The epic tale of everyone's favorite dark elf, Drizzt Do'Urden, reaches new heights! Drizzt Do'Urden struggles with his own inner voices, voices that call him back to the pitiless depths of the Underdark.
But louder still are the voices of his newfound friends, and the dream that drives Bruenor Battlehammer on to reclaim Mithral Hall.
Time and again they're told to turn back, that some dreams can never be fulfilled, but on they fight -- together. From the Paperback edition. Fantasy Fiction.

Carboplatin was only partly recovered max. Transmission electron microscopy TEM revealed the presence of both intra- and extracellular platinum particles. Flow cytometry based microbial viability assessment demonstrated the decrease in number of intact bacterial cells during platinum reduction and indicated C.
This study showed the effective and complete biological recovery of three common Pt-complexes, and estimated the fate and transport of the Pt-complexes in wastewater treatment plants and the natural environment.

Introduction The growing importance and use of platinum in clean and high-tech products in the last 30 years have induced the production of Pt loaded waste streams and the accumulation of platinum in the environment [ 1 , 2 ].
For example, deterioration of automotive catalysts leads to the emission of Pt particles into the environment, part of which gets drained by stormwater into sewers [ 3 ]. Platinum is also the crucial building block of chemotherapeutic drugs such as cisplatin and carboplatin, and the excreted human metabolites contaminate both hospital and municipal wastewaters [ 1 ].
Finally, liquid waste streams often diluted containing platinum are also produced from the application of industrial catalysts, the manufacturing of jewelry and electronics, and both primary mining and precious metal recovery activities [ 2 , 3 ]. The resulting residual platinum appears in different complexes in wastewater, with inorganic or organic ligands, such as cisplatin cis-PtCl2[NH3]2 , carboplatin cis- Pt[NH3]2[1,1-cyclobutanedicarboxylato] , and their metabolites, chloro-complexes Pt II Cl and Pt IV Cl or amine-complexes such as Pt NH3 4Cl2, resulting from leaching or metal refinery processes [ 4 — 6 ].
An effective removal of the precious metal is advised to both lower the pollutant load in the environment, based on the pollution prevention principle, and since the behavior and impact of species such as cisplatin is mainly unknown in the environment [ 7 ].
Case by case, it should be questioned if the targeted Pt-complex could be removed and recovered from the waste stream, and whether this recovery could be interesting from an economical point of view [ 2 ]. Biotechnologies based on living biomass can serve as low-cost and green treatment techniques to recover platinum at low concentrations [ 11 , 12 ].
The effective removal of platinum by different axenic cultures has been demonstrated before; PtCl and PtCl were sorbed by Shewanella putrefaciens [ 12 ], PtCl was reduced by Shewanella algae [ 13 ] and an undefined Pt-complex was reduced by Cupriavidus metallidurans [ 14 ]. However, the metal speciation can hamper an effective metal removal [ 2 ]. Complex waste streams such as highly acidic saline streams originating from metal refinery processes can be considered too challenging for conventional biological wastewater treatment plants WWTP.
They require specialized mixed cultures adapted to the prevalent conditions [ 11 , 15 ].
