Department of Physics, Chemistry and Biology (IFM)

I am very much grateful to my supervisor professor Bo Ebenman, for his help and invaluable guidelines during this study. He has been a great source of inspiration for me.

I would  like to express my sincere gratitude to Alva Curtsdotter and David Gilljam for their motivation and proper guidance throughout this study period. I could not have done this thesis without their help.

Likewise, I would like to thank my family who has been a constant source of support and motivation for me.

Thanks to the people of the biology department for providing me friendly and supportive environment during this study.
