The case of a 69‐year‐old man, equipped with an ICD and suffering from several chronic cardiac diseases, who died in a car accident, was presented. We analyzed electrogram records from the ICD explanted from the body during the autopsy, which showed that the driver had suffered from malignant ventricular arrhythmia—ventricular fibrillation (VF). A thorough analysis of the details of the accident, as well as the timing of VF and the rhythm observed after the discharge of the ICD showed that the direct cause of the accident was the episode of arrhythmia resulting in a loss of consciousness. Therefore, the presented case illustrates the usefulness of postmortem analysis of electrogram records from ICDs in the reconstruction of road traffic accidents. In such cases, if the victims are implanted with ICDs, it should be a routine procedure performed by forensic pathologists.  相似文献

Evidence materials in a presumed suicide case were studied by a firearm examiner and a forensic chemist. The victim's body with double gunshot wounding in his forehead, a machine gun in the sustained fire mode with a silencer, and four cartridge cases were found. Examinations of the evidence, the case file studies, and experiments dedicated to the case were carried out. Relationships between the placement of cartridge cases and the gun were established using a fast camera. The distributions of gunshot residues on the evidence materials and within the comparative gunshot patterns were studied by means of optical and electron microscopy, X‐ray microanalysis, and infrared spectroscopy. The shooting distance was assessed to be 30 cm or more, whereas the greatest distance that could have been achieved by the victim himself was about 11–13 cm. The obtained results supported the version of homicide rather than suicide.  相似文献

This article shows that templates are not only crucial for the ways in which journalists construct or structure the media discourse but also for how they perceive themselves and others in the process of journalistic practice. A Critical Discourse Analysis of interviews with Polish journalists on their practices related to reporting migration – a topic largely discarded and ignored by the Polish media – shows that the construction of practice in the journalistic field constantly negotiates the contradiction between “knowing-it-all”, a key element of the template of journalistic habitus/identity, and the frequent lack of experience or limited knowledge of practice and of journalistic work. The analysis reveals that, while often using a discursive strategy of pre-legitimation, journalists enact templates that blur the boundaries between discourses about experiences of journalistic work and imaginaries or scenarios of actions they would only potentially undertake. Journalistic discourses of practice thereby become increasingly displaced, that is, they run along similar templates of discourse of/about quasi-universalised ethics and values of journalism almost irrespective of media organisations of the informants. By the same token, it is emphasised that, rather than being limited by the ideologies and powers of media organisations, agency seems to be often self-constrained by journalists in their self-entrapment in values, templates and imaginaries of journalism.  相似文献

Simple, reliable, sensitive, and accurate spectrofluorimetric and spectrophotometric methods were proposed for the determination of two selected analgesic drugs, namely tramadol and morphine, in pharmaceuticals and biological fluids. The proposed methods were based on the oxidation of the studied drugs by Cerium (Ce)IV in an acidic medium. The spectrofluorimetric method is based on measuring the relative fluorescence intensity of Ce(III) arising from Ce(IV) at 350 nm with an excitation wavelength at 250 nm. The spectrophotometric method involves on addition of a known excess of Ce(IV) to the studied drugs in an acid medium, followed by the determination of residual Ce(IV) by reacting with a fixed amount of methyl orange and measuring the absorbance at 510 nm. Different variables affecting the reaction conditions, such as the concentrations of Ce(IV), type and concentration of the acid medium, reaction time, temperature, and the diluting solvents, were carefully studied and optimized.  相似文献

After 17 years of civil strife in Lebanon, an Office of Minister of State for Administrative Reform (OMSAR) was established in 1993 to plan for short‐term rehabilitation and long‐term institutional development within the public sector. Since external technical assistance to public administration was delivered through OMSAR, its role as a host agency for international aid donors' efforts in reform policy‐making and implementation is critical. The article discusses OMSAR's approach to channelling foreign aid for administrative development in post‐war Lebanon. Lessons from the Lebanese experience in post‐war institutional development may interest countries emerging from conflicts and trying to rebuild administrative infrastructure.
