Digest of Middle East Studies, Volume 34, Issue 3, Summer 2025.ABSTRACT The Arab Spring resulted in an expansion of social and individual freedoms in Tunisian society, but it also brought political instability, negatively impacting what had long been the country's primary source of employment—tourism. This economic crisis forced many to improvise their own sources of income, and it was in this context that a new ...

Global Fossil Methane Emissions Constrained by Multi‐Isotopic Atmospheric Methane Histories
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.Abstract The global CH4 budget of sources and sinks is highly uncertain, particularly the emissions from specific sources such as fossil fuels (FF) or agriculture. Here, we estimate plausible global CH4 source and sink scenarios using historical observations and simulations of atmospheric CH4 mole fraction and its stable isotopic (δ13C‐CH4, δD‐CH4) and

Distributed multi‐layer control of hybrid AC/DC grids: Design and experimental validation
IET Renewable Power Generation, Volume 18, Issue S1, Page 4414-4425, 18 December 2024.The decentralisation of the electrical system requires the development of new control algorithms to compensate for the intermittent and non‐deterministic nature of renewable energy sources and emerging electrical loads. This paper proposes a distributed multilayer control scheme based on model predictive control, applied across various portions of the ...

MERIDA HRES: A new high‐resolution reanalysis dataset for Italy
Meteorological Applications, Volume 31, Issue 6, November/December 2024.Power utilities emphasize high‐resolution reanalysis datasets for resilience planning against extreme weather. Ricerca Sul Sistema Energetico (RSE) S.p.A. developed MERIDA HRES, a 4‐km resolution dataset for Italy, available from 1986 to present. Validated against MERIDA (7 km) and ERA5, it excels in capturing precipitation and wind extremes despite a ...

IET Renewable Power Generation, Volume 18, Issue 15, Page 3112-3126, 16 November 2024.Techno‐economic analysis for floating offshore wind farms in the Mediterranean Sea. The case study was in Sardina (Italy) for a wind farm of 1 GW. Proposal is made for green hydrogen production during curtailments. Abstract Bringing floating offshore wind turbines (FOWTs) to a real industrial maturity and reducing the levelized cost of floating wind ...

Sobre la evolución de los balances energéticos de la agricultura española, 1950-2000 [PDF]
, 2006 On the one hand, this article reviews the works presented on energetic analysis of Spanish agrarian systems since the 80's and, at the same time, we emphasize the originality and validity of those texts. On the other hand, we update to 2000 the estimates

Advanced Energy and Sustainability Research, Volume 5, Issue 9, September 2024.Perovskite halide vacancies are the primary reactive sites for hydrogen generation, withstanding a positive contribution of low loaded g‐C3N4, in reducing carrier recombination. For nitrogen reduction, instead, the active sites are g‐C3N4 nitrogen vacancies, and the heterojunction best performs at low perovskites loadings, as the composites maximize ...
