An efficient method is disclosed for creating different field oxide profiles in a local oxidation of silicon process. The polyester composition comprises a polyester and a purine derivative. During use, the end regions are urged together and a marshmallow is impaled upon the ends. The seismic data point is mapped from an input travel time to a projected travel time. A wicking wire may be positioned in the lumen extending from the orifice, the wire having a smaller diameter than the lumen resists wetting of the exterior of the nozzle tip by fluid being dispensed by the orifice. An angle of the selected additional cluster spine is changed when the most similar cluster spine and the selected additional cluster spine exceed a maximum line segment.
