In this paper, the effect of surface area of reaction layers in gas diffusion electrodes on oxygen reduction reaction was investigated. For this purpose, various amounts (0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5 and zero %wt of total loading of reaction layer) of single walled carbon nanotube (SWCNT) were inserted in the reaction layer. The performance of gas diffusion electrodes for oxygen reduction re...

The purpose of this letter is to revisit the nonlinear reaction-diusion modelin porous catalysts when reaction term is fractional function of the concen-tration distribution of the reactant. This model, which originates also in uidand solute transport in soft tissues and microvessels, has been recently givenanalytical solution in terms of Taylors series for dierent family of reactionterms. We a...

introduction: olanzapine (zyprexa) has become one of the most commonly prescribed atypical antipsychotic drug in iran, at least in part due to its low potential to cause extra-pyramidal side effects. case: a 54-year-old man, who was a known case of schizophrenia from 10 years ago and within the recent years, was under periodic medical treatment by antipsychotic drugs. conclusion: neurologists a...

background: the reporting of adverse drug reactions (adrs) by nurses in hospitals is very important.aims: this study was aimed at investigating the impact of an educational intervention to improve adr reporting and whethertrained nurses had better knowledge, attitude, and practice toward adr reporting. materials and methods: a total of 300 nurses in a tertiary care teaching hospital in tehran, ...
