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.

The ethical and emotional tolls paid by disadvantaged college students seeking upward mobility and what educators can do to help these students flourish Upward mobility through the path of higher education has been an article of faith for generations of working-class, low-income, and immigrant college students. While we know this path usually entails financial sacrifices and hard work, very little attention has been paid to the deep personal compromises such students have to 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, the severed connections with former communities, and the loss of 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 with family, friends, and community. Finding that student strivers tend to give up the latter for the former, negating their sense of self, Morton seeks to reverse this course. She urges educators to empower students with a new narrative of upward mobility-one that honestly situates ethical costs in historical, social, and economic contexts and that allows students to make informed decisions for themselves. A powerful work with practical implications, Moving Up without Losing Your Way paves a hopeful road so that students might achieve social mobility while retaining their best selves.

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.
