Connecting Industry 4.0, Servitisation and Sustainability: Territorial Implications for Global Value Chains

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Globalisation has deepened the integration of international production within global value chains (GVCs), where the various stages of the manufacturing process are dispersed across countries. In today's volatile business environment, characterised by rapid technological advances (Industry 4.0) and evolving consumer preferences towards use ...

Circular Economy Pathways for Airport Climate Change Mitigation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...

Flight investigation of the VFR and IFR landing approach characteristics and terminal area airspace requirements for a light STOL airplane [PDF]

open access: yes
A flight research program was conducted to determine the terminal area instrument flight capabilities of a light STOL airplane. Simulated (hooded) instrument landing approaches were made using steep single-segment and two-segment glide slopes.

Harnessing Carbon‐Containing Materials for Next‐Generation High‐Temperature Electromagnetic Wave Absorbers

open access: yesCarbon Energy, EarlyView.
Traditional carbon materials show limited high‐temperature oxidation resistance, which becomes pronounced above 673 K and significantly restricts their practical applicability. To address this challenge, enhancing polarization loss and leveraging its negative temperature dependence to offset the temperature‐induced increase in conductance loss are ...
