At ambient temperature, concrete exhibits excellent mechanical properties. However, understanding the behavior of under high-temperature conditions is crucial, especially for civil engineering applications during fire incidents. The growing use plastic-based products has led to a significant increase in polymer waste, posing environmental challenges. valorization this plastic waste form fibers ...

Introduction: In contemporary THA there are two broad approaches to acetabular cup design and materials. One is an all-polyethylene design with polymethylmethacrylate (PMMA) cement. PMMA possesses a modulus of elasticity of about 2 GPa, which is between that of trabecular and subchondral bone. The second more popular approach, especially for active, younger patients, is the porous metal-backed ...
