Blood oxygen-binding characteristics of bigeye tuna (Thunnus obesus), a high-energy-demand teleost that is tolerant of low ambient oxygen Abstract We found blood from bigeye tuna (Thunnus obesus) to have a signi®cantly higher O 2 anity than blood from other tunas. Its P 50 (partial pressure of oxygen, P O 2 required to reach 50% saturation) was 1.6 to 2.0 kPa (12 to 15 mmHg) when equilibrated ...

This view leads to a hierarchy of the form observations < system description < fault model, between the various knowledge sources. It turns out that the semantics for ordered logic programming nicely fits this intuition: if the observations cont...
