Studies in humans, cats and dogs have all substantiated positive weight loss results when adding fiber to calorie restricted programs. Canned green beans provide extra fiber, are generally a hit with dogs, and only contain about 50 calories per can. Human subjects report a greater sense of satiation or âfullnessâ with the fiber addition and tend to eat less if given free access to food.
1 Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.  Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule.
When an atom splits into two parts, either through natural decay or when instigated within a lab, it releases energy. This process is known as fission. It has great potential as a source of power, but is also has a number of safety, environmental, and political concerns attached to it that can hinder its use. Fission definition. An atom contains protons and neutrons in its central nucleus.
