    Description / Table of Contents: Résumé Les auteurs ont étudié les résultats de deux groupes comparables de patients porteurs d'une discopathie lombaire dégénérative certaine, opérés les uns par laminectomie complète, les autres par simple fenestration. Deux facteurs conditionnent le pronostic postopératoire en ce qui concerne la lombalgie: la durée de l'intervalle séparant le début des symptômes de l'opération, après une période de traitement médical, et la présence d'une hypermobilité au niveau opéré. La voie d'abord ne modifie en rien le résultat de l'ablation de la hernie discale.
    Notes: Summary The results from two matched operative groups with proven lumbar disc degeneration, who underwent full laminectomy or true fenestration have been compared. Two factors determine post operative prognosis in terms of back ache; the length of time between onset of symptoms and operation after a period of conservative care, and the presence of hypermobility at the operative level. The method of exposure of the affected level has no effect on the outcome of the removal of prolapsed disc material.

    Notes: Abstract A number of published studies have investigated the application of neural network technology to residential property appraisal. The majority of these studies have concentrated on homogeneous areas (that is areas where properties are subject to the same environment and locational factors). This is generally done to restrict the data set to one local sub- market. However, the models created are specialised and not locationally portable. This paper presents a methodology, which builds on research reported by James [1], in which a Kohonen map is used to uncover sub-markets within a large data set that are subsequently independently used to train a series of back-propagation networks. (The paper also introduces a novel boundary detection algorithm for a Kohonen self organising map.) The study concludes that by modelling possible sub-markets an acceptable accuracy over a heterogeneous area can be achieved. The work presented in this paper is funded via a Realising Our Potential Award under the auspices of the ESRC.

    Notes: Abstract A new in vitro test suitable for the large scale screening of chemical compounds for anthelmintic activity is described. The test which utilizes the fourth larval and adult stages ofNippostrongylus brasiliensis in a medium capable of supporting the growth and development of the parasite, detects selectively those compounds which possess either broad spectrum anthelmintic or specific anti-trichostrongyle activity. The screen is easy to operate requiring only minute quantities of experimental compound. It renders fully reproducible results which furthermore can be interpreted objectively. This is the first reported in vitro test directed against the parasitic stages of a nematode that is capable of detecting reliably the activity of a wide range of anthelmintics including thiophanate and all the benzimidazoles.
