This book was released on 1977 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Yuma Proving Ground was visited to conduct a survey of the relative hardness of selected impact areas to establish the most suitable sites for a survivability test as part of DT II testing of 155mm XM718/741 Remote Anti-Armor Mine System (RAAMS). Soil/terrain data were collected at Z, R, Cain, and Adam Fields located along the north side of Poleline Road. Z and R Fields were located on nearly level, moderately dissected gravelly piedmont which had recently been graded and compacted to achieve a high strength within the compacted layer. Cain Field is located on a wash. The area is undulating and bare. Adam Field is located on predominantly gravelly undissected piedmont with some wash areas. The area is undulating and the brush vegetation was removed. The surface materials at the four impact areas visited are predominantly coarse-grained soils with some areas having large amounts of gravel and caliche. The soil was slightly moist and firm when sampled. The cone index ranged from 300 to 500 in the 0- to 6-in. layer, and the dynamic cone penetrometer blows per foot for the surface 12 in. ranged from 17 to 34. A comparison of calculated peak rigid body deceleration-impact velocity relation for selected surface materials revealed that the magnitude of the rigid body g forces that the RAAM can experience upon impact with various earth materials varies considerably.

Download or read book Desalination written by National Research Council and published by National Academies Press. This book was released on 2008-09-14 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been an exponential increase in desalination capacity both globally and nationally since 1960, fueled in part by growing concern for local water scarcity and made possible to a great extent by a major federal investment for desalination research and development. Traditional sources of supply are increasingly expensive, unavailable, or controversial, but desalination technology offers the potential to substantially reduce water scarcity by converting the almost inexhaustible supply of seawater and the apparently vast quantities of brackish groundwater into new sources of freshwater. Desalination assesses the state of the art in relevant desalination technologies, and factors such as cost and implementation challenges. It also describes reasonable long-term goals for advancing desalination technology, posits recommendations for action and research, estimates the funding necessary to support the proposed research agenda, and identifies appropriate roles for governmental and nongovernmental entities.

Download or read book Fundamentals of Geomorphology written by Richard John Huggett and published by Routledge. This book was released on 2011-03-15 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively revised, restructured, and updated edition continues to present an engaging and comprehensive introduction to the subject, exploring the world’s landforms from a broad systems perspective. It covers the basics of Earth surface forms and processes, while reflecting on the latest developments in the field. Fundamentals of Geomorphology begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss: structure: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; and landscape evolution, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change. This third edition has been fully updated to include a clearer initial explanation of the nature of geomorphology, of land surface process and form, and of land-surface change over different timescales. The text has been restructured to incorporate information on geomorphic materials and processes at more suitable points in the book. Finally, historical geomorphology has been integrated throughout the text to reflect the importance of history in all aspects of geomorphology. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries, and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, all in colour.

Download or read book Alternatives for Landmine Detection written by Jacqueline MacDonald Gibson and published by Rand Corporation. This book was released on 2003 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the rate that government and nongovernmental organizations are clearing existing landmines, it will take 450-500 years to rid the world of them. Concerned about the slow pace of demining, the Office of Science and Technology asked RAND to assess potential innovative technologies being explored and to project what funding would be required to foster the development of the more promising ones. The authors of this report suggest that the federal government undertake a research and development effort to develop a multisensor mine detection system over the next five to eight years.
