We assessed current water consumption during liquid fuel production, evaluating major steps of fuel lifecycle for five fuel pathways: bioethanol from corn, bioethanol from cellulosic feedstocks, gasoline from U.S. conventional crude obtained from onshore wells, gasoline from Saudi Arabian crude, and gasoline from Canadian oil sands. Our analysis revealed that the amount of irrigation water used...

The influence of information load on ethanol and water intake of altered magnetic background was studied in initially ethanol-aversive Wistar rats. A paradigm of free choice between 10% of ethanol solution and water was applied. Daily exposure to weak disturbances of ambient magnetic field (MF, up to 210 mT) caused by various ferromagnetic objects under conditions of free behavior (zero level o...

We present a series of experiments to study the silanization of the silica surface of a fiber Bragg grating biosensor. A simple 4-layer attachment model is developed to describe the bonding of 3-aminopropyl triethoxysilane (APTES) or 3-aminopropylethoxydimethylsilane (APMDS) to the silica surface when both APTES and APMDS are dissolved in water or in pure ethanol. An adsorbed water layer is cre...

recently, extracts from various parts of a. occidentale had been massively investigated in themanagement and treatment of various ailments which include but not limited to diabetes, malaria,yellow fever as well as diarrhea. stem bark of anacardium occidentale was extracted with water andethanol. antioxidant activities of the extracts were using dpph. for estimation of effectivediffusivity, math...

This study examined the relationship between saccharin drinking, open field behaviour and ethanol drinking in Wistar rats. Correlational analysis revealed that both absolute saccharin drinking and an increase in total fluid intake in the presence of saccharin positively correlated with the initial acceptance of increasing ethanol concentrations in a two-bottle choice situation (2-8% v/v ethanol...

This study compared the urinary excretion characteristics of ethyl glucuronide (EtG) with that of ethanol, with focus on the effect of water-induced diuresis. Six healthy volunteers ingested an ethanol dose of 0.5 g/kg (range 25.0-41.5 g) as 5% (v/v) beer in 30 min and the same volume of water after 3 h. Urine collections were made before starting the experiment and at timed intervals over 31.5...

Fuel-grade ethanol (76L of E95, 95%v/v ethanol, 5%v/v hydrocarbon mixture as a denaturant) was released at the water table in an 8150-L continuous-flow tank packed with fine-grain masonry sand. Ethanol, which is buoyant and hygroscopic, quickly migrated upwards and spread laterally in the capillary zone. Horizontal migration of ethanol occurred through a shallow thin layer with minimal vertical...

BACKGROUND Liquid hot water (LHW) pretreatment is an effective and environmentally friendly method to produce bioethanol with lignocellulosic materials. In our previous study, high ethanol concentration and ethanol yield were obtained from water-insoluble solids (WIS) of reed straw and corn stover pretreated with LHW by using fed-batch semi-simultaneous saccharification and fermentation (S-SSF)...

Bioethanol is considered to be the most optimistic biofuel. Hydrated ethanol with more than 2% (v/v) of water is not completely miscible with gasoline, so complete dehydration of ethanol is required. Distillation alone cannot concentrate ethanol beyond its azeotropic point so various other methods are used to concentrate ethanol to completely anhydrous state in short span of 93-99.80% (w/w) eth...
