Opis:: The raw coal was utilized as adsorbent based on its remarkable adsorption ability of coal slime to organic compounds in the flotation process. This paper mainly investigates adsorption behaviors of benzpyrole (BZP), pyrrole (PR) and benzoic acid (BA) on powdered coal (PC). In the monocomponent solution, the removal efficiencies of BZP, PR and BA reached 85.23%, 55.02% and 24.84% at PC dosage of 20 g/dm3. Adsorption behaviors of three pollutants fitted perfectly to the pseudo-second order kinetics model and liquid film diffusion occupied the largest proportion in rate-limiting step according to the diffusion rates. Furthermore, the influences of pH on adsorption behaviors and competitive adsorption mechanism of three pollutants were also reported.

Opis:: Wireless sensor networks have received wide attention recently across the indoor and outdoor applications. On the other hand, more and more application scenarios require sensor nodes to be mobile, which imposes new technological challenges for security. Key management is the core for secure data communications among the resource-constrained sensor nodes. In this paper, based on the Group Diffie-Hellman key agreement protocols and the energy level of each node in the network, we propose Energy Aware Group Diffie-Hellman key management protocol for mobile wireless sensor networks. The simulation results show that the proposed key management protocol provide significant improvement in maximizing the lifetime of networks.
