Coal remains one of the principal sources of energy for the United States, and the nation has been a world leader in coal production for more than 100 years. According to U.S. Energy Information Administration projections to 2050, coal is expected to be an important energy resource for the United States. Additionally, metallurgical coal used in steel production remains an important national commodity. However, coal production, like all other conventional mining activities, creates dust in the workplace. Respirable coal mine dust (RCMD) comprises the size fraction of airborne particles in underground mines that can be inhaled by miners and deposited in the distal airways and gas-exchange regi...

This volume is the eleventh in a series which documents the technical papers of the mine ventilation symposium, which was initiated in 1982 by the Underground Ventilation Committee of the Society for Mining, Metallurgy, and Exploration, Inc. In more recent years, the event has expanded to include all of North America and is known as the US/North Am
Das zweibändige Handbuch ist die erste umfassende Gesamtdarstellung der literarischen Verarbeitung von "Wende" und deutscher "Einheit". Band I informiert zunächst ausführlich über den sich nach 1989 rapide verändernden Literaturbetrieb, sprachliche Aspekte der "Wende" und wesentliche Feuilletondebatten. Im Zentrum stehen exemplarische Analysen wichtiger Essays, Tagebücher und Autobiografien, Protokolle, Erzählungen, Romane, Gedichte und Dramen u.a. von Christa Wolf, Volker Braun, Brigitte Burmeister, Christoph Hein. Weitere Kapitel setzen sich mit dem Phänomen der "Ostalgie", Figuren wie "IM", "Ossi" und "Wessi", häufig wiederkehrenden Metaphern und Motiven sowie intertextuellen Beziehungen auseinander. Band II enthält die bisher umfangreichste thematisch ausgerichtete Bibliografie von Primär- und Sekundärtexten. Durch die systematische Betrachtung von Texten aller Gattungen wird das bisherige Bild der sogenannten "Wendeliteratur" in vielerlei Hinsicht korrigiert und erweitert.
