Supercarbon
The information revolution of the twentieth century was brought about by microelectronics based on a simple and common material, silicon. Although silicon will continue to be of central importance in the next century, carbon, silicon's upstairs neighbor in the periodic table, will also be of great impor tance in future technology. Carbon has more flexible bonding and hence has various unique physical, chemical and biological properties. It has two types of bonding, sp3 and sp2, in diamond and graphite, respectively. The existence of the latter, "7r-electron bonding" , is responsible for carbon's versatile tal ents. Those materials having extended 7r-electron clouds are called '7r-electron ma...
Biomag 96
A modified Linear Estimation Approach was performed to reconstruct current sources within the heart. Based on MRI data sets the Boundary Element Method was used to create tailored multicompartment models of the human thorax which were used to solve the forward problem of magnetocardiography. The ability of the proposed method was demonstrated for the localization of a single current dipole as an example of a focal source. By means of introducing small shiftings to all reconstruction dipoles during linear estimation solution as well as performing a successive focussing strategy ignoring places without significant electrical activity the method could easily be extended to the reconstruction of real 3D sources. Based on a special minimum-norm solution the source volume can be estimated applying a finite element approximation using cube elements. The size of an extended current source can be estimated by superimposing the reconstructed dipoles to an equivalent dipole and comparing the corresponding volume with the sphere which would be related to the equivalent dipole. The deviation of these volumes can be taken as a criterion for non-dipolarity of sources.
High Performance Liquid Chromatography
High Performance Liquid Chromatography focuses on the developments, operating techniques, practices, equipment, and packing materials involved in High Performance Liquid Chromatography (HPLC). The book first offers information on basic chromatographic theory, equipment, and the column. Topics include resolution, efficiency, pumps and gradient systems, connectors, detectors, injectors, column packing and testing, packing materials, and coupling of columns. The text also ponders on sample treatment and separation methods, as well as trace analysis, reversed phase chromatography, and selection/optimization conditions. The publication examines adjustment of selectivity by the use of eluent additives and preparative liquid chromatography. Discussions focus on chromatography on dynamically modified oxide gels, metal complexation, crown ethers, ion pair chromatography, materials for preparative chromatography, and separation strategy. The text also reviews the trends in the practice of HPLC and chiral chromatography. The book is a dependable reference for readers interested in High Performance Liquid Chromatography.
The Alkaloids
This series is world-renowned as the leading compilation of current reviews of this vast field. Internationally acclaimed for more than forty years, The Alkaloids: Chemistry and Biology, founded by the late Professor R.H.F. Manske, continues to provide outstanding coverage of this rapidly expanding field. Each volume provides, through its distinguished authors, up-to-date and detailed coverage of particular classes or sources of alkaloids. Up-to-date reviews on a large and very important group of natural products from both a chemical and biological perspective Comprehensive dynamic reviews written by the leading authors in the respective fields Broader coverage than before on the biological aspects

New Horizons in Low-Dimensional Electron Systems
In Bird of Passage by Rudolf Peierls, we find a paragraph in which he de scribes his Cambridge days in the 1930s: On these [relativistic field theory] problems my main contacts were Dirac, and the younger theoreticians. These included in particular Nevill (now Sir Nevill) Mott, perhaps the friendliest among many kind and friendly people we met then. Professor Kamimura became associated with Sir Rudolf Peierls in the 1950s, when he translated, with his colleagues, Peierls's 1955 textbook, Quantum Theory of Solids, into Japanese. This edition, to which Sir Rudolf himself contributed a preface, benefitted early generations of Japanese solid state physicists. Later in 1974/5, during a sabbatical...
Textbook of Endodontology
The second edition of Textbook of Endodontology continues the aim of serving the educational needs of dental students and dental practitioners searching for updates on endodontic theories and techniques. Significantly restructured and completely updated, the new edition maintains the ethos of the original, facilitating ease of learning through pedagogical features such as annotated references, core concepts and key literature. It features a number of new chapters on topics ranging from outcomes of endodontic treatment to managing endodontic complications to dental trauma. Additionally, all other chapters have been thoroughly revised and brought up to date to reflect contemporary knowledge and practice. Textbook of Endodontology continues its important function of providing lucid scholarship and clear discussion of biological concepts and treatment principles in endodontics, and as such will be an important update to its current readers and a valuable discovery to its new audience.
Carbon Nanotubes
Carbon nanotubes have been studied extensively in relation to fullerenes, and together with fullerenes have opened a new science and technology field on nano scale materials. A whole range of issues from the preparation, structure, properties and observation of quantum effects in carbon nanotubes in comparison with 0-D fullerenes are discussed. In addition, complementary reviews on carbon nanoparticles such as carbon nano-capsules, onion-like graphite particles and metal-coated fullerenes are covered. This book aims to cover recent research and development in this area, and so provide a convenient reference tool for all researchers in this field. It is also hoped that this book can serve to stimulate future work on carbon nanotubes.
The Prokaryotes
The revised Third Edition of The Prokaryotes, acclaimed as a classic reference in the field, offers new and updated articles by experts from around the world on taxa of relevance to medicine, ecology and industry. Entries combine phylogenetic and systematic data with insights into genetics, physiology and application. Existing entries have been revised to incorporate rapid progress and technological innovation. The new edition improves on the lucid presentation, logical layout and abundance of illustrations that readers rely on, adding color illustration throughout. Expanded to seven volumes in its print form, the new edition adds a new, searchable online version.
