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 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 ...
This paper presents results for the minimization of fuel consumption in a batch furnace. Several different criteria are used and minimized with respect to time- dependent process and control variables. As would be expected, the results show that globally t ...
An optimization tool to identify optimum structure/parameters of hybrid electric vehicles (hereafter abbreviated as HEV) is proposed, which can take account of various criteria regarding environmental impacts, cost minimization, or minimum fuel consumption ...
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. ...
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 ...
The stop-effect, a drastic increase of the reaction rate when the feed concn. of a reactant is switched to zero, was studied for the dehydration of ethanol to ethylene on y- alumina at 180 and 200 DegC. Two basic models exist in the literature to describe ...
Comprehensive in-situ bioreactor monitoring and control based on a midinfrared spectroscopic sensor system M. Rhiel1, C. Cannizzaro1, S. Valentinotti2, I. Marison1, U. von Stockar1 1 Institute of Chemical Engineering, 2Institute of Automatic Control Swiss ...
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 ...
