The dust explosion prevention in mines and dusted industries has been an important issue for years. During this time, many experimental and theoretical investigations have been carried out. Nevertheless, up to now nobody can declare that all the mechanisms are clear and the comprehensive mathematical model is constructed taking into account all the details of this complicated process. The gas-d...

BACKGROUND July 2006 was the first major heat wave in France after the creation of a heat prevention plan. Understanding its impacts on health will help improving the efficiency of this plan. We assessed the mortality impact of the heat wave, and investigated the influence of the heat prevention plan. METHODS The study focused on nine French cities. A Poisson regression model was used to anal...

In this work, we follow the idea of the De Broglie’s matter waves and the analogous method that Schrödinger founded wave equation, but we apply the more essential Hamilton principle instead of the minimum action principle of Jacobi which was used in setting up Schrödinger wave equation. Thus, we obtain a novel non-relativistic wave equation which is different from the Schrödinger equation, and ...

A theoretical model of action potential propagation in a thick strand of cardiac muscle is presented. The calculation takes into account the anisotropic and syncytial properties of the tissue, the presence of the interstitial space, the effect of the surrounding tissue bath, and the variation of the potential both along the strand length and across the strand cross section. The bidomain model i...
