"With the rise of the gramophone circa 1900, the shellac disc mushroomed into the dominant sound format of the first half of the twentieth century. Format Friction brings together a set of local encounters with the shellac disc, beginning with its preconditions in South Asian knowledge and labor as well as early colonial expeditions to capture sounds, to offer a global portrait of this format. Spun at 78 revolutions per minute, the shellac disc had become an industrial standard, even while the gramophone itself remained a novelty. The very basis of this early sound reproduction technology was friction, an elemental materiality of sound shaped through cultural practice. Yet the recording of sounds was only one element in the making of this global format. Using friction as a lens, Gavin Williams reveals the environments plundered, the materials seized, the ears entangled. Bringing together material, political, and music history, Format Friction decenters the story of a beloved medium and so too explores new ways of understanding listening in technological culture more broadly"--

Avalanche dynamics equations are used to estimate flow heights, velocities, specific thrust pressure, maximum specific weight of avalanche debris, and runout distance for 12 avalanche case studies from the Colorado Rocky Mountains. Suggestions are made for using this engineering approach for avalanche zoning and land use planning.

Pneumatic conveying is one of the most popular methods of handling bulk powdered and granular materials in mining, chemical and agricultural industries. This 3rd edition of this successful book covers both theoretical and practical aspects of the subject. It is unique in its blending of academic materials and good industrial design techniques. Each topic is covered in depth, with emphasis placed on the latest techniques, hardware systems and design and research methodology. Its comprehensive worked examples and table ensure that the reader need not consult any other reference material. In this 3rd edition new sections on simulation and modelling have been added, while the use of tomography as a tool for monitoring pneumatic conveying is also covered.

Giving you the first comprehensive presentation of the ground breaking research undertaken at Heriot Watt University, with Research Council and industrial funding, this book brings a new perspective to the design of building drainage and vent systems. It provides the building services community with clear and verifiable design methods that will be robust enough to meet challenges such as climate change and water conservation; population migration to the mega cities of the developing world, and the consequent pressures of user concentration; the rise of the prestige building and the introduction of new appliances and control strategies. These all combine to make traditional codified design guidance insufficient. Many assumptions in existing codes defining the entrained airflows within building drainage vent systems cannot be theoretically supported, so designers concerned with these systems need analysis and simulation capabilities which are at least as reliable as those enjoyed by other building services practitioners. The Method of Characteristics solution techniques which are well established in the pressure surge field are now used to provide solutions for drainage designers. The material is applied to a whole range of abstract scenarios then to a series of real world applications including the forensic modelling of the SARS virus spread within Amoy Gardens in 2003 and the refurbishment of the O2 Dome. Applications to specialised services, including underground station drainage and highly infectious disease treatment facilities are discussed and demonstrated, alongside the use of design and simulation techniques in support of product development. Aimed at both professional and academic users, this book serves both as a design aid and as a core text for specialist masters courses in public health and building services engineering.

When the four of us decided to collaborate to write this book on pneumatic conveying, there were two aspects which were of some concern. Firstly, how could four people, who live on four different continents, write a book on a fairly complex subject with such wide lines of communications? Secondly, there was the problem that two of the authors are chemical engineers. It has been noted that the majority of chemical engineers who work in the field of pneumatic conveying research have spent most of their time considering flow in vertical pipes. As such, there was some concern that the book might be biased towards vertical pneumatic conveying and that the horizontal aspects (which are clearly the most difficult!) would be somewhat neglected. We hope that you, as the reader, are going to be satisfied with the fact that you have a truly international dissertation on pneumatic conveying and, also, that there is an even spread between the theoretical and practical aspects of pneumatic conveying technology.
