We have time for five-minute rounds of questions and answers. I encourage members to remember that the period of five minutes includes the answers, so it's always good to have a concise question.
Before we do this, however, I just want to say to Dr. Vollertsen that normally, when people present materials at committee, as they were doing today, we request that they table those materials. If our clerk could contact you after this meeting is over and arrange to get copies of those photographs, we would be very grateful. They could then go into the record of the committee.
Let's turn first to Mr. Silva.
