Riverine Migration Success of Salmonid Smolts Following Their Entrainment in a Hydropower Off‐Channel Diversion in an Upland River

open access: yesRiver Research and Applications, Volume 42, Issue 6, Page 1272-1282, July 2026.
ABSTRACT Salmonid fishes typically express anadromy. During their juvenile riverine emigration, their downstream movements can be inhibited by hydropower schemes that entrain fish in their intakes. Here, the riverine migration success of smolts of brown trout Salmo trutta (“trout smolt”) and Atlantic salmon Salmo salar smolts (“salmon smolt”) was ...

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

open access: yesSmall, Volume 22, Issue 39, 13 July 2026.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Flow‐controlled expiration improves gas exchange in anaesthetised horses undergoing orthopaedic surgery

open access: yesEquine Veterinary Journal, Volume 58, Issue 4, Page 917-924, July 2026.
Abstract Background Flow‐controlled expiration (FLEX) has been shown to significantly enhance oxygenation in horses under laboratory conditions. Objective This study aims to corroborate these findings by evaluating the effects of FLEX on gas exchange in a randomised clinical trial involving a large population of clinical horses undergoing orthopaedic ...

One-Dimensional Modelling of Marine Current Turbine Runaway Behaviour

open access: yesEnergies, 2016
If a turbine loses its electrical load, it will rotate freely and increase speed, eventually achieving that rotational speed which produces zero net torque. This is known as a runaway situation.

The effects of breath holding during high‐intensity land‐based ergometry in swimmers

open access: yesPhysiological Reports, Volume 14, Issue 13, July 2026.
Abstract The aim of this study was to compare cardiorespiratory responses during high‐intensity land‐based exercise between free‐breathing and breath‐holding conditions in swimmers. Twenty varsity swimmers (20 ± 2 years, 10 females) performed 20 s bouts of simultaneous arm and leg ergometry exercise at high intensity (total power output = 606 ± 76 W ...

The distribution and tapping tidal energy

open access: yesOceanologia, 2004
Tidal power along tidal shores has been used for centuries to run small tidal mills. Generating electricity by tapping tidal power proved to be very successful only in the last century through the tidal power plant constructed in 1967 in La Rance,

The effect of tidal currents on the hydrodynamics of tidal turbine systems

open access: yesBIO Web of Conferences
The ocean is a highly potential source of renewable energy with various forms, including wave and tidal energy. Due to its vast composition, the ocean stores and transfers significant amounts of energy. This study focuses on analyzing tidal dynamics that affect the stability of tidal turbines.
