Effect of solute content and temperature on the deformation mechanisms and critical resolved shear stress in Mg-Al and Mg-Zn alloys

The influence of solute atoms (Al and Zn) on the deformation mechanisms and the critical resolved shear stress for basal slip in Mg alloys at 298 K and 373 K was ascertained by micropillar compression tests in combination with high-throughput processing techniques based on the diffusion couples. It was found that the presence of solute atoms enhances the size effect at 298 K as well as the localization of deformation in slip bands, which is associated with large strain bursts in the resolved shear stress ($\tau_{RSS}$)-strain ($\epsilon$) curves. Deformation in pure Mg and Mg alloys was more homogeneous at 373 K and the influence of the micropillar size on the critical resolved shear stress was much smaller. In this latter case, it was possible to determine the effect of solute content on the critical resolved shear stress for basal slip in Mg-Al and Mg-Zn alloys

Positive parenting support during family reunification

This article presents the results of a qualitative study that explores parenting skills when a child returns home after a period of foster care in the child protection system. There were a total of 135 participants, including 63 child protection professionals, 42 parents and 30 children and adolescents. The data were analysed using content analysis submitted to peer review. Triangulating the voices of children with the input of parents and professionals rendered it possible to identify needs for the consolidation of family reunification in five dimensions: adjustment of parenting skills, adaptation to the needs of the child, social support, more accurate perception of one's role, and parental self-efficacy. These findings suggest particular characteristics in the development of both generally applicable skills and skills specific to positive parenting that can improve the chances of a successful reunification process
