Taschenbuch. Condizione: Neu. Neuware - This book is the result of the authors' many years of experience in using neurosurgical lasers. They began using laser diodes in their speciality at the start of the 1990s, making them pioneers in the field. The first part of the book deals with the general physical bases and comparative bio-tissue effects of the various kinds of surgical laser, safety measures required and legislation concerning powerful lasers. The second part focuses on laser diodes alone. The authors describe in detail how they use them to operate on intracranial and intraspinal tumours, in intraventricular endoscopy, and in surgery involving epilepsy. Details are given of: technical data; the choice of parameters depending on how the lasers are used (contact and non-contact, and the type of lesion being operated on) as well as their indications in neurosurgery. The authors emphasise the practical recommendations that make this book a valuable companion for current and potential users working in neurosurgery and other surgical applications. They also mention the new and future uses of laser diodes which are currently being developed and which show that this equipment really does represent a new generation of lasers. About 100 colour illustrations and tables are used to explain and underscore the authors' points.…

Taschenbuch. Condizione: Neu. Neuware - Axel Kahn's book, published late in 1996, which provided an overview of the opinions expressed by the Commission of Biomolecular Engineering about genetically modified plants, was a great success. Given the scale and importance of the phenomenon, the French Ministry of Agriculture and publishers John Libbey Eurotext have decided to publish an English-language version of this fundamental book about the introduction and development of genetically modified plants. For some years now, plant biotechnology, especially genetic engineering, has enabled us to modify the cycle of plant production, strengthening resistance to weedkillers and pests, improving yields and quality, adapting plants to unfavourable environments and creating new species. In France, the Biomolecular Engineering Commission (CGB) is responsible for authorising the marketing of these modified products. Over the past ten years it has certified 450 new products for public consumption. This book, which is suitable for the general public, reports on the experience acquired by the CGB and the studies it has conducted: What are the potential risks associated with so-called transgenetic plants Are there any undetectable phenomena involved - How can such plants be produced more safely Axel Kahn is a world-renowned geneticist and clinician, chaired the Biomolecular Engineering Commission until 1998. Here he explains the 'philosophy' of the CGB, which has gained unrivalled experience in Europe, and sets out ethical and scientific guidelines for the use of genetic engineering techniques.…

Taschenbuch. Condizione: Neu. Neuware - As in previous years, the editors have selected topics which are rapidly developing and for which there is a need to communicate new information. For Roma 99 they have chosen nine topics, each subject to a pair of presentations, the first on new disease mechanisms and the second on recent development in clinical management.…
