Ocean Energy: Using the Ocean's Tides, Waves, and Heat to Generate Electricity [PDF]

open access: yes, 2006
Key facts: - The oceans' tides, waves, current, and heat can be used to generate electricity. These resources are renewable, because the moon's gravity drives tides, and winds create waves.

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

Potential Hydrodynamic Impacts and Performances of Commercial-Scale Turbine Arrays in the Strait of Larantuka, Indonesia

open access: yesJournal of Marine Science and Engineering, 2020
The Strait of Larantuka, with highly energetic tidal stream currents reaching speeds of up to 3−4 m/s, is a promising site for renewable electricity production from the ocean. This paper presents the results of an assessment regarding the potential

Hydrodynamic changes in Guadalquivir estuary (Spain) due to a hypothetical tidal marsh restoration project [PDF]

open access: yes, 2018
Tidal marsh restoration will be an important management issue in Guadalquivir Estuary in the near future. The Guadalquivir Estuary has been anthropologically modified several times, the river is bounded by embankments to protect rice and cotton ...

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Development of Individual Rotor Mutual Induction (IRMI) Method for Coaxial Counter-Rotating Rotor

open access: yesApplied Sciences
A coaxial counter-rotating rotor (CCRR), which has two rotors rotating in the opposite directions on the same axis, is seen as a promising technology for low-cost floating tidal current/ocean current power generation using single-point mooring, as the ...

Wetlands Evaluation for Philbrick\u27s Pond Marsh Drainage Evaluation North Hampton, NH [PDF]

open access: yes, 2018
Philbrick’s Pond is a lagoon type estuary that formed landward of barrier beach spits in North Hampton, NH. Its inlet was stabilized and restricted by the road that is now Route 1A or Ocean Boulevard.

Variability of tidal current, density stratification and tidal flat sediment in a tidal river [PDF]

open access: yesWIT Transactions on Ecology and the Environment, Vol 88, 2006
Long-duration observations of tidal currents, stratification, and suspended sediment (SS) were conducted using moored acoustic Doppler current profilers (aDcps) and CTDs in the Ohta flood-way where flow and density conditions change significantly. Spatial variation of SS transport was examined from simultaneous measurements at longitudinal two places ...

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients

open access: yesThe Anatomical Record, EarlyView.
Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.
