I am not putting any restrictions on this PPT. But, it will be very great, if you acknowledge my work. It will cost nothing. And, of course you can appreciate my work :) .Surprisingly, it also costs NOTHING. Happy to help you :)
I tried to acknowledge everything ,(not usually cut,copy and paste and then forgetting..) that helped me to make this ppt. May be why I ended up with a job in a research co. because of this.
