Images, Representations and Heritage : Moving beyond Modern Approaches to Archaeology
Recent archaeological theory has show that images of the past have carried a particularly strong resonance within modern social groups. This volume explores the immeasurable impact that the phenomenon of archaeology has had on the representation of the past in the modern world. Modern society’s ‘archaeological imagination’ conceives of archaeology as a producer of images of the past which become representations of modern group identities. If archaeology is utilized by public groups to construct and represent identities, then what are archaeologists to do with that public? The very fact that the public is interested in the past and in archaeological research is an opportunity for archaeology to engage that public.
Cold Micro Metal Forming : Research Report of the Collaborative Research Center “Micro Cold Forming” (SFB 747), Bremen, Germany
This book contains the research report of the Collaborative Research Center “Micro Cold Forming” (SFB 747) of the University of Bremen, Germany. The topical research focus lies on new methods and processes for a mastered mass production of micro parts which are smaller than 1mm (by forming in batch size higher than one million). The target audience primarily comprises research experts and practitioners in production engineering, but the book may also be of interest to graduate students alike.
Low Thermal Expansion Glass Ceramics
Describes the fundamental principles, the manufacturing process, and applications of low thermal expansion glass ceramics. The composition, structure, and stability of polycrystalline materials having a low thermal expansion are described, and it is shown how low thermal expansion glass ceramics can be manufactured from appropriately chosen glass compositions. Examples illustrate the formation of this type of glass ceramic by utilizing normal production processes together with controlled crystallization. Thus glass ceramics with thermal coefficients of expansion of less than 0.3 x 10(-6)K(-1) can be obtained. Even for the mass production of high-quality cooktop panels (Ceran®., oven windows, and other household appliances a high reproducibility of the properties is achieved. Special glass ceramics (Zerodur®. for technological and scientific applications such as high-precision optics or large astronomical mirrors are likewise discussed. The completely revised edition also features new sections on glass-ceramic applications, with details on their performance, CDC-grinding, and laser gyroscopes containing Zerodur®..
Advances in Life Cycle Engineering for Sustainable Manufacturing Businesses ; Proceedings of the 14th CIRP Conference on Life Cycle Engineering, Waseda University, Tokyo, Japan, June 11th-13th, 2007
Life cycle engineering deals with technologies for shifting the industry from mass production and mass consumption paradigm to closed loop manufacturing paradigm, in which required functions are provided for customers with the minimum amount of production. This subject is discussed from the various aspects, such as life cycle design, design for environment, reduce/reuse/recycle, life cycle assessment, and sustainable business models.Advances in Life Cycle Engineering for Sustainable Manufacturing Businesses gathers together papers from the 14th CIRP Life Cycle Engineering Conference. This conference is the longest running annual meeting in the field, in which papers are presented regarding developments of leading edge technologies, proposals of new concepts, and prominent industry case studies.
A Biomass Future for the North American Great Plains : Toward Sustainable Land Use and Mitigation of Greenhouse Warming
The Great Plains of North America is a major global breadbasket but its agriculture is stressed by drought, heat spells, damaging winds, soil erosion and declining ground water resources. This book explores the possibility that the ecology and economy of the Plains region (and similar regions) would benefit from the introduction of perennial biomass crops. Biomass production and processing on the Plains (possibly aided by genetic engineering) would partially restore a perennial vegetative cover and create new employment opportunities. Biomass also offers a means of reducing fossil fuel use, providing fuel to local power plants and a feedstock for production of cellulosic ethanol, a gasoline substitute. Interest in biofuels is growing rapidly in public, political and business circles with rising fossil fuel prices and because of a growing recognition of the need for energy independence in petroleum importing countries.
