Book Description
Excerpt from Debarking Chipped Logging Residues: Technique and Potential Impact The compression debarker consists of two steel rolls. By adjusting the position of roll stops, a predetermined nip spacing can be set between the rolls. Two hydraulic cylinders hold the adjustment roll in place and control the degree of compression to which the chips are subjected. The surfaces of the two compression rolls can be varied. In the initial tests conducted with the Intermountain species, one smooth and one knurled roll were used.

Book Description
Wood chippers are machines intended for the reduction of wood and brush into small chips for the purpose of disposal. Although uncommon, these machines have been used as tools of homicide concealment through mechanical reduction of human remains following dismemberment. In light of this use and limited prior research, it is important for forensic anthropologists to understand the mechanisms of skeletal trauma and distribution patterns. In this study, Sus scrofa domesticus remains were utilized as a proxy for human remains and fed through a small commercial wood chipper. Observations following reduction included a large amount of associated hard and soft tissue with small bone fragments being embedded in large swatches of skin and muscle tissue. Skeletal trauma includes a wide array of macroscopic and microscopic sharp-blunt force trauma characteristics resulting from contact with the blade and the feed roller. This research provides experimental evidence of sharp-blunt trauma characteristics caused by wood chippers, a distribution pattern expected from a disc-type wood chipper reduction, as well as natural and human-enacted methods of concealment. This study should be considered when searching for dispersed remains resulting from cases of suspected wood chipper reduction.

Book Description
The first-ever book on this subject establishes a rigid, transparent and useful methodology for investigating the material metabolism of anthropogenic systems. Using Material Flow Analysis (MFA), the main sources, flows, stocks, and emissions of man-made and natural materials can be determined. By demonstrating the application of MFA, this book reveals how resources can be conserved and the environment protected within complex systems. The fourteen case studies presented exemplify the potential for MFA to contribute to sustainable materials management. Exercises throughout the book deepen comprehension and expertise. The authors have had success in applying MFA to various fields, and now promote the use of MFA so that future engineers and planners have a common method for solving resource-oriented problems.

Book Description
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.
