Abstract Aquifer storage and recovery systems using multiple partially penetrating wells (MPPW-ASR) can form a viable solution to the problem of freshwater buoyancy when brackish aquifers for storage. This study presents result series laboratory experiments that aimed at visualizing shape bodies injected into aquifer determining effect on efficiency (RE) several MPPW-ASR operational variables. ...

Background: Crohn’s disease is a heterogeneous entity. Disease behaviour, characterised as stricturing, penetrating, or non-stricturing non-penetrating, is a clinically important phenotype as it is associated with complications and need for surgery.
