X80级管线钢管工程应用的几个问题

在对国内外大量文献和实际管道建设情况调研分析的基础上,结合国内X80级管线钢管的研究开发和产品试制结果,对我国管道界普遍关心的X80级管线钢管工程应用中的几个问题进行了论述.结果表明,采用高压输送及选用高钢级管材可以大量节约建设成本,是天然气管道发展的重要趋势.X80级已是国际上成熟的和标准的管线钢钢级,国际上在管道设计、生产、施工和运营等方面已有成熟经验.国内经过几年的研究开发首批试制的X80级管线钢管质量指标满足要求严格的X80级管线钢管应用工程标准要求,钢管实物质量与国外同类产品处于同一水平.国际上对输送普通天然气的X80级管道的断裂控制问题已经解决,根据对X80级管道启裂韧性和止裂韧性的分析研究及管道运行安全性的分析,用减薄壁厚的X80级替代X70级是安全的,也是可行的.未来X80级管线钢管在国际上的应用将会越来越广泛.实施X80级管线钢管工程应用是十分必要的.建议在未来大口径高压输气管线中优先选用X80级管线钢管.

Posttraumatic stress in children and adolescents exposed to family violence: I. Overview and issues.

Exposure to child physical abuse and parents' domestic violence can subject youth to pervasive traumatic stress and can lead to posttraumatic stress disorder (PTSD). This article presents evolving conceptualizations in the burgeoning field of trauma related to family violence exposure and describes how the often repeating and ongoing nature of family violence exposure can complicate a PTSD diagnosis. In addition, recent literature indicates that children exposed to family violence may experience problems in multiple domains of functioning and may meet criteria for multiple disorders in addition to PTSD. Considerations salient to the recognition of traumatic stress in this population and that inform assessment and treatment planning are presented.

Intensive filial therapy with child witnesses of domestic violence: A comparison with individual and sibling group play therapy.

The rationale for utilizing filial therapy as a treatment intervention with child witnesses of domestic violence while residing with their mothers in a shelter facility is explored and the effectiveness of an intensive 12-session filial therapy parent training group, conducted within 2-3 weeks, is described (n=11; aged 4-10 yrs). Results of analysis of covariance revealed that child witnesses in the experimental group significantly reduced behavior problems prevalent in child witnesses and significantly increased their self-concept as compared to child witnesses in the non-treatment comparison group. In addition, t-test results showed that mothers who facilitated treatment of the experimental group scored significantly higher after training on both their attitudes of acceptance and their empathic behavior. Comparative analysis revealed that intensive filial therapy as facilitated by the children's mothers was as effective in reducing behavior problems as was intensive individual play therapy and intensive sibling group play therapy as facilitated by professionally trained therapists.

论经济合理的生态用水量及其计算模型(Ⅱ)——应用

在“经济合理的生态用水量”概念及计算模型的基础上,以北京市为例,把该市的用水分为工业用水、农业用水、生活用水、第三产业用水、生态环境用水5个部分,分别计算各部分的用水效益,通过模型计算得出了符合北京市水资源实际情况的水资源分配数量。结果表明,在满足北京市经济用水和生活用水的基础上,经过模型计算调整后的用水效率从26.81元/m3提高到32.49元/m3,提高了20.42%。     

Municipal solid waste conversion to energy

In recent years it has been recognised by an increasing number of nations that there is considerable energy potential within MSW. As a result many countries have established R,D& D programmes to examine methods of exploiting this potential. The IEA's MSW Conversion Activity was set up in 1986 to provide an infrastructure for sharing information and co-ordinating work in this area internationally. This Activity was extended in 1989 and currently a total of 9 nations participate in it.

To cope with the wide scope of the area (encompassing both biological and thermal processing of MSW) the Activity was divided into three subgroups or Expert Working Groups (EWGs). Each of these dealt with a distinct area of expertise:

1. •Downstream effects of source separation and screening of MSW

2. •Sampling and analytical protocols

3. •Landfill gas

In addition to these groups a central secretariat based at Harwell (UK) has provided guidance, established and administered databases of contacts and produced a series of national reports.

This paper describes the achievements of the Activity and discusses work proposed for the future.
