Research of Gravity Compensation Mechanism based on Non-circular Gear

Jixie chuandong, 2019
At present,most robots need to consume a large amount of energy to overcome their own gravity during operation. In order to reduce energy consumption and improve robot performance,a gravity compensation mechanism（ GCM） for a rotating joint manipulator is

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

Wind 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

Wind 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 ...

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

Reviews 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 ...

Syndromic Convergence in Aquaculture Disease Management: A Critical Review of Climate‐Pathobiome Interactions, Diagnostic Frameworks, and Knowledge Gaps

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Syndromic convergence (SyCo) reframes aquaculture disease as the synergistic product of climate‐driven stressors, pathobiome communities, and host immune compromise, not single pathogens. A five‐criterion scoring matrix, composite early warning index, and three‐layer intervention framework together operationalize this shift toward predictive ...

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.
