The Effectiveness of Shrouding on Reducing Meshed Spur Gear Power Loss - Test Results [PDF]
Gearbox efficiency is reduced at high rotational speeds due to windage drag and viscous effects on rotating, meshed gear components. A goal of NASA aeronautics rotorcraft research is aimed at propulsion technologies that improve efficiency while ...

Predicted effect of dynamic load on pitting fatigue life for low-contact-ratio spur gears [PDF]
How dynamic load affects the surface pitting fatigue life of external spur gears was predicted by using the NASA computer program TELSGE. Parametric studies were performed over a range of various gear parameters modeling low-contact-ratio involute spur ...

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War
Anthropology of Consciousness, EarlyView.ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

We Woke Up With a Sign: Exclusion, Conflict and the Politics of Marine Conservation in South Africa
Area, EarlyView.Short Abstract Conservation often continues to be undertaken in ways that exclude nearby communities, despite extensive critique of such practices. This paper examines the reactions to the creation of a marine protected area in KwaZulu‐Natal. We find that the community supports conservation, but expresses frustration at not being included in decisions ...

Business Ethics, the Environment &Responsibility, EarlyView.ABSTRACT A supportive ethical culture (EC) can encourage moral behavior among employees and help them avoid wrongdoing. One option for fostering EC is ethics training; its longer‐term effectiveness, however, has rarely been examined, especially in countries lacking strong regulatory environments.
