老红星桥拆除施工

为了达到安全、顺利、快捷、环保的目的,且施工过程尽可能减少对京杭大运河航运的影响,采用逆向工序法进行老红星桥拆除,即按造桥时悬臂浇筑节段划分反向切割、吊运拆除。对拆除施工进行监控,结果表明应力和变形均满足相关要求。老红星桥的顺利拆除表明,该施工方法取得了理想的效果。     

矽肺患者血液流变学研究

对５６名Ⅰ期、４４名Ⅱ期矽肺患者作了反映红细胞变形、聚集状态，Ｃａｓｏｎ屈服值改变及血粘度的血液流变学检查。结果表明，高粘滞血症、红细胞聚集增强、红细胞变形能力低下、Ｃａｓｏｎ屈服值增高是矽肺患者血液流变学异常改变之特征。

Biological effects of dilution of Dead Sea brine with seawater: implications for the planning of the Red Sea–Dead Sea “Peace Conduit”

The Dead Sea is a severely disturbed ecosystem. Its water level has been decreasing at a rate of nearly 1 m per year during the last decade due to anthropogenic intervention in its water balance. Since the peace treaty between Israel and Jordan was established in 1994, a proposal for the construction of a water carrier, the “Peace Conduit,” between the Gulf of Aqaba (Red Sea) and the Dead Sea is being investigated. This water carrier is intended to mitigate damaging processes that currently occur in the Dead Sea and its surrounding area. The difference in elevation of about 416 m could be exploited for seawater desalination by reverse osmosis. To examine the possible effects of the mixing of Dead Sea brines with seawater and seawater concentrates on the Dead Sea as an ecosystem, we have set up simulation experiments under field conditions in experimental ponds at Sedom, in which Dead Sea water was diluted with Red Sea water. The main components of the Dead Sea biota are the unicellular green alga Dunaliella and several types of red halophilic Archaea. Phosphate is the limiting inorganic nutrient. Massive Dunaliella blooms developed, accompanied by dense communities of red halophilic Archaea, in some of the experimental ponds, imparting a brown-red coloration to the brines. The extent of biological development depended on the extent of dilution and on phosphate availability. The results of the simulation experiments show that biological phenomena and their impact on the Dead Sea ecosystem should be taken into consideration during the planning of the “Peace Conduit.”
