`  : Hi Dan, thanks for providing this article, but the copyright is problematic.  Putting aside the issue that I have no means of verifying that you are who you claim to be, the book from which the material is copied has a clear copyright statement claiming copyright by the publisher, Elsevier.  See Wikipedia:Donating copyrighted materials, but I don't see how you can donate material for which you have already given the rights to a publisher.  I agree that the article is now not so useful, but we cannot allow copyrighted material to remain on this site.  Leaving anything there at all was a compromise, my first reaction was to delete the article altogether, since extracting the non copyvio material is next to impossible without a complete rewrite from scratch.  `
