Unsteady wake modelling for tidal current turbines [PDF]
, 2011 The authors present a numerical model for three-dimensional unsteady wake calculations for tidal turbines. Since wakes are characterised by the shedding of a vortex sheet from the rotor blades, the model is based on the vorticity transport equations.

The parameterisation of turbulence in the marine environment [PDF]
, 2016 There are many problems in the fields of flow modelling around structures and tidal stream energy yield analysis which require a thorough understanding of the turbulent and time-averaged flow speeds in marine environments.

Evolution of secondary cellular circulation flow above submarine bedforms imaged by remote sensing techniques [PDF]
, 2013 Normalized radar cross section (NRCS) modulation and acoustic Doppler current profiler (ADCP) measurements above submarine sand ribbons and sand waves are presented. The two study areas are located in the Southern Bight of the North Sea at the Birkenfels

Journal of the Waterways, Harbors and Coastal Engineering Division, 1970 The classic, and most effective way to prevent the spread of oil spilled in harbors is by surrounding the spill with a floating barrier, or boom In calm water, with no currents, early devices made from telephone poles and canvas were more or less effective In the presence of currents, however, and particularly with larger spills, the problem rapidly ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Journal of Marine Science and Engineering, 2021 An integrated wave-tidal current power turbine is affected by both wave and tidal current forces, and its energy efficiency is closely related to the velocity and direction of the two forces.
