 The crystal structure of two B-type carbonated apatite samples was re-analyzed, using the data of Wilson et al (2006). By applying the least squares method for the determination of carbon and oxygen atoms, a slightly different result was obtained, suggesting that the carbonate ion is not rigorously planar. Keywords Carbonated apatite, Carbonate, Xray diffraction.

Consumers are so much conscious and sensitive in case of selecting brand. This study investigates a comparative the influence advertising on brand performance carbonated soft drinks. If there is one requirement to provide businesses competitive edge this highly times, it necessity for efficient effective advertising. Since money spent advertising, analyzing its effects still essential businesse...

A double-blind comparison of carbonated bupivacaine and bupivacaine hydrochloride in extradural anaesthesia was performed in 40 patients. No significant differences in the onset times, sensory blockade, motor blockade and duration of anaesthesia were demonstrated. Carbonated bupivacaine does not appear to offer any advantage over the hydrochloride salt for extradural anaesthesia.

Naturally occurring carbonated mineral waters have been known for a long time. These effervescent waters exist as a consequence of excess carbon dioxide in an aquifer dissolving under pressure. Although claims for the medicinal properties of these mineral waters have been grossly exaggerated, the presence of carbon dioxide does make aerated waters and soft drinks both more palatable and visuall...

ultramafic rocks are essentially constituted by silicates of magnesium: forsterite, and/or diopside-enstatite; who’s the most common hydrothermal alteration are the serpentinization. to bou azzer, the serpentinisation affected almost all of the ultrabasic rocks. among the phenomena bound to the serpentinisation observed on the ground, we distinguish the magnesium deposits (carbonated serpentini...
