Science in Flux: NASA's Nuclear Program at Plum Brook Station, 1955 - 2005 (NASA SP-2006-4317) - Nuclear Rockets, NERVA, Atomic Airplanes, Aircraft Nuclear Propulsion【電子書籍】[ Progressive Management ]

楽天Kobo電子書籍ストア
<p>This official NASA history document - converted for accurate flowing-text e-book format reproduction - is a dramatic account of the history of NASA's nuclear reactors at the Plum Brook Station in Sandusky, Ohio. The book details the origin of the facility and its work supporting efforts to build a nuclear-powered aircraft and nuclear rockets. The author describes the station as a "nuclear relic from NASA's golden age of space exploration."</p> <p>Testing and research reactors as scientific tools are more common than most people realize, and their history remains largely untold. There is an important distinction between these two types of reactors. A test reactor is one that operates above the 10-megawatt thermal power range, whereas a research reactor operates between 10 kilowatts and 10 megawatts. Power reactors that generate electricity (and operate at much higher power levels) frequently appear in newspaper headlines and are conspicuous because of their size and potential for disaster, whereas research reactors can be quietly tucked away, even located in the midst of a college campus. Since the completion of the first nuclear research reactor in 1942 at the University of Chicago, 672 facilities have been built throughout the world. The United States was the most prolific research reactor-building nation, with 227 sites, followed by the former Soviet Union with 97. These American reactors were constructed by national laboratories (Argonne, Oak Ridge, Brookhaven, and Los Alamos), universities (North Carolina State, Penn State, MIT, etc.), private industry (Westinghouse, General Electric, etc.), and the military. In 1961, the year that the Plum Brook reactor went "critical" (meaning that it was ready to conduct research with a sustained nuclear reaction), there were 120 nuclear research and test reactors in operation in the United States. At 60 megawatts of power, the Plum Brook facility (along with its 100-kilowatt mock-up research reactor) was the second most powerful test reactor in the country, at the time second only to the Engineering Test Reactor at the National Reactor Testing Station near Idaho Falls, Idaho. Worldwide, only the Soviet Union, Britain, and Canada possessed more powerful test reactors than Plum Brook before it went critical.</p> <p>In 1955 the National Advisory Committee for Aeronautics (NACA) began designing Plum Brook to help support the goal of a nuclear airplane with a nuclear test reactor to enable engineers to conduct materials testing. The advantages of having nuclear propulsion for an airplane were numerous. Most importantly, in an era before ICBMs and conventionally fueled planes that could circumnavigate the globe, a nuclear airplane promised the first chance for the American military to fly from the United States, drop bombs over the Soviet Union, and then return home. But technical and environmental problems overwhelmed the political and military potential of this program. Although John F. Kennedy helped to inspire the dream of nuclear rockets, ironically he also terminated the research program Plum Brook was originally intended to carry out. Kennedy suspended the nuclear airplane program in March 1961, after over $1 billion and 15 years of work. Less than 3 months before the reactor was to start operation, Plum Brook's main research program lost its political support. The public perceived nuclear airplanes as too costly and dangerous, and chemical fuels began providing many of the advantages once thought possible only with nuclear propulsion. This would be the first time that politics dramatically shaped the future of Plum Brook's scientific work. It would not be the last.</p> <p>Although the government had terminated the nuclear airplane program, Plum Brook and the research potential of its neutron flux still represented a valuable capability.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 1,135円

Condiciones objetivas y esperanzas subjetivas : movilidad social y marcos de (in)certidumbre : un abordaje multidimensional de las trayectorias de clase : Argentina durante la primera d?cada del siglo XXI【電子書籍】[ J?sica Lorena Pla ]

楽天Kobo電子書籍ストア
<p><em>Por Juan Cruz Medina. Periodista.</em> Cuando naci? el capitalismo, nacieron las clases sociales. Siglos despu?s, y a pesar de las m?ltiples discusiones por las cuales este concepto ha estado atravesado, esta caracter?stica sigue intacta y es vivida por los individuos como algo casi natural. Aunque tambi?n es vivida como natural la idea de que la sociedad de clases es una “sociedad m?vil”, y que cada persona puede, si as? lo desea y as? se lo propone, “llegar a donde lo desee”. Pero, ?qu? son las clases sociales? ?C?mo se forman? ?Qu? es la estratificaci?n social? ?Qu? es la movilidad social y qu? caracter?sticas toma? Y, principalmente, ?qu? argumentos utilizan las personas para explicar su posici?n (din?mica) de clase? En esta investigaci?n sociol?gica, J?sica Pla hace un repaso de los principales paradigmas que abordaron la tem?tica, desde Marx y Weber hasta los funcionalistas norteamericanos, y desarrolla una nueva perspectiva que combina distintas corrientes te?ricas para analizar el fen?meno. Desde esa mirada, y con un abordaje metodol?gico mixto, que entrelaza an?lisis de datos secundarios e historias de vida, Pla se aboca a estudiar las trayectorias de clase (concepto que sintetiza la relaci?n entre clases y movilidad social) durante los ?ltimos 20 a?os en la regi?n metropolitana de la Ciudad de Buenos Aires, dando lugar a los argumentos con los cuales los individuos justifican su lugar en la estructura de clases. De esta forma, pone en escena las contradicciones de esos argumentos y problematiza los conceptos de esfuerzo individual, recompensa y libertad de mercado. Se trata de un trabajo fundamental para comprender las condiciones sociales del comienzo del siglo XXI en la Regi?n Metropolitana de Buenos Aires, el rol del Estado como motor de las oportunidades de las personas, y el modo en el cual esas condiciones impactan en la subjetividad para pensar el presente individual y planear el futuro colectivo</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 377円

Exit, Voice and Loyalty in Asia Individual Choice under 32 Asian Societal Umbrellas【電子書籍】[ Takashi Inoguchi ]

楽天Kobo電子書籍ストア
<p>This book provides insightful observations and analyses of Asian citizens’ behaviour associated with requests to get a permit in conditions typically characterized by bureaucratic callousness. Using the AsiaBarometer Survey data on quality of life, it studies various types of behaviour using the multi-level regression models for 32 countries. In doing so, the book provides insights into how these societies cope with the state’s bureaucratism using Albert Hirschman’s concepts of Exit, Voice and Loyalty. Arguments are then juxtaposed with issues such as rampant corruption, government regulatory principles and measures, and calls by international organisations and non-governmental groups for business firms to be more strictly bound. Given the generally receding tide of democracy in Asian societies, this book will be of interest to academics, business, mass media and other professionals.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 10,938円

Ebenfalls beschreibe ich heute schon existente und sich m?glicherweise schon abzeichnende Trends im Agrarsektor. Die Bandbreite der wirtschaftlichen Aktivit?ten des prim?ren Sektors d?rfen heute nicht mehr nur auf die Erzeugung landwirtschaftlicher G?ter im engeren begrenzt werden. Vielmehr verlangt die Betrachtung auch ein Miteinbeziehen der Neben- Einnahmequellen der ?sterreichischen Landwirte. Dabei sind etwa Themengebiete wie die Energiegewinnung mittels Biomassenverbrennung oder Vergasung, die Versehung von Betriebsfl?chen mit Photovoltaikanlagen und der Handel mit Waren neu erschlossener wirtschaftlicher Bet?tigungsfelder wie z.B. Handel mit Holzpellets oder Hackschnitzelaufbereitung.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 1,373円

Platform Trial Designs in Drug Development Umbrella Trials and Basket Trials【電子書籍】

楽天Kobo電子書籍ストア
<p>Platform trials test multiple therapies in one indication, one therapy for multiple indications, or both. These novel clinical trial designs can dramatically increase the cost-effectiveness of drug development, leading to life-altering medicines for people suffering from serious illnesses, possibly at lower cost. Currently, the cost of drug development is unsustainable. Furthermore, there are particular problems in rare diseases and small biomarker defined subsets in oncology, where the required sample sizes for traditional clinical trial designs may not be feasible.</p> <p>The editors recruited the key innovators in this domain. The 20 articles discuss trial designs from perspectives as diverse as quantum computing, patient’s rights to information, and international health.</p> <p>The book begins with an overview of platform trials from multiple perspectives. It then describes impacts of platform trials on the pharmaceutical industry’s key stakeholders: patients, regulators, and payers. Next it provides advanced statistical methods that address multiple aspects of platform trials, before concluding with a pharmaceutical executive’s perspective on platform trials. Except for the statistical methods section, only a basic qualitative knowledge of clinical trials is needed to appreciate the important concepts and novel ideas presented.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 8,278円

Asia, the US and Extended Nuclear Deterrence Atomic Umbrellas in the Twenty-First Century【電子書籍】[ Andrew O'Neil ]

楽天Kobo電子書籍ストア
<p>Since the end of the Cold War, significant attention has focussed on the issue of nuclear deterrence and in particular whether formal nuclear security guarantees from nuclear weapons states to non-nuclear weapons states involving the possible use of nuclear weapons have a place in the twenty-first century global strategic landscape. Growing support for nuclear disarmament in the US and elsewhere has seen serious doubts being raised about the ongoing utility of extended nuclear deterrence.</p> <p>This book provides the first detailed analysis of the way in which extended nuclear deterrence operates in contemporary Asia. It addresses the following key questions: What does the role of extended nuclear deterrence in Asia tell us about the broader role of extended nuclear deterrence in the contemporary international system? Is this role likely to change significantly in the years ahead? O’Neil uses a theoretical and historical framework to analyse the contemporary and future dynamics of extended nuclear deterrence in Asia and challenges many of the existing orthodox perspectives on the topic.</p> <p>Providing a new perspective on debates surrounding extended nuclear deterrence, this book will be of interest not only to students and scholars of Asian politics, international relations and security studies, but also to policy makers and professionals.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 9,346円

Bones for Barnum Brown Adventures of a Dinosaur Hunter【電子書籍】[ Roland T. Bird ]

楽天Kobo電子書籍ストア
<p>Roland Thaxter Bird, universally and affectionately known to friends and associates as R. T., achieved a kind of Horatio Alger success in the scientific world of dinosaur studies. Forced to drop out of school at a young age by ill health, he was a cowboy who traveled from job to job by motorcycle until he met Barnum Brown, Curator of Vertebrae Paleontology at the American Museum of Natural History in New York and a leader in the study of dinosaurs. Beginning in 1934, Bird spent many years as an employee of the museum and as Brown's right-hand man in the field. His chart of the Howe Quarry in Wyoming, a massive sauropod boneyard, is one of the most complex paleontological charts ever produced and a work of art in its own right. His crowning achievement was the discovery, collection, and interpretation of gigantic Cretaceous dinosaur trackways along the Paluxy River near Glen Rose and at Bandera, Texas. A trackway from Glen Rose is on exhibit at the American Museum and at the Texas Memorial Museum in Austin. His interpretation of these trackways demonstrated that a large carnosaur had pursued and attacked a sauropod, that sauropods migrated in herds, and that, contrary to then-current belief, sauropods were able to support their own weight out of deep water. These behavioral interpretations anticipated later dinosaur studies by at least two decades.</p> <p>From his first meeting with Barnum Brown to his discoveries at Glen Rose and Bandera, this very human account tells the story of Bird's remarkable work on dinosaurs. In a vibrantly descriptive style, Bird recorded both the intensity and excitement of field work and the careful and painstaking detail of laboratory reconstruction. His memoir presents a vivid picture of camp life with Brown and the inner workings of the famous American Museum of Natural History, and it offers a new and humanizing account of Brown himself, one of the giants of his field.</p> <p>Bird's memoir has been supplemented with a clear and concise introduction to the field of dinosaur study and with generous illustrations which delineate the various types of dinosaurs.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 1,811円

Barnum Brown The Man Who Discovered Tyrannosaurus rex【電子書籍】[ Lowell Dingus ]

楽天Kobo電子書籍ストア
<p>From his stunning discovery of <em>Tyrannosaurus rex</em> one hundred years ago to the dozens of other important new dinosaur species he found, Barnum Brown led a remarkable life (1873?1963), spending most of it searching for fossilsーand sometimes oilーin every corner of the globe. One of the most famous scientists in the world during the middle of the twentieth century, Brownーwho lived fast, dressed to the nines, gambled, drank, smoked, and was known as a ladies’ manーbecame as legendary as the dinosaurs he uncovered. <em>Barnum Brown</em> brushes off the loose sediment to reveal the man behind the legend. Drawing on Brown’s field correspondence and unpublished notes, and on the writings of his daughter and his two wives, it discloses for the first time details about his life and travelsーfrom his youth on the western frontier to his spying for the U.S. government under cover of his expeditions. This absorbing biography also takes full measure of Brown’s extensive scientific accomplishments, making it the definitive account of the life and times of a singular man and a superlative fossil hunter.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 3,968円

Why Aren’t You Writing? Research, Real Talk, Strategies, & Shenanigans【電子書籍】[ Sharon K. Zumbrunn ]

楽天Kobo電子書籍ストア
<p>Write more with less pain! <em>Why Aren’t You Writing?: Research, Real Talk, Strategies, & Shenanigans</em> describes research on how bright and otherwise fairly normal people lose their minds when it comes to writing, and then shows the reader how to stop being one of those people. Author Sharon Zumbrunn designed this brief text for beginning and struggling academic writers so they can understand the psychological hang-ups that can get in the way of productivity.</p> <p>This book intertwines social and behavioral science research and humor to offer tips and exercises to help writers overcome their hurdles. Each chapter includes a description of findings from psychological and related research on writing hurdles and personal experiences of the writing process. Within the chapters, the author provides practical strategies and resources to help writers move beyond the challenges holding them back.</p> <p><em>Why Aren′t You Writing?</em> acknowledges how emotionally and mentally challenging it can be to be a "writer." This book helps readers to balance the hard work required for change with a bit of levity often necessary for withstanding sustained difficult thinking and meaningful change. Together, the components of this text present a systematic approach for beginning and struggling academics to become aware of what might be happening in their heads when they (don’t) write, and harness that knowledge to build a healthier and more resilient relationship with writing.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 4,085円

Conservation by Proxy Indicator, Umbrella, Keystone, Flagship, and Other Surrogate Species【電子書籍】[ Tim Caro ]

楽天Kobo電子書籍ストア
<p>The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health.</p> <p>Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book</p> <p>clarifies terminology and contrasts how different terms are used in the real world</p> <p>considers the ecological, taxonomic, and political underpinnings of these shortcuts</p> <p>identifies criteria that make for good surrogate species</p> <p>outlines the circumstances where the application of the surrogate species concept shows promise</p> <p>Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。 5,554円
