The present study deals with the induction of mutations in D.melanogaster (Canton strain) by exposing them to various concentrations of Tryptophan and Sodium fluoride. The control flies and the flies exposed to the different concentrations of Tryptophan and Sodium fluoride were observed for phenotypic changes after 24hours and 48hours of exposure. The DNA was isolated from all the flies and the quantity and quality of the DNA were checked using Nanodrop and DNA fragmentation assay respectively. Shearing was observed in all the concentrations of Tryptophan and Sodium fluoride, by DNA...

Database mining refers to extracting previously unrecognized information from data stored in conventional databases. Multimedia data mining deals with the extraction of implicit knowledge, multimedia data relationships, or other patterns not explicitly stored in multimedia databases. Three specific kinds of multimedia databases like image, video and remote sensed image are dealt with. A simple kind of multimedia database i.e., static image, where each mammogram is a set of four images is considered. Statistical analysis is performed on them to classify them as normal, benign and malign. Next...
