Biological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Dynamic Capacity and Surface Fatigue Life for Spur and Helical Gears [PDF]
A mathematical model for surface fatigue life of gear, pinion, or entire meshing gear train is given. The theory is based on a previous statistical approach for rolling-element bearings. Equations are presented which give the dynamic capacity of the gear

Centrifugal regulator for control of deployment rates of deployable elements [PDF]
, 1980 The requirements, design, and performance of a centrifugal regulator aimed at limiting deployment rates of deployable elements are discussed. The overall mechanism is comprised of four distinct functional parts in a machined housing: (1) the centrifugal ...

Dream is an offshore flame: Notes on archaeology and belonging
Anthropology and Humanism, Volume 51, Issue 1, June 2026.Abstract Set within an archaeology lab in Dunedin, Aotearoa, this creative non‐fiction piece traces the search for dwelling through the meticulous, repetitive labor of everyday practice. The narrative finds belonging not as a static identity, but as a continuous, tactile engagement with the material world.

Multi-mesh gear dynamics program evaluation and enhancements [PDF]
A multiple mesh gear dynamics computer program was continually developed and modified during the last four years. The program can handle epicyclic gear systems as well as single mesh systems with internal, buttress, or helical tooth forms.
