Drugs Used to Treat Gum Disease Antibiotic treatments can be used either in combination with surgery and other therapies, or alone, to reduce or temporarily eliminate the bacteria associated with gum disease or suppress the destruction of the tooth's attachment to the bone.
MHD is a macroscopic theory. The partial differential equations of MHD can in principle be derived from Boltzmann's equation assuming space and time scales to be larger than all inherent scale-lengths such as the Debye length or the gyro-radii of the charged particles.
An induction or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.hereas a synchronous motor's rotor turns at the same rate as the stator field, an induction motor's rotor rotates at a slower speed than the stator field. The induction motor stator's magnetic field is therefore changing or rotating relative to the rotor.
