Abstract: With improvements in manufacturing procedures, comparing physical characteristics of paper samples may not offer sufficient discrimination among different vendors. In this work, the potential to differentiate paper samples based on trace element concentrations was investigated. Paper samples from two different vendors were microwave-digested and trace element concentrations (Mg, Al, Mn, Fe, Sr, Y, Ba, Ce, and Nd) were determined using inductively coupled plasma–mass spectrometry. Differences in concentration were assessed statistically using two-way ANOVA and Tukey's honestly significant differences test. Elemental concentrations were shown to be consistent across a single sheet as well as within a single ream of paper for each vendor. Reams from vendor A were differentiated based on Al and Ba concentration while reams from vendor B were differentiated based on Mg, Mn, and Sr concentrations. Paper was differentiated according to vendor based on significant differences in Ba, Sr, Ce, and Nd concentrations. 相似文献

The recent adoption of the new E-Money Directive by the Council of the European Union has introduced key changes to European e-money legislation. The adoption of the new directive follows the European Commission's review of the original e-money directive and the market that it was intended to facilitate, which found that e-money has yet to deliver the benefits that were anticipated. 相似文献

Fentanyl is an extremely potent narcotic analgesic that is becoming more popular as a drug of abuse. Because of the unique way in which the drug is packaged and delivered, the potential for unusual methods of abuse exists. We report the first case of true fentanyl patch ingestion in the medical literature. Initially, though unusual, cases of fentanyl ingestion were thought to have been reported, but further investigation of the literature revealed that in other case reports the patches had been held in the mouth and chewed. Because no reports of swallowing the patch had been published, suicide was initially a strong consideration in this case; however, further investigation showed that the decedent and his brother enjoyed swallowing the patches for quick "highs." Cases such as these serve to remind medical examiners and law enforcement officials of the value of performing thorough death investigations by performing complete autopsies with toxicological testing and correlating with investigation information to form an opinion with regard to the cause and manner of death. 相似文献

An actuarial tool, the Ontario Domestic Assault Risk Assessment (ODARA), predicts recidivism using only variables readily obtained by frontline police officers. Correctional settings permit more comprehensive assessments. In a subset of ODARA construction and cross-validation cases, 303 men with a police record for wife assault and a correctional system file, the VRAG, SARA, Danger Assessment, and DVSI also predicted recidivism, but the Hare Psychopathy Checklist (PCL-R) best improved prediction of recidivism, occurrence, frequency, severity, injury, and charges. In 346 new cases, ODARA and PCL-R independently predicted recidivism. An algorithm was derived for a combined instrument, the Domestic Violence Risk Appraisal Guide (DVRAG), and an experience table is presented (N=649). Results indicated the importance of antisociality in wife assault. 相似文献

This column examines the historical context in which the standard of health care offered to rural and remote communities has developed to become less than that afforded their metropolitan counterparts. In particular, it looks at the support offered to nurses working within these communities in terms of not only the lack of medical resources, including doctors, in these areas, but also the legal and professional restrictions placed on nurses that leave them feeling vulnerable to complaints of working outside their scope of practice. The column concludes with a discussion of the legal standard of care and ways in which nurses may adequately meet the health needs of their community while working within legal parameters. 相似文献

On 26 August 1975 the colonial administration in Portuguese Timor abruptly removed itself from Dili to the island of Atauru, amidst escalating armed conflict among Timorese political parties. A puzzle that has remained is why did the Portuguese administration leave so precipitately, and why did it not return a few days later when the conflict was over? We have been left with the impression that Portugal simply deserted its responsibilities, abandoning the territory to Indonesian annexation. This paper pieces together a rivetting but little-known story, from contemporary Portuguese, Indonesian, US, Australian, Timorese and eyewitness accounts, about the humiliating capture and detention by Timorese and Indonesians of Portuguese military as prisoners of war, which helps to explain a previously unrecognized constraint on Portuguese policy in East Timor in 1975-1976. This paper also shows that Indonesia had taken some important lessons from history on how to manage Portugal, from India's annexation of Portuguese Goa in 1961. 相似文献
