With the growing incidence of fragility fractures in Europe and North America over the last three decades, bone loss and osteoporosis have become active areas of research in skeletal biology. Bone loss is associated with aging in both sexes and is accelerated in women with the onset of menopause. However, bone loss is related to a suite of complex and often synergistically related factors including genetics, pathology, nutrition, mechani cal usage, and lifestyle. It is not surprising that its incidence and severity vary among populations. There has been increasing interest to investigate bone loss and osteoporosis from an anthropological perspective that utilizes a biocultural approach. Biocultural approaches recognize the inter-relationship between biological, cultural, and environmental variables. Anthropological studies also highlight the value of evolutionary and population approaches to the study of bone loss. These approaches are particularly suited to elucidate the multifactorial etiology of bone loss. The idea for this volume came out of a symposium organized by the editors at the 70th annual meeting of The American Association of Physical Anthropologists in Kansas City, Missouri. Many of the symposium participants, along with several additional leading scientists involved in bone and osteoporosis research, are brought together in this volume. Each chapter focuses on a different aspect of bone loss and fragility with a fresh and stimulating perspective.

Achieving a sustainable, reliable drinking water supply has emerged in recent years as an increasingly important goal, not only in the United States but also worldwide. This is being driven by population growth, increasing water demands, declining groundwater levels, contamination of water sources, greater awareness of adverse environmental impacts, concern regarding the potential impacts of global warming, and many other factors. Among the many methods that are being applied to achieve this goal, managed aquifer recharge is proving to be viable and cost-effective. Recent advances in the science of aquifer recharge, including the geochemistry, microbiology, and hydraulics, provide a strong foundation for the successful implementation of aquifer recharge projects. However, to achieve success, it is necessary to understand the lessons learned, taking advantage of good ideas that worked and not repeating the ideas that did not work. The overall goal of this project was to identify technical variables that result in successful design, operation, and maintenance of sustainable underground storage (SUS) facilities. The key objectives of the project were to increase the available knowledge base of SUS facilities throughout the United States, survey a variety underground storage facilities, identify and evaluate sites where SUS performance failed to meet objectives, address the use of SUS to reduce the vulnerability of water facilities, and create an easy-to-use, practical guidance document and outreach program to distribute research findings. The final report discusses surface and well recharge methods and includes a concise summary of the most important lessons learned from the 22 operating and failed recharge sites that were visited. It also includes a proposed analytical approach that may be applied for water utilities to reduce their vulnerability to service interruption and thereby enhance their system reliability. The appendix includes case studies for the 18 operating and four failed SUS facilities that were visited as part of this project. These are presented on a CD, providing useful perspectives regarding how different water utility systems have approached the need for SUS.

"The first architect-designed gas station - a Pittsburgh Gulf station in 1913 - was also the first to offer free road maps; the familiar Shell name and logo date from 1907, when a British mother-of-pearl importer expanded its line to include the newly discovered oil of the Dutch East Indies; the first enclosed gas stations were built only after the first enclosed cars made motoring a year-round activity - and operating a service station was no longer a "seasonal" job; the system of "octane" rating was introduced by Sun Oil as a marketing gimmick (74 for premium in 1931)." "As the number of "true" gas stations continues its steady decline - from 239,000 in 1969 to fewer than 100,000 today - the words and images of this book bear witness to an economic and cultural phenomenon that was perhaps more uniquely American than any other of this century."--Jacket.
