For example, those single taxpayers with $5,000 of Social Security benefits in the example above would see their marginal tax rate on nonâSocial Security income boosted by 50 percent if their modified AGI was between $25,000 and $30,000 and by 85 percent if their modified AGI was between $34,000 and $36,000.
Three types of vault were commonly used: the barrel-vault, the groined or four-part vault, and the dome. The barrel-vault was generally semi-cylindrical in section, and was used to cover corridors and oblong halls, like the temple-cellas, or was bent around a curve, as in amphitheatre passages.
Why are burial vaults and grave liners necessary? Cemeteries often require a burial vault or a grave liner to enclose the casket in a grave. The vault or liner is used to prevent the ground from caving in as the casket deteriorates. Burial vaults are considerably more expensive than liners.
