A discrete nebulisation technique has been developed for the multi-element analysis of 100-μl solution droplets by inductively coupled plasma-optical emission spectrometry (ICP-OES). The technique increases analytical speed and uses very small solution volumes with only a slight degradation in detection limits when compared to continuous solution introduction.To evaluate its suitability in casework, small alloy fragments were produced by cutting with a hacksaw, sample division and filing. The analysis of fragments from two different brasses indicated that quantitative data could be obtained from fragments as small as 10 μg. The accurate determination of lead, a non-homogeneous constituent of leaded brasses, required sample sizes an order of magnitude greater. Analysis of an alloy of fine grain structure (copper-nickel) demonstrated that quantitative data could be obtained from samples weighing a few micrograms or less. 相似文献

This report describes a case of fatal retropleural hematoma complicating percutaneous insertion of a central vein catheter. The patient was a 55-year-old female undergoing surgery for severe rheumatic mitral valve disease. Factors responsible for this catastrophic incident are the anticoagulation of the patient, the edematous state of the soft tissues, and the multiple punctures of the wall of the jugular vein. 相似文献

In recent times, juvenile rehabilitation has been attacked both by liberals seeking to insert greater due process rights and protections into the juvenile justice system and by conservatives calling for more stringent handling of serious youthful offenders. The apparent pervasiveness of this attack raises the question, Is the philosophy of child saving dead? Data drawn from a survey conducted in Illinois suggest, however, that juvenile rehabilitation continues to receive support both from the public and from various groups associated with criminal justice practice and policy making. At the same time, there is also support for the notion that young criminals are responsible for their actions and are currently being treated too leniently by our courts. Finally, child saving is embraced most firmly by judges, lawyers, correctional administrators, and prison inmates and least strongly by legislators, prison guards, and the general public. 相似文献

This paper begins by assessing the current status of health care advertising and its potential for growth, arguing that this form of marketing is not just a passing fad among a few clinics and hospitals. It then describes the opposing schools of thought concerning the economics of advertising, and considers both theory and evidence on the effects of advertising on prices, profits, quality, utilization, and innovation. 相似文献

The authors describe the results obtained using the scanning electron microscope (SEM) to study drowned lungs and control lungs. Results are compared with a previous study carried out using laboratory animals. The results from both studies are analogous, in the absence of chronic pulmonary emphysema. The diagnosis of chronic pulmonary emphysema is simple with the SEM even when dealing with autoptic material obtained 24 to 48 h after death, but the diagnosis of drowning becomes difficult in lungs with chronic emphysema. 相似文献
