Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfängen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen für die historische wie auch die disziplingeschichtliche Forschung zur Verfügung, die jeweils im historischen Kontext betrachtet werden müssen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.

An International Symposium "Catecholamines and the Heart" was held in Munich in May 1981, which was organized in cooperation with the Council on Cardiac Metabolism of the International Society and Federation of Cardiology and with the Microcirculation Working Group of the European Society of Cardiology. It was the aim of the organizers to evaluate in this Symposium the recent advances made in the field of sympathetic control of heart function. Particular attention was given to neural sympathetic pathways, to mechanisms and consequences of adrenoceptor stimulation and blockade as well as to clinically relevant implications mainly regarding the significance of catecholamines and of adrenoceptors in various heart diseases. The broad scope was covered in 34 papers presented by physiologists, pharmacologists and cardiologists during a two day meeting which was attended by an international audience. This book includes all papers as well as the discussions following each presentation. To accomplish rapid publication the manuscripts are published as submitted by the authors. The discussions were edited making use of the written questions and answers of the discussants. The Symposium was generously sponsored by Astra Chemicals GmbH, Wedell Holstein, Germany, which thus made possible a very fruitful exchange of information, ideas and concepts between specialists in various disciplines. The organizers gratefully acknowledge this support once again and would like to thank Dr. T. Kreuzer, the representative of Astra Chemicals, for his personal engagement.

Conferences on the Physics of Selenium and Tellurium were held in 1964 in London, 1967 in Montreal, and eight years ago, 1971, in Pont-a-Mousson. The last conference was noteworthy because of two facts: For crystalline Te and Se a high level of results was achieved and, further, it was possible to outline the focal points for continuing research work. These points were mainly to explore. the electronic structure of trigonal Se and Te and of the hypothetic~l cubic limit of these materials. To im­ plement such study, progress in band structure calculations was necessary. In addition, a consistent analytical description of the bands near the va­ lence band conduction band gap was required with the aim to understand the semiconducting properties, mainly magnetotransport and magnetooptical ef­ fects of band electrons and of impurities. Further questions concerned the influence of defects, such as dislocations, on transport properties and, finally, a concluding description of lattice dynamics of trigonal Se and Te, based on theoretical and experimental work, such as neutron diffraction and optical measurements. Besides the listing of this future research program it became obvious that more detailed work on the amorphous state of solids and liquids was necessary in order to improve our knowledge about their crystalline proper­ ties, growing conditions. and all problems of chemical bonds.
