Oxide Gabbros: Transformation From Oceanic Ridge‐Transform Systems to Subduction

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Fluid composition and fluxes in subduction zones are primarily governed by the nature and degree of hydrothermal alteration of the subducting oceanic lithosphere. However, spatial and temporal heterogeneities inherited from mid‐ocean ridge and oceanic transform fault (OTF) systems introduce significant uncertainties in constraining these fluid

Hipertensión y su relación con el sodio, el potasio, el calcio y el magnesio

Perspectivas en Nutrición Humana, 2006
La presión arterial (PA) elevada es uno de los principales factores de riesgo de la enfermedad, cardiaca, cerebrovascular y renal. Su aumento se debe entre otros a factores dietéticos, genéticos y a sus interacciones, entre otros.

Rupture and Relamination of Continental Lithosphere in a Subduction System (Variscan Orogeny, SW Iberia)

Tectonics, Volume 44, Issue 7, July 2025.
Abstract Relamination is closely connected to subduction zones. Despite the numerous high‐P metamorphic belts recognized on Earth, relamination remains a poorly documented process. We present a continental subduction zone where the exhuming high‐P rocks became a relaminant under the upper plate.

Phase Equilibria Analysis for Metacarbonate With Applications to Zoned Calc‐Silicate Aureoles

Journal of Metamorphic Geology, Volume 43, Issue 5, Page 445-465, June 2025.
ABSTRACT Carbonate rocks react with infiltrating hydrothermal fluids to produce zoned calcsilicate assemblages in contact aureoles. Petrogenetic grids provide valuable insights into phase relations, metamorphic temperature (T) and the fluid composition (X) of the metacarbonate systems, as well as semi‐quantification of the prograde decarbonation at ...

Strong scale‐dependent relationships between fine‐root function and soil properties uncovered with spatially coupled sampling

New Phytologist, Volume 246, Issue 6, Page 2506-2521, June 2025.
Summary Substantial fine‐root trait variation is found at fine spatial scales but rarely linked to edaphic variation. We assessed the spatial scales of variation in fine‐root traits and adjacent soils using a spatially coupled, nested sampling scheme along a fertility gradient in a seasonally dry tropical forest tree, Handroanthus ochraceus.

Intercambio cationico calcio-magnesio-sodio en algunos suelos del Valle del Cauca

Acta Agronómica, 1989
Para estudiar la influencia de diferentes cantidades de Ca, Mg y Na en las aguas de riego sobre las propiedades químicas y físicas de los suelos, se caracterizó el intercambio Ca-Mg en presencia de diferentes saturaciones de Na en la solución de ...

Melt‐Supported Strain Localization at Eclogite‐Facies Conditions Triggered by Syn‐Metamorphic Strength Inversion

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract In convergent high‐pressure settings dominated by dry mafic rocks, strain has been proposed to be predominantly localized in eclogite. However, the processes initiating strain localization, accommodating strain and rheological consequences remain to be identified.

Marcadores de estrés oxidativo en hipertensión leve

Anales de la Facultad de Medicina, 2007
Introducción: La hipertensión es un factor de riesgo cardiovascular y en 90% de los casos se desconoce el mecanismo que la inicia. Recientemente, se considera que la hipertensión es un síndrome de anormalidades metabólicas y estructurales, en el que las ...

Synthesis of a National Soil Dataset Across Productive Land in Mexico: The Importance of Making Existing Data Accessible

European Journal of Soil Science, Volume 76, Issue 3, May–June 2025.
ABSTRACT The lack of soil data is a complication that most soil scientists will encounter throughout their career; this critical aspect is exacerbated due to the excessive cost of soil surveying. Consequently, it is essential to develop strategies that guarantee the permanent accessibility of past soil sampling efforts.
