Mobile devices in delay tolerant networks (DTNs) are used and carried by people, whose behaviors could be described by social models. Understanding social behaviors and characteristics of mobile users can greatly help the routing decision in DTN routing protocols. However, to obtain the stable and accurate social characteristics in dynamic DTNs is very(More)
Mobile opportunistic networks (MONs) are intermittently connected networks, such as pocket switched networks formed by human-carried mobile devices. Routing in MONs is very challenging as it must handle network partitioning, long delays, and dynamic topology. Flooding is a possible solution but with high costs. Most existing routing methods for MONs avoid(More)
The oxidation rate of arsenopyrite by dissolved oxygen was measured using a mixed flow reactor at dissolved O2 concentrations of 0.007-0.77 mM, pH 1.8-12.6, and temperatures of 15-45 degrees C. As(III) was the dominant redox species (>75%) in the experimental system, and the As(III)/As(V) ratio of effluent waters did not change with pH. The results were(More)
