The progressive development of civilization and intensive industrialization has contributed to the global pollution of the natural environment by heavy metals, especially the soil. Degraded soils generally contain less organic matter, and thus, their homeostasis is more often disturbed, which in turn manifests in changes in biological and physicochemical properties of the soil. Therefore, new p...

Arid ecosystems are characterized by high spatial heterogeneity, and the variation among vegetation patches is a clear example. Soil biotic and abiotic factors associated with these patches have also been well documented as highly heterogeneous in space. Given the low vegetation cover and little precipitation in arid ecosystems, soil microorganisms are the main drivers of nutrient cycling. None...

wheat starch is the most common type of starch in iran as well as many other parts of the world with enormous applications in food and non-food products. to improve its physicochemical properties or create new functionalities, starch can be modified by changing its molecular structure. amongst different methods for starch modification, physical methods have received more attention recently. pre...

the effects of zinc oxide nanorod (zno-n) incorporation on thephysicochemical properties of tapioca starch / bovin gelatin composite film such as water absorption capacity (wаc), water solubility and permeability to water vapour (wvp) were investigated. in this search, zno-n was homogenized by sonication and added into tapioca starch / bovine gelаtin dispersions аt different concentrations (e.g...

in this study, the effect of mentha piperita essence (mpe) incorporation into cassava films on the hydrophilic and physicochemical properties of the resulting biodegradable films was investigated. the properties included solubility, moisture uptake and contact angle. mpe was added into biodegradable films at different amounts (1, 2 and 3%, w/w total solid). all biofilms were plasticized with 40...

this study aims to determine the effect of fermentation condition and saccharomyces strains on the ph, foam property and co2 concentration of non-alcoholic beer (ma-al-shaeer). for this, the beer samples were inoculated with four different species of saccharomyces (saccharomyces rouxii 70531, s. rouxii 70535, s. ludwigii 3447 and s. cerevisiae 70424) and fermented for 48h in both aerobic and pe...

The long-term impact of biochar on soil properties and agronomic outcomes is influenced by changes in the physical and chemical properties of biochars that occur with time (aging) in soil environments. Fresh biochars, however, are often used in studies because aged biochars are generally unavailable. Therefore, a need exists to develop a method for rapid aging of biochars in the laboratory. The...
