2. A reference to or constituting the nucleus of a cell.
3. Constituting or like a nucleus: "Annexation of the suburban fringe by the nuclear metropolis."
4. Deriving destructive energy from the release of atomic energy.
2. A type of electron paramagnetic resonance spectroscopy permitting greatly enhanced resolution, in which a material is simultaneously irradiated at one of its frequencies and by a second oscillatory field during which its frequency is swept over the range of nuclear frequencies.
2. In biology, the spontaneous division of a cell or organism into new cells or organisms; especially, as a mode of reproduction; cell division.
3. In physics, the disintegration of the nucleus of a heavy atom, leading to the formation of nuclei of more stable atoms and the release of energy.
2. The clear, usually nonstaining, fluid substance of a cell nucleus.
It consists primarily of proteinacous, colloidal material in which the nucleolus, chromatin, linin (threadlike), and various submicroscopic particles are dispersed.
Nuclear fusion is the system which keeps stars, like the Sun, luminous for billions of years.
In general, nuclear fusion involves the "fusing" together of atomic nuclei of low mass to form heavier nuclei. A vast amount of energy is released in the process.

closure:
"Seven nuclear power plants in Germany that were shut down after the Fukushima disaster in Japan are likely to be closed permanently afte a decision by state environment ministers."
"A government agency warned, however, that without the seven plants Germany could have trouble coping with a failure in some part of the national power grid."
