Startup Characteristics of Dredging Thermal Protection Structures

气体物理
Dredging thermal protection, as a semi-active thermal protection method, is characterized by its simple structure and the absence of the need to carry additional coolants, making it suitable for the leading edge thermal protection of hypersonic vehicles.

Sediment Resuspension and Deposition on Seagrass Leaves Impedes Internal Plant Aeration and Promotes Phytotoxic H2S Intrusion

Frontiers in Plant Science, 2017
HIGHLIGHTS:Sedimentation of fine sediment particles onto seagrass leaves severely hampers the plants' performance in both light and darkness, due to inadequate internal plant aeration and intrusion of phytotoxic H2S.Anthropogenic activities leading to ...

The aeration and dredging stimulate the reduction of pollution and carbon emissions in a sediment microcosm study

Scientific Reports
Sediment dredging and aeration are used as important technical measures to remediate internal loading of sediment in polluted rivers. However, previous studies have overlooked the impact of dredging and aeration on Greenhouse gases (GHGs) emission.
