Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

This applications-oriented, introductory reference addresses numerous topics in the field of urban soil science.

Download or read book Pathogenesis of Idiopathic Scoliosis written by Masafumi Machida and published by Springer. This book was released on 2018-02-23 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive coverage of current topics in idiopathic scoliosis (IS). A three-dimensional deformity of the spine, the condition is characterized by lateral curvature combined with vertebral rotation. The primary lesion, however, lies in the median sagittal plane, taking the form of a lordosis. Although the clinical manifestations of scoliosis have been well documented, its cause and pathogenesis have not yet been determined. Research into what causes IS has focused on the structural elements of the spine, spinal musculature, collagenous structures, the endocrine system, the central nervous system, and genetics. Results of these studies have brought about a new perception of IS epiphenomena, but the main cause of IS remains unknown. Recently, several investigators have produced new hypotheses regarding the cause of IS using the developing techniques of genetics, biochemistry, and neurology. This book is a review of the various causative factors thus far proposed for IS and an introduction to the directions in which research is heading to determine the primary cause of IS.

Download or read book Transport in Plants I written by M.H. Zimmermann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.

Download or read book Geothermal Reservoir Engineering written by E. Okandan and published by Springer. This book was released on 2011-10-02 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the oil crisis of 1973, we suddenly became aware that fossil fuel resources are limited and will be exhausted soon if new alternatives are not put into use immediately. Conservation measures and extensive research on new sources of energy has eased the demand on fossil fuels, especially crude oil. Geothermal energy as an alternative; source had its share in this devel opment and electricity producing capacity increased from 700 to 4700 MWe during 1970 to 1985. Geothermal reservoir engineering emerged as an impor tant field in the assessment of geothermal sources. During the 25 years of its development, several areas were identified that needed further at tention for the correct description and interpretation of reservoir be havior. This fact as accepted by all operators is vital for the steady and continuous operation of power plants. During this NATO ASI, a detailed review of theory and field case his tories on geothermal reservoir engineering was presented. In understanding .the reservoir, conceptual models, natural state models, well bore measure ments, transient and tracer testing provide data which are indispensable. They are powerful tools in understanding reservoir behavior provided we know how to interpret them. During lectures the theory and practical applications of these interpretive methods were discussed.

Download or read book Defending the Land of the Jaguar written by Lane Simonian and published by University of Texas Press. This book was released on 1995 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexican conservationists have sometimes observed that it is difficult to find a country less interested in the conservation of its natural resources than is Mexico. Yet, despite a long history dedicated to the pursuit of development regardless of its environmental consequences, Mexico has an equally long, though much less developed and appreciated, tradition of environmental conservation. Lane Simonian here offers the first panoramic history of conservation in Mexico from pre-contact times to the current Mexican environmental movement. He explores the origins of conservation and environmental concerns in Mexico, the philosophies and endeavors of Mexican conservationists, and the enactment of important conservation laws and programs. This heretofore untold story, drawn from interviews with leading Mexican conservationists as well as archival research, will be important reading throughout the international community of activists, researchers, and concerned citizens interested in the intertwined issues of conservation and development.

Download or read book An Empty House written by Carlos Cerda and published by U of Nebraska Press. This book was released on 2003-01-01 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: A story of contemporary Chile by one of its most prominent novelists, An Empty House depicts the dissolution of an upper-middle-class family against a chilling background of exile, return, and discovery. The stark and moving narrative suggests the enormity of the horrors perpetrated in Chile over the last decades, horrors that resonate through the culture to this day. Cecilia and Manuel accept her father?s gift of a house, in hope of repairing their unraveling marriage along with the badly scarred building. Instead, the couple?s efforts expose the horrifying truth about the building?and reveal the subtle strands of complicity, responsibility, and indifference that bind them to each other, their country, and its dark past. ø With its deftly drawn characters, play of ideas, and vivid dialogue, An Empty House gives English-speaking readers a memorable portrait of Chile today: honest, brutally realistic, but with a redemptive touch of lyricism and hope.

Download or read book Emil du Bois Reymond written by Gabriel Finkelstein and published by MIT Press. This book was released on 2013-11-01 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: A biography of an important but largely forgotten nineteenth-century scientist whose work helped lay the foundation of modern neuroscience. Emil du Bois-Reymond is the most important forgotten intellectual of the nineteenth century. In his own time (1818–1896) du Bois-Reymond grew famous in his native Germany and beyond for his groundbreaking research in neuroscience and his provocative addresses on politics and culture. This biography by Gabriel Finkelstein draws on personal papers, published writings, and contemporary responses to tell the story of a major scientific figure. Du Bois-Reymond's discovery of the electrical transmission of nerve signals, his innovations in laboratory instrumentation, and his reductionist methodology all helped lay the foundations of modern neuroscience. In addition to describing the pioneering experiments that earned du Bois-Reymond a seat in the Prussian Academy of Sciences and a professorship at the University of Berlin, Finkelstein recounts du Bois-Reymond's family origins, private life, public service, and lasting influence. Du Bois-Reymond's public lectures made him a celebrity. In talks that touched on science, philosophy, history, and literature, he introduced Darwin to German students (triggering two days of debate in the Prussian parliament); asked, on the eve of the Franco-Prussian War, whether France had forfeited its right to exist; and proclaimed the mystery of consciousness, heralding the age of doubt. The first modern biography of du Bois-Reymond in any language, this book recovers an important chapter in the history of science, the history of ideas, and the history of Germany.

Download or read book Heavy Metals written by Wim Salomons and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Heavy Metals: Problems and Solutions" is divided into three sections dealing with basic geochemical processes, remediation and case studies. The basic geochemical processes are discussed with respect to mobility in the environment and impact as well as methods to derive guidelines for heavy metals. Remediation focuses on currently available methods to treat contaminated sediments and soils. In addition, it considers the concept of geochemical engineering for remediation of large areas contaminated by metals. A number of case studies of polluted sediments and soils and their environmental impact highlight the principles discussed in the first two sections.
