The impact of high temperatures (24 to 39 degrees C) and low to moderately high humidities (20 to 70%) on the applicability of TLC systems for drug identification was studied during a 6 month climatologic cycle in Burkina Faso (West Africa). In general, the Rf values as observed on the plates were found to be substantially affected as compared with values obtained at temperate climates. Some TLC systems were more affected than others and the largest deviations of up to 30 Rf units were at low humidities. Tropical conditions also had a negative effect on the reproducibility of Rf values. However, when an Rf-correction procedure was applied, using reference mixtures of known drugs on each plate, accuracy as well as reproducibility of the resulting Rfc values were drastically improved and data thus corrected were found to be compatible with existing TLC data bases developed under moderate climatological conditions. The impact of high to extremely high humidities (70 to 100%) remains to be investigated.  相似文献

In this study, a new method was developed for the impurity profiling of illicit MDMA tablets. The extraction efficiency, linearity, repeatability and reproducibility of the method were evaluated. Eighty two MDMA tablets coming from presumed unrelated large seizures in 2004 (n >500 tablets) were analyzed by gas chromatography mass spectrometry (GC-MS) in order to assess the discrimination power of the method. The latter was found to be practical, robust, relatively easy to perform, highly discriminative and yielding good chromatography. In addition, some new impurities were detected and identified. Their chemical structures and mass spectra are reported.  相似文献

The role of the state is changing under the impact of, for example, globalization. The changes have been variously understood as the new public management (NPM), the hollowing–out of the state and the new governance. This special issue of Public Administration explores the changing role of the state in advanced industrial democracies. It focuses on the puzzle of why states respond differently to common trends.
This introductory article has three aims. First, we provide a brief review of the existing literature on public sector reform to show that our approach is distinctive. We argue that the existing literature does not explore the ways in which governmental traditions shape reform. Second, we outline an interpretive approach to the analysis of public sector reform built on the notions of beliefs, traditions, dilemmas and narratives. We provide brief illustrations of these ideas drawn from the individual country articles. Finally, we outline the ground covered by all the chapters but we do not summarize and compare their experiences of reform. That task is reserved for the concluding article.  相似文献

This synoptic article focuses on the origin and functioning of the Office of the Family Advocate as the protector of the interests of minor children in divorce cases. Attention is paid to the general contemporary trend to specialise in judicial decision-making that developed out of an increasing need for expertise in the administration of justice. A number of arguments for and against judicial specialisation are addressed. The origin of the Office of the Family Advocate within the South African judicial system is discussed and a brief exposition of the history of divorce legislation in South Africa is given. This is followed by attention to the functioning of the Office of the Family Advocate with reference to the process followed in investigations of this office and points of criticism against the system are highlighted. The article closes with an indication of the need for research in this regard and possible focus points for future research are identified.  相似文献

In a case of suicidal application of electricity differences between the rectal temperature of the body and the suspected time of death were observed.In order to answer the question whether an electric current from hand to hand over >30 min led to a rise in body temperature FEM-based computer simulations and animal experiments were carried out. Both resulted in a warming of the soft parts in the arm without warming the body core. Thus a temperature-based estimation of the time since death can also be used in cases with electricity as the cause of death. Besides, in the animal experiment we found a spontaneous rise in the body core temperature even without application of electricity which may be a reason for the typical temperature plateau after death.  相似文献

Within the context of transboundary disputes, this paper seeks to determine which liability concept, negligence or strict liability, performs better when assets are secure against foreign claims for transboundary damages. Our results indicate that, if assets are hidden from foreign claims, strict liability will not implement the socially optimal outcome, but neither will negligence. However, even though the socially optimal outcome is not always achieved, strict liability weakly dominates negligence. These results suggest that the harmonization of statues that deal with transboundary pollution should be based on strict liability not negligence.

This article critically appraises the narrative of nationalist resurgence in China in the 1990s that structures much of the secondary literature on Chinese politics since Tiananmen. Adopting a post-structuralist method, Chinese texts from the 1990s are treated as discursive rather than as expressions of a common consensus, emergent ideology or political movement. This makes it possible to bring out the disparate points of view concerning the desirability of nationalism for China and to understand the strategies that are being deployed by authors within the context of everyday Chinese politics. It also reveals the significance of the absence from both the primary and the secondary texts of any mention of the advocacy of nationalism by the political leadership. When this hidden discourse is taken into account, it becomes evident that many of the texts that have been taken as expressions of a nationalist revival are either not particularly interested in nationalism or are highly sceptical concerning its possibilities for solving the problems faced by the Chinese state. Particularly significant is the way in which many of the texts locate themselves in relation to the official discourse on nationalism by appropriating its themes in order to promote and legitimate a wide range of other discourses with which it can be bound up, ranging from democracy to authoritarianism.  相似文献
