WebFeb 13, 2024 · Here we demonstrate the stability of the bcc phase of iron under conditions consistent with the centre of the core using ab initio molecular dynamics simulations. WebThe previous review had brought up the fact that a wrought iron fence had been installed, after approval, in 2024. It was replaced by a new steel 6’ fence that featured patterned metal mesh screens, without design review. The board was concerned that the visibility of the historic structure was now limited by the newer fence.
