Wear Simulation with a Focus on Mild Wear in Rolling and Sliding Contacts
, 2011 The amount of wear occurring in high-performance rolling and sliding contacts is often quite small, and such contact surfaces often become glossy. To obtain good contact conditions, it is necessary that the form and the topography of the surfaces be good,

Influence of hardness of the harder body on wear regime transition in a sliding pair of steels
, 2009 In the unlubricated sliding wear of steels the mild-severe and severe-mild wear transitions have long been investigated. The effect of system inputs such as normal load, sliding speed, environment humidity and temperature, material properties, among ...

TED1 Promotes the Assembly of SCFD3‐D14‐D53 to Reinforce Strigolactone Signaling in Rice
Advanced Science, EarlyView.This study identifies TED1 as a positive regulator of strigolactones (SL) signaling in rice. The ted1 mutants display dwarfism and increased tillering with significantly reduced SLs sensitivity. Through its longer C‐terminal region, TED1 interacts with D53 and D14 to promote the assembly of SCFD3‐D14‐D53, thereby facilitating the efficient ...
