sulfonamides are the first effective chemotherapeutic agents used for several years to cure or prevent systemic bacterial infections. in addition, this agents showed anti-carbonic anhydrase and cause cell cycle perturbation in the g1 phase, disruption of microtubule assembly, suppression of the transcription activator nf-y, angiogenesis and matrix metalloproteinase (mmp). in recent years, novel...

in this study, optimized adaptive neuro-fuzzy inference system (oanfis) was employed on a set of daily, weekly, 10-days and monthly data of inflow water into the alavian dam to predict the real-time inflow of the reservoir. sequential and exhaustive search algorithms were used to determine the numbers and time steps of the model inputs and also reducing the prediction’s errors. in sequential se...

in this study, the densities, excess molar volumes and partial molar volumes of four binary systems containing n,n-dimethyl acetamide (dmac) with 1-alkanols (1-butanol up to 1-heptanol) are measured at 298.15 k. the results showed both constructive and expansive excess volumetric behavior for studying binary mixtures. deviation values of heavy alcohol have more positive and less negative excess...
