Business Strategy and the Environment, EarlyView.ABSTRACT Firms increasingly commit to climate targets yet doubts remain about whether such pledges translate into substantive corporate governance or remain symbolic. The study examines how emission reduction targets (ERTs) in sustainability strategies are reflected in compensation among German listed firms.

Business Strategy and the Environment, EarlyView.ABSTRACT The inefficiencies of the global food system necessitate a shift towards a circular economy (CE) in food supply chains (FSCs). While research on CE in FSCs spans multiple disciplines, it often remains siloed within respective disciplinary boundaries, limiting its practical impact.

FlexMat, EarlyView.In this work, we first examine the limitations of surgical repair and stenting, including migration, granulation, mucus plugging, and infection. We then translate these failures into engineering constraints involving geometry, mechanics, fixation, degradation, junctional stress, and remodeling.

Ceramics for Aero-Engine Applications [PDF]
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education, 1992 In the general aero-engine development effort to significantly improve specific fuel consumption as well as thrust-to-weight ratios, ceramics have been under investigation since the mid-Seventies. Their great potential for increasing gas-turbine performance has resulted in a number of research programs worldwide to assess their desirability for static ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...
