Abstract: Geotechnical subgrade preparation for high-consequence structures, such as nuclear power plants (NPPs) and Small Modular Reactors (SMRs), represents one of the most demanding disciplines in civil engineering due to the extreme structural loads and safety margins involved. This state-of-the-art review paper bridges two traditionally distinct domains: micro-scale material chemistry of sustainable soil stabilizers (Pillar I) and macro-scale structural Soil-Structure-Foundation Interaction (SSFI) under dynamic seismic excitation (Pillar II). Deep Soil Mixing (DSM) is evaluated as the critical, multiscale physical-chemical interface connecting these disciplines....

Abstract: Storage tanks are critical components in industrial facilities because their failure can interrupt operations and generate safety and environmental consequences. This study presents a parametric assessment of the structural response of a fixed-roof cylindrical storage tank subjected to internal pressure. A three-dimensional model based on the available.....

Abstract: Premixed combustion has attracted considerable attention due to its high thermal efficiency, stable combustion characteristics, and potential for reducing pollutant emissions. The present study experimentally investigates the effect of equivalence ratio on confined premixed LPG–air flames stabilized by a bluff-body flame holder. Experiments are conducted over an equivalence ratio of 0.8–1.2 while maintaining a constant blockage ratio, confinement ratio, and fuel.....
