The analysis of naphthenic acid revealed that they may be used for tin detection in the cadaveric material due to their high complex-forming ability. Method of extraction-atomic absorption tin determination in human organs was developed on the basis of naphthenic acid use. Modified method which differs from the common one by higher sensitivity and selectivity is presented.  相似文献

Quadratic pieces of fleece measuring 16 mm2 were soaked with 10 different blood-samples in the dilution steps of 1:1, 1:10, 1:100, 1:1000, respectively, and were tested in blood group typing and identification tests of forensic serology. The above spezified dilutions correspond with 5 microliters, 0.5 microliter, 0.05 microliter and 0.005 microliter of blood, respectively. The detection limit of the microspectrometric test for blood was the dilution 1:10, of the porphyrine test a dilution above 1:100, whereas the preliminary test for blood (peroxidase) succeeded always up to a dilution of 1:1000 and the species determination by the radial immunodiffusion test in agar gels succeeded in most cases op to a dilution of 1:1000. The detection limit of the anti-human globulin inhibition test was between the dilution steps 1:10 and 1:100 when non-titrated and undiluted anti-human globulin serum was used. Gc- and ABO-grouping were possible up to a dilution of 1:100 and were thus the most sensitive grouping systems. Phenotyping of the enzyme-systems and the Gm/Km-system usually required stains with considerably higher blood concentrations i.e. stains of undiluted blood.  相似文献

The purpose of this study is to review 23 causes of death that have occurred in Western-Austrian prisons from 1974 to 1989. The majority of them (11 cases) were due to suicides. Among 9 cases of natural death there was a 25 years old man, who died of an unknown purulent meningoencephalitis. Two drunken prisoners had not been supervised and therefore died of alcohol poisoning. In one case the police jail physician did not recognize an epidural hematoma.  相似文献

This paper addresses the changing role of the Portuguese state, the present priority assigned to the process of reform and the new challenges to be overcome by public administration. Such processes are demanding a new agenda for education and research in public administration sciences, shifting from the public law paradigm to an interdisciplinary problem‐solving approach and giving special attention to 10 key areas of study, which we describe in the final section of the paper. It should be noted here that the opinions expressed in this paper do not necessarily reflect the position of their institutions.  相似文献

This paper gives the author's impressions on the following aspects of justice: desert, equity, equality, need, and intergenerational equity. The author concludes that these different aspects cannot be reconciled but instead must be compromised. An example of such a compromise is provided by a discussion of welfare reform. The author claims that rights are correlative with duties, and that asserting the former has little meaning without specifying the latter. He then discusses justice toward groups rather than individuals. He proposes that maintaining cultural variety in the presence of a homogeneous superculture is a major problem of the contemporary world. The paper concludes with a discussion of various forms of power, particularly the integrative power that people acquire over each other by virtue of ties of loyalty and identity.  相似文献

Dr. Wilton Marion Krogman was one of the major founders of physical and forensic anthropology in the United States. His extraordinary career spanned nearly six decades, and he was universally admired and respected for his scholarship, teaching, research, wit, and humanity. While studies based on human skeletal remains have long been used to assist the medicolegal system, the late Dr. Krogman can be credited with uniting these areas into the discipline of forensic anthropology. His "Guide to the Identification of Human Skeletal Material" (1939) in the F.B.I. Law Enforcement Bulletin became the foundation of this discipline; his monumental book The Human Skeleton in Forensic Medicine (updated with the author in 1986) solidified its establishment. The purpose of this paper is to pay tribute to this great man and outline his influence on the development and advancement of forensic anthropology.  相似文献
