Data Security Using Cryptosteganography in Web Application
Data security using Cryptosteganography in web application is a web based application used to conceal important information through hybrid cryptography and Steganography and provide means of its secure transmission through any medium or channel .Using a web browser the user uploads the important information and an envelope image. The same is received by the Data Shielder facade web application .The web application sends the data and envelope image to the real Data Shielder .It generates a unique key and encrypts the crucial data .The key is associated with a "unique id" and preserved in a store .Then the encrypted information is embedded into the envelope image using modified BPCS technique .Finally a stego image is generated .Data Shielder returns the "unique id" and stego image to the facade web application .Web application further archives the stego image and unique key and allows the user to download it. The user can simply unzip the archive and transmit the stego image through unsecured channels like email, sockets, pen drives, cds, dvds, etc. And can keep the unique id safe. When the user wants its data back then user needs to upload the stego image and the "unique id" to the Data Shielder facade web application. The web application sends the unique id and stego image to the real Data Shielder. First it finds the encryption key from the store through the unique id. Next, reversing the BPCS Steganography, the stego image is processed and encrypted data is fetched. Finally using the encryption key decryption is done and the crucial data is fetched back. The same is returned to the facade web application, which is rendered to the user. Keywords: Cryptography, Steganography, Stego- image, Threshold Valu
Anti-Inflammatory and Antioxidative Stress Effects of Oryzanol in Glaucomatous Rabbits
Purpose. γ-Oryzanol works by anti-inflammatory and radical scavenging activity as a neuroprotective, anticancer, antiulcer, and immunosuppressive agent. The present study was conducted to investigate effect of oryzanol in acute and chronic experimental glaucoma in rabbits. Methods. Effect of oryzanol was evaluated in 5% dextrose induced acute model of ocular hypertension in rabbit eye. Chronic model of glaucoma was induced with subconjunctival injection of 5% of 0.3 ml phenol. Treatment with oryzanol was given for next two weeks after induction of glaucoma. From anterior chamber of rabbit eye aqueous humor was collected to assess various oxidative stress parameters like malondialdehyde, superoxide dismutase, glutathione peroxidase, catalase, nitric oxide, and inflammatory parameters like TNF-α and IL-6. Structural damage in eye was examined by histopathological studies. Results. In acute model of ocular hypertension oryzanol did not alter raised intraocular pressure. In chronic model of glaucoma oryzanol exhibited significant reduction in oxidative stress followed by reduction in intraocular pressure. Oryzanol treatment reduced level of TNF-α and IL-6. Histopathological studies revealed decreased structural damage of trabecular meshwork, lamina cribrosa, and retina with oryzanol treatment. Conclusions. Oryzanol showed protective effect against glaucoma by its antioxidative stress and anti-inflammatory property. Treatment with oryzanol can reduce optic nerve damage

Not AvailableMaize (Zea mays L.) is one of the most versatile cereal crops and widely cultivated in more than 150 countries of the world including tropical and temperate regions. Though maize can be grown in the wide range of climatic conditions, its productivity is largely depending on the prevailing weather conditions throughout the life cycle of the crop. Different management practices as well as prevailing weather parameters affect growth and development of crop differently. Therefore, it was contemplated to have an insight on the effect of photosynthetically active radiation (PAR) interception and leaf area index of maize grown under
different nutrient management practices in Punjab.Not Availabl
A new species of Psephenothrips (Thysanoptera:Phlaeothripidae) with one new record from India

Phase behaviour and physicochemical study of Karanj oil-ethanol microemulsion as alternative renewable biofuel
461-464Vegetable oil reverse micelle microemulsions as an
alternative method for biodiesel production has been studied to eliminate transesterification
reaction and avoid unpurified glycerol formation. The sorbitane oleate ester
surfactants due to high solubilization capacity in oils have formed reverse
micelle microemulsions with karanj oil and ethanol. The phase behaviour of span
80 and 85 based Karanj oil-ethanol microemulsion have been studied with their
physicochemical parameters i.e. density and viscosity for formulating optimized
systems as biofuel. The kinematic viscosity being an important physicochemical
parameter elucidate karanj oil-ethanol microemulsion a better biofuel with span
80 than with span 85 as their
resultant viscosities were in close agreement with ASTM biodiesel standards. It
has been found that the microemulsification is a
sustainable method for producing biofuels without chemical reactions as green
fuel. </i

Not AvailableExperiment conducted on post-harvest utilization of date palm fruits of
cultivar Khadrawy at doka maturity stage for development of dehydrated
fruits at three different duration of days i.e. 5, 7 and 9days through inclined
solar drier revealed that solar dehydration of the whole date fruits with
increased duration of nine days led to the development of the dehydrated
product with significant different for minimum physiological loss in weight
(46.2%) and maximum recovery percentage (53.8%). However, on
biochemical parameter the retention of quality of total sugar (52.1%),
reducing sugar (2.7%) and Non reducing sugar (49.3%) was found
significantly different when fruits were dried with minimum duration for
five days. Organoleptic test by hedonic scoring revealed that the average
scoring by the panels ranged from like slightly (6) to like very much (8) for
color, flavour, texture and taste in the dehydrated fruits.Not Availabl
