Effects of mechanical deformation on electric performance of rechargeable batteries embedded in load carrying composite structures

Integrating rechargeable battery cells with fibre reinforced polymer matrix composites is a promising technology to enable composite structures to concurrently carry load and store electric energy, thus significantly reducing weight at the system level. To develop a design criterion for structural battery composites, rechargeable lithium polymer battery cells were embedded into carbon fibre/epoxy matrix composite laminates, which were then subjected to tensile, flexural and compressive loading. The electric charging/discharging properties were measured at varying levels of applied loads. The results showed that degradation in battery performance, such as voltagea and energy storage capacity, correlated well with the applied strain under three different loading conditions. Under compressive loading, battery cells, due to their multilayer construction, were unable to prevent buckling of composite face sheets due to the low lateral stiffness, leading to lower compressive strength that sandwich panels with foam core.

Embedded library services : beyond chance encounters for students from low SES backgrounds

This paper reports research that examined how the embedding of library services through the learning management system contributed to the experience of students from low socio-economic status (SES) backgrounds. To evaluate the embedded practice, the researchers used a mixed-method approach involving surveys with students and interviews with library and academic staff. Survey results showed gains in students' awareness of library resources and in their confidence and satisfaction using them. Staff participants reported benefits to students from the improved visibility of the library and involvement of students in conversations about information literacy. The teacher derived personal benefits in learning more about digital information resources while library staff benefitted from the research-driven nature of the practice which strengthened their collaborative partnership with academic staff. Based on the evaluation, an embedded approach has been adopted at the university in additional courses which have similar student profiles. The outcomes are relevant more widely in demonstrating both the potential benefits of embedded practice for supporting diverse student populations and how libraries can target their activities more effectively to national and university agendas for improving student outcomes.

Embedded in the land: customary social relations and practices of resilience in an East Timorese community

Drawing on a case study of Cacavei, a rural subsistence community in Timor-Leste, this article explores the mutually constitutive relationship between people and land within customary forms of society. Patterns of land use and connection to land are not simply reflective of genealogical modes of social organisation, but are also enabling of them. Particularly, the embedding of ancestors within the land offers a means of accessing kinship relationships beyond the genealogical present. Embeddedness provides a quality of embodiment that makes ancestors active participants in social life. Constituted in the relational nexus of people and land, forms of social organisation in Cacavei have a mutability which goes some way to explaining the community’s resilience in spite of forced displacement and cultural disruption during the period of Indonesian occupation. This mutability might be considered more broadly as a source of resilience for customary communities grappling with modernising processes of change.
