Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Combining electrochemical and advanced oxidation processes (AOPs) has greatly mitigated the limitations of electrocoagulation (EC) in water treatment. This study examined the effectiveness of sonolysis (US)‐assisted alternating current (AC)–EC in reducing fluoride (F¯) from landfill leachate wastewater (LLW), with measurements of electrical ...

UV radiation and freshwater zooplankton: damage, protection and recovery
, 2010 While many laboratory and field studies show that zooplankton are negatively affected when exposed to high intensities of ultraviolet radiation (UVR), most studies also indicate that zooplankton are well adapted to cope with large variations in their UVR

On the freshwater shells of Tasmania [PDF]
Papers and proceedings of the Royal Society of Tasmania., 1875 No attempt has yet been made to arrange the freshwater shells of Tasmania. The land shells have been carefully catalogued by Mr. Legrand, so that little remains to be desired in that department of our island fauna. The marine shells have received much attention from most eminent naturalsts, though a list carefully criticised, with a well arranged
