In the current study the objective was to find to what extent a reliable determination of age at death is made possible by establishing the degree of aspartic acid racemization in the dentin of teeth. The results of the investigation of 46 teeth are in agreement with the values found by other authors. The method presented makes a reproducible and accurate estimation of age possible. We intend to elaborate and improve this promising method for determination of age at death. The relevant points are presented here.  相似文献

This article explores the development of inter-American Catholicism during the 1950s and 1960s. It analyses the role of the Chilean Catholic bishop Manuel Larraín (1900–1966) in his efforts to disseminate his diagnosis of underdevelopment in Latin America and to establish links with the Catholic world in the United States. Based on a review of his writings, the American press and documentation from Catholic organisations, it is suggested that the Chilean bishop advocated the implementation of social reforms and American collaboration to prevent the advance of communism and strengthen Catholicism on the continent.  相似文献

The authors compared the effects of alcoholic drinks rich in fusel oil with the effects of diluted pure alcohol of the same quantity on 19 clinically healthy university students. The investigations utilized EEG and physiopsychic testing methods. The clinical symptoms were observed both under the effect of drinks and in a crapulous state ("hang-over"). It was found that alcoholic drinks rich in fusel oil can produce a more deviating EEG curve, an increased worsening of physiopsychic performance and of clinical and subjective symptoms. The necessity of regular quality control of alcoholic beverages is pointed out.  相似文献

Skull identification by electronic photo-composition can, with the help of a video-animation compositor, be further developed beyond the pure superprojection technique into an animated picture difference image. The employment of this combined technique to be recommended on account of the improved possibilities of control to be realized in the congruity of the superprojection composite picture.  相似文献

The photographic identification of a skull through the well-known superprojection technique can be modified and decisively improved by the use of a video-tape system. The identification method based on electronic photo composition is methodically simple to use. It offers the examiner the possibility to recognize the relationship between bone and soft part proportions, and the structure of the bone surface and the details of the soft part shape, as a concrete, tangible characteristic of identity to a substantially greater extent. The large number of controllable characteristics inherent in the ihgh degree of individuality of the skull offers not just an either/or "The skull fits"/ "It does not fit" into a photograph, but achieves proof of disproof of identity.  相似文献
