Transient signals to increasing concentrations of the dyes red, green and blue, obtained by the flow analysis system and detection by webcam and spectrophotometer... The

For the construction of control charts, the following samples divided into five sets were prepared, I: 10 diesel samples free of biodiesel; II: 20 samples under control

The aim of this study was to evaluate the antimicrobial potential of bio-oil when added to B10 blend (diesel and biodiesel) with oil-deteriorating microorganisms and to

The efficiency of the method depends on effective parameters such as pH of the SP, carrier concentration, concentration of picric acid as counter anion, type and concentration

Twenty functional monomers were evaluated through semi-empirical quantum chemistry method and three MIPs were synthesized using the monomers acrylamide (M5), acrylic acid (M4)
