Rock Blasting and Explosives Engineering covers the practical engineering aspects of many different kinds of rock blasting. It includes a thorough analysis of the cost of the entire process of tunneling by drilling and blasting in comparison with full-face boring. Also covered are the fundamental sciences of rock mass and material strength, the thermal decomposition, burning, shock initiation, and detonation behavior of commercial and military explosives, and systems for charging explosives into drillholes. Functional descriptions of all current detonators and initiation systems are provided. The book includes chapters on flyrock, toxic fumes, the safety of explosives, and even explosives applied in metal working as a fine art. Fundamental in its approach, the text is based on the practical industrial experience of its authors. It is supported by an abundance of tables, diagrams, and figures. This combined textbook and handbook provides students, practitioners, and researchers in mining, mechanical, building construction, geological, and petroleum engineering with a source from which to gain a thorough understanding of the constructive use of explosives.
This remarkable volume presents the first revision to the classification system of diamond-bearing rocks in over eighty years. Presenting the latest mineralogical data, this book offers a detailed description of the mineralogy and geochemistry of kimberlites, orangeites, and lamproites. Several hundred new analyses of minerals in orangeites are included. This volume follows the publication of Kimberlites, by R.H. Mitchell, and Petrology of Lamproites, by R.H. Mitchell and S.C. Bergman, concluding the trilogy.
Visionary Railroader chronicles the life of a key figure in the history of rail travel in the United States. As president of the Baltimore & Ohio Railroad, Jervis Langdon Jr. had the opportunity to put progressive concepts into practice. In 1964, Langdon took charge of the Rock Island, and by the time he left in 1970, he had spearheaded major improvements for this struggling carrier. The same year, he became lead trustee for the bankrupt Penn Central and three years later assumed the presidency. From his role in passing the Regional Rail Reorganization Act of 1973 to his work on creating the quasi-public Conrail, Visionary Railroader examines the impact of Langdon's active life with clear text, unique representations of media of the day, and select family photos.
Natural disasters destroy more property and kill more people with each passing year. Volcanic eruptions, earthquakes, hurricanes, tsunamis, floods, landslides, fires and other natural events are becoming more frequent and their consequences more devastating. Del Moral and Walker provide a comprehensive summary of the diverse ways in which natural disasters disrupt humanity and how humans cope. Burgeoning human numbers, shrinking resources and intensification of the consequences of natural disasters have produced a crisis of unparalleled proportions. Through this detailed study, the authors provide a template for improving restoration to show how relatively simple approaches can enhance both human well-being and that of the other species on the planet. This book will appeal to ecologists, land managers as well as anyone curious about the natural world and natural disasters.

Prehistoric life is the archive of evolution preserved in thefossil record. This book focuses on the meaning andsignificance of that archive and is designed for introductorycollege science students, including non-science majors, enrolled insurvey courses emphasizing paleontology, geology and biology. From the origins of animals to the evolution of rap music, fromancient mass extinctions to the current biodiversity crisis, andfrom the Snowball Earth to present day climate change this bookcovers it, with an eye towards showing how past life on Earth putsthe modern world into its proper context. The history of life andthe patterns and processes of evolution are especially emphasized,as are the interconnections between our planet, its climate system,and its varied life forms. The book does not just describe thehistory of life, but uses actual examples from life’s historyto illustrate important concepts and theories.
In this book, the first dedicated entirely to the petrology of lamproites and their relationships to other potassium-rich rocks, the objective of the authors is to provide a comprehensive critical review of the occurrence, mineralogy, geochemistry, and petrogenesis of the clan. Although lamproites represent one of the rarest of all rock types, they are both economically and scientifically important and we believe the time is ripe for a review of the advances made in their petrology over the past two decades. Many of these advances stem from the recognition of diamond-bearing lamproites in Western Australia and the reclassification of several anomalous diamond-bearing kim berlites as lamproites. Consequently lamproites, previously of interest only to a small number of mineralogists specializing in exotica outside the mainstream of igneous petrol ogy, have become prime targets for diamond exploration on a worldwide basis. Contemporaneously with these developments, petrologists realized that lamproites possess isotopic signatures complementary to those of midoceanic ridge basalts, alkali basalts, kimberlites, and other mantle-derived melts. These isotopic studies provided new insights into the long-term development of the mantle by suggesting that the source regions of lamproites were metasomatically enriched in light rare earth and other incompatible elements up to 1-2 Ga prior to the melting events leading to generation of the magma.
This is the first systematic attempt to survey in detail the archaeological evidence for the crafts and craftsmanship of the Sumerians, Babylonians, and Assyrians in ancient Mesopotamia, covering the period ca. 8000-300 B.C.E. As creators of some of the earliest farming and urban communities known to us, these people were among the first pioneers of many crafts and skills that remain fundamental to modern ways of life. Many of the raw materials for crafts had to be imported from outside the river valley of the Tigris and Euphrates, providing an unusually sensitive indicator of the commercial and cultural contacts of Mesopotamia. In this book, Dr. Moorey reviews briefly the textual evidence, and then goes on to examine in detail the material evidence for a wide range of crafts using stones, both common and ornamental, animal products--from hippopotamus ivory to ostrich egg-shells--ceramics, glazed materials and glass, metals, and building materials. With a comprehensive bibliography, this will be a key work of reference for archaeologists and those interested in the early history of crafts and technology, as well as for specialist historians of the ancient Near East.
To many people, the suggestion that a kangaroo could live up a tree is fantasy. Yet, in the rainforests of Far North Queensland and New Guinea, there are extraordinary kangaroos that do just that. Many aspects of these marsupials' anatomy and biology suggest a terrestrial kangaroo ancestor. Yet no one has, so far, come forward with a convincing explanation of how, why and when mammals that was so superbly adapted for life on the ground should end up back in the trees. This book reviews the natural history and biology of tree-kangaroos from the time of their first discovery by Europeans in the jungles of West Papua in 1826 right up to the present day, covering the latest research being conducted in Australian and New Guinea. Combining information from a number of disparate disciplines, the author sets forth the first explanation of this apparent evolutionary conundrum. Features * Provides a fascinating and readable account of an unusual evolutionary conundrum * Written by a field biologist with more than a decade's experience working with tree-kangaroos

Tis text has resulted from some forty years of experience during which the author has puzzled over the meaning of ore textures. Te learning process has been slow and is still incomplete. Te bemusement began directly upon leaving the academic confnes, which in retrospect lef one keen young geologist very ill-equipped to interpret the mineralising process via feld or hand lens style observation of the rocks. Enlightenment has proceeded via a series of events:- 1. Te slow process of feld observation as an industry-based mine and exploration geologist. 2. Te opportunity to visit numerous diferent styles of ore deposit both as an academic and consultant. 3. Te need to answer questions from several generations of enquiring students. 4. Te privilege of being able to conduct research. 5. Te good fortune to be associated with a few top class economic geologists who actually knew what they were doing! Professor Willard C. Lacy deserves the most credit for quietly demonstrating the value of frst principles concerning fuid channelways, combined with an ability to look properly at the t- tures. Despite rapid technological advances this skill remains fundamental both to the practi- ing exploration geologist and to the academic researcher who is interested in understanding ore forming processes. Te fve volumes comprising this presentation were originally compiled individually over a period of eleven years, and aimed to progressively guide the observer though the principles of recogn-i tion concerning infll, alteration, overprinting, and fnally to ore-related breccias.
Even though the First Amendment of the U.S. Constitution grants freedom of speech and freedom of the press, laws and regulations governing media frequently evolve as the media themselves do. As a result, it is often a challenge to keep pace with new laws and regulations.Electronic Media Law is a comprehensive, up-to-date textbook on the constantly changing and often complex world of electronic media law. Author Roger L. Sadler examines the laws, regulations, and court rulings affecting broadcasting, cable, satellite, and cyberspace. The book also looks at cases from the print media and general First Amendment law, because they often contain important concepts that are relevant to the electronic media. Electronic Media Law is written for mass media students, not for future lawyers, so the text is straightforward and explains "legalese." The author covers First Amendment law, political broadcasting rules, broadcast content regulations, FCC rules for station operations, cable regulation, media ownership rules, media liability lawsuits, intrusive newsgathering methods, media restrictions during wartime, libel, privacy, copyright, advertising law, freedom of information, cameras in the court, and privilege.Key Features Provides an easy-to-use format of chapter categories and sections that facilitate research on individual topics Frequently Asked Questions highlight important points from cases Explains complex, legal concepts in basic terms that give students the foundation for further studies in electronic media law Electronic Media Law provides an understanding of the First Amendment and the American legal system with an emphasis on the electronic media. It is an excellent textbook for undergraduate and graduate students studying broadcast law and media law.
