Propagation time of any pulse is roughly the time needed for the leading edge of the pulse to travel from one point to another. It will be more accurate to say that the pulse is registered at a given point when its leading edge reaches half of the maximum value (amplitude) of the pulse. The propagation time of a sound pulse is equal to the distance between the measuring points divided to the sound velocity in the medium in which it propagates.

In most setting evangelism on the part of nurses is prohibited. However, they can be an effective missionary of sorts by modeling Christ-like behavior as servant.

Propagation means triggering ie something which fires automatically. Thepropogation of operation is applied with aggregation, if some operation is applied with the high level aggrigate the same operation will be performed with all lower aggregates. For example in aggregation between document and paragraph if we will perform an operation copy with document it will automatically applied with paragraph also. This propagation of operation.
