Different Employment of Capitals in Vertically Integrated Sectors: Smith after the Austrians [PDF]
The Austrian notion of stages of production and the related principle of the greater productivity of roundabout methods plus the neo-Austrian notions of vertical integration and vertical division of labour are utilized in this paper in an attempt to ...

A hybrid system for de‐icing made of gradient polymer coatings, deposited on aluminum coupled with an electromechanical system, is demonstrated as an effective and durable strategy for reducing drastically ice adhesion. The system is capable of detaching ice blocks over the coating in less than 1 s, regardless of the ice type and covered area ...

Influence of Form and Structural Features of Open‐Cell Hybrid Foam on the Remanent Magnetic Scanning
Simulations using an equivalent model are performed to improve the understanding of remanent magnetic scanning of hybrid foam samples for coating thickness estimation. The model allows to study the influence of isolated geometrical features such as layer thickness, boundary effects, as well as effects due to the statistical nature of the foams, which ...
