In a glorious exploration of the comics medium with echoes of 2001: A Space Odyssey, Flash Gordon, Chris Ware, and Moebius, a lone astronaut leaves a world ravaged by nuclear war in search of life. What she finds is beyond all explanation.

Zeolites have been the focus of intensive activity and growth in applications over the past 25 years in ion exchange, in adsorp tion and in catalytic process technology. Beginning with the syn thetic zeolites A,X and Y, continuing into the emerging ZSM series, and including selected natural zeolites, applications span the range from large-scale purification and separation to such major petroleum and petrochemical processes as catalytic cracking and aromatics alkylation. The future promises several new areas of signiciant use as our energy resource base is expanded. As a result, a NATO Advanced Study Institute on Zeolites was held in Alcabideche, Portugal, May 1-12, 1983. Its purpose was to summarize the state-of-the-art in zeolite science and technology, with particular emphasis on recent developments. This summary is intended to complement presentations of the latest research results at the 1983 International Zeolites Association meeting in .Reno, Nevada - USA. Both the fundamentals concepts and industrial applications are addressed in the lectures of the Institute. Individual chapters cover historical development, structure, crystallography and synthesis techniques. Basic principles of adsorption, diffusion, ion exchange and acidity are reviewed. A section on catalysis addresses shape selectivity, transition metals, bifunctional catalysis and "methanol to-gasoline". Included in the section on industrial applications are chapters on reactor and adsorber design, catalytic cracking, xylene and n -paraffins isomerization, as well as ion exchange and adsorption.

Hydrate research has expanded substantially over the past decade, resulting in more than 4,000 hydrate-related publications. Collating this vast amount of information into one source, Clathrate Hydrates of Natural Gases, Third Edition presents a thoroughly updated, authoritative, and comprehensive description of all major aspects of natural gas cla

Advances in Enzymology and Related Areas of Molecular Biology is a seminal series in the field of biochemistry, offering researchers access to authoritative reviews of the latest discoveries in all areas of enzymology and molecular biology. These landmark volumes date back to 1941, providing an unrivaled view of the historical development of enzymology. The series offers researchers the latest understanding of enzymes, their mechanisms, reactions and evolution, roles in complex biological process, and their application in both the laboratory and industry. Each volume in the series features contributions by leading pioneers and investigators in the field from around the world. All articles are carefully edited to ensure thoroughness, quality, and readability. With its wide range of topics and long historical pedigree, Advances in Enzymology and Related Areas of Molecular Biology can be used not only by students and researchers in molecular biology, biochemistry, and enzymology, but also by any scientist interested in the discovery of an enzyme, its properties, and its applications.

This filmography covers more than 300 horror films released from 1990 through 1999. The horror genre's trends and cliches are connected to social and cultural phenomena, such as Y2K fears and the Los Angeles riots. Popular films were about serial killers, aliens, conspiracies, and sinister "interlopers," new monsters who shambled their way into havoc. Each of the films is discussed at length with detailed credits and critical commentary. There are six appendices: 1990s cliches and conventions, 1990s hall of fame, memorable ad lines, movie references in Scream, 1990s horrors vs. The X-Files, and the decade's ten best. Fully indexed, 224 photographs.
