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.
In a DC motor, the magnet (and its magnetic field) is fixed in place and forms the outside, static part of the motor (the stator), while a coil of wire carrying the electric current forms the rotating part of the motor (the rotor).
