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.
Magnetic storage. Longitudinal recording and perpendicular recording, two types of writing heads on a hard disk. Magnetic storage or magnetic recording is the storage of data on a magnetised medium. Magnetic storage uses different patterns of magnetisation in a magnetisable material to store data and is a form of non-volatile memory.
