This paper illustrates through distillation examples how the bounded Newton homotopy method considerably extends the area of convergence compared with the unbounded one. Sidestream column configurations with exact mole fraction specifications are used as demonstrative test cases. Starting point multiplicity is found to be a real challenge when solving distillation problems with Newton homotopy-...

Ten patients with bronchial asthma and ten control subjects were exposed to sidestream cigarette smoke (passive smoking) for one hour in an environmental chamber. All subjects showed the same increase in carboxyhemoglohin as a result of the exposure: 0.40 percent. The asthmatic group demonstrated a significant linear decrease in pulmonary function during this exposure. After one hour of smoke, ...

ANITATM Mox is a new one-stage deammonification Moving-Bed Biofilm Reactor (MBBR) developed for partial nitrification to nitrite and autotrophic Nremoval from N-rich effluents. This deammonification process offers many advantages such as substancial reduction in aeration requirement and sludge production along with the lack of need for an external carbon source. In this paper, we present the ex...

The objective of this study was to determine the particle size and mass output of salbutamol from different nebulizers used under simulated breathing conditions. Seven nebulizer/compressor combinations were assessed. Each nebulizer was charged with 5 mg salbutamol solution and connected to a breathing simulator operating at tidal volumes of 150 mL and 600 mL. Nebulizers were operated for 15 min...
