these differences are discussed.

    The reproductive biology of Scyliorhinus canicula in the Bristol Channel, U.K. (1997)
    Oxford, UK : Blackwell Publishing Ltd

    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Among 972 Scyliorhinus canicula, the overall sex ratio (males:females) was 1:1·23. Males matured between 490 and 540 mm LT with 50% maturity at 520 mm. Females matured between 520 and 640 mm LT with 50% maturity at 550 mm. Female gonadosomatic index peaked in May. Fecundity increased with fish length. The egg laying season lasted 10 months with a peak in June and July. The importance of erect, sessile invertebrates such as bryozoans, poriferans and hydroids as egg-case deposition sites has been established. Recently hatched fish were born in an equal sex ratio and at a mean length of 100·5 mm and mean weight of 3·07 g. One intersexual fish is described.

    Genetic and antigenic variation in the haemagglutinin of recently circulating human influenza A (H3N2) viruses in the United Kingdom (1995)
    Springer

    Notes: Summary Variation in the haemagglutinin (HA) gene of influenza A (H3N2) viruses isolated in the U. K. and abroad from 1992–1994, was determined by nucleotide sequencing of the HA1 domain of the HA gene. Viruses isolated in the U.K. early in the 1992–93 season were from the A/Beijing/353/89 lineage and were replaced later that season by viruses from the A/Beijing/32/92 lineage. Viruses from the new lineage continued to be isolated during the 1993–94 season, but were heterogeneous. Most of these isolates were more closely related to an A/Beijing/32/92 variant, A Hong Kong/23/92, but could be distinguished into three groups by serology (of which one group was circulating during the previous season) and four groups based on sequence variation in the HA gene. However, phylogenetic analysis of antigenically-distinct isolates showed that the HA gene is evolving along one lineage. Sequence analysis identified mainstream, subgroup and strain specific amino acid substitutions. There was a broad correlation between the observed amino acid changes and the antigenic sites of the HA. The results of this study highlight the value of regular molecular analysis of circulating viruses.

    Nifedipine pharmacological variables as risk factors for gingival overgrowth in organ-transplant patients (1997)

    Notes: Abstract The prevalence and severity of gingival overgrowth in organ-transplant patients medicated with cyclosporin are greater in patients concomitantly medicated with nifedipine; however, no relationship between the gingival overgrowth and any of the nifedipine pharmacological variables has been demonstrated. The study examined the effect of five nifedipine pharmacological variables (nifedipine dosage, plasma concentration and gingival crevicular fluid concentration, M1 metabolite plasma concentration and the nifedipine:M1 ratio). The effect of the nifedipine variables on the gingival overgrowth score were examined using univariate and multivariate regression analysis. Adjustment for the effect of other risk factors was made by adding the distribution of each of the nifedipine variables in turn to a stepwise regression model containing previously identified risk factors for this condition. Despite the high levels of nifedipine sequestered in the GCF, only the plasma concentration of nifedipine was identified as a risk factor for the severity of gingival overgrowth in these patients (P = 0.01) once adjusted for other known risk factors (r 2 for the model = 55%).
