We supposed that type I centers are formed by the Eu3+ ions in their regular positions in the crystal lattice (D2d symmetry).
The assumption is made that type I centers are formed by the Eu3+ ions in their regular positions in the crystal lattice, while the type II centers have complex structure and consist of Eu3+ ions, Ca2+ cations, and oxygen vacancies.
Therefore, the type I centers are better excited through the matrix than type II centers, that confirms our assumptions about relation of the type I centers with the Eu3+ ions in the regular positions in the crystal lattice.

As for my team of non-major-leaguers, after three consecutive losses, I started keeping them in slightly more regular positions.
The second central catheter on the left is in the regular position Open image in new window Fig. 6 Angiographic intervention for correcting the incorrect position of a central catheter in a 74-year-old male patient.
The only thing he worries about now is becoming reacclimated in his regular position against the tight end and in taking on the run.
In the concerto he had the soloist in the regular position, on stage, together with most of the strings, flanked on either side by brass groups, one with a percussionist and the other with a synthesizer player.
On the iPhone 6, it simply makes things more convenient, as I've found no difficulty in using the device one-handed even with the screen in its regular position.
Those players often play at their regular positions in preseason games, meaning they take few practice snaps with the coverage units.
