Carbon Isotope and Abundance Systematics Reveal an Insignificant Crustal Sink of Mantle‐Derived CO 2 in On‐Land Rift Zone Geothermal Systems

Barbara I. Kleine, Maud J. Smit, Diego I. Toro Vivanco, Émilie Thomassot et autres

Abstract Rift zones, both on land and submarine, are key pathways for mantle‐derived CO 2 degassing to the Earth's surface. Fixation of CO 2 as carbonates plays a critical role in regulating these emissions. This study examines carbon abundance and isotope compositions …

Enhancing Walking Performance With a Bilateral Hip Exoskeleton Assistance in Individuals With Above-Knee Amputation

Chiara Livolsi, Clara Beatriz Sanz-Morère, Andrea Pergolini, Antonella Giffone et autres

Transfemoral amputation is a debilitating condition that leads to long-term mobility restriction and secondary disorders that negatively affect the quality of life of millions of individuals worldwide. Currently available prostheses are not able to restore energetically efficient and functional gait, thus, recently, …

Diffuse emission of 3He and 4He and thermal energy released in volcanic systems

Mar Alonso, Nemesio M. Pérez, Pedro A. Hernández, Eleazar Padrón et autres

Active or recent volcanism indicates the presence of high-enthalpy resources at depth. This is obvious when visible surface emanations as volcanic plumes, fumaroles, solfataras or bubblings appear. However, visible manifestations of deep anomalies do not always appear at the surface, making more …
