This invention relates to measuring the light that is scattered from particulates in a gas or liquid. The device is addressed by X-Y encoding. A segment of the air tube is flattened from an expanded diameter to a flat diameter by bending and compression of the groove in a rolling tire footprint to force air evacuated from the flattened segment along a tube air passageway. Still further provided by the invention are methods for producing cotton plants by crossing the cotton variety 05T103 with itself or another cotton variety and plants produced by such methods.
