Recent developments in the sensor networks have made the researchers to find the energy efficient routing protocols. Sensor nodes are normally energy constrained and cannot be replaced in most cases. The need for energy efficiency in wireless sensor network is increasing considerably. This article proposed a new model to reduce the energy consumption by the(More)
Sensor nodes in wireless sensor network are severely energyconstrained. This has been a key factor to limit its performance. So far, many energy-efficient routing protocols have been proposed. Clusterbased routing protocols have been paid much attention because of their advantages. However, the cluster-based routing protocols require information on the(More)
With the recent advances in Micro Electro Mechanical System (MEMS) technology, low cost and low power consumption wireless micro sensor nodes have become available. However, energy-efficient routing is one of the most important key technologies in wireless sensor networks as sensor nodes are highly energy-constrained. Therefore, many researchers have(More)
PURPOSE Traditionally, the surgical repair of umbilical hernia in cirrhotic patients with ascites is avoided because of a significant recurrence rate and perioperative morbidity/mortality. However, recent reports recommend early elective surgery in these patients because surgery-related complications can be reduced with minimally invasive surgery and(More)
This study investigated the effect of lemongrass essential oil (LGEO) on the infectivity and viral replication of norovirus. Murine norovirus 1 (MNV-1), a surrogate of human norovirus, was preincubated with LGEO and then used to infect RAW 264.7 cells in a plaque reduction assay. LGEO exhibited a significant reduction in MNV-1 plaque formation in both time-(More)
