Abstract The rotating resistance of conveying belt accounts for the largest proportion running conveyor. To analyze key factors affecting its size, a simulation analysis relationship between conveyor load, idler diameter, speed, and indentation rolling was conducted based on finite element method. According to content, experimental verification carried out, test method formed. conclusions can p...

Problem. Rolling resistance is one of the most important operational characteristics a car tire. First all, fuel consumption, durability and service life tire depend on rolling resistance. Of course, higher resistance, faster more intensively will wear out. Also, braking parameters, such as deceleration and, accordingly, distance, may indirectly characteristics. In turn, influenced by propertie...

In this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % Si non-oriented electrical steel was investigated. For this purpose, all samples were processed through single-stage hot rolling at 1100 ° C and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °C for 35 seconds. Finally, all of them were fu...

Antibiotic resistance in bacterial pathogens poses an ever-increasing risk to human health. In antibiotic-resistant strains of Staphylococcus aureus this resistance often resides in extra-chromosomal plasmids, such as those of the pT181 family, which replicate via a rolling-circle mechanism mediated by a plasmid-encoded replication initiation protein. Currently, there is no structural informati...
