Download or read book Radioisotope Power Systems written by National Research Council and published by National Academies Press. This book was released on 2009-08-14 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft require electrical energy. This energy must be available in the outer reaches of the solar system where sunlight is very faint. It must be available through lunar nights that last for 14 days, through long periods of dark and cold at the higher latitudes on Mars, and in high-radiation fields such as those around Jupiter. Radioisotope power systems (RPSs) are the only available power source that can operate unconstrained in these environments for the long periods of time needed to accomplish many missions, and plutonium-238 (238Pu) is the only practical isotope for fueling them. Plutonium-238 does not occur in nature. The committee does not believe that there is any additional 238Pu (or any operational 238Pu production facilities) available anywhere in the world.The total amount of 238Pu available for NASA is fixed, and essentially all of it is already dedicated to support several pending missions-the Mars Science Laboratory, Discovery 12, the Outer Planets Flagship 1 (OPF 1), and (perhaps) a small number of additional missions with a very small demand for 238Pu. If the status quo persists, the United States will not be able to provide RPSs for any subsequent missions.

Book excerpt: "To commemorate the 50th anniversary of the first successful planetary mission, Mariner 2 sent to Venus in 1962, the NASA History Program Office, the Division of Space History at the National Air and Space Museum, NASA's Science Mission Directorate, and the Jet Propulsion Laboratory organized a symposium. "Solar System Exploration @ 50" was held in Washington, D.C., on 25-26 October 2012. The purpose of this symposium was to consider, over the more than 50-year history of the Space Age, what we have learned about the other bodies of the solar system and the processes by which we have learned it. Symposium organizers asked authors to address broad topics relating to the history of solar system exploration such as various flight projects, the development of space science disciplines, the relationship between robotic exploration and human spaceflight, the development of instruments and methodologies for scientific exploration, as well as the development of theories about planetary science, solar system origins and implications for other worlds. The papers in this volume provide a richly textured picture of important developments - and some colorful characters - in a half century of solar system exploration. A comprehensive history of the first 50 years of solar system exploration would fill many volumes. What readers will find in this volume is a collection of interesting stories about money, politics, human resources, commitment, competition and cooperation, and the "faster, better, cheaper" era of solar system exploration"--

Download or read book Ours to Explore written by Pippa Biddle and published by U of Nebraska Press. This book was released on 2021-06 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a 2014 essay that went viral, Pippa Biddle revealed the inequities and absurdities baked into voluntourism--the pairing of short-term, unskilled volunteer work with tourism. In the years since, Biddle has devoted herself to understanding the origins, intentions, and outcomes of a multibillion-dollar industry built on the premise of doing good, and she tracks that investigation in Ours to Explore. The flaws of voluntourism have included xenophobia, racism, paternalism, and a "West knows best" mentality. From exploitative orphanages that keep children in squalid conditions to attract donors to undertrained medical volunteers practicing their skills on patients in developing regions and to those looking for an inspiring selfie, Biddle reveals the hidden costs of the voluntourism complex. Along the way, readers meet inspiring activists and passionate community members, as well as thoughtful former voluntourists who still work to make a difference--just differently. Ours to Explore offers a plan for how the service-based travel industry can break the cycle of exploitation and suggests strategies for travelers who want to improve the places they visit for the long haul.

Book excerpt: Be energized, but not overwhelmed What’s the most pressure you’ve ever been under? How did you react? What helped? What didn’t? Over the past five years, Dane Jensen has asked these questions of thousands of high performers—from Olympic gold medalists to Navy SEALs, politicians, executives and busy parents. What has emerged from these conversations is that while everyone’s experiences under pressure are unique, pressure follows patterns and develops in predictable ways. If we can recognize the patterns, we can improve our ability to sidestep the biological traps that can sabotage us—and use the energy that accompanies pressure to thrive. The Power of Pressure combines the insights gathered from Jensen’s work with the latest research in biology and neuroscience to help you understand and use the “pressure equation” of importance, uncertainty and volume escape the traps of pressure with effective tools and tactics be ambidextrous so that you can handle pressure both in peak pressure moments and over the long haul reduce tension, sleep better and have more energy so that you can meet challenges head-on recognize pressure moments so that you can prepare for when you will likely the feel the heat leverage strategies so that you can give everything you’ve got when it’s most important And more! How we navigate our highest-pressure moments has a huge impact on the overall trajectory of our lives, both in terms of how successful we are and how much we enjoy the journey along the way.

Download or read book Enhancing the Resilience of the Nation s Electricity System written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-10-25 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.

Download or read book Relationship Rich Education written by Peter Felten and published by JHU Press. This book was released on 2020-11-03 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mentor, advisor, or even a friend? Making connections in college makes all the difference. What single factor makes for an excellent college education? As it turns out, it's pretty simple: human relationships. Decades of research demonstrate the transformative potential and the lasting legacies of a relationship-rich college experience. Critics suggest that to build connections with peers, faculty, staff, and other mentors is expensive and only an option at elite institutions where instructors have the luxury of time with students. But in this revelatory book brimming with the voices of students, faculty, and staff from across the country, Peter Felten and Leo M. Lambert argue that relationship-rich environments can and should exist for all students at all types of institutions. In Relationship-Rich Education, Felten and Lambert demonstrate that for relationships to be central in undergraduate education, colleges and universities do not require immense resources, privileged students, or specially qualified faculty and staff. All students learn best in an environment characterized by high expectation and high support, and all faculty and staff can learn to teach and work in ways that enable relationship-based education. Emphasizing the centrality of the classroom experience to fostering quality relationships, Felten and Lambert focus on students' influence in shaping the learning environment for their peers, as well as the key difference a single, well-timed conversation can make in a student's life. They also stress that relationship-rich education is particularly important for first-generation college students, who bring significant capacities to college but often face long-standing inequities and barriers to attaining their educational aspirations. Drawing on nearly 400 interviews with students, faculty, and staff at 29 higher education institutions across the country, Relationship-Rich Education provides readers with practical advice on how they can develop and sustain powerful relationship-based learning in their own contexts. Ultimately, the book is an invitation—and a challenge—for faculty, administrators, and student life staff to move relationships from the periphery to the center of undergraduate education.

Download or read book Solar Energy Conversion Systems written by Jeffrey R. S. Brownson and published by Academic Press. This book was released on 2013-11-09 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar energy conversion requires a different mind-set from traditional energy engineering in order to assess distribution, scales of use, systems design, predictive economic models for fluctuating solar resources, and planning to address transient cycles and social adoption. Solar Energy Conversion Systems examines solar energy conversion as an integrative design process, applying systems thinking methods to a solid knowledge base for creators of solar energy systems. This approach permits different levels of access for the emerging broad audience of scientists, engineers, architects, planners, and economists. Traditional texts in solar energy engineering have often emerged from mechanical or chemical engineering fields. Instead, Solar Energy Conversion Systems approaches solar energy conversion from the perspectives of integrative design, environmental technology, sustainability science, and materials science in the wake of amazing new thin films, polymers, and glasses developed by the optoelectronics and semiconductor industries. This is a new solar text for the new generation of green job designers and developers.

Download or read book Exploring and Shaping International Futures written by Barry B. Hughes and published by Routledge. This book was released on 2015-12-03 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: "People who run cities like to play Simcity to find out how impossible their jobs are. Hughes gives everyone a chance to play a kind of Simplanet, with outcomes far more complex and uncertain. In the process, the book and the computer program provide a coherent path to understanding an anarchic world." --Ronald A. Francisco, University of Kansas "What will be the future of human demographic, economic, environmental, and political-social systems throughout the 21st century? Where do current changes appear to be taking us? What kind of future would we prefer? How much leverage do we have to bring about the future we prefer? Do YOU share these interests of the book? If yes, you should study the book and learn how to cope with the future with the International Futures approach (IFs) developed by the authors. This large-scale integrated global simulation modeling system is a user-friendly, professional tool for long-term policy analysis and an educational tool in universities. I had a pleasure to learn it personally by cooperating with Barry Hughes." --Pentti Malaska, Professor of MS, DrTech, futurist Honorary member of the Club of Rome What will be the long-term impact of AIDS in Africa or concentration of global oil production in the Middle East? Exploring and Shaping International Futures helps readers understand such global trends in demographic, economic, energy, food, environmental, and socio-political systems. It allows businesspeople, government officials, and others to think concretely about global futures in each of these areas. It is the only book on the market that allows readers to use a computer simulation to track global trends and to develop alternative scenarios around those trends. It is one of relatively few books that really brings computer technology into the classroom, boardroom, or policy planning commission. The International Futures (IFs) computer simulation, around which the book is built, is now widely used in policy analysis as well as education. It has been instrumental in projects undertaken by such groups as the European Commission, the U.S. National Intelligence Council, and the United Nations. After three decades of development and refinement, the computer model is now easy to access and use. Readers can access the website with the IFs computer model at www.ifs.du.edu
