A method for increasing the permeability of a subterranean formation is disclosed in which an amount of an aqueous mixture, sufficient to increase the permeability of the formation, comprising specified aminopolycarboxylic anionic species, and specified cationic species, is injected into the formation matrix. According to an embodiment, a semiconductor substrate is provided comprising a readout circuit. The upper material covers conductive islands in a substrate. One end of the rod is connected to a protrusion offset from the axis of a gear connected to the output shaft on the motor. Objects to be estimated are classified into a total of 12 kinds, such as a \u201cman, woman, child, bike, unknown, dog\u201d and a \u201cright, left\u201d.
