Authoritative review of composition, structure and evolution of the mantle for researchers and graduate students.

Many geochemists focus on natural systems with less emphasis on the human impact on those systems. Environmental chemists frequently approach their subject with less consideration of the historical record than geoscientists. The field of environmental geochemistry combines these approaches to address questions about the natural environment and anthropogenic effects on it. Eby provides students with a solid foundation in basic aqueous geochemistry before discussing the important role carbon compounds, isotopes, and minerals play in environmental issues. He then guides students through how these concepts apply to problems facing our atmosphere, continental lands, and oceans. Rather than broadly discussing a variety of environmental problems, the author focuses on principles throughout the text, leading students to understand processes and how knowledge of those processes can be applied to environmental problem solving. A wide variety of case studies and quantitative problems accompany each chapter, giving each instructor the flexibility to tailor the material to his/her course. Many problems have no single correct answer, illustrating the analytical nature of solving real-world environmental problems.

Describes the efforts of the Jackson Elementary School in Everett, Washington, to clean up a nearby stream, stock it with salmon, and preserve it as an unpolluted place where the salmon could return to spawn.

Launched in 1939, the Civilian Pilot Training Program (CPTP) was one of the largest government-sponsored vocational education programs of its time. In To Fill the Skies with Pilots, Dominick A. Pisano explores the successes and failures of the program, from its conception as a hybrid civilian-military mandate in peacetime, through the war years, and into the immediate postwar period. As originally conceived, the CPTP would serve both war-preparedness goals and New Deal economic ends. Using the facilities of colleges, universities, and commercial flying schools, the CPTP was designed to provide a pool of civilian pilots for military service in the event of war. The program also sought to give an economic boost to the light-plane industry and the network of small airports and support services associated with civilian aviation. As Pisano demonstrates, the CPTP's multiple objectives ultimately contributed to its demise. Although the program did train tens of thousands of pilots who later flew during the war (mostly in noncombat missions), military leaders faulted the project for not being more in line with specific recruitment and training needs. After attempting to adjust to these needs, the CPTP then faced a difficult and ultimately unsuccessful transition back to civilian purposes in the postwar era. By charting the history of the CPTP, Pisano sheds new light on the politics of aviation during these pivotal years as well as on civil-military relations and New Deal policy making.

Seit über 50 Jahren gehört die Massenspektrometrie zu den wichtigsten analytischen Methoden. Neben einem technologiehistorischen Überblick konzentriert sich dieser Band auf die Analytik von Metallen und Elementen. Beschrieben werden Anwendungen aus der Meteorologie, Kerntechnik, Astrochemie, Geowissenschaft und Umwelttechnik. Dabei wird auf zahlreiche spezielle Verfahren eingegangen, u.a. auf die Sektorfeld- und die Sekundärionen-MS, auf induktiv gekoppelte Plasmen und beschleunigergestützte MS. Erläutert werden auch Isotopenverfahren zur Altersbestimmung von Proben.

Set in a small Australian farming town on the edge of a national park, Jake and the PB's is an exciting tale of adventure for boys and girls between the ages of 7 and 11 years. A sequel to the ever-popular Jake's Secret, the book tells the story of Jake and his best mate, Sam, Ricky, the class nerd, Tom, the school bully, and Janey, the girl next door; a group of ordinary kids with extraordinary super-powers. Joined by their friend Chadwick, a colorful magic elf with a large, round, yellow face, Jake and his "PB's" take magical powder that shrinks them in size, allowing them to fit inside a hovering, flying car that travels back and forth through time. Dedicated to the motto "Protect and Assist," the group of friends travels forward in time in an effort to save a habitat of koalas that are at risk from a local farmer who wants to clear his land. Discover what other exciting adventures await Jake and his friends, as they career through time, trying to return to their own era, before the effects of the magical powder wear off! Glynis Bloomfield grew up in a small farming town in Victoria, Australia and now lives in the beautiful seaside city of Warrnambool in southwest Victoria.
