The combined application of the four spectrometric techniques UV, IR, NMR and MS is an important analytical tool for the identification of the increasing number of potential poisons with which the analysts in the fields of forensic sciences and toxicology are confronted. Some of the contributions of these techniques to toxicological analyses are reviewed and illustrated by a few examples. Furthermore, the incorporation of the four methods into the analytical scheme, the requirements with respect to quantity and purity of the unkown substances, as well as the different possibilities for the combination of separation and identification techniques are outlined. 相似文献

Prerequisities for fractures of the neural arch of the axis in the region of the isthmus (hangman's fracture) during hanging are considered to be a long drop and a submental knot. A case is presented showing that hangman's fracture arising in hanging can result from stretching of the neck combined with anteroflexion of the head. 相似文献

The literature on the rational PBC suggests that politicians systematically manipulate economic and fiscal conditions before elections to increase their chances of reelection. Most tests of this theory look for evidence of pre-election distortions in fiscal policy. We propose a new test that explores the two-way interaction between the magnitude of the opportunistic distortion and the margin of victory. The test is implemented using a large panel of Portuguese municipalities. The results show that opportunism leads to a larger win-margin for the incumbent and that incumbents behave more opportunistically when their win-margin is small. These results are consistent with the theoretical model. 相似文献

This article examines the issues of censorship, language and racism through a critical reflection on Peter Tatchell’s response
to the critique of gay imperialism offered by Jin Haritaworn, Tamsila Tauqir and Esra Erdem. In ‘Academics smear Peter Tatchell’,
we are invited to find evidence of ‘Islamophobia, racism or support for imperialist wars’ in the writings that can be downloaded
from Tatchell’s website. The article shows how islamophobia and racism operate in Tatchell’s writings not necessary in the
content of specific arguments but through the very form of proximities (for example in the proximity between the words ‘Islam’,
‘fundamentalism’ and ‘terror’). The article thus reflects on how racism operates in language through the repetition of associations
that get ‘stuck’. 相似文献
