displacement current—

Quantity related to the time rate of change of the electric field

DMBA

7,12-dimethylbenz[a]anthracene, a known carcinogenic agent

DNA—

Deoxyribonucleic acid, found primarily in the cell nucleus and forms the molecular basis for heredity and cell function

g—

equation here

Electric-field strength (V/m)


electromagnetic fields—

Coupled electric and magnetic fields

ELF—

Extremely low frequency, usually associated with frequencies of the order of 3 Hz to 3 kHz

EMF—

Electromagnetic fields


foot (ft)—

in vivo—

Meaning A in the living organism, @ as measured in animals

isotropic—

Having one or more properties that are independent of direction; independent of angle


jun—
