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.

Plantar Response. Test the plantar response by scraping an object across the sole of the foot beginning from the heel, moving forward toward the small toe, and then arcing medially toward the big toe.The normal response is downward contraction of the toes.The abnormal response, called Babinski's sign, is characterized by an upgoing big toe and fanning outward of the other toes. In some patients the toes are silent, moving neither up nor down.If the toes are downgoing on one side and silent on the other, the silent side is considered abnormal.lantar Response.
