Jack London was an American author, journalist, and social activist. A pioneer in the then-burgeoning world of commercial magazine fiction, he was one of the first fiction writers to obtain worldwide celebrity and a large fortune from his fiction alone. Some of his most famous works include The Call of the Wild and White Fang, both set in the Klondike Gold Rush, as well as the short stories "To Build a Fire," "An Odyssey of the North," and "Love of Life." He also wrote of the South Pacific in such stories as "The Pearls of Parlay" and "The Heathen," and of the San Francisco Bay area in The Sea Wolf. London was part of the radical literary group, "The Crowd," in San Francisco, and a passionate advocate of unionization, socialism, and the rights of workers. He wrote several powerful works dealing with these topics, such as his dystopian novel The Iron Heel, his non-fiction expose The People of the Abyss, and The War of the Classes."
Historical Geography of Crop Plants is devoted to a variety of staple and food crops, as well as fodder, fiber, timber, rubber, and other crops. The origins and histories of many of these crops have been clarified only recently by new research. The book has been arranged alphabetically by family and higher taxa for easy reference. Within families, species and cultivars are listed chronologically and geographically. The taxonomy and geography of probable wild progenitors have been outlined, and archeological evidence (when available) and historical evidence on region and domestication are traced. The subsequent evolution and spread of many domesticated species are examined, and the reasons behind the diversity in crop histories are explored. Historical Geography of Crop Plants will be a useful reference for botanists, economic botanists, ethnobiologists, agronomists, geographers, and others interested in the subject.

Monitoring and predictive maintenance methods are not reliable enough in indicating certain important problems in manufacturing equipment, such as cracking of power transmission components, inadequate lubrication of parts, and excessive cutting edge wear of a tool or die. These problems are best dealt with at the design stage. Plant and Machinery Failure Prevention is based on the premise of “Zero-Failure Performance”. The book introduces the general features and investigative methods at the design phase for determining failures in mechanical components such as: Flat Belt Failures, Vee-belt Failures, Pulley Failures, Gear Failures, Steel Wire Rope Failures, Spring Failures, and Gasket Failures.
