WitrynaThe compartment intensities, as percentage of sunlight in the open, were 22 per cent, 11 per cent and 6 per cent. Fans (Plate 3) operated at reduced speed gave a gentle air circulation through the compartments. To modify the quality of the radiation a water- filter was placed over some of the plants in the "50 per cent" area (Plate 4). WitrynaThe processes occurring during zinc immersion plating of aluminium have been studied in alkaline medium. The mechanism of immersion zinc deposition on aluminium has been elucidated by studying the kinetics of the partial electrode reactions involved in this complex process. The diffusion of zincate ions has been shown to play a decisive role …
