Basin Research, Volume 38, Issue 1, January–February 2026.An updated view of the southern part of the Cantabrian‐Pyrenean junction through a 3D geological model shows the first conclusive evidence for the ~65 km‐wide diffuse Pamplona transfer zone linking the Basque‐Cantabrian and Mauleon segments of the Pyrenean rift. This transfer zone also affected the style of deformation and configuration of the Pyrenean

Analysis of Influencing Factors on Particle Deposition in Electric Heater With Segmental Baffles
International Journal of Chemical Engineering, Volume 2026, Issue 1, 2026.Against the backdrop of the “dual carbon” goals, electric heaters have been widely deployed on offshore oil and gas platforms. Nevertheless, salt particle deposition inside such equipment severely endangers the stable operation of facilities. Relying on a laboratory dynamic ethylene glycol desalination experimental setup, this paper performs numerical ...
