snore loudly, and as she could not be roused, the door was forced, and the girl was found lying flat on the floor quite insensible, her breathing stertorous, eyes semi-closed, jaws locked, features distorted, and a stream of bloody froth running out from both the angles of the mouth, her muscles rigid, her dress saturated with urine, voided involuntarily, with violent convulsions occurring almo...

A new method was introduced for frothing characterization of flotation frothers. Method uses water recovery to develop a new frothability index named water recovery index (WRI). New index was determined for some commercial frothers and results were compared with dynamic frothability index (DFI). Results showed that water recovery index values follow the order of A-65 13016 s/mol > DF-250 6292.4...

Understanding the hydrodynamics of three-phase stirred tanks, such as froth flotation cells, is paramount for characterisation turbulence, stability and performance. Although positron emission particle tracking (PEPT) known its effectiveness in measuring particles opaque, high solid content systems, it has not been widely used characterising liquid phase. This work presents a new, neutrally buo...
