When deep cement mixing method (DCM) uses as solidified material to treat marine soft foundation, the strength of soil is different due diversity water content, void ratio and particle fineness. Based on Pearl River Estuary DCM project, this paper a variety PO.42.5 in estuary area carry out indoor mix proportion tests. There are four kinds soil: flowing mud, silt, muddy silt. The test results s...

Two major projects in the U.S. and Europe have joined in a collaboration to work toward achieving interoperability among language resources. In the U.S., a project entitled ”Sustainable Interoperability for Language Technology” (SILT) has been funded by the National Science Foundation under the INTEROP program, and in Europe, FLaReNet Fostering Language Resources Network has been funded by the ...

The direct fluorescent-antibody technique was employed to determine the distribution patterns of four species of methanogens in the sediments of Lake Erie and Cleveland Harbor. Methanobacterium ruminantium was the most numerous methanogen found in regions of high-organic-silt sediments. The population of this species ranged from 10 to 10 cells/g of dry sediment. Methanobacterium strain MoH and ...

The performances of the standard Petersen, Ekman, and Ponar grabs were compared using 2 sets of samples collected from gravel, sand, silt, and mud substrates. The data obtained during this study show that estimates of macroinvertebrate populations may vary considerably depending on the grab utilized, the nature of the substrate, and the number of replicate samples collected. The Ekman sampler w...
