Infrastructures of power: Governance by energy systems and infrastructure
First MondayThis paper suggests a synthetization of three classic approaches to analyze infrastructures as interconnected compositions that subtly distribute power and governance. We draw upon conceptualizations within large technological systems (LTS), Internet governance, and information infrastructures (II), and connect them to our own extensive research in ...

Infrastructure Networks in Central Europe and EU Enlargement [PDF]
, 2003 This paper draws attention to the spatial dimension of sustainability, where spatial self-defence is an important part of control over local assets that have to be preserved.

Advanced Engineering Materials, EarlyView.This study investigates innovative thermoreversible hydrogels derived from S53P4 bioactive glass extracts to aid in the healing of infected diabetic foot wounds. These injectable gels, which gel at body temperature, release beneficial ions and remain stable over time.

Towards a Co-Evolutionary Model of Demographics and Infrastructure [PDF]
, 2015 National infrastructure systems provide a foundation for economic prosperity and well-being. In addition to factors such as technological change and obsolescence, infrastructure systems need to respond to changing levels of demand, which is strongly ...

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Advanced Engineering Materials, EarlyView.Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.

Infrastructure, market access, and agricultural prices [PDF]
The effect of recent agricultural market reforms in many developing countries is often measured through tests for market integration by analyzing co-variation of food prices.

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
