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 ...

Education in a Changing Climate: A Systematic Review for Low and Middle‐Income Countries (LMICs)
Sustainable Development, EarlyView.ABSTRACT Climate change is a major global challenge that affects many aspects of human life and hinders progress on the United Nations (UN) Sustainable Development Goals (SDGs). One area that has not received enough attention is its impact on children's education in low‐ and middle‐income countries (LMICs), which are especially vulnerable to ...

Effect of shot peening on surface fatigue life of carburized and hardened AISI 9310 spur gears [PDF]
Surface fatigue tests were conducted on two groups of AISI 9310 spur gears. Both groups were manufactured with standard ground tooth surfaces, with the second group subjected to an additional shot peening process on the gear tooth flanks.
