This accessibly written book examines the most commonly taken dietary supplements, exploring what they are and what they're purported to do, and summarizing key research findings regarding their potential health benefits and risks. Today, more than 50 percent of Americans take at least one type of dietary supplement regularly. But do these products actually work? How are they regulated? Are there any potential health risks? Dietary Supplements: Fact versus Fiction examines the most commonly used non-nutrient supplements (those that are neither vitamins nor minerals and not essential for human health). Using a standardized structure, each entry discusses a particular supplement's origins, purported benefits, potential risks, and common dosage. Summaries of key research studies are included to help readers make informed decisions about supplements' usefulness. Introductory materials give readers a foundational understanding of how supplements are regulated and labeled and offer practical information about how to read a Supplement Facts panel. For those interested in supplements for a particular health complaint (such as fatigue or pain), a topic finder has also been included.
The aim of the volume is to provide an authoritative and international treatise bringing together current knowledge in the field of respiratory infection. The book will be organised by presentation rather than causative organism, a differentiating feature from the existing competition, and will be divided into four parts - 'General Issues', 'Community-acquired Infections', 'Nosocomial Infections' and 'Respiratory Infection in Immunocompromised Patients'. Each chapter will conclude with a summary highlighting practical 'take-home' messages regarding patient management for the reader. It will be highly illustrated, including colour plates where appropriate. The principal market will be pulmonologists with a specialist interest in this area and infectious disease specialists, but that the text will also be of interest to clinical researchers and a useful library reference.
State-of-the-technology tools for designing, optimizing, and manufacturing new materials Integrated computational materials engineering (ICME) uses computational materials science tools within a holistic system in order to accelerate materials development, improve design optimization, and unify design and manufacturing. Increasingly, ICME is the preferred paradigm for design, development, and manufacturing of structural products. Written by one of the world's leading ICME experts, this text delivers a comprehensive, practical introduction to the field, guiding readers through multiscale materials processing modeling and simulation with easy-to-follow explanations and examples. Following an introductory chapter exploring the core concepts and the various disciplines that have contributed to the development of ICME, the text covers the following important topics with their associated length scale bridging methodologies: Macroscale continuum internal state variable plasticity and damage theory and multistage fatigue Mesoscale analysis: continuum theory methods with discrete features and methods Discrete dislocation dynamics simulations Atomistic modeling methods Electronics structures calculations Next, the author provides three chapters dedicated to detailed case studies, including "From Atoms to Autos: A Redesign of a Cadillac Control Arm," that show how the principles and methods of ICME work in practice. The final chapter examines the future of ICME, forecasting the development of new materials and engineering structures with the help of a cyberinfrastructure that has been recently established. Integrated Computational Materials Engineering (ICME) for Metals is recommended for both students and professionals in engineering and materials science, providing them with new state-of-the-technology tools for selecting, designing, optimizing, and manufacturing new materials. Instructors who adopt this text for coursework can take advantage of PowerPoint lecture notes, a questions and solutions manual, and tutorials to guide students through the models and codes discussed in the text.
The availability of synchrotron x-ray sources and the subsequent developments described in this book have led to substantial progress in our understanding of molecular ordering at liquid interfaces. This practical guide enables graduate students and researchers working in physics, chemistry, biology and materials science to understand and carry out experimental investigations into the basic physical and chemical properties of liquid surfaces and interfaces. The book examines the surfaces of bulk liquids, thin wetting films and buried liquid-liquid interfaces. It discusses experiments on simple and complex fluids, including pure water and organic liquids, liquid crystals, liquid metals, electrified liquid-liquid interfaces and interfacial monolayers of amphiphiles, nanoparticles, polymers and biomolecules. A detailed description of the apparatus and techniques required for these experiments is provided, and theoretical approaches to data analysis are described, including approximate methods such as the Master formula, the Born approximation, Parratt's algorithm and the Distorted Wave Approximation.
This book, beautifully illustrated with specially commissioned photography, is a celebration of UCL's unique collections, with leading academics from the university invited to select and write about an object each found inspiring. From a jar of moles to an Egyptian unguent spoon, a finger X-ray to some prehistoric cereal grains, their choices were often surprising, their responses always fascinating.
Dred Scott and the Problem of Constitutional Evil , first published in 2006, concerns what is entailed by pledging allegiance to a constitutional text and tradition saturated with concessions to evil. The Constitution of the United States was originally understood as an effort to mediate controversies between persons who disputed fundamental values, and did not offer a vision of the good society. In order to form a 'more perfect union' with slaveholders, late-eighteenth-century citizens fashioned a constitution that plainly compelled some injustices and was silent or ambiguous on other questions of fundamental right. This constitutional relationship could survive only as long as a bisectional consensus was required to resolve all constitutional questions not settled in 1787. Dred Scott challenges persons committed to human freedom to determine whether antislavery northerners should have provided more accommodations for slavery than were constitutionally strictly necessary or risked the enormous destruction of life and property that preceded Lincoln's new birth of freedom.
Computational Materials Engineering is an advanced introduction to the computer-aided modeling of essential material properties and behavior, including the physical, thermal and chemical parameters, as well as the mathematical tools used to perform simulations. Its emphasis will be on crystalline materials, which includes all metals. The basis of Computational Materials Engineering allows scientists and engineers to create virtual simulations of material behavior and properties, to better understand how a particular material works and performs and then use that knowledge to design improvements for particular material applications. The text displays knowledge of software designers, materials scientists and engineers, and those involved in materials applications like mechanical engineers, civil engineers, electrical engineers, and chemical engineers. Readers from students to practicing engineers to materials research scientists will find in this book a single source of the major elements that make up contemporary computer modeling of materials characteristics and behavior. The reader will gain an understanding of the underlying statistical and analytical tools that are the basis for modeling complex material interactions, including an understanding of computational thermodynamics and molecular kinetics; as well as various modeling systems. Finally, the book will offer the reader a variety of algorithms to use in solving typical modeling problems so that the theory presented herein can be put to real-world use. - Balanced coverage of fundamentals of materials modeling, as well as more advanced aspects of modeling, such as modeling at all scales from the atomic to the molecular to the macro-material - Concise, yet rigorous mathematical coverage of such analytical tools as the Potts type Monte Carlo method, cellular automata, phase field, dislocation dynamics and Finite Element Analysis in statistical and analytical modeling

The New York Times bestselling author of Stuff Matters presents a rollicking guided tour of the secret lives of gases: the magnificent, strange, and fascinating substances that shape our world. Gases are all around us—they fill our lungs, power our movement, create stars, and warm our atmosphere. Often invisible and sometimes odorless, these ubiquitous substances are also the least understood materials in our world, and always have been. It wasn’t long ago that gases were seen as the work of ancient spirits: the sudden closing of a door after a change in airflow signaled a ghost’s presence. Scientists and engineers have struggled with their own gaseous demons. The development of high-pressure steam power in the eighteenth century literally blew away some researchers, ushering in a new era for both safety regulations and mass transit. And carbon dioxide, that noxious by-product of fossil fuel consumption and cow burps, gave rise to modern civilization. Its warming properties known for centuries, it now spells ruin for our fragile atmosphere. In It’s a Gas, bestselling materials scientist Mark Miodownik chronicles twelve gases and technologies that shaped human history. From hydrogen, carbon dioxide, and neon to laughing gas, steam, and even wind, the story of gases is the story of the space where science and belief collide, and of the elusive limits of human understanding.
Sometimes explosive, often delicious, occasionally poisonous, and always fascinating: the New York Times bestselling author of Stuff Matters offers an "entertaining discussion of the various ways our lives are enriched by fluids” (The Wall Street Journal). We know that we need water to survive, and that, for some of us, a cup of coffee or a glass of wine can feel just as vital. But do we really understand how much we rely on liquids, or their destructive power? Set on one of the author's transatlantic flights, Liquid Rules offers readers a tour of these formless substances, told through the language of molecules, droplets, heartbeats, and ocean waves. We encounter fluids within the plane—from hand soap to liquid crystal display screens—and without: in the volcanoes of Iceland, the frozen expanse of Greenland, and the marvelous California coastline. We come to see liquids with wonder and fascination, and to understand their potential for death and destruction. Just as in his bestselling, award-winning Stuff Matters, Mark Miodownik’s unique brand of scientific storytelling brings his subject to life in ways that will inform and amuse science buffs and lay readers alike.
