Abstract: A surf disc has a planar bottom surface and parallel top surface with an upwardly extending hemispherical dome. An annular thumb recess is formed in the top surface and a frusto-conical rocker is formed in the bottom surface.

Abstract: This invention relates to immunogenic compositions capable of potentiality growth hormone activity, comprising an immunologically effective amount of a composite peptide comprising at least two non-contiguous somatotropin epitope amino acid sequences, wherein said composite peptide is substantially free of receptor binding domain sequences; and an immunologically acceptable excipient. The invention further relates to methods of using an immunogenic composition of the invention to potentiate the action of growth hormone in pigs.

Abstract: Polyolefin-substituted dicarboxylic ester derivatives, having an ester group derived from a polyether polyol and process for making such; wherein the ester derivatives are useful additives in lubricating oil compositions and concentrates thereof.
