Download or read book The North American Mosaic written by Commission for Environmental Cooperation (Montréal, Québec). Secretariat and published by . This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.
Download or read book Prospecting and Exploration of Mineral Deposits written by M. Böhmer and published by Elsevier. This book was released on 2013-10-22 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the completely revised edition of a book which was published in 1978 and, such was its popularity, was sold out within two years. It was described as ``An excellent compilation and condensation of a vast field of literature and experience in economic geology. Clear illustrations, charts and tables punctuate the text material very nicely... Valuable for all economic geologists and resource developers.'' (Choice).The material is illustrated by 215 text figures and 76 tables, and is presented in two parts. The first part covers the geological background of the genesis of mineral deposits as a clue to new discoveries, and the methods of geological, geochemical and geophysical prospecting. The second part concerns sampling, documentation and computation of ore reserves and economic assessment of mineral deposits. This new edition has been very extensively revised and brought up to date. This holds true particularly for the chapters on geochemical and geophysical methods, the use of photo-geology and satellite imagery, oil and gas prospecting, exploration of underwater minerals, the application of the principles of global tectonics in prospecting for deposits, and the evaluation of reserves. These new or thoroughly revised chapters comprise almost half of the entire text.
Download or read book World Anthropologies written by Gustavo Lins Ribeiro and published by Routledge. This book was released on 2020-07-12 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its inception, anthropology's authority has been based on the assumption that it is a unified discipline emanating from the West. In an age of heightened globalization, anthropologists have failed to discuss consistently the current status of their practice and its mutations across the globe. World Anthropologies is the first book to provoke this conversation from various regions of the world in order to assess the diversity of relations between regional or national anthropologies and a contested, power-laden Western discourse. Can a planetary anthropology cope with both the 'provincial cosmopolitanism' of alternative anthropologies and the 'metropolitan provincialism' of hegemonic schools? How might the resulting 'world anthropologies' challenge the current panorama in which certain allegedly national anthropological traditions have more paradigmatic weight - and hence more power - than others? Critically examining the international dissemination of anthropology within and across national power fields, contributors address these questions and provide the outline for a veritable world anthropologies project.
Download or read book Intrepid Explorer written by J. David Lowell and published by University of Arizona Press. This book was released on 2014-10-03 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: When seven-year-old Dave Lowell was camped out at his father’s mine in the hills of southern Arizona in 1935, he knew he had found his calling. “Life couldn’t get any better than this,” he recalls. “I didn’t know what science was, but wisps of scientific thought were already working into my plan.” So began the legendary career of the engineer, geologist, explorer, and international businessman whose life is recounted in his own words in this captivating book. An Arizona native with family roots in territorial times, Lowell grew from modest beginnings on a ranch near Nogales to become a major world figure in the fields of minerals, mining, and economic geology. He has personally discovered more copper than anyone in history and has developed multibillion-dollar gold and copper mines that have changed the economies of nations. And although he has consulted for corporations in the field of mining, he has largely operated as an independent agent and explorer, the architect of his own path and success. His life’s story unfolds in four stages: his early education in his field, on-the-job learning at sites in the United States and Mexico, development of exploration strategies, and finally, the launch of his own enterprises and companies. Recurring themes in Lowell’s life include the strict personal, ethical, and tactical policies he requires of his colleagues; his devotion to his family; and his distaste for being away from the field in a corporate office, even to this day. The magnitude of Lowell’s overall success is evident in his list of mine discoveries, as well as in his scientific achievements and the enormous respect his friends and colleagues have had for him throughout his lengthy career, which he continues to zealously pursue.

Download or read book Fragments for a History of the Human Body written by Michel Feher and published by Zone Books. This book was released on 1989 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The first approach can be called vertical since what is explored here is the human body's relationship to the divine, to the bestial and to the machines that imitate or simulate it. The second approach covers the various junctures between the body's "outside" and "inside": it can therefore be called a "psychosomatic" approach, studying the manifestation - or production - of soul and the expression of emotions through the body's attitudes, and, on another level, the speculations inspired by cenesthesia, pain and death. Finally, the third approach ... brings into play the classical opposition between organ and function by showing how a certain organ or bodily substance can be used to justify or challenge the way human society functions ..." - foreword Part 3.
