, as well as laminae arranged in the container, said laminae having wavy convex and concave areas, and a screw conveyor in the bottom of the container, the invention proposes that aerating jets are arranged in the area of the screw conveyor for the introduction of gas into the sediment....
Dredging vessel to clear Wells Harbor channel ; The Currituck will remove about 10,000 cubic yards of sand and sediment at the end of the jetty.JEN FISH Staff Writer
s A laboratory based empirical assessment of hydraulics of sand filters was carried out under the compelling practical condition of exposure to alternate cycles (wet and dry spell) of filtration. The lab-scale simulations purportedly attempted to mimic the field scale condition of sediment loading in...
Field adaptation of these findings involves use of CS beds of 0.7-1.0 mm particle size and minimum 75 cm thickness as the top layer in recharge filters and providing a sediment tank or biological filters near the recharge structures to reduce sediment load of run-off water before entering the...
The physio-chemical properties of such deteriorations were measured by means of three distinct test procedures: saltwater aquarium, reactor with sandy sediment and two-phase marine medium testing. It was observed that the degradation quantum depends on the specific marine environment and testing ...
U-Net;methane hydrates;microtomography;sediment microstructure;semantic segmentation 1. Introduction Deep sea sediments and perfmafrost host large quantities of methane (CH4), an energy source and potent greenhouse gas that may be a contributor to climate change [1,2]. Much of this CH4is present ...
beach sand (wet—coastal bottom sediment, humid—vadose zone sand, dry—supratidal sand), and pH (seawater, sand extract). The variables of the second kind record the presence and abundance of fungal species and taxonomical groups (genera, phylum, etc.), as well as functional/non-taxonomical...
