Comparison of analysis and experiment for gearbox noise [PDF]

open access: yes, 1992
Low contact ratio spur gears were tested in the NASA gear-noise rig to study the noise radiated from the top of the gearbox. Experimental results were compared with a NASA acoustics code to validate the code for predicting transmission noise.

Strategic Roadmap for Addressing Microplastic Pollution in the Global South: Bridging Monitoring Gaps, Harmonizing Methods, and Building Analytical Capacity

open access: yesEnvironmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastic (MP) pollution represents a growing environmental challenge, especially in tropical and subtropical coastal regions of the Global South, where methodological fragmentation, funding discontinuity, and dependence on external analytical infrastructure limit the production of comparable data and the formulation of evidence‐based ...

The design and analysis of single flank transmission error tester for loaded gears [PDF]

open access: yes
To strengthen the understanding of gear transmission error and to verify mathematical models which predict them, a test stand that will measure the transmission error of gear pairs under design loads has been investigated.

Unveiling Gender Inequities in Small‐Scale Fisheries and Aquaculture in East Africa: a Harvard Analytical Framework Approach

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Small‐scale fisheries and aquaculture constitute critical pillars of food security, livelihoods, and rural economies across East Africa, yet persistent gendered inequalities continue to constrain both equity and sectoral performance. This study provides a synthesis of empirical evidence from Kenya, Uganda, and Tanzania to examine how ...

The Southern California Healthcare Delivery Science Center: A Model for Aligning Patients, Healthcare Systems, and Researchers to Develop, Test, and Disseminate Innovations to Achieve Health Equity

open access: yesLearning Health Systems, Volume 10, Issue 2, April 2026.
ABSTRACT Introduction A key barrier to translating evidence into practice is the paucity of learning health system (LHS) researchers elucidating and addressing barriers to implementation and maintenance. Methods In response to the growing need for a workforce dedicated to translating evidence into practice, we developed the Southern California ...

Aspects of Coulomb damping in rotors supported on hydrodynamic bearings [PDF]

open access: yes, 1982
The paper is concerned with the effect of friction in drive couplings on the non-sychronous whirling of a shaft. A simplified model is used to demonstrate the effect of large coupling misalignments on the stability of the system.

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)

open access: yesFisheries Management and Ecology, Volume 33, Issue 2, Page 246-259, April 2026.
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...
