The scanned image registration systems and methods according to this invention register sets of scanned subimages of an original document into a composite scanned image of the original document. The method includes receiving three-dimensional volumetric scan data from a scan of the container, reconstructing a three-dimensional representation of the container from the three-dimensional volumetric scan data, and inspecting the three-dimensional representation to detect the at least one object of interest within the container. The load circuit of each input transistor includes a current source which supplies a current copied from the tail current. The particle comprising the metal and ceramic support is used as the catalyst for the production of the single-walled carbon nanotubes.
