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.
White blood cells are manufactured in bone marrow â the spongy tissue inside some of your larger bones. A low white blood cell count usually is caused by: 1  Viral infections that temporarily disrupt the work of bone marrow.  Certain disorders present at birth (congenital) that involve diminished bone marrow function.
