The present disclosure provides an apparatus for treatment of mined material. 1 to 100 micrograms per kg of body weight, of a compound capable of maintaining the integrity of connective tissue, for example pentosan polysulfate. The electrons are naturally drawn to their equilibrium state and they emit light at a wavelength that depends on the type of dopant ion. For example, the first sensor can receive an authentication value associated with the subscription service from the second RFID sensor.
