                        At the sessions, 11 Keynote Talks, many oral presentations were delivered by the distinguished scholars and colleagues from 5 continents including different countries and cultures. Also, many posters were delivered by young colleagues and participants. I had a facility to interact with the delegates and speakers via the chat conversation during the sessions. The Conference has been fruitful and beneficial with these contributions in favor of the distinguished speakers and conference committee members. Also, I enjoyed joining this important conference. Congratulations to the Conference Director and Conference Committee on their great efforts and great consideration. I am sure this important conference has been beneficial for the scholars and participants, and researchers.
