The Ancient Greek Datives in ‐essi: Contact or Independent Innovations?1

open access: yesTransactions of the Philological Society, Volume 121, Issue 3, Page 357-381, November 2023., 2023
Abstract The Ancient Greek datives in ‐essi have posed a longstanding challenge in Greek linguistics, with their traditional categorisation as ‘Aeolic’ but their widespread presence across Aeolic and non‐Aeolic regions. This article investigates the origin and diffusion of this trait, examining both the early Greek evidence (in particular the Lesbian ...

Detection of wind turbines rotary motion by birds: A matter of speed and contrast

open access: yesConservation Science and Practice, Volume 5, Issue 10, October 2023., 2023
Some bird species may detect low‐speed rotation on wind turbines as static. A low contrast between the wind turbine and its background increases the rotation speed treshold at which this phenomenon appears. Automatic Detection Systems used to slow down wind turbines when birds are approaching may thus be counterproductive.

Characteristics of the low‐level jets observed over Dunkerque (North Sea French coast) using 4 years of wind lidar data

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 149, Issue 754, Page 1745-1768, July 2023 Part A., 2023
The jets' characteristics and variability have, on the whole, a low sensitivity to the continuity criteria used for detection. The jet core height and speed distributions, along with the annual cycle of occurrence, correspond to similar studies on sites more to the northeast. However, northeastly afternoon jets are the most frequent type over Dunkerque,

Windfarm collisions in medium‐sized raptors: even increasing populations can suffer strong demographic impacts

open access: yesAnimal Conservation, Volume 26, Issue 2, Page 264-275, April 2023., 2023
We demonstrate on a short‐lived, endangered raptor species, the Lesser kestrel, that additional mortality due to windfarms can have a negative impact on population growth rate. Although the impact is currently moderate, the forecasted decrease in immigration rate, and increase in the number of windfarms at a wider scale, may threaten the recovery of ...

Wind Turbines, Public Acceptance, and Electoral Outcomes

open access: yesSwiss Political Science Review, Volume 28, Issue 4, Page 712-727, December 2022., 2022
Abstract Despite a widespread public support for wind energy in general, wind turbine proposals attract a considerable amount of public opposition. At a time of political commitments to building more wind turbines for climate risk mitigation, we study the potential causes of this opposition and its electoral effects.

Distance to hedgerows drives local repulsion and attraction of wind turbines on bats: Implications for spatial siting

open access: yesJournal of Applied Ecology, Volume 59, Issue 8, Page 2142-2153, August 2022., 2022
This study provides empirical evidence that wind turbines close to optimal habitats such as hedgerows strongly repel bats, while wind turbines located farther away in open areas could attract them. Increased risks of collisions and habitat losses near edges strengthen the importance of keeping wind turbines at a sufficient distance from woody edges (e ...

Optimization-based reactive power control in HVDC-connected wind power plants [PDF]

open access: yes, 2017
One application of high–voltage dc (HVdc) systems is the connection of remotely located offshore wind power plants (WPPs). In these systems, the offshore WPP grid and the synchronous main grid operate in decoupled mode, and the onshore HVdc converter ...

Spatial and Temporal Variations of Water Quality of Mateur Aquifer (Northeastern Tunisia): Suitability for Irrigation and Drinking Purposes

open access: yesJournal of Chemistry, Volume 2018, Issue 1, 2018., 2018
The present study aims to assess the spatial and temporal variations of the hydrochemical characteristics of Mateur aquifer groundwaters, a crucial water resource in the northeast of Tunisia. The aquifer was subject to water quality deterioration due to salinization and nitrate contamination, and a new assessment of water quality was needed.
