ACKNOWLEDGEMENT

First of all I would like to thank almighty GOD who has given this wonderful gift of life

to us. He is the one who is guiding us in right direction to follow noble path of humanity.

In my Four weeks industrial training it is a wonderful experience to be a part of it where

I have opportunity to work under brilliant minds. I owe my deep regards for the

supporting and kind staff authorities who are helping me in my lean patches during these

Four weeks. The knowledge I am gaining throughout my studies have the practical
