Human Body Size And The Laws Of Scaling

by Thomas T. Samaras, Human Body Size And The Laws Of Scaling Books available in PDF, EPUB, Mobi Format. Download Human Body Size And The Laws Of Scaling books, Several books have been published on scaling in biology and its ramifications in the animal kingdom. However, none has specifically examined the multifaceted effects of how changes in human height create disproportionately larger changes in weight, surface area, strength and other physiological parameters. Yet, the impact of these non-linear effects on individual humans as well as our world's environment is enormous. Since increasing human body size has widespread ramifications, this book presents findings on the human species and its ecological niche. In biology, an ecological niche' refers to the role played by a species in its community and how the species interacts with its environment. Thus, a few chapters provide an ecological overview of how increasing human body size relates to human evolution, fitness, health, survival and the environment. This book provides a unique purview of the laws of scaling on human performance, health, longevity and the environment. Numerous examples from various research disciplines are used to illustrate the impact of increasing body size on many aspects of human enterprises, including work output, athletics and intellectual performance.

Download Human Body Size And The Laws Of Scaling books, This book is an exploration not only of the lessons that Abraham Lincoln, America's sixteenth president, drew from the founders of the United States, especially, George Washington and Thomas Jefferson, but also how others abroad have interpreted and incorporated his legacy. Because Lincoln occupied the presidency during democracy's first great civil war, he set a precedent for other leaders at home and abroad. "Liberal" leaders tend to identify with his roles as the Great Emancipator and magnanimous Great Reconciler, who eschewed "ethnic cleansing" in favour of restoring the Union as soon as possible after secession.

Scale

by Geoffrey West, Scale Books available in PDF, EPUB, Mobi Format. Download Scale books, "This is science writing as wonder and as inspiration." —The Wall Street Journal Wall Street Journal From one of the most influential scientists of our time, a dazzling exploration of the hidden laws that govern the life cycle of everything from plants and animals to the cities we live in. Visionary physicist Geoffrey West is a pioneer in the field of complexity science, the science of emergent systems and networks. The term “complexity” can be misleading, however, because what makes West’s discoveries so beautiful is that he has found an underlying simplicity that unites the seemingly complex and diverse phenomena of living systems, including our bodies, our cities and our businesses. Fascinated by aging and mortality, West applied the rigor of a physicist to the biological question of why we live as long as we do and no longer. The result was astonishing, and changed science: West found that despite the riotous diversity in mammals, they are all, to a large degree, scaled versions of each other. If you know the size of a mammal, you can use scaling laws to learn everything from how much food it eats per day, what its heart-rate is, how long it will take to mature, its lifespan, and so on. Furthermore, the efficiency of the mammal’s circulatory systems scales up precisely based on weight: if you compare a mouse, a human and an elephant on a logarithmic graph, you find with every doubling of average weight, a species gets 25% more efficient—and lives 25% longer. Fundamentally, he has proven, the issue has to do with the fractal geometry of the networks that supply energy and remove waste from the organism’s body. West’s work has been game-changing for biologists, but then he made the even bolder move of exploring his work’s applicability. Cities, too, are constellations of networks and laws of scalability relate with eerie precision to them. Recently, West has applied his revolutionary work to the business world. This investigation has led to powerful insights into why some companies thrive while others fail. The implications of these discoveries are far-reaching, and are just beginning to be explored. Scale is a thrilling scientific adventure story about the elemental natural laws that bind us together in simple but profound ways. Through the brilliant mind of Geoffrey West, we can envision how cities, companies and biological life alike are dancing to the same simple, powerful tune.

by Massimo Pigliucci, Phenotypic Integration Books available in PDF, EPUB, Mobi Format. Download Phenotypic Integration books, A new voice in the nature-nurture debate can be heard at the interface between evolution and development. Phenotypic integration--or, how large numbers of characteristics are related to make up the whole organism, and how these relationships evolve and change their function--is a major growth area in research, attracting the attention of evolutionary biologists, developmental biologists, and geneticists, as well as, more broadly, ecologists, physiologists, and paleontologists. This edited collection presents much of the best and most recent work the topic.

Metabolic Ecology

by Richard M. Sibly, Metabolic Ecology Books available in PDF, EPUB, Mobi Format. Download Metabolic Ecology books, One of the first textbooks in this emerging important field of ecology. Most of ecology is about metabolism: the ways that organisms use energy and materials. The energy requirements of individuals – their metabolic rates – vary predictably with their body size and temperature. Ecological interactions are exchanges of energy and materials between organisms and their environments. So metabolic rate affects ecological processes at all levels: individuals, populations, communities and ecosystems. Each chapter focuses on a different process, level of organization, or kind of organism. It lays a conceptual foundation and presents empirical examples. Together, the chapters provide an integrated framework that holds the promise for a unified theory of ecology. The book is intended to be accessible to upper-level undergraduate, and graduate students, but also of interest to senior scientists. Its easy-to-read chapters and clear illustrations can be used in lecture and seminar courses. Together they make for an authoritative treatment that will inspire future generations to study metabolic ecology.

Human Body Temperature

by Y. Houdas, Human Body Temperature Books available in PDF, EPUB, Mobi Format. Download Human Body Temperature books, The physiology of man is a complex subject. Unfortunately the regulation of temperature in the human body is not always well explained in textbooks. Many conference proceedings on the subject have been produced that give excellent detail on research topics. However, the subject matter is rarely presented as a composite whole. New technology has broadened the scope of methods available for studying body temperature. Thermography in particular has made it possible to record in real time the temperature distribution of large areas of the body surface. Modem image processing methods permit dynamic studies to be carried out and detailed analyses made retrospectively-a tremendous advance over the complex and slow techniques formerly used by physiologists. Yet although the associa tion between disease and temperature is as old as medicine itself, beyond the implicit faith in the clinical mercury thermometer, other measuring techniques are finding a slow acceptance. This book is designed to put into perspective the critical factors that make up "body temperature. " Body temperature cannot be viewed as a static entity but rather must be seen as a dynamic process. An understanding of this phenomenon is important to all who use thermal imaging and measuring techniques in clinical medi cine. These methods have, in recent years, brought engineers, physi cists, technicians, and clinicians together. Inevitably, however, there v vi Preface are gaps and overlaps in technology and understanding.
