It was not until the turn of the previous century that the human dependence on wood was higher than any other sources of energy. It was considered to be a one of the wonders of nature that was created to provide comfort and support to the humanly civilized way of living. Although there is no historical confirmation about the first use of wood by humans, still it dates back to a very long period of time when it was a major lifestyle resource for our ancestors from the ancient times. Wood was utilized not just as a source of heating or drawing energy, but also as a material for making tools, household furniture, sheltering objects, transporting objects, decorative purposes, culinary items and cutlery, and a large number of other items that one can only imagine. As per historians, wood was the original material used in most of the first time scientific inventions. To date, wood is a very important part of human living. Life without wood can be very difficult and expensive.

Download or read book Tilting written by Robert Mellin and published by Princeton Architectural Press. This book was released on 2008-09-17 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an almost elemental appeal in the rural fishing villages of Nova Scotia, Maine, and Newfoundland. Their intimate connection to nature, to the land, water, and (often harsh) weather; their reliance on ingenuity, on-hand materials, and craftsmanship; and their values of thrift and endurance serve as inspiration and as touchstones for those of us caught up in the hubbub of modern life. Tilting, Newfoundland is a celebration of all these virtues and an eclectic documentation of the buildings, landscape, and lifestyle of this remote community on a small island far off the Canadian coast. Through photographs, firsthand historical anecdotes, and delicate pencil drawings, author Robert Mellin presents a personal account of Tilting's houses, outbuildings, furniture, tools, fences, and docks, and, in the process, the way of life of Tilting. Mellin describes how houses are built for mobility and then "launched," or moved; how houses are detailed and constructed; how cabbage houses are built out of overturned boats; and the difference between picket, paling, and riddle fences-with diagrams in case you want to build your own. Part journal, part sketchbook, part oral history, Tilting, Newfoundland is a treasure chest of a book that offers new discoveries with each reading, and a reminder of the simpler aspects of life and building.
Download or read book Design and Construction of Solar Kiln for Lumber Drying written by Awam Joel and published by GRIN Verlag. This book was released on 2019-06-18 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2015 in the subject Engineering - Chemical Engineering, , language: English, abstract: This research aims to design and fabricate a solar kiln dryer that uses a solar panel to trap the sun’s rich energy and also the design of an inverter that converts the direct current of the sun to an alternative current that will charge the battery and power heater element for drying. The principal mode of heat transfer is convection. The temperature of the incoming stream of air is raised by the heating element, a circular motion fan drives the heated air uniformly through the heating chamber, in this way heat is convectively transferred from the hot air to the cold air. Wood is a hygroscopic material which gains moisture content as a result of changes in humidity. Hygroscopicity is one of the most distinctive properties of wood. Any kind of wood product absorbs and desorbs moisture from the surrounding air until it reaches equilibrium moisture content (EMC), a balance point between the wood’s moisture content and that of the surrounding environment. Fresh cut lumber contains a great deal of water. If the water is not removed, the lumber can’t be used to produce a high quality finished product. Properly dried lumber sells for a higher price and is much easier to work with than lumber that have not been dried. When lumber is well dried it machines better, glues better, and finishes better. Drying also improves the strength of the lumber, kills infestations, hardens pitch, preserves colour, reduces weight and controls shrinkage. Lumber that is not dried under controlled conditions is prone to warping, staining, and other degradations that diminishes its selling price and workability.
Download or read book Improvements in Solar Dry Kiln Design written by Eugene M. Wengert and published by . This book was released on 1971 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in solar drying of lumber has increased in recent years because previous results had indicated that: Drying times are shorter and final moisture contents are lower in solar drying than in air drying; much less lumber degrade occurs in solar drying when compared to air drying; and the cost of energy is less in solar drying than in kiln drying. Work in the field of solar drying has reached the point at which dryer designs are being modified or need to be modified to provide more efficient dryers. In order that these modifications can be made intelligently, it is necessary to identify the weak areas (such as excessive solar reflectance from the walls) in the present dryer designs. The objective of this study was to identify the major energy losses in the solar dryer at Colorado State University, and then to suggest various design changes, based on theoretical considerations, to reduce these losses to leave more energy for the primary task of drying wood.
Download or read book FPL Design for Lumber Dry Kiln Using Solar wood Energy in Tropical Latitudes written by John L. Tschernitz and published by . This book was released on 1985 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing countries with a timber resource that can be manufactured into finished products either for local use or export often lack the capital to build high-cost dry kilns. Many of these countries are in the tropics where solar radiation and ambient temperatures are high. The low-cost solar/wood energy lumber dry kiln described in this report was designed and tested by the Forest Products Laboratory (FPL) for such countries where solar dry kilns can be built and operated at low cost. The FPL design is for a 6,000-fbm capacity kiln having an insulated drying compartment, an external horizontal solar collector, and a furnace room containing a wood burner. Capacities larger or smaller than 6,000 fbm are also possible. This design allows collector and wood burner sizing to match the energy demands of the dryer. The design also incorporates low-cost controls that allow unattended drying when operated as a solar-only dryer. Manual firing is necessary when the wood-burning system is supplying the energy. This kiln design is the final, commercial-size version established after years of testing several 1,000-fbm capacity prototypes. In December 1984 a kiln of this design was built in Sri Lanka at a factory that manufactures furniture and laminated beams from rubber and coconut wood.

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 The Making of the Atomic Bomb written by Richard Rhodes and published by Simon and Schuster. This book was released on 2012-09-18 with total page 890 pages. Available in PDF, EPUB and Kindle. Book excerpt: **Winner of the Pulitzer Prize, the National Book Award, and the National Book Critics Circle Award** The definitive history of nuclear weapons—from the turn-of-the-century discovery of nuclear energy to J. Robert Oppenheimer and the Manhattan Project—this epic work details the science, the people, and the sociopolitical realities that led to the development of the atomic bomb. This sweeping account begins in the 19th century, with the discovery of nuclear fission, and continues to World War Two and the Americans’ race to beat Hitler’s Nazis. That competition launched the Manhattan Project and the nearly overnight construction of a vast military-industrial complex that culminated in the fateful dropping of the first bombs on Hiroshima and Nagasaki. Reading like a character-driven suspense novel, the book introduces the players in this saga of physics, politics, and human psychology—from FDR and Einstein to the visionary scientists who pioneered quantum theory and the application of thermonuclear fission, including Planck, Szilard, Bohr, Oppenheimer, Fermi, Teller, Meitner, von Neumann, and Lawrence. From nuclear power’s earliest foreshadowing in the work of H.G. Wells to the bright glare of Trinity at Alamogordo and the arms race of the Cold War, this dread invention forever changed the course of human history, and The Making of The Atomic Bomb provides a panoramic backdrop for that story. Richard Rhodes’s ability to craft compelling biographical portraits is matched only by his rigorous scholarship. Told in rich human, political, and scientific detail that any reader can follow, The Making of the Atomic Bomb is a thought-provoking and masterful work.
