Download or read book Wood Water Relations written by Christen Skaar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is formed in an essentially water-saturated environment in the living tree, and the cell wall remains in this state until the water flow from the roots is interrupted, such as by felling the tree. The wood then begins to lose most of its moisture by drying, resulting in changes in most of its physical properties. These changes, and their relationship to the environment to which the wood is subsequently ex posed, are the subject of this book. The text consists of six chapters. The first chapter discusses cer tain empirical relationships between wood and water, methods of measuring wood moisture content, factors which affect its equilib rium moisture content, and the effect of moisture content on wood strength. The second chapter treats the thermodynamics of moisture sorption by wood, inc1uding enthalpy, entropy, and free energy changes. The third chapter discusses some of the theories which have been proposed to explain the sorption isotherms for hygroscopic ma terials such as wood. Chapter 4 considers hygroexpansion or the shrinking and swelling of wood associated with moisture change. Chapter 5 is concerned with how moisture moves through the cell wall of wood in response to both moisture and temperature gradients. The sixth and final chapter discusses the theoretical and practical aspects of the electrical resistance and dielectric properties of wood, in c1uding the principles involved in their application in electrical moisture meters.

Available in PDF, EPUB and Kindle. Book excerpt: Builders, inspectors and engineers undertaking moisture measurements on site in many instances do not possess the necessary background for using or interpreting moisture meter readings from wood and wood-based products. Because judgement is also needed in their interpretation, this document has been prepared to provide both detailed instructions and background information to assist persons involved in these endeavours. The objective of this report is to assist those not fully informed in wood moisture measurement technology and to provide general guidance with respect to measuring wood moisture content in field conditions. The document outlines the types of available moisture meters, a process of how to take moisture readings, where to take moisture readings and how the moisture readings are corrected for temperature and wood species. In addition, the document will provide a general discussion about steps builders and designers can take to minimize construction complications due to moisture.
Download or read book Norwegian Wood written by Lars Mytting and published by Abrams. This book was released on 2015-10-06 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A surprise best-seller which, apparently, has the power to turn even the most feeble of us into axe-wielding lumberjacks.” —Independent The latest Scandinavian publishing phenomenon is not a Stieg Larsson-like thriller; it’s a book about chopping, stacking, and burning wood that has sold more than 200,000 copies in Norway and Sweden and has been a fixture on the bestseller lists there for more than a year. Norwegian Wood provides useful advice on the rustic hows and whys of taking care of your heating needs, but it’s also a thoughtful attempt to understand man’s age-old predilection for stacking wood and passion for open fires. An intriguing window into the exoticism of Scandinavian culture, the book also features enough inherently interesting facts and anecdotes and inspired prose to make it universally appealing. The U.S. edition is a fully updated version of the Norwegian original, and includes an appendix of U.S.-based resources and contacts. “A how-to guide as well as a celebration of wood—its scent, its variability, and the way it can connect modern life to simpler times . . . You don’t need to have a wood-burning stove or fireplace to be captivated by the craft and lore surrounding a Stone Age method of creating heat.” —The Boston Globe “The book has spread like wildfire.” —Daily Mail “A how-to book with poetry at its heart.” —The Times Literary Supplement
Download or read book A Microwave Method for Measuring Moisture Content Density and Grain Angle of Wood written by William Lanpheer James and published by . This book was released on 1985 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The attenuation, phase shift and depolarization of a polarized 4.81-gigahertz wave as it is transmitted through a wood specimen can provide estimates of the moisture content (MC), density, and grain angle of the specimen. Calibrations are empirical, and computations are complicated, with considerable interaction between parameters. Measured dielectric parameters, however, correlate uniquely and repeatably with MC over a range of MC at least as great as 100 percent of the dry weight of the wood. Grain angle can be deduced reliably when the specimen thickness and MC are great enough to introduce sufficient dielectric anisotropy to appreciably depolarize the incident wave. At present, the apparatus and techniques are very complex, but the principles developed by this research show the method to be feasible for nondestructive testing of lumber as it is produced.
Download or read book Methods of Measuring Moisture in Building Materials and Structures written by Lars-Olof Nilsson and published by Springer. This book was released on 2018-04-13 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: RILEM TC 248-MMB was established in 2012 with the main aim to improve and distribute knowledge related to moisture measurement in construction materials in various scientific and industrial applications. Properties and performance of building materials and structures are influenced to a large extent by the moisture conditions in the materials. Obvious examples are heat conductivity, shrinkage and creep, transport properties, most types of deterioration, discoloration etc. For research and applications the moisture conditions must be quantified, by measurements in the laboratory or under field conditions. There is much variation in methods being used, even within the same topic, in different countries, both with regard to materials and to applications. No consensus whatsoever does exist. For the construction industry it is important to be able to quantify the moisture conditions in an accurate way in various applications. This state-of-the-art report is divided into two parts, Principles and Applications, with altogether 28 chapters on various moisture measuring principles and a number of applications.

Download or read book Moisture Content Measurements in Wood and Wood Based Materials Advancements in Sensor Calibration and Low Moisture Content Regime written by Nitin Shukla and published by . This book was released on 2014 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is a major structural material used in the construction of residential and commercial buildings. In situ and continuous measurement of moisture in a wood element of the building envelope is critical in preventing the occurrence of moisture related damages to the building structure, and also helps in determining the thermal and energy performance of the system. Moisture content of a wood assembly may serve as an indicator of the effectiveness and potential condensation-related damage to the adjoining thermal insulation layers in the building envelope. Typically, the moisture content in a wood component is determined by measuring the electrical resistance across a pair of metallic pin sensors, with correlation or calibration between resistance and moisture content already established for the studied wood species. As the wood dries from fiber saturation point (FSP) to equilibrium moisture content (EMC), the resistance typically increases by 4 orders of magnitude from hundreds of k? to G?. Typical resistance measurement instrumentation schemes such as voltage divider and multimeters are often incapable to cover this wide dynamic range of resistance. To further complicate the measurements, low EMC values of 5 %-10 % range correspond to very high resistances in the range of M?-G?, a regime that has remained challenging to measure because of lower current and leakage issues. To circumvent these issues, we developed an instrumentation methodology based on a simple voltage divider circuit in combination with a data-logger with reference resistors selected in such a manner to maximize the dynamic range of the measurement with sufficient accuracy and resolution for higher resistance range. The results showed significant improvements in the dynamic range and resolution for the MC measurements.
Download or read book Water Relationships in Foods written by Harry Levine and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 825 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was developed from the papers presented at a symposium on "Water Relationships in Foods," which was held from April 10-14, 1989 at the 197th National Meeting of the American Chemical Society in Dallas, Texas, under the auspices of the Agricultural and Food Chemistry Division of ACS. The editors of this book organized the symposium to bring tagether an es teemed group of internationally respected experts, currently active in the field of water relationships in foods, to discuss recent advances in the 1980's and future trends for the 1990's. It was the hope of all these con tributors that this ACS symposium would become a memorable keystone above the foundation underlying the field of "water in foods. " This strong foundation has been constructed in large part from earlier technical conferences and books such as the four milestone International Symposia on the Properties of Water (ISOPOW I-IV), the recent IFT BasicSymposium on "Water Activity" and Penang meeting on Food Preservation by Maisture Control, as well as the key fundamental contributions from the classic 1980 ACS Symposium Series #127 on Water in Polymers, and from Felix Franks' famous seven-volume Comprehensive Treatise on Water plus five subsequent volumes of the ongoing Water Science Reviews. The objective of the 1989 ACS symposiumwas to build on this foun dation by emphasizing the most recent and maj or advanc.
