    Notes: [Auszug] IN my research-student days, a colleague with literary ambitions threw his draft thesis on nuclear physics out of the window and settled down to write real fiction instead, although without much success. Fred Hoyle, in contrast, has succeeded in producing outstanding work in both astrophysics and ...

    Notes: Summary Measurements done on electron micrographs show that in myofibres with sarcomeres contracted to below 2.1 μm, proportional shortening of the A bands occurs. In muscles from patients with idiopathic scoliosis very short A bands are especially prominent.

    Description / Table of Contents: Abstract Wegener's expeditions pioneered many measurements that are now essential for computer modelling of ice sheets. Advances in knowledge of accumulation, thickness, temperature, crystal fabric and surface mapping of ice sheets and of impurities, gas content and isotopic ratios of ice cores from these ice sheets are outlined before computer modelling work is discussed. The value of such studies in providing large scale tests of geophysical concepts is emphasized. The paper concludes by suggesting that the drag of continental ice sheets on the top of continental blocks might be of comparable magnitude and tend to balance forces on the base of these blocks by motion of the asthenosphere. Apart from providing a possible reason for the aseismic nature of the Antarctic and Greenland land masses, the hypothesis provides a suitable link for this volume between Wegener's interest in continental ice sheets and continental drift.
    Abstract: Résumé Les expéditions de Wegener ont suscité de nombreuses mesures qui ont fourni des données aujourd'hui mûres pour établir des modèles de couvertures glaciaires par la voie de calculatrices. Mais avant de discuter ce procédé, mention est faite des progrès accomplis dans la connaissance de l'accumulation, de l'épaisseur, de la température, de la structure cristalline et de la cartographie des couvertures glaciaires ainsi que de leurs impuretés, leur teneur en gas et les rapports d'isotopes dans les carottes qui y ont été prélevées, études dont il convient de souligner la valeur par les données à grande échelles qu'elles ont fourni à l'appui de concepts géophysiques. Le mémoire conclut sur la suggestion que les forces d'entrainement des couvertures glaciaires continentales sur la surface des blocs continentaux doit être d'un ordre comparable aux forces agissant à la base de ces blocs dans leur mouvement sur l'asthénosphère et qu'ils tendent à égaler. Outre qu'elle donne une raison possible de la nature asismique du continent antactique et du Groenland, cette hypothèse, dans ce volume, forme un trait d'union dans les intérêts que Wegener a portés aux couvertures glaciaires continentales et à la dérive des continents.
    Notes: Zusammenfassung Wegeners Expeditionen haben viele Messungen angeregt, die zu Ergebnissen geführt haben, die nunmehr reif sind für Computer-Modelle von Eisdecken. Es werden die Fortschritte in der Kenntnis von Akkumulationsraten, Mächtigkeit, Temperatur, Kristallstruktur, Oberflächenkartierung von Eisdecken und Verunreinigungen umrissen. Danach wird die Arbeit mit dem Computer-Modell diskutiert. Der Wert solcher Untersuchungen für großmaßstäbliche Tests geophysikalischer Konzepte wird betont. Die Ergebnisse lassen erwarten, daß die Schubkräfte der kontinentalen Eisdecken auf dem Top der kontinentalen Blöcke in derselben Größenordnung liegen könnten wie die aus der Bewegung der Asthenosphäre an der Basis dieser Blöcke. Letztere könnten damit kompensiert werden. Unabhängig davon, daß die aufgestellte Hypothese mögliche Argumente für die aseismische Natur der Antarktischen und Grönland-Massen aufzeigt, verbindet sie im Rahmen dieses Bandes Wegeners Interesse an kontinentalen Eisdecken mit der Kontinentaldrift.

    Notes: [Auszug] Seismic, radio-echo, TWERLE balloon and oceanographic data of the Filchner-Ronne ice shelves are analysed. A large thin area in the central Ronne Ice Shelf is found to differ from the morphology of the Ross and Filchner ice shelves. This area is partly filled by basal saline ice, which can be ...

    Notes: [Auszug] Arctic and Antarctic was a title used previously in 1939 by Colin Bertram with the subtitle The Technique of Polar Travel. In that book, published by Cambridge University Press, Bertram discussed basic principles of travel in an age when dog teams had not given way entirely to tractors and ...

    Notes: Abstract A stainless steel, Klovan-type box corer for use by SCUBA divers in shallow water has been developed. Details for construction of the 0.45 × 0.30 × 0.20-m wedge-shaped corer are provided together with operational details. Excellent undisturbed samples have been collected from gravelly sands, sands, and muds at water depths ranging from 15 m to intertidal. The wet sand cores typically are treated in the field using an epoxy to obtain high-relief sediment peels.

    Description / Table of Contents: Résumé L'observation des malades atteints de cancer colorectal constitue une base significative pour l'étude du traitement des tumeurs solides. Un programme qui rassemble les différentes disciplines thérapeutiques ne peut être que profitable. Il permet de dépister et de prévenir toute affection associée secondaire, de déceler un processus tumoral nouveau mais indépendant du premier d'établir une action thérapeutique spécifique pour les catégories à haut risque. Les données déjà obtenues à partir de ces tentatives de traitement pluridisciplinaire ne peuvent être que bénéfiques pour tous les malades.
    Notes: Abstract The follow-up of patients with colorectal cancer is a representative model for the management of solid tumors. A program that integrates multidisciplinary care serves the best interests of patients in the areas of identification and management of recurrence, identification and prevention of metachronous disease, detection of independent new primary cancers, and establishment of programs for particular high-risk categories. Data evolving from such organized follow-up efforts will benefit the management of all patients.
