An international community of specialists reinvented the propeller during the Aeronautical Revolution, a vibrant period of innovation in North America and Europe from World War I to the end of World War II. They experienced both success and failure as they created competing designs that enabled increasingly sophisticated and 'modern' commercial and military aircraft to climb quicker and cruise faster using less power. Reinventing the Propeller nimbly moves from the minds of these inventors to their drawing boards, workshops, research and development facilities, and factories, and then shows us how their work performed in the air, both commercially and militarily. Reinventing the Propeller documents this story of a forgotten technology to reveal new perspectives on engineering, research and development, design, and the multi-layered social, cultural, financial, commercial, industrial, and military infrastructure of aviation.

Hydraulic machinery such as turbines and pumps is widely used around the world. Related topics concerning design, operation and maintenance are of relevant interest. In this context, cavitation is a phenomenon to be taken into account, and this was treated in the XVIII IAHR Symposium on Hydraulic Machinery and Cavitation which took place in Valencia, Spain, 16th-19th September, 1996 and which was hosted by the Polytechnic University of Valencia. The proceedings of the Symposium have been published in two volumes. In this first volume, the papers included cover the following topics: Hydraulic Turbines, Analysis and Design Hydraulic Pumps Hydraulic Elements, Dynamic Characterization and Hydraulic Behaviour Cavitation and Sand Erosion In the second volume, the papers included cover the following topics: Hydraulic Transients and Control Systems Related to Hydraulic Machinery and Plants Oscillatory and Vibration Problems in Hydraulic Machinery and Power Stations Experimental Investigations related to Hydraulic Machinery and its Applications Practical Applications of the Hydraulic Machinery Monitoring, Predictive Maintenance and Refurbishment The 119 papers presented at the Symposium, from research groups, consulting companies and manufacturers, constitute an important collection for investigators, engineers and technicians who are interested in updated information on hydraulic machinery. This book is intended to be a reference text comprising the latest innovations on this subject.

England's controversial #1 best-seller. What brings a child to kill another child? In 1968, at age eleven, Mary Bell was tried and convicted of murdering two small boys in Newcastle upon Tyne, England. Gitta Sereny, who covered the sensational trial, never believed the characterization of Bell as the incarnation of evil, the bad seed personified. If we are ever to understand the pressures that lead children to commit serious crimes, Sereny felt, only those children, as adults, can enlighten us. Twenty-seven years after her conviction, Mary Bell agreed to talk to Sereny about her harrowing childhood, her terrible acts, her public trial, and her years of imprisonment-to talk about what was done to her and what she did, who she was and who she became. Nothing Bell says is intended as an excuse for her crimes. But her devastating story forces us to ponder society's responsibility for children at the breaking point, whether in Newcastle, Arkansas, or Oregon. A masterpiece of wisdom and sympathy, Gitta Sereny's wrenching portrait of a girl's damaged childhood and a woman's fight for moral regeneration urgently calls on us to hear the cries of all children at risk.

The twelfth-century French poet Chrétien de Troyes is a major figure in European literature. His courtly romances fathered the Arthurian tradition and influenced countless other poets in England as well as on the continent. Yet because of the difficulty of capturing his swift-moving style in translation, English-speaking audiences are largely unfamiliar with the pleasures of reading his poems. Now, for the first time, an experienced translator of medieval verse who is himself a poet provides a translation of Chrétien’s major poem, Yvain, in verse that fully and satisfyingly captures the movement, the sense, and the spirit of the Old French original. Yvain is a courtly romance with a moral tenor; it is ironic and sometimes bawdy; the poetry is crisp and vivid. In addition, the psychological and the socio-historical perceptions of the poem are of profound literary and historical importance, for it evokes the emotions and the values of a flourishing, vibrant medieval past.
