Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

About ten years after the publication of the Second Edition (1973), it became apparent that it was time for an up-date of this book. This was especially true in this case, since the subject matter has traditionally dealt mainly with the structure, properties, and technology of the various elastomers used in industry, and these are bound to undergo significant changes over the period of a decade. In revising the contents of this volume, it was thought best to keep the orig inal format. Hence the first five chapters discuss the same general subject matter as before. The chapters dealing with natural rubber and the synthetic elastomers are up-dated, and an entirely new chapter has been added on the thermoplastic elastomers, which have, of course, grown tremendously in importance. Another innovation is the addition of a new chapter, "Miscellaneous Elastomers," to take care of "old" elastomers, e.g., polysulfides, which have decreased some what in importance, as well as to introduce some of the newly-developed syn thetic rubbers which have not yet reached high production levels. The editor wishes to express his sincere appreciation to all the contributors, without whose close cooperation this task would have been impossible. He would especially like to acknowledge the invaluable assistance of Dr. Howard Stephens in the planning of this book, and for his suggestion of suitable authors."

The world is experiencing an obesity epidemic. In both industrialized and emerging countries, the percentage of adults and children with obesity is increasing annually. It is no longer unusual to encounter a patient with extreme or morbid obesity in the operating room; these patients are routinely scheduled for every type of surgical procedure. Everyone involved in the peri-operative management of the surgical patient with morbid obesity - surgeons, anesthesiologists, internists, psychologists, nurses, nutritionists, respiratory therapists - must be aware of the special needs of these patients. Morbid Obesity: Peri-operative Management, 2nd edition considers the perioperative care of the morbidly obese patient, from preoperative preparation to intraoperative management and through to their postoperative course. Edited by leading experts in the management of the morbidly obese surgical patient, Morbid Obesity: Peri-operative Management, second edition, provides clear, practical clinical guidance on the management of the extremely obese surgical patient.

This book is the first to be devoted to the theory and applications of spherical (radial) basis functions (SBFs), which is rapidly emerging as one of the most promising techniques for solving problems where approximations are needed on the surface of a sphere. The aim of the book is to provide enough theoretical and practical details for the reader to be able to implement the SBF methods to solve real world problems. The authors stress the close connection between the theory of SBFs and that of the more well-known family of radial basis functions (RBFs), which are well-established tools for solving approximation theory problems on more general domains. The unique solvability of the SBF interpolation method for data fitting problems is established and an in-depth investigation of its accuracy is provided. Two chapters are devoted to partial differential equations (PDEs). One deals with the practical implementation of an SBF-based solution to an elliptic PDE and another which describes an SBF approach for solving a parabolic time-dependent PDE, complete with error analysis. The theory developed is illuminated with numerical experiments throughout. Spherical Radial Basis Functions, Theory and Applications will be of interest to graduate students and researchers in mathematics and related fields such as the geophysical sciences and statistics.

The dilemmas faced by disadvantaged college students seeking upward mobility and what educators can do to help these students flourish Upward mobility through higher education has been an article of faith for generations of working-class, low-income, and immigrant college students. While this path usually entails financial sacrifices and hard work, little attention has been paid to the personal compromises such students make as they enter worlds vastly different from their own. Measuring the true cost of higher education for those from disadvantaged backgrounds, Moving Up without Losing Your Way looks at the ethical dilemmas of upward mobility-the broken ties with family and friends, and the loss of community and identity-faced by students as they strive to earn a successful place in society. Drawing upon philosophy, social science, personal stories, and interviews, Jennifer Morton reframes the college experience, factoring in not just educational and career opportunities but also essential relationships. She urges educators to empower students with a new narrative, one that might allow them to achieve social mobility while retaining their best selves.

The fully updated 2nd edition of this textbook continues to serve as a comprehensive guide for information dealing with the ever-evolving field of bariatric surgery. The chapters are written by experts in the field and include the most up-to-date information, including new sections on quality in bariatric surgery, endoscopic surgery, and management of bariatric complications. This new edition continues to cover the basic considerations for bariatric surgery, the currently accepted procedures, outcomes of bariatric surgery including long-term weight loss, improvement and resolution of comorbidities, and improvement in quality of life. Other special emphasis is given to the topics of metabolic surgery and surgery for patients with lower BMI. In addition, new endoscopic bariatric procedures including the gastric balloons, endoscopic revisional procedures, and newer pharmacotherapy for obesity are reviewed.The ASMBS Textbook of Bariatric Surgery Second Edition will continue to be a leading source of scientific information for surgeons, physicians, residents, students, and integrated health members today and for years to come.

At the first and most basic level this work is a close reading of Herder's early essay "Uber den Fleiss in mehreren gelehrten Sprachen" (On Diligence in Several Learned Languages) of 1764.

Morton offers the first extended examination of Herder's distinctive philosophical and rhetorical idiom. He argues that Herder's often difficult style is not the mere hindrance to understanding it has often been taken to be, but rather that the substance of his thought is in fact integrally bound up with precisely how he constructs the texts intended to express it. The meaning of a Herderian text, Morton maintains, is conveyed both through the overt content of its propositions and, at the same time, through the various poetic techniques by which they are woven together. Interpretation of Herder's work thus depends on looking not only at what the words say (or appear to) but also, as with any literary text, at what they actually do--or, in the terms of the dialectic to which Morton refers throughout the book, at the gestural no less than the discursive dimension of the text.

Morton argues that the essay represents the essential key to the shape and direction of Herder's thought at large. In so doing, he provides a basis for a reassessment of Herder's position in intellectual and literary history generally, with particular reference to his role in the development of German Idealism, his key contribution to the foundations of Romanticism, and the impetus provided by his work to the rise of both linguistic and historicist paradigms of thought.

This work is of importance to scholars both in German studies and in other fields working with the eighteenth and early nineteenth centuries, as well as to all those concerned with modern intellectual history, philosophy of language, and philosophy of history.
