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. Ober die Pr}fung hinaus bleibt der Taschenatlas ein unentbehrlicher Studienbegleiter und ein zuverl{ssiges Nachschlagewerk.

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.

This handbook is intended for the advanced specialist and for the practitioner interested in the application of lasers in medicine. It provides state-of-the art summaries of all available medical laser systems and the indications for their clinical use. The first part introduces basic laser physics, including laser-tissue interactions as well as technical equipment and particular techniques developed for medical use in connection with laser. The second part of the text covers all areas of laser application in medicine presented by senior specialists from different countries, each having extensive practical experience.

A Greenhorn Naturalist in Borneo is about natural history, travel in the tropics, life sciences, and adventure, with the environment always in mind. It chronicles the nine years the author spent with his family on that equatorial island. The book’s humorous style never detracts from the focus on the science, the island of Borneo and its natural wonders.The story begins in 2007 on top of a garage in Taiwan, where the author kept a greenhouse filled with hundreds of carnivorous tropical pitcher plants. In August of the same year, he attended a conference on these plants in Borneo and met them in the wild for the first time. This triggered an obsession with the island’s legendary rainforest fauna and flora, and he decided to move to Borneo with his family for easier access to the jungle. In a tone reminiscent of Bill Bryson, Douglas Adams, and Gerald Durrell – funny, self-deprecating, but always satisfying for the science-minded reader – A Greenhorn Naturalist in Borneo documents the Breuer family's adventures with Borneo’s enormous biodiversity: flying snakes, venomous primates, parachuting frogs, pangolins, king cobras, orangutans, masters of mimicry and camouflage, the world's rarest lizard and the world’s longest snake.And these are just a fraction of the life forms the reader will meet. Adventure lurks behind every trail bend: toddler-sized monkeys terrorize night hikers, bearded jungle pigs hunt stray dogs, a giant python almost gets stepped on, and other encounters of the ‘not so funny when it happened’ kind. The reader will also meet the people inhabiting the island, such as Asia’s last rainforest nomads, quaint government officials, and former headhunting tribes that still proudly display their trophies above their fireplaces. Inevitably, the author’s life in Borneo also led to first-hand insight into the island’s environmental tragedy caused by decades of severe over-exploitation, a recurring topic throughout the book.A Greenhorn Naturalist in Borneo puts the reader in a front-row seat to marvel at nature’s wonders in all their magnificence visiting places unknown and creatures unheard of; and it is also an invitation to consider the state of the planet, to take it seriously, and to act before it’s too late.
