A method for treating a nahcolite containing subsurface formation includes removing water from a saline zone in or near the formation. The lenses and systems can exhibit color fringing correction, uniform imager illumination, athermalization, and component articulation for improved imaging. The data are transmitted from the test medium to a test device, which tests the sensor in dependence on the transmitted data. % of one or a plurality of monofunctional acrylates;e) 0. Control can be in real time, or the sound or saliency signal can be recorded with an image signal for subsequent control of the latter.
