Recent studies showed that Cl-rich hydrothermal liquids are enriched in LREE, and the Hf/Sm, Nb/La, and Th/La ratios are less than 1 while the F-rich hydrothermal liquids are simultaneously enriched in LREE and HFSE
with the Hf/Sm, Nb/La, and Th/La ratios generally larger than 1 (Oreskes and Einaudi, 1990; Bi et al., 2004; Mao et al., 2006).

In 2015, the RNHR was made up of 233 hospital-based Epidemiological Surveillance units distributed across the country, including the HFSE
and REE also decrease their concentration in amphiboles with lower Ti (Fig.

The same is true for the Nb-anomaly as well as for ratios of large-ion lithophile elements (LILE) to light rare earth elements (LREE) and LILE to high-field strength elements (HFSE
) (see  for the importance of these ratios for subduction processes).
The discussion on Internet Communication and the Ethical Implications of the Human Flesh Search Engine (HFSE
) probably started in China in 2008 when a deadly earthquake struck Sichuan province and left many people missing.
Although clay adsorption of these elements will play a role, much of the HFSE
content of natural continental desert [PM.sub.10] is contained within tiny nuggets of phosphates and Ti-oxides, and these have the potential to be extremely long-lived and recyclable (e.g.
Thus geochemical/ petrological investigations of komatiites have been based upon elements that are considered to be less mobile, including Al, Ti, high-field-strength elements (HFSE
) and rare-earth elements (REE).
The Healthcare Facilities Symposium & Expo (HFSE
) will celebrate its 20th Annual Conference & Expo on October 24, 2007, at the Navy Pier in Chicago.
