An object of the present invention is to provide an anti-constipation composition containing a halogenated-bi-cyclic compound as an active ingredient in a ratio of bi-cyclicmono-cyclic structure of at least 1:1. The dielectric barrier is therefore a self-forming, self-aligned barrier. The pixels of the image are converted to gray scale. The method includes identifying one or more functional blocks andor properties of software. The axial catch and the stop elements are embodied such that they can be moved past each other in axial direction. A component wave GAj corresponding to the narrow band spectrum FAj is obtained by inverse Fourier transformation.
