Ion cyclotron instability due to the thermal anisotropy of drifting ion species
(Blackwell Publishing Ltd, 2003)
In a recent study of ion cyclotron waves generated by the thermal anisotropy of oxygen ions, it was shown that the heavy ion drift velocity and a large thermal anisotropy of the heavy ions can destabilize proton-cyclotron ...
Zinc and lead content and availability in Brazilian soil contaminated with residue of a secondary smelting lead recycling plant
(2012-07-30)
The sequential extraction procedure of Zinc and lead performed in a Brazilian soil showed that it presents high pollution potential once over 90% of total lead is present in fractions where the metals can be easily mobilized. ...
