Abstract: Flocculation and deflocculation of fine sediment play an important role in soil structural stability, agrochemical compounds movement and eroded sediment transport.
The soybean phosphatidylethanolamine and phosphatidylinositol were prepared by combining methods of solvents extraction and silica gel column chromatography from soybean oil sediment.
Northeast is low-angle slope, develop constructive potamic-lake delta, The delta from headstream to lake, extend very long, sediment complex and Microfacies multiplicity.
Ultracentrifuge A high-speed centrifuge, operating at up to a million revolutions per second that is used to sediment protein and nucleic acid molecules.
We propose that As anomalism in groundwater possibly resulted from the combined effects of organic matter-enriched lacustrine sediments, geological setting and topographical characteristics.
The ubiquity of phenanthrene series, chrysene series compounds, perylene and retene compounds in the sediment indicated that PAHs mainly came from the terrestrial plants.
Its original rock is sedimented in the environment of active epicontinent-seaboard with basic volcanism, and become khondalite series through the Archean regional high-amphibolite facies metamorphism.
Benthos The organisms that live on the bottom sediments of freshwater and marine ecosystems. They include plants and algae (phytobenthos) that grow below low tide mark.
Using flow sediment laden formula set by Hanqiwei and overyear runoff,sediment data,the sediment retaining prediction of Manwan reservoir is carried out.
This rock contained chalcedonic cement before it underwent diagenesis, a process where low temperatures and low pressures alter the content of sediments before they finally lithify, or turn into rock.
Site soils in southern area of Jiangsu province belong to washland sediment or limnetic facies sediment.The components of sediment are very complex and process of sedimentation is in disorder.
