Abstract. The efficient development of metal products with high quality usually requires realistic numerical simulations before the manufacturing procedure. choice constitutive model has a considerable influence on predicted material behavior’s description. Several models have been proposed to describe different mechanical phenomena. However, its selection is labored task that expertise. This l...

the recovery and removal of the most organic acids in liquid solutions is usually treated with fixed-bed adsorption processes. among many adsorbents, granular activated carbon (gac) is used to remove organic pollutants such as benzoic acid (ba) from wastewaters conventionally. in this research, adsorption isotherm curves of ba onto gac at varying temperatures 25-60 °c are developed and the amou...
