We study heat rectification in composition-graded nanowires. with nonlocal and nonlinear effects taken into account in a generalized Guyer-Krumhansl equation. Using a thermal conductivity dependent on composition and temperature. the heat equation is solved. https://www.nacrack.com/amazing-price-1997-2000-BMW-528I-Front-Bumper-Reinforcement-Bar-Used-Original-Exterior-OEM-great-save/
