Electronegative and electropositive filters were compared for the recovery of indigenous bacteriophages from water samples, using the VIRADEL technique. Fiber glass and diatomaceous earth filters displayed low adsorption and recovery, but an important increase of the adsorption percentage was observed when the filters were treated with cationic polymers (about 99% adsorption). A new methodology...

Heavy rare earth elements (HREE) are dominantly mined from the weathering crusts of granites in South China. Although weathering processes occur globally, no economic HREE resources of this type have yet been found outside China. Here, we report the occurrence of unidentified REE minerals in the granites from South Chinese deposits. They contain high levels of both HREE and light REE, but are s...

The Grid and emerging e-collaboration computing services are considered as powerful new instruments, enabling and strengthening remote collaboration among researchers. For example, a Gridbased infrastructure can permit alternative approaches to access and exploit large data sets. Instead of traditional remote sensing data ordering and delivering from the acquisition/storage facilities to the us...
