A fully coupled computational fluid dynamics (CFD) and discrete element method (DEM) model was calibrated using a draw down test (DDT) under submerged conditions.Momentum smoothing and cell clustering were used to model particles that were larger than the cells.The DEM input parameter values were initially set equal to those calibrated for the dry
In the course of their missions or training, alpinists, but also mountain combat forces and mountain security services, professional miners, aircrew, aircraft and glider pilots and helicopter crews are regularly exposed to altitude without oxygen supplementation.At altitude, humans are exposed to systemic environmental hypoxia induced by the decrea
Schistosomes infect over 200 million people.The prodigious egg output of these parasites is the sole driver of pathology due to infection, yet our understanding of sexual reproduction by schistosomes is limited because normal egg production is not sustained for more than a few days in vitro.Here, we describe culture conditions that support schistos
