Iowe the biggest debt to my family. I’d like to thank my dear supportive wife Behnaz, my gozal
daughter Maral, and my son Yaseen, who all had to put up with many lost family evenings and
weekends. Without their love and support I could never have finished this book.
I thank my parents (Monireh and Bagher Parsian) for their unlimited support. Also, I thank
my dear sister, Nayer Azam Parsian, and my dear brother, Dr. Ahmad Parsian, for their support
and just being there for me....
