Postmortem changes in sulfide concentrations in body tissues were examined in autopsied rats exposed to hydrogen sulfide concentrations of 550 to 650 ppm, and in nonexposed rats and humans. Analyses were made by gas chromatography, following an extractive alkylation. Sulfide concentrations in the blood, liver, and kidneys of rats increased in both the exposed and nonexposed groups, depending on the lapse of time after death. On the other hand, the lung, brain, and muscle showed little or no change in sulfide concentration with elapse of time after death. The data obtained from human tissues were almost the same as those for rats, except data for blood, in which no or little increase of sulfide was observed. 相似文献

We develop a model of the peace dividend and use it to predict the fiscal consequences of a reduction in the demand for military spending. The model is based on the assumption that the political process responds to political demands and costs in a way that maximizes net political benefits. The predictions of our model on how a peace dividend will be allocated over nonmilitary spending, tax relief, and deficit reduction is tested against the experience of eight major wars in United States history. 相似文献

A case of kidnapping involving the concept of paternity testing is described. The couple arrested and charged with kidnapping stated the child in their possession was their biological daughter. Serological tests were performed on liquid blood samples in an effort to determine if the couple could have been the biological parents of the child. Two genetic inconsistencies were discovered in the 15 blood marker systems analyzed. 相似文献

By the eighteenth century the colonial powers in Europe already had well-defined images and self-images, crystalised from their native cultures, their significance within Europe, and their mercantile and political relations with other continents. Yet Germany, which would have no prospect of a unified polity till late in the following century, remained severely challenged in all these respects. From the mid eighteenth century, however, Germany’s greatest minds sought to mould for it a cultural identity, and as a vital step in this, the poet, statesman and scientist Goethe, a man indebted to a form of patronage which peculiarly qualified him to undertake such experiments, conducted a series of literary encounters with the great traditions of Asia. Their purpose was to situate Germany within the wider world culture, for one can only be a cultural force within a world to which one has some cultural relation. Goethe’s forays into the worlds of Persian, Indian and Chinese literature were attempts at creative imitation, cultural absorption and public confrontation, but their culture-building and appropriative character was also a form of vicarious imperialism, a new-world enterprise conducted by means of old-world patronage. Goethe’s carefully nuanced representations in the West-Eastern Divan indicate the advocacy of a secular cosmopolitanism, the popular impact of which has been hitherto underestimated. 相似文献

An important problem in the political economy of the UK is that the disparity of unemployment rates across its regions is much more marked than the corresponding dispersion of wage rates. One possibility is that this is due to the attitude of trade unions to their members in different regions. If unions wish to preserve parity between members in different regions then they will value wage equality between regions over and above wage levels. This may then persuade them to overlook inter-regional productivity differences in setting wages. The price that low-efficiency regions will then pay for this desire for wage equality is higher unemployment rates.Much of the research for this paper was carried out while the author was visiting the Trade Union Economics Research Institute (FIEF), Stockholm in 1989. An earlier version of this paper was presented at a seminar there and the author is gratefully to Villy Bergstrom, Paul Chen, Douglas Hibbs, Eva Udden-Jondal and other institute members for several useful comments. Comments from Kevin Lee, John Spencer and an anonymous referee have also substantially improved the paper. The usual disclaimer applies. 相似文献
