Now an afternoon's cloud computing is used in lots of areas like industry, military schools etc to storing large amount of statistics. We are able to retrieve facts from cloud on request of person. To shop records on cloud we should face many troubles .To offer the answer to those troubles there are n wide variety of ways .Cryptography and steganography techniques are more popular now a day's for facts safety. Use of a unmarried algorithm isn't effective for high degree safety to data in cloud computing. On this paper we have introduced new security mechanism the usage of symmetric key cryptography set of rules and steganography .in this proposed gadget AES set of rules are used to offer block sensible safety to records. This set of rules key length is 128 bit.. LSB steganography method is introduced for key information security. Key statistics includes which part of file is encrypted the usage of by which set of rules and key .file is splited into 8 parts. Each and each a part of record is encrypted using extraordinary set of rules. All parts of file are encrypted concurrently with the assist of multithreading technique. Records encryption Keys are inserted into cowl photo the use of LSB approach. Stego picture is ship to valid receiver the use of e-mail .For record decryption reason opposite manner of encryption is applied.

The aim of present investigation was to develop press coated tablet for pulsatile drug delivery of Salbutamol sulphate using hydrophilic and hydrophobic polymers. The drug delivery system was designed to deliver the drug at such a time when it could be most needful to patient of rheumatoid arthritis. The press coated tablets containing Salbutamol sulphate in the inner core was formulated with an outer shell by different weight ratio of hydrophobic polymer (micronized ethyl cellulose powder) and hydrophilic polymers (Glycinemax Husk or sodium alginate). The release profile of press coated tablet exhibited a lag time followed by burst release, in which outer shell ruptured into two halves. Authors also investigated factors influencing on lag time such as particle size and viscosity of ethyl cellulose, outer coating weight and paddle rpm. The surface morphology of the tablet was examined by a scanning electron microscopy. Differential scanning calorimeter and Fourier transformed infrared spectroscopy study showed compatibility between Salbutamol sulphate and coating material.
