Internationally eminent scientists illuminate the most important scientific aspects of essential fatty acids (EFAs)-from their biochemistry to their physiological consequences in both health and illness. The distinguished contributors integrate a wide range of topics, including the basic biochemistry of EFAs and lipid metabolism, the role of EFAs in the neuronal membrane, the effects of EFAs and lipids in various diseases, and the effects of normal levels and EFA deficiencies on cognition and behavior. The book's consolidation of our knowledge of the biology and metabolism of the EFAs lays the groundwork for dramatic advances in our understanding of these ubiquitous biochemicals and their role in health and illness.
Written by the experts at Bird Watcher's Digest, Identify Yourself gives beginning and intermediate bird watchers a helping hand with some of the most confounding identification challenges -- birds that are commonly encountered but difficult to tell apart. Combining clear, easy-to-understand text with beautiful illustrations that show key field marks, Identify Yourself is the solution to identifying many of North America's hard-to-distinguish birds..
This edited collection examines the formation of urban networks and role of gateways in Europe from the Middle Ages to the modern world. In the past, gateway cities were merely perceived as transport points, only relevant to maritime shipping. Today they are seen as the organic entities coordinating the allocation of resources and supporting the growth, efficiency and sustainability of logistics (including both the transport and distribution of goods and services). Using different historical case studies, the authors consider how logistics shaped urban networks and were shaped by them.
This book looks at the persistence of life and how difficult it would be to annihilate life, especially a species as successful as humanity. The idea that life in general is fragile is challenged by the hardiness of microbes, which shows that astrobiology on exoplanets and other satellites must be robust and plentiful. Microbes have adapted to virtually every niche on the planet, from the deep, hot biosphere, to the frigid heights of the upper troposphere. Life, it seems, is almost indestructible. The chapters in this work examine the various scenarios that might lead to the extermination of life, and why they will almost always fail. Life's highly adaptive nature ensures that it will cling on no matter how difficult the circumstances. Scientists are increasingly probing and questioning life's true limits in, on and above the Earth, and how these limits could be pushed elsewhere in the universe. This investigation puts life in its true astronomical context, with the reader taken on a journey to illustrate life's potential and perseverance.
This edited volume provides an essential resource for urban morphology, the study of urban forms and structures, offering a much-needed mathematical perspective. Experts on a variety of mathematical modeling techniques provide new insights into specific aspects of the field, such as street networks, sustainability, and urban growth. The chapters collected here make a clear case for the importance of tools and methods to understand, model, and simulate the formation and evolution of cities. The chapters cover a wide variety of topics in urban morphology, and are conveniently organized by their mathematical principles. The first part covers fractals and focuses on how self-similar structures s...
This book uses 'politics of urban knowledge' as a lens to understand how professionals, administrations, scholars, and social movements have surveyed, evaluated and theorized the city, identified problems, and shaped and legitimized practical interventions in planning and administration. Urbanization has been accompanied, and partly shaped by, the formation of the city as a distinct domain of knowledge. This volume uses 'politics of urban knowledge' as a lens to develop a new perspective on urban history and urban planning history. Through case studies of mainly 19th and 20th century examples, the book demonstrates that urban knowledge is not simply a neutral means to represent cities as pre...
