A study of fatal poisoning due to alcohol and drugs was carried out, to examine the mortality resulting from alcohol and drugs in the Greater Amman County, Jordan. A retrospective review of all autopsy records and certified deaths issued by the Department of Forensic Medicine at Jordan University Hospital in the greater Amman county was undertaken. During the 18 years (1978-1996) 6109 postmortem cases were performed in our department. A total of 60 cases were identified and analyzed according to age, race, sex, manner of death of the victims along with blood alcohol concentration, the drug detected at autopsies, the scene circumstances, and the geographic location of the accident and death. 相似文献

The cross-reaction of anti-delta 1-THCA MAb against other cannabinoids was very wide. However, other naturally occurring and synthetic phenolics including opium alkaloids did not react to the MAb. Using this ELISA, this paper reports application of the competitive ELISA for detection of marijuana samples. The ELISA described here was very sensitive to the ether extracts of marijuana samples when compared to those of other plants. The assay provided a sensitive method useful for the judge of marijuana samples. 相似文献

The Reference National Laboratory, Genes Ltda, designated by the Commission of Accreditation and Alertness created by Law 721 of 2001 of Republic of Colombia, organized and coordinated the Quality Control Exercise of 2008 for laboratories undertaking paternity and maternity tests with DNA markers. The Quality Control Exercise included both practical and theoretical exercises. For the practical exercise, three blood samples in FTA Classic Card were sent to each participating laboratory to be genotyped for DNA markers using the routine methodologies in their laboratories. For the theoretical exercise, it was asked to the participating laboratories to calculate the partial and final paternity indexes based on two genetic profiles of an alleged biological father and his son. Allele frequencies were made available to the participants, as well as Y chromosome haplotype database. A total of 12 laboratories have participated with data from 57 STRs, including autosomal and sex chromosome markers. Consensus was found in 37 STRs, 21 in autosomes and 16 Y chromosome linked. The rate of reporting errors was 3.1% (concentrated in just one laboratory). The theoretical exercise had consensus. 相似文献

To maintain public safety and improve system response, a strong need exists for understanding the contexts of and police response to weapon-related incidents as well as socio-economic variables of individuals involved. This paper was focused on exploring these contexts and routine police activities by creating and analyzing a weapon-related database at the local level. The findings, although limited due to the explorative nature of the study and the quality of case files, shed some interesting light on the effects of environmental and operational variables on gun incidents and expose certain issues that need to be resolved before further and more accurate understanding of gun crimes at the local level can be achieved. 相似文献

目的 考察纤维屑在涉及二次转移案件中作为示踪物质的适用性.方法 根据一个实际案例展开,在该案中,犯罪嫌疑人涉嫌多起入室盗窃案.纤维开始分散于嫌疑人所用车辆,后被嫌疑人“携带”并分散到犯罪现场,最终这些纤维在勘查过程中被收集.设计完善了一个可用于散布纤维的便携式装置,并完成了一系列二次转移的相关实验.结果 设计的装置可在短时间均相的散布纤维,单次接触不能全部转移第一表面的纤维碎屑.只有1-15%的纤维会转移到代表犯罪现场的第三表面.实际转移的纤维数与包括比如表面的材质在内的各种因素都有关系.结论 在所选参数范围内,相对大量的纤维有可能转移到犯罪现场并在现场勘查过程中被提取. 相似文献

To evaluate postmortem intervals (PMIs), one should take into account the determined age of necrophagous flies present on the cadaver. However, PMI determination needs further improvement, and rapid and accurate approaches have therefore to be developed. While previous studies have focussed on insect cuticular hydrocarbons, here we explore the volatile profile released by larvae and pupae of Calliphora vicina Robineau-Desvoidy (Diptera: Calliphoridae). We monitored changes in volatile compounds daily, by headspace solid-phase microextraction, followed by gas chromatography-mass spectrometry. Branched and unbranched hydrocarbons, alcohols, esters and acids were identified, and the volatile profile was shown to vary, in both composition and quantity, with the age of the larva/pupa under investigation. We concluded, based on the analysis of the released volatile organic compounds, that it is possible to increase the accuracy of the estimated PMI, through improved estimation of the age of blowflies present on the cadaver. 相似文献

Unlike some of its Western counterparts, where the first line of defence against corruption and unethical behavior has been a reliance on a public service ethos, the Hong Kong government has traditionally relied on strict compliance with rules and regulations in its successful drive against bureaucratic malpractices. Since 1997, however, a changing political, economic and administrative environment has also seen efforts to introduce a more value-based approach to integrity. This article examines the factors that have led to the modification of the Hong Kong government??s strategy and evaluates its success in the wider theoretical context of the relationship between a predominantly rule-based and a value-based approach to integrity management. 相似文献

Using a 2004 population-based survey of all US medical examiner and coroner offices, we examined the characteristics of offices accepting an infant death case and calculated the percentage of offices that had death scene investigation or autopsy policies for the investigation of sudden unexpected infant death (SUID). We also calculated the percentage of offices that used and did not use sudden infant death syndrome (SIDS) as a cause of death, and we compared differences in characteristics among those offices.Of medical examiner and coroner offices, 52% did not report an infant death in 2004. Of the 7957 infant deaths reported, 43% occurred in jurisdictions that experienced 1 or 2 infant deaths. Of the offices that used SIDS as a classification, 34% did not have policies for conducting death scene investigations and autopsies for SUID. At least 5% of offices that reported an infant death did not use SIDS as a cause of death classification. These findings have important implications for understanding recent trends in SIDS and SUID. Supporting the implementation of national standards for investigating and certifying infant deaths could provide guidelines for consistent practices in medical examiner and coroner offices. 相似文献
