Steganography is the art and science of hidden writing. The purpose of steganography is covert communication to hide the existence of a message from an intermediate attacker .This paper will discuss about pure steganographic technique, which does not require prior exchange of data like shared-keys. The proposed technique use a secure mask generation(More)
Hematology of free-living Indian rhacophorid tree frog, Polypedates maculatus, was studied. Sex wise variations in the hematological values, as well as significant correlation between size and different hematological parameters, were observed in this species.
The present paper describes a sequential study of the leukocyte profiles and the changes in morphometry and morphology of erythrocytes in the tadpoles of Polypedates teraiensis during their development and metamorphosis, that is, transfer from an aquatic mode to a terrestrial mode of life. Blood smears of 21 different stages (Gosner stage 26 to 46) of(More)
With the rapid growth of communication/transaction over internet and continuous efforts by eavesdroppers or Cyber attackers, there is a continuous need for new strong alternative algorithm. Techniques for information hiding are becoming increasingly more sophisticated and widespread. The primary goal, for designing such algorithms, is to provide security.(More)
Emami Paper Mill Ltd. at Balgopalpur industrial area produces a huge amount of fly ash and waste water to the environment. The application of disposed fly ash and waste water in crop cultivation may reduce the problem to some extent. The aim of this study is to investigate the effects of direct land application of fly ash on plant growth and production of(More)
Blood was analyzed from eighty (forty males and forty females) adult individuals of Polypedates teraiensis to establish reference ranges for its hematological and serum biochemical parameters. The peripheral blood cells were differentiated as erythrocytes, lymphocytes, eosinophils, neutrophils, monocytes, basophils, and thrombocytes, with similar morphology(More)
