Mechanical Design In Organisms

This book deals with an interface between mechanical engineering and biology. Available for the first time in paperback, it reviews biological structural materials and systems and their mechanically important features and demonstrates that function at any particular level of biological integration is permitted and controlled by structure at lower levels of integration. Five chapters discuss the properties of materials in general and those of biomaterials in particular. The authors examine the design of skeletal elements and discuss animal and plant systems in terms of mechanical design. In a concluding chapter they investigate organisms in their environments and the insights gained from study of the mechanical aspects of their lives.

Mechanical Design of Structural Materials in Animals explores the principles underlying how molecules interact to produce the functional attributes of biological materials: their strength and stiffness, ability to absorb and store energy, and ability to resist the fatigue that accrues through a lifetime of physical insults. These attributes play a central role in determining the size and shape of animals, the ways in which they can move, and how they interact with their environment. By showing how structural materials have been designed by evolution, John Gosline sheds important light on how animals work. Gosline elucidates the pertinent theories for how molecules are arranged into macromolecular structures and how those structures are then built up into whole organisms. In particular, Gosline develops the theory of discontinuous, fiber-reinforced composites, which he employs in a grand synthesis to explain the properties of everything from the body wall of sea anemones to spiders' silks and insect cuticles, tendons, ligaments, and bones. Although the theories are examined in depth, Gosline's elegant discussion makes them accessible to anyone with an interest in the mechanics of life. Focusing on the materials from which animals are constructed, this book answers fundamental questions about mechanical properties in nature.

Understanding materials, their properties and behavior is fundamental to engineering design, and a key application of materials science. Written for all students of engineering, materials science and design, Materials Selection in Mechanical Design describes the procedures for material selection in mechanical design in order to ensure that the most suitable materials for a given application are identified from the full range of materials and section shapes available. Extensively revised for this fourth edition, Materials Selection in Mechanical Design is recognized as one of the leading materials selection texts, and provides a unique and genuinely innovative resource. Features new to this edition: Material property charts now in full color throughout Significant revisions of chapters on engineering materials, processes and process selection, and selection of material and shape while retaining the book's hallmark structure and subject content Fully revised chapters on hybrid materials and materials and the environment Appendix on data and information for engineering materials fully updated Revised and expanded end-of-chapter exercises and additional worked examples Materials are introduced through their properties; materials selection charts (also available on line) capture the important features of all materials, allowing rapid retrieval of information and application of selection techniques. Merit indices, combined with charts, allow optimization of the materials selection process. Sources of material property data are reviewed and approaches to their use are given. Material processing and its influence on the design are discussed. New chapters on environmental issues, industrial engineering and materials design are included, as are new worked examples, exercise materials and a separate, online Instructor's Manual. New case studies have been developed to further illustrate procedures and to add to the practical implementation of the text.

This volume explores questions about conceptual change from both scientific and philosophical viewpoints by analyzing the recent history of evolutionary developmental biology. It features revised papers that originated from the workshop "Conceptual Change in Biological Science: Evolutionary Developmental Biology, 1981-2011" held at the Max Planck Institute for the History of Science in Berlin in July 2010. The Preface has been written by Ron Amundson. In these papers, philosophers and biologists compare and contrast key concepts in evolutionary developmental biology and their development since the original, seminal Dahlem conference on evolution and development held in Berlin in 1981. Many of the original scientific participants from the 1981 conference are also contributors to this new volume and, in conjunction with other expert biologists and philosophers specializing on these topics, provide an authoritative, comprehensive view on the subject. Taken together, the papers supply novel perspectives on how and why the conceptual landscape has shifted and stabilized in particular ways, yielding insights into the dynamic epistemic changes that have occurred over the past three decades. This volume will appeal to philosophers of biology studying conceptual change, evolutionary developmental biologists focused on comprehending the genesis of their field and evaluating its future directions, and historians of biology examining this period when the intersection of ev olution and development rose again to prominence in biological science.

"This is the book I have been waiting for! Written by experts in each field, this Encyclopedia provides a wealth of information not only about the tidepool and shore life but also the oceanography associated with these habitats. This will be a major reference guide for years to come."--Dr. Nigella Hillgarth, Executive Director, Birch Aquarium at Scripps, Scripps Institution of Oceanography "The "Encyclopedia of Tidepools and Rocky Shores" covers much more than one might guess. It ranges from oceanography, to physiology, biomechanics, and conservation science, along with the expected treatment of the diverse groups of organisms that live in those habitats. The coverage of each topic is kept short and comprehensible to almost everyone, from high schools to colleges, and certainly to the general public interested in learning more about this fascinating part of our natural world. Best of all, the editors have managed to get some of the best scientists in the world, the absolute experts in their fields, to write the articles. The relatively short length of each entry also makes this book an ideal source for assigned readings to accompany marine biology, ecology, or oceanography classes, laboratories and field trips. It will be much appreciated by teachers and students."--Ken Sebens, Director of the Friday Harbor Marine Laboratories, University of Washington "The place where vast oceans meet the land is wondrous, complex and fascinating. Visitors from research scientists to toddlers have explored these ecosystems--one of nature's most popular theme parks. Anyone who has spent time amongst the sea stars, crabs and kelp departs full of unanswered questions. Now these questions can beanswered by dipping into the "Encyclopedia of Tidepools and Rocky Shores," The editors and contributors to this reference have created a new standard that will be an immediate classic."--Leon Panetta, Director, The Leon & Sylvia Panetta Institute for Public Policy "This volume is a wonderful introduction to the hidden and fascinating world of rocky tidepools. Grab a copy and head out with your kids or students for an outdoor experience that's sure to get them hooked. From remarkable adaptations of marine algae to weird animal life histories, tidepools hold amazing stories to tell. They deserve our interest--and our care--as part of earth's natural systems that sustain us all."--Julie Packard, Executive Director, Monterey Bay Aquarium "Tide pool lovers the world around will satisfy their curiosity, uncover new gems of insight and renew their wonder of nature at lands' end in this authoritative, fascinating and insightful compilation. Revealed within are the secrets of rocky shores and tide pools--that most dynamic of interfaces between the land and the sea, that treasure chest of rich biodiversity and keen insight, that world where science, literature, beauty and stewardship combine to form the now that integrates the past and tempts the future."--Jane Lubchenco, Wayne and Gladys Valley Professor of Marine Biology, Oregon State University

This book, originally published in French, examines the philosophical debates on functions over the last forty years and proposes new ways of analysis. Pervasive throughout the life sciences, the concept of function has the air of an epistemological scandal: ascribing a function to a biological structure or process amounts to suggesting that it is explained by its effects. This book confronts the debates on function with the use of the notion in a wide range of disciplines, such as biology, psychology, and medicine. It also raises the question of whether this notion, which is as old in the history of technology as it is in the life sciences, has the same meaning in these two domains.

Physical (Biological) Anthropology theme is a component of Encyclopedia Of Biological, Physiological And Health Sciences (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Biological anthropology, also known as physical anthropology, is a scientific discipline concerned with the biological and behavioral aspects of human beings, their related non-human primates and their extinct hominin ancestors. It is a subfield of anthropology that provides a biological perspective to the systematic study of human beings. This volume is aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.

This entertaining and informative book describes how living things bump up against non-biological reality. "My immodest aim," says the author, "is to change how you view your immediate surroundings." He asks us to wonder about the design of plants and animals around us: why a fish swims more rapidly than a duck can paddle, why healthy trees more commonly uproot than break, how a shark manages with such a flimsy skeleton, or how a mouse can easily survive a fall onto any surface from any height. The book will not only fascinate the general reader but will also serve as an introductory survey of biomechanics. On one hand, organisms cannot alter the earth's gravity, the properties of water, the compressibility of air, or the behavior of diffusing molecules. On the other, such physical factors form both constraints with which the evolutionary process must contend and opportunities upon which it might capitalize. Life's Devices includes examples from every major group of animals and plants, with references to recent work, with illustrative problems, and with suggestions of experiments that need only common household materials.
