Unicolonial ant populations are the most extensive cooperative units known in nature, forming networks of interconnected nests extending sometimes hundreds of kilometers.

in this paper, a faster method for embedding cryptographic information in the image ispresented by expressing the concept of latent prints (steganography). data is encrypted bytwo methods before embedding to increase reliability. then they are embedded into the imageby a button, a method has been expressed to reduce potential noise impact on the wayinformation is encoded.

We studied the frequency of malfunction, variability in rate of nebulization, and effect of this variability on aerosol particle size of eight disposable jet nebulizer models produced by six manufacturers. Four of eight models showed visual signs of malfunction, including spraying of large, individually visible droplets, leaking of nebulizer solution, and air leaks that completely prevented neb...
