车辆轮胎爆破在交通事故中较为常见,对爆胎痕迹进行检验和鉴定,弄清爆胎原因,在查明事故真相和责任认定中起着至关重要的作用。由于爆胎痕迹形成机理和原因复杂,检验鉴定的难度较大。通过对各类爆胎痕迹的形态特征及其差异的讨论,提出了交通事故中爆胎痕迹的检验要点。 相似文献

目的对裂解气相色谱-质谱法分析橡胶的裂解条件进行优化,研究利用橡胶特征裂解产物鉴别轮胎胎面胶。方法采用裂解气相色谱-质谱法,确定对NR、BR、SBR的裂解条件及其特征裂解产物,然后根据特征裂解产物及其相对含量并结合聚类分析,对38种轮胎胎面胶进行区分鉴别。结果确定了裂解温度590℃、裂解时间15s及三种橡胶的特征裂解产物;将38个轮胎胎面胶样品的主体成分归为4类,其中NR类5个、SBR类12个、NR/BR并用类5个、NR/SBR并用类16个,且能够对大部分并用类轮胎胎面胶进行鉴别。结论通过优化裂解条件,裂解产物重复性好,特征裂解产物明显,能够确定轮胎胎面胶的主体成分类别并能对大多数并用类轮胎胎面胶样品进行区分鉴别。 相似文献

This paper will attempt to situate the current discourse on 'crack pregnancies' within the context of a broader regulatory discourse.' It will argue that defining and locating state intervention solely within the confines of formal legal discourse not only privileges the criminal law, but (1) occludes recognition of the ways in which regulation and control are effected by administrative law and welfare policy and (2) fails to specify the role of the welfare state in the construction and reproduction of dominant cultural norms of womanhood and mothering. The paper draws on feminist literature and fieldwork-in-progress to suggest that many of these women are already subject to substantial mechanisms of social control and cultural reproduction. In concluding, it is suggested that the construction of this debate to date has served to deflect attention away from the fissures of gender, race and class that render these women's lives as publicly problematic. 相似文献

This Book of the Seton Hall Law Review presents the contributions to Follow-On Biologics: Implementation Challenges and Opportunities, a one-day roundtable event hosted by Seton Hall University School of Law in the fall of 2010. The roundtable fostered an international dialogue regarding the future of follow-on biologics in the United States resulting from the Patient Protection and Affordable Care Act of March 2010. THE BIOLOGIC PRICE COMPETITION AND INNOVATION ACT OF 2010. The March 23, 2010, enactment of the Patient Protection and Affordable Care Act (PPACA) and the companion Health Care and Education Affordability Reconciliation Act of 2010 ushered in landmark reform of the American health care system. Along with sweeping overhauls of the health care system generally, PPACA also provides a new regulatory challenge for the Food and Drug Administration (FDA). A subtitle within PPACA, the Biologics Price Competition and Innovation Act (BPCIA), bestows upon FDA broad authority to implement an abbreviated approval route to market for biological products (also known as biologics) that are "biosimilar" to an existing marketed product. The brief introduction will provide a basic comparison of biologics and conventional pharmaceutical drugs that will prove central to the FDA's development of this follow-on biologic pathway as well as specifically examine the content and scope of the BPCIA provisions and identify future challenges for the FDA. It will conclude by highlighting details of presentations during the roundtable held at the Seton Hall University School of Law and introduce the two resulting articles contained with this Book of the Seton Hall Law Review. 相似文献
