Sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. So it is can be used as a sugar source in many processes. Lignin and hemicellulose must be removed before hydrolysis of cellulose. Several different pretreatment approaches have been studied. The purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

random number generation is one of the human abilities. it is proven that the sequence of random numbers generated by people do not follow full randomness criteria. these numbers produced by brain activity seem to be completely non stationary. in this paper, we show that there is a distinction between the random numbers generated by different people who provides the discrimination capability, a...
Introduction: Disinfection of the cavity preparation after caries excavation can lead to the elimination of bacterial remnants that can be responsible for recurrent caries, postoperative sensitivity, and failure of the restoration. The purpose of this study was to evaluate the effects of two disinfectants on microleakage of composite restorations in primary teeth. Metho...
Glycyrrhiza glabra residue (GGR) was efficiently subjected to concentrated phosphoric acid (PA) pretreatment with/without surfactant assistance, and promising results were obtained following separate enzymatic hydrolysis and fermentation (SHF) of the biomass. Pretreatment was carried out using 85 % PA either at 50 or 85 °C with 12.5 % solid loading for 30 min. In parallel experiments, ...
in this research, microwave-assisted hydrodistillation (md) with pretreatment ultrasound (us) 45 and 90 min of essential oils from fresh aegle marmelos peel were used and the results were compared with those obtained by hydrodistillation technique (hd) in terms of extraction yield/efficiency, extraction time, chemical composition and quality of the essential oil. all experiments were performed ...
the present work was performed to show the possible interaction of gab a, and gabab receptors in catalepsy. the following results were obtained: 1- muscimol (mus), a gabaa agonist, induced catalepsy. this effect was dose-dependent. baclofen (bac), a gabab agonist, had no effect in this respect. 2- catalepsy induced by muscimol was potentiated by pretreatment of animals with bicuculline (bic), a...
