ANALYSIS OF INFLUENCING FACTORS OF PNEUMATIC FLOW ENHANCEMENT OF PUMPED CONCRETE BASED ON DISCRETE ELEMENT METHOD

Analysis of influencing factors of pneumatic flow enhancement of pumped concrete based on discrete element method

It is known that, long-distance concrete pipeline transportation Slicing and Carving Knives often causes pipe blocking accidents.For the problem of pipeline blockage, we have invented a swirl speed-increasing device.In this study, the discrete element method was used to calibrate the parameters of the contact model through the slump bucket experime

The Legionella genus core effectors display functional conservation among orthologs by themselves or combined with an accessory protein

The intracellular pathogen Legionella pneumophila, as well as other Legionella species, utilize the Icm/Dot type-IV secretion system to translocate an exceptionally large and diverse repertoire of effectors into their host cells.However, only nine core effectors were found to be present in all analyzed Legionella species.In this study, we investiga
