Reduction of contact stresses using involute gears with asymmetric teeth [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2015 Asymmetrical involute gears have a different value of the operating pressure angle for right and left side of the gear. These teeth are suitable for one direction of rotation. Such teeth enable to change the length of the generating line.

International Journal of Urban and Regional Research, EarlyView.Abstract This article engages signage as a medium through which urban stakeholders negotiate the politics of housing redevelopment and gentrification in cities. Focusing on Toronto, we examine housing‐related signage in three neighbourhoods where social mix approaches to redevelopment have ushered in gentrification: Parkdale, Regent Park, and Moss Park.

Spontaneous unidirectional rotation of a symmetric gear driven by spherical active particles
National Science OpenTime reversal asymmetry and spatial anisotropy are considered two prerequisites for Brownian ratchet. An intriguing realization can be achieved by placing an asymmetric gear in the suspension of motile rod-like bacteria.
