The herp is on Hans Breuer searches for a new pet ratsnake in Taipei restaurants, loses a coral snake in his living room, confronts a cobra in complete darkness, and assumes unorthodox yogic postures to photograph kraits, habus, and bamboo vipers. Between the tree ferns of Taiwan's lush, rugged mountains, Hans draws us along to experience a fantastic variety of snakes, along with turtles, civets, pangolins, and other representatives of the island's immense biodiversity. During his constant search for reptiles and amphibians, Hans introduces the best of Taiwan with quirky humor, while educating the reader in remarkable detail. Twenty-two years on the island, and fluency in Mandarin Chinese, has given Hans a broad experience with all facets of Taiwan life, complementing his herpetological observations. We learn about family relations, food and drinking customs, dealing with curious police officers, and the aboriginal relationship to Taiwan's rich animal life. With this book in hand, you don't need a plane ticket to enjoy the thrill of herping Taiwan, but after reading Hans' adventures, you might just book your next vacation there
The book is divided into two parts: Part I deals with the relevant physics and planning algorithms of protons (H Breuer) and Part II with the radiobiology, radiopathology and clinical outcomes of proton therapy and a comparison of proton therapy versus photon therapy (BJ Smit). Protons can be used for radiosurgery and general radio therapy. Since proton therapy was first proposed in 1946 by Wilson, about sixteen facilities have been built globally. Only a very few of these have isocentric beam delivery systems so that proton therapy is really only now in a position to be compared directly by means of randomised clinical trials, with modern photon radiotherapy therapy sys tems, both for radiosurgery and for general fractionated radiotherapy. Three-dimensional proton planning computer systems with image fusion (image of computerised tomography (CT), magnetic resonance registration) capabilities imaging (MRI), stereotactic angiograms and perhaps positron emission tomography (PET) are essential for accurate proton therapy planning. New planning systems for spot scanning are under development. Many of the older comparisons of the advantageous dose distributions for protons were made with parallel opposing or multiple co-planar field arrangements, which are now largely obsolete. New comparative plans are necessary once more because of the very rapid progress in 3-D conformal planning with photons. New cost-benefit analy ses may be needed. Low energy (about 70 MeV) proton therapy is eminently suitable for the treatment of eye tumours and has firmly established itself as very useful in this regard."

75 Farbtafeln und 125 zugeordnete Textseiten mit zahlreichen griffigen Beispielen und nahtloser Anlehnung an den Gegen- standskatalog machen den "Taschenatlas" zur idealen Vorbe- reitung auf die {rztliche Vorpr}fung. Im Dialog von klar ge- gliederter, konzentrierter Darstellung und dazugeh]rigen Schemazeichnungen werden auch komplexe Fakten schnell ver- standen und gemerkt, das Zusammenspiel von Physik und Physiologie immer wieder transparent. A-ber die Pr}fung hinaus bleibt der Taschenatlas ein unentbehrlicher Studienbegleiter und ein zuverl{ssiges Nachschlagewerk.
