The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization. 相似文献

Ownership and conditionality in IMF-supported programs: Back to Per Jacobsson’s time 总被引:1,自引:1,他引:0
Oscar Calvo-Gonzalez 《The Review of International Organizations》2007,2(4):329-343
Using a historical case study this article provides an example of how heterogeneity of interests within a government may affect the interplay between country ownership of reforms and conditionality in IMF-supported programs.
The case study also highlights how pro-reformers’ preferences may be conditional on reforms advancing their personal agendas.
This suggests a new issue to be addressed by formal models of conditionality. Two main themes emerge from the analysis: (a)
the importance of a clear hierarchy to unify heterogeneous interests among decision makers; and, (b) a flexible country-tailored
approach to conditionality can contribute to domestic ownership of reforms.

This paper describes the analytical methodology for the determination of MDMA, MDA, MDEA and MBDB in oral fluid. After a liquid–liquid extraction, the analysis was carried out by high performance liquid chromatography (HPLC), with fluorescence detection. The detector wavelength was fixed at 285 nm for excitation and 320 nm for emission. The mobile phase, a mixture of phosphate buffer (pH = 5) and acetonitrile (75:25), and the column, Kromasil 100 C8 5 μm 250 mm × 4.6 mm, allowed good separation of the compounds in an isocratic mode in only 10 min. The method was validated and showed good limits of detection (2 ng/mL) and quantitation (10 ng/mL) for all the amphetamine derivatives. No interfering substances were detected. A stability study of these compounds in oral fluid stored at three different temperatures (−18, 4 and 20 °C) over 10 weeks was conducted, showing a time-dependent degradation of the four compounds. 相似文献

AbstractAs the largest source of carbon-free energy in the United States, nuclear energy must play a vital role in reducing emissions. This article suggests the Green New Deal, an ambitious federal proposal to address climate change, should aim to preserve the existing nuclear fleet by authorizing states to establish zero emission credit (“ZEC”) programs. The ZEC programs will provide credits, in the form of revenue, for the carbon-free attribute of nuclear energy. This article posits the ZEC programs should be based on a model ZEC program developed by the Federal Energy Regulatory Commission and explicitly authorized by amendment of the Federal Power Act to avoid issues of preemption. 相似文献
