Statistical Properties of Short n-mers Located in the One Mismatch Area of Microbial Genomes.

The apparatus produces heat-shrinkable plastic caps having a metal containing top, and is comprised of: (a) at least one mandrel having a flat end-face, (b) means for placing a metal containing disc coated with heat sensitive adhesive on the end-face of said mandrel, (c) means for placing a band of preselected length of heat-shrinkable plastic over said mandrel, (d) heating means for pre-shrinking said plastic band to conform to the shape of said mandrel and to overlay the edge of said disc, said heat-shrinking means imparting insufficient energy to activate the adhesive on said disc, and (e) electric induction heating means for rapidly heat-sealing said disc to the portion of said band overlaying the disc by activating the heat-sensitive adhesive on said metal containing disc by the heat generated by induction in said metal.
