Radium and the Secret of Life

by Luis A. Campos

Before the hydrogen bomb indelibly associated radioactivity with death, many chemists, physicians, botanists, and geneticists believed that radium might hold the secret to life. Physicists and chemists early on described the wondrous new element in lifelike terms such as “decay” and “half-life,” and made frequent references to the “natural selection” and “evolution” of the elements. Meanwhile, biologists of the period used radium in experiments aimed at elucidating some of the most basic phenomena of life, including metabolism and mutation. From the creation of half-living microbes in the test tube to charting the earliest histories of genetic engineering, Radium and the Secret of Life highlights previously unknown interconnections between the history of the early radioactive sciences and the sciences of heredity. Equating the transmutation of radium with the biological transmutation of living species, biologists saw in metabolism and mutation properties that reminded them of the new element. These initially provocative metaphoric links between radium and life proved remarkably productive and ultimately led to key biological insights into the origin of life, the nature of heredity, and the structure of the gene. Radium and the Secret of Life recovers a forgotten history of the connections between radioactivity and the life sciences that existed long before the dawn of molecular biology.

Radon in Ground Water

by National Water Well Assoc.

This new book focuses on sampling and analysis, radon and radium in water supply wells, predictive models, geologic and hydrogeologic controls that influence radon occurrence, monitoring radon and other radioactivity from geologic sources and mining impacts on occurrence of radioactivity in ground water. Also discussed are occurrence, testing, treatment, and reduction of radon from groundwater. Because the most severe health hazard from indoor radioactivity results from inhalation of short-lived radioactive decay products of radon, the EPA scheduled a major conference early in 1987 on Radon, Radium, and Other Radioactivity in Ground Water-Hydrogeologic Impact and Application to Indoor Airborne Contamination. The result is this book.

Rail Crack Monitoring Using Acoustic Emission Technique (Springer Theses)

by Dan Li

This thesis provides an innovative strategy for rail crack monitoring using the acoustic emission (AE) technique. The field study presented is a significant improvement on laboratory studies in the literature in terms of complex rail profile and crack conditions as well as high operational noise. AE waves induced by crack propagation, crack closure, wheel-rail impact and operational noise were obtained through a series of laboratory and field tests, and analyzed by wavelet transform (WT) and synchrosqueezed wavelet transform (SWT). A wavelet power-based index and the enhanced SWT scalogram were sequentially proposed to classify AE waves induced by different mechanisms according to their energy distributions in the time–frequency domain. A novel crack sizing method taking advantage of crack closure-induced AE waves was developed based on fatigue tests in the laboratory. The propagation characteristics of AE waves in the rail were investigated, and Tsallis synchrosqueezed wavelet entropy (TSWE) with time was finally brought forward to detect and locate rail cracks in the field. The proposed strategy for detection, location and sizing of rail cracks helps to ensure the safe and smooth operation of the railway system. This thesis is of interest to graduate students, researchers and practitioners in the area of structural health monitoring.

Railways and Sustainable Low-Carbon Mobility in China

by Linna Li

This book explores the role of railways in developing sustainable low-carbon mobility by analyzing the intermodal relationship between railways and other transport modes. Focusing on geographical and governance perspectives, and taking China as a case study, it analyzes the competition and cooperation between and integration of railways and other transport modes, in order to provide guidance on future sustainable transport development. Firstly, the book examines the contribution of railways to low carbon emissions in China over recent decades by estimating the carbon dioxide emissions from various transport modes in China at national and regional levels using decomposition analysis. It then discusses the current competition and cooperation between railways and other transport modes, as well as their integration and the impact of their relationship on climate change. It also highlights how the competition between railways and other transport modes may change the passenger flows between city pairs and so alter transport carbon emissions and examines how cooperation and integration could improve passengers’ travel experience while at the same time reducing carbon emissions. Lastly, it addresses the implications for future sustainable transport development based on institutional analysis. Presenting multidisciplinary, sustainable transport research on the role of railways in reducing carbon emissions, and also offering policy recommendations for developing low-carbon, integrated transport in the future, this book is a valuable reference resource for graduates, researchers, and government managers responsible for transport development, urban planning and environmental policy.

Raimo Väyrynen: With a Foreword by Olli Rehn and a Preface by Allan Rosas (Pioneers in Arts, Humanities, Science, Engineering, Practice #28)

by Raimo Väyrynen

This book provides a broad overview of Professor Raimo Väyrynen’s academic work, his role in international research organizations, and his contributions to policy debates. It offers an interesting review of important political issues during the time span of half a century, from disarmament in Europe to the changing relationship between state sovereignty and transnational forces. Väyrynen has dealt with the changing agenda of peace and international relations, security and the arms race, and the world economy. This book provides comprehensive analyses of the regional and systemic structure of international relations, with the emphasis on conflicts and warfare between nations. It argues that while states, even smaller ones, still matter, transnational issues are increasingly important. Taking a historical perspective, the articles suggest that large-scale violence and arms races have been recurrent and cyclical phenomena in international relations. These events reflect the deep-seated inequalities in the political and economic systems which, moreover, vary considerably between regions. The publication is important reading for any researcher as well as students, policy-makers and the science-oriented public at large. • Traces the changing agenda of international relations from disarmament and the world economy to the changing relationship between state sovereignty and transnational forces. • Provides analyses of the regional and systemic structure in international relations, with the emphasis on conflicts and warfare. • Argues that large-scale violence and the arms race have been recurrent and cyclical phenomena in international relations. • Reviews important political issues from peace and conflict in Europe to the changing power relationship in the world.

Rain

by Cynthia Barnett

Rain is elemental, mysterious, precious, destructive. It is the subject of countless poems and paintings; the top of the weather report; the source of the world's water. Yet this is the first book to tell the story of rain. Cynthia Barnett's Rain begins four billion years ago with the torrents that filled the oceans, and builds to the storms of climate change. It weaves together science--the true shape of a raindrop, the mysteries of frog and fish rains--with the human story of our ambition to control rain, from ancient rain dances to the 2,203 miles of levees that attempt to straitjacket the Mississippi River. It offers a glimpse of our "founding forecaster," Thomas Jefferson, who measured every drizzle long before modern meteorology. Two centuries later, rainy skies would help inspire Morrissey's mopes and Kurt Cobain's grunge. Rain is also a travelogue, taking readers to Scotland to tell the surprising story of the mackintosh raincoat, and to India, where villagers extract the scent of rain from the monsoon-drenched earth and turn it into perfume. Now, after thousands of years spent praying for rain or worshiping it; burning witches at the stake to stop rain or sacrificing small children to bring it; mocking rain with irrigated agriculture and cities built in floodplains; even trying to blast rain out of the sky with mortars meant for war, humanity has finally managed to change the rain. Only not in ways we intended. As climate change upends rainfall patterns and unleashes increasingly severe storms and drought, Barnett shows rain to be a unifying force in a fractured world. Too much and not nearly enough, rain is a conversation we share, and this is a book for everyone who has ever experienced it.From the Hardcover edition.

Rainbow Dust: Three Centuries of Butterfly Delight

by Peter Marren

Like fluttering shards of stained glass, butterflies possess a unique power to pierce and stir the human soul. Indeed, the ancient Greeks explicitly equated the two in a single word, psyche, so that from early times butterflies were not only a form of life, but also an idea. Profound and deeply personal, written with both wisdom and wit, Peter Marren’s Rainbow Dust explores this idea of butterflies—the why behind the mysterious power of these insects we do not flee, but rather chase. At the age of five, Marren had his “Nabokov Moment,” catching his first butterfly and feeling the dust of its colored scales between his fingers. It was a moment that would launch a lifetime’s fascination rivaling that of the famed novelist—a fascination that put both in good company. From the butterfly collecting and rearing craze that consumed North America and Europe for more than two hundred years (a hobby that in some cases bordered on madness), to the potent allure of butterfly iconography in contemporary advertisements and their use in spearheading calls to conserve and restore habitats (even though butterflies are essentially economically worthless), Marren unveils the many ways in which butterflies inspire us as objects of beauty and as symbols both transient and transcendent. Floating around the globe and through the whole gamut of human thought, from art and literature to religion and science, Rainbow Dust is a cultural history rather than merely a natural one, a tribute to butterflies’ power to surprise, entertain, and obsess us. With a sway that far surpasses their fragile anatomy and gentle beat, butterfly wings draw us into the prismatic wonders of the natural world—and, in the words of Marren, these wonders take flight.

Rainfed Farming Systems

by Ian Partridge Philip Tow Colin Birch Ian Cooper

While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.

Rainwater Harvesting: In Urban Centers within the Hard Rock Terrain of the Deccan Basalts of India

by Anil Lalwani

Our dependency on groundwater resources and overuse thereof has led to a decline in water table so that in the last couple of decades the focus has shifted back to the traditional practices of rainwater harvesting, and ways and means have been sought to promote Rainwater harvesting in Urban areas to recharge the stressed groundwater systems. This book discusses in brief the classifications of Rainwater harvesting, and the various rainwater harvesting systems that are currently applied. The most important aspect for achieving any groundwater recharge is the availability of source water, this can be evaluated by analyzing the monsoon rainfall pattern, its frequency, number of rainy days, and maximum rainfall in a day and its variation in space and time. The Deccan basalts are one of the most enigmatic rocks in India and pose a very difficult task when it comes to ground water exploration and groundwater recharge, especially in the urban areas where due to constraint of space one needs to resort to borewells for recharge purpose. It is important for any such undertaking to understand the applicability and sustainability aspects of Rainwater harvesting as it is being practiced. This book tries to differentiate the Basaltic Aquifers from the other hard-rock Aquifers, and highlights the difficulties in trying to implement rainwater harvesting by groundwater recharge with the basaltic terrain. It also deals with the issue of long term sustainability of roof top Rainwater to meet the growing demands of fresh water. It also highlights some of the shortcomings in the methodologies used and the requirements for being considered in the various categories of green building rating agencies. It furthermore clarifies the possibility and limitations of dependence of roof top harvesting in addressing the question of water shortages, which is of common occurrence within most urban centres of India. It also helps in clarifying major misconceptions that are currently prevailing regarding Roof top Rainwater harvesting especially within the low capacity aquifers within the hard rock terrain of the Deccan basalts.
