Experimental Analysis and Evaluation of the Numerical Prediction of Wake Characteristics of Tidal Stream Turbine

Energies, 2017
It is important to understand tidal stream turbine performance and flow field, if tidal energy is to advance. The operating condition of a tidal stream turbine with a supporting structure has a significant impact on its performance and wake recovery. The

Tidal Modulation of Energy Dissipation Routes in the Gulf Stream

Geophysical Research Letters, 2023
The Gulf Stream (GS) is a powerful ocean current that is instrumental in regulating the global climate. While a correct reproduction of GS dynamics is contingent on an appropriate representation of energy dissipation, the specific role of tides in ...

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

IMPACT OF TIDAL STREAM ENERGY EXPLOITATION ON ESTUARINE HYDRODYNAMICS [PDF]

Coastal Engineering Proceedings, 2014
During the last years there has been an increasing interest towards the exploitation of marine energies and, in particular, of tidal stream energy. Although the impact of tidal stream farms is expected to be much lesser than that the conventional barrages, there are numerous environmental variables likely to be altered.

Capture of isoflurane from anaesthetised dogs and cats following methadone, medetomidine and ketamine administration

Veterinary Record, EarlyView.
Abstract Background Volatile anaesthetic agents contribute to climate change, and reducing this impact is a commendable ambition. We evaluated the efficiency of a veterinary capture device for isoflurane (VET‐can/VET‐dock, SageTech Veterinary) in anaesthetised cats and dogs.

Multi‐Strategy Synergy‐Based Differential Evolution for Large Wind Farm Layout Optimization

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Exploring clean energy alternatives to fossil fuels has become a major research focus worldwide. Wind energy is regarded as one of the most promising renewable energy sources due to its clean and sustainable nature. However, wake interactions among turbines significantly reduce power conversion efficiency, making wind farm layout optimization (
