Although personas are fictitious, they are based on knowledge of real users. Some form of user research is conducted before they are written to ensure they represent end users rather than the opinion of the person writing the personas. Below is a sample persona for an intranet project.
Nuclear energy is usually found in nuclear power stations. Countries that have a number of operating stations include the USA, Canada, UK, France, Japan, and Russia. Some other countries have one or two stations. Strictly speaking, power is the rate of energy use â¦ . So nuclear energy of a fixed amount is released for every fission that takes place, but power depends on how many fissions occur per second.
Nuclear energy can also be released by fusion of two light elements (elements with low atomic numbers). The power that fuels the sun and the stars is nuclear fusion.In a hydrogen bomb, two isotopes of hydrogen, deuterium and tritium are fused to form a nucleus of helium and a neutron. This fusion releases 17.6 MeV of energy.Unlike nuclear fission, there is no limit on the amount of the fusion that can occur.uclear energy can also be released by fusion of two light elements (elements with low atomic numbers). The power that fuels the sun and the stars is nuclear fusion.
