Amphibole textures, and Sr and U-Th radiogenic compositions revealing changes in magma dynamics at Guallatiri volcano (18°25′ S, 69°05’ W), northern Chile..2026. Pérez-Sanhueza, G.; González Maurel, O.; Godoy, B.;Rodríguez, I.; Petrus le Roux.; Guzmán-Marusić, G.; Dosseto, A.; Dux, F.; Bertin, L.
Guallatiri, an andesitic-to-dacitic composite volcano, records a complex magmatic evolution during the ascent of magmas through the crust, which is divided into two main eruptive stages. The Early Stage (∼130
Degradation and projected lifetime of polycrystalline silicon photovoltaic modules after 10 years of field exposure in the Atacama Desert.2026. Osorio.L; Duchêne. L; Tuninetti.V; Narayan.S ; Moreno-Espino.M ; Rivera.M.
This study quantifies degradation and projects the useful lifetime of polycrystalline silicon photovoltaic (PV) modules operating in the Atacama Desert, using I–V measurements taken after ten years of field exposure.
Magma storage conditions of Navidad cone and its relation with the latest eruptions of Lonquimay volcano, Andean Southern Volcanic Zone.2026. Riquelme Ríos, S.; Rodríguez, I.; Godoy, B.; González Maurel, O.; Petrus le Roux.; Ramírez, E.; Geiger, H.; Acuña, A.; Guzmán Marusic, G.; Chanqueo, S.
The Lonquimay-Tolguaca Volcanic Complex is constituted by Lonquimay volcano and Cordón Fisural Oriental, including the Navidad cone. An initial emplacement at 35–40 km depth, with different levels of crustal storage during
Energy and Exergy Assessment of a 250 MW Steam Boiler Under Partial Load Conditions: Comparative Analysis of Fuel Oil and Enhanced Crude Oil. 2026. Retirado-Mediaceja; Quitiaquez.Y; Camaraza-Medina. W, Laurencio-Alfonso. Y; Zalazar.H.L; Palma.C; Angulo Cruz.H.J; Hernández-Wolpez.B.L; Liomnis Osorio.M.
This study presents a comprehensive thermo-energetic and exergetic assessment of a 250 MW steam boiler in a Cuban thermal power plant, operating under partial load conditions (plant: 62–66%; boiler: 58–61%).
How to use lumped damage mechanics: Two-dimensional solids.2026. V.C. Guimaraes, P.; Chang-Qi Pan.; A. Picón, R.; L.N.F. Amorim, D.; Yan-Gao Hu.; P.B. Proença, S.; Flórez López, J
This paper proposes an extension of Jean Lemaitre’s Continuum Damage Mechanics (CDM) into a unified framework denoted Lumped Damage Mechanics (LDM), capable of integrating diffuse micro-damage and localized fracture processes.
Low-order parametric modeling and control of air–fuel loops in industrial rotary dryers: A passive system identification approach.2026. “Rodríguez-Durán. V.G; Montero-Góngora.D; Columbié-Navarro.Á.O; Retirado-Mediaceja. Y; Zalazar.C; Narayan.S; Osorio.L.
Industrial rotary dryers with combustion chambers are among the most energy-intensive unit operations in nickel laterite processing, often operating below 50% thermal efficiency. This study develops low-order linear models for
