Inter and intra-population variation in shoaling and boldness in the zebrafish (<Emphasis Type="Italic">Danio rerio</Emphasis>)

Population differences in anti-predator behaviour have been demonstrated in several species, although less is known about the genetic basis of these traits. To determine the extent of genetic differences in boldness (defined as exploration of a novel object) and shoaling within and between zebrafish (Danio rerio) populations, and to examine the genetic basis of shoaling behaviour in general, we carried out a study that involved laboratory-raised fish derived from four wild-caught populations. Controlling for differences in rearing environment, significant inter-population differences were found in boldness but not shoaling. A larger shoaling experiment was also performed using one of the populations as the basis of a North Carolina type II breeding design (174 fish in total) to estimate heritability of shoaling tendency. A narrow-sense heritability estimate of 0.40 was obtained, with no apparent dominance effects.     

陶瓷微滤膜过滤黑液的清洗与再生

对无机陶瓷微滤膜过滤草桨黑液的膜清洗及再生的方法进行了研究。考察了物理和化学方法的再生效果、单种清洗剂的清洗效果、复合方法的清洗效果和效果的可重复性。结果表明物理冲洗、高温灼烧、单一的化学清洗剂清洗均可以提高陶瓷膜的再生通量；但是复合方法对陶瓷微滤膜的再生效果较好，其中按氢氧化钠溶液清洗、硝酸溶液清洗、次氯酸钠溶液清洗的实验步骤，膜的再生渗透通量高．且重复性强，可望在工业生产的在线清洗中应用。     

混凝法在滇池蓝藻暴发期净水除藻的可行性研究

采用精制硫酸铝为混凝剂,L93^4正交法安排滇池蓝藻暴发期混凝沉降除藻除净水工艺实验。结果表明,混凝剂种类、水样pH值对蓝藻去除率有很大影响。研究确定了混凝剂除藻最佳操作条件,为混凝法去除蓝藻的工业化提供了理论和实际操作依据。

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.     

以CaS为燃煤固硫产物的热力学可行性和实验探索

高于１２００℃的燃煤固硫因ＣａＳＯ４的分解而因硫效率不高。ＣａＳ在高温下不会分解，若以ＣａＳ形式能将硫分固定下来，可以大大提高固硫效率。从热力学研究着手，计算预测了以ＣａＳ形式固硫的可行性；在富煤还原气氛燃烧时，在高于１２２７℃可达９０％的固硫效果；在贫煤燃烧时，由于局部存在还原气氛，也可达到一定的固硫效果。本文实验表明，固硫剂中的某些非钙基添加剂可以在高温下形成玻璃态物质，更好地抑制ＣａＳ的氧化

从宿迁地震台情况探讨观测环境的保护

在地震观测中，环境保护是非常重要的，可是随着改革开放后我国经济的飞速发展，各级政府在进行经济建设的过程中，很多地方地震观测环境受到很大的影响。我们江苏省宿迁地震台的观测环境目前就处在这种境况之中，这给我们的数据采集带来了很大的影响。本文从我台环境受影响的现状、国家的法律法规、解决的思路等方面探讨问题的解决办法。
