Stenoses of the branches of the pulmonary arteries were enlarged with a pericardial patch in four patients.
These results arose from patches that were unforeseen.
The angiosarcoma, due to its invasive nature, required extensive resection, after which pericardial patches were needed to reconstruct the right atrium and the septum.
The repair consisted of double patch closure of the septal defect, reconstruction of two atrioventricular orifices, and relief of pulmonary stenosis at all levels.
In this case, the intense perturbation of the upper boundary favours the generation of downstream patches of vortices travelling with high phase velocity.
These were determined using a circular patch of drifting sinusoidal grating of modest contrast.
This requires natural enemies to eliminate sparsely distributed patches of prey, so that prey spatial distribution is very relevant to the success of biological control.
Two-dimensional singular surfaces generated by different sets of four constraint equations intersect at many onedimensional curves that divide the surfaces into many two-dimensional patches.
