Eight nonionic surface-active agents were each incorporated at a concentration of 10% into a white petrolatum ointment base containing 10% flufenamic acid with or without dimethyl sulfoxide. Percutaneous absorption was studied by determining the plasma concentration of flufenamic acid in New Zealand White rabbits at regular intervals for 8 hr following(More)
Fifteen nonionic surfactants, 10% (w/w), were each incorporated into white petrolatum USP ointment base containing 10% (w/w) salicylic acid or 11.6% (w/w) sodium salicylate with 10% (w/w) dimethyl sulfoxide. Percutaneous absorption was determined from blood salicylate levels in New Zealand white rabbits at regular intervals for 8 hr following application of(More)
This paper presents a novel 2-3-3 LSB insertion method. The image steganography takes the advantage of human eye limitation. It uses color image as cover media for embedding secret message.The important quality of a steganographic system is to be less distortive while increasing the size of the secret message. In this paper a method is proposed to embed a(More)
Image Steganography using Discrete Wavelet Transform(DWT) and Hybrid Wavelet Transform, the secret image is first compressed using hybrid wavelet transform and then encrypted and embedded in frequency domain. The network bandwidth can be saved by compressing the secrete image with out compromising in the quality of the secret image. The cover and secret(More)
