Download or read book The Ash Warriors written by C. R. Anderegg and published by Department of the Air Force. This book was released on 2000 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: In November 1991 the American flag was lowered for the last time at Clark Air Base in the Philippines. This act brought to an end American military presence in the Philippines that extended back over 90 years. It also represented the final act in a drama that began with the initial rumblings in April of that year of the Mount inatubo volcano, located about nine miles to the east of Clark. This book tells the remarkable story of the men and women of the Clark community and their ordeal in planning for and carrying out their evacuation from Clark in face of the impending volcanic activity. It documents the actions of those who remained on the base during the series of Mount Pinatubo' s eruptions, and the packing out of the base during the subsequent months. This is the story of the Ash Warriors, those Air Force men and women who carried out their mission in the face of an incredible series of natural disasters, including volcanic eruption, flood, typhoons, and earthquakes, all of which plagued Clark and the surrounding areas during June and July 1991.
Download or read book Irrigation Fundamentals written by George H. Hargreaves and published by Water Resources Publication. This book was released on 1998 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: IRRIGATION FUNDAMENTALS is a comprehensive text on the basic principles and practices of applied agricultural irrigation. Written over a period of more than 10 years, it is based on the authors'' extensive experience in farming, consulting, research, teaching, and other related agricultural activities. The book is for use by teachers of introductory courses in irrigation, farmers who have some basic technical knowledge, and for administrators who need a general understanding of irrigation as an aid for policy decisions in water resource development and planning. Various factors that influence crop yield and production including climate, fertility, water, drainage, and agronomic practices are addressed. The various irrigation methods such as border, basin, contour, furrow, sub, sprinkle, and drip or trickle are described; and conditions are given for selection of the appropriate method to use. Recent developments and new technology are included herein when they have obvious practical applications, but for the most part the material presented in this book is based on well established principles and practices. Much of the content is very practical and much is essentially nontechnical. Nevertheless, some of the material covered in this book goes beyond the basic concepts in an attempt to better describe the relationships and techniques employed by irrigation scientists and irrigation engineers.From the Preface: The future of the world depends very much on how we manage natural resources. Since the year 1900 there has been a ninefold increase in global carbon emissions from burning fossil fuels, and the world population has increased about 3.7 times in this century. Vast areas of forests have been destroyed, and irrigated lands now produce 40% of the food supply. Due to depletion of groundwater reserves and an increase in population, irrigated area per capita is declining. Consequently, the irrigation of additional alluvial lands is a strategic necessity for all of humankind. Much of the alluvial lands cannot be made productive without prior development of water resources through flood control, drainage, and irrigation. The production of electricity through hydropower and the production of alcohol fuel from irrigated crops, as has been practiced for many years in Brazil, can slow the increase in carbon emissions. Such diverse developments are typically not separable; rather, they must be considered as integral parts of a comprehensive development plan. The conservation of natural resources and increasing productivity of irrigated lands are also strategic necessities. Much of the current technology is highly transferable and crop yields can be significantly increased on lands already under irrigation.The authors have worked in many countries in connection with resource inventories, teaching, and the planning, development and use of irrigation as a tool for increasing production and providing employment. They have written extensively and have been honored for their achievements. They have considerable experience with everything from primitive low-technology irrigation developments to highly developed irrigation in the USA and in dozens of countries around the world. Both of the authors have dedicated their careers to teaching, research, and consulting in agricultural irrigation and water resources development and planning. It is their hope and expectation that this book will provide incentives for investigating and documenting land and water resources, improving development, increasing crop yields, conserving resources, and improving the environment.

Download or read book Twentieth Century Building Materials written by Thomas C. Jester and published by Getty Publications. This book was released on 2014-08-01 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the concluding decades of the twentieth century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, gas stations and diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior’s National Park Service and first published in 1995. Now, this invaluable guide is being reissued—with a new preface by the book’s original editor. With more than 250 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminum, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume. The book is intended for a wide range of conservation professionals including architects, engineers, conservators, and material scientists engaged in the conservation of modern buildings, as well as scholars in related disciplines.

Available in PDF, EPUB and Kindle. Book excerpt: "Leading the way describes how the men and women of Air Force civil engineering have provided the basing that enabled the Air Force to fly, fight, and win. This book depicts how engineers built hundreds of bases during World Wars I and II, Korea, Vietnam, the Gulf War, and Operations Enduring Freedom and Iraqi Freedom. At the same time, these engineers operated and maintained a global network of enduring, peacetime bases. It describes the engineers' role in special projects such as the ballistic missile program, the Arctic early warning sites, and construction of the U.S. Air Force Academy. Using hundreds of sources, this detailed narrative tells the story of how civil engineers have been organized, trained, equipped, and employed for more than 100 years. From the beaches of Normandy to the mountains of Afghanistan, civil engineers have forged an unmatched record of success and built a solid foundation for today's Air Force."--Back cover.
