n a phase of the leukemic state marked by proliferation of leukocytes within the blood-forming tissues but without an increase in the white blood cell count: relatively few precursor cells are found in the blood smear until the phase passes and the blood becomes flooded with white cells.
energy. power that may be translated into motion, overcoming resistance, or effecting physical change; the ability to do work. Energy assumes several forms; it may be thermal (in the form of heat), electrical, mechanical, chemical, radiant or kinetic. In doing work, the energy is changed from one form to another or to several forms. In these changes some of the energy is 'lost' in the sense that it cannot be recaptured and used again.
Energy is the capacity to do work and transfer heat. Work is performed when an object or substance is moved over some distance. Energy is needed to carry out processes, such as boiling water or burning candles. Energy is also the heat that flows from a hot object or substance to a cold one, when they come in contact.
