Tile crystal structures of sjogrenite and pyroaurite, two stacking modifications of approximate composition Mg.Fe.(OH),.(CO.).4H.O, have been determined by X-ray diffraction using three-dimensional methods. Sjogrenite is hexagonal, with a 3,13, C 15.66 A, space group P6.!mmc, Z = !; pyroaurite is rhombohedral, with aH 3,13, CH 23.49 A, space group R3m or R3m, Z = i. Both structures are based on...
متن کاملBacteriological Study of Urinary Stones
Background: Despite modern antibiotic therapy and technological advances in lithotripsy, the presence of infection in patients with urinary stones, as well as with infectious stones is still a significant cause of morbidity and mortality. Recent findings lend more theories as to how infection leads to stone formation. Aim: The bacteriological study of urine and stone samples from patients with ...

متن کاملA Survey on the Presence of Calcifying Nanoparticles in Renal Stones, Gallbladder Stones and Atherosclerosis Plaque
Background & Aims: Calcifying nanoparticles are different forms of calcium and phosphate in sediments. Recent evidence suggests that calcifying nanoparticles (CNPs) are probably selfreplicating. Several diseases are linked to nano-bacteria including kidney stones, gallbladder stone, cardiovascular plaques, oral–dental plaque, many cancers, and autoimmune diseases. The aim of this study was to a...
