The present invention discloses a metallocene catalyst component based on a Group IIIb metal of the periodic Table and a bridged heteroatom-fluorenyl ligand. The compacted product has an improved bulk density and improved wet out and slurry incorporation times as compared to the non-compacted starting material feed. Each of the upper and lower parts also has a surface engaging an adjacent vertebrae. This effect says, The deoxygenation of the blood increases its ability to carry CO2. Particularly when the gird bar and foraminous interface member are present, there can be internal support members for the cathodes directly secured to the inside face of the cathode sidewall. 2, wherein R1 is an alignment ratio of the catalyst layer; and R0 is an alignment ratio of the catalyst material in powder form having a random crystalline plane distribution, and each of the alignment ratios is calculated from a X-ray diffraction spectrum having a diffraction angle 2\u03b8 range from 10 to 90 degree measured using Cu-K\u03b1-rays.
