Phosphate and environmental samples were collected from Abu Tartor phosphate mine and the surrounding region. The activity concentration of 226Ra (238U) series, 232Th series and 40K were measured using a gamma-ray spectrometer. The activities of uranium isotopes (238U, 235U and 234U) and 210Pb were measured using an alpha spectrometer and a low-background proportional gas counting system, respe...

Sedimentary phosphate rocks are characteristically rich in organic matter, and contain sulfides a high concentration of trace elements, including cadmium (Cd), which is harmful to the human body. The mining rock phosphogypsum at Qingping has expanded release Cd into groundwater farmland soil. To prevent control pollution it critical reveal carrier mineral phase(s) migration mechanism other elem...

We have characterized the types of encrustations that form on ureteral stents. The deposit generates blocks is composed hydroxyapatite/magnesium ammonium phosphate (44%). Calcium oxalate dihydrate was also detected at a high degree encrustation (13%). Hydroxyapatite deposits, (13%) are generated due to their formation as consequence persistently urinary pH values. large uric acid deposits (31%)...

BACKGROUND Calcium nephrolithiasis is a multifactorial disease with a polygenic milieu. Association studies identified genetic polymorphisms potentially implicated in the pathogenesis of calcium nephrolithiasis. The present article reviews the mechanisms of calcium stone formation and the potential contribution of gene polymorphisms to lithogenic mechanisms. SUMMARY Endoscopy observations sug...

The structures and chemical compositions of valve calcific deposits were investigated. The deposits was chosen arbitrarily and subjected to chemical analysis, observation with scanning microscope, semi-quantitative determination of Ca, Mg, Na, K, P and C elements by energy dispersive X-ray, X-ray diffraction and Fourier transform infra-red spectroscopy carried out. These deposits were found to ...

A series of sites were established on Hawaiian volcanic deposits ranging from about 18 to 300 years old. Three sites occurred in areas that supported tropical rain forests; the remaining sites were in areas that supported little or no plant growth. Sites >26 years old consumed atmospheric CO and hydrogen at rates ranging from about 0.2 to 5 mg of CO m(-2) day(-1) and 0.1 to 4 mg of H(2) m(-2) d...
