Grossular is a secondary mineral commonly observed in Al-lende CAIs associated with monticellite, wollastonite, forsterite, anorthite, and wadalite [1–6]. Studies of the 26 Al– 26 Mg systemat-ics in grossular yield (26 Al/ 27 Al) 0 ranging from ~5×10 –5 to <3×10 –6 suggesting grossular formation started almost contempo-raneously with crystallization of CAIs and lasted > 3 My [1–3]. This interpr...

I n t r o d u c t i o n THE structures of the cancrinite-group minerals are character ized by parallel s ix-membered rings consisting of alternating A104 and SiO4 tetrahedra. The hexagonal symmetry is the result of the stacking of such six-membered rings in an AB... sequence. This stacking leads to large continuous channels that are formed by twelve-membered rings of alternating A1Oa and SiO4 t...

Ba20Hg103, the next Hg-rich binary barium mercuride after BaHg11 and BaHg6, was synthesized from melts of the elements, which were slowly cooled from 550 to 200 ◦C. It forms a new complex cubic structure type (F4̄3m, a = 2333.30(10) pm, Z = 4, R1 = 0.0651) with four Ba und 13 Hg positions as determined by means of single-crystal X-ray diffraction. The structure can be best described by decomposi...

the aim of our work was to compare cytotoxic and membrane-damaging effects of o. majorana l. essential oil and linalool on hep g2 and to investigate their possible protective (antioxidant) effects against h2o2 induced membrane damage. the oils were investigated by gc and gc-ms and antioxidant activity was evaluated by dpph and -carotene–linoleic acid assays. assessment of cell viability was ma...

background: the purpose of this study was to investigate the efficiency of flat sheet membrane bioreactor (fs-mbr) in bod 5 and cod removal of isfahan south municipal wastewater treatment plant. methods: in this study a submerged fs-mbr, with 140 liters volume was fed using microfiltration membrane (mf) during 109 days and hydraulic retention time of 20 hours. findings: the mbr application in m...
