This study aimed to expand the scope of previous research by assessing the effectiveness of soot-removal techniques on glass from petrol-bomb debris using methods of 1% and 2% sodium hydroxide (NaOH) solutions, ultrasonic bath and vacuum suction. Of particular interest were the 1% and 2% NaOH solutions applied to the soot-covered surfaces. Petrol bombs containing petrol or a 50:50 mix of petrol and motor oil were exploded and the debris was collected for analysis. Favourable results were found to varying degrees using each of the soot-removal methods with the 1% and 2% NaOH wash solutions, being the most useful. The 2% NaOH solution also proved successful as a soak to loosen and remove heavy contamination of soot and accelerants without damaging the finger mark beneath. This study also found that recovery of finger marks in blood from beneath soot using the 2% NaOH solution was possible. Finger marks were also applied to glass bottles with plastic adhesive labels, and providing the fire damage is not too great marks were also retrievable. Results from this study lead to the conclusion that the NaOH wash solution is ideally suited for soot removal to reveal latent and blood-contaminated marks both within the laboratory and at crime scenes. 相似文献

Acute myoglobinuria as a fatal complication of heroin addiction 总被引:3,自引:0,他引:3
Y F Chan P K Wong T C Chow 《The American journal of forensic medicine and pathology》1990,11(2):160-164
A fatal case of myoglobinuria complicating heroin addiction is described. Clinically the patient had no overt symptoms of rhabdomyolysis. Pathologists should be alerted to this rare complication in heroin addicts who die of no apparent cause. The antimyoglobin immunoperoxidase technique is useful in confirming the diagnosis. 相似文献

Conclusion In the event of death, society has in place a wide range of rituals and supports designed to help mourners deal with their grief. It may be that assigning blame and seeking legal recourse has become a significant ritual for those who have sustained other types of losses and, in some situations, loss through death as well. However, unlike societal death rituals, which guide the mourners, no guidelines exist to help negotiators address the impact of grief on their clients. Thus, in this article, insights gleaned from studies of grief, loss, and separation have been examined in an effort to develop an awareness of the impact of grief reactions on the parties to negotiation.Grief reactions—ranging from denial, bargaining, anger, depression, and guilt to acceptance—serve a useful purpose for those who have sustained grievous losses. Consequently, a better understanding of grief factors may be advantageous to negotiators and, more importantly, to their clients. Such considerations may help challenge perceptions of other parties that may otherwise be prejudicial to one's client (as in the Lindy Chamberlain case) and assist negotiators in trying to anticipate, and thus protect their clients from, grief-related reactions of other parties. In the large number of cases where negotiation and settlement discussions are not only critical but also decisive, grief theory may provide negotiators with better insight into client, and other party, interests and may help them to formulate advice and intervention strategies that take the impact of various grief reactions into account.

This paper reports results of a study based on a nationally representative sample of U.S. youth (N = 11,549) that asked two questions: (1) How does family structure affect the likelihood of adolescent death beyond that of race/ethnicity, sex, socioeconomic status, personal behavior, and other structural factors and (2) under what conditions might appeals for social justice be warranted for relative mortality statuses and for absolute gains in mortality? The study found that marital instability increases the likelihood of dying when controlling for a variety of other factors including class, race/ethnicity, sex, and unemployment rate in area of residence. The author argues that this finding lends support to social justice arguments to redistribute resources in such a way as to ensure the likelihood of absolute gains in mortality. The study also found, however, that race/ethnicity/sex also accounted for the likelihood of dying independently of family structure when controlling for socioeconomic and other factors. The author argues that this finding lends support to social justice arguments to redistribute resources on the basis of relative mortality statuses. 相似文献
