Nuclear technology in all countries of the world is subject to controls from the International Atomic Energy Agency (IAEA) to prevent its misuse for military purposes. Recently these controls (or "safeguards") have come under criticism for lack of effectiveness, and the IAEA has now elaborated a strengthened safeguards system reaching deep into the domains of national sovereignty. Problems and prospects of the new system are discussed in this book by a team of German and international scholars, practitioners and officials.

This book presents an interdisciplinary collection of expert analyses and views of existing verification systems. It provides guidelines and advice for the improvement of those systems as well as for new challenges in the field.

Cardiovascular drug therapy has markedly progressed in the recent decades. Not only have new drugs been introduced to clinical practice, but new classes of drugs have been developed. While in 1960 the practicing cardiolo gist had a selection of about only ten drugs, in 1987 about 150 drugs are routinely used in cardiovascular diseases. Elderly patients, however, usually do not enjoy the full benefit of this progress. This might be due to lack of knowledge, a conservative approach, or the worldwide tendency not to try new drugs in the elderly. It is now clear that the majority of patients that will be treated in car diovascular clinics will be, in the near future, elderly patients. Even now, elderly patients form about one-third of the patients with cardiovascular diseases. These patients are approached, however, according to criteria devel oped for younger populations. This is despite the fact that elderly patients differ from younger ones in most aspects, including pathology, epidemiol ogy, pathophysiology, diagnostic approach, management, pharmacology, pharmacokinetics, rehabilitation, and supportive treatment. It is the purpose of this book to present to the clinician all drugs with which there is clinical experience in the elderly or which might be potentially useful for the elderly with cardiovascular diseases. The data are presented without the authors taking a position. This should allow the clinicians to make their own selection and individualize treatment, vii viii Preface based on a wide data base. Comparative data are presented only when specific comparative studies were performed."

This book brings together and updates the latest information on the diversity of yeasts, their molecular features and their applications in the welfare of mankind. Yeasts are eukaryotic microfungi widely found in natural environments, including those with extreme conditions such as low temperatures, low oxygen levels and low water availability. To date, approximately 2,000 of the estimated 30,000 to 45,000 species of yeast on Earth, belonging to around 200 genera have been described. Although there are a few that are opportunistic human and animal pathogens, the vast majority of yeasts are beneficial, playing an important role in the food chain and in the carbon, nitrogen and sulphur cycles. In addition, yeasts such as Saccharomyces cerevisiae, Hansenula polymorpha and Pichia pastoris are used in expressing foreign genes to produce proteins of pharmaceutical interest. A landmark in biotechnology was reached in 1996 with the completion of sequencing of the entire S. cerevisiae genome, and it has now become a central player in the development of an entirely new approach to biological research and synthetic biology. The sequencing of genomes of several yeasts including Schizosaccharomyces pombe, Candida albicans and Cryptococcus neofromans has also recently been completed.

Automation is nothing new to industry. It has a long tradition on the factory floor, where its constant objective has been to increase the productivity of manufacturing processes. Only with the advent of computers could the focus of automation widen to include administrative and information-handling tasks. More recently, automation has been extended to the more intellectual tasks of production planning and control, material and resource planning, engineering design, and quality control. New challenges arise in the form of flexible manu facturing, assembly automation, and automated floor vehicles, to name just a few. The sheer complexity of the problems as well as the state of the art has led scientists and engineers to concentrate on issues that could easily be isolated. For example, it was much simpler to build CAD systems whose sole objective was to ease the task of drawing, rather than to worry at the same time about how the design results could be interfaced with the manufacturing or assembly processes. It was less problematic to gather statistics from quality control and to print reports than to react immediately to first hints of irregularities by inter facing with the designers or manufacturing control, or, even better, by auto matically diagnosing the causes from the design and planning data. A heav- though perhaps unavoidable - price must today be paid whenever one tries to assemble these isolated solutions into a larger, integrated system."

This book strives to take stock of current achievements and existing challenges in nuclear verification, identify the available information and gaps that can act as drivers for exploring new approaches to verification strategies and technologies. With the practical application of the systems concept to nuclear disarmament scenarios and other, non-nuclear verification fields, it investigates, where greater transparency and confidence could be achieved in pursuit of new national or international nonproliferation and arms reduction efforts. A final discussion looks at how, in the absence of formal government-to-government negotiations, experts can take practical steps to advance the technical development of these concepts.
