This book was released on 2012-12-06 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern forest products research had its start hardly fifty years ago. Today we are in a position to apply the title "wood science" to the field of wood technology that is based on scientific investigation, theoretical as well as experimental. It is this research that fosters new uses for wood as a raw material and that creates the foundation for new industries for the manufacture of wood-base materials such as plywood, laminated products, particle and fiber board and sand wich construction. Wood technology in its broadest sense combines the disciplines of wood anatomy, biology, chemistry, physics and mechanical technology. It is through this interdisciplinary approach that progress has been made in wood seasoning, wood preservation methods, wood machining, surfacing and gluing, and in the many other processes applied in its utilization. In 1936 the senior author published a book entitled, "Technologie des Holzes", which was a first approach to a universal reference book on wood technology. The first edition of Volume I of the Textbook of Wood Technology, co-authored by H. P. BROWN, A. J. P AN SHIN , and C. C. FORSAITH, was published in 1948. An indication of the rapid development of this field can be gained from the fact that the second edition of "Technologie des Holzes und der Holzwerkstoffe", completely revised, was needed by 1951. It contains 2233 pages compared with the 764 pages of the 1936 edition.

Download or read book Do Not Feed the Bears written by Alice Wondrak Biel and published by University Press of Kansas. This book was released on 2006-03-16 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was a familiar sight at Yellowstone National Park: traffic backed up for miles as visitors fed bears from their cars. It may have been against the rules, but park officials were willing to turn a blind eye if it kept the public happy. But bear feeding eventually became too widespread and dangerous to everyone-including the bears-for the National Park Service (NPS) to allow it any longer. As one of the park's most beloved and enduring symbols, the Yellowstone bears have long been a flashpoint for controversy. Alice Wondrak Biel traces the evolution of their complex relationship with humans-from the creation of the first staged wildlife viewing areas to the present-and situates that relationship within the broader context of American cultural history. Early on, park bears were largely thought of as performers or surrogate pets and were routinely fed handouts from cars, as well as hotel garbage dumped at park-sanctioned "lunch counters for bears." But as these activities led to ever-greater numbers of tourist injuries, and of bears killed as a result, and as ideas about conservation and the NPS mission changed, the agency refashioned the bear's image from cute circus performer to dangerous wild animal and, eventually, to keystone inhabitant of a fragile ecosystem. Drawing on the history of recorded interactions with bears and providing telling photographs depicting the evolving bear-human relationship, Biel traces the reaction of park visitors to the NPS's efforts—from warnings by Yogi Bear (which few tourists took seriously) to the increasing promotion of key ecological issues and concerns. Ultimately, as the rules were enforced and tourist behavior dramatically shifted, the bears returned to a more natural state of existence. Biel's entertaining and informative account tracks this gradual "renaturalization" while also providing a cautionary tale about the need for careful negotiation at the complex nexus of tourists, bears, and all things wild.
