Fission weapons Nuclear weapons exploit two principle physical, or more specifically nuclear, properties of certain substances: fission and fusion. Fission is possible in a number of heavy elements, but in weapons it is principally confined to what is termed slow neutron fission in just two particular isotopes: 235U and 239Pu. These are termed fissile, and are the source of energy in atomic weapons.
An explosive chain reaction can be started with relatively slight energy input (so-called slow neutrons) in such material. An actual 239Pu ingot, alloyed with gallium for improved physical properties Isotopes are 'varieties' of an element which differ only in their number of neutrons. The Importance of Project Management. Project management as a management discipline underpins much economic activity.
In industries as diverse as pharmaceuticals, software and aerospace, projects drive business. And in the public sector, it is effective project management that translates politicians' promises of new roads, schools and hospitals into gleaming new constructions that improve everyday life. So you'd imagine that it would be possible to place some sort of figure on the importance of project management to the UK economy. How much GDP does it drive? In which sectors of the economy?
