Shark preferences: Only subtle effects of electromagnetic field exposure and substrate type on small‐spotted catshark (Scyliorhinus canicula) behaviour

Journal of Fish Biology, EarlyView.
Abstract Offshore wind energy plays a crucial role in the transition to low‐carbon power generation. The expansion of offshore wind farms (OWFs) introduces anthropogenic electromagnetic fields (EMFs) from subsea power cables. Elasmobranchs, including sharks and rays, are sensitive to natural electric and magnetic fields used for navigation and prey ...

Climate Change, Demand Uncertainty, and Firms' Investments: Evidence from Planned Power Plants

The Journal of Finance, EarlyView.
ABSTRACT How does demand uncertainty affect firms' investment decisions? We examine this question in the context of electricity‐producing firms' planned investments in new power plants. We measure uncertainty about future electricity demand using plausibly exogenous variation in temperature projections across scientific climate models. The results show

Dynamic Capabilities as Drivers of Circular Business Models: Exploring Direct and Indirect Relationships

Journal of Product Innovation Management, EarlyView.
ABSTRACT Academic Summary Despite the urgent need for a circular economy, firms' transition from linear to circular business models (CBMs) remains slow. While previous research suggests that dynamic capabilities are the key drivers of this transition, it assumes a direct link, overlooking that these capabilities can facilitate change but do not ...

China's Export Surge and the Persistence of Machinery Competitiveness: Panel Evidence From 25 Countries

The World Economy, EarlyView.
ABSTRACT China's rapid ascent as a global machinery exporter raises fundamental questions about competitive resilience of incumbent economies. This paper examines whether China's gains in revealed comparative advantage (RCA) are associated with declining competitive positions among 24 incumbent economies and whether such changes coincide with ...

Numerical Investigation in the Vaned Distributor under Different Guide Vanes Openings of a Pump Turbine in Pump Mode

Journal of Applied Fluid Mechanics, 2016
The performance of a pump turbine in pump mode is of great importance to a pumped storage power plant. In order to obtain the pump characteristics of a pump turbine, 3D steady simulations were carried out by solving rans using different two-equation ...

Uncertainty Quantification and Attribution for Resilient Infrastructure Systems

Climate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
Infrastructure resilience is critical for maintaining the delivery of essential services to society. However, although computational modelling is integral to infrastructure management, infrastructure model outputs are conditional on a range of uncertain assumptions, both in the present day and under future climate change.

Exercise Intolerance in Young Physically Active Smokers Compared to Non‐Smokers During Sinusoidal Cycling

European Journal of Sport Science, Volume 26, Issue 9, September 2026.
ABSTRACT The impact of cigarette smoking on the cardiorespiratory response to exhaustive exercise remains unclear. This study investigated the smoking effect on exercise tolerance by analyzing the cardiorespiratory and metabolic variables during an exhausting sinusoidal exercise in young physically active smokers (SM) without known cardiovascular and ...

Pump turbines in existing powerplants

, 2019
En brukervennlig metode for å designe kontraroterende aksialpumper har blitt utviklet ved bruk av Matlab. Grafiske brukergrensesnitt har blitt laget for å skrive inn designparametre og å vise designresultater. Designmetoden benytter seg av eksisterende løftelinjeteori for design og optimalisering av kontraroterende propeller, men den er modifisert for ...
