The present work investigates the problem of a cylindrical crack in a functionally graded cylinder under thermal impact by using the non-Fourier heat conduction model.The theoretical derivation is performed by methods of Fourier ice blue graphic tee integral transform, Laplace transform, and Cauchy singular integral equation.The concept of heat flu
This paper presents a multi-objective mathematical model for the reverse supply chain of hospital waste management in Iran during the COVID-19 pandemic, incorporating dimensions of sustainability.The objectives of the model are as follows: 1) Minimizing the costs associated with building facilities and waste treatment centers, vehicle fuel costs, a
This study investigates the thermal shrinkage behavior of cold-drawn or necked crystalline polymer solids through a mathematical framework of catastrophe theory.While polymers necked by uniaxial stretching exhibit irreversible macroscopic plastic deformation, they demonstrate significant shape-memory recoverability upon thermal treatment.A phenomen
AIM: To explore the functions of Chordin-like 2, which is encoded by CHRDL2, in the process of retinal pigmented epithelium (RPE) differentiation and damage repair.METHODS: The fetal RPE cells (fRPE) was obtained from aborted fetus which obeyed medical ethics.Real-time quantitative polymerase chain reaction was used to measure expression quantity o
The present work addresses a decentralized, well tested three-area multi-unit power system for its automatic generation control (AGC) after deregulation which is characterized by price-based market operation.To match with the actual deregulated environment, as prevailing in the real one, the market structure is kept generic enough enabling to captu
