background: the effective size of the end grain of horizontal roughing filters (hrfs) is larger than 2 mm. this study aimed to examine the efficiency of hrfs in removing nitrate, phosphate, and chemical oxygen demand (cod) from effluent of a wastewater stabilization pond. methods: this experimental study was conducted in 2013. the pilot project was transferred to the karaj wastewater treatment ...

background & aims of the study: detergent and phosphate are one of the main and vital threats (eutrophication phenomenon and production of synthetic foam) for the source of drinking water, agriculture and industrial uses in the ahvaz, iran that threaten human health. the aim of this study is the evaluation of the efficiency of the electrocoagulation (ec) process in the removal of detergent and ...

This experiment was lay out in order to evaluate the effects of different biofertilizers on seed yield, protein and oil of rapeseed in Iran. The experiment was a factorial design with three replications. Treatments were four nitrogen biofrtilizers (control (N1), Nitroksin (N2), Azotobacter (N3) and Supernitroplat (N4)) and three phosphate biofrtilizer...

phosphorus solubilizing microorganisms are capable of transforming insoluble phosphorus (p) forms to soluble and bioavailable p. the aim of the present study was to isolate p solubilizing bacteria from forest soils around the rock phosphate (rp) mine of koh-e-sepidlar in kohgiluyeh and boyer ahmad province and evaluate their ability in sperber culture medium and wheat straw medium in the presen...

BACKGROUND AND OBJECTIVES The treatment for X-linked hypophosphatemia (XLH) with phosphate and calcitriol can be complicated by secondary hyperparathyroidism and nephrocalcinosis. Furthermore, vitamin D and phosphate stimulate FGF23 production, the pathogenic factor causing XLH. We investigated in XLH patients: 1) whether treatment with the calcimimetic agent, cinacalcet, will block the rise in...

To investigate the effects and mechanism of sphingosine-1-phosphate/sphingosine-1-phosphate receptor on pro-angiogenesis in human colon cancer cells is main objective. The sphingosine-1-phosphate HT-29 SW480 were assessed by tube formation assay. Quantitative real-time polymerase chain reaction was used to detect expression interleukin-8, interleukin-6 vascular endothelial growth factor HT29 af...

With the number of new proton centers increasing rapidly, there is a need for an assessment of the available proton treatment planning systems (TPSs). This study compares the dose distributions of complex meningioma plans produced by three proton TPSs: Eclipse, Pinnacle3, and XiO. All three systems were commissioned with the same beam data and, as best as possible, matched configuration setting...
