Grinding-wheel wear is a critical factor affecting grinding performance and tool cost. Unfortunately, tests – particularly with superabrasives can be notoriously time-consuming. Therefore, novel lapping-based method proposed for investigating behaviour of the grit-bond system. Wear were performed in (i) lapping, (ii) surface grinding, (iii) cylindrical range grit-shape aspect ratios grit-toughn...

Abstract Despite its popularity in practice, the Grit-O Scale has shown inconsistent factorial structures and differing levels of internal consistency samples outside USA. The validity different contexts is, therefore, questionable. As such, purpose this paper was to determine whether could be used as a valid reliable measure compare grit across nations. Specifically, aim investigate validity, ...

Research has revealed that perceived discrimination may be a risk factor against school adjustment among Chinese migrant children.

Grit is a positive noncognitive ability that has been associated with social outcomes and improved mental health. To address the research gap in Japan regarding temporal stability of grit, three-year longitudinal survey (T1: N=1,087–T3: N=546) was conducted among caregivers. The study aimed to determine whether grit stable personality trait. also compared change scale scores correlations those ...

The role of the nucleus basalis prosencephali (Bas), a frontal forebrain structure peculiar to birds, in the control of forage pecking and apomorphine-induced pecking was investigated. In a quasi-natural grit-grain selection task bilateral coagulations of the Bas and the associated neostratum frontolaterale (Nfl) caused a marked fall in grain per peck uptake and a simultaneous increase in grit ...
