The distribution of yttrium
in rats has been determined and showed that it can be severely accumulated in stomach, lungs, kidney, spleen, and thighbone as time goes on (these data are published in Chinese) .
Isovalent isomorphism of holmium ([Ho.sup.3+]) and yttrium
([Y.sup.3+]) in oil and gas-bearing deposits, is most likely conditioned upon the thermodynamic conditions and the properties of Y and Ho, how strongly--the positive elements (cations) are to form complex compounds with negative anions of oil and gas hydrocarbons.

Zinc nitrate (Zn[(N[O.sub.3]).sub.2] x 6[H.sub.2]O), yttrium
nitrate Y[(N[O.sub.3]).sub.3]-6[H.sub.2]O, sodium sulphide ([Na.sub.2]S x 9[H.sub.2]O), EDTA-ethylenediamine, and all chemicals used in this work were of AR grade and used as received without further purification.

There is also potential to extend the Yttrium
zone to the West and South West where drilling to date has been very wide spaced (400 x 400 metres and 800 x 400 metres).
In experiments using cloned calcium ion channels in embryonic kidney cells, the researchers found that nickel and yttrium
, two metal catalysts used to form the single-walled carbon nanotubes, were interfering with the ion channel's ability to absorb the calcium.
and iridium plugs are more expensive than traditional plugs, but the coatings provide much better wear resistance and maintain their gap longer.
His efforts advanced the yttrium
barium copper oxide-coated conductor.
For producing condensed electric contact materials copper, molybdenum, and alloying elements (yttrium
and zirconium) were used as initial elements.
The Asian behemoth now supplies approximately 95 percent of the world's consumption of "rare earths," such as cerium, neodymium, lathanum, yttrium
, and dysprosium.
