to evaluate the correlations of the serum concentrations of trace elements with lipids and lipoproteins in water buffalo (bubalus bubalis), the serum concentrations of cholesterol, triglyceride, total lipids, very low density lipoproteins (vldl-cholesterol), low density lipoproteins (ldl-cholesterol) and high density lipoproteins (hdl-cholesterol) and their correlations with serum concentration...

A method is proposed to determine trace rare earth impurities in high-purity CeO2 by HPLC combined with electrothermal vaporization inductively coupled plasma atomic emission spectrometry (ETV-ICP-AES). The chromatographic retention behaviours of the matrix (Ce) and rare earth impurities were studied using 2ethylhexyl hydrogen 2-ethylhexylphosphonate (P507) resin as the stationary phase and dil...

Mafic enclaves from three plutons in the Chilliwack batholith have been compared with contemporaneous mafic stocks in order to determine (1) the processes by which mafic and felsic magmas hybridize in the plutonic environment and (2) whether analysis of early-formed enclave minerals, particularly apatite, can provide a means of seeing through hybridization effects and deciphering the original t...

Newly determined ilmenite-melt and orthopyroxene-melt partition coefficients are used to construct quantitative forward models of the evolution of high field strength element (HFSE, Zr, Nb, Hf, Ta, Th, U) and rare earth element (REE: Nd, Sm, Lu) concentrations during crystallisation and subsequent remelting of the Lunar Magma Ocean (LMO). Crystallisation models suggest that the initial LMO must...

The distribution of some rare earth elements (La, Ce, Sc, and Y) in the sediment samples, collected form 56 stations in the offshore of the Persian Gulf during the Persian Gulf and Gulf of Oman Oceanographic Cruise (PGGOOS) in 2012, was studied. The elements were determined by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The result revealed that the concentration of Ce (82 µg g-1) was...

the pyroxene composition of basaltic rocks from the coloured series and exotic blocks in the neyriz area are discussed. comparison has been made with equivalent rocks from oman. the clinopyroxene compositions are in cognation with trace and rare-earth element analyses which definately confirm the occurrence of three different trends in basic lavas: i-depleted tholeiite, 2-transitional basalt, 3...
