Chitosan-pectin, chitosan-alginate and chitosan-pectin-alginate scaffolds were prepared by freeze-drying technique. The physicochemical characteristics of the scaffolds were characterized by FTIR and SEM. The biological activities like antibacterial assessment, swelling behavior, biodegradation and cytotoxicity study of the prepared scaffolds were evaluated. The results show high swelling prope...

expansive soils are considered a worldwide problem as they cause extensive damage tocivil engineering structures. an important characteristic of expansive soils is theirsusceptibility to volume change due to the phenomenon of wetting and drying. this paperpresets the effect of pore water quality on the swelling and shrinkage behavior of anexpansive soil during wetting and drying cycles. thirty ...
