â¢ Humoral immunity is mediated by B-cells while cell-mediated immunity is mediated by T-cells. â¢ In the humoral immunity, the B-cells secrete antibodies whereas in the cell-mediated immunity, the T-cells do not secrete receptors. T-cell receptors are bound to the T-cells and the cells themselves bind with antigens.
The M.P.D. as it appears in-game. The M.P.D. is a pyramid-shaped Vril machine, with a circular indented interface at the front that, when the Vril Generator is applied, grants the power to control the Aether's energy. When powered by souIs, it is able to open a direct portal to the Aether, which drove Richtofen insane and give him Schizophrenia.
A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.Frequency (or hertz) is directly related to the motorâs speed (RPMs). In other words, the faster the frequency, the faster the RPMs go.ther names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.
