The word tribology was fIrst reported in a landmark report by P. Jost in 1966 (Lubrication (Tribology)--A Report on the Present Position and Industry's Needs, Department of Education and Science, HMSO, London). Tribology is the science and technology of two interacting surfaces in relative motion and of related subjects and practices. The popular equivalent is friction, wear and lubrication. The economic impact of the better understanding of tribology of two interacting surfaces in relative motion is known to be immense. Losses resulting from ignorance of tribology amount in the United States alone to about 6 percent of its GNP or about $200 billion dollars per year (1966), and approximately...
The Concubine's Daughter is a snapshot of a bygone era, depicting life in the British colony of Hong Kong in the fifties and sixties. It is the story Elizabeth Lee, beautiful, intelligent, and liberated, from the time she is a wide-eyed eighteen year-old studying English Literature at the University of Hong Kong, sharing girlish secrets with her two best friends, to her becoming an academic at the University, to just after her thirtieth birthday, when she leaves Hong Kong with her husband and young son for the US, frightened in part by the riots inspired by the Cultural Revolution taking place across the border in mainland China. After twenty years in the US she returns to Hong Kong in 1986,...
Plants have cultural histories, and their culturally known applications change through time and across contexts. This pattern is seen in all types of uses that humans make of plants, from trees used for construction, through species used for perfume through to food plants. However, it is medicinal plants that have attracted considerable attention recently, whether as a justification of plant conservation efforts or through the perception that direct use of medicinal plants may offer something that is not delivered by orthodox medicine. This volume's two central aims are to demonstrate that plant knowledge is not paradigmatic positive knowledge but situational and arises in relationships, and to show that modern medicinal plant discovery can be viewed as the epitome of a long history of borrowing, stealing, and exchanging plants.
The 14th International Conference on Wear of Materials took place in Washington, DC, USA, 30 March - 3 April 2003. These proceedings contain over two-hundred peer reviewed papers containing the best research, technical developments and engineering case studies from around the world. Biomaterials and nano-tribology receive special attention in this collection reflecting the general trends in the field. Further highlights include a focus on the new generation of instrumentation to probe wear at increasingly small scales. Approximately ninety communications and case studies, a popular format for the academic community have also been included, enabling the inclusion of the most up-to-date research. Over 200 peer-reviewed papers including hot topics such as biomaterials and nano-tribology Keeping you up-to-date with the latest research from leading experts Includes communications and case studies
