In conjunction with the Twelfth International Congress of Gerontology, the Carl-Korth Institute for Cardiovascular Research organized an international symposium on "Beta Blockers in the Elderly." It was the intention of the Scientific Committee that during this symposium we would discuss the specific problems and therapeutic implications arising when elderly people have to be treated with beta-blocking agents. Special emphasis was placed on the side effects and the age dependent features of beta-blocker therapy. Beta-blockers have become established in the treatment of both cardiovascular diseases and neuropsychiatric disorders. Their effectiveness in patients suffering from coronary heart disease, hypertension, and hyperkinetic cardiac syndromes has long been proven. The development of new, selectively active beta-blockers has substantially reduced the number of possible side effects, thus enhancing therapeutic safety. Because side effects cannot be eliminated, however, beta blockers have been introduced only hesitantly into treatment of the elderly. This book is the first wide-ranging survey of the use of beta blockers in elderly patients. The articles contained herei- written by pharmacologists, cardiologists, sports physicians, neurologists, psychiatrists, and ophthalmologists - show that advanced age alone does not contraindicate the use of beta-blockers and sympatholytic substances. Also provided are guidelines for examination and determination of in dications in the elderly. Both the symposium and the publication of this volume have been kindly supported by Astra Chemicals, West Germany.
Metals and alloys rely for their application at high temperature on the formation and retention of oxide scales, which act as a barrier between the metallic substrate and the reactive species in the environment such as 0, S, N, C, Cl, etc. This protection concept requires that the oxide grows slowly, develops a dense, uniform layer, is well adherent, has sufficient ductility to accom modate plastic deformation of the substrate and is resistant to thermal cycling. For many years it has been known that small concentrations of certain "active elements" such as Y and the rare earths, as well as carbon and sulphur, can exercise a significant influence upon the oxidation! corrosion behaviour of high temperature metals and alloys. An increasing number of experimental studies on this topic have been published recently. However no generally accepted understanding with regard to the detailed mechanisms and the way in which alloy composition and structure, temperature and environmental conditions, etc., are interacting has yet been achieved, although many - often controversial - theories and ideas have been presented. It therefore seemed to be an appropriate time to bring together a group of experts to review and evaluate the current state-of-the-art and to discuss various aspects of this important topic.
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.
