thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
1. Oxygen uptakes from air and water have been measured in relation to weight of the African lungfish Protopterus amphibius Peters. 2. Combined O2 uptake from air and water ranged from 60 ml O2 kg-1 h-1 STPD, in a 3-7 g specimen, to 30 ml O2kg-1 h-1, in a 255 g specimen. 3. While the combined O2 uptake changed by a factor of 2, within the weight range under study, the aquatic O2 uptake changed ...
