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.
Definition. High white blood cell count is an increase in disease-fighting cells (leukocytes) circulating in your blood. High white blood cell count is also called leukocytosis. The threshold for high white blood cell count varies from one medical practice to another.
A low white blood cell count can be related to a number of causes, including viral infections, cancer and diminished immune system function, according to MayoClinic. Detailed blood screening is the first step necessary to determine the specific cause. A low white blood cell count is called leukopenia. Leukopenia is best defined as a decrease in the number of white blood cells, called leukocytes, in the blood. The test that determines blood cell count is the white blood cell (WBC) test, which is often included as one part of the complete blood count (CBC) test.
