Moreover, they distort real costs of ageing considerably. This creates mirage drives fiscal policy in wrong direction like will-o’-the-wisp. The demographic change systematically overestimated.

Single crystals of GdCa4O(BO3)3 were examined to determine their thermal properties. Samples were grown by the Czochralski pulling technique. There were three types of samples: a pure crystal, the crystal doped with neodymium (4 at.% of Nd), and the third one doped with ytterbium (7 at.% of Yb). All samples were rectangular prisms with edges parallel to the axes of the optical indicatrix X, Y ,...

There are many factors needed, other than the causative organism, to effect an epidemic.
