The impact of buckling containment features on the stability of thin-gauge fuselage, metallic stiffened panels has previously been demonstrated. With the continuing developments in manufacturing technology, such as welding, extrusion, machining, and additive layer manufacture, understanding the benefits of additional panel design features on heavier applications, such as wing panels, is timely. This compression testing of thick-gauge panels with and without buckling containment features has been undertaken to verify buckling and collapse behaviors and validate sizing methods. The experimental results demonstrated individual panel mass savings on the order of 9%, and wing cover design studies demonstrated mass savings on the order of 4 to 13%, dependent on aircraft size and material choice.

This study describes an investigation into the characteristics, needs and experiences of kinship foster carers in Northern Ireland. By adopting a mixed-methods approach with 54 carers, a number of salient themes was captured. The respondents were predominantly grandparents who experienced a significant incidence of health-related issues. The cohort also endured high levels of stress, particularly at the beginning stage of the foster placement. Consequently, their need for practical, emotional and respite support was most evident. In terms of the children for whom they cared, many required help at school, and some presented with challenging emotions and behaviours. Overall, these findings emphasised the importance of relationship-based social work and demonstration of accurate empathy to the carer.
