Perchlorate Selectivity of Anion Exchange Resins as Evaluated Using Ion-Selective Electrodes.

The selectivity coefficients reported for perchlorate of the high selectivity on anion exchange resins (AXRs) have not been consistent with one another. Possible errors by the unique use of four parameters (concentrations of two anions in two phases) were experimentally verified. The concentrations of perchlorate buffered at low levels (10 - 10 mol L) by two forms of AXRs were successfully determined by potentiometry with a perchlorate ion-selective electrode.

Cancer articles in weekly magazines: useful media to deliver cancer information to the public?

Objective: Japanese weekly magazines, which have a circulation of over 2 700 000, play important roles in communicating with the public. They offer a wide range of information, entertainment, gossip, politics and economics, and often include articles on cancer. However, cancer articles in magazines have not been systematically analyzed.

Forecasting Japan's physician shortage in 2035 as the first full-fledged aged society.

Introduction: Japan is rapidly becoming a full-fledged aged society, and physician shortage is a significant concern. The Japanese government has increased the number of medical school enrollments since 2008, but some researchers warn that this increase could lead to physician surplus in the future. It is unknown how many physicians will be required to accommodate future healthcare needs.
