MANET is quickly spreading for the property of its capability in forming rapidly changing topologies network without the aid of any established infrastructure or centralized administration. The security challenges in MANET have become a primary concern to provide secure communication. The Attacks on MANET disrupts network performance and reliability. The(More)
In order to study effects of detergents at molecular level, we have done activity measurements of wheat germ lipase in increasing concentration of some commercial detergents. Conformational changes in protein structure using circular dichroism and fluorescence spectroscopy were studied in increasing concentration of sodium dodecyl sulfate. Our study proves(More)
A series of S-benzyl aryl thiourea were condensed with o-Methoxy phenyl isocyanate to yield respective isothiobiuret derivatives. The newly synthesized compounds were characterized by (1)H-NMR, IR, and Mass Spectral studies and tested for biological activities.
The objective of this study was to examine the effects of 2,2,2 trifluoroethanol (TFE) and acetonitrile (ACN) on the stability, behavior, and structural characteristics of giant multimeric protein Keyhole Limpet hemocyanin (KLH) by combining the circular dichroism (CD) and fluorescence measurements of KLH solution. In concentration range 20–50 % (v/v) TFE,(More)
To represent the three dimensional world around us, it is relevant to carry out 3D modeling and use 3D environment while portraying the Geographical data (geodata). Geographical data can be represented both in 2.5D and 3D environment. Geographic Information Systems (GIS) combined with 3D visualization technology is an emerging tool for urban planning and(More)
Without his guidance, this thesis would not have been possible, and I would have probably left Michigan after my second year. I consider myself very fortunate to have been able to learn how to use the circle method and pursue math research from Professor Wooley. I would also like to thank Donald Lewis for stepping in during my last year of graduate school(More)
