Flocculation treatment processes play an important role in water and wastewater pretreatment.Here we investigate experimentally and theoretically the possibility of using graphene oxide (GO) as a flocculant to remove methylene blue (MB) from icon track bar f250 water.Experimental results show that GO can remove almost all MB from aqueous solutions
In order to study the longitudinal impulse problem on 20 000 t heavy haul combined train in China, the kinetic model ofcombined train with an example of coal dedicated gondola car of C80 series was established by Matlab/Simulink module.It was mainlyanalyzed that effects of longitudinal impulses under emergency braking conditions for combined train
Traction failure on loose terrain is common in conventional agricultural wheeled tractors due to poor traction ability and lower power transfer efficiency of drive wheels, which leads to excessive energy consumption and soil compaction in agriculture.To overcome the problem, this paper presents a new design of a rigid lugged wheel for use in field
