In this paper, the authors have presented a robust watermarking scheme which employs both the Discrete Cosine Transform (DCT) and the Singular Value Decomposition (SVD). The proposed scheme starts with transformation of an original grayscale cover image into a transformed image using block based DCT. From each transformed block, the middle band DCT(More)

During cell division, a microtubule-based mitotic spindle mediates the faithful segregation of duplicated chromosomes into daughter cells. Proper length control of the metaphase mitotic spindle is critical to this process and is thought to be achieved through a mechanism in which spindle pole separation forces from plus-end-directed motors are balanced by(More)
During cell division, a mitotic spindle is built by the cell and acts to align and stretch duplicated sister chromosomes before their ultimate segregation into daughter cells. Stretching of the pericentromeric chromatin during metaphase is thought to generate a tension-based signal that promotes proper chromosome segregation. However, it is not known(More)
Chemical separation has great importance in industrial applications. Separation of xylene isomers still prevails to be one of the most important challenges in chemical industry, due to the large amount of commercial use of p-xylene in the production of beverage bottles, fibers and films. A novel Zn(II)-based dynamic coordination framework based on flexible(More)
Lupus vulgaris is a chronic paucibacillary form of cutaneous tuberculosis occurring in a person with a moderate to high degree of immunity. It commonly occurs over the buttocks and trunk in India. Involvement of the genitalia is uncommon, and lesions involving the penis, extremely rare with few cases reported worldwide. There also exists a confusion(More)
Subcutaneous Zygomycosis is a rare opportunistic fungal infection caused by Basidiobolus ranarum. Though this entity is endemic in South India, limited numbers of cases have been reported from this part of the country. We report a case of subcutaneous zygomycosis in a 25 year old lady who presented with a nontender, firm to hard swelling over the upper-left(More)
The possible protective role of ethanolic extract of A. indica tuber (EEAIT) in hepatotoxicity and apoptosis of liver caused by alcohol in rats was investigated. Treatment of rats with alcohol (3 g ethanol per kg body weight per day for 15 days intraperitoneally) produced marked elevation of liver biomarkers such as serum alanine aminotransferase (ALT),(More)
Serotonin (5-HT) is an essential neurotransmitter for cognitive functions and formation of new memories. A deficit in 5-HT dependent neuronal activity is somewhat specific for Alzheimer’s disease. Metal-mediated oxidative degradation of neurotransmitters by Aβ bound to metals has been investigated. Heme-bound Aβ is found to catalyze the oxidative(More)
Extracellular cellobiase activity of Termitomyces clypeatus increased from 2.9 U ml−1 to 4.4 and 4.1 in presence of dithiothreitol (DTT) and β-mercaptoethanol (ME), respectively, with a decrease in Km from 0.4 to 0.3 mM (DTT) and 0.35 mM (ME). Catalysis was further enhanced if the reduced enzyme was alkylated and activity increased from 11.4 U ml−1(More)
