Though most manufacturers have stayed true to the dual-clutch pattern (two gear splines and two clutches), BMW chose a seven-speed single-clutch version for its mid-2000s M5 super-sedan, while supercar-maker Lamborghini also went with the single-clutch gearbox for its Aventador.
Definition. Meckelâs diverticulum is the most common problem that occurs in the digestive system. This condition happens when a pouch of tissue forms on the wall of the lower part of your small intestine (also known as your bowel).
Symptoms. Most people with Meckel's diverticulum do not experience any symptoms. Symptoms occur only if the diverticulum bleeds, becomes infected or causes an obstruction. These symptoms generally occur during the first few years of life, although they may not appear until adulthood. The bleeding, even when severe, is usually painless.
