Assessing sulfate concentration levels and their distributions within road alignments is crucial for the design of highway projects. Sulfate minerals in soils react with calcium-based additives, leading to sulfate-induced heaving pavement failures. However, a reasonable assessment extent using current practices, such as conventional laboratory-based methods, still challenging because spatial he...

Seventeen water-soluble substances (of sodium, ammonium, potassium, magnesium, calcium, formate, methanesulfonate, glyoxylate, chloride, nitrite, nitrate, glutarate, succinate, malate, malonate, sulfate and oxalate) in 94 samples of particle matter the ambient air, collected over ten months, a suburb Belgrade (Serbia), were determined by ion chromatography. To apportion sources air pollution, l...

PURPOSE Calcium oxalate urolithiasis is one of the most common urinary tract diseases and is of high prevalence. The present study proposes to evaluate the antilithiatic property of hydrogen sulfide and its metabolites like thiosulfate & sulfate in an in vitro model. MATERIALS AND METHODS The antilithiatic activity of sodium hydrogen sulfide (NaSH), sodium thiosulfate (Na(2)S(2)O(3)) and sodi...

Dairy products provide abundant, accessible calcium for humans, while some calcium sulfate-rich mineral waters could provide appreciable amounts of calcium. But there is little evidence that this calcium is as available as milk calcium for making bone. The availability of calcium was studied by monitoring bone parameters in 2-month-old pigs fed restricted amounts of calcium (70% RDA) for 2.5 mo...

Although the use of calcium sulfate has been used as a bone graft substitute in the treatment of fractures for more than a century, few studies investigate the use of recently developed injectable calcium sulfate-based bone graft substitute with high compressive strength after curing in situ. In this study, we evaluated preliminary results of a high compressive strength calcium sulfate-based bo...
