Robust calibration models were determined for iron, aluminum, silicon and potassium, whilst the results for manganese were encouraging. Phosphorous, present at low levels in the ores measured, remained the most difficult element to determine accurately. The combination of LIBS and PCR shows potential ...
En humanos los niveles plasmáticos de renina normalmente son menores de <1 pmol/L mientras los de prorenina usualmente son 10 veces mayores (Campbell 2008). En ciertos fluidos compartimentalizados como el humor vítreo de pacientes diabéticos portadores de retinopatía proliferativa, pueden...

However, for large contents the problem of increasing the accuracy of spectral methods becomes very difficuh: many of the methods are based on the study of a narrow range of materials (for example, iron ores [1, 2], clays [3-9], limestones [10], magnesites [11, 12], etc.) and ...
(English):The lateritic weathering crusts of the northeast of Cuba constitute sources of obtaining Ni. The relationship of this metal with the mineral phases of iron (goethite specifically) in the oxidized ores of the nickeliferous crusts has been revealed by diverse investigations ground in ...
More recently, the Tula’ergen Cu–Ni deposit was found at the eastern end of the Huangshan–Jing’erquan ore belt and the Hongling deposit was identified at the western end of this ore belt. Re–Os dating of sulphide ores and SHRIMP zircon U–Pb dating of related mineralized mafic ...
