Elimination: The half-life of lanthanum
in the blood is estimated at 53 hours and the half-life in the bone may be as long as 2 to 3.6 years (Anon, 2007).
At least one metalcasting facility (a ferrous manufacturer in Wisconsin) has begun reducing the amount of cerium and lanthanum
used in its treatment alloys.
Clinical, biochemical traits were compared before and after the use of lanthanum
carbonate in patients on maintenance hemodialysis.
Development Point 3: Specific ratio of lanthanum
However, that low crystallinity for stabilized samples is less evident for LVSZT sample, when compared to LVT one, which permits to infer the lanthanum
acts to order the anatase structure.
According to the XRD spectra (Figure S1C), the solid may contain some La[(OH).sub.3], but most of the solid was complex of lanthanum
The observation with SEM using backscattered electrons allowed characterizing the distribution of lanthanum
on the surface to the fact that it is a heavier element and thus appears brighter in the image.
The LDPO was synthesized by traditional coprecipitation method of lanthanum
and iron in solution.
has been shown to have similar efficacy to calcium-based phosphate binders in terms of controlling serum phosphate, with fewer incidences of hypercalcemia (Salusky, 2006).
For the preparation of La-doped ZnO samples, lanthanum
nitrate [La[(N[O.sub.3]).sub.3].6[H.sub.2]O] was added to the initial mixture of zinc nitrate and glycine.
These 114-inch oculars incorporate a 7-element design with high-transmission lanthanum
glass and multi-coated surfaces to produce ghost-free images across the entire field.
A team of scientists have found replacements for these scare elements: a green phosphor that reduces the terbium content by 90% and eliminates lanthanum
and a red phosphor that completely replaces europium and yttrium oxide.
