    A numerical model of fine sediment transport on the continental shelf (1982)

    Notizen: Abstract A numerical model of fine-grained sediment dispersion in the New York Bight of the North American continental shelf is presented. Large amounts of waste material have been dumped in this region and the dispersal patterns of this material are of great interest to environmental managers. The model assumes that fine sediment resuspension is determined by surface wave activity and that transport is determined by tidal currents. Considering surface wave activity to be a random process reduces sediment motion to a random walk which is governed by a diffusion equation. The diffusion equation is solved numerically by an implicit time difference, finite element algorithm for a number of initial conditions. Initial conditions corresponding to ocean dumping sites show patterns of dispersal controlled by the geometry of the study region and the anisotropy of the tides. Material dumped at currently used dump sites reaches sensitive coastal areas before it leaves the continental shelf. Examination of the diffusion coefficients suggests an alternative dump site for fine-grained material. This dump site is relatively near sources of dumped material but produces minimal impact on coastal areas. This site should be considered as a possible alternative to expensive direct disposal at deep ocean sites.

    Combined Administration of a 5-Hydroxytryptamine (5-HT)1D Antagonist and a 5-HT Reuptake Inhibitor Synergistically Increases 5-HT Release in Guinea Pig Hypothalamus In Vivo (1996)
    Oxford, UK : Blackwell Science Ltd

    Notizen: Abstract: In vivo microdialysis in guinea pig hypothalamus was used to study the effect of serotonin [5-hydroxytryptamine (5-HT)] subtype 1D autoreceptor blockade on the increase in extracellular 5-HT levels produced by a selective 5-HT reuptake inhibitor (SSRI). Administration of the selective 5-HT1D antagonist GR127935 at 0.3 mg/kg had no effect, but 5 mg/kg significantly increased extracellular levels of 5-HT and 5-hydroxyindoleacetic acid to 135% of basal values. Moreover, at these doses GR127935 significantly attenuated the decrease in extracellular 5-HT levels following local perfusion with the selective 5-HT1D agonist CP-135,807. The SSRI sertraline at 2 mg/kg increased 5-HT levels to 130% of basal levels. The combination of this low dose of sertraline with either dose of GR127935 resulted in a pronounced, long-lasting increase in 5-HT levels to 230% of basal values. These results indicate that the effects of an SSRI on terminal 5-HT are significantly enhanced by coadministration of a 5-HT1D antagonist and confirm that in addition to somatodendritic 5-HT1A autoreceptors, terminal 5-HT1D autoreceptors mitigate the effect of SSRIs on terminal 5-HT. As such, antagonists of the 5-HT1D autoreceptor could be useful as rapidly acting antidepressants and may shorten the onset of antidepressant action when combined with SSRIs.

    Notizen: “There was something a little unseemly about how the building societies intending to demutualise did so by encouraging their members to vote in favour with the inducement of significant payments in shares”. Should one have no regard for the intentions of those who produced the present capital accumulation, or for the idea of holding reserves in trust for future members? The author is DBM Professor of Corporate Governance at Leeds Business School, Leeds Metropolitan University, Calverley Street, Leeds LS1 3HE.

    Notizen: Examines the role of non-executive directors. Argues that there is universal agreement on the need for outsiders to be involved in company direction and that shareholders are not able to provide the necessary checks and balances to supervise board activities. Examines research on the system of non-executive directors. Argues that there is a need to develop procedures to select non-executives that are rigorous and add value. Concludes that non-executive directors will have increasing influence on company direction.
