in this paper, a schwarz-christoffel method for generating two-dimensional grids for a variety of complex internal and external flow configurations based on the numerical integration procedure of the schwarz-christoffel transformation has been developed by using mathematica, which is a general purpose symbolic-numerical-graphical mathematics software. this method is highly accurate (fifth order...
Design of selective cyclooxygenase-2 (COX-2) inhibitors is still a challenging task because of active site similarities between COX isoenzymes. To help with this issue, we tried to generate a 3D-QSAR (3 dimensional quantitative structure activity relationship) model that might reflect the essential features of COX-2 active sites. Compounds in a series of resveratrol derivatives inhibitors with ...
