A Brief Review on Research on Post-disaster Stress and Some Directions for Future Implementation

The present paper proposes future possible directions for research in psychological intervention to raise the level of psychological preparedness for (natural) disaster. Based on past literature, the research trends in psychological study on post-disaster problems was reviewed to provide information and explanation on several socio-psychological phenomena arising from acute stress caused by disasters. Along with classical explanations on these phenomena, the authors theoretically explained the situation under disaster stress. The low level of psychological help-seeking in post-disaster society was also raised as a question and considered from psychological perspectives of help-seeking behaviour, and possible directions for future intervention were discussed. Keywords: post‐disaster, psychological preparation, resilienc

Treatment of algae bloom water using ·OH based on conventional drinking water process

我国水体的富营养化日益严重,水源地出现季节性藻类爆发现象,严重威胁饮用水安全。以厦门市莲坂水厂各工艺段出水为研究对象,采用大气压强电离放电产生羟; 基自由基(·OH),分别对水源水、混凝沉淀出水、砂滤出水进行处理,处理时间为4.5 s。当注入总氧化剂浓度为1.8 mg·; L~(-1)时,高藻浓度从25.3*10~4 cells · mL~(-1)降到800 cells ·; mL~(-1);对混凝沉淀出水注入总氧化剂0.6 mg· L~(-1)、砂滤出水注入0.2 mg·; L~(-1)时,藻细胞都未检出;·OH处理后CODMn、TOC及UV254均有明显降低,砂滤出水三卤甲烷小于8; mug·L~(-1);检测的各项指标均达到国家《生活饮用水卫生标准》(GB; 5479-2006)。因此,·OH可快速有效安全地杀灭高藻,为我国高藻水源地饮用水卫生安全保障提供技术支撑。Due to the increasing eutrophication in China, harmful algae blooms; often occur in water body periodically, which poses serious threats to; drinking water safety. Using a strong ionization discharge technology at; atmosphere pressure, ·OH was used to remove algae bloom. Other; conventional process such as coagulation, sedimentation and sand; filtration were applied respectively in the Lianban Water Plant in; Xiamen (China). The total reaction time required in the three water; processes was only 4.5 s. When the total reactive oxidant (TRO); concentration injected to algae bloom water was 1.8 mg·L~(-1), the algae; content was decreased by ·OH from 25.3*10~4 cells·mL~(-1) to 800; cells·mL~(-1). When the TRO that was injected into coagulation,; sedimentation and sand filtration water achieved 0.6 mg·L~(-1) and 0.2; mg·L~(-1), respectively, the algae contents were not detected (ND) in; treated effluents. At the same time, water quality in CODMn, TOC and; UV254 were decreased and the disinfection by-products(DBPs) such as,; trihalomethanes (THMs) concentration was lower than 8 mug·L~(-1) in; treated effluents. The treated effluent, resulting from this technology,; met the requirement of the National Drinking Water Standards (GB; 5479-2006). Therefore, ·OH was effective and safe to remove freshwater; algae without further treatment being required.国家科技支撑计划项目; 国家重大科研仪器研制项目; 科技部创新人才推进计划重点领域创新团

减阻沟槽边界层相干结构展向拓扑的分层可视化

采用高时间分辨率粒子图像测速系统(TR-PIV),分别对沟槽壁面及光滑壁面平板湍流边界层速度矢量场的时间序列进行了精细测量,并利用新象限分裂法及新条件采样与相位平均技术,在李山等人对数区结果的基础上,对光滑壁面和沟槽面湍流边界层近壁区及外区相干结构二维空间拓扑的形态进行了进一步地对比研究。结果表明:在近壁区和对数区内,与光滑壁面相比,不论喷射事件还是扫掠事件,减阻沟槽使得相干结构法向脉动强度降低最为明显,即相干结构在法向上的动量和能量交换减弱,削弱了其对湍流产生的贡献;而进入外区以后,减阻沟槽对法向脉动速度分量和展向涡量在喷射和扫掠过程中影响比内区要小,说明沟槽主要影响湍流边界层内区结构,且以..

o-アミノフェノールのギ酸エステル誘導体を用いたベンゾオキサゾール環構築法の開発

A novel synthesis of naphtoh［2,1-d］oxazol-5-ol, a model compound for the benzoxazole moiety of marine natural products nakijinols A and B, was achieved in five steps in 35% overall yield starting from commercially available 2-methoxy-1,4-naphthoquinone. The synthesis involved the following crucial steps: ⅰ reduction of an N-Boc-protected 2-amino-1,4-naphthoquione; ⅱ protection of the resulting 2-aminohydronaphthoquinone as its diformate form; ⅲ a simultaneous N-Boc-deprotection and cyclization of the resulting diformate to construct an oxazole ring
