Flow boiling experiments for two new non-azeotropic, three-component refrigerant mixtures (HP80 and HP62) and R-502 have been carried out inside a 12 mm bore, horizontal tube. Local boiling coefficients for HP62 are slightly larger that those for R-502 und ...
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. ...
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 ...
A method and apparatus serve to determine spectroscopically a concentration of ethanol in a test sample of an alcoholic aqueous beverage. The determination is based upon providing calibration data which establish a relation between (A) a plurality of trans ...
Flow boiling experiments for two new non-azeotropic, three-component refrigerant mixtures (HP80 and HP62) and R-502, the azeotropic refrigerant binary mixture they are replacing, have been carried. Comparative results show that local flow boiling heat tran ...
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 ...
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 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 ...
