Book Description
Despite recent advances in important aspects of the lives of girls and women, pervasive challenges remain. These challenges reflect widespread deprivations and constraints and include epidemic levels of gender-based violence and discriminatory laws and norms that prevent women from owning property, being educated, and making meaningful decisions about their own lives--such as whether and when to marry or have children. These often violate their most basic rights and are magnified and multiplied by poverty and lack of education. This groundbreaking book distills vast data and hundreds of studies to shed new light on deprivations and constraints facing the voice and agency of women and girls worldwide, and on the associated costs for individuals, families, communities, and global development. The volume presents major new findings about the patterns of constraints and overlapping deprivations and focuses on several areas key to women s empowerment: freedom from violence, sexual and reproductive health and rights, ownership of land and housing, and voice and collective action. It highlights promising reforms and interventions from around the world and lays out an urgent agenda for governments, civil society, development agencies, and other stakeholders, including a call for greater investment in data and knowledge to benchmark progress.

Book Description
Guanidines, amidines and phosphazenes have been attracting attention in organic synthesis due to their potential functionality resulting from their extremely strong basicity. They are also promising catalysts because of their potential for easy molecular modification, possible recyclability, and reduced or zero toxicity. Importantly, these molecules can be derived as natural products – valuable as scientists move towards “sustainable chemistry”, where reagents and catalysts are derived from biomaterial sources. Superbases for Organic Synthesis is an essential guide to these important molecules for preparative organic synthesis. Topics covered include the following aspects: an introduction to organosuperbases physicochemical properties of organic superbases amidines and guanidines in organic synthesis phosphazene: preparation, reaction and catalytic role polymer-supported organosuperbases application of organosuperbases to total synthesis related organocatalysts: proton sponges and urea derivatives amidines and guanidines in natural products and medicines Superbases for Organic Synthesis is a comprehensive, authoritative and up-to-date guide to these important reagents for organic chemists, drug discovery researchers and those interested in the chemistry of natural products.

Book Description
A fresh examination of the past successes of natural products as medicines and their new future from both conventional and new technologies. High-performance liquid chromatography profiling, combinatorial synthesis, genomics, proteomics, DNA shuffling, bioinformatics, and genetic manipulation all now make it possible to rapidly evaluate the activities of extracts as well as purified components derived from microbes, plants, and marine organisms. The authors apply these methods to new natural product drug discoveries, to microbial diversity, to specific groups of products (Chinese herbal drugs, antitumor drugs from microbes and plants, terpenoids, and arsenic compounds), and to specific sources (the sea, rainforest, and endophytes). These new opportunities show how research and development trends in the pharmaceutical industry can advance to include both synthetic compounds and natural products, and how this paradigm shift can be more productive and efficacious.

Book Description
Today, Fuzzy Set Theory is the core discipline of so-called ‘soft’ computing, and provides new impetus for research in the field of artificial intelligence. In this fascinating book, the history of Fuzzy Set Theory and the ways it was first used are incorporated into the history of 20th century science and technology. Influences from philosophy, system theory and cybernetics stemming from the earliest part of the 20th century are considered alongside those of communication and control theory from mid-century.

Book Description
The Editors are sorry that the production of this volume was delayed by the ill health of one of them and we hope that this does not detract from the value of the con tents. For once this delay is not the fault of any of the authors only the editors are to blame. Many of the workers in the field of fibre toxicology became convinced by the middle 1980's that the worst of the furore over asbestos was over although we were left with an intriguing problem - how does asbestos cause disease? It was expected that the future impact of fibres on human health would be very small since asbestos exposure would be controlled and there was little chance that man-made fibres would prove haz ardous. These man-made fibres are much thicker than asbestos and, in most cases, they are less durable in the body. Both of these properties are believed to make them much less likely to cause disease. However many of us had fallen into the habit of calling these materials "asbestos substitutes" and thus they have acquired a little of the notoriety at tached to the natural fibrous minerals. Very few of these man-made fibres are actually used as replacements for asbestos. Asbestos was not suitable for the uses to which the insulation wools are usually put and the ceramic fibres are replacements for fire brick not asbestos which is destroyed at the temperatures at which these materials are used.

Book Description
The significance of food and feasting to Pre-Columbian Mesoamerican cultures has been extensively studied by archaeologists, anthropologists and art historians. Foodways studies have been critical to our understanding of early agriculture, political economies, and the domestication and management of plants and animals. Scholars from diverse fields have explored the symbolic complexity of food and its preparation, as well as the social importance of feasting in contemporary and historical societies. This book unites these disciplinary perspectives — from the social and biological sciences to art history and epigraphy — creating a work comprehensive in scope, which reveals our increasing understanding of the various roles of foods and cuisines in Mesoamerican cultures. The volume is organized thematically into three sections. Part 1 gives an overview of food and feasting practices as well as ancient economies in Mesoamerica. Part 2 details ethnographic, epigraphic and isotopic evidence of these practices. Finally, Part 3 presents the metaphoric value of food in Mesoamerican symbolism, ritual, and mythology. The resulting volume provides a thorough, interdisciplinary resource for understanding, food, feasting, and cultural practices in Mesoamerica.
