Nonlinear visco-hyperelastic constitutive relation for brain tissue with parametric sensitivity study
(1995)Biological tissues are known to be hyperelastic with strong viscous properties. Constitutive equations employing Mooney and Hart-Smith strain energy functions have been developed approximating brain as a thick hollow ... -
A chemical cell to estimate quantitatively haemoglobin and glucose by reflectance photometry
(1995)Presents the estimation of two important biochemical parameters-haemoglobin and glucose, quantitatively by a single chemical cell. The chemical cell has been so designed to be made of layers of cellulose matrix containing ... -
Solar drying and CO2 emissions mitigation: potential for selected cash crops in India
(2005)An attempt to estimate the potential of solar crop drying for some selected cash crops in India has been made. The amount of cash crops that can be dried by solar dryers and the required aperture area of solar dryers have ... -
Three-dimensional chitosan scaffold-based MCF-7 cell culture for the determination of the cytotoxicity of tamoxifen
(2005)Three-dimensional (3D) culture of cancer cell lines has long been advocated as a better model of the malignant phenotype that is most closely related to tumorigenicity in vivo. Moreover, new drug development requires simple ... -
Autofluorescence characterization of advanced glycation end products of hemoglobin
