   Physical study of nano ribbon, tetragonal bundled and isolated nano tube SiC (7,0) are part of our project in knowing new nano material such a silicon carbide. These studies have been performed by density function theory. Effect of ribboning, tubulating and tetragonal bundling on the physical properties such as stability, structural constants, optical physics, chemical parameters and mag...

some physical properties and chemical compositions of two cultivars (semsouri and shahabadi) of cantaloupe studied during four different stages of maturity from fruit set to completely ripe. the physical properties investigated were the geometric mean diameter (gmd), specific gravity (sg), mean firmness (mf), rind, seed (%) and flesh (%). the chemical compositions were brix, titrable acidity (t...

extracellular polymeric substances are defined as high molecular weight compounds secreted by the microorganisms in the surrounding area. since these extracellular substances are mainly polysaccharide, they are named exopolysaccharide. microbial exopolysaccharides composed of sugar residue have growing interest as a new class of microbial products which can be used in food, pharmaceutical, and ...

Plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. The aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including Hordeum bulbosum, Poa bulbosa, Bromus tectorum. First, soil samples were taken in the depth of 0-3...
