With the use of high phosphorus iron ore, there is a large amount steel slag formed, which difficult to handle. How separate elemental has become key issue in secondary utilization slag. Experiments found that were distinct phosphorus-rich phases, iron-rich phases and matrix high-phosphorus cooled with furnace. In this study, effects heat treatment conditions basicity on P2O5 content, as well s...

We describe a boy who presented at 4 years of age with radiological hyperparathyroidism, osteosclerosis, and necrosis of the femoral heads. Plasma biochemistry was normal but the parathyroid hormone (PTH) level was very high. He was deaf and had an unusual facies but did not have the phenotype of Albright's hereditary osteodystrophy. Plasma and urine cyclic AMP reponses to bovine PTH were marke...

The objective of this research was to interrogate and develop a better understanding for a process to achieve post-anoxic denitrification without exogenous carbon augmentation within enhanced biological phosphorus removal (EBPR). Sequencing batch reactors fed real wastewater and seeded with mixed microbial consortia were operated under variable anaerobic-aerobic-anoxic and organic carbon loadin...

Excessive chemical fertilizer application in greenhouse vegetable cultivation results environmental risks and residual nutrients the soil. Conventional plot experiments conducted one field cannot recommend reduction to farmers when nutrient levels were various among different fields. In this study, nine simultaneously fields where soils could reflect of nutrient, with two rates (100 0%) for eac...

AIM Active vitamin D (1,25-dihydroxyvitamin D₃), PTH, fibroblast growth factor-23 (FGF-23) and Klotho protein are key regulators of phosphate metabolism. Hyperphosphatemia and increased FGF-23 level in patients with end-stage renal disease are associated with increased morbidity and mortality. The relationships among key regulators of phosphate metabolism are still being investigated. FGF-23, t...
