Dear Dr. Marc
Sorry to inform you that the poster has not put in any work in designing this PPT.
As rightly pointed out by others, this PPT has been posted many times (under different headings) in this site itself.
The last posting was just less than a month back.
Dear RKJain
Please don't repeat PPT's posted earlier.
With new posts, members expect new materials.
If you can not CREATE one, then post new PPT's and acknowledge the source.
Regards.
