Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - The last major conference on infrared astronomy was the IAU Symposium No. 96 in June 1980. Since then, the discipline has continued to mature and to contribute to all branches of astrophysics. One particular area of growth has been in spectroscopi…c capabilities at all infrared wavelengths. The purpose of the Symposium in Toledo was to review the scientific questions to be addressed via infrared spectroscopy and to provide, in the proceedings, a useful summary of the field. The sensitivity of infrared spectroscopic observations is still generally limited by detector characteristics or by thermal background radiation. However in recent years improvements in detector technology together with developments in spectroscopic instrumentation have made possible both quite detailed spectroscopy of the brighter members of many classes of galactic sources and also begun to open up some infrared spectroscopy of extragalactic sources. The potential of the field in the next decade or two is clear. The lRAS mission has completed one of the pre-requisites, namely an all-sky photometric survey. Major space missions utilising cryogenic infrared telescopes have been approved in Europe (ISO) and seem likely in the USA (SIRTF); plans for space submillimeter telescopes are firming up. On the ground large telescopes optimized for infrared observations are now in operation at high altitude sites and specialized submillimeter facilities are under construction. The particular advantages of planned, very large telescopes for infrared observations are widely accepted.

Hardcover. Condizione: gut. Auflage: 1 (20. März 2002). Bestimmte Konstitutionstypen werden in der homöopathischen Praxis häufiger indiziert als andere. Diese oft verordneten Mittel werden als Polychreste bezeichnet und sind somit Arzneimittel mit einem besonders großen Anwendungsbereich. In den drei Bänden von Catherine Coulter…s "Portraits homöopathischer Arzneimittel" werden ausgewählte Polychreste nicht in der neutralen, wissenschaftlichen Sprache, sondern -wie Hahnemann es forderte - in der Sprache der betroffenen Patienten dargestellt. Mit Hilfe der Beschreibung von berühmten Persönlichkeiten und bekannten Charakteren aus Geschichte und Literatur werden diese Typen herausgearbeitet und veranschaulicht. Dadurch wird es dem verordneten Arzt leicht gemacht, anhand der beschriebenen Symptome und Empfindungen, die Individualität und Persönlichkeit des Patienten zu erkennen und das Verständnis für dessen Wissen zu vertiefen.

(Natur & Heilen)"Dieses Buch stellt in der Reihe der unverzichtbaren Standardwerke eine echte Ergänzung und Bereicherung dar." (Erfahrungsheilkunde) Band III Aurum metallicum Thuja Causticum Graphites Vergleichende Materia medicaHellsehen Misstrauen Großzügigkeit Gleichgültigkeit In diesem dritten Band greift die Autorin den Ansatz er vergleichenden Materia Medica für einige Themenbereiche ganz gezielt auf und arbeitet so unter anderem neue Aspekte vertrauter Polychreste heraus und hilft dem Therapeuten seine persönlichen Erfahrungen zu organisieren und zu überprüfen. RezensionDie amerikanische Homöopathin Catherine R. Coulter stellt in ihren drei Bänden "Portraits homöopathischer Arzneimittel" auf sehr interessante Art und Weise die Polychreste (= Mittel die besonders oft verordnet werden und mit großem Anwendungsbereich) vor. Es ist hervorragend geeignet für jeden Homöopathen aber auch interessierten Laien, der sich etwas tiefer in die Materie einlesen möchte. Die Portraits der Mittel sind humorvoll und facettenreich dargestellt. Man kann nachvollziehen wie Homöopathie entstanden ist und wie man in Mitteln "denkt". Es lässt sich flüssig lesen und wird dabei nie langweilig, schon aufgrund der zahlreichen Fallbeispiele an berühmten Personen. Im dritten Band steht die vergleichende Materia Medica für einige Themenbereiche (Hellsehen, Misstrauen etc.) im Vordergrund. Alle drei Werke sind allerdings nicht geeignet um Akutmittel zu finden, sondern eher um sein Wissen um die Konstitutionstypen zu vertiefen. Natürlich ist es nicht das einzige was man zur Mittelwahl zu Rate ziehen sollte, aber als tätiger Homöopath sollte man einfach so viel wie möglich lesen und vergleichen um ein "vollständig und rundes Bild" von jedem Mittel zu bekommen. Als solches sind diese drei Werke unendlich wertvoll.C. R. Coulter, Portraits Homöopathischer Arzneimittel, Bd. III. Stuttgart Haug, 2002. Karl F.
