pollution arising from plastic waste materials caused a great worry for researchers who are interested in protection of environment. this problem shifts their subject to bio-polymers for applications in packaging industries. however, their low water barrier properties are a critical problem. the effects of citric acid and methyl cellulose on water vapor and oxygen permeabilities and mechanical ...

in this study, wasinvestigated the effect of two thickening agents, carboxymethyl cellulose (cmc) and guar on the rheological properties of set fruit yogurt. viscoelastic modulus (g' , g'), apparent viscosity and complex viscosity increased and loss factor decreased by increasing carboxymethyl cellulose and guar content up to 0.2% and 0.06% respectively. however, in the concentrations...

application of outflow water from treatment plants for irrigation as a non-usual water resource is being developed due to the lack of usual water resources in iran. activated carbon as a conditioner in water treatment procedures causes undesired changes in hydraulic properties of porous media and soil degradation. in this paper, the effects of activated carbon concentration on hydrodynamic prop...

During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for pr...

introduction: resin composites are an important part of restorative treatment in modern dentistry. there are many trademarks available in iran market and physico-chemical properties of many of these resin composites are not evaluated yet. this study was carried out to evaluate the physico-chemical properties of four available resin composites and also to assess the effect of aging on their prop...

Population’s exponential growth along with drought has increased water resources limitation, especially in arid and semi-arid area. Therefore, the use of non-conventional water is an important tool for water resource management. If unconventional water has no negative impact on soil properties and water, it can be used for irrigation coupled with desertification projects. So, this paper tries t...
