Exploratory flutter test in a cryogenic wind tunnel [PDF]
A model consisting of a rigid wing with an integral, flexible beam support that was cantilever mounted from the wall in the NASA LaRC 0.3-m transonic cryogenic tunnel was used in a flutter analysis study.

Influence of renewable energy trends on fossil fuel refining operations
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study examines how renewable energy indicators such as biofuel prices, biofuel integration, electrification, and carbon allowance prices relate to refined fuel production in Portugal’s refining sector. This is set against the backdrop of the sector’s decarbonization efforts and the economic pressures to meet European Union climate targets.

British Educational Research Journal, EarlyView.Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Experimental transonic flutter characteristics of two 72 deg-sweep delta-wing models [PDF]
Transonic flutter boundaries are presented for two simple, 72 deg. sweep, low-aspect-ratio wing models. One model was an aspect-ratio 0.65 delta wing; the other model was an aspect-ratio 0.54 clipped-delta wing.

Transforming the Manufacturing Sector Towards Circular Economy—A Configurational Approach
Business Strategy and the Environment, EarlyView.ABSTRACT Despite growing awareness of—in principle—easily transferable circular economy (CE) best practices, their adoption remains limited. As scholarly discourses on CE and operations management concentrate on linear construct relations, the complex interdependence of practices and their determinants is overlooked.
