ALL modern volatile anesthetics produce carbon monoxide in strongly exothermic reactions with anhydrous carbon dioxide absorbents. Although desflurane produces the most carbon monoxide, the reaction with sevoflurane produces the most heat. Using real anesthesia machines, sevoflurane, and desiccated Baralyme® (Allied Healthcare Products, Inc., St. Louis, MO), peak absorbent canister temperatures...

abstract in this work, fe3o4-graphene oxide nanocomposite (go-fe3o4) was prepared as effective absorbent for magnetic solid phase extraction (mspe) of trace quantities of cadmium ions in environmental water and rice samples using 1, 2-dihydroxy anthraquinone-3-sulphonic acid, sodium salt (alizarin red s) and flame atomic absorption spectrometry (faas). the   go-fe3o4 was characterized by scanni...

Polypropylene hollow fiber membrane (PPHFM) contactor, with aqueous solution absorbent such as sodium hydroxide (NaOH), monoethanolamine (MEA) and diethanolamine (DEA), was designed and used to separate and fix CO2 from CO2/N2 gas mixtures. The factors that influence the separation properties of CO2/N2 were investigated. It was found that the CO2 removal efficiency is the best by using MEA solu...

Removal of spilled petroleum oil from water bodies using hydrophobic porous absorbent has garnered considerable attention due to the simplicity, large-scale adaptability and robustness process. However, use nonbiodegradable synthetic during cleanup raised a secondary concern such as generating plastic pollutants that can accumulate in marine other ecosystems. To encounter this potential hazard,...

The electromagnetic backscattering of a crosscut of a cruise missile coated by a thin homogeneous layer made of radar absorbent material is modeled using a finite element method. Based on the radar cross section and a reflection coefficient, optimization problems are formulated for evaders and interrogators leading to optimal material parameters for the coating and optimal monostatic radar oper...
