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.
Later, vaults were designed and manufactured specifically for this purpose. You will find that different styles of vaults were used at different periods of time and in different geographical areas. In general however, many U.S. cemeteries began using six piece or sectional vaults somewhere around the early 1900âs. These six piece vaults were initially cut from slate and assembled in the open grave.
