Designing polymers and developing polymerization processes that are safe, prevent pollution, and are more efficient in the use of materials and engergy is an important topic in modern chemistry. Today, green polymer research can be seen increasingly in academia nd industry. It tackles all aspects of polymers and polymerization - everything from chemical feedstocks, synthetic pathways, and reaction media to the nature of the final polymer as related to its inherent nontoxicity or degradability. This book summarizes and evaluates the latest developments in green polymerization methods. Specifically, new catalytic methods and processes which incorporate renewable resources will be discussed by leading experts in the field of polymer chemistry. This book is a must-have for Polymer Chemists, Chemists Working with/on Organometallics, Biochemists, Physical Chemists, Chemical Engineers, Biotechnologists, Materials Scientists, and Catalytic Chemists.
Palliative Care is the first book to provide a comprehensive understanding of the new field that is transforming the way Americans deal with serious illness. Diane E. Meier, M.D., one of the field's leaders and a recipient of a MacArthur Foundation "genius award" in 2009, opens the volume with a sweeping overview of the field. In her essay, Dr. Meier examines the roots of palliative care, explores the key legal and ethical issues, discusses the development of palliative care, and presents ideas on policies that can improve access to palliative care. Dr. Meier's essay is followed by reprints of twenty-five of the most important articles in the field. They range from classic pieces by some of the field's pioneers, such as Eric Cassel, Balfour Mount, and Elizabeth Kübler-Ross, to influential newer articles on topics such as caregiving and cost savings of palliative care. The reprints cover a wide range of topics including: Why the care of the seriously ill is so important Efforts to cope with advanced illness Legal and ethical issues Pain management Cross-cultural issues Philosophical perspective The demand for palliative care has been nothing short of stunning-largely because of palliative care's positive impact on both the quality and the cost of care provided to seriously ill individuals. By providing a wide-ranging perspective on this growing field, this book will serve as a guide for developing meaningful approaches that will lead to better health care for all Americans.
The treatment of prostate cancer continues to be problematic owing to serious side-effects, including erectile dysfunction and urinary incontinence. Robotic radiosurgery offers a novel, rapid, non-invasive outpatient treatment option that combines robotics, advanced image-guided spatial positioning, and motion detection with submillimeter precision. This book examines all aspects of the treatment of prostate cancer with robotic radiosurgery. It explains how image-guided robotic radiosurgery overcomes the problem of patient motion during radiation therapy by continuously identifying the precise location of the prostate tumor throughout the course of treatment. Hypofractionated radiation delivery by means of robotic radiosurgery systems is also discussed in detail. The book closes by examining other emerging genitourinary applications of robotic radiosurgery. All of the authors are experts in their field who present a persuasive case for this fascinating technique.
