It can be argued that nonselective cation channels were the first sort of ion channel to be described, though the word channel was not used at the time. Their existence was implied by Fatt and Katz in 1952, when they described the action of acetylcholine at the muscle endplate as producing "a large nonselective increase of ion permeability, i.e. a short circuit". Shortly afterwards, in 1956, Katz referred to "aqueous channels through which sma...

. . . John Harper . . . Nature conservation has changed from an idealistic philosophy to a serious technology. Ecology, the science that underpins the technol­ ogy of conservation, is still too immature to provide all the wisdom that it must. It is arguable that the desire to conserve nature will in itself force the discipline of ecology to identify fundamental prob­ lems in its scientific goals and methods. In return, ecologists may be able t...

The study of quantum fluids in three dimensions has been an important area for many years as it embraces Bose-Einstein condensation, superfluidity and macroscopic quantisation. These are fundamental aspects of physics which can be studied in liquid 4He. In contrast, quantum fluids in two dimension is more recent and less developed. Nevertheless it has shown many interesting phenomena including a rich variety of phases and the Kosterlitz-Thoule...

The Burg Wartenstein Symposia have become rightly celebrated for achieving their original purpose: to be of service and interest to the anthropological profes­ sion as a whole and to contribute to related sciences. We are specially grateful to the Board of Directors of the Wenner-Gren Foundation for Anthropological Research for the award of a symposium on Physical Anthropology and Nutritional Status. We had considered that such a subject was t...

A NATO Advanced Study Institute (ASI) on High-Brightness Accelerators was held at the Atholl Palace Hotel, Pitlochry, Perthshire, Scotland, from July 13 through July 25, 1986. This publication is the Proceedings of the Institute. This ASI emphasized the basic physics and engineering of the rela­ tively new and fast-emerging field of high-brightness particle accelera­ tors. These machines are high- to very-high-current (amperes to hundreds of k...

Now in its second edition, Seeing the Bigger Picture examines the ways movies and popular culture can foster a deeper awareness of the political dilemmas and debates shaping our world. Reviewing commercial films and documentaries, the text illustrates the myriad ways that film and popular culture shape our understanding of capitalism and democracy, war and terrorism, civil rights and social justice, campaigns and elections and the presidency. ...

La problématique de cette thèse concerne l'optimisation et l'évaluation de nouveaux systèmes d'aide à la communication pour personnes déficientes motrices. Ces travaux s'articulent autour de deux propositions : d'une part, l'optimisation de la disposition des caractères sur le clavier logiciel pour ainsi minimiser les déplacements à effectuer lors de saisie de texte en français , d'autre part, le système KeyGlass : celui-ci propose au fur et à...

Another no-holds-barred book to awaken our souls and kick ourselves into gear, from the "America's New Top Model" judge.

»Wie auf einem Schiff« fühlte sich Thomas Mann in seinem Niddener Ferienhaus. Und in der Tat können die drei Sommer 1930-1932, welche die Manns im Fischerdorf Nidden auf der Kurischen Nehrung verlebten, einer schmalen Halbinsel zwischen Ostsee und Kurischem Haff, als eine Art Vor-Exil gelten, bevor die Familie über den Ozean nach Amerika emigrierte. Zwei Generationen später entdeckt nun Frido Mann, der Enkel Thomas Manns, bei zahlreichen Besuc...

Dreimal kurz, dreimal lang, dreimal kurz. SOS. Jeder kennt das Morse-Alphabet.
