NASA 50th Anniversary Proceedings: NASA's First 50 Years: Historical Perspectives


Book Description

On 29 July 1958, President Dwight D. Eisenhower signed the National Aeronautics and Space Act, creating the National Aeronautics and Space Administration (NASA), which became operational on 1 October of that year. Over the next 50 years, NASA achieved a set of spectacular feats, ranging from advancing the well-established field of aeronautics to pioneering the new fields of Earth and space science and human spaceflight. In the midst of the geopolitical context of the Cold War, 12 Americans walked on the Moon, arriving in peace “for all mankind.” Humans saw their home planet from a new perspective, with unforgettable Apollo images of Earthrise and the “Blue Marble,” as well as the “pale blue dot” from the edge of the solar system. A flotilla of spacecraft has studied Earth, while other spacecraft have probed the depths of the solar system and the universe beyond. In the 1980s, the evolution of aeronautics gave us the first winged human spacecraft, the Space Shuttle, and the International Space Station stands as a symbol of human cooperation in space as well as a possible way station to the stars. With the Apollo fire and two Space Shuttle accidents, NASA has also seen the depths of tragedy. In this volume, a wide array of scholars turn a critical eye toward NASA’s first 50 years, probing an institution widely seen as the premier agency for exploration in the world, carrying on a long tradition of exploration by the United States and the human species in general. Fifty years after its founding, NASA finds itself at a crossroads that historical perspectives can only help to illuminate.

Cerebral Blood Flow and Metabolism Measurement


Book Description

At the present time several techniques are available for studying quantitatively global and regional blood flow and metabolism of the human brain. How ever, many scientists working in the clinical and research field who would like to use these tools for their investigations may be less familiar with the indi cations and limitations of the individual methods. The rapid development of both modern imaging techniques and new tracers may have led to some con fusion in answering the question as to which method is appropriate to solve the diagnostic problem of an individuum with brain disease. Scepticism and ignorance as to the methods to be used as tools in differential diagnosis of brain disorders may have prevented their widespread introduction into clinical practice. Thus, the significance of circulatory and metabolic parameters involved in the majority of diseases of the central nervous system may have been overlooked. The contributions compiled in this book describe in detail the individual techniques, outline their indications and limitations and deal in particular with newer methods such as the atraumatic 133Xe technique, stable xenon tomogra phy, three-dimensional techniques such as 133Xe single photon emission tomog raphy and N-isopropyl-P23-iodoamphetamine. Positron emission tomography studies provide information on function and metabolism, particularly that of oxygen and glucose, in regional brain areas of interest. Nuclear magnetic reso nance may be a promising method for studying metabolic parameters; however, accurate circulation measurements can not be performed at present.




The Art of Communication


Book Description

Bring nuance, depth, and meaning to every conversation you have The Art of Communication is for anyone who senses that they could be communicating on a deeper level. Perhaps you are a confident communicator but suspect there may be more to the art of conversation that you have not yet been able to access. Or perhaps you feel that your conversations lack depth and meaning and that you'd like to enrich your relationships with others, if only you knew how. This book will address your concerns and show you how to engage wholeheartedly with others. There's more to conversation than just clear, rational thinking. Left-brain rationality is important, of course, but neuroscience increasingly shows that the right-brain skills of creativity, intuition and spontaneity are essential in good communication. In this guide, you'll discover ways of tapping into the full conversational potential that lies dormant within you, adding a level of nuance and watching the result as your relationships blossom. You may even find that untapped value in the form of new insights, ideas and creative thoughts, emerges from your daily conversations. Access the more nuanced arts of conversation to create strong connections and tangible results Build cross-disciplinary, cross-cultural connections to communicate effectively with people from different backgrounds Activate your whole mind — not just your intellect — to bring creativity and depth to communication Learn to be open-hearted, spontaneous, vulnerable, intuitive, and captivating in every conversation you hold From communication guru and bestselling author Judy Apps, The Art of Communication will show you how to breathe life into your relationships and produce powerful new thinking enabling you to transform the world you live in.




Principles of Air Quality Management


Book Description

Principles of Air Quality Management presents the fundamental principles that make up the broad field of air quality, pollution, and management. It is intended for those who have a general interest in the field, as well as those who have been involved in possibly only one or two of the specific aspects of air quality management. The book provides an understanding of the principles that govern our ability to manage air quality resources. It brings together in one volume current information on clean fuels, control technology, health effects, regulations, indoor air quality, global concerns, sources of criteria and hazardous air pollutants, atmospheric dispersion and modeling, air quality standards, risk assessments of air toxics, and trends. Beginning with the make-up of air and definitions of air and air pollution, this book outlines the history of air quality management, discussing emissions, standards, classifications of pollutants, and the production of secondary air pollution or photochemical smog.The discussion continues with the health effects of air pollutants and those that are considered toxic or hazardous, and the effects of those contaminants on the human body. Air pollutant damage to materials and vegetation, the standards of acceptable air quality from a health impacts outlook, and the techniques for measuring air quality are also reviewed. Air contaminant sources are approached from anthropogenic, geogenic, and biogenic viewpoints. From local, regional, and global perspectives, the book examines how contaminants are dispersed between sources and receptors. From these studies, an evaluation is made of the different models used to calculate dispersion and of the models used to predict ambient air quality. Federal laws and regulations, as well as regional perspectives, are summarized and evaluated. Control technologies available for both stationary sources and mobile sources are reviewed. From these sources, management options for limiting emissions and optimizing air pollutant strategies are analyzed. Also included is the latest data from the Auto/Oil Program on the impact of fuel reformulation on engine tailpipe emissions, the conclusions of the MECCA group on global warming, the findings of the California Healthy Building Pilot Study on indoor air quality, and the requirements for federal permits under the Clean Air Act Amendments. Global air quality concerns, relative global emissions, and alternative views are evaluated from a management options perspective. The book concludes with a presentation of indoor air quality and future trends in air quality management approaches, as well as their limitations.
