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 produced in the bone marrow. As they mature, white blood cells are continually released into the bloodstream. White blood cells circulate throughout the body, ready to fight infections. They live about two or three weeks, when they are broken down and recycled by the body. A normal white blood cell count is between about 4,500 and 10,000 cells per microliter. Many conditions can cause a low white blood cell count: â¢ Infection (which usually increases the white blood cell count, but may decrease it). â¢ Drugs, especially chemotherapy.
