A reaction chamber assembly for thin film deposition processes or the like includes an outer wall assembly for enclosing an outer volume and a removable liner installed into the outer volume through an outer aperture for preventing precursors or reactants from coming into contact with internal surfaces of the outer wall assembly and forming thin film layers thereon. The disruptive energy field may, in one example, include magnetic andor radio frequency fields generated by an MRI scanner. Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. The selection procedure is sufficiently simple to allow a user to memorise the steps needed in order to select a specific character. The antifreeze composition also includes other anti-corrosive additive, for example, molybdate, nitrite, nitrate silicate azoles and a variety of buffer agents.
