Book excerpt: Timber's strength, light weight, and energy-absorbing properties furnish features desirable for bridge construction. Timber is capable of supporting short-term overloads without adverse effects. Contrary to popular belief, large wood members provide good fire resistance qualities that meet or exceed those of other materials in severe fire exposures. From an economic standpoint, wood is competitive with other materials on a first-cost basis and shows advantages when life cycle costs are compared. Timber bridges can be constructed in virtually any weather conditions, without detriment to the material. Wood is not damaged by continuous freezing and thawing and resists harmful effects of de-icing agents, which cause deterioration in other bridge materials. Timber bridges do not require special equipment for installation and can normally be constructed without highly skilled labor. They also present a natural and aesthetically pleasing appearance, particularly in natural surroundings. The misconception that wood provides a short service life has plagued timber as a construction material. Although wood is susceptible to decay or insect attack under specific conditions, it is inherently a very durable material when protected from moisture. Many covered bridges built during the 19th century have lasted over 100 years because they were protected from direct exposure to the elements. In modem applications, it is seldom practical or economical to cover bridges; however, the use of wood preservatives has extended the life of wood used in exposed bridge applications. Using modem application techniques and preservative chemicals, wood can now be effectively protected from deterioration for periods of 50 years or longer. In addition, wood treated with preservatives requires little maintenance and no painting. Another misconception about wood as a bridge material is that its use is limited to minor structures of no appreciable size. This belief is probably based on the fact that trees for commercial timber are limited in size and are normally harvested before they reach maximum size. Although tree diameter limits the size of sawn lumber, the advent of glued-laminated timber (glulam) some 40 years ago provided designers with several compensating alternatives. Glulam, which is the most widely used modem timber bridge material, is manufactured by bonding sawn lumber laminations together with waterproof structural adhesives. Thus, glulam members are virtually unlimited in depth, width, and length and can be manufactured in a wide range of shapes. Glulam provides higher design strengths than sawn lumber and provides better utilization of the available timber resource by permitting the manufacture of large wood structural elements from smaller lumber sizes. Technological advances in laminating over the past four decades have further increased the suitability and performance of wood for modern highway bridge applications.

Book excerpt: Winner of the Christianity Today Book Award, Fiction In Eden Mine, the award-winning author of Black River examines the aftershocks of an act of domestic terrorism rooted in a small Montana town on the brink of abandonment, as it tears apart a family, tests the faith of a pastor and the loyalty of a sister, and mines the deep rifts that come when the reach of the government clashes with individual freedom If I stay here, Jo, I know you could find me. If you wanted to, you could find me. For generations, the Fabers have lived near Eden Mine, scraping by to keep ahold of their family's piece of Montana. Jo and her brother, Samuel, will be the last. Despite a long battle, their property has been seized by the state through eminent domain—something Samuel deems a government theft. As Jo packs, she hears news of a bombing. Samuel went off to find work in Wyoming that morning, but soon enough, it's clear that he's not gone but missing, last seen by a security camera near the district courthouse?now a crime scene?in Elk Fork. And the nine-year-old daughter of a pastor at a nearby church lies in critical condition. Can the person Jo loves and trusts most have done this terrible thing? Can she have missed the signs? The last time their family met violence, Jo lost her ability to walk. Samuel took care of her, outfitted their barn with special rigging so she could still ride their mule. What secrets has he been keeping? As Jo watches the pastor fight for his daughter, watches the authorities hunt down a criminal, she wrestles with an impossible choice: Must she tell them where Samuel might be? Must she choose between loyalty and justice? Between the brother she knows and the man he has become? A timely story of the tensions splintering families and communities all over this country, S.M. Hulse's Eden Mine is also a steady-eyed gaze into the ideals of the West and the legacies of violence, a moving account of faith in the face of evil, and a heartrending reckoning of the terrible choices we make for the ones we love.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Pinus radiata (radiata pine) is a versatile, fast-growing, medium-density softwood, suitable for a wide range of end-uses. Its silviculture is highly developed, and is built on a rm foundation of over a century of research, observation and practice. Radiata pine is often considered a model for growers of other plantation species. This book explores current knowledge of, and experience with radiata pine forest plantation management and examines its long-term sustainability. Radiata pine management needs to integrate the biological aspects of tree-growing, with socio-economics, management objectives, practical considerations and other constraints and opportunities. Although stands of radiata pine may appear to be simple, they are actually quite complex ecosystems because they contain large, long-lived trees that change dramatically over time and interact in changing ways with the environment and with other organisms. The focus of this book is on the principles and practices of growing radiata pine sustainably. It also looks ahead to emerging challenges facing radiata pine plantation management, such as the effects of climate change, new diseases and other threats, and meeting changing product needs and societal demands."--Page 4 of cover.

Download or read book Wood Modification written by Callum A. S. Hill and published by John Wiley & Sons. This book was released on 2007-02-06 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is exclusively concerned with wood modification, although many of these processes are generic and can be applied to other lignocellulosic materials. There have been many rapid developments in wood modification over the past decade and, in particular, there has been considerable progress made in the commercialisation of technologies. Topics covered include: The use of timber in the 21st century Modifying the properties of wood Chemical modification of wood: Acetic Anhydride Modification and reaction with other chemicals Thermal modification of wood Surface modification Impregnation modification Commercialisation of wood modification Environmental consideration and future developments This is the first time that a book has covered all wood modification technologies in one text. Although the book covers the main research developments in wood modification, it also puts wood modification into context and additionally deals with aspects of commercialisation and environmental impact. This book is very timely, because wood modification is undergoing huge developments at the present time, driven in part by environmental concerns regarding the use of wood treated with certain preservatives. There has been considerable commercial interest shown in wood modification over the past decade, with products based upon thermal modification, and furfurylation now being actively being marketed. The next few years will see the commercialisation of acetylation and impregnation modification. This is a new industry, but one that has enormous potential. This book will prove useful to all those with an interest in wood modification including researchers, technologists and professionals working in wood science and timber engineering, wood preservation, and well as professionals in the paper and pulp industries, and those with an interest in the development of renewable materials.

This book was released on 1997 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Montreal Process was formed to advance the development of internationally agreed-upon criteria & indicators for sustainable forest management. The Canadian commitment to this process is demonstrated by the development of a domestic set of seven criteria & indicators, six of this relate to forest conditions, attributes, functions, or benefits. The seventh relates to the overall policy framework that can facilitate sustainable forest management and support efforts to conserve, maintain, or enhance the conditions, attributes, and benefits captured in the first six criteria. This report begins with an introduction describing forest ecosystems and forest management in Canada, explaining the area of forest covered by the report, and indentifying Canada-specific forest management characteristics to help place the criteria & indicators framework in context. The main section contains reports on the criteria, each with an introduction and reports on the corresponding indicators (what is being measured, indicator data or factual description, information sources). The final section contains a summary of all the criteria as well as an overview of Canada's ability to report on them and plans to enhance reporting capability in the future. Includes glossary.

Available in PDF, EPUB and Kindle. Book excerpt: Essential reading for anyone interested in the most famous American crime of the twentieth century Since its original publication in 2004, The Case That Never Dies has become the standard account of the Lindbergh Kidnapping. Now, in a new afterword, historian Lloyd C. Gardner presents a surprise conclusion based on recently uncovered pieces of evidence that were missing from the initial investigation as well as an evaluation of Charles Lindbergh’s role in the search for the kidnappers. Out of the controversies surrounding the actions of Colonel Lindbergh, Norman Schwarzkopf, commander of the New Jersey State Police, and FBI director J. Edgar Hoover, Gardner presents a well-reasoned argument for what happened on the night of March 1, 1932. The Case That NeverDies places the Lindbergh kidnapping, investigation, and trial in the context of the Depression, when many feared the country was on the edge of anarchy. Gardner delves deeply into the aspects of the case that remain confusing to this day, including Lindbergh’s dealings with crime baron Owney Madden, Al Capone’s New York counterpart, as well as the inexplicable exploits of John Condon, a retired schoolteacher who became the prosecution’s best witness. The initial investigation was hampered by Colonel Lindbergh, who insisted that the police not attempt to find the perpetrator because he feared the investigation would endanger his son’s life. He relented only when the child was found dead. After two years of fruitless searching, Bruno Richard Hauptmann, a German immigrant, was discovered to have some of the ransom money in his possession. Hauptmann was arrested, tried, and sentenced to death. Throughout the book, Gardner pays special attention to the evidence of the case and how it was used and misused in the trial. Whether Hauptmann was guilty or not, Gardner concludes that there was insufficient evidence to convict him of first-degree murder. Set in historical context, the book offers not only a compelling read, but a powerful vantage point from which to observe the United States in the 1930s as well as contemporary arguments over capital punishment.
