Dynamic Characteristics Analysis of a Large Wind Turbine Gearbox Supported by Journal Bearings Under Different Lubrication States

open access: yesWind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT Due to their superior load density, planetary gear journal bearings (PGJB) are progressively replacing rolling element bearings in wind turbine gearboxes; therefore, accurately revealing the dynamic characteristics of drivetrains supported by these bearings under variable operating conditions is crucial for ensuring operational reliability ...

Research on Dynamic Characteristics of Electromechanical Coupling for the Ultra‐Compact Wind Turbines

open access: yesWind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT With the development of ultra‐compact wind turbines, the electromechanical coupling dynamic characteristics of integrated gearbox‐generator systems in their drive trains have attracted increasing attention. To reveal these characteristics, an electromechanical coupling dynamic model is established using the lumped parameter method and the ...

Postembryonic development of the predatory strike mechanics in a praying mantis (Insecta: Mantodea)

open access: yesPhysiological Entomology, Volume 51, Issue 3, Page 377-396, September 2026.
Praying mantis forelegs capture prey using specific kinematic and kinetic traits that change in size and morphology during postembryonic growth and sexual dimorphism influences these dynamics. Strike forces grow hyperallometrically with body weight; larger mantises show longer strike durations, slower joint angular velocities and increased tibia ...

Commercially Exploited Seaweed Species in Africa: Occurrences, Chemical Composition, Current Value Chain and Opportunities for Value Addition

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
Commercially exploited seaweed species in Africa, their biochemical composition, current uses, and value chain are reviewed. Potential value‐addition of seaweed is suggested regionally in Africa amongst countries producing similar seaweed species. ABSTRACT Africa has a wide range of coastal environments that support a diverse array of seaweed species ...
