Thermal hazard assessment of TKX-50-based melt-cast explosive

In the present study, thermal hazards of TNT and DNAN used as the molten binder in TKX-50-based melt-cast explosives were comparatively studied through accelerating rate calorimeter (ARC) and Cook-off experiments. Two kinds of ARC operation modes were performed to investigate the thermal safety performance under adiabatic conditions (HWS mode) and constant heating (CHR mode). The obtained results demonstrated that at both heating modes, DNAN/TKX-50 outperformed TNT/TKX-50 from the thermal safety point of view. However, the sensitivity to heat of the samples was reverse because of the different heating modes. In addition, the results of thermal hazard assessment obtained from the cook-off experiment complied with ARC analysis which indicated the molten binder TNT replaced by DNAN would reduce the hazard of the TKX-50 melt cast explosive. Furthermore, the results of cook-off experiments also showed that DNAN/TKX-50 outperformed TNT/TKX-50 from the aspect of thermal stability, which was consistent with the result of CHR mode because of the similar heating process.     

Terrorism,crime and public spending: Panel VAR evidence from europe

Within a panel VAR framework and utilizing generalized impulse response and forecast error variance decomposition analysis, we explore the dynamic effects of terrorism and crime on public order and safety spending across European countries during the period 1994–2006. Our findings show that a ‘shock’ in terrorism and/or in crime, significantly increases the subsequent trajectory of public order and safety spending. As a by-product, we find that public spending is ineffective in reducing observed crime or terrorism.

影响油罐电位的输油参数分析

目前,油库、储运公司改扩建工程较多,不可避免对工艺流程进行调整,依据液体静电产生原理,应用高斯定理和欧姆定律等理论,分析油罐注油过程中油面电位以及时间与管径、流速等各参数之间的关系,针对管径不变流速变化的情况,进行实验分析,在不对管路进行整改,仅对泵进行重新设计优选时,对如何控制罐内电位的安全,提出参考方案,对油库改扩建工程有一定的指导意义。     

Disaster management in case of CBRNe events: an innovative methodology to improve the safety knowledge of advisors and first responders

Nowadays, Chemical-Biological-Radiological-Nuclear-explosive (CBRNe) risks are one of the world's main safety concerns. The radiological disasters of Fukushima and Chernobyl, the chemical events of Seveso or the release of Sarin in the Tokyo Subway, the biological emergencies such as the H1N1 flu or the recent Ebola outbreak, and recent news about the availability of non-conventional weapons acquired by fundamentalist organisations represent evidence of potential future threats. CBRNe risks are a real and global threat. The University of Rome, Tor Vergata, in collaboration with the most important Italian and international bodies working in the field of CBRNe safety and security, and supported by the North Atlantic Treaty Organisation and the Organisation for the Prohibition of Chemical Weapons, organises International Masters Courses on the Protection against CBRNe events. Within this framework, a Table-Top Exercise was planned, in collaboration with the Italian Ministry of Interior and Ministry of Defence. The scenario, the logistic organisation, on-going adjustments during the exercise and the outcomes are presented here and analysed.     

基于认知模型的人为差错分类方法

为了保证人为差错分类的全面性和一致性,在详细分析现有人为差错分类方法的基础上,提出了一种新的人为差错分类框架.该框架以"执行差错,忽略"为起点进行细化,得到五种基本的人为差错类别.以此作为人为差错原语,结合认知模型,分析了不同认知阶段可能出现的人为差错模式.实例证明,在这种分类方法指导下来分析人为差错,对提高人为差错分类结果的全面性和一致性有着重要意义.
