The concentrations of 22 major and trace elements in livers from rats aging from 5 to 113 weeks old were determined. The rats investigated were the same rats previously reported with respect to 29 elements in bones (femur) and 26 elements in kidneys.

Cavitation erosion has been a serious problem in the use of turbomachineries such as ship propellers. In this paper, we proposed a technique to prevent cavitation erosion using electroless nickel-phosphorus plating (ENP). ENP was plated on JIS CAC703
