Hello Everyone, The first few minutes of the Lecture was not recorded, This is because the Professor started the lecture Via Skype and i was told to wait, it was supposed to be a brief introduction by the professor but he decided to go along with lecture, then i was told to start recording. The clip is split into two parts and the first part involves the lecture with the professor and the other part a group discussion. I am sorry for any incovinience this may have caused you. Thanks for your Understanding
