Reed (Princeton University)on "The GNS Construction -- A Pedagogical Example": infinite tensor products of Hilbert spaces; the canonical anti-commutation relations; the example; the example -- via the GNS construction.Bruno Zumino (CERN, European Organization for Nuclear Research) on "Effective Lagrangians and Broken Symmetries": Introduction; effective action and phenomenological fields; Ward identities and the effective action; Goldstone's theorem; non-linear realizations; massive Yang-Mills fields as phenomenological fields; broken scale invariance; the fifteen parameter conformal group and the Weyl transformations; conversion identities and trace identities; invariant actions; SU(3)xSU(3)and conformalinvariance; strong gravitation; concluding remarks.

The first volume of the Brandeis University Summer Institute lecture series of 1970 on theories of interacting elementary particles, consisting of four sets of lectures. Every summer since 1959 Brandeis University has conducted a lecture series centered on various areas of theoretical physics. The areas are sufficiently broad to interest a large number of physicists and the lecturers are among the original explorers of these areas. The 1970 lectures, presented in two volumes, are on theories of interacting elementary particles. The four lecturers of Volume 1, and the range of the topics they cover, are as follows: Stephen L. Adler (Institute for Advanced Study) on "Perturbation Theory Anomalies": introduction and review of perturbation theory; the VVA triangle anomaly; absence of radiative corrections; generalizations of our results; connection between Ward identity anomalies and commutator (Bjorken-limit) anomalies; applications of the Bjorken limit; and breakdown of the Bjorken limit in perturbation theory. Stanley Mandelstam (University of California at Berkeley) on "Dynamical Applications of the Veneziano formula for the four-point scalar amplitude; factorization; the operator formalism; Veneziano-type quark models; and higher-order Feynman-like diagrams. Steven Weinberg (Massachusetts Institute of Technology) on "Dynamic and Algebraic Symmetries": Introduction; hadron electrodynamics; local symmetries; and chirality. Wolfhart Zimmermann (New York University) on "Local Operator Products and Renormalization in Quantum Field Theory": introduction; renormalization; operator product expansions; and local field equations. The second volume contains lectures by Rudolf Haag on observables and fields, by Maurice Jacob on duality, by Michael Reed on non-Fock representations, and by Bruno Zumino on effective Lagrangians and broken symmetries.

Studies of High Temperature Superconductors, Volume 26 - Quaternary Borocarbides, Superconductors & Hg-Based High Tc Superconductors

The focus of this volume is the microstructures and related aspects of HTS and thus it forms the sequel (or the Part-II) to the earlier Volume 28 of the book series, which also had the microstructures as its mainstay. The chapters comprising the present volume bring out a host of fresh insights into the growth morphology, defect structures and the structure property relationships in various HTS systems. Closely related to the problem of microstructures is the important issue of the damage mechanics involved in the sample processing, which also forms one of the chapters of this volume. Given its interdisciplinary premise that 'Studies of High Temperature Superconductors: is aimed at professional scientists and engineers, as well as graduate students of physics, chemistry, materials science, solid state electronics and engineering'.

This book consists of over 600 selected descriptions and abstracts of books, book chapters, patents and journal articles from throughout the world dealing with this high-profile topic. Each citation contains complete bibliographic data plus key words. The entries are grouped under the headings of: Theory of Superconductivity; Superconducting Devices; Superconducting Properties of Materials; Applications of Superconductors: Author Index; Subject Index.

Translated from the Russian-language version published in 1988 (Nauka, Moscow), this volume is devoted to an investigation of the physical characteristics of a number of high-temperature superconducting compounds and to an investigation of the properties of certain electronic components based on the
