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 is derived from uranium, a radioactive element. When the nucleus of an atom of U-235, an isotope of uranium, is split by a neutron, it releases heat and other neutrons.ome countries such as Sweden and Russia also use the heat generated from nuclear fission to directly heat homes and buildings. Nuclear energy has other applications as well: 200 smaller nuclear reactors power 150 ships worldwide, including nuclear submarines, icebreakers and aircraft carriers.
