Transient thermoelastohydrodynamic lubrication analysis of an involute spur gear
Tribology International, 2004 Abstract A meshing of a gear is a typical example where non-stationary condition exists. Load, velocity, curvature of meshing point vary along the line of action at any time. A complete numerical solution to the transient thermoelastohydrodynamic lubrication (EHL) problem of an involute spur gear is obtained by using simplified multigrid method.

Concussed: Unintended Consequences of the Guardian Cap Mandate in the NFL
Southern Economic Journal, EarlyView.ABSTRACT Guardian Caps are padded shells worn over American football helmets to cushion impacts and reduce concussion risks. In 2022, the NFL mandated their use for specific position groups during preseason practices, later expanding this requirement. While the league praised the Caps for enhancing player safety, skeptics argue they may promote riskier

AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology
International Journal of Urban and Regional Research, EarlyView.Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,
