Liberación de sales alcalinas y volátiles del carbón que afectan componentes internos en sistemas de combustión de lecho fluidizado

open access: yesRevista de Metalurgia, 2003
A pesar de las ventajas potenciales de los sistemas atmosféricos de lecho fluidizado, la experiencia ha demostrado que, bajo ciertas atmósferas y condiciones de operación, un material que se emplea como componente interno podría experimentar una falla y ...

Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

open access: yesEcological Entomology, Volume 51, Issue 5, Page 1025-1035, October 2026.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Viewpoint: Toward Sustainable Green Inflammatory Bowel Disease Care

open access: yesJCC Plus, Volume 1, Issue 5, September 2026.
ABSTRACT Climate change is increasingly recognized as a major determinant of human health, whereas healthcare systems themselves contribute substantially to ecosystem degradation. Inflammatory bowel disease (IBD) is a chronic disease that requires long‐term monitoring, frequent endoscopic procedures, ongoing pharmacological therapy, and potentially ...

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Modelling of the coupling hydrodynamic transfer for a gas-liquid countercurrent flow on a wavy surface [PDF]

open access: yes, 2003
This paper concerns laminar countercurrent gas–liquid flow over a wavy wall column, in the case of a falling liquid film. The modelling concerns the coupling of hydrodynamic and heat and mass transfer for an absorption as an example of application.

CO2 Emissions From Rivers Draining the Tibetan Plateau Reveal Substantial Increases Over the Past 20 Years

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 9, September 2026.
Abstract Inland water CO2 emissions are a critical component of the global carbon cycle, yet their magnitude and long‐term response to climate change remain poorly constrained, primarily because of uncertainties in the air–water CO2 concentration gradient.

A 4D geometric morphometrics workflow to quantify complex biological motion

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 9, Page 2616-2628, September 2026.
Abstract Quantifying biological motion is fundamentally tied to quantifying the biological structures that produce that motion. Yet, this dependence makes it essential to decouple motion from static morphology to enable general, comparable analyses across individuals and conditions. In this work, we present a methodological pipeline to study biological
