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.

Download or read book Wood Properties and Processing written by Miha Humar and published by MDPI. This book was released on 2020-05-23 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood-based materials are CO2-neutral, renewable, and considered to be environmentally friendly. The huge variety of wood species and wood-based composites allows a wide scope of creative and esthetic alternatives to materials with higher environmental impacts during production, use and disposal. Quality of wood is influenced by the genetic and environmental factors. One of the emerging uses of wood are building and construction applications. Modern building and construction practices would not be possible without use of wood or wood-based composites. The use of composites enables using wood of lower quality for the production of materials with engineered properties for specific target applications. Even more, the utilization of such reinforcing particles as carbon nanotubes and nanocellulose enables development of a new generation of composites with even better properties. The positive aspect of decomposability of waste wood can turn into the opposite when wood or wood-based materials are exposed to weathering, moisture oscillations, different discolorations, and degrading organisms. Protective measures are therefore unavoidable for many outdoor applications. Resistance of wood against different aging factors is always a combined effect of toxic or inhibiting ingredients on the one hand, and of structural, anatomical, or chemical ways of excluding moisture on the other.
Download or read book Nondestructive Characterization of Materials IV written by J.F. Bussière and published by Springer Science & Business Media. This book was released on 1992-02-29 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a great deal of interest in extending nondestructive technologies beyond the location and identification of cracks and voids. Specifically there is growing interest in the application of nondestructive evaluation (NOEl to the measurement of physical and mechanical properties of materials. The measurement of materials properties is often referred to as materials characterization; thus nondestructive techniques applied to characterization become nondestructive characterization (NDCl. There are a number of meetings, proceedings and journals focused upon nondestructive technologies and the detection and identification of cracks and voids. However, the series of symposia, of which these proceedings represent the fourth, are the only meetings uniquely focused upon nondestructive characterization. Moreover, these symposia are especially concerned with stimulating communication between the materials, mechanical and manufacturing engineer and the NDE technology oriented engineer and scientist. These symposia recognize that it is the welding of these areas of expertise that is necessary for practical development and application of NDC technology to measurements of components for in service life time and sensor technology for intelligent processing of materials. These proceedings are from the fourth international symposia and are edited by c.o. Ruud, J. F. Bussiere and R.E. Green, Jr. . The dates, places, etc of the symposia held to date area as follows: Symposia on Nondestructive Methods for TITLE: Material Property Determination DATES: April 6-8, 1983 PLACE: Hershey, PA, USA CHAIRPERSONS: C.O.

Download or read book Wood Modification Technologies written by Dick Sandberg and published by CRC Press. This book was released on 2021-07-15 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: The market for durable products using modified wood has increased substantially during the last few years. This is partly because of the restriction on the use of toxic preservatives due to environmental concerns, and to lower maintenance cost and time. Furthermore, as sustainability becomes a greater concern, the environmental impact of construction and interior materials is factored in planning by considering the whole life cycle and embodied energy of the materials used. Wood is modified to improve its intrinsic properties, enhance the range of applications of timber, and to acquire the form and functionality desired by engineers without calling the environmental friendliness into question. Wood modification processes are at various stages of development, and the challenges faced in scaling up to industrial applications differ. The aim of this book is to put together the key elements of the changes of wood constituents and the related changes in wood properties of modified wood. Further, a selection of the principal technologies implemented in wood modification are presented. This work is intended for researchers, professionals of timber construction, as well as students studying the science of materials, civil engineering and architecture. This work is not exhaustive, but intends to deliver an outline of the scientific disciplines necessary to apprehend the technologies of wood modification and its behavior during treatment, as well as during its use.

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.

Book excerpt: This volume highlights recent research efforts in the conservation and investigation of works of art on wood. Through eleven case studies it showcases different experimental methods ranging from X-ray analysis of objects to the study of cross-sections made from micro-samples. New research focusing on the technical study, treatment and assessment of works of art on wood in its many forms is featured in this edited volume. Technical studies include the attribution and investigations of a triptych by Hans Memling and a sculpture from workshop of Michel and Gregor Erhart, decorated Syrian rooms, and investigations of finely carved Gothic wooden objects. Synchrotron-based methods are presented for studying the alteration of 19th c. verdigris in Norway, and multi-analytical methods are employed for the investigations of 16th to 19th c. East Asian lacquer from the Kunsthistorisches Museum in Vienna. Novel methods for the cleaning of gilded surfaces using gels and emulsions are shown, as are innovative strategies for the consolidation for waterlogged wood, providing key data for the assessment of risks and benefits of new methods, and the short and long-term effects on gilding layers and archaeological wood. The book clearly shows how collaboration between engineers, physicists, biologists and chemists and conservators of different types of materials can lead to new research in conservation science. This book is crucial reading for conservators and conservation scientists, as well as for technical art historians, providing key methodological case studies of polychromy from different temporal and geographical contexts.

Download or read book Saproxylic Insects written by Michael D. Ulyshen and published by Springer. This book was released on 2018-05-21 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers extensive information on insect life in dying and dead wood. Written and reviewed by leading experts from around the world, the twenty-five chapters included here provide the most global coverage possible and specifically address less-studied taxa and topics. An overarching goal of this work is to unite literature that has become fragmented along taxonomic and geographic lines. A particular effort was made to recognize the dominant roles that social insects (e.g., termites, ants and passalid beetles) play in saproxylic assemblages in many parts of the world without overlooking the non-social members of these communities. The book is divided into four parts: · Part I “Diversity” includes chapters addressing the major orders of saproxylic insects (Coleoptera, Diptera, Hymenoptera, Hemiptera, Lepidoptera and Blattodea), broadly organized in decreasing order of estimated global saproxylic diversity. In addition to order-level treatments, some chapters in this part discuss groups of particular interest, including pollinators, hymenopteran parasitoids, ants, stag and passalid beetles, and wood-feeding termites. · Part II “Ecology” discusses insect-fungal and insect-insect interactions, nutritional ecology, dispersal, seasonality, and vertical stratification. · Part III “Conservation” focuses on the importance of primary forests for saproxylic insects, offers recommendations for conserving these organisms in managed forests, discusses the relationships between saproxylic insects and fire, and addresses the value of tree hollows and highly-decomposed wood for saproxylic insects. Utilization of non-native wood by saproxylic insects and the suitability of urban environments for these organisms are also covered. · Lastly, Part IV “Methodological Advancements” highlights molecular tools for assessing saproxylic diversity. The book offers an accessible and insightful resource for natural historians of all kinds and will especially appeal to entomologists, ecologists, conservationists and foresters.
