This new wealth of high quality experimental data thus pre sents challenges of interpretation and organization of the data which the new developments in group theory strive to meet. The wealth and quality of this new data makes the nuances and differences implicit in the traditional strong and weak field approach testable.

The title of the Symposium was changed again this year by dropping the word "Holography" to reflect the further emphasis on the general imaging aspects of the Symposium and the de-emphasis on the Holographic aspects.

We present here the transcripts of lectures and talks which were delivered at the NATO ADVANCED STUDY INSTITUTE "Electrons in Disordered Hetals and at ~~etallic Surfaces" held at the State University of Ghent, Belgium between August 28 and September 9, 1978.

The discovery of materials which possess more complex crystal structures and thus more complicated phonon scattering mechanisms have brought innovative challenges to the theory and experimental understanding of these materials. This book will serve as a resource to the researchers in the field of thermal conductivity.

The problem of molecules interacting with metal surfaces has for a very long time been recognized to be of considerable technological as well as fundamental importance.

The role played by surface phenomena in the overall behavior of a material has been a subject for speculation for a long time, but only during the last decade or so have experimental and theor etical tools been developed which make it possible to investigate surface structure and related surface phenomena uniquely.

Providing insight and advice on young people's moral development, this book states that most forms of human interaction are laden with moral content. It provides recommendations for how adults can offer guidance to young people learning to negotiate life in a global society.

Microfossils are ideally suited to environmental studies because their short generation times allow them to respond rapidly to environmental change. This book represents an assessment of the progress made in environmental micropalaeontology and sets out future research directions.

Receptaculitids are extinct high-level fossils that provide a window into the history of life. After the discovery and analysis of a deposit of phosphatized receptaculitids on the Baltic Sea island of OEland, the authors conclude that receptaculitids possess an attribute not found in any other group of organisms, living or fossil.

The present volume is based on the proceedings of the 12th Workshop of the INFN ELOISATRON Project, held at the "Ettore Majorana" Centre for Scientific Culture (EMCSC), Erice (frapani), Sicily, Italy, in the period September 15-20, 1990.

Proceedings of a NATO ASI held in Cesme (Izmir), Turkey, August 27-September 7, 1989.

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.

This workshop was the second devoted to accelerator science. It focused on the best way to construct very-high-energy machines such as the Eloisatron in order to obtain the best results. Sixteen contributions also address RF and microwave systems and their acceleration problems. Annotation copyright Book News, Inc. Portland, Or.

During the past 15 years, quantum field theory and classical statistical mechanics have merged into a single field, and the need for nonperturbative methods for the description of critical phenomena in statistical mechanics as well as for problems in elementary particle physics are generally acknowledged. Such methods formed the central theme of the 1987 Cargese Advanced Study Institut. e on "Nonpert. urbat. ive Quantum Field Theory. " The use of conformal symmet. ry has been of central interest in recent years, and was a main subject at. t. he ASI. Conformal invariant quantum field theory describes statistical mechanical systems exactly at a critical point, and can be analysed to a remarkable ext. ent. by group t. heoretical methods. Very strong results have been obtained for 2-dimensional systems. Conformal field theory is also the basis of string theory, which offers some hope of providing a unified t. heory of all interactions between elementary particles. Accordingly, a number of lectures and seminars were presented on these two topics. After syst. ematic introductory lectures, conformal field theory on Riemann surfaces, orbifolds, sigma models, and application of loop group theory and Grassmannians were discussed, and some ideas on modular geometry were presented. Other lectures combined' traditional techniques of constructive quant. um field theory with new methods such as the use of index-t. heorems and infinite dimensional (Kac Moody) symmetry groups. The problems encountered in a quantum mechanical description of black holes were discussed in detail.

This volume contains the lectures and communications presented at the NATO Advanced Research Workshop on "Atomic and Molecular Processes with Short Intense Laser Pulses" (NATO ARW 848/86). The workshop was held at Bishop's University, Lennoxville, Que, Canada, July 19-24, 1987, under the directorship of Prof. A.D. Bandrauk, Universite de Sherbrooke. A scientific committee made up of Dr. P. Corkum (Laser Physics, ~ational Research Council of Canada), Dr. P. Hackett (Laser Chemistry, National Research Council of Canada), Prof. S.C. Wallace (Dept. of Chemistry and Physics, University of Toronto), and Prof. F.H.M. Faisal (FakultHt fUr Physik, UniversitHt Bellefeld) was called upon to invite and organize eminent lectures in the fields of i) Coherence Phenomena in Atomic and Molecular Photoprocesses. ii) High Intensity Atomic and Molecular Phenomena. iii) Laser Chemistry The aim of the workshop was to bring together chemists and physicists in order to~iscuss and analyze the progress made in the use of short in­ tense laser pulses in understanding coherence phenomena and high intensity, nonlin~adiative effects in atomic and molecular systems.

to the American Edition We are pleased that our modest work, published some time ago in Russian in Moscow* and which attracted the attention of polymer specialists,t will now be available to the EngJish­ speaking audience of scientists - chemists, physicists, and technologists engaged in creating new types of polymer materi­ als for modern technology and working on the fundamental prob­ lems of the solid-state physics and structure of polymer- due to the initiative of Plenum Press. In polymer science, the 1980s were marked by the birth of a new field and a new scientific trend related to the dis­ covery and study of a previously unknown class of polymers thermotropic liquid-crystalline polymers - and the further development of the fundamental theoretical concepts of the liquid-crystalline (mesomorphic) state of macromolecular com­ pounds. This state is a phase state in thermodynamic equi­ librium characterized by the anisotropy of the structure and properties as a result of one-dimensional or two-dimensional ordering. Such systems have an ordered but simultaneously labile structure which can easily be altered by mechanical, electrical, or magnetic fields; the polymer system then acquires unique physical and optical properties. These prop­ erties, which are acquired in the liquid-crvstalline state, are then fixed in the solid at the operating temperatures. *N. A. Plate and V. P. Shibaev.

In recent years, a new field of nuclear research has been opened through the possibility of studying nuclei wi\h very large values of angular momentum, temperature, pressure and number of particles.

Four years after a first meeting in BADDECK, Canada, on the Physics of Ion-Ion and Electron-Ion collisions, a second Nato Advanced Study Institute, in HAl~/Lesse, Belgium, reexamined the subject which had become almost a new one, in consideration of the many important developments that had occured in the mean time. The developments have been particularly impressive in two areas : the di-electronic recombination of electrons with ions and the collisional processes of mUltiply charged ions. For dielectronic recombination, a major event was the obtainment, in 1983, of the first experimental data. This provided, at last, a non speculative basis for the study of that intricate and subtle process and strongly stimulated the theoretical activities. Multiply charged ions, on the other hand, have become popular, thanks to the development of powerful ion sources. This circumstance, together with a pressing demand from thermonuclear research for ionisation and charge exchange cross sections, has triggered systematic experimental investigations and new theoretical studies, which have contributed to considerably enlarge, over the last five years, our understanding of the collisional processes of multiply charged ions. Dielectronic recombination and multiply charged ions were therefore central points in the programme of the A.S.I. in HAN/Lesse and are given a corresponding emphasis in the present book.

Thi's book collects the contributions to the NATO Advanced Research WJrkshop on "FundaIrental Aspects of Quantum 'Iheory", held at the Centro di Cultura Scientifica "Alessandro Volta", Villa Olma, Carro, Italy, 2-7 September 1985. The rreeting was dedicated to the rremory of the late pro­ fessor Piero Caldirola, a prominent member of the Physics Departrrent of the University of r1ilan and a native of Como. The aim of the workshop has been to present several recent experi­ rrental results and theoretical developrrents concerning the various fa­ cets of quantum physics. The breadth of scope of the rreeting was in accordance with Professor Caldirola's vast scientific interests, and fostered communication among experirrental physicists, theoretical and mathematical physicists, and nEthematicians, working in different but related fields. Indeed, lectu­ rers endeavoured to make their contributions understandable to people acquainted with the problem but not necessarily familiar with the tech­ nical details; and these efforts were successful, as indicated by the frequent private discussions which took place among participants belon­ ging to different breeds and brands. 1ne rreeting was made up of six one-day sessions, each of them addres­ sing to a specific aspect of quantum theory: 1. General Problems and Crucial Experinents; with emphasis on sin­ gle-particle interference eh~rirrents of neutrons and of photons, and on the rreasurerrent problem. 2. Quantization and Stochastic Processes; including stochastic quan­ tization of gauge fields, stochastic description of supersyrnmetric fields, quantum stochastic calculus and stochastic mechanics.
