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.
For optimum magnetic coupling, the distance between the magnetic poles of the drive magnet and the length of the stirring. bar should be equal. Bars too long or too short in proportion to the drive magnet will not have. optimum coupling which is important to reduce spinout.
