Download or read book Physical and Related Properties of 145 Timbers written by J.F. Rijsdijk and published by Springer Science & Business Media. This book was released on 1994-10-31 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: To obtain the best attainable end-use stability of a wooden product it is essential to have information on the movement and shrinkage that may be expected. In this context, it is essential when drying timber to choose an accurate drying schedule in relation to the shrinkage figures and the risk of deformation. Generally, many timber properties are closely related to the density and the nominal specific gravity. With the given detailed information (per wood species), the water content (amount of evaporation and energy in timber drying) or the void volume (in case of impregnation, in order to estimate the maximum uptake of a liquid) in the wood can be calculated. The physical properties of 145 commercial timbers have been determined in the past decades. They comprise the shrinkage and swelling values, equilibrium moisture content, hysteresis, density and nominal specific gravity, including the variation coefficients of these values. The shrinkage, swelling and hysteresis are presented in graphic form; the other information in tabular form. Additional information about some other properties of physical nature has been added, e.g. gluelam products and rattan.

Download or read book Timber written by H E Desch and published by CRC Press. This book was released on 1996-06-13 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nearly 60 years, Timber: Structure, Properties, Conversion, and Use has been the authoritative text on timber technology. Now in its seventh edition, this book remains a vital resource, providing accurate, comprehensive, and fact-driven information for students and professionals in the field. From basic coverage of timber structure, properties, processing, and utilization, to more in-depth scientific investigations, this book covers all the issues and topics of concern to readers with a wide range of levels of sophistication. Timber technology has not stood still since the last revision; Timber: Structure, Properties, Conversion, and Use has kept the pace, exploring such high-tech topics as computer-aided wood identification and log conversion, radio frequency drying of wood, enhancement of wood with plastics, application of preservatives with high-pressure vacuum systems, and the development and application of flame-retardant solutions. Other timely updates include enlarging the chapter on mechanical performance to cover elastic behavior, toughness, and the use of structural-sized timber for strength tests. The chapter on board materials has also been extensively updated and enlarged to include information on new boards and structural composites that have emerged since the last edition. One of the most important strengths of Timber: Structure, Properties, Conversion, and Use is its versatility as a reference for timber professionals while remaining approachable to students in the field. Evidence of the book?s comprehensiveness and versatility becomes clear as it teaches readers about such wide-ranging topics as: identification and nomenclature of timbers variability in cellular features between species principal chemical constituents in timber structural variability caused by natural defects such as bark pockets, resin streaks, and brittleheart determination of density and moisture content in timber thermal and acoustic properties of wood conversion equipment such as circular saws, band saws, frame saws, and chipper canters health and safety issues in the industry adhesives, metal connectors, and joint design forest and millyard pests application of preservatives and finishes From basic identification and timber nomenclature to methods of sap displacement and tests of electrical conductivity, Timber: Structure, Properties, Conversion, and Use covers it all. And while it is no longer possible for any one individual to write authoritatively on every aspect of timber technology, embracing as it does structure, properties, conversion, utilization, and behavior in service, J. M. Dinwoodie has gathered expert opinions and expanded on original author H. E. Desch?s approach and vision to continue to provide the authoritative text on timber technology.

Download or read book Forest Plans of North America written by Jacek P. Siry and published by Academic Press. This book was released on 2015-03-13 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Plans of North America presents case studies of contemporary forest management plans developed for forests owned by federal, state, county, and municipal governments, communities, families, individuals, industry, investment organizations, conservation organizations, and others in the United States, Canada, and Mexico. The book provides excellent real-life examples of contemporary forest planning processes, the various methods used, and the diversity of objectives and constraints faced by forest owners. Chapters are written by those who have developed the plans, with each contribution following a unified format and allowing a common, clear presentation of the material, along with consistent treatment of various aspects of the plans. This work complements other books published by members of the same editorial team (Forest Management and Planning, Introduction to Forestry and Natural Resource Management), which describe the planning process and the various methods one might use to develop a plan, but in general do not, as this work does, illustrate what has specifically been developed by landowners and land managers. This is an in-depth compilation of case studies on the development of forest management plans by the different landowner groups in North America. The book offers students, practitioners, policy makers, and the general public an opportunity to greatly improve their appreciation of forest management and, more importantly, foster an understanding of why our forests today are what they are and what forces and tools may shape their tomorrow. Forest Plans of North America provides a solid supplement to those texts that are used as learning tools for forest management courses. In addition, the work functions as a reference for the types of processes used and issues addressed in the early 21st century for managing land resources. - Presents 40-50 case studies of forest plans developed for a wide variety of organizations, groups, and landowners in North America - Illustrates plans that have specifically been developed by landowners and land managers - Features engaging, clearly written content that is accessible rather than highly technical, while demonstrating the issues and methods involved in the development of the plans - Each chapter contains color photographs, maps, and figures

Available in PDF, EPUB and Kindle. Book excerpt: Forest soil characteristics are not only unique but their interpretation also differs from cropland soils. Just as there are diverse forest types, there are many soil variants that need different management. Today, forest plantations are being intensively managed for profitable timber, pulpwood and energy production. Site selection, species selection, site productivity evaluation, silvicultural treatments, and soil amendments need crucial soil information. This book provides a comprehensive overview of the physical, chemical and biological properties of forest soils and their implications on forest vegetation. Topics discussed include: major forest types of the world and their associated soils; forest biomass and nutrient dynamics; organic matter turnover and nutrient recycling; forest soil disturbance; forest soil and climate change; and forest soil management and silvicultural treatments.

Download or read book Control of Decay in Pulp and Pulp Wood written by Otto Kress and published by . This book was released on 1925 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: On account of rather serious losses in stored wood and wood pulp, the authors made a study of the causes of decay in wood and wood pulp and conditions which favor it, complete with mill tests, and laboratory investigations. To combat deterioration during storage, careful attention must be given to the elimination of sources of infection, and the chemicals best adapted for this are identified, and an application scheme outlined. The authors investigate fungi that inhabit pulp, which do more damage than molds, and cause certain chemical actions on ground-wood pulp. It is undoubtedly the most extensive discussion that has yet been published on this subject; the authors and the Forest Products Laboratory deserve sincere thanks.

Download or read book Wood Extractives and Their Significance to the Pulp and Paper Industries written by W. E. Hillis and published by Academic Press. This book was released on 2014-05-12 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood Extractives and their Significance to the Pulp and Paper Industries focuses on the promotion of the study of the biochemistry of wood extractives and to elaborate on the effects these materials may pose to the manufacture of pulp and paper. The publication first elaborates on wood, distribution and formation of polyphenols within the tree, and the simple polyphenolic constituents of plants. Discussions focus on the factors affecting the amounts of polyphenols present in living tissues, glycosidic combination, flavonols, anthocyanins, and leucoanthocyanins, formation of carbohydrates in the tree, types of polyphenols in different tissues of uninjured trees, and variation in structure and properties of wood. The text then examines lignans and condensed and hydrolyzable tannins. The manuscript takes a look at the alicyclic acid precursors of polyphenols, biosynthesis of polyphenols, and tropolones. Topics include tropolones occurring in wood, polymeric polyphenols, synthesis of pre-aromatic compounds, shikimic acid, and quinic acid. The book then ponders on the influence of extractives on the pulping of wood and the influence of extractives on the color of ground wood and newsprint. The publication is a valuable reference for researchers interested in the processes and methodologies involved in the manufacture of pulp and paper.
