wow , it's really an interesting group to join especially that I'm compiling my degree book right now ...ohh the THESIS ...I did not really realize that the AUTHOR job is such a HARD JOB until I started on my thesis , any way , although it's a hard job but really interesting and exciting too cause it's always INNOVATIVE and makes your mind WORKING to get out with thoughts and perspectives to put in your thesis like those I am PUTTING RIGHT NOW. Any way I hope the 1st. book published in this group will be my booky-thesis....HAHAHA..Thanks every one and have a great working day..Mohsen
