A protective film on a conductor, where a contact hole is to be formed, is removed in advance in a forming process of an etched-away opening to expose the top portion of the corresponding conductor from the top surface of an insulating film, which has buried therein the conductor covered with the protective film. The composition includes an effective amount of at least one glutaminase inhibitor. The simulated first monochromatic contrast-enhanced X-ray image includes first regions of enhanced contrast and the simulated second monochromatic contrast-enhanced includes second regions of enhanced contrast. The first restricts lateral and rotational motion, the second restricts rotational motion and lateral motion in one direction while permitting motion in a transverse direction, and the third floating mounting permits rotational and lateral motion, to a limited extent. , in order to take into account the position of the brochure cover on the book block at the spine edges. Storage utilization reports which simultaneously display a plurality of storage category levels, and compute designated and free storage capacity at each level, indicate underutilized or potential available storage which may be obscured by imprecise or overly generous storage allotment estimates.
