Citizens Turning Into Scientists: A Calling to Boost the Knowledge of the Public to Address the Environmental Crisis in the Brazilian Semiarid 从公众到科学家:助力提升公众知识以应对巴西半干旱地区环境危机

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 546-554, December 2025.
Desertification is increasing in the Brazilian Semiarid, leading to loss of species and ecosystem services, while precise data on biodiversity distribution and trends are lacking. Public engagement in scientific projects can improve ecosystem protection.

Development of a Computational Fluid Dynamics Simulation Model for a Horizontal Axis Tidal Stream Turbine [PDF]

open access: yes, 2014
Tidal stream turbines have generated significant research interests due to their major advantages over some other forms of renewable generation. As this technology is relatively new, deployment of tidal turbines is hindered by various problems.

Unsteady Hydrodynamics of Tidal Stream Turbines

open access: yes, 2013
The unsteady hydrodynamics of tidal stream turbines have been investigated using numerical methods and experiments. Dynamic inflow, which represents the change in backflow induced by the circulation present in the wake due to variations in rotor loading, is the particular focus of this work.

Response‐Based Prediction of Tidal Currents

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 12, December 2025.
Abstract This study evaluates the response method for predicting tidal currents. We introduce a coupled response model which explicitly accounts for interactions between velocity components. By leveraging non‐parametric and data‐driven weight estimation, the approach demonstrates superior predictive accuracy compared to classical harmonic analysis (HA),

Can Tidal Current Energy Provide Base Load?

open access: yesEnergies, 2013
Tidal energy belongs to the class of intermittent but predictable renewable energy sources. In this paper, we consider a compact set of geographically diverse locations, which have been assessed to have significant tidal stream energy, and attempt to ...

Economic analysis of tidal stream turbine arrays: a review

open access: yes, 2021
This tidal stream energy industry has to date been comprised of small demonstrator projects made up of one to a four turbines. However, there are currently plans to expand to commercially sized projects with tens of turbines or more. As the industry moves to large-scale arrays for the first time, there has been a push to develop tools to optimise the ...

Potential of sugarcane bagasse as feedstock for biogas production in Nigeria

open access: yesBiofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 2092-2104, November/December 2025.
Abstract The Nigerian government’s interest in expanding the sugar sector has significantly increased sugarcane production, generating substantial bagasse by‐products without adequate waste management strategies. This study examined the potential of sugarcane bagasse as a biogas feedstock by integrating a socioeconomic survey of 120 sugarcane farmers ...
