Arch Esp Urol. Fit is qualitative; it measures the degree to which an investment dovetails with a company's existing processes, capabilities, and culture. Using viability and fit to assess their online initiatives, companies can then plot these efforts onto a simple matrix, called an Internet portfolio map. Their location on the matrix will suggest whether each initiative should be invested in, redesigned, sold or spun out, or killed. In the Tat protein, only one peptide primed CD4+ T cells of eight HLA unrelated healthy donors. T cells induced by this peptide recognized immature DC loaded with the native Tat protein and are restricted by multiple HLA-DR molecules, in agreement with its binding capacity. This peptide was therefore processed in an appropriate manner and was highly immunoprevalent. The teeth were stored in 1 per cent NaCl and thymol for 3 and 12 months at 20 degrees C whereafter a standard fluorescent dye marginal leakage test was performed on 320 specimens (eight teeth per treatment). Restoration combinations were grouped into 4 seal classes depending on percentage marginal seal achieved for each combination: 0-25 per cent; 26-50 per cent; 51-75 per cent and 76-100 per cent. The 80 remaining teeth (2 teeth per treatment) were fractured to expose the restoration and cavity surface, covered with marginal seal material and this was analysed by energy dispersive X-ray analysis.
