We derive Godunov-type semidiscrete central schemes for Hamilton–Jacobi equations on triangular meshes. High-order schemes are then obtained by combining our new numerical fluxes with high-order WENO reconstructions on triangular meshes. The numerical fluxes are shown to be monotone in certain cases. The accuracy and high-resolution properties of our scheme(More)
Metals and minerals are used profusely in practice of Ayurveda after proper incineration by the name of Bhasma. Some metals and minerals have the potency to produce toxic effects in human being. In this paper safety and toxicity profiles of Tamra Bhasma (incinerated copper, Cu), Lauha Bhasma (incinerated iron, Fe), and Yashada Bhasma (incinerated Zinc, Zn)(More)
