For protecting a computer from manipulation of register contents, copies of registers to be protected are created in separate redundancy registers. This invention provides an isolated nucleic acid molecule of at least 15 contiguous nucleotides capable of specifically hybridizing with a unique sequence included within the sequence of the nucleic acid molecule encoding a MNR2 protein. , the tangential direction for an optical disc, compared to the direction orthogonal thereto, i. Zeolite-based SCR catalysts, which are used in particular in discontinuous SCR systems, constitute a very cost-intensive solution for the problem. Suppressed to \xb11% or less an on-plane distribution in thickness of a resist film to be applied onto a substrate in a graytone mask producing process.
