The influence of mercury and lead on cadmium accumulation was investigated by exposing the fish Oreochromis aureus, or Blue Tilapia, to two heavy metals simultaneously. The chronic accumulation profile of cadmium in the liver, brain, gill filaments, intestine, caudal muscle, spleen, trunk kidney, and gonads was determined for exposure to cadmium alone and(More)
This paper explores the metaphor of animism as a methodological framework for interaction design and, in particular, advocates for a form of animism the authors term 'heterogeneous multiplicity.' Animism can make valuable contributions within ubiquitous computing contexts, where objects with designed behaviors tend to evoke a perception that they have(More)

The interaction of mercury and cadmium with lead was investigated by exposing Oreochromis aureus to two heavy metals simultaneously. The chronic accumulation profile of lead was determined by analyzing the liver, brain, gill filaments, intestine, caudal muscle, spleen, trunk kidney, and gonads following exposure to lead alone and in mixtures with mercury(More)

The effects of cadmium and lead on chronic mercury accumulation were investigated in O. aureus. After 140 days' exposure the accumulation of mercury in the liver, brain, gill filaments, intestine, caudal muscle, spleen, trunk kidney and eye was analysed. The exposure concentrations were 0.05, 0.10 and 0.20 mg/L for mercury alone. O. aureus was also exposed(More)
