David, a local birder, pointed out the peregrine on the pylon one morning in late September; it was mantling over a wood pigeon on the lowest crossarm, 15 metres up.
As neighborhood teen- agers gathered to watch, she pulled out a stencil the size of an ostrich egg, traced an oval on the pylon, and filled it in with white gesso.
The actuation system has the potential to move up or down on the pylon to accommodate the users' residual limb or to optimize the weight distribution and inertia characteristics.
This showed differences in the strain on the pylon between the experimental and the numerical model within 30% for the anteroposterior bending and up to 25% for the compression.
In particular, the results of the computer simulations are employed to characterise the type and extent of damage on the pylon and deck, and additionally to investigate the potential cable loss scenarios associated with a loss of anchorage.
Reflecting on the pylon controversy, the CEO of EirGrid conceded that the "national grid operator obviously did not do a good job explaining to communities that the power lines would not be used to export help export power from large-scale wind farms proposed for the midland 21.
