The kinetics of tantalum nitridation is charaterised by two stages. In a first stage, the formation of Î²-TaN 0.05 species leads to a strong attenuation of the metallic tantalum signal. During the second stage, Î²-TaN 0.05 transforms into Î³-Ta 2 N and cubic/hexagonal TaN species.
The Grangerson Sheperson feud is symbolic of the civil war. The Shepersons would represent the north and the Grangerfords would represent the south. In the novel the Shepersons win. This is similar because this is the exact outsome of the civil war.
The feud between the Grangerfords and the Shepardsons can relate to how slavery collapsed and southern culture itself. Between the two families there was a lot of back and forth fighting. With slavery there was a lot of the same things.
