Minimaler Aufwand bei der Probenvorbereitung, hoher Informationsgehalt des Spektrums und die Möglichkeit, mit festen Proben zu arbeiten, machen die Raman-Spektroskopie zunehmend attraktiv. Wie man diese Methode mit modernster Ausrüstung effizient anwendet, zeigt Ihnen das vorliegende Buch. Im Mittelpunkt stehen neue Entwicklungen wie CCDs, Diodenlaser und Fourier-Transform-Techniken. Behandelt werden auch quantitative Analysen, die in der bisher vorhandenen Literatur häufig zu kurz kamen. (08/00)
This volume provides a practical, intuitive approach to electroanalytical chemistry, presenting fundamental concepts and experimental techniques without the use of technical jargon or unnecessarily extensive mathematics. This edition offers new material on ways of preparing and using microelectrodes, the processes that govern the voltammetric behavior of microelectrodes, methods for characterizing chemically modified electrodes, electrochemical studies at reduced temperatures, and more. The authors cover such topics as analog instrumentation, overcoming solution resistance with stability and grace in potentiostatic circuits, conductivity and conductometry, electrochemical cells, carbon electrodes, film electrodes, microelectrodes, chemically modified electrodes, mercury electrodes, and solvents and supporting electrolytes.
Ever since British soldiers returning from India in the mid-nineteenth century introduced their homeland to a fast-paced ball game on horseback, polo has remained the quintessential British sport. Although its origins lie in Asia, British pioneers are credited with both modernizing the game and spurring its spread worldwide. This volume chronicles the history of polo in the British Isles from its beginnings in the 1860s through the summer of 2011. It recounts the development of polo clubs, including the rise and fall of once mighty citadels of the game; describes the major competitions and many of the lesser tournaments in England and Ireland; and gives particular attention to international contests. Biographical sketches of top players, from early innovators to current superstars, and reflections on current issues affecting the game, including the rise of commercialism and the decrease of civility and sportsmanship, complete this vivid panorama of British polo.
In this autobiography, Omar N. Bradley (1893-1981) recounts his youth in Missouri, his years at the US Military Academy at West Point (he graduated in 1915 alongside Dwight D. Eisenhower), his assignments on the US-Mexico border and in Montana guarding copper mines during World War I, his tours teaching mathematics at West Point and in 1941, commanding of the US Army Infantry School at Fort Benning, his active duty during World War II in North Africa, Sicily, Normandy and eventually commanding 43 divisions and 1.3 million Americans in Europe, linking up with Soviet forces on the Elbe in April 1945, sealing the defeat of Nazi forces. Bradley provides vivid descriptions of key figures in the l...
Tracing the evolution of polo from its origins in Central Asia to its current manifestation as a professional sport that attracts wealthy sponsors and patrons, this sociological study examines how polo has changed according to the economic and cultural differences of the nations and continents where it is played. One hundred historic and modern photographs are included.
Throughout Appalachia corporations control local economies and absentee ownership of land makes it difficult for communities to protect their waterways, mountains, and forests. Yet among all this uncertainty are committed citizens who have organized themselves to confront both external power holders and often their own local, state, and federal agents. Determined to make their voice heard and to improve their living conditions, newfound partnerships between community activists and faculty and students at community colleges and universities have formed to challenge powerful bureaucratic infrastructures and to protect local ecosystems and communities. Confronting Ecological Crisis: University ...
