Abstract

Expressions involving products of exponential functions and polynomials are encountered in the finite element formulation of the diffusion‐convection equation. Integrals of such expressions over finite elements are necessary to derive the element matrices. The derivation of the formula for such integrations is presented.

While human malignant mesothelioma is extremely resistant to chemotherapy, its intrinsic resistance mechanisms remain largely unknown. In this study, we used normal human mesothelial cells and 5 human mesothelioma cell lines not previously exposed to chemotherapeutic agents to demonstrate that the m
