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 (WBC) count is a decreased number of white blood cells (leukocytes) in the blood. A low WBC count is referred to medically as leukopenia.utoimmune diseases that attack your white blood cells can also lead to a low WBC count. Several different prescribed drugs, including chemotherapy, are known to decrease WBC production or destroy WBCs. A low WBC count can be serious because it increases your risk of developing a potentially life-threatening infection.
