This book provides an up-to-date review of the effects of increasing atmospheric carbon dioxide on agroecosystems, forests, and grasslands. It summarizes the main findings from 13 experiments with annual crops, permanent pastures and plantation forests at 11 sites throughout the world during the past ten years. The results significantly alter our perception of how rising CO2 will directly affect these managed ecosystems.

Managed ecosystems cover a large part of the Earth's land surface, provide almost all of our food and most of our wood and fibre, and are increasingly a source of renewable energy. Forecasting the ability of managed ecosystems to continue these vital roles in a globally changing environment is an inter-disciplinary challenge.

To elucidate the complex responses of managed systems to elevated CO2], several free air carbon dioxide enrichment (FACE) facilities were established. These FACE systems allow large areas to be exposed to the elevated CO2] we expect by the middle of the century. This volume summarizes the main findings from 13 experiments with annual crops, permanent pastures and plantation forests at 11 sites throughout the world during the past ten years. The results significantly alter our perception of how rising CO2] will directly affect these managed ecosystems, with implications for policy, plant-breeding objectives and adaptation.

The Book of Runes is something very special: a part of the ancient past and, perhaps, a part of your future...
Based on a tradition over one thousand years old, the Runes are seen by many as a contemporary Oracle and collectively, have established themselves as a remarkable aid in practical decision making.
A huge success with over 900,000 copies sold, since its original publication in 1983, "The Book of Runes "has proved to be a modern classic. For this, the 25th anniversary of the work, Ralph H. Blum has expanded and refined the runic system, making the Runes one of the most profoundly useful self-help tools of the new century.

Die Zielsetzung dieser Arbeit bestand in der Berechnung von Beruhr- und Detailproblemen an weggebundenen Zweistanderpres- sen. Zur rechnerischen Berucksichtigung der Beruhreffekte zwischen an- grenzenden Bauteilen wurde ein benutzerfreundliches Rechner- programm entwickelt, das sich in den Berechnungsgang einer FE-Berechnung einfugen lasst. Testrechnungen an verschiedenen Beispielen haben die Vorgehensweise verdeutlicht und im Falle der uberprufung mit den Hertzschen Formeln eine gute uberein- stimmung ergeben. Die Berucksichtigung der Beruhreffekte war auch bei den Problemen Pleuel-Exzenterrad, Stoessel-Fuhrung und Welle-Lager, die z. T. als Detailprobleme behandelt wurden, von grosser Bedeutung, um ein realistisches Bauteileverhalten zu erreichen. In Abhangigkeit von der Belastung ergibt sich ein nichtlineares Bauteileverhalten. Die Untersuchung eines Pressenrahmens mit Stoessel ergab hier die Moeglichkeit, auch die Auswirkungen der Klemmkrafte zwischen Stoessel und Fuhrung bei exzentrischer Arbeitsbelastung zu analy- sieren. Es zeigte sich, dass es nur durch die Einbeziehung der Beruhreffekte in die gesamte FE-Berechnung moeglich war, reali- stische Pressenkennwerte zu errechnen. Eine grosse Rolle spielte hierbei Gesamtkonstruktion dargestellt. An einer typischen Ausfuhrung einer Zweistanderpresse mit Langs- wellenantrieb wurde das Detailproblem Welle-Lager behandelt.

Brewed in Detroit describes the history of the brewing industry in the Detroit metropolitan area (including Ann Arbor, Mt. Clemens, Pontiac, Windsor, Wyandotte, and Ypsilanti) from its beginning in the 1830s to the present revival by microbrewers and brewpubs.

A historian and trained veteran of the brewing industry, Peter H. Blum divides Detroit brewing history into seven distinct phases: the early Anglo-Saxon ale brewers, the German brewers who arrived after 1848, the rise of brewing dynasties in the 1880s, Prohibition, the return of beer in the era after repeal in 1933, the war years, and the post-war competition. Blum also includes detailed information on the way beer is produced -- the craft of brewing and the tradition of master brewers.

Brewed in Detroit tells the story of the Stroh Brewery Company, which was a family brewery in Detroit from 1850 to 1985 and became Detroit's largest brewery by the turn of the century. Blum then chronicles the stories of forty-three individual Detroit breweries in small groups of similar ethnic or economic units, describes breweries in the six surrounding cities, and tells of H.W. Rickel & Company, the preeminent local malt producer.

Each brewery's story is told in terms of the individuals and families who started the enterprise, and chronicles their fortunes and failures. There are about 180 photographs of brewers, buildings, wagons and trucks, equipment, and advertising to illustrate the various chapters. A special feature is sixteen color pages of brewery advertising, including rare lithographs from the Stroh archives, made possible through a gift from the Stroh Brewery Company.

The book concludes with a compilation of every brewery inDetroit of which there is a record, brand names of all beers and ales marketed in Detroit, production figures of all Detroit breweries since 1933, a glossary of technical terms, and an index.
