Using in-depth interviews with Asian-American professionals from various metropolitan areas, this study investigates these professionals' perceptions on minority invisibility and model...

"Electrochemistry of Flotation of Sulphide Minerals" systematically covers various electrochemical measurements, especially electrochemical corrosive methods, electrochemical equilibrium calculations, surface analysis, semiconductor energy band theory as well as molecular orbital theory. Behaviour and mechanism of collectorless and collector-induced flotation of sulphide minerals in various flotation systems are also discussed. The example of electrochemical flotation separation of sulphide ores shows an industrial application.
