Use of micellar-enhanced ultrafiltration and ligand-modified micellar-enhanced ultrafiltration processes to remove dissolved metals and organic solutes from aqueous streams.
(1997)
The effectiveness of micellar-enhanced ultrafiltration (MEUF) and ligand-modified micellar-enhanced ultrafiltration (LM-MEUF) techniques for removal of heavy metal ions and/or organic pollutants from aqueous streams are ...
A comprehensive geological, geochemical, and petrogenetic study of hotspot-related oceanic basalt-rhyolite series rocks from Ascension Island, South Atlantic Ocean.
(1997)
The mafic rocks (basalt-hawaiite-mugearite-benmoreite) of Ascension Island form four distinct groups: low Zr/Nb hawaiite, high Zr/Nb basalt, intermediate Zr/Nb basalt to benmoreite, and Dark Slope Crater (DSC) hawaiite and ...
Recent interdecadal variations in the tropical atmosphere: Evidence and idealized GCM simulations.
(1998)
A series of model integrations, forced with different SST perturbations over the tropical central and eastern Pacific, has been performed using the ECHAM4 GCM in an attempt to simulate the spatial patterns in tropical ...
