What specifically are you trying to find out about adverse yaw, I will be able to easily assist you with this.
However, in a nutshell, it is caused by the fact that during a turn one aileron is deflected up and thus in a low pressure area and the other is deflected down and therefore in a high pressure area, as more drag is produced in the high pressure area it thus slows that wing down causing the aircraft to yaw in the opposite direction of the turn. There are 2 ways to combat this, either by differential (or Frise) ailerons, or, by positive and coordinated use of the rudder, or, a combo of the 2.
