Bioremediation - the use of microorganisms for environmental clean-up - is a technology that is experiencing a rapid phase of development. From the opening chapter of Perspectives in Bioremediation, on the nature of environmental site assessment, on to the genetic manipulation of native soil microorganisms, the international collection of authors provide an understanding of the current progress and limitations of technologies that are designed to help nature herself. The book draws together many different aspects of environmental remediation: the environmental engineer is introduced to the bacteria of contaminated environments and the ideas developing from genetic engineering; the environmental microbiologist can grasp site assessment and the predictive kinetic analysis of potentials. The book provides a clear and concise introduction to the nature of and potential for bioremediation to contribute to a critical global effort in eliminating contamination of the world's resources and to start to reverse decades of environmental mismanagement and neglect.

The metals industry was established in the Ural Mountains over two centuries ago. Seventy years ago, the town of Magnitogorsk was established, with US and Western assistance, to exploit the iron ore there. It became a symbol of USSR industry - and is now a symbol of air pollution. This volume describes the pollution in the region and the steps being taken to combat it.

Historically, one of the basic issues in control systems design has been robustness: the ability of a controlled plant to withstand variations in or lack of knowledge of its dynamics. Even if the dynamics of a system are accurately known for purposes of implementation, it is often desirable to design a control system based on a simplified model. Consequently it is essential to be able to guarantee a reasonable performance not only for the nominal plant, but also for its neighbouring perturbations: this is the issue of robustness. Since the beginning of this decade major advances have been made in this area, notably using the H -approach; this term is meant to cover the solution of sensitivity reduction, approximation and model reduction, robustness and related control design problems using the mathematics of Hardy spaces and related areas in Harmonic Analysis. This book contains the proceedings of the NATO Advanced Research Workshop on "Modelling, Robustness and Sensitivity Reduction in Control Systems", which was held at the University of Groningen, December 1986. Its aim was to explore the development of H -design techniques and its ramifications in Systems Theory in a unified and systematic way with the emphasis on recent advances and future directions in this fast developing area. In particular the following inter-related aspects were addressed: H -mathematical foundations, model approximation and robustness in control design, optimal sensitivity reduction, modelling and system identification and signal processing.

NATO's Division of Scientific and Environmental Affairs sponsored this Advan­ ced Study Institute because it was felt to be timely to cover this important and challengjng subject for the first time in the framework of NATO's ASI programme. The significance of real-time systems in everyones' life is rapidly growing. The vast spectrum of these systems can be characterised by just a few examples of increasing complexity: controllers in washing machines, air traffic control systems, control and safety systems of nuclear power plants and, finally, future military systems like the Strategic Defense Initiative (SDI). The import­ ance of such systems for the well-being of people requires considerable efforts in research and development of highly reliable real-time systems. Furthermore, the competitiveness and prosperity of entire nations now depend on the early app­ lication and efficient utilisation of computer integrated manufacturing systems (CIM), of which real-time systems are an essential and decisive part. Owing to its key significance in computerised defence systems, real-time computing has also a special importance for the Alliance. The early research and development activities in this field in the 1960s and 1970s aimed towards improving the then unsatisfactory software situation. Thus, the first high-level real-time languages were defined and developed: RTL/2, Coral 66, Procol, LTR, and PEARL. In close connection with these language develop­ ments and with the utilisation of special purpose process control peripherals, the research on real-time operating systems advanced considerably.

Constraint programming is like an octopus spreading its tentacles into databases, operations research, artificial intelligence, and many other areas. The concept of constraint programming was introduced in artificial intelligence and graphics in the 1960s and 1970s. Now the related techniques are used and studied in many fields of computing. Different aspects of constraint processing are investigated in theoretical computer science, logic programming, knowledge representation, operations research, and related application domains. Constraint programming has been included in the lists of related topics of many conferences. Nevertheless, only in 1993 were the first forums held, devoted as a whole to this field of knowledge. These were the First Workshop on Principles and Practice of Constraint Programming (PPCP'93) which was held in Newport, Rhode Island, USA, April 28-30, the International Workshop on Constraint Processing (at CSAM'93) held in St. Petersburg, Russia, July 20-21, and the NATO Advanced Study Institute (NATO AS!) on Constraint Programming held in Parnu, Estonia, August 13-24. NATO A Sis are aimed to be schools bringing together leading researchers and practitioners from industry and academia in some area of knowledge to provide a concise picture of the work done and results obtained by different groups. This is intended for dissemination of advanced knowledge not yet taught regularly in of new topics university. However, ASis must also encourage the introduction into university curricula as well as foster international scientific contacts.

This volume is an outgrowth of a NATO Advanced Research Workshop on "Expert Judgment and Expert Systems," held in Porto, Portugal, August 1986. Support for the Workshop was provided by the NATO Division of Scientific Affairs, the U.S. Army Research Institute, and the U.S. National Science Foundation. The Workshop brought together researchers from the fields of psychology, decision analysis, and artificial intelligence. The purposes were to assess similarities, differences, and complementarities among the three approaches to the study of expert judgment; to evaluate their relative strengths and weaknesses; and to propose profitable linkages between them. Each of the papers in the present volume is directed toward one or more of those goals. We wish to express our appreciation and thanks to the following persons for their support and assistance: John Adams, Vincent T. Covello, Luis da Cunha, Claire Jeseo, B. Michael Kantrowitz, Margaret Lally, Judith Orasanu, R. M. Rodrigues, and Sandor P. Schuman.

During its existence the Ecosciences Panel of the North Atlantic Treaty Organisation was constantly concerned with (i) the communic­ ation gap between the generators of ecological/environmental infor­ mation and those who use it and (ii) the narrow interpretation of 'environmental' which too frequently was taken as being synonymous with pollution. Because of this concern, and because the panel recognised that land-use is perhaps the overriding facet of environmental policy it was decided to arrange the Seminar recorded in this volume :- Land and its Uses : Actual and Potential An Environmental Appraisal The development of this Seminar was chaired by Professor F. T. Last who was enthusiastically supported by B. G. Bell (U.K.), Drs S. Bie (Norway), 0. W. Heal (U.K.), R. Herrmann (Federal Republic of Germany), M.C.B.Hotz (formerly of NATO, Belgium, but now in Canada), L. Munn (Canada) and N. Yassoglou (Greece). Together, they decided that the participants should include (i) planners/decision­ makers and (ii) scientists generating ecological/environmental infor­ mation, in the hope that they would gain a better understanding of each others problems and attitudes and as a result identify how information can be prepared in a more usable form.

The Advanced Research Institute on "Health Services Systems" was held under the auspices of the NATO Special Programme Panel on Systems Science as a part of the NATO Science Committee's continuous effort to promote the advancement of science through international cooperation. A special word is said in this respect supra by Pro­ fessor Checkland, Chairman of the Systems Science Panel. The Advanced Research Institute (ARI) was organized for the purpose of bringing together senior scientists to seek a consensus on the assessment of the present state of knowledge on the specific topic of "health services systems" and to present views and recom­ mendations for future health services research directions, which should be of value to both the scientific community and the people in charge of reorienting health services. The conference was structured so as to permit the assembly of a variety of complementary viewpoints through intensive group discussions to be the basis of this final report. Invitees were selected from allover Europe and North America, including observers from the major international organizations involved in health ser­ vices research, to provide the experience and expertise necessary to make the issue of "health services systems" val id and significant.

This is the 3rd Course that has been organized at the presti­ gious E. Majorana Centre. The choice of the theme is not a casual one. In fact after rehabilitation and prevention which were the topics discussed in the previous courses of 1979 and 1982, this Course deals with subjects more deeply connected with the mechanisms of cardiac function and the pathological aspects that under this point of view characterize many specific diseases. The rapid development in the application of technology to the problems of Cardiological diagnosis has made it possible to study ventricular function in the evaluation of patients with apparent or suspected heart disease. Knowing that we are facing one of the most complex subjects in modern cardiology we wish to arouse the interest of researchers anrl cardiologists by comparing different experiences with the aim of giving an overall survey of the problems. The program has been divided into 4 chapters: 1. Systolic and diastolic ventricular function. 2. Specific studies of ventricular function using invasive and non­ invasive techniques. 3. Diseases with altered ventricular function. 4. Pharmacological manipulation of ventricular function. Our aim is not only to stimulate useful discussions in the faculty but also among the participants. I hope that we can achieve this. I should like to take this opportunity of thanking the co­ directors of the Course Prof. Jan Kellermann and Prof. Robert v vi PREFACE Leachman who have played an important part in the scientific organization.
