Circling the Archetype: Tensions Limiting the Transformation to a Circular Economy
ABSTRACT This research examines key tensions and the archetypal paradox that prevent the transformation to a circular economy (CE) across individual, organizational, and systems levels, problematizing CE assumptions. Tension manifestations are analyzed using a qualitative case study across eight diverse industries and geographies.

ABSTRACT Circular innovation (CI) research has identified a wide range of circular strategies and design approaches, yet offers limited insight into how CI evolves as a learning process within firms and which governance mechanisms guide this progression. Drawing on organizational learning (OL), this study examines how exploration and exploitation shape

Bifurcation analysis of nose landing gear shimmy with lateral and longitudinal bending [PDF]
We develop and study a model of an aircraft nose landing gear with torsional, lateral and longitudinal degrees of freedom. The corresponding three modes are coupled in a nonlinear fashion via the geometry of the landing gear in the presence of a nonzero ...

Research Progress in Gear Steels for High Temperature Carburization
The carburizing temperature of common gear steels is 930 °C, as the carburizing temperature of steel increases to 1 000 ~ 1 050 °C the time of carburization process can be remarkably reduced but it easily leads to grain coarsening.

Analysis of the Regulatory Framework for the CCU Technology
ABSTRACT Carbon capture and utilisation (CCU) is increasingly considered an important technology for achieving climate neutrality within the German and European legal framework. Recent developments, particularly the Carbon Dioxide Storage and Transport Act (KSpTG), aim to enable CO2 transport infrastructure and cross‐sector carbon management systems ...
