2An eco-environmental friendly operation: An effective method to mitigate the harmful blooms in the tributary bays of Three Gorges Reservoir显示文摘Harmful algal blooms, which frequently occur in different tributaries, have become a serious water quality problem of the Three Gorges Reservoir (TGR) since its initial filling. A three-year monitoring campaign from 2008 to 2010 was conducted to identify the controlling factors of algal blooms and effective preventive measures. The following results were obtained: 1) Layered and bidirectional currents, called intrusive density currents, dominate the tributary bays of the TGR year round; 2) continuously increasing water level can make the intruding density current shift from the middle to the surface, and surface intrusive water can reduce the surface water temperature and break the stable stratification of the tributary; 3) the appearing or fading away of algal blooms is closely associated with fluctuations in the TGR water level. Thus, the water level fluctuation patterns of different 'tide-types' may prevent the occurrence of algal blooms in the spring and summer, and the 'stair-type' tides may control autumn blooms during the impounding period. These methods were feasible and effective throughout the actual TGR's operation in 2009 2011. These patterns formed an eco-environmentally friendly operation (EEFO) to mitigate algal blooms. As an in situ treatment with easier operation and less negative impact and loss, compared with chemical and filter-feeding fish methods, the EEFO is currently considered as the most feasible remedial measure to remit the eco-environmental problems at the Three Gorges Dam (TGD).YANG ZhengJian LIU DeFu JI DaoBin XIAO ShangBin HUANG YuLing MA Jun 2013Science China(Technological Sciences)2013,56,6:14

7抗氧化和长期抗菌活性迷迭香酸明胶生物降解膜的研制显示文摘开发新的方法将天然活性物质加入到凝胶基的食用薄膜中,以获得有效的抗氧化和长期的抗菌活性,具有重要的意义.在这里,天然活性化合物迷迭香酸(RosA)首先通过EDC/NHS化学结合在明胶骨架上.然后用甘油偶联物进行塑化,并与二醛黄原胶交联,制备活性RosA-明胶食用薄膜.结果表明,该食品膜具有良好的耐水性能、较强的力学性能和较好的紫外光阻隔性能.RosA的共轭使以明胶为基础的可食用薄膜具有预期的有效抗氧化和抗菌活性.有趣的是,经过3个月的贮藏后,RosA-明胶食用膜仍具有较好的抗菌活性,显示出较长期的抗菌活性.总之,所制备的RosA-明胶食用薄膜在食品和医药包装领域具有广阔的应用前景.Liming Ge Mingjin Zhu Xinying Li Yongbin Xu Xiaonan Ma Rong Shi Defu Li Changdao Mu 2018绿色包装2018,0,7:0
