Behaviour Comparison Between Mechanical Epicyclic Gears and Magnetic Gears [PDF]

, 2017
This article deals with the magnetic gears with modulating ring and mechanical epicyclic gears and their operation. A power transmission analysis is done and permits to obtain an analogy of the kinematics between the two gear systems. Moreover, a transposition of the mechanical epicyclic gear arrangements to a magnetic gear arrangements can be made ...

Alkali‐Catalyzed Synthesis of Acylglycerol Estolides Exclusively from Castor Oil

Journal of the American Oil Chemists' Society, EarlyView.
This work advances sustainable chemistry by converting renewable castor oil into high‐performance estolides via solvent‐free, low‐energy catalysis. ABSTRACT Estolides are oligomers composed of fatty acid (FA) monomers linked through secondary ester bonds located along the mid‐chain region.

From muscle fibres to muscle gears: how dynamic fascicle orientation and shape change impact skeletal muscle function

Biological Reviews, EarlyView.
ABSTRACT Skeletal muscle architectural design strongly affects force‐generating capacity and excursion range, and its functional importance to animal and human movement is well founded. Traditionally, this ‘structure–function relation’ has been inferred from architecture measurements with muscles at rest (from anatomical dissections or medical imaging ...
