in this experiment, physical and chemical characteristics and estimation of effective fiber and digestibility of some agricultural by-products such as lerd, pulp and date kernel, grape pomace, pistachio hulls, lime and rice straw were determined by using in vitro technique. experimental data were analyzed as a complete randomized design, with three replicates. physical and chemical characterist...
Geopolymers are inorganic polymers formed from the alkaline activation of amorphous alumino-silicate materials resulting in a three-dimensional polymeric network. As a class of materials, it is seen to have the potential of replacing ordinary Portland cement (OPC), which for more than a hundred years has been the binder of choice for structural and building applications. Geopolymers have emerge...
Many different crop species were selected for a common suite of 'domestication traits', which facilitates their use for studies of parallel evolution. Within domesticated rice (Oryza sativa), there has also been independent evolution of weedy strains from different cultivated varieties. This makes it possible to examine the genetic basis of parallel weed evolution and the extent to which this p...
Common technologies for heavy metal removal are membrane separation, ion exchange, electro-deposition, and chemical precipitation. These methods prove to be costly and inept, especially in removing trace amounts of heavy metals [2]. Another disadvantage is the production of sludge or mud, which requires proper disposal and confi nement [3]. On the other hand, adsorption eff ectively removes con...
