Reference material was synthesised for 21 substances that are frequently present as synthetic impurities, i.e. by-products, in illicitly produced amphetamine. Each of these substances is a typical by-product for at least one of the three approaches most often used to synthesise amphetamine, namely, the Leuckart, the reductive amination of benzyl methyl ketone, and the nitrostyrene routes. A large body of data on the substances was recorded, including the following: mass spectra, ultraviolet spectra, Fourier transform infrared spectra, infrared spectra in gas phase, and 1H NMR and 13C NMR spectra. 相似文献
The present study focused on the stability of 22 amphetamine impurities dissolved in six organic solvents: isooctane, toluene, ethanol, dichloromethane, ethyl acetate, and diethyl ether. The aim was to find the most inert, and thereby most suitable, solvent for amphetamine profiling. Mixtures of the impurities were prepared in the different solvents, and changes in the concentrations of the individual compounds over-time were monitored by gas chromatographic analysis after 0, 4, 12, 24, 48, and 96 h. Isooctane and toluene provided the most inert conditions, although, a few of the impurities were insufficiently stable in these two solvents. The present experiments were performed as a part of the development of a harmonized method for profiling of amphetamine. The results can be used to support the choice of organic solvents for sample preparation. They also provide information about the stability of the impurities that are found in profiles of illicit amphetamine. This is essential due to the fact, that unstable compounds can have a negative influence on the comparison of profiles. 相似文献
For the last forty years, remittances have been a lifeline for some Filipinos in times of crisis as well as everyday life. So, it was no surprise when the media and nongovernmental organizations credited the Philippine diaspora with playing a significant role in post-disaster recovery after Typhoon Haiyan/Yolanda struck in 2013. While remittances poured in after this disaster, they were differently experienced, had different impacts, and led to uneven post-disaster outcomes. This article highlights the class-based inequalities that structure access to and mobilization of remittances after post-disaster recovery. We compare the experiences of middle- and lower-class households in three communities heavily affected by Haiyan in Tacloban City, Philippines, to investigate who benefitted and who was excluded from remittances in this post-disaster recovery. The findings of the case study shed light on wider issues of poverty, class, and vulnerability in the Philippines. 相似文献

Federalism has proved enduring in Australia, despite predictions of its imminent demise. Yet new challenges of internationalism and social movements are cutting across old political boundaries and eroding the sovereign nation state. This article, which draws on ideas developed at length in my recent book A Federal Republic: Australia's Constitutional System of Government (Cambridge University Press, 1995), argues that the characteristics of federalism may prove surprisingly compatible with social and international trends. 相似文献
Successive Australian Labor governments have tried to nationalizestandards for the protection of rights either by means of astatutory bill binding on the states under the Commonwealth'smuch expanded external affairs power, or by further entrenchingspecific rights in the Constitution. All these attempts havefailed for a variety of political and constitutional reasonsincluding, importantly, the strength of Australia's establishedsystem of federalism and parliamentary responsible government.The article examines the constitutional issues underlying thedebate over a bill of rights for Australia, arguing that Labor'sattempts to implement a bill of rights have been inspired bya preference for more centralized government whereas the defeatof such initiatives indicates, the established strength of Australianfederalism. 相似文献
ABSTRACTIntergovernmental councils in Germany comprise 18 sectoral ministerial conferences and the prime ministerial conference as peak organization. They complement the Bundesrat as institutions of Intergovernmental Relations in the German system of cooperative federalism, dealing with matters of shared rule as well as self-rule. Based on expert interviews among ministerial bureaucrats, this contribution finds that contrary to conventional wisdom, vertical influence and autonomy protection are not their main purpose. Rather, they serve primarily information exchange and coordination. Still, the emphasis on either influence and autonomy protection or coordination and information as well as the directions of interaction vary across policy sectors. We further investigate constitutional allocation of power and party political composition as determinants on the specific purpose of ministerial conferences. The findings suggest that the allocation of power is more important than party political composition in explaining variation between sectoral ministerial conferences. 相似文献
