Book Description
This book has following unique features that distinguish it from other works from the same area: 1) Investigates the influence of fissure geometry on strength failure and crack evolution behaviour of real rock material; 2) Analyzes the effect of pre-experiment high-temperature treatment on fracture mechanical behaviour of rock material with a single fissure or two parallel fissures; 3) Compares quantitatively simulated results using discrete element modelling and experimental results of fracture mechanical behaviour of rock material with two fissures; 4) Constructs the relationship between crack evolution processes and acoustic emission distribution of pre-fissured rock material under entire deformation; and 5) Discusses the crack evolution mechanism of pre-fissured rock material with respect to different confining pressures. This book can become the reference for technicians in the field of geotechnical engineering, mining engineering and geology engineering. At the same time, this book can be regarded as a good reference for scientific researchers carrying out fissured rock mechanics and correlated specialties.

NEW YORK TIMES BESTSELLER NEW YORK TIMES EDITORS' CHOICE O MAGAZINE BEST SUMMER BOOK Told by the man who lived it, The Cook Up is a riveting look inside the Baltimore drug trade as portrayed in the hit HBO series, The Wire. The smartest kid on his block in East Baltimore, D. was certain he would escape the life of drugs, decadence, and violence that had surrounded him since birth. But when his brother Devin is shot-only days after D. receives notice that he's been accepted into Georgetown University-the plans for his life are exploded, and he takes up the mantel of his brother's crack empire. D. succeeds in cultivating the family business, but when he meets a woman unlike any he's known before, his priorities are once more put into question. Equally terrifying and hilarious, inspiring and heartbreaking, D.'s story offers a rare glimpse into the mentality of a person who has escaped many hells.

2020 Banff Mountain Book Competition Finalist in Guidebooks Crack climbing is a highly technical form of movement in which climbers position their hands, feet, and even their entire body in cracks to make upward progress on rock. An advocate for the sport’s aesthetic lines, physicality, and technical know-how, author Pete Whittaker teaches more than sixty Crack School Masterclasses each year and was featured in the popular climbing film Wide Boyz. This detailed and comprehensive guide teaches step-by-step techniques and tips, including for: Jamming (finger, hand, fist, foot, arm, leg, body) Crack types (chimneys, liebacks, underclings, roof cracks) How to safely lead and place protection Efficient positioning and movement Strength recovery while climbing

Book Description
The analysis of crack problems through fracture mechanics has been applied to the study of materials such as glass, metals and ceramics because relatively simple fracture criteria describe the failure of these materials. The increased attention paid to experimental rock fracture mechanics has led to major contributions to the solving of geophysical problems. The text presents a concise treatment of the physics and mathematics of a representative selection of problems from areas such as earthquake mechanics and prediction, hydraulic fracturing, hot dry rock geothermal energy, fault mechanics, and dynamic fragmentation.

Book Description
An oral history in the vein of Please Kill Me Leftöver Crack is a band of drug abusing, dumpster diving, cop-hating, queer positive, pro-choice, crust punks that successfully blend ska-punk, pop, hip-hop and death metal genres. They've been banned from clubs, states and counties and kicked off multiple record labels. They've received teen-idol adoration and death threats from their fans. They've played benefits for a multitude of causes while leaving a trail of destruction in their wake. But, if you dig below the crusty, black metal-patch encased surface, you'll find a contemplative, nuanced band that, quite literally, permanently changed the punk rock community. By combining catchy ska-punk with lyrics that referenced political theorist Michael Parenti, drug usage, and suicide, the band formed a unique mélange that was both provocative and challenging. In fact, the band's hooks were so sharp that after releasing their debut LP, Mediocre Generica, an entire culture of "Crack City Rockers" grew around the band, pushing the youth towards both the positive and negative aspects of extreme punk rock. Of course, being the combustible band that they are, the band has gotten involved in its far share of fiascoes: full-scale riots in Phoenix and NYC, getting punched out by their own fans, showing up to tour Florida with machetes after receiving death threats from the local gang. Architects of Self-Destruction: An Oral History of Leftöver Crack traces the band's entire history by speaking to the band members themselves, fellow musicians, their fans, and of course, those that still hold a grudge against the LoC... FYI, that's a lot of people.

Book Description
First published in 1962, David E. Miller’s award-winning work on the Hole-in-the-Rock episode was arguably his greatest achievement as a historian. One of the great set-pieces of Mormon history, the San Juan Mission had become clouded by myth and hagiography when Miller first became attracted to its study in the 1950s, and few reliable sources were at that time available. Not content with exhausting archival material, Miller contacted all locatable descendants of the members of the original party, and thereby brought to light a great number of previously unexploited sources. The Hole-in-the-Rock study achieved additional depth from his intimate knowledge of the actual trail acquired on repeated traverses by Jeep and on foot. A member of the LDS Church, Miller wrote of the Mormons with sympathy and understanding, but with a commitment as well to the critical standards of the historical profession. A must-read for anyone interested in American History.

Book Description
The international bestselling author of The Professor and the Madman and Krakatoa vividly brings to life the 1906San Francisco Earthquake that leveled a city symbolic of America's relentless western expansion. Simon Winchester has also fashioned an enthralling and informative informative look at the tumultuous subterranean world that produces earthquakes, the planet's most sudden and destructive force. In the early morning hours of April 18, 1906, San Francisco and a string of towns to its north-northwest and the south-southeast were overcome by an enormous shaking that was compounded by the violent shocks of an earthquake, registering 8.25 on the Richter scale. The quake resulted from a rupture in a part of the San Andreas fault, which lies underneath the earth's surface along the northern coast of California. Lasting little more than a minute, the earthquake wrecked 490 blocks, toppled a total of 25,000 buildings, broke open gas mains, cut off electric power lines throughout the Bay area, and effectively destroyed the gold rush capital that had stood there for a half century. Perhaps more significant than the tremors and rumbling, which affected a swatch of California more than 200 miles long, were the fires that took over the city for three days, leaving chaos and horror in its wake. The human tragedy included the deaths of upwards of 700 people, with more than 250,000 left homeless. It was perhaps the worst natural disaster in the history of the United States. Simon Winchester brings his inimitable storytelling abilities -- as well as his unique understanding of geology -- to this extraordinary event, exploring not only what happened in northern California in 1906 but what we have learned since about the geological underpinnings that caused the earthquake in the first place. But his achievement is even greater: he positions the quake's significance along the earth's geological timeline and shows the effect it had on the rest of twentieth-century California and American history. A Crack in the Edge of the World is the definitive account of the San Francisco earthquake. It is also a fascinating exploration of a legendary event that changed the way we look at the planet on which we live.
