Aircraft emissions currently account for ~3.5% of all greenhouse gas emissions. The number of passenger miles has increased by 5% annually despite 9/11, two wars and gloomy economic conditions. Since aircraft have no viable alternative to the internal combustion engine, improvements in aircraft efficiency and alternative fuel development become essential. This book comprehensively covers the relevant issues in green aviation. Environmental impacts, technology advances, public policy and economics are intricately linked to the pace of development that will be realized in the coming decades. Experts from NASA, industry and academia review current technology development in green aviation that will carry the industry through 2025 and beyond. This includes increased efficiency through better propulsion systems, reduced drag airframes, advanced materials and operational changes. Clean combustion and emission control of noise, exhaust gases and particulates are also addressed through combustor design and the use of alternative fuels. Economic imperatives from aircraft lifetime and maintenance logistics dictate the drive for "drop-in" fuels, blending jet-grade and biofuel. New certification standards for alternative fuels are outlined. Life Cycle Assessments are used to evaluate worldwide biofuel approaches, highlighting that there is no single rational approach for sustainable buildup. In fact, unless local conditions are considered, the use of biofuels can create a net increase in environmental impact as a result of biofuel manufacturing processes. Governmental experts evaluate current and future regulations and their impact on green aviation. Sustainable approaches to biofuel development are discussed for locations around the globe, including the US, EU, Brazil, China and India.

Beloved, best-selling science writer Mary Roach’s “acutely entertaining, morbidly fascinating” (Susan Adams, Forbes) classic, now with a new epilogue. For two thousand years, cadavers – some willingly, some unwittingly – have been involved in science’s boldest strides and weirdest undertakings. They’ve tested France’s first guillotines, ridden the NASA Space Shuttle, been crucified in a Parisian laboratory to test the authenticity of the Shroud of Turin, and helped solve the mystery of TWA Flight 800. For every new surgical procedure, from heart transplants to gender confirmation surgery, cadavers have helped make history in their quiet way. “Delightful—though never disrespectful” (Les Simpson, Time Out New York), Stiff investigates the strange lives of our bodies postmortem and answers the question: What should we do after we die? “This quirky, funny read offers perspective and insight about life, death and the medical profession. . . . You can close this book with an appreciation of the miracle that the human body really is.” —Tara Parker-Pope, Wall Street Journal “Gross, educational, and unexpectedly sidesplitting.” —Entertainment Weekly

Carers are the bedrock of community care, and yet our understanding of how they do and do not fit into the care system is limited. Concern is often expressed about the need to support carers, but the best way to do this is not always clear. This book breaks new ground in exploring the reality of how service providers the doctors, social workers, and community nurses respond to carers. It looks at which carers get help and why, analyzing how age, relationship, class and gender structure the responses of service providers and carers. It examines the moral and policy issues posed by trying to incorporate carers' interests into service provision. What would services look like if they took the needs of carers seriously? How far can they afford to do so? Is this only achieved at the expense of disabled people? What is the proper relationship between carers and services? Carers pose in acute form many of the central dilemmas of social welfare, and the account presented here has the widest significance for the analysis of community care. Focusing on the views of carers as well as service providers, the book looks at caring across a variety of relationships and conditions, including people with mental health problems and learning disabilities.

Geared toward professional engineers, this volume will be helpful for students, too. Topics include methods of constructing static and dynamic equations, heated elastic solids, forms of aerodynamic operators, structural operators, and more. 1962 edition.

Empirical-statistical downscaling (ESD) is a method for estimating how local climatic variables are affected by large-scale climatic conditions. ESD has been applied to local climate/weather studies for years, but there are few ? if any ? textbooks on the subject. It is also anticipated that ESD will become more important and commonplace in the future, as anthropogenic global warming proceeds. Thus, a textbook on ESD will be important for next-generation climate scientists.
