After earlier meetings in Enschede (NL, 1994), Basel (CH, 1996) and Banff (CDN, 1998), muTAS 2000 is the fourth international symposium on the subject of miniaturized techniques, methods, devices and systems for (bio)chemical analysis and synthesis. Initially started as a minor sub-topic in the large field of Micro System Technology (MST or MEMS), the field of muTAS is currently generally considered as one of the most important application areas of MST, which is reflected in the still rapidly growing research, development, and, above all, commercialization activities. Apart from further development and refining of the research on electrophoretic separation, electrokinetically driven flow systems, cell manipulation and analysis, miniaturized flow systems and study of microfluidics, the important new area of centrifugal microfluidics on CD devices receives broad attention. On the other hand, new innovations range from topics as exotic as photoacoustic detection in microreactors and molecular emission detection on a chip to very high-pressure microreactor devices and shear-flow driven separations. The enormous speed of the developments in this field is illustrated by the large number of new start-up companies, some of them based upon technologies that were not even published at the former meeting in Banff in 1998. All this illustrates the great excitement that continues to govern this field in which generation and analysis of (bio)chemical information using microtechnology becomes more and more entangled in what one could call micro (bio)chemical systems. This volume contains the proceedings of the fourth international symposium on Micro Total Analysis Systems (muTAS 2000), held 14-18 May 2000, at the University of Twente in Enschede, The Netherlands, and organised by the MESA+ Research Institute. Cutting-edge research of all invited and contributed papers presented by the world's leading &mgr;TAS groups provide the newest state of the art of this electrifying, multidisciplinary field.

The proceedings of the Fifth International Conference on Miniaturized Chemical and Biochemical Analysis Systems documents the exciting progress being made in this field of research and the continuing success of the conference series. The previous meetings have shown nearly 100% growth in abstract submissions and the fifth of the series continues this trend with nearly 400 abstracts submitted. Simultaneously the quality of the papers in this meeting remains high, as demonstrated in this publication. A broad array of topics is covered in this volume, as would be anticipated for such a highly multidisciplinary field as represented by muTotal Analysis Systems or Lab-on-a-Chip technology, the terms most commonly used to describe microfabricated devices for performing chemical and biochemical experimentation. The field remains heavily focused on microfluidic systems with only a few exceptions addressing gas phase studies. Device and system developments that address measurement problems associated with biotechnology continue to be an emphasis. The profile of electrokinetic-based separation devices for the analysis of DNA and proteins remains high and the interest in devices for cellular analysis is showing considerable growth. Further development of components and strategies for fluid transport, mixing, and dispensing are highlighted. Detection technologies that specifically address quantification issues in chemical and biochemical microsystems became a new emphasis for this meeting. Several new optical detection techniques relevant to microfluid systems are illustrated and microscale versions of NMR probes and mass spectrometers are discussed. New areas of development that are potentiallyemerging are nanofluidics- and microfluidics-based chemical synthesis. Clearly the field of miniaturized chemical and biochemical analysis systems is vibrant and continues to rapidly grow in depth, breadth, and maturity. This volume contains the proceedings of the Fifth International Conference on Miniaturized Chemical and Biochemical Analysis Systems (&mgr;TAS 2001), held in Monterey, California, on October 21&endash;25, 2001. The collection of papers included in the proceedings represents the current state of the art in microsystems for chemical and biochemical experimentation. These proceedings will be a valuable tool for those wanting to become knowledgeable in an exciting field that may well change the way experimental problems in chemistry and biology are approached in the future.

Micro-TAS '98 is the third of a series of symposia initiated by MBSA (University of Twente) in 1994, on the subject of miniaturizing, and integrating within a monolithic structure, the chemical, biochemical and biological procedures commonly used for analysis and synthesis. The primary tool used to develop micro-total analysis systems (mu- TAS) has been micro-photolithographic patterning and micromachining. These powerful tools of Micro System Technology (MST or MEMS) have been applied in highly imaginative ways to develop microchip chemical arrays, fully integrated pump and fluid manifolds, and electrokinetically driven micro-channel systems to be used for genetic analysis, clinical diagnostics and environmental monitoring, and to integrate reactions as diverse as the polymerase chain reaction (PCR) and the large volume, partial oxidation of ammonia. This text illustrates the rapid expansion of the field, the extensive industrial involvement, the increasing number of participating researchers, the expanding range of concepts and applications that utilize MST and microfluidic devices, and new MST-compatible plastic micro-machining to meet the needs of the life science community. This volume contains the proceedings of the Third International Symposium on Micro-Total Analysis Systems, mu-TAS '98, held on October 13-16 in Banff, Alberta, Canada. State-of-the-art invited and contributed papers presented by the world's leading mu- TAS research groups provide a highly informative picture of the growth since 1994 and of the promising future of this exciting and rapidly growing field.

In the rapidly developing information society there is an ever-growing demand for information-supplying elements or sensors. The technology to fabricate such sensors has grown in the past few decades from a skilful activity to a mature area of scientific research and technological development. In this process, the use of silicon-based techniques has appeared to be of crucial importance, as it introduced standardized (mass) fabrication techniques, created the possibility of integrated electronics, allowed for new transduction principles, and enabled the realization of micromechanical structures for sensing or actuation. Such micromechanical structures are particularly well-suited to realize complex microsystems that improve the performance of individual sensors. Currently, a variety of sensor areas ranging from optical to magnetic and from micromechanical to (bio)chemical sensors has reached a high level of sophistication. In this MESA Monograph the proceedings of the Dutch Sensor Conference, an initiative of the Technology Foundation (STW), held at the University of Twente on March 2-3, 1998, are compiled. It comprises all the oral and poster contributions of the conference, and gives an excellent overview of the state of the art of Dutch sensor research and development. Apart from Dutch work, the contributions of two external invited experts from Switzerland are included.

The Sixth International Conference on Miniaturized Chemical and Biochemical Analysis Systems, known as /JTAS2002, will be fully dedicated to the latest scientific and technological developments in the field of miniaturized devices and systems for realizing not only chemical and biochemical analysis but also synthesis. The first /JTAS meeting was held in Enschede in 1994 with approximately 160 participants, bringing together the scientists with background in analytical and biochemistry with those with Micro Electro Mechanical Systems (MEMS) in one workshop. We are grateful to Piet Bergveld and Albert van den Berg of MESA Research Institute of the University of Twente for their great efforts to arrange this exciting first meeting. The policy of the meeting was succeeded by late Prof. Dr. Michael Widmer in the second meeting, /JTAS'96 held in Basel with 275 participants. The first two meetings were held as informal workshops. From the third workshop, /JTAS'98 (420 participants) held in Banff, the workshop had become a worldwide conference. Participants continued to increase in /JTAS2000 (about 500 participants) held in Enschede and /JTAS2001 (about 700 participants) held in Monterey. The number of submitted papers also dramatically increased in this period from 130 in 1998, 230 in 2000 to nearly 400 in 2001. From 2001, /JTAS became an annual symposium. The steering committee meeting held in Monterey, confrrmed the policy of former /JTAS that quality rather than quantity would be the key-point and that the parallel-session format throughout the 3.

The MESA Research Institute of the University of Twente was created in 1990 through the joining of the research unit Sensors and Actuators with the department of Microelectronics. The multidisciplinary institute, with participation from the faculties of Electrical Engineering, Applied Physics and Chemical Technology, was recently recognized as a Centre of Excellence by the Dutch Science Foundation. It is fully 2 equipped with modem Clean Room facilities (1000 m ) and a number of research laboratories. The objective of MESA is to perform research and development of systems in modem information technology, and on the units on which they are based: the microstructures that process and transduce signals. The institute gradually expanded during the past few years till some 125 persons in 1994. Given the wide variety of research subjects within MESA, it has been decided to start a MESA Monographs series, appearing on a more or less regular, yearly basis. In this way, after some time a good overview of research topics under investigation at MESA will be obtained. The first volume of this series coincides with the Proceedings of pTAS '94, the first Workshop on Micro Total Analysis Systems, held on November 21-22 at the University of Twente in Enschede, The Netherlands. IlTAS has recently been defined as the first strategic research orientation of MESA, aiming at synergetic collaboration between the different disciplines present in MESA.

This volume has been prepared in the framework of Project 1: "Educating Man for the 21st Century" of Plan Europe 2000, sponsored by the European Cultural Foundation. While most of the studies launched under this Project deal with specific aspects or levels of education the present volume attempts to provide a more global view of educational futures and their relationships to alternative futures of the overall socio-economic system. It should not be considered as a general integration or synthesis* of the different studies of the Education Project of the European Cultural Foundation - although it draws on them as well as other recently published documents. Rather, it should be regarded as one of several possible approaches, analytical tools, and incentives to the study and open discussion of educational problems seen in a long-term perspective. The volume is the result of a collective effort of a multinational team of researchers. A colloquium of some sixty participants, meeting at the Uni versity of York in October 1972, provided critiques and comments to the first version of the report. But only the authors themselves claim responsibil ity for the methodology of the study, and the opinions and conclusions expressed therein. These do not necessarily reflect those of the sponsors of the volume, the European Cultural Foundation and the Scientific Committee of its Education Project. * Such a synthesis will appear as the concluding report of the Project.

As in previous years the "Yearbook Commercial Arbitration 1994" treats current developments in international commercial arbitration - recent changes in arbitration legislation - newly enacted arbitration rules - applications of the UNCITRAL Model Law - arbitral awards (ensured confidentiality) - relevant court decisions of a general nature and - the New York Arbitration Convention of 1958 in addition to the Washington and European Conventions The Yearbook, which is compiled with the assistance of a worldwide network of correspondents, contains in its 19th volume a broad selection of arbitral awards, including awards issued under the auspices of ICSID, ICC, and the Iran-U.S. Claims Tribunal. A topic which has received special attention in this year's Yearbook is the issue of corruption or "facilitating payments". This volume of the Yearbook also features a Consolidated Commentary on the 1958 New York Convention by Prof. Albert Jan van den Berg, reviewing the court decisions published in the Yearbook in the period 1992-1994. Subscribers to the Yearbook receive this yearly up-date on developments and decisions in the sphere of commercial arbitration automatically.

The reports and commentaries in this volume, covering the entire process of arbitration from pre-arbitral stage to the post-arbitral stage, reflect changes in the economic and ppolitical structure. They contain both general overviews of the current situation, as well as detailed observations. The commentators were selected from legal systems and institutions where international commercial arbitration is firmly established, as well as from legal systems where the former tentative position of international commercial arbitration is only now being strengthened by means of acceptance by governments, ratification of multilateral arbitration conventions, enacting of new legislation and the establishment of new arbitral institutions.

Discussing the main issues in Dutch arbitration law, its history and its procedures, this text includes coverage of current developments, such as the privatization of the administration of justice, recent legal decisions and publications. This edition also contains chapters on international arbitration and arbitration outside the Netherlands. The book should be of value to non-jurists studying law and beginning law students, as well as to arbitrators and practising lawyers.
