Heavy metal ions are known to induce generation of a large number reactive oxygen species (ROS). Glutathione S-transferases (GSTs) play an important role in adaptation and response oxidative stress. GSTM1, GSTT1, GSTP1 genes have numerous described polymorphisms, the most significant being Ile105Val deletion ones. Our objective was study relationship between genetic polymorphism blood levels me...

Abstract The focus of this study is to see if Friction Stir Processing can improve the properties an aluminium alloy with Boron Nitride (BN) particles on surface. (FSP) a new surface alteration technique that uses friction cause plastic deformation, resulting in grain refining and improved mechanical properties. To process 2024 plates, straight cylinder tool was used under varying parameters co...

Precious metal refining from ore or electronic devices includes hydrometallurgical processes with major concern about toxicity wastewater production. As an alternative, one-step electroleaching-electrochemical deposition process (EL-ECD) using ionic liquid mixtures was evaluated for palladium and gold recovery. A halide based combined a diluting chosen among ten electrolytes after cyclic voltam...

one of the most important stages in sugar industry that making wastewater and contamination is the water obtained to washing of co2 in mazoot furnace and related pumps. amount of water consumption in this stage is about 30 to 35 percent of weight of sugar beet, so amount of this stream is considerable. mixing of carbon black and water compose the colloid in liquid phase. these colloids do not s...

We investigate forcing notions with the rectangle refining property, which is stronger than the countable chain condition, and fragments of Martin’s Axiom for such forcing notions. We prove that it is consistent that every forcing notion with the rectangle refining property has precaliber א1 but MAא1 for forcing notions with the rectangle refining property fails.
