Web16 mrt. 2024 · As requested by the Ministry of Manpower, the ILO provides a two-day training session on industrial relations to strengthen the capacity of the Manpower Ministry’s Development Centre of Human Resources to be more adaptive with the fast changing world of work and emerging industrial relations issues. WebStrengthening with fine particles can produce a planar-to-wavy or wavy-to- planar slip mode transition depending on the nature of the dislocation-particle interactions. Particles which are sheared by dislocations tend to produce slip which is coarse and planar. Particles which are bypassed by dislocations lead to fine wavy slip.
