Event Mixed Company III, a 500-ton TNT surface charge, was detonated on 13 November 1972 at Grand Junction, Colorado, near Glade Park. Project LN305, 'Effectiveness of Craters as Barriers to Mobility, ' was included in the program of projects sponsored by the United States pertaining to the event. The objective of Project LN305 was to determine: (1) the degree to which a crater and its associated ejecta field constitute a physical barrier to the movement of military vehicles, and (2) if the crater was impassable, the amount of engineering effort required to construct a passable route for the vehicles under consideration. Five terrain units (including the original surface) in the crater area were delineated as significant to ground mobility and were described in terms of soil strength, soil moisture content, surface configuration, and ejecta depth. Go-no go mobility tests were conducted with two tracked vehicles (an M113A1 armored personnel carrier and an M60A1 tank) and one wheeled vehicle (an M561 1-1/4-ton cargo carrier). The vehicles were operated easily in all the terrain units except terrain unit 4, the crater wall. The crater wall of test lane B was impassable for all the vehicles until the steep slope (66%) was graded to a 47% slope. The grading required 12 minutes with a TD 20 bulldozer. All vehicles experienced approximately the same degree of difficulty negotiating the crater walls. (Author).

The first comprehensive monograph in blast cleaning technology, this book provides a comprehensive review of the technology, with an emphasis on practical applications. The author first systematically and critically reviews the theory behind the technology. Next you’ll learn about the state of current blast cleaning, surface quality aspects, and the effects of blast cleaning on the performance of applied coatings. You’ll also discover many of today’s cutting-edge applications, including micro-machining, polishing, maintenance, and surface preparation for coating applications. Finally, the author describes recent advanced applications in the machining industry, including blast cleaning-assisted laser milling.

This book gathers the proceedings of the 30th Scientific-Experts Conference of Agriculture and Food Industry, held on September 26-27, 2019, in Sarajevo, Bosnia and Herzegovina. It reports on the application of innovative technologies in food sciences and agriculture, and covers research in plant and animal production, agricultural economics and food production. Further, the book discusses key social and environmental issues, and proposes answers to current challenges. The conference was jointly organized by the Faculty of Agriculture and Food Sciences of the University of Sarajevo, Bosnia and Herzegovina, the Faculty of Agriculture of Ege University, Turkey, the Bosnia and Herzegovina Medical and Biological Engineering Society, and the Faculty of Agriculture of the University of Belgrade, Serbia. The proceedings offer a timely snapshot of cutting-edge, multidisciplinary research and developments in modern agriculture. As such, they address the needs of researchers and professionals, agricultural companies, food producers, and regulatory and food safety agencies.
