With the tremendous advent of internet and related technologies the significance of adhoc networks are increasing day by day. Adhoc networks are infrastructure less, self-creating wireless networks. Since nodes are mobile and topology changes dynamically route selection becomes very difficult. This type of network is easily vulnerable to internal and(More)
We tested the hypothesis that endothelin-1 (ET-1), a cerebrovasoconstrictive peptide, would alter microvascular oxygen balance during focal cerebral ischemia. In this study, male Wistar rats were placed in control (n=9) and ET-1-treated (n=9) groups. Cortical ischemia was induced by middle cerebral artery (MCA) occlusion in isoflurane (1.4%) anesthetized(More)
Objective To study the awareness and execution of road safety practices among school children. Results Questionnaires were completed by 234 (93.6%) of 250 children who were approached. The mean age of the children was 14.3 (range 13-15 years). 70 (29%) were girls and 141 (60%) were boys; 23 (9.8%) did not fill in the personal details. 12 girls had driven a(More)
Objective To implement SATS (South African Triage system) in a pediatric emergency department. Tools: Nurses on triage duty applied SATS to all children attending ED during the study period; data was compiled and analysed. SATS is a validated four-category color-coded triage system. Rapid evaluation of clinical discriminators and an age-appropriate(More)
The paper deals with the working of wireless sensor network. In which it compare the different working of wireless sensor network. Basically there are two types of wireless sensor network, Traditional sensor network and the Hierarchical sensor network. Traditional sensor network is the already available network which uses more battery. But hierarchical(More)
