An Improved Mesh Stiffness Model for a Gear Tooth With Double Cracks on Both Sides Considering Opened and Closed States

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Research on the failure mechanisms of gears with multiple cracks has gained widespread attention. Among these, the study of the mesh stiffness characteristics of gears with multiple cracks is crucial for optimizing gear design and improving transmission reliability.

Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...

Anthropological, Pathological, and Historical Analyses of a Mummified Cranium From Bolivia Hosted in the Museum of Cantonal Archaeology and History of Lausanne, Switzerland

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The past decade has seen a worldwide tendency to re‐examine human remains found in old museum collections. These studies look at the provenance of the remains, the way they ended up in specific collections, the context from which they are likely issued, and all the parameters implicated in their current presence in museum custody.

Investigating the threat to Sitka spruce from Ips typographus: discrimination and colonization of Britain's principal commercial conifer by a damaging forest pest

Pest Management Science, EarlyView.
The forest pest Ips typographus was found to demonstrate attraction to Sitka spruce, and to colonize and breed upon cut logs as successfully as its primary host Norway spruce. This has implications for the beetle's establishment and impact in Sitka‐growing regions, including Britain where I.
