Clustering has long been regarded as an efficient technique for data collection in wireless sensor networks. The approach divides network into clusters and makes cluster heads (CHs) responsible for data aggregation. However, due to the constraints on available resources, a sensor node is likely to be selfish and refuse to declare itself as a cluster head. In this paper, we propose a game-theory...

Methods include the pulverizing of J machinery prior to sale as fertilizer ( P > *931) and the Beccari system of f...

In the past, acid mine drainage (AMD) associated with coal mining operations and the disposal of coal refuse have been a driving force behind research efforts on the properties of coal combustion products (CCPs) [1]. The results from research over the last 15 years clearly indicate that bulk-blended CCP has the potential to ameliorate AMD production in coal refuse as long as acid-base balance c...

A number of prominent and often well-reasoned cases have increasingly defined a limited right, on the part of involuntarily detained psychiatric patients, to refuse treatment.3-12 Historically, most of these cases dealt with prisoners,6 or with patients who had religious objections to the treatments being imposed.3 However, as the mental health bar expanded and as scholarly critiques proliferat...
