Trendelenburg positioning with or without norepinephrine infusion for haemodynamic support in anaesthetised hypovolemic horses

Equine Veterinary Journal, EarlyView.
Abstract Background Intraoperative haemorrhage during equine anaesthesia is a rare but potentially fatal complication requiring prompt haemodynamic support. Postural manoeuvres such as Trendelenburg (TL) positioning and vasopressor support augment venous return and improve cardiac output (CO), yet their efficacy in anaesthetised hypovolemic horses ...

A simplified two‐station approach for modeling metabolism in dam tailwaters subject to diel flow variation

Limnology and Oceanography: Methods, EarlyView.
Abstract Tailwaters are ubiquitous and highly managed ecosystems whose food webs often rely disproportionately on autochthonous energy. In situ continuous dissolved oxygen data are increasingly being used to estimate gross primary productivity and ecosystem respiration in rivers, but this approach is complicated in tailwaters, where upriver ...

Exploring Marine Energy Potential in the UK Using a Whole Systems Modelling Approach

Energies, 2017
The key market drivers for marine energy are to reduce carbon emissions, and improve the security and sustainability of supply. There are other technologies that also meet these requirements, and therefore the marine energy market is dependent on the ...

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

mLife, EarlyView.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...

The role of the synoptic‐scale conditions in driving fog and mist during the FATIMA July 2022 Sable Island Field program

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ERA5 hourly 325‐m and 1512‐m (a) convergence and (b) vertical motion (actually pressure change with sign reversed to compare with convergence) over Sable Island around the time of an event. The mist (green) and fog (red) occurrences at the surface station are shown at the bottom of the figures. A 325‐m fitted line convergence was positive for the first

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

River Research and Applications, EarlyView.
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 ...

Modeling the Energy Output from an In-Stream Tidal Turbine Farm

Journal of Computers, 2009
This paper is based on a recent paper presented in the 2007 IEEE SMC conference by the same authors, discussing an approach to predicting energy output from an instream tidal turbine farm. An in-stream tidal turbine is a device for harnessing energy from tidal currents in channels, and functions in a manner similar to a wind turbine.

Using Deep Learning AI to Detect Riparian Vegetation Recovery Following a Major Flood in the Brisbane River

River Research and Applications, EarlyView.
ABSTRACT Post‐flood riparian vegetation recovery demands significant attention; however, the complexity of traditional remote sensing methods often hinders environmental managers from implementing rapid vegetation monitoring. This paper developed a model using a Deep Learning Model within ArcGIS to classify and detect recovery of vegetation with high ...
