Doing so, once soil model was analyzed with single stone column of diameter 1 m at center of model with lower permeability (equal to surrounding soil permeability) without considering drainage boundary in stone columns environment with the same acceleration time history of VELACS project.
Each trial began with a fixation point (the picture of an eye) shown for 1000 ms at the center of the screen.
These studies showed the face alone for 1000 ms at the center before presenting the peripheral stimulus, which was approximately 14 degrees to either the left or right of the center.
First, a precue was presented for 1000 ms at the center of the screen to indicate the region where the lexical stimulus would be presented.
On each trial a homogenous grey screen was first displayed for 250 ms and a 1300 Hz pure tone accompanied this grey screen for the first 122 ms. The grey screen was immediately followed by a dynamically bubbled word displayed for 200 ms at the center of the screen.
Each trial started with a fixation cross, presented for 1,000 ms at the center of the computer screen.
Feedback in the form of the word "Wrong" presented for 500 ms at the center of the screen followed incorrect memory responses.
Immediately following the presentation of the fixation dot, a word cue presented in white was displayed for a period of 850 ms at the center of the screen.
All the visual stimuli were presented for 200 ms at the center of monitor, with a visual angle of 2.58° × 2.4°.
Soil samples were collected from 5 m × 5 m subplots nested with in the 10 m × 10 m at the center of the main plots.
