The effects of lapping load in finishing advanced ceramic balls on a novel eccentric lapping machine
, 2005 HIPed (Hot Isostatically Pressed) silicon nitride ball blanks were lapped from diameter 13.255 mm to diameter 12.7 mm by a novel eccentric lapping machine. A maximum material removal rate of 68 μm/hour has been achieved under a nominal lapping load of 43

Otherwise engaged? Learning from non‐participation in research with care‐experienced students
British Educational Research Journal, EarlyView.Abstract This paper explores what can be learned when educational research “fails.” Drawing on a Welland Trust–funded project in the North East of England that aimed to support care‐experienced students transitioning from further to higher education, we reflect on why, despite sustained effort, there was a lack of engagement.
