chemical oxidation is one of the most suitable treatment methods for reducing organic pollutants and the number of pathogens remaining in secondary effluents. ozone is the most powerful oxidizing agent commonly used because of it's many advantages over chlorination. in this study the efficiency of ozonation in advanced wastewater treatment of sahebgharanieh plant has been determined. ozone gene...

this study was aimed at investigating the photocatalytic degradation of ciprofloxacin (cip) antibiotic in aqueous solution using immobilized zno nanoparticles on glass plate. x-ray diffraction, atomic force microscopy, and scanning electron microscopy were applied to characterize the nanoparticles. to do so, the zno nanoparticles were synthesized through the chemical precipitation method and we...

background: application of potassium ferrate is a chemical oxidation approach used for water and wastewater treatment. the aim of this study is to apply central composite design (ccd) and response surface methodology (rsm) to optimize potassium ferrate consumption in the treatment of wastewater from carpet industries. methods: samples in this experimental study were collected from wastewater, o...

background: mature landfill leachate is a complicated mixture which is resistant to biological treatment processes. the treatment of mature landfill leachate by struvite precipitation and fenton oxidation was the main objective of the current research. methods: struvite with the phosphate/ammonia/magnesium molar ratio of 1/1/1.05 was considered during all experiments. five initial phs of 3, 4, ...

by the year 2020, the incidence of trauma has been predicted to rise worldwide and the death rate is expected to increase from 5.1 million to 8.4 million. the most important cause of death and severe morbidity up to the age of 45 years is traumatic brain injury, with or without polytrauma. since the early 1970s, traffic-related deaths in germany have dropped continuously—with the exception of t...

background: external beam radiotherapy (ebrt) is mainstay of treatment in patients with locally advanced cervical carcinoma (lacc). three dimensional conformal radiotherapy (3dcrt) and intensity modulated radiotherapy (imrt) are mainly used in ebrt. however which one is superior is still controversial. materials and methods: forty patients of lacc treated with imrt were selected for this study....

conclusions these results revealed that resveratrol has beneficial effects on kidney by extenuating the oxidative stress and down-regulation of rage expression. results in resveratrol-treated rats with diabetes, malondialdehyde levels, plasma glucose and expression of rage were significantly reduced compared with the untreated group. moreover, the total antioxidant and insulin levels significan...

context advanced glycation end-products (ages) are signaling proteins associated to several vascular and neurological complications in diabetic and non-diabetic patients. ages proved to be a marker of negative outcome in both diabetes management and surgical procedures in these patients. the reported role of ages prompted the development of pharmacological inhibitors of their effects, giving ri...
