conclusions our successful extraction of purified lps from e. coli isolates of uti patients’ urine samples can be an important step to understand the uti disease conditions. results the silver-stained gel demonstrated both smooth and rough type lps by showing trail-like band patterns with the presence and lacking o-antigen region, respectively. coomassie blue staining showed no band assuring th...

background and objectives: making stacking gels for polyacrylamide gels in the laboratory by conventional methods is laborious and time consuming. considering the role of temperature in polyacrylamide gels with respect to electrical resistance and viscosity, we assumed that decreasing the temperature would cause an increase in electrical resistance and viscosity.  ultimately, a downward tempera...

This study has been investigated, the effects of three different polar polyacrylamides (anionic, cationic, and nonionic) on asphaltene deposition in porous media. All experiments were carried out in various dead oil flow rates (0.2, 0.1 and 0.02 cc/min) and different polymer concentrations (500, 2500, 4000 ppm). The results indicated that asphaltene precipitation was affected by the presence of...

• Microalgae harvesting is a major bottleneck to microalgae-based biofuel production. Flocculation the most versatile, energy-efficient and cost-efficient process. Polyacrylamides exhibit high performance at different operation scales. Comprehensive analysis of polyacrylamide-microalgae flocculation was presented. Properties polyacrylamide microalgae culture influence biomass touted as highly p...
