Raw bagasse or sugar cane cellulosic residues were modified using acylation grafting with fatty acid. The capability of the grafted bagasse to absorb oil from aqueous solution was studied and compared with the raw bagasse. It was found that the grafted material was significantly more hydrophobic than the raw bagasse. This grafted bagasse had little affinity for water and good affinity for oil. ...

We analyze a two-firm spatial competition model in which firms must transport raw materials from a raw material site to their locations in order to produce. The model has two equilibrium configurations: (i) a symmetric one in which firms locates equidistantly from the raw material site, and (ii) an asymmetric one in which one firm locates at the raw material site and the other locates distantly...

slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. maximum glucose yield ...
