Hard As the Rock Itself

by David Robertson

The first intensive analysis of sense of place in American mining towns, Hard as the Rock Itself: Place and Identity in the American Mining Town provides rare insight into the struggles and rewards of life in these communities. David Robertson contends that these communities - often characterized in scholarly and literary works as derelict, as sources of debasing moral influence, and as scenes of environmental decay - have a strong and enduring sense of place and have even embraced some of the signs of so-called dereliction. Robertson documents the history of Toluca, Illinois; Cokedale, Colorado; and Picher, Oklahoma, from the mineral discovery phase through mine closure, telling for the first time how these century-old mining towns have survived and how sense of place has played a vital role. Acknowledging the hardships that mining's social, environmental, and economic legacies have created for current residents, Robertson argues that the industry's influences also have contributed to the creation of strong, cohesive communities in which residents have always identified with the severe landscape and challenging, but rewarding way of life. Robertson contends that the tough, unpretentious appearance of mining landscapes mirrors qualities that residents value in themselves, confirming that a strong sense of place in mining regions, as elsewhere, is not necessarily wedded to an attractive aesthetic or even to a thriving economy.

Hard Road West: History and Geology along the Gold Rush Trail

by Keith Heyer Meldahl

In 1848 news of the discovery of gold in California triggered an enormous wave of emigration toward the Pacific. Lured by the promise of riches, thousands of settlers left behind the forests, rain, and fertile soil of the eastern United States in favor of the rough-hewn lands of the American West.

Hard Road West: History and Geology along the Gold Rush Trail (Chicago Lectures In Physics Ser.)

by Keith Heyer Meldahl

The dramatic journeys of the 19th century Gold Rush come to life in this geologist&’s tour of the American West and the events that shaped the land. In 1848, news of the discovery of gold in California triggered an enormous wave of emigration toward the Pacific. The dramatic terrain these settlers crossed is so familiar to us now that it is hard to imagine how frightening—even godforsaken—its sheer rock faces and barren deserts once seemed to them. Hard Road West brings their perspective vividly to life, weaving together the epic overland journey of the covered wagon trains and the compelling story of the landscape they encountered. Taking readers along the 2,000-mile California Trail, Keith Meldahl uses settler&’s diaries and letters—as well as his own experiences on the trail—to reveal how the geology and geography of the West shaped our nation&’s westward expansion. He guides us through a landscape of sawtooth mountains, following the meager streams that served as lifelines through an arid land, all the way to California itself, where colliding tectonic plates created breathtaking scenery and planted the gold that lured travelers west in the first place. &“Alternates seamlessly between vivid accounts of the 19th-century journey and lucid explanations of the geological events that shaped the landscape traveled.&”—Library Journal

Hard Rock Hydraulics: An Introduction to Modeling

by Fernando Olavo Franciss

Hard rock hydraulics concerns arrangements of adjoining intact rock blocks, occurring down to a depth of hundreds of meters, where groundwater percolates within the gaps between these blocks. During the last decades, technical papers related to successful or failed attempts for mining groundwater from hard rocks, and achievements or failures of public or mining developments with respect to these rocks, increased the knowledge of their hydraulics. Examples of activities where the mechanical behavior of these rocks highly interacts with their hydraulics are projects under the sea or groundwater level, such as open pits or underground mines, galleries, tunnels, shafts, underground hydropower plants, oil and LPG storage caverns, and deep disposal of hazardous waste. This book dedicated to hard rock hydraulics assumes some prior knowledge of hydraulics, geology, hydrogeology, and soil and rock mechanics. Chapter I discusses the main issues of modeling; chapter II covers the fundamentals of hard rock hydraulics; chapter III presents concepts regarding approximate solutions; chapter IV discusses data analysis for groundwater modeling; chapter V focuses on finite differences and chapter VI provides examples of some particular unusual applications. This book will help civil and mining engineers and also geologists to solve their practical problems in hydrogeology and public or mining projects.

Hard Rock Mine Reclamation: From Prediction to Management of Acid Mine Drainage

by Bruno Bussière Marie Guittonny

Hard rock mines have significant effects on the territories where they operate, through both infrastructure construction as well as resource use. Due to their extractive activities, these mines store large quantities of wastes at the surface, which can be both physically and chemically unstable. Reclamation aims to return a mine site to a satisfactory state, meaning that the site should not threaten human health or security, should not generate in the long term any contaminant that could significantly affect the surrounding environment, and should be aesthetically acceptable to communities. This book focuses on the reclamation of waste storage areas, which constitute the main source of pollution during and after mine operations, and especially issues with acid mine drainage and neutral contaminated drainage. Features: Provides fundamental information and describes practical methods to reclaim mine-waste facilities Compares the different methods and illustrates their application at sites through case studies Identifies new reclamation issues and proposes solutions to address them Presents existing and new technologies to reclaim mine waste disposal areas from hard rock mines in different climatic conditions Integrates reclamation into mine operations and long term performance of techniques used through an interdisciplinary approach With mine site reclamation a young and still emerging science, the training needs for professionals and students working in this field are huge. This book is written from an engineering point of view and in it the authors identify new reclamation issues and propose well-tested as well as innovative approaches to addressing them. Students in graduate programs focused on mines and the environment as well as professionals already working in departments related to mine site reclamation will find this book to be a valuable and essential resource.

Hard Scrabble to Hallelujah, Volume 1: Legacies of Terrebonne Parish, Louisiana (America's Third Coast Series)

by Christopher Everette Cenac Sr.

Winner of a 2017 Louisiana Endowment for the Humanities Book of the Year AwardThis book represents the first time that the known history and a significant amount of new information has been compiled into a single written record about one of the most important eras in the south-central coastal bayou parish of Terrebonne. The book makes clear the unique geographical, topographical, and sociological conditions that beckoned the first settlers who developed the large estates that became sugar plantations. This first of four planned volumes chronicles details about founders and their estates along Bayou Terrebonne from its headwaters in the northern civil parish to its most southerly reaches near the Gulf of Mexico. Those and other parish plantations along important waterways contributed significantly to the dominance of King Sugar in Louisiana. The rich soils and opportunities of the area became the overriding reason many well-heeled Anglo-Americans moved there to join Francophone locals in cultivating the crop. From that nineteenth century period up to the twentieth century’s side effects of World Wars I and II, Hard Scrabble to Hallelujah, Volume I: Bayou Terrebonne describes important yet widely unrecognized geography and history. Today, cultural and physical legacies such as ex-slave-founded communities and place names endure from the time that the planter society was the driving economic force of this fascinating region.

Hard X-Ray Imaging of Solar Flares

by Michele Piana A. Gordon Emslie Anna Maria Massone Brian R. Dennis

The idea for this text emerged over several years as the authors participated in research projects related to analysis of data from NASA's RHESSI Small Explorer mission. The data produced over the operational lifetime of this mission inspired many investigations related to a specific science question: the when, where, and how of electron acceleration during solar flares in the stressed magnetic environment of the active Sun.A vital key to unlocking this science problem is the ability to produce high-quality images of hard X-rays produced by bremsstrahlung radiation from electrons accelerated during a solar flare. The only practical way to do this within the technological and budgetary limitations of the RHESSI era was to opt for indirect modalities in which imaging information is encoded as a set of two-dimensional spatial Fourier components. Radio astronomers had employed Fourier imaging for many years. However, differently than for radio astronomy, X-ray images produced by RHESSI had to be constructed from a very limited number of sparsely distributed and very noisy Fourier components. Further, Fourier imaging is hardly intuitive, and extensive validation of the methods was necessary to ensure that they produced images with sufficient accuracy and fidelity for scientific applications.This book summarizes the results of this development of imaging techniques specifically designed for this form of data. It covers a set of published works that span over two decades, during which various imaging methods were introduced, validated, and applied to observations. Also considering that a new Fourier-based telescope, STIX, is now entering its nominal phase on-board the ESA Solar Orbiter, it became more and more apparent to the authors that it would be a good idea to put together a compendium of these imaging methods and their applications. Hence the book you are now reading.

Hardware, Software, Heartware: Digital Twinning for More Sustainable Built Environments

by Jason Pomeroy

This richly illustrated book examines the full potential of Digital Twins (DTs) as a means of creating more sustainable urban habitats. It reveals how, in this digitally-enabled age, DTs are increasingly being adopted by cities as a tool for urban governance, with the hope of increasing operational efficiencies and enhancing citizens’ lives. While the study and implementation of DTs has been critically explored as virtual, dynamic 3D replicas of physical entities across different disciplines and industries, this book establishes a strategy that recognises the need for the ‘software’ behind virtual DT platforms to not only represent the ‘hardware’ of our physical cities but also to reflect the ‘heartware’ of socio-economic and cultural practices. Knowledge gaps and challenges in existing DTs are identified and insights into rethinking their purpose are provided to propose a new DT paradigm model for city-wide application. With multiple case studies illustrating the different concepts of DTs being applied in cities from Europe, North America, The Middle East, Asia and Oceania, the book highlights the reasons why and how DTs can play an integral role in the sustainability of our urban habitats. Beautifully designed and illustrated in full colour throughout, this book combines academic theory with practical application and will be a useful reference for professionals, students, academics and policymakers, working in the fields of smart cities, sustainable urbanism, and the digitisation, digitalisation and digital transformation of the built environment industry.

Harmonic Proportion and Form in Nature, Art and Architecture (General Science)

by Samuel Colman

A treatise on the laws governing proportional form in both nature and the arts and sciences, this well-illustrated volume amply demonstrates how a design's geometrical construction can captivate both the eye and the mind. Flowers, shells, and other natural organisms appear here, along with artistic creations, in a mathematical study of the similarity of their constructive principles. These principles, in turn, are the fundamental elements by which nature creates harmony.The author, Samuel Colman (1832–1920), was a prominent member of the Hudson River School of painters ("Storm King on the Hudson," his 1866 oil on canvas, is one of his best-known works), and an embodiment through his life and work of the school's celebration of nature through art. As an activist in the politics of art, Colman helped form the Society of American Artists as well as the American Society of Painters in Water Colors, a relatively new medium at the time. He was also a teacher and associate of Louis Comfort Tiffany; in 1879, the two joined forces to establish an interior design firm that included Mark Twain among its clientele.This handsome and provocative volume is enhanced by 302 drawings by the author that complement and amplify each subject area discussed. It also includes an important Mathematical Analysis by the editor, C. Arthur Coan. As a multifaceted study, this book will find an audience among artists and philosophers, as well as scientists and mathematicians.

Harmony: A New Way of Looking at Our World

by The Prince of Wales Tony Juniper Ian Skelly

For the first time, His Royal Highness Charles, the Prince of Wales, shares his views on how mankind’s most pressing modern challenges are rooted in our disharmony with nature. In the vein of Al Gore’s An Inconvenient Truth and Van Jones’ Green Collar Economy, Prince Charles presents the compelling case that solutions to our most dire crises—from climate change to poverty—lie in regaining a balance with the world around us.

Harness the Sun

by Philip Warburg

Going from the inner city to the open desert, a seasoned environmental advocate looks at solar energy's remarkable ascent and its promise for America's future Solar power was once the domain of futurists and environmentally minded suburbanites. Today it is part of mainstream America. Scan the skyline of downtown neighborhoods, check out the rooftop of the nearest Walmart, and take a close look at your local sports arena. Chances are you'll find solar panels in those and many other unexpected places. In Harness the Sun, Philip Warburg takes readers on a far-flung journey that explores America's solar revolution. Beginning with his solar-powered home in New England, he introduces readers to the pioneers who are spearheading our move toward a clean energy economy. We meet the CEOs who are propelling solar power to prominence and the intrepid construction workers who scale our rooftops installing panels. We encounter the engineers who are building giant utility-scale projects in prime solar states like Nevada, Arizona, and California, and the biologists who make sure wildlife is protected at those sites. Warburg shows how solar energy has won surprising support across the political spectrum. Prominent conservatives embrace solar power as an emblem of market freedom, while environmental advocates see it as a way to reduce America's greenhouse gas emissions. At the same time, economic-justice activists celebrate solar's potential to lift up low-income communities, and Native American leaders welcome the income and jobs that the industry will bring to their communities. Yet solar energy has its downsides and detractors too. Conservationists worry about the impact of large solar farms on protected animal species, and some local citizens groups resent the encroachment of solar projects on farmland and open spaces. Warburg gives voice to those at the epicenter of these conflicts and points the way to constructive solutions. Harness the Sun offers a grounded, persuasive vision of America's energy future. It is a future fueled by clean, renewable sources of power, with solar at center stage.

Harnessing Dividends From Drylands

by K. V. Raju Suhas P. Wani

The livelihoods of millions of people in developing countries depend on Dryland agriculture to ensure their food security and their well-being. Any improvement in yields for farmers in these areas will have a significant positive affect. This book describes lessons learned from an innovative scheme in India that improved yields in drylands. It shows how the scheme can be scaled up for other Dryland regions of the world. The scheme uses localized soil nutrient analyses to create an integrated, climate-smart fertilizer and planting plan that maximizes yields for farmers.

Harnessing Dividends from Drylands: Innovative Scaling up with Soil Nutrients

by Kanwar Sahrawat Girish Chander G. Pardhasaradhi K. Krishnappa K. H. Anantha Gajanan Sawargaonkar Mukund Patil V. Nageswara Rao A.V.R. Kesava Rao K Srinivas Raghavendra Sudi Kaushal Garg

The livelihoods of millions of people in developing countries, which depend on dryland agriculture to ensure their food security and their well-being, could be improved measurably by gains in agricultural crop yields. This book describes lessons learnt from an innovative scheme in India that improved crop yields in drylands. It shows how the scheme can be scaled up for other dryland regions of the world. The scheme uses localized soil nutrient analyses to create an integrated, climate smart fertilizer and planting plan that maximises yields for farmers. This book describes how a partnership between a global scientific organization (such as International Crops Research Institute for the Semi-Arid Tropics, ICRISAT) and state and non-state actors can provide a route to equitable growth, specifically for small and marginal farmers, and how this approach can be replicated worldwide to enhance rural livelihoods. This strategic collaboration and its conceptual and functional design is fully outlined, as well as the scheme's implementation and the effective monitoring and learning process that has been created.

Harnessing Foreign Investment to Promote Environmental Protection

by Pierre-Marie Dupuy Jorge E. Viñuales

Harnessing Foreign Investment to Promote Environmental Protection investigates the main challenges facing the implementation of environmental protection and the synergies between foreign investment and environmental protection. Adopting legal, economic and political perspectives, the contributing authors analyse the various incentives which encourage foreign investment into pro-environment projects (such as funds, project-finance, market mechanisms, payments-for-ecosystem services and insurance) and the safeguards against its potentially harmful effects (investment regulation, CSR and accountability mechanisms, contracts and codes of conduct).

Harnessing Renewable Energy in Electric Power Systems: Theory, Practice, Policy

by Richard Schmalensee Boaz Moselle Jorge Padilla

Reflecting its reliance on fossil fuels, the electric power industry produces the majority of the world's greenhouse gas emissions. The need for a revolution in the industry becomes further apparent given that 'decarbonization' means an increasing electrification of other sectors of the economy�in particular, through a switch from gasoline to electric vehicles. Of the options for producing electric power without significant greenhouse gas emissions, renewable energy is most attractive to policymakers, as it promises increased national self-reliance on energy supplies and the creation of new industries and jobs, without the safety and political concerns of nuclear power or the unproven technology of carbon capture and storage. Drawing on both economic theory and the experiences of the United States and EU member states, Harnessing Renewable Energy addresses the key questions surrounding renewable energy policies. How appropriate is the focus on renewable power as a primary tool for reducing greenhouse gas emissions? If renewable energy is given specific support, what form should that support take? What are the implications for power markets if renewable generation is widely adopted? Thorough and well-evidenced, this book will be of interest to a broad range of policymakers, the electric power industry, and economists who study energy and environmental issues.

Harnessing the Power of Collective Learning: Feedback, accountability and constituent voice in rural development

by Roy Steiner Duncan Hanks

What were new ideas 30 years ago, such as the concepts of participatory development and systems thinking, are now accepted norms in international development circles. The majority of professionals engaged in rural development accept the proposition that the people who participate in development should play an active role in defining, implementing, and evaluating projects intended to improve their productivity and lives. However this goal remains unrealized in many development programs. Harnessing the Power of Collective Learning considers the challenges and potential of enabling collective learning in rural development initiatives. The book presents 11 case studies of organizations trying to develop and implement collective learning systems as an integral component of sustainable development practice. Through systematic reflection on action and experience, key lessons and themes emerge regarding the nature of voice, participation, feedback loops, accountability and transparency, that will be useful for many others in the development community. This book is a useful resource for academics, practitioners and policy makers in the areas of international development, sustainable development, organizational development, philanthropy, learning communities, monitoring and evaluation and rural development.

Harnessing Urban Innovation to Unlock the Sustainable Development Goals (Urban Sustainability)

by Ali Cheshmehzangi Nicholas You José Siri Eugénie Birch

This book first attempts to explore the nexus between urban innovation and sustainable development goals (SDGs). It puts together global examples of urban innovation initiatives, highlighting practical, policy-oriented, social, and technological interventions. The case studies are divided into four clusters of ‘green cities’, ‘inclusive cities’, ‘resilient cities’, and ‘healthy cities’. In doing so, the book maps various global examples of urban innovation for sustainable pathways and directions. It also highlights means of implementation of tool and technologies, data, financing, and governance. The overarching aim is to provide a holistic overview of urban innovation sustainable development nexus, which would help future policy development, paradigm shifts, and technological applications.By summarising a selection of successful initiatives, interventions, and projects, this book highlights how urban innovation could accelerate achieving SDGs. The lessons learned from each case study cluster are narrated as knowledge transfer platforms for future city development and achieving sustainable development. These lessons will be beneficial to practitioners and governments, as well as researchers and academics who are interested in urban innovation research. City case studies included in the book are based on their success stories as role models for other cities in developed and developing nations. This collection helps us portray a more holistic image of urban innovation aligned with the SDGs and pathways to achieving them.

Harpers Ferry National Historical Park (Images of America)

by James A. Beckman

Harpers Ferry National Historical Park is a jewel of America's National Park Service. Established by legislation and signed into law by President Roosevelt in 1944, today the park encompasses thousands of acres spanning three states as well as the confluence of the Shenandoah and Potomac Rivers. While the town was ravaged by repeated floods and war, it rose like a phoenix from the ashes. As a Civil War soldier presciently wrote, "In future years travelers and tourists will eagerly resort [here] . . . and history will point out [this] spot where many acts of the great tragedy, not yet closed, took place." This book chronicles the creation and development of the national park in Harpers Ferry, a park that now affords hundreds of thousands of visitors each year the opportunity to marvel at the same scenery Thomas Jefferson said was worth a voyage across the Atlantic to see and to be able to walk the old streets where so many major acts of American history took place.

Harriman State Park

by Ronnie Clark Coffey

Once home to Native Americans and mountain settlers, Harriman State Park is today a 73-square-mile wilderness and recreation area lying 30 miles north of New York City. Offering over 200 miles of hiking trails, swimming, boating, fishing, and camping, it has been an oasis for city dwellers for 100 years. During the 1800s, the land was home to hardworking farmers, miners, and woodcutters. As the new century dawned, it evolved into a park of stunning beauty. Part of the Palisades Interstate Park System, it is the second-largest state park in New York.
