Secrecy analysis of wireless sensor network in smart grid with destination assisted jamming

In this study, the authors investigate the physical layer security performance over Rayleigh fading channels in the presence of impulsive noise, as encountered, for instance in smart grid environments. For this scheme, secrecy performance metrics are considered with and without destination assisted jamming at the eavesdropper's side. Specifically, they derive analytical expressions for the secrecy outage probability (SOP), at the legitimate receiver. Finally, numerical results are provided to verify the accuracy of the authors' derivations. From the obtained results, it is verified that the SOP, without destination assisted jamming, is flooring at high signal-to-noise-ratio values and that it can be significantly improved with the use of jamming.

Antidotal Efficacy of Activated Charcoal in Presence of Jam, Starch and Milk

The effect of addition of jams, marmalades, starches and milk products on the adsorptive capacity of activated charcoal for acetylsalicyclic acid was determined in vitro. The addition of these products to an aqueous suspension of activated charcoal decreased the adsorption of acetylsalicylic acid from 98% to 95% or 90% (jams and marmalades) or to 80% (milk). Starches had no effect. It appears that the use of jams to make ingestion of activated charcoal easier is acceptable.
