A 33-year old hobby pyrotechnician sustained a lethal craniofacial trauma secondary to a salute fireworks blast. He was examining a misfire of a self-constructed salute gun, when it detonated, causing an explosively rupture of his forehead, which led to his immediate death. An autopsy was performed to achieve knowledge of the injury and to be able to reconstruct the events that lead to it. The pressure effect of the explosion caused a shredded rupture of the forehead with a regional spread of brain tissue and small polygonal skull fragments up to 30m from the detonation site. Furthermore multiple cinderlike fragments of black powder were embedded in the skin of the face and the anterior aspect of the neck (s.c. blast tattoo). The complete destruction of the forehead in combination with the multiple blast tattooing suggested that the explosion detonated while he was leaning over the device. 相似文献

Normally, the identification of the LSD drug is performed by forensic laboratories, using the Ehrlich spot test. However, this is a nonspecific analysis. Additionally, the Brazilian Federal Police has identified the presence of a new compound in seized blotters: 9,10-dihydro-LSD, an uncontrolled substance. In this work, easy ambient sonic-spray ionization mass spectrometry in the positive ion mode, EASI(+)-MS, was used to characterize LSD and 9,10-dihydro-LSD compositions directly from the surface of blotters. The presence of LSD in the seized blotter samples were also confirmed via high-performance liquid chromatography with ultraviolet detector. In a set of 41 blotters analyzed by EASI(+)-MS, 28 showed positive results for LSD, seven for 9,10-dihydro-LSD, and another six samples showed negative results for both LSD and 9,10-dihydro-LSD. The combination of thin layer chromatography with EASI-MS also demonstrated to be a relatively simple and powerful screening tool for forensic analysis of street drugs. 相似文献

Abstract: The gene encoding the dopamine D2 receptor (DRD2) has been suggested as a candidate gene for substance dependence. In this study, the possible association between Taq1A and Taq1B DRD2 polymorphisms and cannabinoid dependence was investigated. One hundred and twelve cannabinoid addicted and 130 healthy control subjects were included in this study. The Taq1A and Taq1B genotypes were determined in all subjects by polymerase chain reaction. For each polymorphism (A or B), the subjects were categorized into three groups according to their genotype, that is, the subjects with alleles A1/A1, A1/A2, A2/A2; B1/B1, B1/B2, and B2/B2. A significant association was found between Taq1A gene polymorphism and cannabinoid addicts compared to the control subjects. This finding suggests that polymorphism of the Taq1A, but not the Taq1B, may be associated with the susceptibility to cannabinoid dependence. Further clinical studies are required to be carried out for confirmation and evaluation of these findings. 相似文献

This paper reports the results of investigations carried out to elucidate the frequency and the structure of various forms of abnormalities of dentition among the children of the preschool and school age in the Republic of Armenia. These data may be of help for the forensic medical personality identification especially for the expertise of unrecognized corpses. Moreover, these data provide an indirect picture of the prevalence of abnormalities of dentition among the adult population of the country. Specifically they may sometimes be used to identify the ethnic and/or racial background of a person. 相似文献

Faded, or actively removed text on thermally printed paper samples may be enhanced and retrieved through the use of a simple iodine fuming procedure. The recovery of printed documentation evidence in this fashion is neither affected by prior fingerprint enhancement techniques (such as ninhydrin or DFO), nor by sample age. This method allows, for the first time, evidence to be obtained from completely faded thermal paper samples (receipts, for example) as well as allowing deliberately removed printed text (a consequence of solvent washing pre-treatment in latent fingerprint enhancement procedures) to be recovered. 相似文献

The objective of this study was to examine the association between education and domestic violence among women being offered an HIV test in urban and rural areas in Kenya. A sample selection of women who experienced physical (n = 4,308), sexual (n = 4,309), and emotional violence (n = 4,312) aged 15 to 49 allowed for the estimation of the association between education and domestic violence with further analysis stratified by urban and rural residence. The main outcome of interest was a three-factor (physical, sexual, and emotional) measure for violence with the main predictor being education. Nearly half of all domestic violence, physical (46%), sexual (45%), and emotional (45%) occurred among women aged 15 to 29. After adjusting for confounding variables, women who resided in urban areas and had a postprimary/vocational/secondary and college/university education were 26% (OR = 0.74, 95% CI: [0.64, 0.86]), p < .001 and 22% (OR = 0.78, 95% CI: [0.66, 0.92]), p < .01 less likely to have experienced physical violence compared to those who had a primary education respectively. This was 17% (OR = 0.83, 95% CI: [0.73, 0.94]), p < .01 and 17% (OR = 0.83, 95% CI: [0.72, 0.96]), p < .05 less likely among women who resided in rural areas. A surprising finding was that women residing in rural areas with less than a primary education were 35% less likely to have experienced sexual violence (OR = 0.65, 95% CI: [0.43, 0.99]), p < .01 compared to those who had a primary education. These findings suggest that physical, sexual, and emotional violence were prevalent in Kenya among married and formerly married women. This study indicates that more research is needed to understand factors for HIV/AIDS among Kenyan women who have specifically tested positive for HIV or identified as AIDS-positive and the implications for women's health. 相似文献

A fundamental question facing the regulatory and competition authorities is whether to delegate competition policy issues
of utilities to regulatory agencies or competition authorities. While, some countries prefer ‘light handed regulation’ by
competition authorities, others grant substantial power to independent regulatory agencies. Turkey followed the liberalization
wave in electricity with a regulatory reform in 2001. Recently, a slight shift of tide has appeared in previously liberalized
markets. Electricity markets are the forefront example of this change of course. A similar trend is apparent in Turkey as
well. Increasing pressures on prices and excess demand have created more reasons for active government involvement. As political
factors weigh in, economic considerations take a secondary place in electricity markets. In order to show the tension between
political and economic preferences, we use the Pareto and Kaldor-Hicks criteria of welfare economics metaphorically. This
paper discusses the scope of competition policy in the Turkish electricity industry. We focus on the issue of regulatory governance.
The absence of a well established institutional environment reduces the potential role of competition policy in the industry
and increase political meddling in all segments of the Turkish electricity market. By looking into changes in prices, market
power and new entry closely, we discuss the relative success of the regulatory reform in the electricity industry. We conclude
by emphasizing the consequences of a passive competition authority in establishing a competitive electricity market. 相似文献

This is a follow-up to a study demonstrating that rough-and-tumble play was related to physical aggression in the preschool
years. Fathers reported on the frequency of father-child rough-and-tumble play interactions, and the degree to which fathers
were dominant in the play dyad was observed and coded from play interactions. In this follow-up study, school-aged children’s
physically aggressive behaviors and emotion regulation abilities were assessed with questionnaires 5 years later. Higher frequencies
of father-child rough-and-tumble play in the preschool years were associated with more physical aggression and worse emotion
regulation 5 years later for children whose fathers were less dominant, over and above the effects of physical aggression
in the preschool years. Rough-and-tumble play was unrelated to these measures among children whose fathers were more dominant
during play. This study shows that early rough-and-tumble play continues to be related to children’s psychosocial adjustment
over time, and that the effect remains moderated by the quality of the father-child relationship during play. 相似文献

Abstract: This case review illustrates the important contributions of forensic archeological methods and forensic anthropological analysis to the identification of found skeletal remains. After reassociation of skeletal remains found in two locations, anthropological analysis provided the basis for a presumptive identification and a request for antemortem medical records. Partial DNA profiles were supportive but not conclusive and antemortem dental records were not available. Comparison of antemortem traumas, skeletal morphology, and surgical artifacts with antemortem radiographs and surgical records led to positive identification of an individual missing for almost a decade. 相似文献
