Download or read book Dirt written by David R. Montgomery and published by Univ of California Press. This book was released on 2007-05-14 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dirt, soil, call it what you want—it's everywhere we go. It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.
Download or read book The Fertility Doctor written by Margaret Marsh and published by JHU Press. This book was released on 2008-10-31 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Louise Brown—the first baby conceived by in vitro fertilization—celebrates her 30th birthday, Margaret Marsh and Wanda Ronner tell the fascinating story of the man who first showed that human in vitro fertilization was possible. John Rock spent his career studying human reproduction. The first researcher to fertilize a human egg in vitro in the 1940s, he became the nation’s leading figure in the treatment of infertility, his clinic serving rich and poor alike. In the 1950s he joined forces with Gregory Pincus to develop oral contraceptives and in the 1960s enjoyed international celebrity for his promotion of the pill and his campaign to persuade the Catholic Church to accept it. Rock became a more controversial figure by the 1970s, as conservative Christians argued that his embryo studies were immoral and feminist activists contended that he had taken advantage of the clinic patients who had participated in these studies as research subjects. Marsh and Ronner’s nuanced account sheds light on the man behind the brilliant career. They tell the story of a directionless young man, a saloon keeper’s son, who began his working life as a timekeeper on a Guatemalan banana plantation and later became one of the most recognized figures of the twentieth century. They portray his medical practice from the perspective of his patients, who ranged from the wives of laborers to Hollywood film stars. The first scholars to have access to Rock’s personal papers, Marsh and Ronner offer a compelling look at a man whose work defined the reproductive revolution, with its dual developments in contraception and technologically assisted conception.

Download or read book Earth s Oldest Rocks written by Martin J. Van Kranendonk and published by Elsevier. This book was released on 2018-09-26 with total page 1114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth's Oldest Rocks, Second Edition, is the only single reference source for geological research of early Earth. This new edition is an up-to-date collection of scientific articles on all aspects of the early history of the Earth, from planetary accretion at 4.567 billion years ago (Ga), to the onset of modern-style plate tectonics at 3.2 Ga. Since the first edition was published, significant new advances have been made in our understanding of events and processes on early Earth that correspond with new advances in technology. The book includes contributions from over 100 authors, all of whom are experts in their respective fields. The research in this reference concentrates on what is directly gleaned from the existing rock record to understand how our planet formed and evolved during the planetary accretion phase, formation of the first crust, the changing dynamics of the mantle and style of tectonics, life's foothold and early development, and mineral deposits. It is an ideal resource for academics, students and the general public alike. - Advances in early Earth research since 2007 based primarily on evidence gleaned directly from the rock record - More than 50% of the chapters in this edition are new and the rest of the chapters are revised from the first edition, with more than 700 pages of new material - Comprehensive reviews of areas of ancient lithosphere from all over the world, and of crust-forming processes - New chapters on early solar system materials, composition of the ancient atmosphere-hydrosphere, and overviews of the oldest evidence of life on Earth, and modeling of early Earth tectonics

Download or read book Fission Track Thermochronology and its Application to Geology written by Marco G. Malusà and published by Springer. This book was released on 2018-07-14 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is focused on the basics of applying thermochronology to geological and tectonic problems, with the emphasis on fission-track thermochronology. It is conceived for relatively new practitioners to thermochronology, as well as scientists experienced in the various methods. The book is structured in two parts. Part I is devoted to the fundamentals of the fission-track method, to its integration with other geochronologic methods, and to the basic principles of statistics for fission-track dating and sedimentology applied to detrital thermochronology. Part I also includes the historical development of the technique and thoughts on future directions. Part II is devoted to the geological interpretation of the thermochronologic record. The thermal frame of reference and the different approaches for the interpretation of fission-track data within a geological framework of both basement and detrital studies are discussed in detail. Separate chapters demonstrate the application of fission-track thermochronology from various perspectives (e.g., tectonics, petrology, stratigraphy, hydrocarbon exploration, geomorphology), with other chapters on the application to basement rocks in orogens, passive continental margins and cratonic interiors, as well as various applications of detrital thermochronology.
