基于MIKE 21的长江江山制药排污口水环境影响分析——以江山制药公司污水处理站为例

为分析长江沿岸入河排污口设置对水环境的影响,采用MIKE 21建立了长江马鞍山-高桥段二维非稳态水量水质模型,并以江山制药公司污水处理站为例,对其排污口迁址改建前后的水环境影响进行模拟.结果 表明,较于原排污口排放,拟设排污口在执行新排放标准情况下,对九圩港入江断面水质有改善作用,COD、NH3-N、TP的改善率分别为...

高压直流输电换流阀冷却系统泄漏保护分析

提出了一种高压晶闸管换流阀冷却系统泄漏保护方法,当水冷却系统在一定时间内泄漏量超过换流阀要求的泄漏流量时泄漏保护能正确动作,同时避免由于冷却介质的热胀冷缩而引起误判断,对国内新建直流工程有指导意义。     

欧盟民防机制经验及其借鉴

突发公共事件产生的原因往往是多方面的,发生过程也不是孤立的,其处置需要多个部门和区域的配合协调.为了应对跨区域灾难,我国政府付出了诸多努力以提高本国应急管理能力.然而,我国横向的管理碎片化问题仍然存在,大大影响了我国的应急管理效果.欧盟作为一个区域一体化组织,其民防机制涵盖多方参与者,跨国、跨区域协调功能得到国际社会的普遍认可.研究欧盟如何成功协调各国在应急管理行动中的关系将为我国有效应对跨区域灾难带来启示.     

呼吸器标准中的泄漏率与实验室呼吸防护水平

结合国内外呼吸器最新标准中有关泄漏率与实验室呼吸防护水平的测试条件和方法,从基本概念和评价方法入手对比剖析了不同标准之间内容的差异.文中涉及的国内外标准主要有美国职业安全与健康研究所指定的系列化生放核呼吸器标准、欧洲EN 13274 - 1:2001、日本JIST8159:2006、中国GB 2626 - 2006和GB 2890 - 2009以及ISO/DIN 16900-1.2草案.通过对比分析不同标准之间在评价方法中采用的气溶胶种类、受试者人数、模拟动作种类及持续时间、采样方法、测试结果评价方法等具体内容,指出了我国呼吸器标准中泄漏率测试方法及相关标准发展中应注意的问题.     

From concept to practice: the long road to operationalising protection

For the past two decades, humanitarian actors have been grappling increasingly with the complex issue of protecting civilians. The definition of protection adopted by humanitarians is considered to be too broad to provide effective operational direction. This paper aims to contribute to recent initiatives to operationalise protection. Teasing out a broad typology of humanitarian protection through an examination of the scope, objectives, and strategies of a range of humanitarian actors, it suggests, would result in better identification of gaps and the channelling of efforts to support a system‐wide protection response. Emphasising recent calls for collective analysis as a means of eventuating protection, the paper also draws attention to the contested understanding that may arise concerning solutions to protection crises. Closely entwined with politics, protection defies neat technical solutions. The paper concludes that deepening knowledge of how communities conceive their own interests may provide the basis for a collective protection response.     

Flooding and schools: experiences in Hull in 2007

Hull, a city in the East Riding of Yorkshire, United Kingdom, suffered severe flooding in June 2007, affecting some 8,600 households and most schools. Despite the potential for damage in such disasters, no studies of the effects of floods on teachers and schools in the UK appear to have been published previously. This study analysed the impacts of the floods on teachers in Hull in two stages: first through correspondence with Hull City Council and a mailed questionnaire to 91 head teachers of primary, secondary, and special schools; and second, through in‐depth interviews with head teachers from six flooded schools, representing different degrees of flood experience, and a questionnaire completed by eight teachers from the same schools. The findings reveal the importance and the complexity of the role of the school in the wider community in a time of crisis. The study highlights issues concerning preparedness for floods, support for schools, and flood protection for schools.
