A capsule formulation of pirfenidone is provided that includes pharmaceutically acceptable excipients. Columnar spacers are formed on the counter substrate. An exothermically reactive structure is disposed on the controlling mechanism, such that, when activated, an exothermic alloying reaction between alloys in the exothermically reactive structure operates the controlling mechanism. The particles may be described as contiguous pixels of the same color, and the particle information may relate to the size and quantity of the particles of each color. a blood pump, said pump having a rotor for the forwarding of the liquid from the inlet of the pump to the outlet, the rotor is used for the determination of the viscosity.
