Study of TATP: stability of TATP solutions

Stability of raw TATP (3,3,6,6,9,9-hexamethyl-1,2,4,5,7,8-hexoxonane) samples in solutions of common solvents was studied to highlight problems faced by forensic labs in identification and analysis of organic peroxide samples. The TATP samples were prepared by reaction of acetone and hydrogen peroxide (30%) with the aid of following catalysts: hydrochloric, sulfuric, nitric, perchloric and methanesulfonic acid. Acetone, acetonitrile, methanol and acetonitrile/water solutions of TATP samples were prepared and stored at 50°C. Various degrees of stability were observed for particular combination of catalyst and solvent ranging from totally unstable (catalyst-H(2)SO(4)/any solvent) to very stable (catalyst-HCl/solvent acetonitrile). Purification of crude TATP by re-crystallization results in product stable in all investigated solvents. Stability of solution prepared from re-crystallized DADP (3,3,6,6-tetramethyl-1,2,4,5-tetroxane) was found to be on the same level as the stability of solution of re-crystallized TATP.     

Posttraumatic stress disorder in a World War II concentration camp survivor caused by the attack of two German shepherd dogs: case report and review of the literature

A 79-year-old woman suffered from acute posttraumatic stress disorder (PTSD) and a loco typico, non-displaced fracture of her right distal radius due to an incident involving the assault of two unleashed owned dogs, which suddenly ran into her and aggressively jumped on her chest and knocked her down to the ground. Recovery for her damage claim concerning pain and disability due to her right forearm fracture caused by the incident, was not the issue in the litigation concerned. However, the issue of delayed impact of her previous Holocaust experience placed a significant challenge on M.N., as a plaintiff, in establishing a causal link between the posttraumatic stress disorder concerned and the alleged harmful action of the defendants, the owners of the two dogs. The case reported here proved interesting and instructive not only in the sense of addressing main issues relevant to litigation for psychological damage related to reactivated PTSD and delayed PTSD, but also in the sense of pointing at the clinical relevance of dog assaults on humans which, even without dog bite injuries, may result in a severe traumatization and eventual civil lawsuit.     

The Territorial Scope of Employment Legislation and Choice of Law

Traditionally, the determination of the territorial scope of the statutory rights conferred by employment legislation forming part of English law has been regarded as an issue entirely disconnected from the choice‐of‐law process. Indeed, this view formed the basis of the key decision addressing the problem of territoriality, Lawson v Serco, decided by the House of Lords in 2006. After presenting the current state of the law with regard to the territorial scope of employment legislation, this article takes a critical look at Lawson v Serco. It is argued that the ‘European’ choice‐of‐law rules must have a greater importance for determining the territorial scope of employment legislation and, consequently, that the approach pursued in Lawson v Serco is no longer correct, if it ever was, and should not be followed in the future.

越南革新开放以来电力业的发展及相关制度的建立完善

自越共“六大”提出“革新”战略以来,越南的经济社会步入了一个前所未有的快速发展时期①。对电力的需求也El益扩大,但越南电力业的发展相对滞后,电力业的发展成为制约越南经济社会发展的重要因素。21世纪以来,越南把电力业的发展放到了战略性的高度,制定了《电力法》,并把电力发展作为战略性领域纳入越南中长期经济社会发展规划,取得了较大成就,为越南经济社会的发展提供了保障。多年来,中国电力企业积极进入越南电力市场进行投资和贸易。研究越南近年来电力业的发展及其制度,有利于我国企业进一步拓展越南电力市场,促进我国对外投资和贸易。     

牙刷刷毛黏附口腔黏膜脱落细胞DNA的检验方法

目的 探索牙刷刷毛黏附口腔黏膜脱落细胞DNA提取有效方法.方法 采用牙刷刷毛拔出法和直接涮洗法收集口腔黏膜脱落细胞,分别用Chelex-100法和DNA IQ试剂盒提取DNA进行PCR扩增及STR分型.结果 牙刷刷毛拔下后收集口腔黏膜脱落细胞检测STR 9个以上基因座成功率明显高于直接涮洗法,差异具统计学意义(P<0.05).Chelex-100法和DNA IQ试剂盒提取法之间差异无统计学意义(P>0.05).结论 牙刷刷毛拔出法较直接涮洗法收集口腔黏膜脱落细胞更有效.     

马克思人的本质观及其方法论启示

马克思人的本质观克服了西方传统哲学中对人的本质作抽象孤立理解的缺陷,充分显现了唯物史观的精神实质。马克思人的本质观立足于现实的人,以人的感性实践为逻辑起点,使人的一切社会关系成为人的本质之形式规定,并强调人的需要是驱使人的本质变化发展的动力。马克思人的本质观为我们进一步理解人提供了重要的方法论启示:在历史性的维度上人是共性和个性的具体统一,在理想性的维度上人是受动性和能动性的动态统一,在现实性的维度上人是自然性和社会性的完整统一。     

未成年人犯罪及其防治实证研究——以浙江省未成年人犯罪及其防治为范例的分析

未成年人犯罪数量不断上升,覆盖的罪名持续增多,涉足的领域逐渐扩大,社会危害性日趋严重,未成年人犯罪防治面临十分严峻的形势。应通过完善保障未成年人权益立法、加强未成年人犯罪综合治理、健全未成年人犯罪司法保护工作机制等多种途径有效防范未成年人犯罪。     

“正义原则”的人学价值透视

罗尔斯在其《正义论》中提出平等自由原则和差别原则,这两个正义原则具有"以人为本"的人学价值:它为人的德性发展创造了条件,为实现人的价值创造了良好的环境,肯定了人的自尊、自爱和自信,关切人的幸福,彰显人的主体性,使人的自主性、能动性和创造性得以发挥,主张人们相互把对方作为自在的目的而非手段来对待.然而,罗氏的幸福观只顾及到人们眼前的个人生活,没有从人类社会的未来的视角去挖掘,他看到了人的目的价值,却忽视了人的实践活动,没有看到人的手段价值.正义原则的人学价值对我们构建和谐社会具有重要的借鉴意义.
