Book Description
When the Spanish colonized it in AD 1769, the California Coast was inhabited by speakers of no fewer than 16 distinct languages and an untold number of small, autonomous Native communities. These societies all survived by foraging, and ethnohistoric records show a wide range of adaptations emphasizing a host of different marine and terrestrial foods. Many groups exhibited signs of cultural complexity including sedentism, high population density, permanent social inequality, and sophisticated maritime technologies. The ethnographic era was preceded by an archaeological past that extends back to the terminal Pleistocene. Essays in this volume explore the last three and one half millennia of this long history, focusing on the archaeological signatures of emergent cultural complexity. Organized geographically, they provide an intricate mosaic of archaeological, historic, and ethnographic findings that illuminate cultural changes over time. To explain these Late Holocene cultural developments, the authors address issues ranging from culture history, paleoenvironments, settlement, subsistence, exchange, ritual, power, and division of labor, and employ both ecological and post-modern perspectives. Complex cultural expressions, most highly developed in the Santa Barbara Channel and the North Coast, are viewed alternatively as fairly recent and abrupt responses to environmental flux or the end-product of gradual progressions that began earlier in the Holocene.

Book Description
This textbook presents a concise comparison of catalytic and biocatalytic systems outlining their catalytic properties and peculiarities. Moreover, it presents a brief introduction to the science of catalysis and attempts to unify different catalytic systems into a single, conceptually coherent structure. In fact, molecular dynamics and complexity may occur in both catalysts and biocatalysts, with many similarities in both their structural configuration and operational mechanisms. Moreover, the interactions between the different components of the catalytic system that are important in defining the overall activity, including the nature of active sites are discussed. Each chapter includes end of chapter questions supported by an online instructor solution manual. This textbook will be useful for undergraduate and graduate chemistry and biochemistry students.

Book Description
Fritjof Capra, bestselling author of The Tao of Physics and The Web of Life, here explores another frontier in the human significance of scientific ideas—applying complexity theory to large-scale social interaction. In the 1980s, complexity theory emerged as a powerful alternative to classic, linear thought. A forerunner of that revolution, Fritjof Capra now continues to expand the scope of that theory by establishing a framework in which we can understand and solve some of the most important issues of our time. Capra posits that in order to sustain life, the principles underlying our social institutions must be consistent with the broader organization of nature. Discussing pertinent contemporary issues ranging from the controversial practices of the World Trade Organization (WTO) to the Human Genome Project, he concludes with an authoritative, often provocative plan for designing ecologically sustainable communities and technologies as alternatives to the current economic globalization.

Book Description
The progress in polymer science is revealed in the chapters of Polymer Science: A Comprehensive Reference, Ten Volume Set. In Volume 1, this is reflected in the improved understanding of the properties of polymers in solution, in bulk and in confined situations such as in thin films. Volume 2 addresses new characterization techniques, such as high resolution optical microscopy, scanning probe microscopy and other procedures for surface and interface characterization. Volume 3 presents the great progress achieved in precise synthetic polymerization techniques for vinyl monomers to control macromolecular architecture: the development of metallocene and post-metallocene catalysis for olefin polymerization, new ionic polymerization procedures, and atom transfer radical polymerization, nitroxide mediated polymerization, and reversible addition-fragmentation chain transfer systems as the most often used controlled/living radical polymerization methods. Volume 4 is devoted to kinetics, mechanisms and applications of ring opening polymerization of heterocyclic monomers and cycloolefins (ROMP), as well as to various less common polymerization techniques. Polycondensation and non-chain polymerizations, including dendrimer synthesis and various "click" procedures, are covered in Volume 5. Volume 6 focuses on several aspects of controlled macromolecular architectures and soft nano-objects including hybrids and bioconjugates. Many of the achievements would have not been possible without new characterization techniques like AFM that allowed direct imaging of single molecules and nano-objects with a precision available only recently. An entirely new aspect in polymer science is based on the combination of bottom-up methods such as polymer synthesis and molecularly programmed self-assembly with top-down structuring such as lithography and surface templating, as presented in Volume 7. It encompasses polymer and nanoparticle assembly in bulk and under confined conditions or influenced by an external field, including thin films, inorganic-organic hybrids, or nanofibers. Volume 8 expands these concepts focusing on applications in advanced technologies, e.g. in electronic industry and centers on combination with top down approach and functional properties like conductivity. Another type of functionality that is of rapidly increasing importance in polymer science is introduced in volume 9. It deals with various aspects of polymers in biology and medicine, including the response of living cells and tissue to the contact with biofunctional particles and surfaces. The last volume is devoted to the scope and potential provided by environmentally benign and green polymers, as well as energy-related polymers. They discuss new technologies needed for a sustainable economy in our world of limited resources. Provides broad and in-depth coverage of all aspects of polymer science from synthesis/polymerization, properties, and characterization methods and techniques to nanostructures, sustainability and energy, and biomedical uses of polymers Provides a definitive source for those entering or researching in this area by integrating the multidisciplinary aspects of the science into one unique, up-to-date reference work Electronic version has complete cross-referencing and multi-media components Volume editors are world experts in their field (including a Nobel Prize winner)

Book Description
The aim of this volume is to provide scientists with a comprehensive summary of new research areas in the activation of carbon monoxide, as one of the most reactive molecules, and in its applications. In order to understand the variety of the reactivity of CO, a quantum-chemical approach helps the reader to understand the binding state of CO to the solid surface (Chapter 1). The structure of the adsorbed CO can be better understood by examining its reactivity towards single crystals in the absence and in the presence of promoters (Chapter 2). The first approach in the reactivity study is that of studying catalytic activity of single crystals and structure sensitivity which are summarized in Chapter 3. One of the most prominent effects in the CO activation process is ascribed to the presence of additives, promoters which, in a real catalyst system, are far more complicated than on single crystal surfaces (Chapter 4). The original Fischer-Tropsch process applied fused iron or cobalt catalysts which were suitable for producing mainly straight chain hydrocarbons. The two most important processes involving CO activation, the new FT process and alcohol formation are discussed in Chapters 5 and 7. An important type of catalyst, the bimetallic catalysts, is discussed in Chapter 6. The role of hydrogen as one of the most frequently used partners in CO activation is discussed in Chapter 8. The field of production of specialty chemicals is an excellent example of the homogeneous catalytic activation of CO (Chapter 9). In Chapter 10 an overview is given of the industrial applications of CO chemistry and these are illustrated by working processes. The final chapter gives the reader some hints about future progress in the field.
