芝加哥崛起的基石：“1909年计划”

“1909年计划”亦称“芝加哥计划”,是芝加哥在20世纪初为消除社会弊病而制订的一项综合规划方案,推行了长达半个世纪。本文评析了该方案产生的时代背景、具体内容及实施结果,揭示了它对芝加哥及美国社会发展产生的深远影响,并在此基础上提出了几点经验教训。

2001年绵阳科学城地区辐射环境监测与质量评价

2001年绵阳科学城地区主要环境介质(大气、河水、土壤和沉降等)中放射性水平与科学城开工前天然本底辐射没有显著性差别。通过对每个核设施烟囱流出物的测量与估算,获得了烟囱排放源项数据。利用该地区的大气扩散模式和多烟囱排放的剂量叠加原理,在评价坐标系中计算了叠加剂量分布。辐射环境质量评价表明80km范围内最大个人有效剂量是公众剂量限值的十万分之四,健康危害是危害约束值的千万分之二。表明环境影响是微弱的,是人们可以接受的。     

西安市生活水源水体中天然铀含量调查

对西安市生活饮用水源黑河与灞河水体中天然放射性元素铀含量进行了调查。共采集黑河水样12个,采集灞河水样42个,分析结果表明,两者水体中铀浓度属正常本底水平,但灞河水体中铀含量与十年前报道的调查结果比较,有明显增高趋势,应引起有关方面的关注。     

黑龙江黑河孟德河金矿床控矿因素及找矿标志

孟德河金矿床赋存于多宝山—大新屯北东向成矿带的新元古界北宽河组变质地层中,地层平均Au丰度值为0.17×10-6,为区内金矿床的主要矿源层。矿体呈陡倾斜似层状产于北宽河地层内,普遍发育的岩浆岩为金矿床的形成提供了部分物源和热动力,北东向韧性剪带及张性断裂构造为矿液的运移、聚集成矿提供了良好的场所。在分析矿床地质特征的基础上,探讨了控矿因素,归纳总结了找矿标志,并初步探讨了孟德河金矿床的成因。矿体严格受韧性变形带控制,矿体产于韧性变形带的强烈变形部位,矿床成因类型应为韧性剪切带型。     

山东栖霞马家窑金矿床地质特征及成因探讨

马家窑金矿床位于栖霞—蓬莱成矿带上,矿体赋存在新太古代的变质侵入岩中,控矿构造为马家窑—上庄头断裂的次一级断裂构造。结合马家窑金矿床地质特征,碳酸盐岩的碳、氧同位素组成特征显示成矿流体为幔源流体;含金石英脉中的金属硫化物硫同位素组成特征显示其以幔源硫为主,部分为壳源硫。因此认为,成矿物质可能主要来自地幔,部分来自地壳。成矿期前闪斜煌岩的修正年龄结果显示闪斜煌岩形成于燕山晚期早白垩世,由此推断马家窑金矿床也形成于这一时期。马家窑金矿床地质特征和同位素组成与山东栖霞山城金矿床相似,为典型的中温热液脉型金矿床。     

Impact of the Boeing 767 Aircraft into the World Trade Center

A numerical simulation of the aircraft impact into the exterior columns of the World Trade Center (WTC) was done using LS-DYNA. For simplification, the fuselage was modeled as a thin-walled cylinder, the wings were modeled as box beams with a fuel pocket, and the engines were represented as rigid cylinders. The exterior columns of the WTC were represented as box beams. Actual masses, material properties and dimensions of the Boeing 767 aircraft and the exterior columns of the WTC were used in this analysis. It was found that about 46% of the initial kinetic energy of the aircraft was used to damage columns. The minimum impact velocity of the aircraft to just penetrate the exterior columns would be 130?m/s. It was also found that a Boeing 767 traveling at top speed would not penetrate exterior columns of the WTC if the columns were thicker than 20?mm.     

EMDR Therapy Following the 9/11 Terrorist Attacks: A Community-Based Intervention Project in New York City.

This article presents the results of a time-limited psychological relief effort using eye movement desensitization and reprocessing (EMDR) following the attacks on the World Trade Center on September 11, 2001. Clients made highly significant positive gains on a range of outcome variables, including validated psychometrics and self-report scales. Analyses of the data suggest 2 broad conclusions: EMDR is a useful treatment intervention both in the immediate aftermath of disaster as well as later; the longer treatment is delayed, the greater the level of disturbance experienced by clients. Also discussed are problems in conducting research during mass disaster response situations. A demonstration of an analog to a wait-list control group is provided.
