1. Strong Stability Preserving Runge-Kutta Methods Applied to Water Hammer Problem
ABSTRACT The characteristic method of lines is the most used numerical method applied to the water hammer problem. It transforms a system of partial differential equations involving the independent variables time and space in two ordinary differential equations along the characteristics curves and then solve it numerically. This approach, although showing gr

12. Substituting sucralose with rebaudioside A in soy foods: equivalent sweetness, physicochemical analysis, microbiological assessment and acceptance test
Abstract Stevia rebaudiana (Bert.) Bertoni contains steviol glycosides with emphasis to rebaudioside A, which presents a stronger sweet flavor, more stability, good solubility and lower bitter residual taste, which benefits its application in foods and drinks. The objective of this study was to determine the equivalent amount of rebaudioside A necessary to p
