The Boundary Element Method, or BEM, is a powerful numerical analysis tool with particular advantages over other analytical methods. With research in this area increasing rapidly and more uses for the method appearing, this timely book provides a full chronological review of all techniques that have been proposed so far, covering not only the fundamentals of the BEM but also a wealth of information on related computational analysis techniques and formulations, and their applications in engineering, physics and mathematics. An indispensable handbook and source of inspiration for researchers and professionals in these fields, this book is also an ideal textbook for graduate engineering students.

ELOISATRON (Eurasiatic Long Intersecting Storage Accelerator) is the name of a research and development project in the field of high energy physics, approved and funded by the Instituto Nazionale di Fisica Nucleare INFN in Italy. The main objective of the project is to conduct research and development studies to promote the construction of a (100 + 100) TeV proton-proton collider in Europe. The present volume contains the proceedings of the 4th INFN ELOISATRON project workshop, held on the topic: New Aspects of High-Energy Proton-Proton Collisions. The workshop took place at the Centro Internazionale di Cultura Scien- tifica "Ettore Majorana" (CCSEM), Erice-Trapani, Sicily, Italy, in the period May 31-June 7, 1987. This was the first workshop in this series which concentrated on physics issues in proton-proton collisions with 1-100 TeV beams; the earlier three INFN ELOISATRON workshops, held at Erice during 1986 and 1987, had mostly dealt with technical issues related to the accelerator and detector aspects of high en- ergy hadron colliders.The present workshop was supported by the Italian Ministry of Education, the Italian Ministry of Scientific and Technological Research, the Sicilian Regional Government and the Ettore Majorana Centre for Scientific Culture. With the successful operation of the CERN Superconducting antiproton-proton Synchrotron (SppS), resulting in the discoveries of the vector bosons W and Z and providing evidence for new aspects of flavour mixings, the interest in very high energy proton beams as probes of fundamental phenomena in nature has mounted worldwide.

The present volume is based on the proceedings of the 6th and 7th INFN ELOISATRON project workshops, held at the Centro di Cultura Scientifica "Et- tore Majorana" CCSEM, Erice-Trapani, Sicily, Italy, in the period June 10-27, 1988. The topics of the two workshops were, respectively: * Heavy Flavours: Status and Perspectives, and * Novel Features of High Energy Collisions in 1-100 TeV Region. They were attended by sixty-three physicists. The two workshops were followed by a meeting of the INFN ELOISATRON working group, also held at the CCSEM in the period October 7-15, 1988 in which twenty-five physicists participated. Since there was quite a bit of overlap among speakers, participants and the topics covered at the three meetings, we have decided to issue ajoint proceeding, with the first part entitled: Heavy Flavour Physics, and the second: High Energy Physics with 1-100 Te V Proton Beams. Some of the reports included in this volume have been contributed by the INFN ELOISATRON working group members. The first. part of these proceedings deals mostly with the presentation and inter- pretation of results in t.he so-called fiavour physics sector.New results, which have become available in the last three years from experiments involving kaons, charmed and beauty hadrons, and searches for the still missing top quark at the present and fothcoming colliders are topics of major interest. here. The contributions in this part are organized in three categories: Experimental Results, Theoretical Interpretation, and Future Directions.

The present volume is based on the proceedings of the 9th INFN ELOISATRON Project workshop held at the Ettore Majorana Centre for Scien- tific Culture, Erice-Trapani, Italy, in the period July 15-26, 1989. The topic of this workshop was: Higgs Particles - Physics Issues and Experimental Searches in High Energy Collisions and it was attended by over forty participants. The concept of Higgs mechanism, like most other scientific ideas, evolved over several years, with many independent and important contribu- tions in the sixtees to which Peter Higgs has referred in his historical account in these proceedings. However, it was not until 1967, paraphra- sing Weinberg, that "the right ideas were applied to the right problem"! Higgs mechanism, i.e. spontaneous breaking of local gauge symmetries with scalar particles becoming the longitudinal degrees of freedom of {other- wise) massless vector bosons and hence making them massive, is now an integral part of the standard {Glashow-Salam Weinberg) theory of electro- weak interactions. Fortunately for us, the structure of the standard theory prevents at least one scalar field from being transformed away.This is the Higgs particle in the standard theory - whose physics and search strategies are the subject of this workshop.

The M.A.B. BÉG MEMORIAL VOLUME is based on scientific articles written in honor of the late Mirza Abdul Baqi Bég, a professor of physics at the Rockefeller University, New York. The contributed articles are partly based on talks given at the school on high energy physics and cosmology, held March 11 - 25, 1990 at the Quaid-i-Azam University, Islamabad, Pakistan, and partly on articles contributed by his colleagues and collaborators.Being a scientific tribute to Bég, the articles reflect the specific areas of his scientific research and the contemporary trends and open questions in elementary particle physics. Deciphering the mechanism of symmetry breaking with the help of known properties of elementary particles - their masses and couplings — and devising new experimental tests to find clues to the actual physical phenomena at work, are the recurring themes in this book. The role of higher symmetries, formulated in terms of the string and grand unified theories, likewise is elucidated in several articles.The book also contains one of the last articles authored by Bég, written in honor of Luigi Radicati, describing a scientific history of the crucial development from the quark model to the standard model which took place in the sixties.

This is a selection from over 250 papers published by Abdus Salam. Professor Salam has been Professor of Theoretical Physics at Imperial College, London and Director of the International Centre for Theoretical Physics in Trieste, for which he was largely responsible for creating. He is one of the most distinguished theoretical physicists of his generation and won the Nobel Prize for Physics in 1979 for his work on the unification of electromagnetic and weak interactions. He is well known for his deep interest in the development of scientific research in the third world (to which ICTP is devoted) and has taken a leading part in setting up the Third World Academy. His research work has ranged widely over quantum field theory and all aspects of the theory of elementary particles and more recently into other fields, including high-temperature superconductivity and theoretical biology. The papers selected represent a cross section of his work covering the entire period of 50 years from his student days to the present.
