His position, constructive empiricism, holds that the aim of science is empirical adequacy, where 'a theory is empirically adequate exactly if what it says about the observable things and events in the world, is true' (p. 12; p. 64 gives a more technical definition in terms of the embedding of observable structures in scientific models).
It was manually verified that the downsampling had little effect on the observable structures found in each tomogram.
The encrusting masses are up to 4 cm thick and lack any observable layered structure.
This review discusses current understanding of how the biochemical processes of ribosome biosynthesis relate to an observable nucleolar structure.
This suggests that the enzyme is in the nonactive conformation, which is supported by the observable lid structure of the enzyme (closed conformation).
Comparing with the control cells, the Sirt3-knockdown cells treated with irradiation had more dramatic changes in the mitochondrial ultrastructure, including the appearance of swollen or hydropic mitochondria, reduction in the amount of cristae or loss of observable crista structure.
There are indications that the thermodynamic orthorhombic to hexagonal transition Ttr is above 150 °C so that all the observable hexagonal structures are metastable.
In raphe formation, the first observable actin structures are filaments defining the SDV, and actin associated with the raphe appears later when silicification begins (Fig. 13).
Using both DNA sequence data and microsatellite markers, we tested the hypothesis that genetic partitioning reflects observable geographic structuring across Australia's mainland high country, in the widespread alpine grasshopper Kosciuscola tristis (Sjösted).
Our in vivo results confirmed that the endothelial cell barrier in MK2-deficient liver vessels appeared to be unable to mount a proper stress fiber response, as evidenced by the absence of increased actin density and changes in the observable actin structures after TNF challenge.
