This study examined microcrystals formed by silver with gamma-hydroxybutyric acid (GHB) and gamma-hydroxyvaleric acid (GHV), the five-carbon analog of GHB, in the presence of silver, copper, and lanthanide nitrates. Distinct microcrystals formed with silver (+1) and lanthanum (+3) ions but not with the copper (+2) ions. The crystals formed with GHB were distinctly different than those formed with GHV and in all cases, the drug microcrystals were easily distinguishable from reagent crystals. X-ray diffraction analysis provided definitive structure for the microcrystals. The morphological differences between the silver-GHB and silver-GHV crystals were characterized using simple measurements such as size and angles provided by image recognition software. The utility of the test for casework was demonstrated using spiked beverage samples. 相似文献

In 1976, the Pennsylvania legislature passed a new mental health law which was designed to give civil and due process rights to the mentally ill, as well as to speed up the deinstitutionalization process. The psychiatric profession voiced loud disapproval of the new law. The public interest bar entered the issue, opposing the psychiatrists. In 1978, the law was amended, and most of the hard-won patients' rights were lost. This paper analyzes the reasons behind the psychiatric demand and victory, as well as the reasons for the lawyer's unsuccessful opposition, using two similar battles, one fought in the British Parliament in the eighteenth century, and one in the California legislature in the early twentieth century. Conclusions are drawn concerning the reason for the legislative “turnabout,” and predictions concerning the course of future battles are made. 相似文献

We address the patent/antitrust conflict in licensing and developthree guiding principles for deciding acceptable terms of license.Profit neutrality holds that patent rewards should not dependon the rightholders ability to work the patent himself.Derived reward holds that the patentholders profits shouldbe earned, if at all, from the social value created by the invention.Minimalism holds that licenses should not be more restrictivethan necessary to achieve neutrality. We argue that these principlesare economically sound and rationalize some key decisions ofthe twentieth century such as General Electric and Line Material. 相似文献

In recent years, the Paris club granted a number of African countries, including Nigeria, debt relief. This elicited widespread celebration in the capital cities of affected countries, where it was portrayed as a veritable launch-pad to Africa's development. This paper takes a critical look at the debt relief, with emphasis on its problems and prospects for Africa's development. It is argued that while debt relief does offer some prospects for development, there is little or no evidence to suggest that such an outcome is automatic. The conditions that precipitated the debt crisis in the first instance, including an inequitable international economic order and political conditions tied to aid, are still very present in the debt relief regime. Corruption of the foreign aid regime by both internal and external actors has been compounded by the recent global economic crisis, posing further constraints on the effectiveness of foreign aid in Africa. If debt relief must yield the desired result, it has to be accompanied by a sustainable campaign to fundamentally reform the world order to make it more equitable, together with a drive for good governance that is not only democratic, but also efficient and development-oriented in Africa. 相似文献

Alignment with Europe has been a popular foreign policy objective among post-socialist nations. In the Republic of Georgia, discourse surrounding the country’s Euro-Atlantic orientation surged in the decade after the 2003 Rose Revolution. While such discourse has been examined in the context of political reforms and national security goals, this article foregrounds how it was incorporated into alterations of the built environment. Focusing on the urban transformations of the city of Batumi after the rise to power of the United National Movement government, it demonstrates how architecture served as a tool for selectively rewriting Georgia’s contemporary European identity. This article concentrates on two parallel initiatives to transform Batumi into a contemporary European city: the reconstruction of portions of the Old City and the new development along the seaside boulevard. Using evidence collected through qualitative methods, it further highlights the contradictions that emerged during this process of redevelopment and rebranding, as the state balanced initiatives for new development with other post-revolutionary state-building objectives, such as political reform and tourism-market production. Accordingly, it unpacks the various national and international politico-economic forces at play in the process of developing Batumi into the image of a contemporary European city. 相似文献

This paper describes two analytical techniques used to separate and quantify gamma-hydroxybutyrate (GHB) and gamma-hydroxyvalerate (GHV). The first technique was a N,O-bis(trimethylsilyl)triflouro-acetimide-trimethylchlorosilane derivatization, followed by gas chromatography/mass spectrometry analysis using an HP-5 capillary column at a rate of 1.0 mL/min with a run time of 9.25 min. This technique was found to be sensitive (LOD 1 pg on column) and gave a low average error (5%) in a beverage study. When supplemented by a surrogate spike, the method yielded 97% analyte recovery from beverages. The second technique was high-performance liquid chromatography/UV (HPLC/UV) using a C-18 column with a (20:80% v/v) methanol:dibasic phosphoric buffer (10 mM, pH 3) at a rate of 1.00 mL/min with a run time of 7.5 min. UV detection occurred at 254 nm. This method was found to be less sensitive (LOD 0.05 microg on column) for direct analysis of aqueous samples. To remove interferences seen in the beverage study, a liquid-liquid extraction before HPLC analysis was tested. However, a decreased sensitivity (LOD 100 microg on column) and irreproducible peak profiles resulted. 相似文献

Application of low copy number STR typing to the identification of aged, degraded skeletal remains 总被引:1,自引:0,他引:1

Low copy number (LCN) STR typing was successfully applied to four interesting cases during developmental validation of the approach for degraded skeletal remains. Specific questions were addressed in each case, with the acquisition of STR data largely serving as additional confirmatory or investigatory information in any specific situation, and not necessarily providing the definitive evidence to establish identity. The cases involve missing U.S. service members from World War I, World War II, and the Vietnam War. The variety of these cases, in terms of the questions addressed, the age of the remains, and the type of reference material available for comparison, demonstrates the broad utility of LCN STR typing in the identification of degraded skeletal remains from missing persons. 相似文献

This experiment tested the ability of undergraduate mock jurors (N=295) to draw appropriate conclusions from statistical data on the diagnostic value of forensic evidence. Jurors read a summary of a homicide trial in which the key evidence was a bullet lead "match" that was either highly diagnostic, non-diagnostic, or of unknown diagnostic value. There was also a control condition in which the forensic "match" was not presented. The results indicate that jurors as a group used the statistics appropriately to distinguish diagnostic from non-diagnostic forensic evidence, giving considerable weight to the former and little or no weight to the latter. However, this effect was attributable to responses of a subset of jurors who expressed confidence in their ability to use statistical data. Jurors who lacked confidence in their statistical ability failed to distinguish highly diagnostic from non-diagnostic forensic evidence; they gave no weight to the forensic evidence regardless of its diagnostic value. Confident jurors also gave more weight to evidence of unknown diagnostic value. Theoretical and legal implications are discussed. 相似文献
