Immediately after impact, the stress on remaining columns shot up, over a butterfly-shaped pattern around the impact zone on the facade and throughout the core.
Of the thousands of remaining columns, not many more than 50 stand erect, and amid the ruins are Christian churches, thickets of trees and bushes, and hundreds upon hundreds of free-living cats.
This brutal conjunction of beauty and violence – the remaining columns of the ancient city gold-hued against the leaden plume of destruction floating in the pure blue sky – is an image of sheer fanaticism, unbridled hatred, and the obliteration of everything anyone has ever called civilised.
Many remaining columns need bracing themselves and some floors are unstable, said Irene Chang, a vice president of the Lower Manhattan Development Corporation, which is working on the demolition plan with the Port Authority of New York and New Jersey, the Tishman Construction Corporation and Voorsanger & Associates Architects.
Even though a large swath of outer columns in both buildings' facades had been blown out, the stress on the remaining columns rose to about 50percentt of their capacity in zones at the top of the towers, and to more than 90percentt in spots next to the impact holes, one study done for the insurance lawsuit has shown.
The remaining columns in Table 3 investigate the robustness of the previous finding.
It starts from checking if the list of remaining columns (i.e. Mat) is empty (line 8).
Remaining columns show the observed misclassification error rate for each of the algorithms.
Then, it is recovered by simply modulo-two addition of the remaining columns.
The remaining columns of Table 5 check the stability of the estimates across different versions of the same equation.
The remaining columns are a cross-tabulation of the self-reported and quantitative measures of the entire estimation sample.
