In Search of Mechanisms

Author: Carl F. Craver
Publisher: University of Chicago Press
ISBN: 022603982X
Category : Science
Languages : en
Pages : 251

Book Description
Neuroscientists investigate the mechanisms of spatial memory. Molecular biologists study the mechanisms of protein synthesis and the myriad mechanisms of gene regulation. Ecologists study nutrient cycling mechanisms and their devastating imbalances in estuaries such as the Chesapeake Bay. In fact, much of biology and its history involves biologists constructing, evaluating, and revising their understanding of mechanisms. With In Search of Mechanisms, Carl F. Craver and Lindley Darden offer both a descriptive and an instructional account of how biologists discover mechanisms. Drawing on examples from across the life sciences and through the centuries, Craver and Darden compile an impressive toolbox of strategies that biologists have used and will use again to reveal the mechanisms that produce, underlie, or maintain the phenomena characteristic of living things. They discuss the questions that figure in the search for mechanisms, characterizing the experimental, observational, and conceptual considerations used to answer them, all the while providing examples from the history of biology to highlight the kinds of evidence and reasoning strategies employed to assess mechanisms. At a deeper level, Craver and Darden pose a systematic view of what biology is, of how biology makes progress, of how biological discoveries are and might be made, and of why knowledge of biological mechanisms is important for the future of the human species.

Evaluating Evidence of Mechanisms in Medicine

Author: Veli-Pekka Parkkinen
Publisher: Springer
ISBN: 3319946102
Category : Medical
Languages : en
Pages : 131

Book Description
This book is open access under a CC BY license. This book is the first to develop explicit methods for evaluating evidence of mechanisms in the field of medicine. It explains why it can be important to make this evidence explicit, and describes how to take such evidence into account in the evidence appraisal process. In addition, it develops procedures for seeking evidence of mechanisms, for evaluating evidence of mechanisms, and for combining this evaluation with evidence of association in order to yield an overall assessment of effectiveness. Evidence-based medicine seeks to achieve improved health outcomes by making evidence explicit and by developing explicit methods for evaluating it. To date, evidence-based medicine has largely focused on evidence of association produced by clinical studies. As such, it has tended to overlook evidence of pathophysiological mechanisms and evidence of the mechanisms of action of interventions. The book offers a useful guide for all those whose work involves evaluating evidence in the health sciences, including those who need to determine the effectiveness of health interventions and those who need to ascertain the effects of environmental exposures.

A Brief Illustrated History of Machines and Mechanisms

Author: Emilio Bautista Paz
Publisher: Springer Science & Business Media
ISBN: 904812512X
Category : Technology & Engineering
Languages : en
Pages : 228

Book Description
Machines have always gone hand-in-hand with the cultural development of m- kind throughout time. A book on the history of machines is nothing more than a specific way of bringing light to human events as a whole in order to highlight some significant milestones in the progress of knowledge by a complementary persp- tive into a general historical overview. This book is the result of common efforts and interests by several scholars, teachers, and students on subjects that are connected with the theory of machines and mechanisms. In fact, in this book there is a certain teaching aim in addition to a general historical view that is more addressed to the achievements by “homo faber” than to those by “homo sapiens”, since the proposed history survey has been developed with an engineering approach. The brevity of the text added to the fact that the authors are probably not com- tent to tackle historical studies with the necessary rigor, means the content of the book is inevitably incomplete, but it nevertheless attempts to fulfil three basic aims: First, it is hoped that this book may provide a stimulus to promote interest in the study of technical history within a mechanical engineering context. Few are the co- tries where anything significant is done in this area, which means there is a general lack of knowledge of this common cultural heritage.

Mechanics of Mechanisms and Machines

Author: Ilie Talpasanu
Publisher: CRC Press
ISBN: 0429675712
Category : Technology & Engineering
Languages : en
Pages : 588

Book Description
Mechanics of Mechanisms and Machines provides a practical approach to machine statics, kinematics, and dynamics for undergraduate and graduate students and mechanical engineers. The text uses a novel method for computation of mechanism and robot joint positions, velocities, accelerations; and dynamics and statics using matrices, graphs, and generation of independent equations from a matroid form. The computational methods presented can be used for industrial and commercial robotics applications where accurate and quick mechanism/robot control is key. The book includes many examples of linkages, cams, and geared mechanisms, both planar and spatial types, having open or multiple cycles. Features • Presents real-world examples to help in the design process of planar and spatial mechanisms • Serves as a practical guide for the design of new products using mechanical motion analysis • Analyzes many applications for gear trains and auto transmissions, robotics and manipulation, and the emerging field of biomechanics • Presents novel matrix computational methods, ideal for the development of efficient computer implementations of algorithms for control or simulation of mechanical linkages, cams, and geared mechanisms • Includes mechanism animations and result data tables as well as comparisons between matrix-based equation results implemented using Engineering Equation Solver (EES) and results for the same mechanisms simulated using SolidWorks.

Mechanisms in Ancient Chinese Books with Illustrations

Author: Kuo-Hung Hsiao
Publisher: Springer Science & Business Media
ISBN: 3319020099
Category : Technology & Engineering
Languages : en
Pages : 310

Book Description
This book presents a unique approach for studying mechanisms and machines with drawings that were depicted unclearly in ancient Chinese books. The historical, cultural and technical backgrounds of the mechanisms are explained, and various mechanisms described and illustrated in ancient books are introduced. By utilizing the idea for the conceptual design of modern mechanisms, all feasible designs of ancient mechanisms with uncertain members and joints that meet the technical standards of the subjects’ time periods are synthesized systematically. Ancient Chinese crossbows (the original crossbow and repeating crossbows), textile mechanisms (silk-reeling mechanism, spinning mechanisms, and looms), and many other artisan's tool mechanisms are used as illustrated examples. Such an approach provides a logical method for the reconstruction designs of ancient mechanisms with uncertain structures. It also provides an innovative direction for researchers to further identify the original structures of mechanisms and machines with drawings in ancient literature. This book can be used as a textbook and/or supplemental reading material for courses related to history of ancient (Chinese) machinery and creative mechanism design for senior and graduate students.
