Ambient aerosol samples were collected over the northern Indian Ocean during two 1 month-long research cruises (German R/V Meteor) that took place during the intermonsoon (May) and SW monsoon (July/August) of 1995. A high volume and two small volume collectors were used to collect samples, which were subsequently analyzed for ferrous iron, 32 elements, and anions and cations. The present paper ...
در مخازن شکافدار، میزان برداشت نفت به آشام خودبخودی آب در ماتریس و خارج ساختن نفت موجود در آن به سمت شکافها، بستگی دارد. اما این فرآیند زمانی امکانپذیر است که ماتریس بلوکها، «آبتر» باشد. از آنجا که مخازن کربناته غالبا «نفتتر» میباشند، به کارگیری آشام خودبخودی در مخازن کربناته شکافدار مستلزم تغییر ترشوندگی در حین عملیات سیلابزنی میباشد. در این مقاله، تأثیر یونهای مؤثر بر پتانسیل سطح (...
Introduction: Several lunar highland meteorites were found in the Dhofar region of Oman. Here we report the first data on the petrography and mineralogy of four new lunar stones, Dhofar 304, 305, 306 and 307. Dh-304 was found close to Dh-025 and 301, whereas Dh-305, 306 and 307 were recovered nearby Dh-081, 280, 302 and 303. The new meteorites are moderately weathered, impact-melt breccias. No ...

Inorganic sulphate and silicate is required by all mammalian cells to function properly, it the most abundant anion in human plasma. Sulphate ions are major source of sulphur which considered an important element for sustenance life as present essential amino properly.This paper aimed compare constitutional physical property pure hydroxyapatite (HA) doped with different kinds anions such (SO42-...
In the title compound, 2C5H12N+·SO42-·2C3H8N2S, the C=S groups of the two independent 1,3-di-methyl-urea mol-ecules and the sulfur atom of the anion lie on twofold axes. The packing is centred on bis-(piperidinium) sulfate ribbons parallel to the c axis; the cations are hydrogen bonded to the sulfate by N-H⋯O and C-H⋯O inter-actions. The 1,3-di-methyl-urea mol-ecules are also hydrogen bonded to...
