ISSN: 1365-2044Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The anaesthetic management of a young woman with dystrophia myotonica is described. The use of atracurium and monitoring of neuromuscular block allowed suxamethonium and neostigmine to be avoided, and thereby to reduce the risk of myotonic contractions. No adverse sequelae were observed.Type of Medium: Electronic ResourceURL: -

Published 1991Staff ViewISSN: 1434-6052Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract Data on multiplicities of charged particles produced in proton-nucleus and nucleus-nucleus collisions at 200 GeV per nucleon are presented. It is shown that the mean multiplicity of negative particles is proportional to the mean number of nucleons participating in the collision both for nucleus-nucleus and proton-nucleus collisions. The apparent consistency of pion multiplicity data with the assumption of an incoherent superposition of nucleon-nucleon collisions is critically discussed.Type of Medium: Electronic ResourceURL: -

Fritiof and Venus models mostly describe the dependence of second moments on rapidity intervals in minimum bias interactions, but not in central collisions. For central collisions the behaviour of second moments might indicate enhanced multiplicity fluctuations.Type of Medium: Electronic ResourceURL: -

Published 1991Staff ViewISSN: 1434-6052Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract We report on a systematic study of midrapidity transverse energy production and forward energy flow in interactions of16O and32S projectiles with S, Cu, Ag and Au targets at 60 and 200 GeV/nucleon. The variation of the shape of theE T distributions with target and projectile mass can be understood from collision geometry. AverageE T values determined for central collisions show an increasing stopping power for heavier target nuclei. A higher relative stopping is observed at 60 GeV/nucleon than at 200 GeV/nucleon. Bjorken estimates of the energy density reach approximately 3 GeV/fm3 in highE T events at 200 GeV/nucleon with16O and32S projectiles. The systematics of the data and the shapes ofE T and pseudorapidity distributions are well described by the Lund model Fritiof.Type of Medium: Electronic ResourceURL: -

Even though the age of cultures and all the environmental conditions were identical, only one of them expressed a clear morphogenic potential, and the differences are expressive in the isozyme banding patterns observed for creatine phosphokinase, lactate dehydrogenase and indoleacetaldehyde dehydrogenase. No differences in alkaline phosphatase isozymes were detected.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-9842Source: Springer Online Journal Archives 1860-2000Topics: ArchaeologyDescription / Table of Contents: Résumé La découverte des usages du feu et ensuite de sa préparation est fondamentale pour l'humanité. Suite à des rapports au cours de la dernière décennie signalant des traces de feu relevées dans des sites archéologiques du Pléistocène inférieur dans l'est de l'Afrique, la datation du contrôle du feu par les hominiens est devenu une source de controverse. Dans cet article, nous révisons d'un oeil critique les contextes et la nature des cas de feu signalés à Koobi Fora et à Chesowanja au Kenya, et à Gadeb et dans l'Awash moyen en Éthiopie, à la lumière d'une suite de techniques archéometriques. Suit en conclusion une discussion sur les rôles qu'aurait pu jouer le feu dans les modes de vie des hominiens vivant dans les savannes du Pléistocène inférieur.Notes: Abstract Discovery of the uses and later the invention of fire-making are fundamental to humanity. Following reports over the last decade of traces of fire found on Lower Pleistocene archaeological sites in eastern Africa, the dating of the control of fire by hominids has become a controversial issue. In this paper we critically review the contexts and, in the light of a battery of archaeometric techniques, the nature of reported instances of fire from Koobi Fora and Chesowanja in Kenya, and from Gadeb and the Middle Awash in Ethiopia. We conclude with a discussion of the roles fire may have played in the lifeways of early Pleistocene savanna-living hominids.Type of Medium: Electronic ResourceURL: -
