Cyanide concentrations of blood samples from fire victims autopsied in the Institute of Legal Medicine, Munich, have been determined. In 25% of 48 analyzed cases cyanide concentrations from 0.52 microgram to 6.24 microgram Cyanide/ml blood have been detected. These results are compared to former studies and the higher mean level in our collective is emphasized. The importance of hydrocyanid acid in the toxicity of fire gases is evidently greater, than assumed. Hydrocyanic acid may be produced from nitrogen continaing polymers during combustion. The quote of these polymers in clothing, furniture, and also in equipment of cars is increasing. Therefore, it is necessary to take more notice of the formation of hydrocyanic acid during combustion, even though carbon monoxide is in general the main toxic agent in fire gases. 相似文献

This paper is concerned with the impact of the Medical Device Amendments of 1976 and its implications in terms of innovation. With this objective the paper first describes the Medical Device Amendments of 1976. The paper then reports empirical evidence on the sources of a subset of innovations regulated by the Amendment's clinical chemistry diagnostic products. Finally, based on the pattern of innovations found, some thoughts are expressed about the likely effects of the Amendments. 相似文献

The Researchers' primary purpose was to explore relationships between (a) urban area secondary school teachers' assessments of thirty three sources of information apt to influence their practice and (b) specific characteristics of these teachers. A sample of 245 teachers, or 61% of the set contacted, participated. Qualitative and quantitative analyses of data offered by the respondents were carried out. Both predictable and perplexing outcomes of the data analyses were documented. The Researchers concluded: a) That demographic profiles of teachers can be discerned which are related to assessments of various information sources; and b) that teachers' needs for information can be linked to preferred sources of information. They were unable to explain why variables like years of teaching experience, sex, and age were related significantly to teachers' assessments of sources of information. 相似文献

Sommaire. Le gouvernement peut être défini comme la régulation des affaires publiques1 et à des fins d'analyse cette régulation, comme d'ailleurs les régulations privées, peut être distinpée en communication et en commandement. Pour que la régulation s'accomplisse, la communication doit être commandée, et le commandement communiqué. Nous nous situerons ici dans la première perspective:celle où la régulation est vue comme commandement de la communication. C'est la perspective de l'analyse politique, par opposition à une analyse davantage socio-économique qui se donnerait pour objet les phénomènes de communication eux-mêmes. Abstract. Government can be defined in terms of the regulation of public affairs. For purposes of analysis, public regulation, like private regulation, can be identified as communication and command. For regulation to be achieved, communication must be ordered and the order communicated. Here we will explore the first notion, the consideration of regulation as ordering communication. This is the viewpoint of political analysis, as opposed to a more socio-economical analysis which is concerned with the phenomena of communication itself. 相似文献
