Liberating Energy from Carbon: Introduction to Decarbonization
by Nazim MuradovLiberating Energy from Carbon analyzes energy options in a carbon-constrained world. Major strategies and pathways to decarbonizing the carbon-intensive economy are laid out with a special emphasis on the prospects of achieving low-risk atmospheric CO2 levels. The opportunities and challenges in developing and bringing to market novel low and zero-carbon technologies are highlighted from technical, economic and environmental viewpoints. This book takes a unique approach by treating carbon in a holistic manner--tracking its complete transformation chain from fossil fuel sources to the unique properties of the CO2 molecule, to carbon capture and storage and finally, to CO2 industrial utilization and its conversion to value-added products and fuels. This concise but comprehensive sourcebook guides readers through recent scientific and technological developments as well as commercial projects that aim for the decarbonization of the fossil fuel-based economy and CO2 utilization that will play an increasingly important role in the near- and mid-term future. This book is intended for researchers, engineers, and students working and studying in practically all areas of energy technology and alternative energy sources and fuels.
Liberation Technology: Social Media and the Struggle for Democracy (A Journal of Democracy Book)
by Larry Diamond and Marc F. PlattnerThe revolutions sweeping the Middle East provide dramatic evidence of the role that technology plays in mobilizing citizen protest and upending seemingly invulnerable authoritarian regimes. A grainy cell phone video of a Tunisian street vendor’s self-immolation helped spark the massive protests that toppled longtime ruler Zine El Abidine Ben Ali, and Egypt’s "Facebook revolution" forced the ruling regime out of power and into exile. While such "liberation technology" has been instrumental in freeing Egypt and Tunisia, other cases—such as China and Iran—demonstrate that it can be deployed just as effectively by authoritarian regimes seeking to control the Internet, stifle protest, and target dissenters. This two-sided dynamic has set off an intense technological race between "netizens" demanding freedom and authoritarians determined to retain their grip on power.Liberation Technology brings together cutting-edge scholarship from scholars and practitioners at the forefront of this burgeoning field of study. An introductory section defines the debate with a foundational piece on liberation technology and is then followed by essays discussing the popular dichotomy of "liberation" versus "control" with regard to the Internet and the sociopolitical dimensions of such controls. Additional chapters delve into the cases of individual countries: China, Egypt, Iran, and Tunisia.This book also includes in-depth analysis of specific technologies such as Ushahidi—a platform developed to document human-rights abuses in the wake of Kenya’s 2007 elections—and alkasir—a tool that has been used widely throughout the Middle East to circumvent cyber-censorship.Liberation Technology will prove an essential resource for all students seeking to understand the intersection of information and communications technology and the global struggle for democracy.Contributors: Walid Al-Saqaf, Daniel Calingaert, Ronald Deibert, Larry Diamond, Elham Gheytanchi, Philip N.

Liberty Bell 7
by Colin BurgessNASA's Mercury astronauts were seven highly skilled professional test pilots. Each of them seemed to possess the strength of character and commitment necessary to overcome apparently insurmountable obstacles as the United States entered into a Cold War space race with the Soviet Union. This was never more evident than on the epic suborbital MR-4 flight of Liberty Bell 7 with astronaut Virgil ('Gus') Grissom piloting the spacecraft to a successful splashdown, followed by the premature blowing of the craft's explosive hatch. After a hurried exit and struggling to stay afloat, he could only watch helplessly as the recovery helicopter pilot valiantly fought a losing battle to save the sinking capsule. That day NASA not only lost a spacecraft but came perilously close to losing one of its Mercury astronauts, a decorated Korean fighter pilot from Indiana who might one day have soared to the highest goal of them all, as the first person to set foot on the Moon. For the first time, many of those closest to the flight of Liberty Bell 7 and astronaut Gus Grissom offer their stories and opinions on the dramatic events of July 21, 1961, and his later pioneering Gemini mission. They also tell of an often controversial life cut tragically and horrifically short in a launch pad fire that shocked the nation.

Life Atomic: A History of Radioisotopes in Science and Medicine (Synthesis Ser.)
by Angela N. CreagerAfter World War II, the US Atomic Energy Commission (AEC) began mass-producing radioisotopes, sending out nearly 64,000 shipments of radioactive materials to scientists and physicians by 1955. Even as the atomic bomb became the focus of Cold War anxiety, radioisotopes represented the government’s efforts to harness the power of the atom for peace—advancing medicine, domestic energy, and foreign relations. In Life Atomic, Angela N. H. Creager tells the story of how these radioisotopes, which were simultaneously scientific tools and political icons, transformed biomedicine and ecology. Government-produced radioisotopes provided physicians with new tools for diagnosis and therapy, specifically cancer therapy, and enabled biologists to trace molecular transformations. Yet the government’s attempt to present radioisotopes as marvelous dividends of the atomic age was undercut in the 1950s by the fallout debates, as scientists and citizens recognized the hazards of low-level radiation. Creager reveals that growing consciousness of the danger of radioactivity did not reduce the demand for radioisotopes at hospitals and laboratories, but it did change their popular representation from a therapeutic agent to an environmental poison. She then demonstrates how, by the late twentieth century, public fear of radioactivity overshadowed any appreciation of the positive consequences of the AEC’s provision of radioisotopes for research and medicine.

Life Cycle Assessment in the Built Environment
by Robert CrawfordLife cycle assessment enables the identification of a broad range of potential environmental impacts occurring across the entire life of a product, from its design through to its eventual disposal or reuse. The need for life cycle assessment to inform environmental design within the built environment is critical, due to the complex range of materials and processes required to construct and manage our buildings and infrastructure systems. After outlining the framework for life cycle assessment, this book uses a range of case studies to demonstrate the innovative input-output-based hybrid approach for compiling a life cycle inventory. This approach enables a comprehensive analysis of a broad range of resource requirements and environmental outputs so that the potential environmental impacts of a building or infrastructure system can be ascertained. These case studies cover a range of elements that are part of the built environment, including a residential building, a commercial office building and a wind turbine, as well as individual building components such as a residential-scale photovoltaic system. Comprehensively introducing and demonstrating the uses and benefits of life cycle assessment for built environment projects, this book will show you how to assess the environmental performance of your clients’ projects, to compare design options across their entire life and to identify opportunities for improving environmental performance.
