Gary McKinnon. Gary McKinnon was known by his Internet handle, âSolo.â Using that name, he coordinated what would become the largest military computer hack of all time. The allegations are that he, over a 13-month period from February 2001 to March 2002, illegally gained access to 97 computers belonging to the U.S. Armed Forces and NASA.
The atrioventricular valves of the heart are important in preventing backflow. The mitral valve prevents backflow into the left atrium, and the tricuspid valve prevents backfl â¦ ow into the right atrium.
The right ventricle pumps the blood to the lungs through another valve, called the pulmonary semilunar valve, and then it returns to the left atrium. The blood flows through the bicuspid valve into the left ventricle. Again, when all the blood is in the left ventricle, the bicuspid valve slams shut to prevent blood from flowing backwards.
