This book was released on 2013-04-17 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood-destroying fungi play an important role in nature, because they are the only forms of life capable of reducing wood to its initial constituents. However, they can also be dangerous for people and property, as they can impair the stability and fracture-safety of trees. This book gives detailed information, based on new and original scientfic findings, on the examination and effects of the most important species of fungi associated with failure of infected urban trees. In addition, new ways are presented for predicting the advance of decay in the living tree. The subject is illustrated and made easily accessible by numerous colored photos of fungus fruit bodies, defect symptoms, and macroscopic and microscopic pictures of wood decay. A detailed introduction to the fundamentals of wood pathology provides a way into the subjects of applied mycology and tree care for readers without previous special knowledge. Francis W.M.R.

Download or read book Acoustic Tomography for Decay Detection in Red Oak Trees written by and published by . This book was released on 2007 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of tree stability analysis uses both biological and engineering principles in attempting to rate a tree's structural soundness and make reasonable predictions of potential for failure. In such analysis, arborists are often challenged by internal structural defects hidden from view within the trunks. This paper reports the results of an investigation using acoustic tomography to detect internal decay in park trees. Two century-old red oak (Quercus rubra) trees located at the Capitol Park in Madison, Wisconsin, were nondestructively evaluated using an acoustic tomography technique. The trees were subsequently felled, and a disk at each test location was obtained and examined. We found that the light-colored zones in the tomograms were larger than the true decay present in the disks. The oversized light-colored areas were the composite effects of both decay and large internal cracks. The results of this study demonstrated that acoustic tomography cannot distinguish between large internal cracks and heartwood decay. To make a better assessment of internal condition for urban trees, resistance microdrilling should also be used prior to tree removal.

Download or read book Nondestructive Evaluation of Wood written by Forest Service (U S ) and published by Government Printing Office. This book was released on 2015 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nature's engineering of wood through genetics, wind, and weather creates a wide variability in wood as a material. Consequently, manufacture and users of wood products are frequently frustrated in dealing with the forest resource. Manufacturers sometimes argue that wood is difficult to consistently process into quality products because of the wide range of properties that exist in this raw material. Users of wood products can be equally frustrated with the performance variability found in finished products. Nondestructive evaluation (NDE) technologies have contributed significantly toward eliminating the cause of these frustrations. NDE technologies have been developed and are currently used in lumber and veneer grading programs that result in engineered materials that have consistent well-defined performance characteristics. This brief volume explores some of the processes that are used to manufacture wood, including green wood technology and provides a bit of history to wood production and its uses too.

This book was released on 2005 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a project to assess the accuracy of two instruments for detecting wood decay in trees in order to assess their accuracy & applicability for collecting decay data in Ontario forests. The instruments tested were the Silbert Digital MicroProbe and the Resistograph F400. In general, both instruments measure & record the resistance encountered by a thin probe as it drills through wood. The use of these instruments was compared with visually measuring decay in 60 aspen logs and 71 sugar maple logs. The instruments were also used in boreal mixedwood & tolerant hardwood stands to determine their operability under field conditions.
Download or read book Science of Wood Degradation and its Protection written by R. Sundararaj and published by Springer Nature. This book was released on 2022-03-16 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book covers all aspects of wood degradation from its formation and growing in trees to its end usages when it is put into human usage. Wood is an age-old traditional fascinating material with a sensory-rich immersive experience that kindles aesthetics and creativity. The utility, durability, and functionality of wood render it a cosmopolitan material. It constitutes an integral part of human lives from ancient times to modern societies being used by various sectors viz., construction, furniture, panel products, paper and pulp, sports goods, agricultural implements, etc., Wood, being a biological material, is susceptible to degradation both by physical and biological means, and the need to protect the wood and prevent heavy economic losses constitutes a major challenge. Also, wood formed by the trees is the major sinks of carbon and the carbon remains locked-up for the life of the wood, thereby serving as important tool to mitigate the climate change. But the carbon stored in wood returns to the atmosphere when it degrades and will have positive effect on climate change. Hence, wood protection aiming for extending the service life of wood plays a key role in locking the carbon for a longer period in the wood and also substantially reduce the demand and depletion of forest resources. The book focuses on wood as an important natural bio-resource, inventory of wood protection, usage, utilization, preservatives, protection technologies and wood protection from all forms of degradation. Special focus is given on the eco-friendly way of protecting wood and its importance in mitigating climate change. The book is useful for Indian and international readers, who are working in wood domains. It is of interest to wood technologists, teachers, researchers, climate change scientists, capacity builders, and policymakers. It is of immense importance as a guide and study material to the graduate and postgraduate students of wood science in various universities of India and abroad.

Download or read book Agarwood written by Rozi Mohamed and published by Springer. This book was released on 2016-06-01 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives readers new information to understand the mechanism of agarwood induction and therefore eradicate the myths surrounding agarwood formation. One of the challenges in conserving agarwood resources is species identification. In this book, taxonomy and systematics of agarwood-producing trees from historical and recent perspectives is discussed, and tips are given for identifying cultivated species. In addition, color illustrations are given to highlight vegetative and reproductive characteristics as well as anatomical features, for identification purposes of both plant and agarwood sources. Another challenge that planters are facing is in acquiring the correct method for agarwood induction, thus development of agarwood induction technologies will be reviewed. A chapter dedicated to bioinduction is included. The book will comprise a chapter on the use of non-destructive technology as a management tool for cultivating agarwood. The book also discusses issues relating to agarwood grades. The absence of an international standard that is acceptable by producer and consumer countries further complicates the issue. Other useful information includes a systematic revelation of agarwood constituents and their complex chemistry, and highlights on a specific pharmaceutical property.
