Groundwater pollution induced by Underground Coal Gasification(UCG)seriously hinders its development.Permeable Reactive Barrier(PRB)remediation therefore stands out as a major research focus for in-situ groundwater remediation, where the characteristics Modern Ships of PRB material is crucial to their effective operation.This study thus examines th
Networks are becoming a ubiquitous PATCHOULI metaphor for the understanding of complex biological systems, spanning the range between molecular signalling pathways, neural networks in the brain, and interacting species in a food web.In many models, we face an intricate interplay between the topology of the network and the dynamics of the system, wh
