The present invention provides an organicinorganic compositive dispersant and a method for producing the same. One system embodiment includes a seismic streamer including a plurality of receivers, a skew detector adapted to detect inline skew of the streamer, and a receiver selector adapted to select which receivers in the streamer to use in data acquisition based on the detected streamer inline skew. The guide rollers are individually mounted, and, at an exit of the decollating section, are rotatably disposed jointly with transfer rollers of an adjoining transfer region, which are driven independently of the conveyor belts on a common guide axle. The AlOx tunnel barrier has improved uniformity of about 2% across a 6 inch wafer and can be formed from an Al layer as thin as 5 Angstroms. Upon submission of the new tag, a librarian approves the tag before storing and placing the tag in the hierarchical tag database.
