AsuquoProblem statement: The degree of toxicity of crude extracts of Aspilia Africana (Bush marigold) leaf on the basis of routes and dosages of administration were investigated. 204 healthy, male Swiss albino mice (20-25g) were used in three consecutive studies. Approach: In the first and second study, oral and intraperitoneal doses of 100, 500, 1000, 2000 and 4000 mg kg-1 body … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 3 · 28 Nov 2011 · 8,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobility and Density Aware AODV Protocol Extension for Mobile Adhoc Networks-MADA-AODVS. Deepa, G.M. Kadhar NawazProblem statement: In this study, we proposed a method to improve the performance of AODV by reducing overhead by adopting a route message propagation mechanism. According to the new scheme, a node will be selected to forward a routing request message if and only if a condition based on its mobility (speed) and number of neighbors is satisfied. If the … …Journal of Computer Science, Vol. 8, Issue 1 · 26 Oct 2011 · 7,288 accessesView PDFCite
