hydrogen bomb. hydrogen bomb or H-bomb, weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. In an atomic bomb, uranium or plutonium is split into lighter elements that together weigh less than the original atoms, the remainder of the mass appearing as energy.nlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy.

Inflammation or injury of the plantar aponeurosis (known as plantar fasciitis) is common in athletes and will cause foot pain and may result in further leg injuries if left untreated. The condition is treated with rest, pain relievers, or in extreme cases, extracorporeal shock wave therapy. Back to Foot.uring walking, the plantar aponeurosis functions mainly during heel rise to toe off..
