The first model, called the MG Express, has been created from the MG ZR hot hatch. |

The best protectors are presumably the high-melting-point oxides, carbides, and borides of W, Mo, Nb, Ti, Zr, etc. |

In the xylem, following the application of nitrate, both the exudation rate and the concentration of the cytokinins increased, with ZR being the dominant species in the sap. |
