The detection of a mixture of nine explosive compounds, including nitrate esters, nitroaromatics, and a nitramine in less than 140 sec is described. The new method employs a commercially available pulsed-discharge electron capture detector (PDECD) coupled with a microbore capillary gas chromatography (GC) column in a standard GC oven to achieve on-column detection limits between 5 and 72 fg for the nine explosives studied. The PDECD has the benefit that it uses a pulsed plasma to generate the standing electron current instead of a radioactive source. The fast separation time limits on-column degradation of the thermally labile compounds and decreases the peak widths, which results in larger peak intensities and a concomitant improvement in detection limits. The combination of short analysis time and low detection limits make this method a potential candidate for screening large numbers of samples that have been prepared using techniques such as liquid-liquid extraction or solid-phase microextraction. 相似文献

In December 2002, approximately 250 lbs. of ground beef was adulterated with nicotine sulfate by a supermarket employee and subsequently sold to the public. Soon afterward, reports of illness associated with ground beef purchased at a single store were identified. Authorities suspected the ground beef was tainted with Black Leaf 40, a banned pesticide containing approximately 40% nicotine as nicotine sulfate. Ground beef submitted to our laboratory was analyzed in concert by high performance liquid chromatography-ultraviolet detection (HPLC-UV), gas chromatography-mass spectrometry (GC-MS), and high performance anion exchange chromatography with suppressed conductivity detection. GC-MS was used to identify the samples that contained nicotine. The nicotine was confirmed and quantitated by HPLC-UV. The sulfate was identified and quantitated by high performance anion exchange chromatography with suppressed conductivity detection. Our analysis revealed that the raw tainted beef contained about 350 mg/kg nicotine free base, a potentially lethal dose of nicotine per serving for an adult. Additionally, we found elevated sulfate levels in the samples that tested positive for nicotine, providing evidence that nicotine sulfate was the probable adulterant. 相似文献

We investigated whether people need to believe in a just world in part because such a belief helps people to work toward long-term
goals and to do so in such a way that they are deserved. We assessed participants' long-term goal focus and also their commitment
to deserving their outcomes (via a psychopathy scale). In a second session, participants were then exposed to a victim whose
situation did or did not contradict a belief in a just world. When the victim's situation contradicted a belief in a just
world, the greater the participants' tendency to focus on long-term outcomes, the more they blamed the victim for her misfortune;
but this relation only occurred for participants with a strong commitment to deserving their outcomes (i.e., those low in
psychopathy). The results are consistent with our argument that, given the function of the belief in a just world proposed
in this article, people would have a greater need to preserve the belief (e.g., by blaming victims of injustice) the greater
their investment in long-term and deserved outcomes. 相似文献

This paper examines individuals who were victims of domestic violence in Illinois between 1990 and 1995, comparing the traits and service needs of those who received assistance in an urban county over the 5-year period with those who were served by domestic violence programs in rural areas. Analysis focuses on the demographic characteristics of clients in each region, their relationship to the abuser, type of abuse, referral source, and need for both concrete and supportive services. In addition to looking at variations by region, analysis examines differences between African American and White clients within and across geographic areas so that the interaction of race and location is highlighted. Results indicate that apart from demographic differences related to race, there is little difference in the circumstances of abuse when victims in the urban region are compared to rural victims of violence. However, those in rural environments regardless of race, have more service needs. Differences in service needs also exist in relation to race, and for some services, both race and location are important. The implications of these findings for policy, practice, and future research are examined. 相似文献

We present a case of peritonitis and death due to the misplacement of a laparoscopic adjustable band inserted through, instead of around, the stomach. This represents the first case in the published literature where a LAP-BAND perforated the stomach, followed by peritonitis and death. The morbidly obese female patient with a history of hypertension and arthritis was 47 years old, 5 feet 6 inches tall, weighed 361 pounds, and had a body mass index of 58.3. She underwent a 2-hour, elective, LAP-band insertion operation to achieve weight loss; 27 hours after band insertion, following the conduction of all FDA-mandated Lap-Band postoperative protocol (including a radiologic Gastrogrografin swallow), the patient was discharged with "no evidence of esophageal stasis or obstruction." She remained out of hospital care and in her residence until she called for and was taken by an ambulance to an alternate, local hospital (57 hours after band insertion), when gastric perforation was confirmed via x-ray and CT scans. No open surgery was attempted to repair the damage, and cardiac arrest ensued 7 hours after admission to the second hospital. The patient was pronounced dead 64 hours after LAP-band insertion. This unique case is significant, given that there were no deaths of this kind reported in The LAP-BAND(R) Adjustable Gastric Banding System Summary of Safety and Effectiveness Data by the United States Center for Devices and Radiologic Health, of the Food and Drug Administration, or in searches of the published literature. 相似文献

This article suggests a model for objectively evaluating "nontraditional" religious practices in child custody and visitation rights cases. The model draws a distinction between religious beliefs and religiously motivated behavior. This distinction assists the evaluator in approaching the family in an unbiased, objective, and respectful manner. Emphasis is placed on considering the religiously motivated behavior in a constitutionally sensitive procedure that simultaneously protects the fundamental rights of parents and children and the children's best interests. 相似文献
