天津港深水亨白位移位疏浚工艺研究与应用

移位疏浚，是在货船驶离码头的短暂空闲时间内，迅速将泊位内侧海底淤浅泥沙移至泊位外侧；在码头靠泊货船条件下，将泊位外侧海底泥沙挖走，这是在不影响码头正常作业条件下，完成泊位水深维护疏浚任务的一种新工艺。

合生元对烧伤大鼠肠源性感染的影响

目的 探讨合生元治疗烧伤后肠源性感染的机制,为烧伤后肠源性感染的防治探求新途径。方法 动态检测大鼠体内的肠道示踪菌JM109易位率和血浆中LPS水平。结果 合生元治疗组大鼠体内JM109易位率以及血浆LPS水平明显低于烧伤对照组。结论 合生元能够快速补充肠道生理性厌氧菌,坚固肠粘膜外微生物屏障,阻止肠道条件致病菌和LPS经肠壁进入机体组织,对烧伤后肠源性感染有一定的预防和治疗作用。     

迪拜哈斯彦电站码头及GRP管道工程环境保护举措

迪拜政府对位于野生动物保护区内的哈斯彦电站海工项目施工作业提出了极高的环保要求,项目团队对当地政府的各项环保承诺是该项目开工许可获批的前提条件。阐述了以下问题:在项目属地周边无类似经验可供参考的情况下,从项目勘察设计到施工阶段,如何积极探索并有效解决各类环境和生态保护方面的问题,并最终从当地政府获取CEMP等相关环保文件的批复;以及在该项目开工前和施工过程中,如何实施迪拜政府要求的各项环保措施。     

Seaport Development and Coastal Management Programs: A National Overview

Oysters have been harvested on the east coast of Australia for many thousands of years. Coastal Aboriginal communities used the extensive estuarine oyster resource and may have farmed oysters by establishing shell cultch beds in shallow areas of estuaries. The British colonization of Australia commenced in 1788 and oysters were initially used for food and production of lime. Concerns about unsustainable exploitation led to introduction of legislation that directed the oyster industry to aquaculture in 1884. Translocation of oyster stock for fattening, from New Zealand to Australian east coast estuaries, was encouraged. Here evidence is presented that this activity resulted in “mudworm disease” appearing in oyster farming estuaries on the Australian east coast between 1880 and 1900. The pandemic permanently destroyed natural sub-tidal oyster reefs and forced the oyster industry to adopt avoidance farming techniques including intertidal farming to cope with mudworm.
