Feasibility of humic substances removal by enhanced coagulation process in surface water
Aims: This study evaluates the effectiveness of polyaluminium chloride (PACl)as a coagulant for enhanced coagulation (EC) of humic substances (HS) in surface water. Materials and Methods: Dissolved organic carbon (DOC), ultraviolet absorbance (UV 254 ),

Divergent evolution of colony-level metabolic scaling in ants. [PDF]
The study shows for the first time that the metabolic scaling of active ant colonies varies as a function of trophic level and worker polymorphism. Therefore, the ecological divergence of metabolic scaling observed in unitary organisms occurs across levels of biological organization.
