The Longest Race: A Lifelong Runner, An Iconic Ultramarathon, and the Case for Human Endurance
by Ed Ayres“It soon becomes clear that this book isn’t just about an athletic race. It’s also about the human race” (Bloomberg Businessweek). Having run in more than six hundred races over the span of fifty-five years, Ed Ayres is a legendary distance runner—and this book is his urgent exploration of the connection between individual endurance and a sustainable society. The Longest Race begins at the starting line of the 2001 JFK 50 Mile—the nation’s oldest and largest ultramarathon and, like other such races, it’s an epic test of human limits and aspiration. At age sixty, his sights set on breaking the age-division record, Ayres embarks on a course over the rocky ridge of the Appalachian Trail, along the headwind-buffeted towpath of the Potomac River, and past momentous Civil War sites such as Harpers Ferry and Antietam. But even as Ayres focuses on an endurance runner’s familiar concerns—starting strong and setting the right pace, controlling his breathing, overcoming fatigue, and staying mindful of the course ahead—he finds himself as preoccupied with the future of our planet as with the finish line. A veteran journalist and environmental editor, Ayres reveals how the skills and mindset necessary to complete an ultramarathon are also essential for grappling anew with the imperative to endure—not only as individuals, but as a society—and not just for fifty miles, but over the real long haul, in a unique meditation that “ought to be required reading even for people who have never run a step” (The Boston Globe). “He seamlessly moves between discussing running to exploring larger life issues such as why we run, our impact on the environment, and the effects of the nation’s declining physical fitness . . . Thought provoking.” ―Booklist “To read this book is to run alongside a seasoned athlete, a deep thinker, and a great storyteller. And Ayres doesn’t disappoint: He is the best kind of running companion, generously doling out hilarious stories and hard-won insights into performance conditioning and the human condition. His lifetime of ultra-running and environmental writing drive his exploration of what keeps us running long distances―and what it might take to keep the planet from being run into the ground.” ―Nature Conservancy magazine

Longleaf, Far as the Eye Can See
by John C. Hall Bill Finch Beth Maynor Young Rhett JohnsonLongleaf forests once covered 92 million acres from Texas to Maryland to Florida. These grand old-growth pines were the "alpha tree" of the largest forest ecosystem in North America and have come to define the southern forest. But logging, suppression of fire, destruction by landowners, and a complex web of other factors reduced those forests so that longleaf is now found only on 3 million acres. Fortunately, the stately tree is enjoying a resurgence of interest, and longleaf forests are once again spreading across the South. Blending a compelling narrative by writers Bill Finch, Rhett Johnson, and John C. Hall with Beth Maynor Young's breathtaking photography, Longleaf, Far as the Eye Can See invites readers to experience the astounding beauty and significance of the majestic longleaf ecosystem. The authors explore the interactions of longleaf with other species, the development of longleaf forests prior to human contact, and the influence of the longleaf on southern culture, as well as ongoing efforts to restore these forests. Part natural history, part conservation advocacy, and part cultural exploration, this book highlights the special nature of longleaf forests and proposes ways to conserve and expand them.
Longwall Mining, 3rd Edition
by Syd S. PengIn the past 13 years since the publication of Longwall Mining, 2nd edition in 2006, although there have been no major changes in longwall mining technology and operations, many incremental developments in the whole system as well as various subsystems of the existing longwall mining operational technologies as detailed in the 2nd edition have been added to this edition. Major developments are automation, and health and safety technology, as well as equipment reliability, thereby greatly increasing productivity and cutting cost. In particular, the longwall system can now run automatically cut by cut forever without operators' intervention provided that the geology allows it. Other health and safety features such as LASC, personal proximity detection, color lighting, automatic shield water sprays and remote shearer control are fully operational. There are more than 7000 sensors installed in current longwall mining systems. The big data obtained and fast communication technology have been fully utilized to improve and solve operational problems in real time. Those features are fully documented in the new edition. In pursuit of high productivity and cutting cost, life cycle management that increases equipment reliability has been implemented by OEM. Automation improvement such as tail-end automatic chain tensioner greatly extends AFC chain's service life. Other incremental improvements including dust and methane controls, entry development, panel design and face move are addressed. Additional operational issues such as extension of panel width and compatibility test are also discussed. Since the last plow longwall mine was closed in 2018, the chapter on plow longwalling has been dropped and in its place Automation of Longwall Components and System is added. Also, a new chapter Longwall Top Coal Caving Mining (LTCC) is added due to its successful application in Australia since 2005. Longwall Mining, 3rd edition will be of interest to professionals and academics in the field of mining engineering specifically, serving both as a reference work and an (under)graduate textbook, but will also interest civil, geomechanical and geological engineers and rock mechanics professionals, as well as coal operators, mining consultants, researchers, equipment manufacturers, and government regulators.

Looking for Longleaf
by Lawrence S. EarleyCovering 92 million acres from Virginia to Texas, the longleaf pine ecosystem was, in its prime, one of the most extensive and biologically diverse ecosystems in North America. Today these magnificent forests have declined to a fraction of their original extent, threatening such species as the gopher tortoise, the red-cockaded woodpecker, and the Venus fly-trap. Conservationists have proclaimed longleaf restoration a major goal, but has it come too late?In Looking for Longleaf, Lawrence S. Earley explores the history of these forests and the astonishing biodiversity of the longleaf ecosystem, drawing on extensive research and telling the story through first-person travel accounts and interviews with foresters, ecologists, biologists, botanists, and landowners. For centuries, these vast grass-covered forests provided pasture for large cattle herds, in addition to serving as the world's greatest source of naval stores. They sustained the exploitative turpentine and lumber industries until nearly all of the virgin longleaf had vanished. Looking for Longleaf demonstrates how, in the twentieth century, forest managers and ecologists struggled to understand the special demands of longleaf and to halt its overall decline. The compelling story Earley tells here offers hope that with continued human commitment, the longleaf pine might not just survive, but once again thrive.Covering 92 million acres from Virginia to Texas, the longleaf pine ecosystem was, in its prime, one of the most extensive and biologically diverse ecosystems in North America.

Looking into the Earth: An introduction to geological geophysics
by Alan E. Mussett M. Aftab KhanLooking Into the Earth comprehensively describes the principles and applications of both 'global' and 'exploration' geophysics on all scales. It forms an introduction to geophysics suitable for those who do not necessarily intend to become professional geophysicists, including geologists, civil engineers, environmental scientists, and field archaeologists. The book is organised into two parts: Part 1 describes the geophysical methods, while Part 2 illustrates their use in a number of extended case histories. Mathematical and physical principles are introduced at an elementary level, and then developed as necessary. Student questions and exercises are included at the end of each chapter. The book is aimed primarily at introductory and intermediate university students taking courses in geology, earth science, environmental science, and engineering. It will also form an excellent introductory textbook in geophysics departments, and will help practising geologists, archaeologists and engineers understand what geophysics can offer their work.
Looking Up: The True Adventures of a Storm-Chasing Weather Nerd
by Matthew CappucciAn energetic and electrifying narrative about all things weather—by one of today's rising meteorological stars.Get in—we&’re going storm-chasing! Imagine a very cool weather nerd has just pulled up to you and yelled this out the window of his custom-built armored storm-chasing truck. The wind is whipping around, he&’s munching on Wawa, it&’s all very chaotic—yet as you look into his grinning face, you feel the greatest surge of adrenaline you have ever felt in your life. Hallelujah: your cavalry is here! Welcome to the brilliance of Looking Up, the lively new book from rising meterology star Matthew Cappucci. He&’s a meteorologist for The Washington Post, and you might think of him as Doogie Howser meets Bill Paxton from Twister, with a dash of Leonardo DiCaprio from Catch Me If You Can. A self-proclaimed weather nerd, at the age of fourteen he talked his way into delivering a presentation on waterspouts at the American Meteorological Society's annual broadcast conference by fudging his age on the application and created his own major on weather science while an undergrad at Harvard. Combining reportage and accessible science with personal storytelling and infectious enthusiasm, Looking Up is a riveting ride through the state of our weather and a touching story about parents and mentors helping a budding scientist achieve his improbable dreams. Throughout, readers get a tutorial on the basics of weather science and the impact of the climate. As our country&’s leaders sound the alarm on climate change, few people have as close a view to how serious the situation actually is than those whose job is to follow the weather, which is the daily dose of climate we interact with and experience every day. The weather affects every aspect of our lives (even our art) as well as our future. The way we think about it requires a whole-life overhaul. Rain or shine, tropical storm or twister, Cappucci is here to help us begin the process. So get in his storm-chasing truck already, will ya?
Lookout: Love, Solitude, and Searching for Wildfire in the Boreal Forest
by Trina MoylesA page-turning memoir about a young woman's grueling, revelatory summers working alone in a remote lookout tower and her eyewitness account of the increasingly unpredictable nature of wildfire in the Canadian north.While growing up in Peace River, Alberta, Trina Moyles heard many stories of Lookout Observers--strange, eccentric types who spent five-month summers alone, climbing 100-foot high towers and watching for signs of fire in the surrounding boreal forest. How could you isolate yourself for that long? she wondered. "I could never do it," she told herself. Craving a deeper sense of purpose, she left northern Alberta to pursue a decade-long career in global humanitarian work. After three years in East Africa, and newly engaged, Trina returned to Peace River with a plan to sponsor her fiance, Akello's, immigration to Canada. Despite her fear of being alone in the woods, she applied for a seasonal lookout position and got the job. Thus begins Trina's first summer as one of a handful of lookouts scattered throughout Alberta, with only a farm dog, Holly--labeled "a domesticated wolf" by her former owners--to keep her company. While searching for smoke, Trina unravels under the pressure of a long-distance relationship--and a dawning awareness of the environmental crisis that climate change is producing in the boreal. Through megafires, lightning storms, and stunning encounters with wildlife, she learns to survive at the fire tower by forging deep connections with nature and with an extraordinary community of people dedicated to wildfire detection and combat. In isolation, she discovers a kind of self-awareness--and freedom--that only solitude can deliver. Lookout is a riveting story of loss, transformation, and belonging to oneself, layered with an eyewitness account of the destructive and regenerative power of wildfire in our northern forests.
The Loom of Time: Between Empire and Anarchy, from the Mediterranean to China
by Robert D. KaplanA stunning exploration of the Greater Middle East, where lasting stability has often seemed just out of reach but may hold the key to the shifting world order of the twenty-first century&“Engaging . . . Even those who resist Kaplan&’s tragic sensibility have much to learn from his look at the emerging Middle East and its recent history.&”—National Review The Greater Middle East, which Robert D. Kaplan defines as the vast region between the Mediterranean and China, encompassing much of the Arab world, parts of northern Africa, and Asia, existed for millennia as the crossroads of empire: Macedonian, Roman, Persian, Mongol, Ottoman, British, Soviet, American. But with the dissolution of empires in the twentieth century, postcolonial states have endeavored to maintain stability in the face of power struggles between factions, leadership vacuums, and the arbitrary borders drawn by exiting imperial rulers with little regard for geography or political groups on the ground. In the Loom of Time, Kaplan explores this broad, fraught space through reporting and travel writing to reveal deeper truths about the impacts of history on the present and how the requirements of stability over anarchy are often in conflict with the ideals of democratic governance. In The Loom of Time, Kaplan makes the case for realism as an approach to the Greater Middle East. Just as Western attempts at democracy promotion across the Middle East have failed, a new form of economic imperialism is emerging today as China's ambitions fall squarely within the region as the key link between Europe and East Asia. As in the past, the Greater Middle East will be a register of future great power struggles across the globe. And like in the past, thousands of years of imperial rule will continue to cast a long shadow on politics as it is practiced today. To piece together the history of this remarkable place and what it suggests for the future, Kaplan weaves together classic texts, immersive travel writing, and a great variety of voices from every country that all compel the reader to look closely at the realities on the ground and to prioritize these facts over ideals on paper. The Loom of Time is a challenging, clear-eyed book that promises to reframe our vision of the global twenty-first century.
Loop de Loop: Circular Solutions for a Waste-Free World
by Andrea CurtisGet loopy with this playful introduction to the hopeful, transformative possibilities of circular systems! Nature works on a cycle, where everything in the loop has value and nothing is wasted. But modern humans have created a different kind of system: it’s less like a circle and more like a line. We take, make, use and then, when those things break or we’re finished with them, we toss them away. But our planet’s resources are limited, and we’ve taken too much. That’s why all over the world, people are reusing, repurposing, repairing and designing waste out of the system! Explore the ways that people everywhere are creating a loopier world: from growing building materials out of fungi to designing headphones (and cellphones!) that last, to producing vehicles that run on renewable energy. Plus, kids and families have a role to play, too. Loop de Loop introduces young readers to repair cafés, toy rentals, tool libraries and many more fun, innovative ways to build community and a more sustainable world. Includes a list of ways children can take part in circular systems, along with a glossary and sources for further reading.

Loop Quantum Gravity for the Bewildered: The Self-Dual Approach Revisited
by Sundance Bilson-ThompsonThis second edition offers a comprehensive introduction to loop quantum gravity (LQG) in self-dual variables, including the necessary prerequisites. Additionally, it delves into various significant research areas that have emerged in recent years. New content (including an entirely new chapter dedicated to dynamics of quantum spacetime) explores the description of spin networks and spin-foams, their historical development as well as connections to tensor networks, BF theory, and emerging approaches including the spinorial representation of LQG, SU(2) coherent states, and group field theory. Furthermore, the book provides expanded appendices covering essential tools and concepts, such as the connection between information theory and entropy, and overviews of group theory and differential geometry. All topics are presented from a non-expert perspective, ensuring self-containment and accessibility. The primary aim of this second edition remains helping researchers, bewildered bythe vast array of topics within this rapidly growing field of quantum gravity, to gain a fundamental understanding of the current developments.
The Looting Machine
by Tom BurgisThe trade in oil, gas, gems, metals and rare earth minerals wreaks havoc in Africa. During the years when Brazil, India, China and the other "emerging markets” have transformed their economies, Africa’s resource states remained tethered to the bottom of the industrial supply chain. While Africa accounts for about 30 per cent of the world’s reserves of hydrocarbons and minerals and 14 per cent of the world’s population, its share of global manufacturing stood in 2011 exactly where it stood in 2000: at 1 percent. In his first book, The Looting Machine, Tom Burgis exposes the truth about the truth about the African development miracle: for the resource states, it's a mirage. The oil, copper, diamonds, gold and coltran deposits just attract a global network of traders, bankers, corporate extractors and investors who combine with venal political cabals to loot the states' value . And the vagaries of resource-dependent economies could pitch Africa’s new middle class back into destitution just as quickly as they climbed out of it. The ground beneath their feet is as precarious as a Congolese mine shaft; their prosperity could spill away like crude from a busted pipeline. This catastrophic social disintegration is not merely a continuation of Africa’s past as a colonial victim. The looting now is accelerating as never before. As global demand for Africa’s resources rises, a handful of Africans are becoming legitimately rich but the vast majority, like the continent as a whole, are being fleeced. Outsiders tend to think of Africa as a great drain of philanthropy. But look more closely at the resource industry and the relationship between Africa and the rest of the world looks rather different. In 2010, fuel and mineral exports from Africa were worth $333 billion, more than seven times the value of the aid that went in the opposite direction. But who received the money? For every Frenchwoman who dies in childbirth, 100 die in Niger alone, the former French colony whose uranium fuels France’s nuclear reactors. In petro-states like Angola three-quarters of government revenue comes from oil. The government is not funded by the people, and as result it is not beholden to them. A score of African countries whose economies depend on resources are rentier states; their people are largely serfs. The resource curse is not merely some unfortunate economic phenomenon, the product of an intangible force. What is happening in Africa’s resource states is systematic looting. Like its victims, its beneficiaries have names.

Lorentz Symmetry Breaking—Classical and Quantum Aspects (SpringerBriefs in Physics)
by Tiago Mariz Jose Roberto Nascimento Albert PetrovThis book presents a review of various issues related to Lorentz symmetry breaking. Explicitly, we consider (i) motivations for introducing Lorentz symmetry breaking, (ii) classical aspects of Lorentz-breaking field theory models including typical forms of Lorentz-breaking additive terms, wave propagation in Lorentz-breaking theories, and mechanisms for breaking the Lorentz symmetry; (iii) quantum corrections in Lorentz-breaking theories, especially the possibilities for perturbation generating the most interesting Lorentz-breaking terms; (iv) correspondence between non-commutative field theories and Lorentz symmetry breaking; (v) supersymmetric Lorentz-breaking theories; and (vi) Lorentz symmetry breaking in a curved space-time. We close the book with the review of experimental studies of Lorentz symmetry breaking. The importance and relevance of these topics are explained, first, by studies of limits of applicability of the Lorentz symmetry, second, by searches of the possible extensions of the standard model, including the Lorentz-breaking ones, and need to study their properties, third, by the relation between Lorentz symmetry breaking with string theory, fourth, by the problem of formulating a consistent quantum gravity theory, so that various modified gravity models are to be examined.

Los Angeles and the Summer Olympic Games: Planning Legacies (SpringerBriefs in Geography)
by Eva Kassens NoorThis open access book describes the three planning approaches and legacy impacts for the Olympic Games in one locale: the city of Los Angeles, USA. The author critically compares the similarities and differences of the LA Olympics by reviewing the 1932 and 1984 Olympics and by analyzing the concurrent planning process for the 2028 Olympics. The author unravels the conditions that make (or do not make) LA28’s argument “we have staged the Games before, we can do it again” compelling. Setting the bid’s promises into the contemporary local and global mega-event contexts, the author analyzes why LA won the bids, how those wins allowed LA to negotiate concessions with the IOC and NOC, and how legacies were planned, executed, and ultimately evolved. The author concludes with a prediction which 2028 legacy promises might and might not be fulfilled given the local and international Olympic contexts.
The Los Angeles Plaza
by William David EstradaCity plazas worldwide are centers of cultural expression and artistic display. They are settings for everyday urban life where daily interactions, economic exchanges, and informal conversations occur, thereby creating a socially meaningful place at the core of a city. At the heart of historic Los Angeles, the Plaza represents a quintessential public space where real and imagined narratives overlap and provide as many questions as answers about the development of the city and what it means to be an Angeleno. The author, a social and cultural historian who specializes in nineteenth- and early twentieth-century Los Angeles, is well suited to explore the complex history and modern-day relevance of the Los Angeles Plaza. From its indigenous and colonial origins to the present day, Estrada explores the subject from an interdisciplinary and multiethnic perspective, delving into the pages of local newspapers, diaries and letters, and the personal memories of former and present Plaza residents, in order to examine the spatial and social dimensions of the Plaza over an extended period of time. The author contributes to the growing historiography of Los Angeles by providing a groundbreaking analysis of the original core of the city that covers a long span of time, space, and social relations. He examines the impact of change on the lives of ordinary people in a specific place, and how this change reflects the larger story of the city.
Losing Earth: A Recent History
by Nathaniel RichBy 1979, we knew nearly everything we understand today about climate change—including how to stop it. Over the next decade, a handful of scientists, politicians, and strategists, led by two unlikely heroes, risked their careers in a desperate, escalating campaign to convince the world to act before it was too late. Losing Earth is their story, and ours.The New York Times Magazine devoted an entire issue to Nathaniel Rich’s groundbreaking chronicle of that decade, which became an instant journalistic phenomenon—the subject of news coverage, editorials, and conversations all over the world. In its emphasis on the lives of the people who grappled with the great existential threat of our age, it made vivid the moral dimensions of our shared plight.Now expanded into book form, Losing Earth tells the human story of climate change in even richer, more intimate terms. It reveals, in previously unreported detail, the birth of climate denialism and the genesis of the fossil fuel industry’s coordinated effort to thwart climate policy through misinformation propaganda and political influence. The book carries the story into the present day, wrestling with the long shadow of our past failures and asking crucial questions about how we make sense of our past, our future, and ourselves. Like John Hersey’s Hiroshima and Jonathan Schell’s The Fate of the Earth, Losing Earth is the rarest of achievements: a riveting work of dramatic history that articulates a moral framework for understanding how we got here, and how we must go forward.
Losing It All to Sprawl: How Progress Ate My Cracker Landscape (Florida History and Culture)
by Bill BellevilleLosing It All to Sprawl is the poignant chronicle of award-winning nature writer Bill Belleville and how he came to understand and love his historic Cracker farmhouse and "relic" neighborhood in central Florida, even as it was all wiped out from under him. Belleville's narrative is eloquent, informed, and impassioned, a saga in which tractors and backhoes trample through the woods next to his home in order to build the backbone of Florida sprawl--the mall. As heavy machinery encircles Belleville and his community--the noise growing louder and closer, displacing everything Belleville has called home for the past fifteen years--he tells a story that is much older, 10,000 years older. The story stretches back to the Timucua and the Mayaca living in harmony with Florida's environment; the conquistadors who expected much from, but also feared, this "land of flowers"; the turn-of-the-century tourists "modernizing" and "climatizing" the state; the original Cracker families who lived in Belleville's farmhouse. In stark contrast to this millennia-long transformation is the whiplash of unbridled growth and development that threatens the nearby wilderness of the Wekiva River system, consuming Belleville's home and, ultimately, his very sense of place.In Florida, one of the nation's fastest growing states (and where local and state governments encourage growth), balancing use with preservation is an uphill battle. Sprawl spreads into the countryside, consuming not just natural lands but Old Florida neighborhoods and their unique history. In Losing It All to Sprawl, Belleville accounts for the impacts--social, political, natural, personal--that a community in the crosshairs of unsustainable growth ultimately must bear, but he also offers Floridians, and anyone facing the blight of urban confusion, the hope that can be found in the rediscovery and appreciation of the natural landscape.
Losing Paradise: The Water Crisis in the Mediterranean (Voices In Development Management Ser.)
by Gail Holst-Warhaft Tammo SteenhuisTaking a uniquely interdisciplinary view of the Eastern Mediterranean region's water problems, this book considers some of the technical and regulatory solutions being proposed or implemented to solve the difficulties of diminished or polluted water supplies. Stressing the importance of traditional and historical cultural understanding in addressing the water crisis, the authors demonstrate that what is required is an integrated legal, social and scientific management system appropriate to each country's stage of development and their cultural heritage. Using case studies from Lebanon, Italy, Spain, Egypt, Greece, Jordan and Cyprus, the authors focus on the urgency of the present crisis faced by each country and the need for cooperation. The suggested solutions also serve as a paradigm for the rest of the world as it faces similar issues of water shortage.
