background: the objective of this work was developing a simple and stable time-based on-line setup for assessing the potential of mercury (hg) vapor adsorption of the commercial sorbents used in air sampling and control operation followed by cold vapor atomic absorption spectrometry (cvaas). methods: a special designed separation chamber was used where reduction of the injected hg (ii) solution...

aim : this study aims to determine the serogroup distribution and molecular diagnosis, as well as antimicrobial resistance profiles among shigella spp. isolated from patients with diarrhea in kerman, southeast of iran.   background : shigella species are frequent cause of bacterial dysentery worldwide. previous studies have been reported that s. sonnei and s. flexneri are the most prevalent ser...

The paper considers the problem of distributed key generation for shared-control RSA schemes. In particular: how can two parties generate a shared RSA key in such a way that neither party can cheat? The answer to this question would have signi cant applications to, for example, key escrow systems. Cocks has recently proposed protocols to solve this problem in the case when both parties act hone...

In this paper, second law analysis for calculations of the entropy generation due to the flow andheat transfer of water-Al2O3 and ethylene glycol-Al2O3 nanofluids inside annuli is presented. Thephysical properties of the nanofluids are calculated using empirical correlations. Constant heatfluxes at inner surface of the annuli are considered and fully developed condition for fluid flowand heat t...

when a distribution network consisting of distributed generations (dgs) is disconnected from upstream network, the system may be exposed to severe power imbalance. in order to prevent the damage of power plants, frequency relays operate and remove dgs from the network. in contrast to traditional methods, the main objective in new methods is to keep dg units in service in the islanded distributi...
