The isotopic composition of mercury (Hg) was determined in cinnabar ore, mine-waste calcine (retorted ore), and leachates obtained from water leaching experiments of calcine from two large Hg mining districts in the U.S. This study is the first to report significant mass-dependent Hg isotopic fractionation between cinnabar ore and resultant calcine. Data indicate that delta202Hg values relative...

thoritc and, from the results of infra-red absorption spectra, concluded that this material contained (oH) groups; however, Mumpton and Roy (1961) in their experiments found no evidence in support of this substitution. rn the course of an extensive study of granitic pegmatites in yugoslavia, M. Risti6 and s. Pavlovi6 found in a pegmatite from prokuplje area, Serbia, zircon crystals associated w...

Improving the patient experience—or the patientcenteredness of care—is a key focus of health care organizations. With a shift to reimbursement models that reward higher patient experience scores, increased competition for market share, and cost constraints emphasizing the importance of patient loyalty, many health care organizations consider optimizing the patient experience to be a key strateg...

Abstract The Maršíkov–Schinderhübel III pegmatite in the Hrubý Jeseník Mountains, Silesian Domain, Czech Republic, is a classic example of chrysoberyl-bearing LCT granitic beryl–columbite subtype. This thin dyke, (up to 1 m thickness biotite–amphibole gneiss characterised by symmetrical internal zoning. Tabular and prismatic chrysoberyl crystals (≤3 cm) occur typically intermediate albite-rich ...
