Investigation into the tribodynamics of spur gear pairs considering pitch deviations and lubrication
FrictionPitch deviation, a type of longwave deviation, has been demonstrated to be a significant contributor to noise generation in the drive trains of motor vehicles operating at relatively high speeds. To date, numerous studies have investigated the effects of

Effect of two synthetic lubricants on life of AISI 9310 spur gears [PDF]
Spur-gear fatigue tests were conducted with two lubricants using a single lot of consumable-electrode vacuum-melted (CVM) AISI 9310 spur gears. The gears were case carburized and hardened to Rockwell C60. The gear pitch diameter was 8.89 cm.

People and Nature, EarlyView.Abstract Currently, scholarship on education to foster connectedness with nature primarily focuses on children. As adults likewise face the disconnection from nature and play a key role in influencing children, it is important to understand how they perceive, engage in, and benefit from relevant programmes.

Gear mesh compliance modeling [PDF]
A computer model has been constructed to simulate the compliance and load sharing in a spur gear mesh. The model adds the effect of rim deflections to previously developed state-of-the-art gear tooth deflection models.

Existing Sustainability Interventions are Insufficient to Scale Up Cocoa Agroforestry in West Africa
Sustainable Development, EarlyView.ABSTRACT Sustainability transitions in agri‐food systems are required to address climate change, biodiversity loss, and social inequities. In the West African cocoa sector, supply chain sustainability initiatives (SSIs) have emerged as key environmental governance tools to address these challenges and promote agroforestry.
