A Dirty Window: Diffuse and Translucent Molecular Gas in the Interstellar Medium (Astrophysics and Space Science Library #442)
by Loris Magnani Steven N. ShoreThis book provides an introduction to the physics of interstellar gas in the Galaxy. It deals with the diffuse interstellar medium which supplies a complex environment for exploring the neutral gas content of a galaxy like the Milky Way and the techniques necessary for studying this non-stellar component. After an initial exposition of the phases of the interstellar medium and the role of gas in a spiral galaxy, the authors discuss the transition from atomic to molecular gas. They then consider basic radiative transfer and molecular spectroscopy with particular emphasis on the molecules useful for studying low-density molecular gas. Observational techniques for investigating the gas and the dust component of the diffuse interstellar medium throughout the electromagnetic spectrum are explored emphasizing results from the recent Herschel and Planck missions. A brief exposition on dust in the diffuse interstellar medium is followed by a discussion of molecular clouds in general and high-latitude molecular clouds in particular. Ways of calibrating CO observations with the molecular hydrogen content of a cloud are examined along with the dark molecular gas controversy. High-latitude molecular clouds are considered in detail as vehicles for applying the techniques developed in the book. Given the transient nature of diffuse and translucent molecular clouds, the role of turbulence in the origin and dynamics of these objects is examined in some detail. The book is targeted at graduate students or postdocs who are entering the field of interstellar medium studies.
A Ditadura Militar e a Governança da Água no Brasil: Ideologia, Poderes Político-Econômico e Sociedade Civil na Construção das Hidrelétricas de Grande Porte (The Role of Ideology, Political-Economic Power and Civil Society in the Construction of Large Hydropower Dams) (IHE Delft PhD Thesis Series)
by Fernanda de Souza BragaIn recent decades there has been an exponential increase in large hydroelectric plants in Brazil, especially in the Amazon region. These large hydraulic structures impact the environment and the lives of people living in the places where they settle and require a special type of water governance. The dictatorial regime (1964-1985) created a "standard" for the construction of these great structures, through an institutional and legal framework, which benefited the Brazilian business elite but also, through the creation of a popular imagination, which shows itself lasting progress on the country's progress and development. The suspension of security, the fragility of institutional environmental structures, the disrespect for indigenous reserves, the lack of clarity about the concept of "affected population" and the non-payment of fair compensation were identified as one of the main challenges for a democratic water governance in the country. In the late 1970s, the Dam-Affected Movement (MAB) began its organization and is also studied in this research. The study is an important and insightful academic contribution to the understanding of the main bottlenecks of effective water governance in Brazil.

Each section is introduced by a commentary with further insights and thought-provoking questions on ideas raised in the chapters. The book also includes a 'Notes to Our Future Colleagues' section in each chapter, which presents readers with a collective vision for the state of science education research in the year 2050.
A Dog in the Cave: The Wolves Who Made Us Human
by Kay FrydenborgWe know dogs are our best animal friends, but have you ever thought about what that might mean? Fossils show we’ve shared our work and homes with dogs for tens of thousands of years. Now there’s growing evidence that we influenced dogs’ evolution—and they, in turn, changed ours. Even more than our closest relatives, the apes, dogs are the species with whom we communicate best. Combining history, paleontology, biology, and cutting-edge medical science, Kay Frydenborg paints a picture of how two different species became deeply entwined—and how we coevolved into the species we are today.

A Dog's World: Imagining the Lives of Dogs in a World without Humans
by Marc Bekoff Jessica PierceFrom two of the world’s leading authorities on dogs, an imaginative journey into a future of dogs without peopleWhat would happen to dogs if humans simply disappeared? Would dogs be able to survive on their own without us? A Dog’s World imagines a posthuman future for dogs, revealing how dogs would survive—and possibly even thrive—and explaining how this new and revolutionary perspective can guide how we interact with dogs now.Drawing on biology, ecology, and the latest findings on the lives and behavior of dogs and their wild relatives, Jessica Pierce and Marc Bekoff—two of today’s most innovative thinkers about dogs—explore who dogs might become without direct human intervention into breeding, arranged playdates at the dog park, regular feedings, and veterinary care. Pierce and Bekoff show how dogs are quick learners who are highly adaptable and opportunistic, and they offer compelling evidence that dogs already do survive on their own—and could do so in a world without us.Challenging the notion that dogs would be helpless without their human counterparts, A Dog’s World enables us to understand these independent and remarkably intelligent animals on their own terms.
A Dominant Character: The Radical Science And Restless Politics Of J. B. S. Haldane
by Samanth SubramanianA biography of J. B. S. Haldane, the brilliant and eccentric British scientist whose innovative predictions inspired Aldous Huxley’s Brave New World. J. B. S. Haldane’s life was rich and strange, never short on genius or drama—from his boyhood apprenticeship to his scientist father, who first instilled in him a devotion to the scientific method; to his time in the trenches during the First World War, where he wrote his first scientific paper; to his numerous experiments on himself, including inhaling dangerous levels of carbon dioxide and drinking hydrochloric acid; to his clandestine research for the British Admiralty during the Second World War. He is best remembered as a geneticist who revolutionized our understanding of evolution, but his peers hailed him as a polymath. One student called him “the last man who might know all there was to be known.” He foresaw in vitro fertilization, peak oil, and the hydrogen fuel cell, and his contributions ranged over physiology, genetics, evolutionary biology, mathematics, and biostatistics. He was also a staunch Communist, which led him to Spain during the Civil War and sparked suspicions that he was spying for the Soviets. He wrote copiously on science and politics in newspapers and magazines, and he gave speeches in town halls and on the radio—all of which made him, in his day, as famous in Britain as Einstein. It is the duty of scientists to think politically, Haldane believed, and he sought not simply to tell his readers what to think but to show them how to think. Beautifully written and richly detailed, Samanth Subramanian’s A Dominant Character recounts Haldane’s boisterous life and examines the questions he raised about the intersections of genetics and politics—questions that resonate even more urgently today.
A Dominant Character: The Science and Politics of J.B.S. Haldane
by Samanth SubramanianJ.B.S. Haldane, scientist extraordinaire—born in Britain yet spiritually bound to India—remains one of the most enigmatic geniuses of the modern era. Here is a man who saw action in two world wars, engaged in the most radical politics of his day, conducted groundbreaking scientific research, and wrote with flair and conviction—yet Haldane&’s universe remains shrouded in mystery. <P><P>Award-winning author Samanth Subramanian’s latest offering undoes this travesty. Besides shedding light on Haldane’s contributions to genetics and evolutionary biology—he was the first to calculate the rate at which mutations occur and accumulate in genes—the book illuminates Haldane&’s inner world—his towering intellect, his radical vision of society, his provocative philosophy, and his attempts a wrestling with the essential moral questions that scientific progress must raise. <P><P>Equally, the book dwells on Haldane’s years in India—his journey to the nation; his affiliation with the Indian Statistical Institute, Calcutta; his attachment to the Genetics and Biometry Laboratory in Bhubaneshwar (where he died). Dronamraju’s description of Haldane as ‘the last man who knew everything’ was, at its simplest, an acknowledgement of his command over multiple subjects. But it was also an astute observation that Haldane’s era was the last time when the realms of scientific knowledge were limited enough for a single person to apprehend in near-entirety. To know everything was to see the forces of the world unified and to conceive of life in its full complexity. A Dominant Character will give readers a taste of that heady sensation.

A Dream of Flight: Alberto Santos-Dumont's Race Around the Eiffel Tower
by Rob Polivka Jef PolivkaDebut nonfiction duo Rob and Jef Polivka offer an illustrated madcap adventure in A Dream of Flight, a dynamic biography of Alberto Santos-Dumont, an inventor who risked everything to reach the skies. And sure enough, his successes and failures brought the world’s people closer together.Ready? Set. Fly! At the turn of the twentieth century, no aviation prize was more coveted in Europe than the Deutsch Prize. To win it, a pilot would have to fly a balloon from Paris’s Aero Club around the Eiffel Tower and back in thirty minutes or less. Who would be the first to succeed?Alberto Santos-Dumont thought he could. His latest design, Airship No. 6, was perfected from the countless lessons he learned during previous crashes. On the morning of October 19, 1901, Santos was making good time in the race when disaster struck—his motor had sputtered to a stop mid-air! Would Santos make it to the finish line in time—let alone survive?
A Dynamical Perspective on the ɸ4 Model: Past, Present and Future (Nonlinear Systems and Complexity #26)
by Jesús Cuevas-Maraver Panayotis G. KevrekidisThis book presents a careful selection of the most important developments of the \phi^4 model, offering a judicious summary of this model with a view to future prospects and the challenges ahead. Over the past four decades, the \phi^4 model has been the basis for a broad array of developments in the physics and mathematics of nonlinear waves. From kinks to breathers, from continuum media to discrete lattices, from collisions of solitary waves to spectral properties, and from deterministic to stochastic models of \phi^4 (and \phi^6, \phi^8, \phi^12 variants more recently), this dynamical model has served as an excellent test bed for formulating and testing the ideas of nonlinear science and solitary waves.
A Face in the Rock: The Tale Of A Grand Island Chippewa
by Loren R. Graham Abigail RorerEight miles long and four miles wide, Grand Island lies off the south shore of Lake Superior. It was once home to a sizable community of Chippewa Indians who lived in harmony with the land and with each other. Their tragic demise began early in the nineteenth century when their fellow tribesmen from the mainland goaded them into waging war against rival Sioux. The war party was decimated; only one young brave, Powers of the Air, lived to tell the story that celebrated the heroism of his band and formed the basis of the legend that survives today. Distinguished historian Loren R. Graham has spent more than forty years researching and reconstructing the poignant tale of Powers of the Air and his people. A Face in the Rock is an artful melding of human history and natural history; it is a fascinating narrative of the intimate relation between place and people. Powers of the Air lived to witness the desecration of Grand Island by the fur and logging industries, the Christianization of the tribe, and the near total loss of the Chippewa language, history, and culture. Graham charts the plight of the Chippewa as white culture steadily encroaches, forcing the native people off the island and dispersing their community on the mainland. The story ends with happier events of the past two decades, including the protection of Grand Island within the National Forest system, and the resurgence of Chippewa culture.

A Far-Infrared Spectro-Spatial Space Interferometer: Instrument Simulator and Testbed Implementation (Springer Theses)
by Roser Juanola-ParramonThis thesis describes the physics and computational aspects of an end-to-end simulator to predict the performance of a Space-based Far Infrared Interferometer. The present thesis also includes, the science capabilities and instrumental state-of-the art. The latter is the ambitious next step which the Far-Infrared Astrophysical community needs to take to improve in anyway on the results of the most recent and current space telescopes in this wavelength region. This thesis outlines the requirements involved in such a mission and describes the most promising technique to capture most of the astrophysical information by combining spectroscopy to spatial interferometer. The simulation of such a system is extremely complex requiring multiple Fourier transforms each of which is subject to instrument non-idealities and appropriate optimization techniques. As a conclusion, the thesis provides an example of the basic performance achievable with such an instrument when targeting a young star formation region.

A Few Tens au Scale Physical and Chemical Structures Around Young Low-Mass Protostars (Springer Theses)
by Yoko OyaThis book characterizes the kinematic and chemical structures of disk-forming regions around low-mass protostellar sources and their interplay based on Atacama Large Millimeter/submillimeter Array (ALMA) observations. It describes the chemical evolution of molecules formed in an interstellar gas using the ALMA observations of 5 Sun-like protostars at a spatial resolution of a few tens au scale, which unveils the physical mechanism of star and planetary formation. The book reviews the author’s successful works, focusing on two key findings: (i) A drastic change in the chemical composition of the gas around the centrifugal barrier of the infalling-rotating envelopes, and (ii) the chemical composition in the disk-forming regions, which varies from source to source depending on the chemical characteristics of the parent molecular cloud. These findings are based on the fine characterization of physical structures based on careful kinematic analyses. An additional attraction is the inclusion of the skillful reviews of ALMA observatory and its observation and physical models to describe the observed gas structure.

A Field Guide to Climate Change: Understanding the Problems
by Adam BriggleThis book is a guide for understanding climate change. It takes an interdisciplinary approach because climate change is simultaneously a matter of science, engineering, economics, politics, culture, ethics, and more. A Field Guide to Climate Change thus follows the contours of climate change as it appears in the world—as a tangle of problems. Briggle presents climate literacy as a form of problem-posing by offering a set of tools for understanding how problems get framed, debated, and resolved. Through developing climate literacy, students gain the ability to think critically about how facts are constructed and mobilized in the pursuit of values. <P><P> Part One (Big Picture and Fundamentals) provides basic definitions and broad orientation by situating climate change within larger contexts like the Anthropocene, international climate diplomacy, sustainable development, and “green growth.” Part Two (Climate Sciences) offers tools for understanding climate science, its historical development, and its place in society by asking: who knows, what do we know, and how do we know it? Part Three (Politics, Ethics, and Policy) shows how to analyze debates about climate change policies from mitigation to rewilding.

A Field Guide to Germs (Newly Revised and Updated): Revised and Updated
by Wayne BiddleFrom the ravages of the Ebola virus in Zaire to outbreaks of pneumonic plague in India and drug-resistant TB in New York City, contagious diseases are fighting back against once-unconquerable modern medicine. Public concern about infectious disease is on the rise as newspapers trumpet the arrivals of new germs and the reemergence of old ones. In A Field Guide to Germs, Pulitzer Prize-winning science writer Wayne Biddle brings readers face to face with nearly one hundred of the best-known (in terms of prevalence, power, historical importance, or even literary interest) of the myriad pathogens that live in and around the human population. Along with physical descriptions of the organisms and the afflictions they cause, the author provides folklore, philosophy, history, and such illustrations as nineteenth century drawings of plague-induced panic, microscopic photographs of HIV and Ebola, and wartime posters warning servicemen against syphilis and gonorrhea. From cholera to chlamydia, TB to HIV, bubonic plague to Lyme disease, rabies to Congo-Crimean encephalitis, anthrax to Zika fever, and back to good old rhinitis (the common cold), A Field Guide to Germs is both a handy reference work to better understand today's headlines and a fascinating look at the astonishing impact of micro-organisms on social and political history.
A Field Guide to Lies: Critical Thinking in the Information Age
by Daniel J. LevitinWinner of the Mavis Gallant Prize for Non-FictionWinner of the 2017 National Business Book AwardShortlisted for the 2016/2017 Donner PrizeFrom the bestselling author of The Organized Mind, the must-have book about how to analyze who and what to trust in the age of information overload. It's becoming harder to separate the wheat from the digital chaff. How do we distinguish misinformation, pseudo-facts, distortions and outright lies from reliable information? In A Field Guide to Lies, neuroscientist Daniel Levitin outlines the many pitfalls of the information age and provides the means to spot and avoid them. Levitin groups his field guide into two categories--statistical infomation and faulty arguments--ultimately showing how science is the bedrock of critical thinking. It is easy to lie with stats and graphs as few people "take the time to look under the hood and see how they work." And, just because there's a number on something, doesn't mean that the number was arrived at properly. Logic can help to evaluate whether or not a chain of reasoning is valid. And "infoliteracy" teaches us that not all sources of information are equal, and that biases can distort data. Faced with a world too eager to flood us with information, the best response is to be prepared. A Field Guide to Lies helps us avoid learning a lot of things that aren't true.

From fallout to radiation poisoning, alpha particles to cosmic rays, Biddle illuminates the history, meaning, and health implications of one hundred scientific terms in succinct, witty essays. A Field Guide to Radiation is an essential, engaging handbook that offers wisdom and common sense for today's increasingly nuclear world. .
A Field Guide to Responsible Investing: Asset Management in the Age of Polycrises
by Amy O'BrienFor years, responsible investing has been a bewildering precinct in asset management. To many, the idea of aligning your values with your investment portfolio seemed naive. Slowly and steadily, responsible investing morphed from a movement into an industry on course to command $50 trillion in assets by 2025— a third of the capital at work in the markets. And yet responsible investing has remained as difficult to traverse as ever. It&’s drawn fire from critics who&’ve branded the approach &“woke capitalism&” whilst more &“responsible&” generations of investors are poised to marshal trillions of assets of their own into the business - we are at an inflection point. As a responsible investing practitioner for more than 25 years, author Amy O&’Brien has taken part in this revolution in asset management. With geopolitical conflicts, economic instability, and climate change fomenting unprecedented &“polycrises&”, she believes there is no more effective way to address the challenges of the 21st century than through responsible investing. Like most tectonic shifts in asset management, responsible investing has been complicated, hard to define, and hard to measure. But doing so is not only possible, it's also imperative. Over nine chapters, the book takes readers on a journey of the evolution of responsible investing, how it works today, why it&’s integral to investment considerations, and how we can finally get a grip on its efficacy. It&’s time to demystify and unpack this invaluable method for managing our assets, and our futures.
