Acid mine drainage (AMD) is the outflow of acidic water from metal mines or coal mines. When exposed to air and water, metal sulfides from the deposits of the mines are oxidized and produce acid, metal ions and sulfate, which lower the pH…
Very important research, with both theoretical and experimental results in the advancement of physical models that explain the MR effect, try to keep the MRF formulation as simple as possible, usually with only two components: a magnetic…
