Contamination of effluents with chemicals is a serious problem that impacts human health. Methylene blue cationic dye found frequently in industrial and urban sewages. In this work, dried grinded seeds peels nance were used as biosorbents aqueous solutions at pH 7 10 (simulating textile effluents) finding Langmuir Freundlich isotherms adequately described the sorption. Adsorption efficiencies l...

This study is focused on removing toxic aniline from aqueous solutions using advanced oxidation process by UV/ peroxy disulfate. In this study, the effect of various parameters including pH (3-9), the level of radiation (ultraviolet 30 watt lamp, number 2-5), peroxy disulfate dose (0.02 – 0.08 mol/l) and the initial concentration (20 – 100 mg/l) at different contact times (10 – 60 min) on the e...

Water quality management policies on a river basin scale are of special importance in order to prevent and/or reduce environmental pollution caused by human sources. Industrial effluents are a priority issue particularly in Urban Wastewater Systems (UWS) that receive mixed household and industrial wastewaters, apart from rainfall water. In this paper, we present an analysis and implementation o...

background: methanol is a colorless and poisonous liquid that is commonly used as an industrial and household solvent. methanol poisoning is a rare but extremely hazardous form of in toxication that affects the central nervous system and causes visual disorder, drowsiness, seizures and coma.  case presentation: a 29-years-old man with methanol intoxication presented with drowsiness and acidosis...

We study the effect of wealth on individual and household labor supply using a large, newly-collected sample of lottery players in Sweden. Using high-quality administrative data for roughly 2.5 million lottery players, we find that winning a lottery prize modestly reduces labor earnings, with the effects roughly constant over time and persisting more than 10 years. We find both intensive and ex...
