Transport Processes in Wood


Book Description

This book has a similar subject content to the author's previous Flow in Wood but with substantial updating due to the abundance of research in the wood science field since 1971. Several different concepts have been introduced, particularly in regard to wood-moisture relation ships. The role of water potential in the equilibria between wood and its humid and moist environments is considered. Two theories are introduced to explain the nonisothermal transport of bound water in the steady and unsteady states. As in the former text, the wood-. structure relationship is emphasized . . The author is especially grateful to Dr. C. Skaar for his careful and critical review of much of the manuscript and for the productive dis cussions of many of the concepts. Dr. T. E. Timell, the series editor, rendered major assistance in the preparation of Chap. 2 and in his editing of the manuscript. The author wishes to thank Dr. W. A. Cote, Mr. A. C. Day, and Mr. J. J. McKeon for providing electron micro graphs, Mr. G. A. Snyder for his photography of much of the art work, Dr. C. H. de Zeeuw for his advice in the field of wood anatomy, and Ms. Mary M. Siau for her careful rendition of the art work. Apprecia tion is extended to Miss Judy A. Barton and Mrs. Stephanie V. Micale for their work in typing and checking the manuscript. Mr. J.

Timber and Forestry in Qing China


Book Description

In the Qing period (1644–1912), China's population tripled, and the flurry of new development generated unprecedented demand for timber. Standard environmental histories have often depicted this as an era of reckless deforestation, akin to the resource misuse that devastated European forests at the same time. This comprehensive new study shows that the reality was more complex: as old-growth forests were cut down, new economic arrangements emerged to develop renewable timber resources. Historian Meng Zhang traces the trade routes that connected population centers of the Lower Yangzi Delta to timber supplies on China's southwestern frontier. She documents innovative property rights systems and economic incentives that convinced landowners to invest years in growing trees. Delving into rare archives to reconstruct business histories, she considers both the formal legal mechanisms and the informal interactions that helped balance economic profit with environmental management. Of driving concern were questions of sustainability: How to maintain a reliable source of timber across decades and centuries? And how to sustain a business network across a thousand miles? This carefully constructed study makes a major contribution to Chinese economic and environmental history and to world-historical discourses on resource management, early modern commercialization, and sustainable development.




Boston in Transit


Book Description

A richly illustrated story of public transit in one of America’s most historic cities, from public ferry and horse-drawn carriage to the MBTA. A lively tour of public transportation in Boston over the years, Boston in Transit maps the complete history of the modes of transportation that have kept the city moving and expanding since its founding in 1630—from the simple ferry serving an English settlement to the expansive network of the Massachusetts Bay Transportation Authority, or MBTA. The story of public transit in Boston—once dubbed the Hub of the Universe—is a journey through the history of the American metropolis. With a remarkable collection of maps and architectural and engineering drawings at hand, Steven Beaucher launches his account from the landing where English colonists established that first ferry, carrying passengers between what is now Boston’s North End and Charlestown—and sparing them what had been a two-day walk around Boston Harbor. In the 1700s, horse-drawn coaches appeared on the scene, connecting Boston and Cambridge, with the bigger, better Omnibus soon to follow. From horse-drawn coaches, horse-drawn railways evolved, making way for the electric streetcar networks that allowed the city’s early suburbs to sprout—culminating in the multimodal, regional public transportation network in place in Boston today. With photographs, brochures, pamphlets, guidebooks, timetables, and tickets, Boston in Transit creates a complete picture of the everyday experience of public transportation through the centuries. At once a practical reference, local history, and travelogue, this book will be cherished by armchair tourists, day-trippers, and serious travelers alike.

Wood & Beer


Book Description

Join authors Dick Cantwell and Peter Bouckaert as they tell the story of the marriage between wood and beer from Roman times through medieval Europe to modern craft brewing. Cooperage is a long and venerable craft and here the authors give a description combining the evocative and technical. The smells, the heat, choosing the wood, drying, fashioning staves, steaming, firing, and assembling into a perfect container—at least perfect until the bunghole is drilled to accommodate the precious contents. Barrels and foeders have gone from an oddity of traditional breweries to a commonplace feature at the heart of the craft brewing industry. It is estimated that 85% of US breweries now use wood as part of their process. Maintaining wooden vessels requires care and meticulous organization of cellar space. The authors discuss the vagaries of temperature, humidity, seasonal changes, mold, and evaporation, and how breweries new and old deal with these challenges. The basics of selecting, inspecting, cleaning, and maintaining barrels are detailed. Finally, of course, the wood must be united with the beer. The complexity and variations that govern how wood imparts flavors to beer can be overwhelming. The authors guide the reader through wood's characteristic flavor compounds and the nuances of toasting and charring. Oak is the focus, American, French, and Eastern European, but other woods get their due. As well as intrinsic flavors, the microflora that take up residence in a barrel or foeder are the living, beating heart of a barrel-aged beer, able to create sour and unique beers of fascinating complexity. The authors pepper the text with stories and experiences from some of the giants of the craft brewing scene, discussing how they monitor their barrel programs and taste and blend their beers to create something truly special. All this will inspire professional and amateur brewers alike. At the end of the book the authors give some helpful advice on wood aging for homebrewers, including the uses for chips, cubes, spirals, staves, powders ... and the odd chair leg. Get ready to embrace the mystical complexity of flavors and aromas derived from wood.

Wood


Book Description

Ötzi the iceman could not do without wood when he was climbing his Alpine glacier, nor could medieval cathedral-builders or today's construction companies. From time immemorial, the skill of the human hand has developed by working wood, so much so that we might say that the handling of wood is a basic element in the history of the human body. The fear of a future wood famine became a panic in the 18th century and sparked the beginnings of modern environmentalism. This book traces the cultural history of wood and offers a highly original account of the connection between the raw material and the human beings who benefit from it. Even more, it shows that wood can provide a key for a better understanding of history, of the pecularities as well as the varieties of cultures, of a co-evolution of nature and culture, and even of the rise and fall of great powers. Beginning with Stone Age hunters, it follows the twists and turns of the story through the Middle Ages and the Industrial Revolution to the global society of the twenty-first century, in which wood is undergoing a varied and unexpected renaissance. Radkau is sceptical of claims that wood is about to disappear, arguing that such claims are self-serving arguments promoted by interest groups to secure cheaper access to, and control over, wood resources. The whole forest and timber industry often strikes the outsider as a world unto itself, a hermetically sealed black box, but when we lift the lid on this box, as Radkau does here, we will be surprised by what we find within. Wide-ranging and accessible, this rich historical analysis of one of our most cherished natural resources will find a wide readership.
