WebPCR method phase 1: homogeneity data On completion of each sample type preparation and its verification against the standard curves as described above, homogeneity was assessed for each sample type by analysis of ten randomly-selected units under repeatability conditions. The data are provided in Table 4. WebComparing with the homogeneous slope, the nonhomogeneous slope has more significance in practice. The main purpose of the present study is to provide a preliminary idea that how the nonhomogeneity influences the stability of slopes under four different water drawdown regimes. Two typical categories of nonhomogeneity, identified as …
