Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Reducing the use of non-renewable fossil energy reserves together with improving the environment are two important reasons that drive interest in the use of bioethanol as an automotive fuel. Conversion of sugar and starch to ethanol has been proven at an i ...
At high growth rates, the biomass yield of baker's yeast (Saccharomyces cerevisiae) decreases due to the prodn. of ethanol. For this reason, it is std. industrial practice to use a fed-batch process whereby the specific growth rate, m, is fixed at a level ...
During the anaerobic batch cultivation of Kluyveromyces fragilis on a complex medium contg. glucose (100 g/L), EtOH was produced at levels resulting in the inhibition of growth and EtOH formation. Continuous extn. of the EtOH using transmembrane distn. res ...
Global climate change mitigation policies call for increasing use of biomass fuels as renewable substitutes to fossil energy resources. Quantified targets for biofuels introduction in to the market exist in the United States, the European Union, and a numb ...
Attention has been focused on the possibility of an interaction between the endorphinergic system and ethanol intake. In the present study, the effects of subcutaneous (SC) administration of beta-endorphin (beta-E) (0.25, 1 and 5 micrograms/kg) and/or nalo ...
The effects of subcutaneous (SC) administration of D-Ala2-Met5-enkephalinamide (DAME) (1, 10 and 100 micrograms/kg), synthetic analog of Met-enkephalin, on the acquisition of ethanol preference were studied in male Wistar rats. Under our procedural conditi ...
Systematic errors due to the neglect of water and/or ethanol partition between liq. and gaseous phases are discussed for bioreactors equipped with or without a condenser. Both water vapor and ethanol vapor are present in the off-gas leaving the condenser. ...
Using a paradigm by which rats forced to drink a weak ethanol solution (2.5% w/v) (conditioning session) develop ethanol preference in consecutive retention testing days, the effects of the administration of the kappa opioid antagonist MR-2266-BS, prior to ...
The products of hetero-Diels-Alder reactions (sultines) and cheletropic addition reactions (sulfolenes) between 1,3-dienes and sulfur dioxide can be distinguished by their O-17 NMR shifts. Experimental data have been collected for derivatives of 3,6-dihydr ...
The effects of subcutaneous administration of leu-enkephalin (LEU-E) (10, 100 and 300 micrograms/kg) and LEU-E (100 micrograms/kg) plus naloxone (2.5 mg/kg) on ethanol preference and fluid intake have been investigated in rats. Under our procedural conditi ...
