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.
A hydraulic drive is a device that uses pressurised fluid in order to drive the machinery and it is made up of many components, of which an important one is the hydraulic pump which can have a power density of up to 10 times that of an electric motor.
