Operating characteristics of heavy loaded cylindrical journal bearing with variable axial profile
Materials Research, 2005 During the operation of turbounit its bearings displace as a result of heat elongation of bearings supports. It changes the static deflection line of rotor determined during assembly of the turbounit, causing an increase in the stresses on the bearing ...

Influence of Micropolar Lubricants on Asymmetric Slot-Entry Journal Bearings
Tribology Online, 2015 Performance of asymmetric slot-entry hydrostatic and hybrid journal bearings lubricated under micropolar lubricant has been presented numerically. For chosen values of microploar parameters, the effects of micropolar lubricant on both the bearings have ...

Why human connection is the true metric of research success
FEBS Open Bio, EarlyView.Human‐centred mentorship can be shaped by mentor attributes, actions, intrinsic drive and career ambition. Drawing on reflections across Singapore and France, as well as workshop insights from FEBS‐IUBMB ENABLE 2024, this article shows that human‐centred mentorship creates the conditions for sustainable growth, well‐being and retention in research ...
