    Description / Table of Contents: Summary On 27 June 1899 Rudolf Virchow (1821–1902) inaugurated the Museum of Pathology at the Charité Hospital. The collection comprised 23 500 pathologic-anatomical specimens. Most of the collection was destroyed in World War II. About 2000 samples were saved. Meanwhile the stock has increased to about 9000 objects. The development, contents and structure of the famous Virchow Collection are described with special reference to craniofacial deformities.
    Notes: Zusammenfassung Am 27. Juni 1899 eröffnete Rudolf Virchow (1821–1902) das Pathologische Museum der Charité. Die Sammlung umfaßte 23500 pathologisch-anatomische Präparate. Im Zweiten Weltkrieg wurde der größte Teil der Sammlung zerstört. 2000 Präparate konnten gerettet werden. Inzwischen ist der Restbestand wieder auf 9000 Objekte angewachsen. In der vorliegenden Arbeit werden die Entwicklung, der Inhalt und der Aufbau der berühmten Virchow-Sammlung unter besonderer Beachtung kraniofazialer Fehlbildungen und anderer „Monstrositäten“ beschrieben.

    Notes: Abstract The rate of pyrolysis and oxidation of 8 different samples of oil shale kerogen concentrate (KC) were investigated using DSC analysis. Recently performed thermogravimetric studies (TG and DTG) with the same samples of KC indicated that the activation energy of the pyrolysis of specific KCs increases with increasing paraffinic structure in the KC. An opposite effect, i.e. a decrease of the activation energy with an increase of paraffinic structure was determined in the case of KC oxidation. In this study, using the standard ASTM E-698 method based on the determined temperature at which the maximum heat effect could be observed (exo in the case of oxidation and endo in the case of pyrolysis), an activation energy for the pyrolysis, as well as for the oxidation process was determined and also successfully correlated with the content of paraffinic structure of KC. Thus, the higher content of paraffinic structure in KCs indicates that higher values of the activation energy could be determined either in the case of pyrolysis or oxidation followed by DSC analysis.
