The present invention provides a solid golf ball comprising a hot-molded product of a rubber composition comprising 100 parts by weight of a polybutadiene synthesized using a rare-earth catalyst and having a cis-1,4 content of at least 60% and a 1,2 vinyl content of at most 2%, having a viscosity \u03b7 at 25\xb0 C. The process includes determining one or more equations that when solved present a representation of forecasted characteristics of the target item, wherein each of the one or more equations includes one or more variables. The semiconductor device comprises a pattern formed by the resist pattern. The insert includes a weir defining an intake area for receiving an influent liquid; and a round-edged orifice positioned within the intake area. The gripping assembly includes threaded tubes surrounding a rod with opposite threads at each end for driving the tubes, whereby the gripping fingers on the gripping assembly are movable to grip the vault buss blocks. In one embodiment, a dark field trim mask can be used with the FPSM.
