Coupled Thermo-Hydro-Mechanical Processes in Fractured Rock Masses: Discrete Element Modeling and Engineering Applications
by Fengshou Zhang Branko Damjanac Jason FurtneyThe subject of thermo-hydro-mechanical coupled processes in fractured rock masses has close relevance to energy-related deep earth engineering activities, such as enhanced geothermal systems, geological disposal of radioactive waste, sequestration of CO2, long-term disposal of waste water and recovery of hydrocarbons from unconventional reservoirs. Despite great efforts by engineers and researchers, comprehensive understanding of the thermo-hydro-mechanical coupled processes in fractured rock mass remains a great challenge. The discrete element method (DEM), originally developed by Dr. Peter Cundall, has become widely used for the modeling of a rock mass, including its deformation, damage, fracturing and stability. DEM modeling of the coupled thermo-hydro-mechanical processes in fractured rock masses can provide some unique insights, to say the least, for better understanding of those complex issues.The authors of this book have participated in various projects involving DEM modeling of coupled thermo-hydro-mechanical processes during treatment of a rock mass by fluid injection and/or extraction and have provided consulting services to some of the largest oil-and-gas companies in the world. The breadth and depth of our engineering expertise are reflected by its successful applications in the major unconventional plays in the world, including Permian, Marcellus, Bakken, Eagle Ford, Horn River, Chicontepec, Sichuan, Ordos and many more. The unique combination of the state-of-the-art numerical modeling techniques with state-of-the-practice engineering applications makes the presented material relevant and valuable for engineering practice. We believe that it is beneficial to share the advances on this subject and promote some further development.

Covariance and Gauge Invariance in Continuum Physics: Application to Mechanics, Gravitation, and Electromagnetism (Progress in Mathematical Physics #73)
by Lalaonirina R. RakotomananaThis book presents a Lagrangian approach model to formulate various fields of continuum physics, ranging from gradient continuum elasticity to relativistic gravito-electromagnetism. It extends the classical theories based on Riemann geometry to Riemann-Cartan geometry, and then describes non-homogeneous continuum and spacetime with torsion in Einstein-Cartan relativistic gravitation. It investigates two aspects of invariance of the Lagrangian: covariance of formulation following the method of Lovelock and Rund, and gauge invariance where the active diffeomorphism invariance is considered by using local Poincaré gauge theory according to the Utiyama method. Further, it develops various extensions of strain gradient continuum elasticity, relativistic gravitation and electromagnetism when the torsion field of the Riemann-Cartan continuum is not equal to zero. Lastly, it derives heterogeneous wave propagation equations within twisted and curved manifolds and proposes a relation between electromagnetic potential and torsion tensor.
Cover Crops and Soil Ecosystem Services (ASA, CSSA, and SSSA Books #196)
by Humberto BlancoCover Crops and Soil Ecosystem Services A comprehensive resource on cover crops and their role in soil ecosystems Cover crops are a reemerging strategy to improve and maintain the services that soils provide. They can have an enormous affect on agricultural outcomes, preventing soil erosion, restoring vital soil nutrients, sequestering C from the atmosphere, and more. The successful management and use of cover crops is therefore critical to ensure soil ecosystem services are maintained or improved not only to meet our demands for food, fuel, fiber, and feed but also to reduce pollution and improve the soil. Cover Crops and Soil Ecosystem Services provides a heavily researched and highly readable introduction to cover crops and their role in soil ecosystems. It ranges from a detailed discussion of cover crop biomass production to a thorough treatment of soil ecosystems and their vulnerabilities. The result is an essential guide to a critical area of agricultural science. Cover Crops and Soil Ecosystem Services readers will also find: Detailed treatment of cover crop biomass production, soil erosion, greenhouse gas fluxes, nitrate leaching, soil C sequestration, and more Discussion of emerging issues, including extreme weather events and the economics of cover crop farming Wide-ranging summaries of interdisciplinary soil and cover crop research Cover Crops and Soil Ecosystem Services is a useful reference for students and researchers at all levels of study relating to cover crop agriculture.
Cover Crops and Sustainable Agriculture
by Rafiq Islam and Bradford ShermanThis book will not serve as the "encyclopedia of cover crop management," but it’s close. The benefits of a wide range of individual cover crops and blends/mixes for specific agronomic crop rotations and geographic locations are included. Descriptions, photographs, and illustrations show how cover crops look in the field, including plant height, leaf architecture, and rooting patterns. Long term benefits are described for soil health, soil structure, water quality, nutrient contributions, soil biodiversity, air quality and climate change. In addition to the "whys" of cover crop use, the book includes details on the "hows:" how to choose cover crops for specific applications and locations; how (and when) to plant; how to manage and maintain the cover for maximum benefit; and how and when to terminate. Planting options include: drilling/planting between rows of an agronomic crop at planting time, or when the crop is short (i.e. corn in early June); "aerial" seeding with an airplane or high-clearance machine shortly before the crop reaches maturity; and drilling/planting immediately after harvest of the agronomic crop. Selected cover crops (blends) can help with pest and disease management. Cover crops are an economic input with an expected return on investment, similar to pesticides and fertilizer. As part of a continuous no-till system, cover crops provide long-term biological, chemical and structural benefits. The resulting increase in soil organic matter means the agronomic crop yields benefit from better water infiltration and water holding capacity, greater availability of nitrogen and other nutrients, deeper rooting, and increased soil microbial activity in the root zone.
Cover Crops for Sustainable Farming
by Eric JustesThis study, based on a literature review and simulations, shows the efficiency of cover crops at catching nitrate in most agriculture situations. It also analyzes both the negative impacts they can have and the ecosystem services they can provide. The introduction of a cover crop between two main crops helps catch the soil mineral nitrogen before the period of drainage and consequently reduces nitrate leaching and nitrate concentration in the drainage water. This study allows quantifying the efficiency of cover crops at catching nitrate and optimizing their implantation conditions over a large range of French pedoclimatic conditions. The presence of high nitrate levels in surface and ground waters, due to excessive nitrogen fertilization and natural production of nitrate by soil organic matter mineralization, is a double challenge for public health and environment protection.

Covert Radio Agents, 1939–1945: Signals From Behind Enemy Lines
by David Hebditch“A treasure of a book…An authentic adventure saga [and] a very human story generously seasoned with ingenuity, technology and hardy individualism.” —K9YA TelegraphIncludes photos and mapsClandestine radio operators had one of the most dangerous jobs of World War II. Those in Nazi-occupied Europe for the SOE, MI6, and OSS had a life expectancy of just six weeks. In the Gilbert Islands, the Japanese decapitated seventeen New Zealand coastwatchers.These highly skilled agents’ main tasks were to maintain regular contact with their home base and pass vital intelligence back. As this meticulously researched book reveals, many operators did more than that. Norwegian Odd Starheim hijacked a ship and sailed it to the Shetlands. In the Solomon Islands Jack Read and Paul Mason warned the defenders of Guadalcanal about incoming enemy air raids, giving American fighters a chance to inflict irreversible damage on the Japanese Air Force. In 1944 Arthur Brown was central to Operation Jedburgh’s success delaying the arrival of the SS Das Reich armored division at the Normandy beachheads. The author also explains in layman’s terms the technology of 1940s radios and the ingenious codes used.Most importantly, Covert Radio Agents tells the dramatic human stories of these gallant behind-the-lines radio agents. Who were they? How were they trained? How did they survive against the odds? This is a highly informative and uplifting history of World War II’s unsung heroes.

Cowed: The Hidden Impact of 93 Million Cows on America’s Health, Economy, Politics, Culture, and Environment
by Denis Hayes Gail Boyer HayesFrom leading ecology advocates, a revealing look at our dependence on cows and a passionate appeal for sustainable living. In Cowed, globally recognized environmentalists Denis and Gail Boyer Hayes offer a revealing analysis of how our beneficial, centuries-old relationship with bovines has evolved into one that now endangers us. Long ago, cows provided food and labor to settlers taming the wild frontier and helped the loggers, ranchers, and farmers who shaped the country's landscape. Our society is built on the backs of bovines who indelibly stamped our culture, politics, and economics. But our national herd has doubled in size over the past hundred years to 93 million, with devastating consequences for the country's soil and water. Our love affair with dairy and hamburgers doesn't help either: eating one pound of beef produces a greater carbon footprint than burning a gallon of gasoline. Denis and Gail Hayes begin their story by tracing the co-evolution of cows and humans, starting with majestic horned aurochs, before taking us through the birth of today's feedlot farms and the threat of mad cow disease. The authors show how cattle farming today has depleted America's largest aquifer, created festering lagoons of animal waste, and drastically increased methane production. In their quest to find fresh solutions to our bovine problem, the authors take us to farms across the country from Vermont to Washington. They visit worm ranchers who compost cow waste, learn that feeding cows oregano yields surprising benefits, talk to sustainable farmers who care for their cows while contributing to their communities, and point toward a future in which we eat less, but better, beef. In a deeply researched, engagingly personal narrative, Denis and Gail Hayes provide a glimpse into what we can do now to provide a better future for cows, humans, and the world we inhabit. They show how our relationship with cows is part of the story of America itself.

Cows Save the Planet: And Other Improbable Ways of Restoring Soil to Heal the Earth
by Judith D. SchwartzIn Cows Save the Planet, journalist Judith D. Schwartz looks at soil as a crucible for our many overlapping environmental, economic, and social crises.Schwartz reveals that for many of these problems—climate change, desertification, biodiversity loss, droughts, floods, wildfires, rural poverty, malnutrition, and obesity—there are positive, alternative scenarios to the degradation and devastation we face. In each case, our ability to turn these crises into opportunities depends on how we treat the soil.Drawing on the work of thinkers and doers, renegade scientists and institutional whistleblowers from around the world, Schwartz challenges much of the conventional thinking about global warming and other problems. For example, land can suffer from undergrazing as well as overgrazing, since certain landscapes, such as grasslands, require the disturbance from livestock to thrive. Regarding climate, when we focus on carbon dioxide, we neglect the central role of water in soil—&”green water&”—in temperature regulation. And much of the carbon dioxide that burdens the atmosphere is not the result of fuel emissions, but from agriculture; returning carbon to the soil not only reduces carbon dioxide levels but also enhances soil fertility.Cows Save the Planet is at once a primer on soil&’s pivotal role in our ecology and economy, a call to action, and an antidote to the despair that environmental news so often leaves us with.&“Judith Schwartz takes a fascinating look at the world right beneath our feet. Cows Save the Planet is a surprising, informative, and ultimately hopeful book.&”—Elizabeth Kolbert, Pulitzer Prize-winning author of The Sixth Extinction

Cracking Control on Early-Age Concrete Through Internal Curing
by Dejian ShenThis monograph is written based on the author's research on the assessment, control, and repair of cracking of early-age concrete in the recent decade. The technique of internal curing for increasing cracking resistance of early-age concrete is further developed through experimental and theoretical research. It establishes models for predicting the internal relative humidity and autogenous shrinkage of internally cured concrete at early age; reveals the variation law and mechanism of early-age tensile creep of internally cured concrete; and explores the variation law and mechanism of early-age cracking resistance of internally cured concrete under continuous restrained condition or uniaxial restrained condition. It is designed as a reference work for professionals or practitioners and a textbook for undergraduates or postgraduates. As such, this book provides valuable knowledge, useful methods, and practical experience that can be considered in the field of concrete cracking control.
Cracking Hitler's Atlantic Wall: The 1st Assault Brigade Royal Engineers on D-Day
by Richard C AndersonA military historian analyzes the ingenious WWII tanks known as Hobart&’s Funnies, detailing their development and their role in the D-Day campaign. When the British and Canadians landed in Normandy on June 6, 1944, they were accompanied by specialized armored vehicles designed to remove German obstacles and mines. Developed by the Royal Engineers, these tanks known as Hobart's Funnies featured a range of ingenious innovations, from carpet-laying and bridge-laying devices to a giant 290-millimeter mortar. Examining these vehicles from technical development to combat deployment, military historian Richard C. Anderson Jr. gives a minute-by-minute account of D-Day's early hours on Sword, Juno, and Gold Beaches—the critical moments when success hinged on the assault engineers&’ ability to clear a path or breach the seawall. Anderson also describes the events on Omaha and Utah Beaches, where U.S. troops, despite being offered these vehicles, stormed ashore without them. Through careful comparison of conditions and outcomes, Anderson assesses the vehicles&’ performance and impact on D-Day's successes and failures.
