This large-scale voids in the sub-surface can initiate collapse of the overburden, either through wall or roof breakdown, and the initial void created by dissolution can migrate upwards and finally cause a surface collapse and create a collapse sinkhole.
In practice, this load is very important for crashworthiness design that gives an indication of the force required to initiate collapse and hence begin the energy absorption process.
Moreover, the robust ROS attacked the mitochondria to initiate collapse of the mitochondrial membrane permeability and the exportation of apoptosis-inducing factor (AIF), IAP-binding mitochondrial protein (SMAC/DIABLO) and cytochrome c.
"His 5-44 included three quick wickets that initiated their collapse, losing eight wickets for 66 runs.
"I didn't initiate the collapse of the movement, but I had to initiate the separation of my family," she said.
However, other factors, including humans can induce sinkholes to form, such as: Heavy rain or surface flooding can initiate the collapse of normally stable cavities, especially those developed within superficial deposits.
But the investigators still believe that the floors may have played a role in initiating the collapse, perhaps simply because the various tests show that the floors sagged a great deal during intense fires, which may have been enough to undermine already weakened outer columns.
It takes many millions of solar masses (but under a billion) to initiate gravitational collapse down to stars for the primordial material in the Universe, which means that even the densest regions of all won't develop stars until many tens of millions of years have passed.
More specifically, we consider a nonrotating star with central rest-mass density (8 times10^{-3}~M_{odot}^{-2}), corresponding to a baryon mass of (1.5~M_{odot}) and radius (6~M_{odot}), and initiate the collapse with a velocity perturbation analogous to the one used in the migration test, but with the opposite sign, i.e., radially ingoing.
These semaphorins were originally characterised in the developing nervous system, dorsal root ganglion, peripheral and sympathetic nervous systems as chemorepellent molecules that acted to initiate axonal collapse in areas that they were found in high concentration, thus resulting in axonal guidance [ 29- 31].
Simulations sampling different flow velocities reveal that under flow, β-hairpin folding is initiated by hydrophobic collapse, followed by interstrand hydrogen-bond formation and turn formation.
