Phase 5: Construction Administration. Finally, once you have selected a contractor and construction is under way, we move into the fifth phase of the architectural design process â construction administration.
The neutron is a subatomic particle, symbol n or n0 , with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Nuclear fission. In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.
