We study the minimality of an isometric immersion of a Riemannian manifold into a strictly pseudoconvex CR manifold M endowed with the Webster metric (associated to a fixed contact form on M), hence formulate a version of the CR Yamabe problem for CR manifolds-with-boundary. This is shown to be a nonlinear subelliptic problem of variational origin.

the purpose of this work was to develop once daily sustained release (sr) matrix tablets of naproxen, an anti-inflammatory agent. the tablets were prepared by wet granulation method along with hydrophilic matrix materials like methocel k 15m cr and methocel k 100m cr. the granules were evaluated for bulk density, angle of repose, compressibility index, total porosity and drug content. the table...

Electrodeposition is a simple and economic technique for precision coating of different shaped substrates with pure metal, alloy or composite films. Dc electrodeposition was used to produce Cr, Co-Cr and Co-Cr/TiO2 nano-composite coatings from Cr(III) based electrolytes onto 316L SS substrates. The effects of TiO2 nanoparticles concentration on co-deposition of these particles along with Cr con...
