"Why do so many Americans drive for miles each autumn to buy a vegetable that they are unlikely to eat? While most people around the world eat pumpkin throughout the year, North Americans reserve it for holiday pies and other desserts that celebrate the harvest season and the rural past. They decorate their houses with pumpkins every autumn and welcome Halloween trick-or-treaters with elaborately carved jack-o'-lanterns. Towns hold annual pumpkin festivals featuring giant pumpkins and carving contests, even though few have any historic ties to the crop.In this fascinating cultural and natural history, Cindy Ott tells the story of the pumpkin. Beginning with the myth of the first Thanksgiving, she shows how Americans have used the pumpkin to fulfull their desire to maintain connections to nature and to the family farm of lore, and, ironically, how small farms and rural communities have been revitalized in the process. And while the pumpkin has inspired American myths and traditions, the pumpkin itself has changed because of the ways people have perceived, valued, and used it. Pumpkin is a smart and lively study of the deep meanings hidden in common things and their power to make profound changes in the world around us. Cindy Ott is assistant professor of American Studies at Saint Louis University."From the symbolism of pumpkins in classical and medieval mythology, to locavores and harvest festivals, Ott's paean to pumpkins is important, entertaining, and enlightening." -Warren Belasco, author of Food, the Key Concepts"An original, carefully researched, engagingly written, even playful and witty foray into the exploding field of food history by an up-and-coming star in the field. How appropriate that so delightful a vegetable has an equally delightful book to pay it tribute." -from the Foreword by William Cronon"--

Acid mine drainage is one of the biggest environmental issues facing mining companies today. Government agencies, the general public and mine owners require that potential for acid generation can be predicted and controlled with a high degree of confidence. Failure to satisfy these concerns about acid mine drainage can slow the approval and permitting process delaying the start of production at the mine and considerably adding to the cost of mine development. These costs can be reduced by selection of predictive testing procedures appropriate to the level of mine development which will answer immediate environmental concerns in the context of the mine plan and indicate whether further testing is required. We present a procedure for the prediction of acid generation which integrates the stages of deposit exploration and approval for mine development with suitable predictive testwork to determine the potential for acid generation, the rate of acid production and suitable acid control techniques. ; Non UBC ; Unreviewed ; Other
