Atropine-neostigmine and glycopyrrolate-neostigmine mixtures used in 54 premedicated patients for reversal of non-depolarizing neuromuscular blockade were compared for their effects on postanesthetic arousal times. Anesthesia was induced in all patients with thiopental and was maintained with N2O-O2. Atropine-neostigmine significantly delayed arousal for(More)
Membrane distillation (MD) is a thermally driven process where only water vapor is passed through a hydrophobic membrane. Several models have been proposed to study this process, yet most of them assume steady-state conditions. This work presents a new approach to model Direct Contact Membrane Distillation (DCMD) dynamics based on the analogy between(More)
—Membrane distillation is an emerging water distillation technology that offers several advantages compared to conventional water desalination processes. Although progress has been made to model and understand the physics of the process, many studies are based on steady-state assumptions or are computationally not appropriate for real time control.

This paper presents a real time optimization scheme for a solar powered direct contact membrane distillation (DCMD) water desalination system. The sun and weather conditions vary and are inconsistent throughout the day. Therefore, the solar powered DCMD feed inlet temperature is never constant, which influences the distilled water flux. The problem of DCMD(More)
