The running back was on the field for 61 percent of the offensive plays, with Tyler Allgier at 35 percent and Cordarrelle Patterson at 13 percent. Plus, Smith noted, Robinson's presence in and of itself can be a factor for the offense. "Sometimes, his impact away from the ball can open things up," Smith said in his press conference.

mechanical ball milling is more thermally stable. Furthermore, the dramatic weight loss after 230 °C shows the significant loss of PEI. This is mainly due to the decomposition of the amino group. In summary, the TGA results show the good thermal stability of ballmilled adsorbents. The FTIR spectra of the adsorbents are shown in Figure 5.

M S values of the annealed ribbons and ball milled powders are shown in Fig. ribbon samples show a clear peak of 79 emu g −1 at the nominal composition of Mn 52 Bi 48. On average, the magnetization of the samples drop 4% after milling for 8 h. The cause for the drop in magnetization is primarily due to the decomposition of LTPMnBi into elemental Mn and Bi which is discussed below.
