First developed by the United States in the early 1950s, the hydrogen or thermonuclear bomb is perhaps a thousand times more powerful than a uranium-or plutonium-based fission bomb, making it effectively the nuclear weapon's nuclear weapon.n a fusion reaction, two atoms of the lightest element, hydrogen, fuse to create one atom of helium, the next-lightest element â and release much more energy.
Clival tumors were found to enhance intensely. A clivus of very low signal intensity (signal void) on T1- or T2-weighted images was always abnormal. The clivus with marrow reconversion was uniformly hypointense relative to the pons on T1-weighted images and isointense relative to normal marrow on T2-weighted images.
Rhonchal fremitus, also known as bronchial fremitus, is a palpable vibration produced during breathing caused by partial airway obstruction. The obstruction can be due to mucus or other secretions in the airway, bronchial hyperreactivity, or tumors.epatic fremitus is a vibration felt over the patient's liver. It is thought to be caused by a severely inflamed and necrotic liver rubbing up against the peritoneum. The name 'Monash sign' has been suggested for this clinical sign, after the Monash Medical Centre in Melbourne, Australia.
