Mitigation of the Impact of Tropical Cyclones in Northern Australia through Community Capacity Enhancement

Community mitigation of hazard impact requires hazard knowledge and preparedness on the part of the members of diverse and complex communities. Longitudinal research in the tropical cyclone prone north of Australia has gathered extensive datasets on community awareness, preparedness and knowledge, in order to contribute to education campaigns and mitigation strategies. Data have been used to identify issues of vulnerability to cyclones and capacity to deal with the hazard. This has been developed as a community vulnerability and capacity model that may be applied to diverse communities in order to assess levels of capability to mitigate and deal with the cyclone hazard. The model is presented here in a simplified form as its development is evolving and ongoing.     

钙镁磷肥对土壤中镉形态转化与水稻吸镉的影响

酸性镉污染水田施用不同用量的钙镁磷肥的田间试验表明:土壤中交换态镉的分配系数随钙镁磷肥用量的增加而降低,呈显著负相关(r,-0.9314);碳酸盐结合态和铁锰氧化物结合态镉的分配系数则呈显著正相关(r,0,9395)。而土壤中有效态镉含量与钙镁磷肥用量则呈显著负相关(r,-0.8853)。镉污染水田一次性投加高量钙镁磷肥后,可使土壤pH显著升高,交换态镉分配系数明显下降,碳酸盐结合态和铁锰氧化物结合态镉分配系数明显升高,导致土壤中有效态镉含量大幅度下降,从而大大减少水稻植株的吸镉量。

Analysis of the Henze precipitate from the blood cells of the ascidian<Emphasis Type="Italic"> Phallusia mammillata</Emphasis>

The Henze precipitate, a peculiar blue-green microparticulate obtained by lysis of the blood cells of the ascidian Phallusia mammillata (Protochordata), was investigated with atomic force microscopy (AFM), scanning electron microscopy (SEM) and X-ray microanalysis. The precipitate was collected from the Henze solution, an unstable red-brown product obtained by treating blood with distilled water, whose degradation yields a characteristic blue-green product. The microparticulates measured 50–100 µm in diameter and appeared irregular in shape. SEM examination showed smooth, roughly round boundaries. The microparticulate surface examined with AFM appeared as an irregular matrix formed by 70–320-nm-wide mammillate composites, including and embedding small (500–800 nm wide) crystal-like multilayered formations. X- ray analysis showed that the elements present in these same precipitates were mainly C, Si, Al and O. The microparticulate composition appeared close to those of natural waxes or lacquers, embedding amorphous silicates and/or other Si–Al components. The unusual occurrence of Si in ascidian blood and its role are discussed.     

永梅会与中下扬子地区的成矿条件对比

永海会地区的区域构造、含矿地层和建造、中生代火山侵入岩体特征、局部控矿构造以及成矿物质来源、硫氢氧同位素、铅同位素、年龄同位素等成矿信息，都与扬子区、萍乐区已知铜金矿集区有许多相似之处。通过对比表明，永海会地区具有极大的找矿前应景。

污水海洋（江河）处置工程喷口的冲淤规律

结合上海市合流污水治理二期工程排放管稀释扩散规律及泥沙冲淤规律的研究，利用少运动相似理论，通过模型试验，从环境泥沙积在上管喷口上的最不利条件出发，分析喷口对泥沙的冲液规律，提出喷口冲淤临界速的概念，并据此提出适宜的上升管高度及喷口射流角度。

上海地区高空气流长距离输送轨迹及其与酸雨的关系

分析了影响上海地区的高空气流输送轨迹。不同月份影响上海的高空气流来向不一。轨迹输送路径与天气系统的变化密切有关,且与上海地区出现的酸雨有关。研究表明,上海地区的酸雨,除与局地污染有关外,还与远处输送的外来污染有关。这些外来污染影响,主要来自上海西南向的北部湾和两广等地。也有部分来自东北——东方向的南朝鲜和日本西部地区。
