Interventional cardiologists are well aware of the utility of the buddy wire technique when stent delivery is difficult due to vessel tortuosity and calcification during PCI [2].
The calendering failed to significantly improve the WVTR due to densification of the coating layer causing a loss in tortuosity.
Low tortuosity values can have a slight stabilizing influence on the displacement.
We are in complete agreement on the fact that we confused the use of "tortuosity" and "tortuosity factor" terms (Epstein, 1989).
The complexity of the rock microfractographic network, in terms of connectivity and tortuosity, can be clearly identified.
It was fairly sensitive to the parameters of boundary soil water potential and tortuosity factor in macropores, whereas tortuosity factor in micropores and dispersivity were generally insensitive relative to the selected model output.
