Semi-flexible concrete has been utilized in highway engineering due to its exceptional pavement performance.This study investigates the proportions of semi-flexible grout, the porosity of asphalt mixture, and the performance of semi-flexible concrete.Initially, 18 sets of semi-flexible grouting materials were proposed through an orthogonal test, re

Abstract Background Activated sludge (AS) systems in wastewater treatment plants (WWTPs) harbor enormous viruses that regulate microbial metabolism and nutrient cycling, significantly influencing the stability of AS systems.However, our knowledge about the diversity of viral taxonomic groups and functional traits in global AS systems is still limit

This paper explores the implementation and possibilities of utilizing fuzzy logic theory for optimal operation and color depositing mask early fault detection in marine diesel engines.It emphasizes its role in managing the complexity and ambiguity inherent in engine performance and preventive maintenance.Preventive maintenance is crucial for ensuri
