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

Aircraft Conceptual Design Synthesis means design by fitness-for-purpose. Design engineers can jump off from the point of given parameters and requirements – required performance, payloads and other factors. This is the first book for the aeronautical designer devoted to guiding the reader through this highly effective conceptual design synthesis process. This forms the procedure for the initial stage of the aircraft design process – the interpretation of a requirement into the preliminary layout. A logical design sequence is developed utilizing original modules to represent propulsion, lift, drag, mass, and performance. Aircraft Conceptual Design Synthesis includes a disk of spreadsheets that provides core data. Unlike existing approaches, the design synthesis method can be applied to novel aircraft concepts. CONTENTS INCLUDE The design process Aircraft configuration Flight regime and powerplant considerations Fuselage layout Configuration of the wing Basic lift, drag and mass representations Performance estimation Parametric analysis and optimisation Analysis of concept design “This is an important landmark book and in my view will become a standard by which others will be compared” – Dr E C P Ransom, Kingston University, UK

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.

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.

Aviation is one of the most widely talked about industries in the global economy and yet airlines continue to present an enigma. Between 2010 and 2018 the global airline industry experienced its longest period of sustained profitability; however, huge global profits hid a darker side. Many airlines made inadequate profits or serious losses while others collapsed entirely. This fifth edition of Flying Off Course explains why. Written by leading industry expert, Rigas Doganis, this book is an indispensable guide to the inner workings of this exciting industry. Providing a complete, practical introduction to the fundamentals of airline economics and marketing, it explores the structure of the market, the nature of airline costs, issues around pricing and demand, and the latest developments in e-commerce. Vibrant examples are drawn from passenger, charter and freight airlines to provide a dynamic view of the entire industry. This completely updated edition also explores the sweeping changes that have affected airlines in recent years. It includes much new material on airline alliances, long-haul low-cost airlines, new pricing policies and ancillary revenues in order to present a compelling account of the current state of the airline industry. Offering a practical approach and peppered with real examples, this book will be valuable to anyone new to the airline industry as well as those wishing to gain a wider insight into its operations and economics. For undergraduate or postgraduate students in transport studies, tourism and business the book provides a unique insider's view into the workings of this exciting industry.
