A system and machine-implemented method for deleting an electronic correspondence stored on a server is provided. Particularly, the coexistence of proprietary e verification components in an open verification methodology framework is provided. Additional fly ash materials may be similarly compared and blended. The method also includes the steps of determining if the mesh model for each of the selected component parts meets a predetermined mesh quality condition using a best practice mesh quality checking software program. 1 percent to approximately 10 percent by dry weight of said composition, said Class 2 member contributing approximately 1 percent to approximately 10 percent by dry weight of said composition, and said Class 3 member contributing an amount up to a balance by dry weight of said composition. By inputting starting point coordinates and ending point coordinates of individual image blocks contained in the image, an image block arrangement table is created.
