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.
For example, a Victorian brooch that is decorated with ivy represents everlasting love, deep friendship or marriage, though if this brooch is also dotted with pearls it means it's a mourning piece (pearls represent tears), so it would have been worn by someone who wanted to remember a departed loved one.
