A multi-port flow selector manifold valve includes a plurality of inlet ports adapted to be coupled to a fluid source, a test outlet adapted to communicate with at least one of the plurality of inlet ports, and a production outlet adapted to communicate with at least at least one of the plurality of inlet ports. Examples of disease changes to normal include, but are not limited to strokes, cellulitis, facial acne, precancerous lesions, nerve injury like paresthesia, periorbital hematoma, pentathol general anesthesia recovery, headaches, improved sight, hypothyroidism, dental pain, dental gingivitis, insect bites, delayed hypersensitivity states, phlebitis of veins and synergism of steroid activity. The hydrogen sulfidecarbon dioxide contaminants are thereby sequestered in the sea water utilized in the scrubber, which sea water may be further processed andor re-introduced into the deep of a body of water, where the contaminants will remain isolated for hundreds of years. The control unit is configured to cause the amplification factor to be higher than a present amplification factor, only when the output value given by the amplification unit is not saturated even where the amplification factor is caused to be higher than the present amplification factor, based on the comparison result of the comparison unit.
