Ernst Koch – författare

Luthertum und Musik – das ist seit dem 16. Jahrhundert eine Grundsignatur von Kirche und Kultur. Im Gefolge der Reformation entwickelte sich eine reichhaltige und vielfältige lutherische Musikkultur. Heinrich Schütz und Johann Sebastian Bach haben sie in ihren Zeiten und bis in die Gegenwart besonders kräftig bestimmt. Die Aufsätze dieses Bandes handeln von den theologischen und frömmigkeitsgeschichtlichen Kontexten ihrer Werke, spüren ihren Entstehungsbedingungen nach und fragen nach dem Zusammenhang von Irdischem und Himmlischem.Eine Laudatio und eine Bibliographie der Schriften von Ernst Koch erschließen das reichhaltige Werk eines Kirchenhistorikers, dem es immer auch um den Zusammenhang von Musik und Theologie zu tun war und ist.[Music of Humans and Music of Angels. Contributions to Lutheran Music Culture in the History of Piety]Lutheranism and music – this has been a basic signature of church and culture since the 16th century. In the wake of the Reformation, a rich and diverse Lutheran musical culture developed. Heinrich Schütz and Johann Sebastian Bach have had a particularly strong influence on it in their times and up to the present day. The essays in this volume deal with the theological and piety-historical contexts of their works, trace the conditions under which they were written and ask about the connection between the earthly and the heavenly.A laudation and a bibliography of the writings of Ernst Koch open up the rich work of a church historian who has always been and still is concerned with the connection between music and theology.

r*AENDERUNG URHEBER

The present voLume describes the chemicaL behavior of eLementaL tungsten toward the non- metaLlic eLements nitrogen to arsenic (i.e., N, F, CL, Sr, I, S, Se, Te, Po, S, C, Si, P, and As). The description of the chemicaL behavior starts with information on the phase diagrams wh ich aLLow an overview of the existing stabLe compounds. The major part of the information in this voLume is about the kinds of products, the experimentaL conditions, as weLL as the kinetics and thermodynamics of their formation. Short descriptions of buLk diffusion in binary systems compLement the kinetic data on the mostLy diffusion-controLLed reactions. Pure surface phenomena on tungsten are not considered. A Large chapter is devoted to the comprehensiveLy studied chemicaL processes and trans- port processes in tungsten-haLogen Lamps. Product formation in the tungsten-carbon and tungsten-silicon systems is aLso of speciaL interest in view of possibLe appLications. The present voLume concLudes the series of voLumes devoted to the chemicaL behavior of eLementaL tungsten. Interactions and reactions with nobLe gases, hydrogen, and oxygen are covered in "Wolfram" Erg.-Sd. S 1.Interactions and reactions with metaLlic eLements are described in "Tungsten" SuppL. VoL. A 6a (eLements antimony to barium) and in "Tungsten" SuppL. VoL. A 6 b (eLements zinc to actinides).

The present volume continues the description of the chemical reactions of eiemental tungsten started with "Tungsten" Suppl. Vol. A 7. It covers the reactions with the metallic elements from zinc to actinoids. The treatment includes phase diagrams, bulk reactions, and surface processes which again are of outstanding importance in most systems. The raader is referred to the introductory remarks on pp. X/XI.
