The impetus for this book came from the recent appearance of single specialty books pertaining to reoperative surgery on various organs in the pelvis, as well as from the recognition that several different disciplines are involved with the challenges of reoperative pelvic surgery. Surgeons often encounter challenging dilemmas involving organ systems that have historically been attended to by surgeonsrepresentingcloselyrelatedbut distinctspecialtyareas. Withincreasing sophisticationand knowledge about management of anatomically adjacent organs by the specialties of gynecologic oncology, gynecology, urology, and colon and rectal surgery, as well as the emergence of specialty training programs in urogynecology and pelvic floor disorders, we thought it appropriate and timely to create a textbook acknowledging this increasing knowledge and interspecialty collaboration. To this end,where appropriate, we haveincluded collaborative authors fromeach of the specialties, any ofwhommaybecalledupontoaddressaparticularanatomicarea.

With this in mind, the editors, from the fields of gynecologic oncology, urology, and colon and rectal surgery, identified experts in theirown fields who could bestcontribute to the management of specific problem areas. For example, since reoperations for endometriosis may involve uterus, adnexae, ovaries, or the colorectum, the chapter concerning this condition has been coauthored by specialists in colorectal surgery and gynecologic oncology. We have been fortunate to find experts who have collaborated to bring available evidence-based medicine, best demonstrated practices, and personal experience to their contributions.

The second edition of a widely used textbook that explores energy resource options and technologies with a view toward achieving sustainability on local, national, and global scales. Human survival depends on a continuing supply of energy, but the need for ever-increasing amounts of it poses a dilemma: How can we find energy sources that are sustainable and ways to convert and utilize energy that are more efficient? This widely used textbook is designed for advanced undergraduate and graduate students as well as others who have an interest in exploring energy resource options and technologies with a view toward achieving sustainability on local, national, and global scales. It clearly presents the tradeoffs and uncertainties inherent in evaluating and choosing sound energy portfolios and provides a framework for assessing policy solutions. The second edition examines the broader aspects of energy use, including resource estimation, environmental effects, and economic evaluations; reviews the main energy sources of today and tomorrow, from fossil fuels and nuclear power to biomass, hydropower, and solar energy; treats energy carriers and energy storage, transmission, and distribution; addresses end-use patterns in the transportation, industrial, and building sectors; and considers synergistic complex systems. This new edition also offers updated statistical data and references; a new chapter on the complex interactions among energy, water, and land use; expanded coverage of renewable energy; and new color illustrations. Sustainable Energy addresses the challenges of making responsible energy choices for a more sustainable future.
