纵火现场中汽油、煤油和柴油残留物的ATD/GC/MS法检测 总被引:1,自引:0,他引:1
目的为火场中汽油、煤油和柴油残留物的检测建立一种简便、高灵敏度的ATD/GC/MS检验方法。方法采用Tenax TA吸附管吸附富集检材中的汽油、煤油和柴油成分。然后用美国PE公司的ATD/GC/MS仪器进行全自动的解吸和分析检测。结果检材中汽油、煤油和柴油的检测极限分别达0.05、0.2、0.2pL/mL。结论该方法具解吸和分析检测过程自动化。操作简便快捷,检测灵敏度高。杂质干扰少等特点,可用于实际火场皆汽油、煤油和柴油残留物的检测。 相似文献

Abstract This paper addresses the burgeoning Human Immunodeficiency Virus (HIV) crisis in the black community in the United States, particularly black women. A cognitive-behavioral skills-building HIV prevention intervention tailored to the realities of blacks in South Africa is presented as a model that may be modified and adapted for HIV prevention among blacks in the United States. This model of HIV prevention must view blacks as a heterogeneous group that includes African immigrants, and cognitive-behavioral skills-building HIV prevention interventions tailored to the realities of black women are needed for the prevention of heterosexually transmitted HIV infection. The implementation of HIV interventions within accessible sexually transmitted diseases (STD) testing and treatment programs will provide the combined clinical-behavioral approach that is missing in HIV prevention interventions among blacks in the United States. 相似文献

作为一种司法改革举措,民间习俗在一些法院中得到运用,民间习俗对国家司法的影响力也就成为需要法理论证的问题。在中国语境中反思哈特与德沃金关于此问题的观点,他们的思想仍有许多启发作用。哈特通过承认规则塑造了习俗的有效性,而德沃金则通过权利原则将习俗引入国家司法。尽管哈特与德沃金意见有所分歧,但他们从不同视角提供了习俗进入司法的实践方法。 相似文献

The primary goals of this study were to test the long‐term stability thesis of Gottfredson and Hirschi's (1990) general theory of crime and to examine the relationship between self‐control and social control over time. The data come from a field experiment where the “treatment” consisted of an intentional effort to improve the childrearing behaviors of a sample of caregivers whose children were at high risk of criminal behavior. Caregivers in the control condition were given no such training. The intervention occurred when all subjects were in the first grade (mean age: 6.2 years old), and we have measurements on self‐control and the social control/bond for each subject from grades 6 to 11 (mean ages: 12 to 17 years old). Both a hierarchical linear model and a second‐order latent growth model identified meaningful differences in the growth pattern of self‐control among individuals in the pooled sample and a difference in the growth parameters for self‐control and the social control/bond over time between the treatment and control groups. Both findings are inconsistent with Gottfredson and Hirschi's stability of self‐control hypothesis. The same patterns persisted when different analytic techniques and model specifications were applied, which suggests that the results are not an artifact of measurement error, model specification, or statistical methods. Structural equation modeling using the panel design of the data was better able to disentangle the long‐term relationship between self‐ and social control—a relationship that was found to be more dynamic than previously hypothesized. 相似文献

Analytical Challenge in Postmortem Toxicology Applied to a Human Body Found into a Lake after Three Years Immersion 下载免费PDF全文

The body of a 30‐year‐old woman was found in Como lake at a depth of about 120 meters in her own car after 3 years of immersion. The aim of this study was to evaluate psychoactive drugs as well as alcohol biomarkers in biological matrices. The following analyses were initially performed: GC‐MS systematic toxicological analysis on biological fluids and tissues; GC‐MS analysis of drugs of abuse on pubic hair; direct ethanol metabolite determination in pubic hair by LC‐MS/MS. After 7 years, the samples, that had been stored at ?20°C, were re‐analyzed and submitted to an LC‐MS/MS targeted screening method, using multiple reaction monitoring mode. These analyses detected citalopram (150–3000 ng/mL), desmethylcitalopram (50–2300 ng/mL), clotiapine (20–65 ng/mL), and ethyl glucuronide (97 pg/mg). The methods showed an acceptable reproducibility, and the concentrations of citalopram and desmethylcitalopram calculated through the two analytical techniques did not significantly differ in biological fluids. 相似文献

我国著作权法引入惩罚性赔偿机制具有理论正当性和现实必要性。为避免出现“双刃剑”效应,我国在合理建构著作权惩罚性赔偿制度时,需注意两方面问题:其一,应当结合我国现阶段著作权交易的实际情况,审慎界定惩罚性赔偿的适用条件;其二,应当妥善处理好惩罚性赔偿与法定赔偿的关系,避免对侵权行为人施加重复性惩罚。 相似文献

This article constitutes a pointed theoretical intervention in the debate opposing Richards and Smith to Flinders on the question of citizen disengagement. Its main contention is that Richards and Smith offer a straw‐man argument against Flinders by identifying him with positions he does not hold. It thus shows that Richards and Smith falsely identify Flinders with the following positions: (a) there is no need for a major overhaul in the UK's existing democratic and governance arrangements; (b) the problem of citizen disengagement is caused by the public's insatiable demand for democratic participation; and (c) the problem with British politics is that there is too much democracy and accountability. Finally, the article closes by identifying points of genuine tension between the Richards/Smith position and that defended by Flinders. 相似文献

Along the Texas border with Mexico, more than 400,000 people live in over 2,000 informal self-help settlements known as colonias. These exceedingly low-income, largely Latino settlements have historically suffered from severe health risks, poor infrastructure and housing conditions, and physical and social isolation. Researchers and policymakers have focused extensively on what I call “first-generation policy priorities.” This has primarily entailed efforts to regularize title and infrastructure, support self-help home improvement for colonia homeowners, and prevent the growth of new informal settlements along the border region. I provide a comprehensive review of existing research on colonias to document the myriad ways in which housing and infrastructure conditions and titling practices have changed since these settlements first proliferated throughout the border region in the second half of the 20th century. These changes necessitate a rethinking of the policy priorities for colonias and informal settlements throughout the state. In particular, I argue that colonias must be recast to recognize the significant improvements that have taken place but also the long-term and sometimes severe problems that persist. These “second-generation policy priorities” include the development of sustainable forms of governance, regulation, and finance to address ongoing infrastructure investment needs in colonias; supporting access to and upkeep of safe and affordable renter- and owner-occupied housing through both self-help and contractor-led projects; ensuring long-term title clarity; and promoting community organizing in new and aging settlements. 相似文献
