Monitor-based evaluation of pollutant load from urban stormwater runoff in Beijing.

As a major pollutant source to urban receiving waters, the non-point source pollution from urban runoff needs to be well studied and effectively controlled. Based on monitoring data from urban runoff pollutant sources, this article describes a systematic estimation of total pollutant loads from the urban areas of Beijing. A numerical model was developed to quantify main pollutant loads of urban runoff in Beijing. A sub-procedure is involved in this method, in which the flush process influences both the quantity and quality of stormwater runoff. A statistics-based method was applied in computing the annual pollutant load as an output of the runoff. The proportions of pollutant from point-source and non-point sources were compared. This provides a scientific basis for proper environmental input assessment of urban stormwater pollution to receiving waters, improvement of infrastructure performance, implementation of urban stormwater management, and utilization of stormwater.

网络环境下博物馆信息资源的采集策略

博物馆信息资源建设是博物馆信息化建设的重要组成部分。网络环境下的博物馆信息资源建设除了传统的藏品资源建设以外,还包括文献信息资源建设和网络信息资源建设等。针对不同的信息资源类型,采取不同的采集策略。时博物馆藏品档案信息,输入要完整、处理要规范、输出要主动,充分揭示藏品的文化内涵及实现其科技信息价值;对博物馆文献信息资源要拓宽进书渠道,实行采购方式多样化,重视数据库及灰色文献;充分挖掘网络信息资源,开展共建共享,全面提升文献信息保障能力。     

替代国制度对我国的影响及其应对策略

替代国制度是对被认定为是来自非市场经济国家的出口产品计算正常价值的一种方法。因此，确定一种产品是否存在倾销及倾销幅度的大小很大程度上取决于替代国的选择。在反倾销调查中导致我国出口企业屡屡被认定为存在倾销行为的重要原因之一就是替代国的选择不合理。面对替代国制度给我国带来的负面影响，如何有效应对成为我国政府和企业的当务之急。     

对现代项目管理新机制——PARTNERING(合作管理)的认识与探讨

本文从项目成功的标准谈起，介绍了同内外对工程项目管理方式的思考和实践，重点介绍了国外实施的一种现代项目管理新机制——PARTNERING（合作管理）。文章对PARTNERING的基本定义、核心内容、机制框架、工作流程进行了概括，并从交易成本经济学和绩效管理的角度分析了这种管理方式异于传统项目管理的理念、内涵。经过进一步分析，认为我国大型水利水电工程、南水北调工程的特性和建设管理适于应用PARTNERING管理方式。

Novel tiO2 nanocatalysts for wastewater purification: tapping energy from the sun.

Water treatment using TiO2 semiconductor as a durable heterogeneous photocatalyst has been the focus of environmentalists in recent years. Currently, we developed an inexpensive and highly efficient approach for synthesizing nitrogen-doped TiO2 with lower band-gap energy that can respond to visible light. Doping on the molecular scale led to an enhanced nitrogen concentration of up to 21.8%. Reflectance measurements showed the synthesized N-doped TiO2 nanoparticles are catalytically active with the absorbance that extends into the visible region up to 600 nm. The water purification potential of this new class of compound was evaluated by studying the photodegradation of Acid Orange 7 (AO7) and E. coli. Experiments were conducted to compare the photocatalytic activities of N-doped TiO2 nanocatalysts and commercially available Degussa P25 power under identical solar light exposure. N-doped TiO2 demonstrated superior photocatalytic activities in both chemical compound degradation and bactericidal reactions. The result of this study shows the potential of applying new generations of catalyst for wastewater purification and disinfection.
